String acquisition_description
"The sediment trap array was deployed at the beginning and recovered at the end
of each experimental cycle.The array consisted of two VERTEX-style particle
interceptor tube (PIT) crosspieces (Knauer et al. 1979, Stukel et al. 2013),
deployed at what investigators initially thought to be the base of the
euphotic zone (100 m on cycle 1, 90 m on other cycles) and 150 m. Each
crosspiece held 8-12 cylindrical trap tubes, with an inner diameter of 70 mm
and an 8:1 aspect ratio. Each tube also contained a baffle constructed of 14
smaller tubes that had been tapered at the top to ensure that all particles
settling within the inner diameter of the outer tube would sink into the trap.
Tubes were deployed with 2 L of a slurry comprised of 0.1-um filtered
seawater, amended with an additional 50 g L-1 NaCl, and formalin (1% final
concentration).
Upon recovery, the height of the interface between trap slurry and overlying
water was immediately determined and the overlying water was gently removed
with a peristaltic pump. Samples were then gravity filtered through a 200-um
mesh Nitex filter and the contents of the filter were sorted under a
dissecting microscope to remove mesozooplankton that were believed to have
swam into the trap. The remainder of the >200-um particles were then re-
combined with the <200-um. Individual tubes were split using a Fulsom split to
allow replicate measurements of multiple different components of the sinking
including organic C (Corg), N, and pigments (reported in Stukel et al. 2013).
Samples for pigments were filtered through GF/F filters and extracted in 90%
acetone for greater than 24 hours. Chlorophyll a and phaeopigments were then
determined on a Turner Designs model 10 fluorometer (Strickland and Parsons,
1972). Samples for C and N were filtered through a GF/F filter and frozen at
-80C. On land, filters were cut in half and acidified with HCl for 24 hours.
They were then analyzed for C and N on the CHN analyzer at the SIO Analytical
Facility.

String instruments_0_description "Floating sediment traps are specially designed sampling devices deployed to float in the water column (as opposed to being secured to a mooring at a fixed depth) for periods of time to collect particles from the water column that are falling toward the sea floor. In general a sediment trap has a container at the bottom to collect the sample and a broad funnel-shaped opening at the top with baffles to keep out very large objects and help prevent the funnel from clogging. The 'Sediment Trap -Floating' designation is used for a floating type of sediment trap about which no other design details are known.";

"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.
