Daten verankerter Strömungsmesser von JASIN 1978

Zusammenfassung

Nach einer kurzen Darstellung der mittleren hydro­graphischen Verhältnisse aus dem inneren Meßgebiet von JASIN (59° N, 12° 30' W) werden Daten aus Verankerungen K1, K2 und K3 in Form von Vektor­zeitreihen, Zeitreihen der Komponenten als fortschrei­tende Vektordiagramme und in Häufigkeitsverteilun­gen dargestellt. K1 war eine Unterwasserverankerung mit 7 Aanderaa-Strömungsmessern in den oberen 1000 m. Bei K2 handelte es sich um eine doppelseitig verankerte formstabilisierte Oberflächenboje mit 6 VACM-Strömungsmessern und zusätzlichen Tem­peraturmeßgeräten im oberen Bereich der Sprung­schicht. Zwei vertikal parallel angeordnete Thermis­torketten im Tiefenbereich 2-82m bildeten das Herzstück der K3, welche ebenso wie K2 mit mete­orologischen Sensoren ausgestattet war. Die V eranke­rungen haben während mehrerer Wochen im Sommer 1978 Beobachtungswerte aufgezeichnet.

Summary

After a short presentation of mean hydrographic con­ditions at the Fixed Intensive Array of JASIN(59° N, 12° 30' W) data from moarings K1, K2 and K3 are given as stick plots and component time series, pro­gressive vector diagrammes, and frequency distribu­tions. K1 was a subsurface moaring with 7 Aanderaa current meters in the upper 1000 m. K2 was equipped with a spar buoy carrying 6 VACMs and some addi­tional temperature sensors in the upper thermocline. Two vertical and parallel thermistor chains in the depth range 2-82m were the main sensor arrays of K3, which , like K2, was also equipped with meteoro­logical sensors. Data from these moarings were ob­tained during several weeks in the summer of 1978.

1. Moorings

The international Joint Air-Sea Interaction Project JA­SIN 1978 included meteorological and oceanographic observations in the eastern North Atlantic west of Scotland . The main objectives of this programme and the field activities on research platforms from the Fed­eral Republic of Germany were summarized by SIED­LER & ZENK (1980) .

Three current meter moarings with self-recording instruments were deployed by the German participants in the Fixed Intensive Array (FIA). K1 was a single­point sub-surface moaring with 7 Aandera·a current meters and a small surface marker attached to the up­permost float. lt served studies of the vertical structure of the internal wave field in the water column below 100m. K2 included a spar buoy with 6 Vector Averag­ing Current Meters (V ACM) and 2 Aanderaa thermis­tor chains suspended below. The spar buoy was teth­ered to 2 surface moorings. It allowed observations of the current and temperature stratification in the upper 110 m needed for mixed layer structure and internal wave studies. K3 was a surface moaring with a H­shaped thermistor chain array with drogue attached, its purpose being the observation of temperature mi­crostructure variability in the mixed layer. Both K2 and K3 carried an Aanderaa meteorological package on a surface buoy. Although the moarings were de­ployed for individual projects, the obtained data Sup­plement each other to some extent and will therefore be presented tagether in this paper. Analysis of the in­dividual projects will be published separately at a later date.

Detailed figures of the 3 moarings were already · shown in SIEDLER & ZENK (1980) before, only simpli-

fied schematics including the IfM reference numbers are therefore presented in Fig. 1. The avai lab le data and mooring positions are summarized in Tables 1 and 2, including some general comments on data quality.

Particular effort was made to calibrate the thermis­tor chains of mooring K3 before the experiment. Groups of 16 sensors were calibrated at 7 tempera­tures, with reference to a quartz thermometer. The data points were fitted by a spline procedure. The res­olution obtained was ± 0.003 ° C. The data were re­corded on Sea Data tape casettes and transferred to computer tape after automatic reading.

Data processing at the Institut für Meereskunde of Aanderaa and VACM instruments followed the Stand­ard procedures like those described earlier by KÄSE et al. (1978).

2. D ata presentation

As an introduction to the mooring data in Figures 2-3 we present a selection of temperature, salinity and cr,-profiles, including their Standard deviations.

These CTD data originate from Multisonde and Bathysonde observations onboard R.V. "Meteor" and W.F.S. "Planet" . "Meteor" operated in the vicinity of our moorings wirhin the three JASIN phases : 8- 22 July (Phase 0), 23 July- 16 August (Phase 1) and 17 August - 16 September 1978 (Phase 2) . "Planet" was present during phase 2 only. For logistical details the reader may refer to SIEDLER & ZENK (1980) . Are­port on all stratification data has been prepared by KNüLL (1983). Current meter data from moorings are structured into three groups : K1 figures 4-14b, K2 figures 14c- 24, 26, 30 and K3 figures 25, 27 - 29, 31. After the presentation of stick plot diagrammes, pro­gressive vector diagrammes are shown. They are fol­lowed by grouped time series of current components and temperatures of the individual instruments and frequency distributions of selected temperature and current components.

Meteorological observations are summarized in Figures 30 and 31. A summary of the figure collection is given in Table 3.
