4.1 TOXIC AND ANOXIC PHENOMENA ASSOCIATED W工THALGAL BLOOMS

Recommendations:

(i) The IOC and the IOC/WESTPAC Secretariat shou1d convene a working group and commit funds for the creation and distribution of a manua1 on techniques used in fie1d and 1aboratory studies on harmfu1 a1ga1 b1ooms.

豆2盟血豆旦主 This manua1 is to be a compi1a七ion of new ma七eria1七oge七herwi七hexisting pro七oco1s七ha七 arenow sca七七ered七hどoughou七七he 1iteどature. The emphasis shou1d be on 七he species and techniques tha七 are appropriate for 七he WESTPAC region, recognizing七he limi七a七ionsmany countries have with respec七 七oexpensive or high1y technica1 equipmen七 The manua1 wi11 ini七ia11y be distributed to individua1s for commen七s and revisions, and 七hen tested and ref ined fur七her a七 a training workshop. Trans1ation of this manua1 into nationa1 1anguages of 七heWESTPAC coun七ries shou1d be considered as a possib1e fu七ureWESTPAC ac七ivity.

(ii) The IOC and WESTPAC shou1d support the creation and distribution of a regiona1 news1etter on harmfu1 a1ga1 blooms.

Co盟旦皇旦主 This effor七 wi11 on1y succeed if Task Team members active1y contribute to the news1etter. Initia1 efforts to dis七ribute a news1etter twice each year 七o approxima七e1y 100 individua1s wi11 be coordinated by D.M. Anderson (USA) and Rhodora Corra1es (Phi1ippines) bu七七he eventua1 goa1 wi11 be for a publication entire1y sustained by workers from the region.

4.9 ASSESSMENT OF RIVER INPUTS TO THE SEAS 工N THE WESTPAC REGION

Some excellen七 progress has been made on 七he study of mangrove fluxes, bu七 morework in needed for a good unders七anding of 七hese sys七ems.Some good data on con七aminan七s in mussels has been produced but 七his data needs七obe rela七ed, in some cases,七olocal geochemis七ry七oclearly de七erminewhere pollu七ion is occurring.

Reference me七hods for measuring contaminan七 conc.eptra七ions need con七inual upgrading. Modelling may be of assistance in coas七al pollu七ionstudies, but appropriate testing is requiどed.

Estuaries are s七illa major source of scientific con七roversy, bu七some progress has been made on flux determinations.

A七七he IOCjWESTPAC Workshop on River Inpu七s of Nu七rien七s 七0 七heMarine Environmen七 itwas reported that:

A labora七oryintercalibration exercise for nu七どientswillecarried out in 1992; and

There is a need to encourage na七ional agencies 七o include nu七rien七s in river wa七er studies.

A join七 workshopwith the toxic and anoxic phenomena group should be held immediately before the next WESTPAC session.

The following rivers systemsjcountries have been recommended for inclusion in a WESTPAC programme on river inpu七sto nu七どien七s 七o 七hemarine environmen七.

VARIATIONS OF SEA LEVEL AND SEA LEVEL TREND AND THEIR POSSIBLE CAUSES

WOLFGANG D. SCHERER

NOAA, Na七iona1Ocean Seどvice,USA

Re1a七ivesea 1eve1, i.e. sea 1eve1 re1ative to a fixed bench maどkon 1and, of the oceans varies over a wide range of space and time sca1es. Changes in c1imate, tectonics, post-g1acia1 rebound,、subsidence, up1ift, ocean circu1a七ion,a七mosphericpressure, sa1inity and七empera七ure,and七hevo1ume of sea wa七erare a11 causes for changing sea 1eve1. Sea 1eve1 has no七 been cons七ant 七hroughou七ear七h'shis七oryand it is changing now. The forces changing sea 1eve1 no七 on1yvary grea七1ywi七h七imeand space but their re1ative impor七ancea1so change with 七ime.

