INTRODUCTION
Lower Cook Inlet is part of the estuarine system connecting Anchorage with
the Pacific Ocean. The area is of high interest to federal, state, industrial
and private groups since lease sale Cl was held during the fall of 1977. As
part of an overall environmental assessment, a marine geologic study was per
formed during the summer of 1976 (Fig. 1). Seismic reflection information was
collected on board the R/V SEA SOUNDER using single channel sparker, uniboom
and 3.5 kilohertz seismic profiling systems. In addition, side-scan records
were obtained and a bottom television unit deployed. Bottom sediments were
collected with a Van Veen grab sampler, modified by A. Souter (Scripps
Institution of Oceanography) and with a gravity corer (Bouma and Hampton, 1976;
Hampton and Bouma, 1976).
During the same time period Petty-Ray Geophysical Inc. conducted a seismic
survey for the U. S. Geological Survey, Conservation Division, in Anchorage,
Alaska. Part of their data are incorporated in this report.
Lower Cook Inlet is characterized by a rather smooth bottom and strong
tidal currents. The surfical sediments are sand to pebbly sand in the south,
becoming pebbly to the north (Bouma and Hampton, 1976). The high-velocity
currents have produced a variety of bedforms of different sizes and shapes
(Bouma et al. 1977a; Bouma, Hampton and Orlando, 1977b). Scanning electron
microscopy examinations of surface characteristics of quartz grains (Hampton
et al., 1978) provided information on movement characteristics of the sand
within and outside the field of bedforms.
This report contains information on four major bottom aspects of lower
Cook Inlet: bathymetry, distribution of bedforms, grain-size parameters of
bottom samples, and a map of Quaternary sediment thicknesses.

BATHYMETRY
Bathymetric information obtained during the 1976 R/V SEA SOUNDER cruise
was combined with the bathymetric results collected by Petty-Ray Geophysical;
and additional information from the U. S. Coast and Geodetic Survey Boatsheets.
All information was converted to the metric system and contours drawn at 5 m
intervals. Petty-Ray Geophysical had all their measurements tidally corrected.
Although the overall bathymetry of lower Cook Inlet is rather smooth, a
number of characteristic bottom morphologic features are worth mentioning (Fig. 2,
Enclosure 1). South and south southwest of Kalgin Island (island cut off by
upper boundary of Fig. 2), down to Tuxedni Bay, the bathymetry shows some minor
depressions. The eastern half of the northern part of lower Cook Inlet is
rather smooth and slopes to the west.
The central area of lower Cook Inlet between Tuxedni Bay and a line between
Kenai Peninsula and Augustine Island is rather smooth with a major depression
running approximately north-south through its center. The eastern half con
tains a few minor depressions that line up in a direction parallel to the major
depression without revealing the existence of a major linear depression. Another
channelized depression exists along the northwestern side of Kenai Peninsula
forming the major connection between Cook Inlet and Kachemak Bay. This central
part of lower Cook Inlet is also the major area of bedforms (Fig. 3).
Between the central and southern part of lower Cook Inlet a significant
ramp occurs, starting at about 70 m water depth and dropping to about 115 m. The
ramp is very pronounced on the western side off Cape Douglas. The ramp between
the central and southern parts of lower Cook Inlet has a northerly indentation
that more or less lines up with the major central depression. This combined
system may represent the paleo channel of Cook Inlet. The central area of
southern lower Cook Inlet is a rather uniformly sloping area.
Connections between Cook Inlet and the Pacific Ocean via the Kennedy and
Stevenson Entrances reveal complicated bathymetry with many local highs and
lows of tectonic origin. A set of highs are present south of the Chugach Islands,
bounded by a depression with local deeps on its southern side. It is likely
that the major tidal waters flow through this depression and then split into
a northern component along Kenai Peninsula into Kachemak Bay and through the
eastern half of lower Cook Inlet, while another part of the incoming water
deflects off the ramp and turns in a counter clockwise direction toward Shelikof
Strait. The bathymetry of Stevenson Entrance is less complicated but still
reveals tectonic influences.
Insufficient data are available on the currents and tidal flows to fully
establish the importance of the bathymetry on circulation in the inlet. A
program by NOAA/PMEL during FY78 hopefully will shed light on these questions.
Published information on surface currents via driftbottle studies is discussed
by Burbank (1977) but lack of current-meter data prevents further discussion.

DISTRIBUTION OF BEDFORMS
A combination of Petty-Ray Geophysical and R/V SEA SOUNDER seismic high-
resolution data and side-scan sonar was used to construct a distribution map
of bedforms. Figure 3 shows that only the central part of lower Cook Inlet
contains significant bedforms. This may be accidental due to insufficient
trackline coverage in the surrounding areas. These latter areas do not contc
any bedform fields of significant extent, but minor fields may be present.
