Water samples were collected at the Bermuda Atlantic Time-series Study (BATS) site located 80 km southeast of Bermuda (31°40N, 64°10W) in the Sargasso Sea. Measurements were collected monthly and often biweekly during the core monthly BATS cruises and the BATS Bloom cruises (Feb to April) following the methods of Knap et al. (1997).

All bottle fires are included in this dataset, even those that do not have any BATS core parameters, to be of use with other measurements and studies.

Niskin bottles were deployed and accompanying CTD measurements were taken at the depths of water sample collection. Sample parameters include salinity, dissolved oxygen, dissolved inorganic carbon, alkalinity, nutrients (nitrate + nitrite, nitrite, phosphate, silicate), particulate organics (carbon, nitrogen, phosphorous), particulate silicate, total organic carbon and total nitrogen, total dissolved phosphorous, bacterial enumeration, and flow cytometry counts of picoplankton. The HPLC derived phytoplankton pigment data which are collected synoptically with many of the above parameters are reported separately (see https://www.bco-dmo.org/dataset/893521)