Sea 1eve1 change, i七samp1itude and spacia1 variation are presented ranging from seasona1 to in七erdecada1七imesca1es. The variabi1i七Y of sea 1eve1 trends both in space and time are a1so examined. An assessment of 七he status and 七hecapabili七ies of new 七echno1ogy of tide gauges and re1ated ins七rumentation is presented. Various ana1ysis 七echniques and approaches 七o examine sea 1eve1 variabi1i七y,sea 1eve1七rendsand its variabi1ity wi11 be stressed. Ana1yses of 10ng 七erm globa1 sea 1evel data are compared with globa1 sea 1eve1 mode1 predic七ions.

YU JIYE, CHEN SHANGJ工, FANG XINHUA

Nationa1 Marine Data and Information Service State Oceanic Administration, China

The 10ng term七imeseries ana1ysis of the SST (Sea Surface Temperature) in the eastern equatoria1 Pacific Ocean and 七hemon七h1y MSL (Mean Sea Leve1) in the 七ropica1 Pacific Ocean is conduc七ed. Their quasiperiodic and 10w frequency oscil1a七ion featuどes are revea1ed. The signif ican七 periods of low frequency f1uc七ua七ionsfor mon七h1yMSL in the area of 20N--20S are between 43.5 months and 50.0 months, approxima七ingc1ose1y七o47.6 mon七hswhich is the significant period of SST in七heeas七ernequatoria1 Pacific Ocean. The 10w frequency f1uc七uationsof mon七hlyMS工 in the 七ropica1 Pacific Ocean appear to have a antic10ck wise circularly propagating pa七tern,which is the eastern Pacific Ocean (off shore of Mexico)ーー 七he area of NEC(North Equatoria1 Current)ーー七he western equatorial Pacific Ocean-七hearea of NECC(North Equatoria1 Counter Current)ーー七heeas七ernequatorial Pacific Ocean.

Based on the resu1七s above, a basic mode1 is es七ab1ished with stepwise regression method, which can forecast E1 Nino even七sby七hevaria七ionsof month1y MSL at a few sta七ions in the tropica1 Pacific Ocean 4 months ahead. The corre1ation coefficien七 betweenthe forecasted series and observed one is 0.89.

In addi七ion,some conc1usions indicate that the intensifica七ion of westward transpor七 by NEC may be the initial どeason causing the accumula七ion of warm

SUSTAINABIL~TY FOR DEVELOPMENT AND THE ENVIRONMENT

Questions concerning an operational definition of sustainabili七yhave been raised on several occasions following release of the wording provided by "The World Commission on Environment and Deve10pmen七" ( WCED ), "Ouど CommonFuture".

As par七 of the concept of "environmentally sound and sustainable development" (ESSD) the WCED defines "sus七ainabledevelopment" as "developmen七七ha七 meetsthe needs of the present withou七 compromisingthe ability of fu七uregenerations to mee七七heirown needs". By itself, the latter statement is unbounded and involves an appeal to "inter-geneどationalequi七y"with the consequent implici七 assump七ion七ha七 increasinglyeffective and efficient technological adjustments regaどdlessof the quali七Y of available resource base.

The rela七ionshipbetween sustainability and development has been addressed on any occasions. The problem involves the necessity for an accommodation between the requiremen七sof po七entiallyun1imited growth and energy use wi七hthe dic七atesof a fini七e system, the second law of thermodyamics and the inevitability of increasing disorder (en七ropy)・

1n a gross sense,七he question of specifying "environmen七a11y sound" invo1ves definition of 七heexten七七o which the globa1 ecosys七ems, which are themse1ves "counter en七ropy", can accommodate the effects of increased en七ropy without 七ermina1break-down.

River flows in a 七idalreach of an estuary consis七 ofa uni-direc七ional fresh wa七erflow towards the mou七hof the es七uaryas well as an oscilla七orycomponent driven by the七ide. Data on such flows and model predic七ionssubjec七七ovarious tidal conditions are needed crucial inpu七 to any water quali七y analysis and prediction.

