The BATS program uses a method developed by Knauer et al. (1979) which was used extensively in the VERTEX program. In summary, to trap oceanic sediment flux, BATS uses a floating array comprised of polycarbonate tubes (7 cm diameter by 53 cm height) containing a buffered brine solution, with polycarbonate filters at the bottom to collect flux. Four tubes are deployed at each depth (150, 200, and 300 meters) and three additional tubes for blank counts are prepared but not deployed. The floating sediment trap array with collection tubes is deployed during monthly BATS cruises for a target time of 72 hours, but deployment time is subject to change depending on weather and/or emergency conditions. After recovery, the filters are examined under a microscope to remove swimming zooplankton caught on the traps to prevent skewed end results. Three samples from each depth are acidified to remove inorganic carbon before measuring organic carbon and nitrogen using a CE440 Elemental Analyzer, while the remaining non-acidified sample is used for total carbon estimates. Additional tubes are also prepared and deployed (three per depth) for phosphorus samples that are analyzed at Bigelow Laboratory of Ocean Sciences using a separate analytical procedure supervised by Dr. Michael Lomas."; String title "[BATS sediment trap particle flux] - Determination of carbon, nitrogen, and phosphorus content in sinking particles at the Bermuda Atlantic Time-series Study (BATS) site from December 1988 to December 2024 using a Particle Interceptor Trap System (PITS) (Bermuda Atlantic Time-series Study)"; Float64 Westernmost_Easting -64.298; } }
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").
