attribute NC_GLOBAL acquisition_description String #### Methodology:

Field work was done on four cruises conducted during the austral fall and
winter. Cruises 1 (2001) and 3 (2002) were aboard the Antarctic Research
Support Vessel (A.R.S.V.) Laurence M. Gould from April to June; cruises 2
(2001) and 4 (2002) were aboard the Research Vessel Ice Breaker (R.V.I.B.)
Nathaniel B. Palmer from July to September.

Samples were collected with a 10m2 MOCNESS (MOC-10) outfitted with six 3mm
mesh nets. The initial net fished obliquely to depth with each subsequent net
fishing a discrete depth layer upward to the surface. At stations with
depths>1000 m, layers sampled were 0-1000, 1000-500, 500-200, 200-100, 100-50,
and 50-0 m. At stations with depths >500 m, layers sampled were 0-500,
500-300, 300-200, 200-100, 100-50, and 50-0 m. At stations with depths <500 m,
sample layers were modified to provide optimal coverage of the water column
with the five discrete-depth nets.

A total of 62 MOC-10 trawls were done, 22 each in the fall of 2001 and 2002,
and 9 each in the winter of 2001 and 2002 (Table 1). Trawls were conducted at
various times throughout the day. In the fall, 37 trawls occurred at night
(18:00-06:00 h), 1 in daylight, and 6 at dusk. In the winter, seven trawls
occurred at night, seven in daylight, and four at twilight. Towing speed for
all tows was 1.5-2.2 knots. Tows in pack ice were conducted in leads created
by the ship's wake with the A-frame in to minimize the chance of hooking the
wire on ice floes. When ice conditions dictated, the ship first traversed a
trawling transect prior to deployment and then backtracked over the same
course through the created lead to insure that adequate speed could be
maintained for the duration of the tow.

attribute NC_GLOBAL instruments_0_description String The Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) is based on the Tucker Trawl principle (Tucker, 1951). The MOCNESS-10 (with 10 m^2 nets) carries 6 nets of 3.0-mm circular mesh which are opened and closed sequentially by commands through conducting cable from the surface (Wiebe et al., 1976). In this system, "the underwater unit sends a data frame, comprising temperature, depth, conductivity, net-frame angle, flow count, time, number of open net, and net opening/closing, to the deck unit in a compressed hexadecimal format every 2 seconds and from the deck unit to a microcomputer every 4 seconds" (Wiebe et al., 1985).

attribute NC_GLOBAL projects_0_description String The fundamental objectives of United States Global Ocean Ecosystems Dynamics (U.S. GLOBEC) Program are dependent upon the cooperation of scientists from several disciplines. Physicists, biologists, and chemists must make use of data collected during U.S. GLOBEC field programs to further our understanding of the interplay of physics, biology, and chemistry. Our objectives require quantitative analysis of interdisciplinary data sets and, therefore, data must be exchanged between researchers. To extract the full scientific value, data must be made available to the scientific community on a timely basis.