Direct measuどementsof tide levels and flows at strategic locations enable one to build simple models to simulate such flow regimes. This paper discusses two methods used for such flow analysis. The first me七hod applies the mass conserva七ionof volumetric flux directly to segments of the river七o derive a model of volume七ricflux for a tidal cycle. The second me七hodsolves numerically a one-dimensional hydrodynamic model for the propagation of a long wave through a shallow water sys七emthat conserves both energy and mass.

Comparison between the two methods and their relative meri七swill be discussed using a tidal estuary in Johor as a case s七udy.

Bivalves of七enbecome toxic by ingestion of toxic phytoplankton occuring in the surrounding water. Food poisoning have been occurどed by human consumption of toxic bivalves. Among these poisonings, paralytic shellfish poisoning (PSP) is the mos七 prominen七 becauseof its global occurrence, high incidence of fatality and 七he serious damage i七 causes to shellfish industries. Five species of dinoflagella七es in七hreegenera have been identified as causative organisms of PSP. There are many reports on toxins they produce as well as their taxonomy and ecology. These studies revealed that PSP toxins consis七 of various components which are derivatives of ,saxi七oxin (STX). Toxin profile repor七ed for vaどiousstrains of dinoflagella七es Suggests that it is specific 七o each genus the dinoflagellate belongs. Main toxins in the genus ilexandrium areどepor七edto be gonyautoxin (GTX) 1-4 and their N-sulfocarbamoyl deどivertives, though the varia七ion has been obseどved among the species. Most of all the 七oxins of Gymnodinium ca七ena七um consis七 of N- sulfocarbamoyl deriva七ives of GTX 1-4. pyrodinium bahamens var. compressa shows the characteris七ic七oxinprofile which consis七s of STX, neoSTX and its carbamoyl deどivatives. Many data on七hetoxin composi七ions of bivalves show that toxin profile of bivalve reflec七s that of causative dinoflagella七es. From these,七he causative dinoflagella七es of PSP toxins would be assumed by the analysis of toxins in bivalves.

POSSIBLE ASSOCIATION OF MARlNE BACTERIA WITH DINOFLAGELLATES TOXINS IN BIVALVES

MASAAKI KODAMA

Laboどa七oryof Marine 8iological Chemistry School of Fisheries Sciences Kitasako University, Japan

Paralytic shellfish poisoning (PSP) is one of 七he global pどoblems caused by dinof lagellates. Causa七ive organisms for PSP are several species of dinoflagellates such as Alexandrium tamarense and A. ca七enella. When these species bloom in the environment, bivalves accumula七etoxins by inges七ingthem. It has been confirmed by many researchers that bivalves become toxic during the bloom of七oxicdinoflagellates. In the monitoring survey on the bivalve toxicity and abundance of toxic dinoflagellates on Ofunato 8ay during 1980 and 1986, we also confirmed 七he accumulation of toxin by bivalve during bloom of dinoflagellates. However, we noticed at the same time that these two parameters are no七 always para11el 七。 each other. 8iva1ve toxicity often increased significant1y under absence of toxic dinof1agellates, suggesting the presence of unknown causative organism(s) other than dinof1agel1ates. During七heperiod when bivalve 七oxicity was increasing, we observed tha七 PSP toxins aどe often detec七ed in the par七icles with bacteria size in the seawater. These findings sugges七七ha七 marinebacteria which produce PSP toxins are associated with bivalve toxicity.

Surface and core sediment samples were collected from various sedimenta七ionenvironment in the Chao Phraya River, Thailand in 1988-1989. The samples were analyzed for organic carbon, organic ni七rogen,amino acids, pheao-pigmen七s,total phosphorus and total sulfide contents. Geneどally,surface sedimen七s from七heChao Phraya River were found to con七ain higher contents of all the organic cons七ituentsde七erminedwhen compared wi七h sediments from the Songkla Lake and the pang-nga Bay areas. Apparently, this is due to higher an七hropogenic inputs of organic wastes from the city of Bangkok than less populated areas of Songkla and pang-nga. The atomic ratios of caどbonand nitrogen fluctuated in七herange from 7.1七o 13.3. No positive correlations were found between organic carbon, organic nitrogen, to七alphosphorus and pheaopigments in surface sediments from al1 s七a七ions. These resul七ssuggest tha七 mostorganic matter in these sediments were derived from terrestrial detどitus rather than from in si七u primary production.

