attribute NC_GLOBAL acquisition_description String Methods

Zooplankton abundance, vertical and horizontal distribution, and population
structure were assessed using a 1 m2 Multiple Opening and Closing Nets and
Environmental Sampling System (MOCNESS) with nine nets having 333 \u00b5m mesh
and environmental sensors of temperature, salinity and depth. The entire water
column was sampled on the downcast using net # 0, which was not analyzed. The
upper water column was typically sampled using nets 1 and 2 from 500 m to 200
m at 150 m depth intervals, nets 3 and 4 from 200 m to 100 m at 50 m depth
intervals, and nets 5 to 8 from 100 m to the surface at 25 m depth intervals.
Some tows were deployed down to 1000 m, and some tows were towed targeting
krill swarms at irregular depths. Approximate locations of process study
stations are shown in Fig. 1. More precise locations of the casts in Fig. 2.

Zooplankton samples were immediately preserved in 10% buffered formalin
solution. All the large organisms (>15 mm) in the sample were removed and
identified to taxa. The sample was then split to about 100 individuals of
euphausiids. All euphausiids in the split were identified to species and life
history stage and measured for length to the nearest 0.5 mm for larvae and to
the nearest 1.0 mm for juvenile and adults. Next the sample was split to about
100 individuals of copepods. Copepods were identified to species and life
history stage (female, male, copepodite V, or other copepodite). All other
zooplankton in the split were identified to taxa and counted. For the
Euchaetidae, we followed the designation of Park (1994) who ascribed the
Antarctic species to the genus Paraeuchaeta. This data object (\"krill\")
reports the abundance of each euphausiid species by life stage and size class.
The companion data object \"zooabund\" reports the counts of zooplankton per
subsample/split by taxa and life stage or size class.

Further methodology notes [05/07/08] from K. Daly:

My lab started the net sample analyses and we measured lengths of krill to
either the nearest 0.25 mm for larvae or to the nearest 0.5 mm for older
stages. As I recall, after we sent splits to the Russians to complete the
sample analyses, they decided it took too long to do individual measurements
and placed larvae into 0.5 mm length groups (3.0-3.4 mm) and the older stages
to the nearest 1.0mm. Jason took his original measurements to 0.25mm and
placed them in the 0.5 mm intervals used by the Russians. The 0.5 mm length
bins (3.0-3.4; 3.5-3.9;) should be the same for all net tows.

For the epibiont and comment information, the occurrence of epibionts was much
higher in 2001. This information is useful as a relative measure of percent
occurrence. I have seen these cilates before, but they are episodic.

The comments primarily provide information on indirect development. The larvae
were placed into a particular life history stage category, but they don't
always have the exact number of telson spines, etc., typical of that stage. I
reported this information in my 2004 DSR paper.

attribute NC_GLOBAL instruments_0_description String The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. The MOCNESS-1 carries nine 1-m2 nets usually of 335 micrometer mesh and is intended for use with the macrozooplankton. All nets are black to reduce contrast with the background. A motor/toggle release assembly is mounted on the top portion of the frame and stainless steel cables with swaged fittings are used to attach the net bar to the toggle release. A stepping motor in a pressure compensated case filled with oil turns the escapement crankshaft of the toggle release which sequentially releases the nets to an open then closed position on command from the surface. -- from the MOCNESS Operations Manual (1999 + 2003).

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.
