String acquisition_description
"Seawater was collected with Niskin bottles at several depths and filtered
through both GFF filters and 2 \\u00b5m pore glass fibre filters for analysis
of Chlorophyll a and total phaeopigment. Immediately after water samples were
filtered, filter pads were transferred into 6 ml of 90% acetone and the
pigment was extracted in a dark refrigerator for 24 hours. Filter pads were
removed and the test tubes centrifuged just prior to reading the fluorescence.
Following the initial fluorescence reading, samples were acidified with ~0.2ml
of HCl and reread. The fluorometer was calibrated using a spectrophotometer
during each cruise using standard Chl-a derived from spinach. Chlorophyll-a
and phaeopigments were calculated from standard equations (Strickland and
Parsons 1972).";

String projects_0_description "Salps are holoplanktonic grazers that have a life history, feeding biology and population dynamic strikingly different from copepods or other crustacean zooplankton. They can occur in very dense populations that cover large areas, and these blooms have been shown to have major impacts due to grazing and production of fast?sinking fecal pellets. However the conditions supporting bloom formation, and the energetics, reproduction and behavior of the bloom?forming salps are still poorly understood. This study will focus on two species of salps that are global in their distribution and representative of two genera that commonly form large blooms. Salpa aspera regularly occurs during the summer in high concentrations in the slope waters of the Mid?Atlantic Bight, while Thalia democratica regularly forms dense populations during the winter spring in the Georgia Bight. The investigators will examine feeding, metabolism, growth, reproduction and population dynamics of these salps. They will use two independent modeling approaches, grounded in experimental and field data, to extend their observations to other time and space scales. interpret ouexperimental and modeling results will be interpreted within the context of the environmental conditions to which the salps are exposed. This integrated approach will provide the best basis for understanding how salp blooms form and persist. Results of this study will extend to other species that occur in high densities in many locations, allowing scientists to better evaluate the importance of salps in biogeochemical cycles and in structuring the pelagic environment.";

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.