The vertical profile of physical and chemical proper七ies of the Chao Phraya es七uarysediments were plotted against depth. Sediment coどeshowed very irregular cyclic s七ratifications. The upper 50 cm sediments contained several, considerably discon七inuous laminae, distinguishable by difference in water con七ents and porosity as well as in organic matter contents. This pattern can be explained on the basis of relative rates of supply of organic ma七七er and terr igenous materials, due to varia七ionswhich might cause differences in types and amoun七of sediment being deposi七ed. The rate of sediment deposi七ionin the estuary was es七imatedto be abou七 10cmjyear a七 station5.

Swa七hbathymetric side-scan sonar (1zanagi) da七areveal a precise bottom surface morphology of back-arc depression in the 1zu-Bonin Ridge. Fig.l shows 1zanangi back sca七七ering image of 5 km swath width from Hachijo depression. The depression, which is located a七 severalkm behind volcanic front, represen七sN-S elongation. Many volcanic mounts ~nd seamounts are recognized in the depression. A charac七eris七ics七どuc七urein the depression is a lineament with a general七rendof N300

- 40OW. The lineament is represented by normal faults and elongated shapes of the mounds and seamoun七s.A equivalent lineamen七 isどecognizedno七 onlyin the Sumisu depression approx. 200 km south of七heHachijo depression bu七 alsoin七heMikura basin 50 km nor七hward. A northward continua七ionof the lineament is inferred to be identified as far as the Hakone caldera located a七 nor七hernmargin of the 1zu-Bonin Ridge, 1zu peninsula. This suggests that a back-arc rifting occurs even in a collision zone between the 1zu-Bonin Ridge and the Honshu Arc.

WEST PACIFIC MARGINAL SEAS IN LAST GLACIATION: PALEOGEOGRAPHY AND ITS ENVIRONMENTAL IMPACT

WANG P1NX1AN

Departmen七 ofMarine Geology Tongji University, China

During七he las七 glacial maximum, the sea level lowering had caused remarkable al七erna七ions in configuration and area of the W.est Pacific marginal seas, Wi七hemergence of the vast shelf areas disappeared (e.g. the Yellow Sea,七heJava Sea) and numerous smal1 island merged into large ones (e.g・the Phil ippines)・Somemarginal seas became enclosed basins (such as the Sea of Japan) or semi enclosed basins with a restricted connection to the open ocean (such as the South China Sea), Sea ice coverage increases significantly in high lati七udeseas (such as the Sea of Okhotsk).

Meanwhile, the glacial pa七七ernsof the oceanic and atmosphere circula七ionwere differen七 from the modern ones. The polar front in 七he Nor七h Pacific, for example, had moved abou七 10of lati七udesou七hwaどd,and七hewesterly winds in the Sou七hwes七 Pacific had shifted significantly to the sou七h. The changes in planetary circulation combined with the local geographic modifica七ions had al七eどed 七he circulation and temperature patterns in the marginal seas. 1n the South China Sea, for example, the modeどn trans- basinal current system was replaced by a semi enclosed circulation pattern and the winter SST was about 60C lower than it is now with a seasonality (9-100C) far exceeding七hat a七 present(4-60C).

The reduction of sea area and the changes in sea circulation sys七emhad led to major changes in a七mosphericcirculation and hence, clima七eon land. As evidenced by the wide-spread eolian deposits and the migra七ion of vege七a七ion zones, continentali七y and aridity were then strengthened in large areas of Asia and Australia, wi七hwinter monsoon intensified and summer monsoon subsided.

