National Marine Fisheries Service, Special Scientific Report—Fisheries
The major responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographicdistribution of fisherv- resources, to understand and predict fluctuations in thequantity and distribution of these resources, and to establish levels
for optimum use of the resources. NMFS is also charged with the development and implementation of policies for managing national fishinggrounds, development and enforcement of domestic fisheries regulations, sur\eillance of foreign fishing off United States coastal waters, and thedevelopment and enforcement of international fishery agreements and policies. NMFSalsoassists the fishing industry through marketing service
and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics onvarious phases of the industry.
The Special Scientific Report— Fisheries series was established in 1949. The series carries reports on scientific investigations that documentlong-term continuing programs of NMFS. or intensive scientific reports on studies of restricted scope. The reports may deal with applied fishery
problems. The series is also used as a medium for the publication of bibliographies of a specialized scientific nature.

ABSTRACT
Midwater invertebrates were collected in the southeastern Chukchi Sea. A 1.8-m Isaacs-Kidd
midwater trawl was used at 20 stations to collect 81 semiquantitative samples; a :!-m otter trawl was
used at one station to collect two qualitative samples. Data tables list the species collected and their
numbers, size range, and displacement volumes for the midwater trawl stations and a species list only
for the otter trawl station. One hundred three species of invertebrates were identified from the mid-
water trawl samples, and ,33 species were identified from the otter trawl samples. Amphipods were the
most diverse group (40 species) and decapod shrimps the next most diverse (14 species). Numbers of
species in a sample varied from 4 to 40 (mean 17). After removal of jellyfishes, the most important con-
tributors in numbers and volume to the catches were euphausiids and mysids.
INTRODUCTION
The Western Beaufort Sea Ecological Cruises (WEB-SEC) were a sequence of oceanographic cruises spon-
sored by the U.S. Coast Guard to assess the Alaskan arc-
tic marine environment and biota before major indus-
trial development. The Coast Guard enlisted the efforts
of federal, state and university research groups for the
program, and the National Marine Fisheries Service con-
tributed to the first three cruises with studies of
zooplankton, midwater invertebrates, and fishes.
The intent of the first cruise, WEBSEC-70, which took
place during September and October 1970, was to ex-
amine the arctic coast from Barrow eastward to Barter
Island. Extremely heavy ice conditions in mid-Septem-
ber 1970 prevented the Icebreaker Glacier from working
in the Beaufort Sea; therefore, an alternative area, the
southeastern Chukchi Sea between Point Lay and Cape
Lisburne (Fig. 1) was surveyed between 25 September
and 17 October. Preliminary results of physical,
chemical, geological, and biological investigations for
WEBSEC-70 were reported by Ingham et al. (1972); and
reports were later published by Quast (1974) and Wing
(1974).
This report presents data on the invertebrates taken in
midwater trawls made to collect fishes from 25 Septem-
ber to 17 October 1970. The data are presented in tabular
form and are not interpreted, although some apparent
sampling anomalies are discussed. The tables provide a
list of species found, numbers of individuals taken, and
linear size range and displacement volume of the

specimens of each species. These data are the first
attempts to quantitatively assess macroplanktonic and
niicronektonic invertebrates in the southeastern Chuk-
chi Sea.
METHODS
A 1.8-m Isaacs-Kidd midwater trawl was used to
sample at 20 stations for a total of 81 tows (Fig. 1, Ap-
pendix Table 1). The trawl had a forward section of 38-
mm bar mesh, a rear section of 6-mm bar mesh, and a
cod end of 3-mm bar mesh. Cross-sectional areas were
calculated to be 2.87 m' at the mouth, 1.55 m' at the
beginning of the 6-mm mesh, and 0.13 m- at the begin-
ning of the 3-mm mesh. The depth of tow was recorded
by a bathykymograph attached to the bottom of the
depressor. Tows were standardized for a length of 3.7 kmat an estimated vessel speed of 4 knots. At least four tows
were made at each of the 20 stations, two on one bearing
and two on the reciprocal bearing. Trawling was general-
ly done at night in areas relatively free of ice. The choice
of sampling depths was dependent on water depths and
on whether or not the samples were intended to be
replicates or were to examine depth distributions (Quast
1974).
At one station (No. 8—Fig. 1) two trawls were made
with a 3-m, 38-mm mesh otter trawl (shrimp try net) to
collect bottom fishes and invertebrates.
Large scyphomedusans and most hydromedusans
taken in the trawls were discarded in the field after the
sizes and numbers of each species of scyphomedusan and
the volumes of hydromedusans had been recorded. The
other invertebrates were preserved in 5'"c Formalin.
In preparation for examining the invertebrates in the
laboratory, formalin was washed from the samples and
