Bermuda Atlantic Ocean Time-Series Hydrographic and Productivity Data

Oceanographic measurements from the Bermuda Atlantic Time-series Study (BATS), a 10-year project from 1988 to 1998 funded by the NSF. The dataset includes hydrographic, CTD, sediment flux, primary productivity, and HPLC pigment data collected near Bermuda. The study was part of the international Joint Global Ocean Flux Study (JGOFS).

Use Cases

• Model phytoplankton community dynamics using HPLC pigment columns like Fucoxanthin and 19'-Hexanoyloxyfucoxanthin.
• Analyze relationships between nutrient concentrations (no3+, po4, sio4) and primary production rates from light/dark bottle experiments.
• Study carbon export by correlating sediment trap flux data (organic carbon flux, nitrogen flux) with surface water tco2 and poc measurements.
• Investigate water column structure by analyzing CTD profile data for depth, temperature, salinity, and beam attenuation coefficient.

Strengths

• Multi-decade temporal coverage from a 10-year core study (1988-1998).
• Multidisciplinary measurements combining hydrography, biology, and chemistry.
• Includes detailed HPLC pigment analysis with over 20 specific pigment columns.

Limitations

• Specific row counts and sample sizes for each data type are unknown.
• Data availability varies by year, with not all measurements for all years.
• Geographic coverage is limited to a single open-ocean site near Bermuda.