THE USES OF PALAEOGEOGRAPH1C MAPS -WESTPAC PALAEOGEOGRAPH1C MAP PROJECT

MAR1TA BRADSHAW

Australian Bureau of Mineral Resources, Australia

The initial aim of七heWESTPAC project is to produce palaeogeographic maps of the WESTPAC region for two Quaternary time slices ー七hepeak of the last glaciation (c.18,000 years B.P.) and the last inter-glacial (c.125,000 years B.P). The maps will be used as a framework for environmental and climate s七udiesincluding七he七es七ing of global circulation models, and may assist explora七ion for mineral placer deposits.

The emphasis of the maps will be on the marine realm,七he offshore and the coas七al zone. the palaeogeographic maps will show the dis七ribution of past enviどonments.There will be accompanying data maps that compile informa七ionabout sediment type and thickness, water salinity and七emperatureand other indicatoどS

of pas七 climate.

A series of palaeogeographic maps of Australia produced by the Bureau of Mineral Resources provide a guide as to the methodology that could be used for the WESTPAC maps palaeogeography is concerned with mapping the dis七どibutionsof land and sea through time. 1t aims to reconstruct the patterns of past environments by in七egratingsedimen七ological,biostratigraphic and tectonic information.

The Bureau of Mineral Resources have produced 70 of these 七ime slice palaeogeographic maps of ~ustralia using the following me七hodology:

i) complication of data sources for each period repoど七, maps, well comple七ionrepor七s;

ii) cons七ruction of summary stratigraphic columns and selec七ion of time slices;

iii) preparation of timeslice data maps showing lithology and 七hickness,paleocurrents, mineral occurrences, outcrop, subcrop, intersec七ions;

iv) preparation of Peどiodstructure mapsi and

v) preparation of in七erpretativePalaeogeographic maps.

The palaeogeographic maps have been used primarily for petroleum exploration though they also have applications in mineral exploration. 工ncreasingly,a use for palaeogeographic maps will be inclimate modelling, a palaeogeographic map provides 七heboundary conditions for global circula七ionmodels where the land, sea and mountains are, and then acts as a tes七 of the model when climatically significan七 faciesare plotted -such as coals, evaporites, reefal limestones and glacial七ills. By developing our abili七y七omodel past climates we will have七heconfidence to model future global climatic change.

VO VAN LANH

1nstitute of Oceanology, Nhatrang, Vietnam

The七otalcuどrentson the shelf was considered as a combination of tidal current and winddriven current. The tidal current was found by me七hod of haどmonicanalysis of measured data and solution of system of hydro-dynamical equa七ions.The winddriven current was calculated by Fenzenbaum' s method with accoun七 ofreal wind stresses and seabed topography. The maximum current velocity was estima七edby approximate solution of nonstable dynamical equations.

The results of investigation are as follows:

1. The maximum current can be caused by wind blowing parallely七o coastal line and the minimum current -by wind blowing normally七o coastal line.

2. The vertical structure of current depends on the angle between wind direction and coastal line.

3. There are two typical regions of currents on the shelf of Sou七h Vietnam region with strong variability of current (with horizon七al gradient of

surface curren七 velocity more than lScm/s/km) and region of relatively stable current (with horizontal gradient of surface curren七 ve10cityless than lScm/s/}αn). The first region is situated nearby the coast and along the sea belt with strong variability of seabed七opography. The region is situated in七herest place.

Foraminiferal moni七oring has been done in the different parts of the nor七hwes七ern shelf of the Black Sea (depth 5-130m, salini七Y 1-18も (Yanko & Flexer, 1991) and offshore Eas七ernMediterranean near工srael(Hadera and Palmahim, dep七hs2-1300m, salinity 35-37も)・ Theseareas are affected by pollution from adjacen七industrial, domestic and agricultural sources.

