"Mesozooplankton net collections
Mesozooplankton sampling was conducted using a standard 1-m2 ring net with
202-um Nitex mesh, towed obliquely for 20 minutes at a ship speed of 1-2 kts.
A General Oceanics flowmeter was attached across the net mouth to record
volume filtered, and a Vemco depth meter was fastened to the net frame to
record tow depth and duration. The target depth of tows was 150 m. Once on
deck, the net was washed down with seawater and the contents of the cod end
placed in a bucket with carbonated water to prevent gut evacuation. Separate
splits (each of typically 1/8th of the sample) were used for biomass and gut-
fluorescence determinations. Each of these subsample splits was wet sieved
into five size classes of 0.2-0.5, 0.5-1, 1-2, 2-5, and >5 mm.
Biomass estimates
Each size-fractioned sample for biomass was concentrated onto a pre-weighed
202-um Nitex screen, rinsed with ammonium formate to remove interstitial sea
salt, placed in Petri dishes and frozen at -80\\u00b0C for later analysis on
shore. The frozen samples were thawed, blotted on paper to remove excess water
and weighed (wet weight) to 0.01 mg at room temperature on an analytical
microbalance (Denver Instrument). Immediately afterwards, samples were dried
in an oven at 60\\u00b0C for at least 24 h, and weighed on the same instrument
to obtain dry weight estimates. After subtracting the initial weight of the
Nitex screen, the wet weight (WW) and dry weight (DW) of each size fraction
were obtained by the appropriate multiplication factors for previous sub-
sampling. Areal biomass estimates (i.e., g m-2) were computed from total net
sample estimates by multiplying by the factor, D/vol, which reflects the water
depth (D, m) and volume filtered (vol, m3).";

"Research was aimed at improved understanding of plankton dynamics, carbon and nutrient fluxes, and potential trace element limitation in the Costa Rica Dome region of the eastern tropical Pacific. The specific science objectives of the 2010 R/V Melville cruise (MV1008) were:
1) to assess grazing and trace metal/nutrient controls on primary production and phytoplankton standing stocks;
2) to quantify carbon and elemental fluxes and export rates from the euphotic zone; and
3) to measure microbial population, processes, stable isotope abundances associated with the OMZ and nitrite maxima.
Additional information about MV1008 can be found in the cruise report (PDF).
NOTE: The original proposal and award abstract are not relevant. The project was originally funded by NSF as experimental tests of phytoplankton controls in the Arabian Sea. Piracy concerns in the region led to the cancellation of the research cruise in 2009, and a Change of Scope request was approved to focus the project on related issues in the Costa Rica Dome (CRD).
Though this project is not formally affiliated with any large program, it aligns with IMBER's emphasis on community ecology and biogeochemistry, and the OCB focus on carbon-based measurements of production, grazing and export processes.";

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.