A major type of bedforms are sand waves that occur in three important
size classes (Bouma et al., 1977a): 1) wave length less than 8-15 m and wav<
heights not exceeding 2 meters, 2) wave lengths ranging from 50-150 m with
wave heights ranging from 3-5 m, and 3) wave lengths ranging from 400-1000 m
with wave heights between 5-10 m. Sand waves in lower Cook Inlet normally a
strongly asymmetric rippled bodies of sand with relatively smooth flanks and
straight to slightly sinuous crests.
Dunes can occur in similar medium and large size classes. These bedfor
differ from sand waves in that their shapes are more irregular, their crests
very sinuous and discontinous, and their wave length/wave height ratio is
smaller.
Sand ridges are only known from the southeast corner of the bedform fie
These are larger asymmetric sand bodies with wave lengths ranging 800-1000 it
and wave heights from 8-10 m. Their crests, in contrast to sand waves and
dunes, are parallel to the main current direction. Medium sand waves occur
the flanks of sand ridges. However, the crests of the medium-sized waves ai
not parallel but oblique to the crest and sand ridge, presumably due to forv
upward movement under the action of helical currents (Bouma et al., 1977a; I
Hampton and Orlando, 1977b).
Another important type of bedform is the sand ribbon, a narrow, thin
body of sand, oriented parallel to the main current. Small sand waves, with
crests perpendicular to the sand ribbon, normally cover the surface of the ribbon.
The largest sand waves are concentrated in a number of fields in the
southern half of the centralpart of lower Cook Inlet. They are always surrounded
by medium or small-sized sand waves. A number of fields of large sand waves are
located in the major depression.
Immediately north of the ramp is a smooth area of sea floor that does not
contain bedforms large enough to be detected on high resolution seismic profiles
or side-scan sonar records. This "smooth" area is bounded on three sides by
large sand waves.
Sand ribbons can only be detected on high quality side-scan sonar records,
which may be reason that only a limited number are displayed in figure 3. They
only occur where the sand cover is thin or non-existent.
No public data are available to compare the distribution and individual
characteristics of the sand waves, especially the larger ones. Although
bottom television observations indicate grain motion up to 30 cm/sec over the
crests of large sand waves and 1-5 cm/sec in their troughs, and bottom currents
may be as high as 1 knot (50 cm/sec), no information is available to migration
of the large sand bodies. Scanning electronic microscopy examination on quartz
grain surface textures showed that grains are not widely dispersed into and
out of the large area of bedforms (Hampton and others, 1978).
GRAIN SIZE PARAMETERS
Introduction
Grain size analyses were run in the laboratory using Rapid Sediment
Analyzers. This technique is based on fall velocity through a high column of
water. The data were next punch carded and fed to the computer under the
heading sieve. The program provides several types of data such as cummulative
percentages, statistical parameters and graphic presentations.
This section includes a discussion of the parameters provided, the graphic
presentations, and a brief discussion about the findings and preliminary
conclusions drawn from this aspect of the study.
Statistical Parameters
Quantitative evaluation and comparison of grain size distributions of
sediment samples is possible through the use of statistical parameters. The
two methods of determining the size distribution of a sand-size sample are
sieving and settling tubes. Both systems give size data in millimeters and/or
phi (cj>) units, though the sieving method measures the physical size of particles,
whereas the settling tube measures the settling velocities of the grains through
water, which are then compared to the settling velocities of quartz spheres of
known size. In other words, a small heavy mineral and a large light mineral
may be hydraulic equivalents and fall into the same size range as measured by
a settling tube, but the same two grains would be measured as being of quite
different diameter in a sieve analysis.
10
Graphic Representation
The data obtained in a grain size analysis may be plotted in several
ways. All methods use grain size as the abscissa and some measure of percent
age frequency as the ordinate. It is usual to plot grain size in phi units,
which relate logarithmically to millimeters 25: -log d = <j>, where d is grain
diameter, and <j> i s size in <j> -units.
The histogram is a bar graph, where the height of each bar represents the
weight percent of grains in a particular size class. A frequency curve is a
smooth curve through the midpoints of the bar tops. These types of plots are
only pictorial representations, statistical parameters cannot be determined
from them.
The cumulative curve is plotted by adding percentages in succeeding size
grades and drawing a smooth curve through the points. On arithmetic ordinate
paper the curve normally is S-shaped.