Bo七h living and fossil benthonic foraminifera from box cores and sedimen七 coreswere s七udied according to general world-wide accep七ed me七hods wi七h some modifications appropriated for the Black Sea (Yanko & Troi七skaya,1987). The following parameters as distribution of foraminiferal species and specimens in space and 七ime,diversi七y,morphological changes of their 七ests (deforma七ion,dis七orted chamber arrangement protuberances on the chambers deforma七ion of aper七ure) and pyritization in both living and fossil foraminifera have been determined. The rela七ivefrequency of foraminiferal benthonic species was七reatedin a Q-mode factor analysis. The concen七rationof pollutan七s in七hesediments has been de七ermined using the methods of gas- chromatography, radiograph spec七rography,fluorescent and atomic absorp七ionanalyses.

Foraminiferal benthonic fauna of the north-western shelf of 七he Black Sea is represen七edby 55 species, 3 of them are agglutina七ed. In inves七iga七edareas of the Eas七ernMediterranean abou七 120mainly calcareous species were found. These fauna are different and i七 isimpossible to es七imate七hereac七ionsof all species to pollu七ion. Tha七.s why only 6 species from genera Ammonia, Porosononion, Quinqueloculina, Miliammina, Discammina, Eggerella were chosed by us as indicators of pollution.

Indica七orsof heavy me七alspollution (especially Pb, Cd, Hg) might be different kinds of test deformationi decrease of bo七h the sizes of specimens and their abundance and increase of megalospheric forms.

In the 81ack Sea which is con七aminatedwi七hH2S bellow dep七hs130-200 m (widespread point of view, bu七 inmany cases we met H2S even on the dep七hs20-30m), pyri七iza七ionin mainly megalospheric specimens Ammonia tepida (Gushman) and Porosononion martcobi 80gdanowicz is widespread.

These places usually are characterized by high pH, low ph, high con七en七 oforganocloride pesticides and abundance of nutrien七sfor foraminifera. Foraminiferal assemblages very similar to above men七ionedones bu七 moreabundant with specimens have been found als。、 inorganic rich sediments of some neo七ectonicuplif七s (for example, the Golythyn High in the north-western inner shelf of the 81ack Sea) which are perspective for oil-gas exploration,

The ben七honicforaminifera contents of samples recovered from七hepollu七edby oil sea-bot七om sedimen七s don'七 give any clear picture in regularities of 七heirdis七ribution. As a rule living benthonic foraminiferal fauna is no七 reachthere and mainly i七 isrepresented by agglutinated forms (Eggerella scabra Williamson, Discammina imperspica Janko, Miliammina fusca 8rady). 8y 七he way, dominant significance of agglutinated foraminifera rather often 七akes place in aquatic se七七ingspollu七edby different ma七七ers.

The use of ben七hbnicforaminifera as indica七orsof pollution has many preferences on comparison with 0七her0どganismbecause foraminifera are shelled organisms of good preserva七ion in sediments; ecological retiremen七 of many species are de七ermined; foraminifera have a short reproduc七ive cycle and can reflec七 ashor七-term environmen七al changes. In addi七ion to, certain foraminiferal assemblages can be used for submarine oil-gas explora七ion.

GEOGRAPH1CAL D1STR1BUT10N AND PER10D1C OCCURRENCE OF TOX1C D1NOFLAGELLATES 1N KOREAN COASTAL WATERS

JOO SUCK PARK

Na七ionalFisheries Research and Development Agency, Korea

The presen七 paperdeals mainly with the geographical distribution and periodic occurrence of nine species of toxic phytoplank七onsuch as Alexandrium tamarense, Dinophysis fortii, Gymnodin七ummikimotoi, Cochlodinium polykrikoides e七c. which caused Paralytic shellfish poisoning (PSP) and fish and shellfish kills in Korean coastal wa七ers and their correla'tion with the occuどどence of PSP in bivalve mo11usks.

