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).";

"The original title of this project from the NSF award is: Collaborative Research: Impacts of Eddies and Mixing on Plankton Community Structure and Biogeochemical Cycling in the Sargasso Sea\".
Prior results have documented eddy-driven transport of nutrients into the euphotic zone and the associated accumulation of chlorophyll. However, several key aspects of mesoscale upwelling events remain unresolved by the extant database, including: (1) phytoplankton physiological response, (2) changes in community structure, (3) impact on export out of the euphotic zone, (4) rates of mixing between the surface mixed layer and the base of the euphotic zone, and (5) implications for biogeochemistry and differential cycling of carbon and associated bioactive elements. This leads to the following hypotheses concerning the complex, non-linear biological regulation of elemental cycling in the ocean:
H1: Eddy-induced upwelling, in combination with diapycnal mixing in the upper ocean, introduces new nutrients into the euphotic zone.
H2: The increase in inorganic nutrients stimulates a physiological response within the phytoplankton community.
H3: Differing physiological responses of the various species bring about a shift in community structure.
H4: Changes in community structure lead to increases in export from, and changes in biogeochemical cycling within, the upper ocean.

String summary
"Zooplankton biomass estimates were determined from 1 m^2, 150 micron mesh
MOCNESS (Multiple Opening/Closing Net and Environmental Sensing System) tows.
The following discrete depth intervals were sampled on the upcast: 0-50,
50-100, 100-150, 150-200, 200-300, 300-400, 400-500, 500-600, and 600-700 m.
Generally paired tows during the day (9:30-15:00 local time) and night
(21:30-03:00) were performed at each station. A single tow generaly covered
5-15 km.\\u00a0 The nominal position (lat_n and lon_n) for each tow is the
position at the mid depth 200-300m sampling interval.\\u00a0 Table 1 ([pg 1362

NOTES/Goldthwait_Steinberg_2008_Table1.pdf\\\\)) of Goldthwait and Steinberg
(2008) is a sequential list of all MOCNESS mesozooplankton tows and includes
eddy identification number and location.
Each sample was size-fractionated using nested sieves of 0.15 mm, 0.5 mm, 1
mm, 2mm, and 5 mm mesh. Zooplankton in each size class were transferred onto
pre-weighed 0.15 mm nitex mesh filters and rinsed with deionized water.
Samples were then dried for 24 hours at 60 degrees C and weighed.

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
For details, see the tabledap Documentation.