From the size analysis and its cumulative curve obtained through sieving
or settling tube methods, statistical parameters can be calculated that
quantitatively describe features of the sediment. The parameters and certain
combinations of parameters can be compared and can give an indication of
sedimentary environments of deposition.
Parameters
The parameters calculated in this study include:
1) "mode": the most frequently occurring grain size or sizes. It
corresponds to the inflection points in the cumulative curve or the highest
points on the frequency curve. The mode is useful in transport studies,
especially when two or more sources are contributing sediment;
11
2) "median": half the particles by weight are larger than the median, and
half are finer. It is easily found on the cumulative curve, it corresponds to
the 50% mark;
3) "mean" (M ) : the average grain size. Several formulas can be used in z
calculating the mean. The most inclusive graphically derived is that given
by Folk (1968) :
M = ($16+$50 +$84)/3 (1)2
where 4)16, $50, $84 represent the size at 16, 50, and 84 percent of the sample
by weight. Folk's formula is superior to that of Inman (1952) which is based on
only two values. The Trask (1950) mean size is also included in our computer
printout (App. I) although few people use it anymore.
4) "sorting": several methods exist for graphically determining the sorting,
or uniformity, of sediments. In general, the best measures of sorting are those
that encompass the greatest part of the size distribution. Folk (1968) intro
duced the "inclusive graphic standard deviation" (0 ) . It is considered to be
the best graphically derived method of measuring the grain size variation in a
sample. It is calculated using the formula:
_ * 4 6.6
where $84, (f>16, $95, $5 represent the phi values at the 84, 16, 95, and 5 percent
markes on the cumulative curve. A verbal classification scale for sorting was
present by Folk (1968): a <0.35 , very well sorted; 0.35-0.50$ , well sorted;
0.50-0.71$ , moderately well sorted; 0.71-1.0$, moderately sorted; 1.0-2.0$
poorly sorted; 2.0-4.0$, very poorly sorted; >4.0$ , extremely poorly sorted.
Folk's method includes more of the curve than the measure introduced by Inman
(1952) where sorting (a_) = ($84 -$16) /2. Trask 's (1950) sorting coefficientG
(SQ) is used only with millimeter values and only includes the middle 50% of
the curve .
12
5) "skewness": cumulative curves for sediment-size distributions may be
the same in average size and sorting though they may be quite different in their
degree of symmetry. Measures of skewness determine the degree to which a curve
approaches symmetry. The most commonly used measure of skewness is Folk's
"inclusive graphic skewness" (1968) , determined by the formula:
= + $84 - 2050 $5 + $95 - 2$50 , 3) 1 2 ($84 - $16) + 2 ($95 - $5)
This formula is preferred as it includes the skewness of the "tails" of the
curve as well as the central portion. Other methods for determining skewness,
notably those of Inman (1952) and Trask (1950) do not measure the tails of the
curve and are of less value than Folk's (1968) method.
Symmetrical curves have a skewness equal to 0.00; those with a large^
proportion of fine material are positively skewed, those with a large proportion
of coarse material are negatively skewed. A verbal classification for skewness
suggested by Folk (1968) includes Sk from -1.00 to -0.30: strongly fine skewed;
+.30 to +0.10: fine skewed; +0.10 to -0.10: near symmetrical; -0.10 to -0.30:
coarse skewed; and -0.30 to -1.00: strongly coarse skewed.
6) "Kurtosis": a measure of "peakedness" in a curve. A normal Gaussian
distribution has a kurtosis of 1.00: it is a curve in which the sorting in the
tails equals the sorting in the central portion. If a curve is better sorted
in the central part of the curve than in the tails, it is said to be excessively
peaked, or leptokurtic; if it is better sorted in the tails than in the central
portion, it is flat-peaked or platykurtic. Folk's (1968) formula for kurtosis
is given by__ $95 - $5
g 2.44($75 - $25) - (4)
For normal curves K =1.00, leptokurtic curves have K >1.00, platykurtic<? y
curves have K <1.00. g
13
Method of Moments
All the above statistical parameters can be calculated using the method
of moments. This method gives a somewhat truer picture of the sediment
characteristics, but when calculated by hand, it is a tedious process. The
computer program used in this study performs all the necessary calculations,
greatly simplifying the determination. The first moment measure corresponds
to the mean, the second to the standard deviation, the third to the skewness,
and the fourth to the kurtosis.
Cook Inlet Samples
Surficial sediment samples from lower Cook Inlet were taken in June and
July of 1976 aboard the R/V Sea Sounder. A modified van Veen grab sample,
capable of taking an undisturbed surface sample of 40x60x30 cm was used to
collect the unconsolidated sediments. The top two centimeters of each grab
sample were used for grain size analyses.