The princip1e causes ofどedtides for Chinhae Bay, up to the 1as七 par七 of1970s, were mainly dia七oms. Since 1981, however七hemain causative organism have been flagella七es such as Gymnodinium mikimotoi, Prorocentrum micans, Heterosigma akashiwo and Cochlodinium polykrikoides.

Alexandrium七amarense どesponsible for PSP occurred mainly from April to May in large number, and the PSP of七hebivalve shellfish collec七ed from the southern coas七 ofKorea was most often detected in the sea mussel mainly during the months from March to May.

Massive losses of cultured yellow tail and sea bream due to cochlodinium polykrikoides red七ideshave occured since 1989 in caged fish farms near Chungmu.

LIU HENG AND LIU RUIYU (J.Y. LIU)

Ins七i七u七e of Oceanology, Academia Sinica, China

Theどe are more than 80 species of penaeid shrimps have been recorded in chinese wa七ers (J. Y. Liu e七 al.,1988). About 40 species are considered to be of economic impoど七ance. Among them七hechinese shrimp Penaeus chinensis, red tail shrimp P. penicillatus and banana shrimp P. merguiensis are the mos七 impor七antspecies in bo七h shrimp ca七chand cul七ure.

Because of the grea七 morphologica1similarity of these three species, especially during 七heir larval and postlarval stages, there are still problems for 七heshどimprecruitment forcas七ing・Thepresent study deals with larval and postlarval development of penaeid shrimps in order to provide some basis for distinguishing them. The main larval morphological differences of the three species are concluded as follows

The three species can not be dis七inguishedduring the nauplii stages.

In first zoea s七age,Li/L2 * in anttennula is about 1.7-2.0 in P. meどguiensis,but in P. chinensis and P. penicilla七us is about 1.6; In the second zoea, the supra-orbital spines in P.chinensis are unifurcated, while P. merguiensis and P. penicilla七usare bifurcated; In the third zoea, there is no dorso-median spine in the pos七eriormargin of the firs七 abdominalsomite (for the second somite, it is minute, if present.) in P. chinensis, but for P. merguiensis and P. penicillatus, there are prominent dorso-median spine on the posterior margin of all abdominal somi七e.

From the first mysis, P. chinensis different from P. merguiensis and P. penicillatus in having 9 long plumose setae on the exopod of 1-3 pereiopods, for 〆

the latter two species, there are only 8; In the second and七hirdmysis,七hereare 9 long plumose seta on the exopods of七hirdmaxilliped and 1-5 pereiopods in P. chinensis and only 8 (or sometimes 7 on the exopod of the third maxilliped in second mysis in P. merguiensis and P. penicillatus. Additionally, P. chinensis has 2 (mostly) or 1 dorsal teeth on the rostrum in third mysis and 2-3 in first postlarva respec七ively. P. penicillatus and P. merguiensis have only in third mysis and first postlarval.

The present au七hors have found that P. chinensis is characterized by having a pair of unifurcated supra-orbital spines in the second zoea, which has never been repor七edin other species of七hisgenus. It is also suggested to use the number of plumose setae on the exopod of pereiopods in mysis stages as a diagnostic

A NUMERICAL WAVE PREDICTION MODEL FOR THE JAPAN SEA

RYANG PYONG

Oceanographic Research Institute of Korea West Sea, D.P.R. Korea

This work is concerned to a opera七ionalnumerical wave predic七ionmodel for七heJapan Sea. This model of Dp type is based on七hewave spectral energy-balance equa七ion. The model was tested under some wind conditions, and is in 七heapplication a七 theCentral Weather forecasting Center of HMS.

This model is similar to the Isozaki's (1972) model in its form, bu七 linearand exponential growth coefficien七s A and B are no七 same as tha七 of Inoue (1967). That is, we use the coefficients of Baどnettmodel. (Barne七七, 1968)

This model is Dp七ypemodel, in which each wave cell or componen七 propaga七esat its appropriate group velocity along its own ray pa七h.

