"* The Mark-5 profiler, has a higher sampling rate then the SeaBird SEACAT, was instrumented with an expanded suite of sensors and deployed almost exclusively at GLOBEC Standard stations.
* SeaBird SEACAT profiler deployed with the bongo plankton net tow system at Standard and Intermediate stations. The upcast portion of the tow is the most reliable and that is what is reported here. These profiles do not contain the parameters: light transmission, fluorescence, and scalar par. The primary version, in most cases, is a composite of both the Mark-5 and
* SEACAT CTD casts. These casts have been extracted from their respective cruise files and sorted by time. As a result, the reported cast and station numbers are frequently duplicated and random in order. When present, SeaBird profiles are identified with a one hundred series cast number to distinguish from a Mark-5 profile, however, this convention is inconsistent and does not always appear in all cruises (primary link only).";

"The U.S. GLOBEC Georges Bank Program is a large multi- disciplinary multi-year oceanographic effort. The proximate goal is to understand the population dynamics of key species on the Bank - Cod, Haddock, and two species of zooplankton (Calanus finmarchicus and Pseudocalanus) - in terms of their coupling to the physical environment and in terms of their predators and prey. The ultimate goal is to be able to predict changes in the distribution and abundance of these species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.
The effort is substantial, requiring broad-scale surveys of the entire Bank, and process studies which focus both on the links between the target species and their physical environment, and the determination of fundamental aspects of these species' life history (birth rates, growth rates, death rates, etc).
Equally important are the modelling efforts that are ongoing which seek to provide realistic predictions of the flow field and which utilize the life history information to produce an integrated view of the dynamics of the populations.
The U.S. GLOBEC Georges Bank Executive Committee (EXCO) provides program leadership and effective communication with the funding agencies.";

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.