Samples were taken from the bedform fields that occupy much of central
lower Cook Inlet (Fig. 4). Water depths range from 40 to 100 m, averaging
about 70 m. The area is one of very strong currents. Surface water velocities
of 3-5 knots (150-250 cm/sec) are common during flood and ebb tides.
Grain size analyses of the samples show several gross trends. The mean
grain size decreases more or less uniformly from north to south in the samples
analyzed (Fig. 5). Concomitant with the decrease in grain size from north
to south is an increase in the degree of sorting of the samples as indicated by
the decrease in standard deviation (Figs. 6 and 7).
The apparent decrease in grain size from north to south in lower Cook Inlet
may be due to one or several of the following: 1) it may simply be an artifact
of sampling; not enough samples were taken to have a high confidence level in

the results, 2) it may reflect an original variation in mean grain size from
north to south in lower Cook Inlet, 3) or it may be due to progressive sorting
of the sediments by currents.
A systematic variation in grain size after the last glacial retreat from
Cook Inlet is unlikely as glaciers are very poor sorting agents; glacial deposits
are generally extremely poorly sorted mixtures of all size grades up to very
large boulders. A more probably explanation is that the decrease in mean size
and increase in sorting from north to south is due to progressive sorting by
transport and winnowing.
Several lines of evidence support this interpretation. First, the majority
of bedforms are consistently orientated with their steep faces toward the south
indicating net transport in that direction (Bouma and Hampton, 1976; Bouma
et al., 1977a) . In addition, studies of quartz grain micro-surface textures in
dicate dominantly mechanical abrasion typical of aqueous transport in the
bedform fields (Hampton and et al,, 1978). Quartz surface microtextures
commonly associated with glacial action are also present in lower Cook Inlet,
though, for the most part, these occur in an unmodified state rarely in the
bedform fields (Hampton et al., 1978). Most original glacial micro-
textures present in the bedform fields have been overprinted with subaqueous
transport features, indicating sufficient transport to subdue the original
textures.
Inspection of the skewness and kurtosis reveals little information, primarily
because so few samples are represented. The range in skewness is -0.5 to 0.4;
most samples, however/ are very close to symmetrical (0.0) in their size
distribution (Fig. 8). Kurtosis shows a greater variation, from 0.28 to 1.96.
There appears to be a slight tendency for the sediments to become negatively

GENERALIZED ISOPACH MAP OF QUATERNARY SEDIMENTS
Sparker records from the 1976 cruise of the R/V SEA SOUNDER were used to
make thickness measurements at 15 minute shot point positions of the uppermost
sedimentary unit in lower Cook Inlet (Fig. 10). From these data, a generalized
isopach map was constructed (Fig. 11).
Thicknesses were measured from the sea floor to an angular unconformity
that shows distinctly on most of the records. Several thickness measurements
were uncertain or indeterminable because of poor-quality records, shallow
penetration, or the occurrence of the unconformity within the bubble pulse or
a sea-bottom multiple. Where readings of "zero" thickness were recorded, the
unconformity apparently rises to the sea floor and controls the sea floor
geometry. Variations in the thickness of Quaternary sediments throughout lower
Cook Inlet reflect a combination of variations in the elevations of the un
conformity surface and of the sea floor.
In making the following maps, the assumption was made that the deformed
rocks below the unconformity are of Tertiary age, judging from the on-land
geology, and that the generally flat-lying sediments above the unconformity
are primary and reworked glacially derived sediments deposited during Pleistocene-
Holocene upper Tertiary age.
The thickness measurements were contoured only generally. Many thickness
variations greater than one contour interval were ignored because they involve
only one or two measurements. Consequently, many small basins and highs exist
that do not show on the map. The areas south of Augustine Island and
surrounding the Barren Islands are especially complex, and major portions of
these areas were not contoured.

APPENDIX I
Computer printout of sampling station data, grain size values, sediment
parameters and graphic presentations of the surficial samples analyzed from
lower Cook Inlet.
The computer printout shown in Appendix I gives all the pertinent data regarding
the size alalyses of the sand samples from lower Cook Inlet. Each sample has
five pages of printout; the top of each page gives the cruise identification,
sample number and type (in all cases Soutar van Veen grabs) and sample length,
which is not applicable in the case of grab samples. The first page gives
the method of analysis, total sample weight, and particle size distribution in
mm. and phi (cj>) units, and the size class ratios. Because all samples were
entirely composed of sand-size material, the ratios are in all cases non
existent. The second page gives the interpolated values used in calculating
graphical statistics, which include Folk and Ward's (1968), Inman's (1952), and
Trask's (1950) median, mean, sorting, skewness and kurtosis values. Moment
