Description

Monthly zooplankton samples were collected at the Bermuda Atlantic Time-series Study (BATS)site (31°40’N, 64°10’W), starting in April 1994. Double oblique tows were taken to 200-m depth with a 0.8-m², 200-µm mesh net. Replicate tows were taken during the day and night. Tow profiles were documented with a temperature/depth recorder (TDR) attached to the net. Each sample was split in half in the field. One ½ was used for size-fractionated (200, 500, 1000, 2000, and 5000 µm) wet and dry biomass estimates. The other ½ was preserved in formaldehyde for subsequent taxonomic analysis.

These are the original data sources for the BATS Zooplankton data base. JGOFS-BATS Zooplankton Sampling sheets (doc and pdf) contain field data for each tow (e.g., date/time, latitude/longitude, flowmeter counts). These sheets were eventually replaced by Madin Tow Summaries sheets (doc and pdf). Biomass worksheets (pdf and xls) contain size-fractionated wet and dry weight biomass measurements. Two types of TDRs were used, a Vemco Minilog TDR and a Star-Oddi DST centi-TD. Both record date- and time-stamped temperature and depth data. TDR BinFiles (bin) are the original binary files downloaded from the Minilog TDR and require Vemco Minilog software. TDR AscFiles (asc) are converted Minilog TDR binary files; the original binary files are not available. TDR CsvFiles (csv) are converted Minilog TDR binary files. DSTCenti files (dat) are the original data files downloaded from DST centi-TD.

Description

JGOFS-BATS Zooplankton Sampling sheets (folder)

File name BATSxxxyzz-JGOFS, where xxx = Cruise number, y = regular (0) or bloom (1) cruise, and zz = Tow number (zz = 00 indicates that all tows for a cruise are included in the file). (e) at the end of the pdf file name indicates corrections were made to the original doc files.

Madin Tow Summaries sheets (folder)

File name BATSxxxy-Madin, where xxx = Cruise number and y = regular (0) or bloom (1) cruise.

Biomass worksheets (folder)

File name BATSxxxy-MadinBiomass, where xxx = Cruise number and y = regular (0) or bloom (1) cruise.

TDR/BinFiles (folder)

File name BATSvvvwxx-yyyy.zzz, where vvv = Cruise number, w = regular (0) or bloom (1) cruise, xx = Tow number (if two tows are contained in the file, they are separated by an ampersand "&"; if more than two tows are contained in the file, the first and last tows are separated with a hyphen "-"), yyyy = TDR number, and zzz = TDR deployment number.

TDR/AscFiles (folder)

File name BATSvvvwxx-yyyy.zzz, where vvv = Cruise number, w = regular (0) or bloom (1) cruise, xx = Tow number (if two tows are contained in the file, they are separated by an ampersand "&"), yyyy = TDR number, and zzz = TDR deployment number.