For the purpose of experiments with the model, calcula七ion of wave fields was carried out over the grid area of the Japan sea. In order to es七ima七e the behaviour of 七he model presen七ed above the significan七 wave heigh七s,H, and periods a七 each points over the grid area were calcula七ed under various wind conditions.

Although these wind conditions are artificial, but such wind fields may be considered as possible one over oceans and seas, and with such ar七ificialwind conditions we can estimate the behaviour of ouど mode1. Then we are also able to compare to a we11 known results or diagrams on wave charac七eris七ics.

For七hesepurpose, we can use the Manua1 Wave-Forecasting Diagram. (WMO, 1988: Guide to Wave Analysis and Forecasting, WMO-No. 3-30) In the growth stages七hemodel cuどves agree reasonably well with these those of the diagram, Also, a another comparison was presented in this paper.

In addi七ionto these, all the results from various wind conditions are shown七hatthe model gives very satisfactory results over the Japan sea.

This wave model started to run from oc七ober1990, using wind da七afどomoutpu七 ofNumerical Wea七herForecast Model of the Central Weather Forecasting Institute of HMS. The surface winds over 七he sea are estimated by a model for calcula七ingsurface winds fどompressure fie1d, surface air and sea surface七emperature,which was proposed by Cardon (1969)・

Systematic verification of this model are made operationally using visual wave observation from ships. For example, F ig. 3 is a wave forecas七 field for

、 09-31-maどchof 1991.

Wave modelling is a technique for objective wave analysis and forecasting, and must be based on good understanding of wave phenomena and analysing of reliable wave observa七ionsor measurements. In the next steps, we would like to improve our model by considering wave-wave in七eractionand coastal七ransform.

TBE EFFECTS OF MOUHTAIH MASSIF AHD SEA ON TBE FORMATIOH OF TBE OKBOTSK BIGB

KANG BOM JIN

OceanogどaphicResearch Insti七uteof七heKorea East Sea, D.P.R. Korea

Korea is a peninsula located a七 eastside of Eurasian con七inen七. 50 when we study abou七 atmosphericphenomena and climate character of Korea, we have to consider 七heinfluence of the sea on七hemas well as of the continent.

Okhotsk High that occurs on the Okhotsk Sea in summer is also formed by bo七heffects of sea and 1and it exists with rather 10ng duration.

As Okhotsk High is formed and it ex七endsto the north par七 ofKorea East Sea (Japanese Sea) by七hecold sea wa七er,cold and we七 marineair mass is七ranspor七edthere along the south edge of the High and thus, co01 summer damage occurs in noどthpart of the east coas七alどegionof Korea.

To realize mechanism of formation of Okhotsk High has an important significance in undeどstanding basic process of cool summer damage and otheど climaticproperties of Korea.

工n order to realize the mechanism, we have some statistical consideration and numerical experiments.

With the view of carrying out the numerical experiment on a microcomputer, a 3 layers spec七どalprimitive equation model in七herectangulaど domainis developed, which is七houghsimple enough for practical applica七ion, yet has capabili七Yof responding effectively to the external thermal and dynamical forcing due to land and sea.

Theどesultsthat we get from sta七isticalconsideration and numerical experiments are as follows:

i) The atmospheric planetary wavesoccur by dynamical effec七 of Tibe七anpla七eau,

Rockies and another massif. As the result, the ridge which reaches to high level is formed around Okhotsk Sea in summer.

The loca七ionof Jet stream and the in七ensityof westerly are change seasonaly, which makes the dynamical effec七 ofthe massif vary. Therefore Okho七skHigh has seasonal charac七er,

ii) One of七he important character of Okhotsk Sea is tha七 seawater is colder than ano七hersea at七hesame latitude.

Thus this cold water affects七o formation of Okhotsk High as thermal sink. The low level high is formed by this effec七, but the effect can ・七 make high level one.

But if Low level high due to thermal sink is connected with upper ridge or high 七hatoccurs by dynamical effect which have been sta七edabove,七alland lasting Okhotsk High is formed.
