| log in | [BATS HPLC pigments] - HPLC and fluorometric derived phytoplankton pigment concentrations from seawater collected at the Bermuda Atlantic Time-series Study (BATS) site from October 1988 through December 2023 (Bermuda Atlantic Time-series Study) | Data presented here contain HPLC derived phytoplankton pigments and fluorometric chlorophyll-a from the BATS site for years 1988 to 2023. Water samples are typically collected from 12 depths in the upper 250 meters of the water column, and then filtered under low vacuum through a 25mm GF/F filter. The filter is then flash frozen in liquid nitrogen and stored at -80 degrees C. Shoreside, analysis is performed on an HPLC using a method modified by Dr. R. Bidigare from the Wright et al. (1991) procedure. This method identifies the pigments chlorophyll-c3, chlorophyll-c2, peridinin, 19'-butanoyloxyfucoxanthin, fucoxanthin, 19'-hexanoyloxyfucoxanthin, prasinoxanthin, diadinoxanthin, alloxanthin, diatoxanthin, lutein, zeaxanthin, chlorophyll-b, chlorophyll-a, divinyl chlorophyllide-a, alpha and beta carotene. Additionally, chlorophyll-a and phaeopigments are analyzed using a fluorometric assay.\n\ncdm_data_type = Other\nVARIABLES:\nID (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nVessel (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nCruise_type (unitless)\nCruise_num (unitless)\nCast (unitless)\nCast_type (unitless)\nBottle_number (unitless)\nQF_Niskin_GoFlo (uniteless)\ndepth (m)\nQF_depth (unitless)\np1 (nanograms per kilogram (ng/kg))\nQF_p1 (unitless)\np2 (nanograms per kilogram (ng/kg))\nQF_p2 (unitless)\np3 (nanograms per kilogram (ng/kg))\n...

| log in | [BVAL pigments (BATS Validation cruises)] - HPLC and fluorometric derived phytoplankton pigment concentrations from seawater collected on BATS Validation cruises from June 1996 to July 2024 (Bermuda Atlantic Time-series Study) | Data presented here are discrete bottle HPLC derived phytoplankton pigments and fluorometric chlorophyll-a for BATS validation (BVAL) cruises from June 1996 (BVAL cruise #50016) through June/July 2024 (BVAL cruise #50061). Water samples are typically collected from 7-12 depths in the upper 250 meters of the water column, and then filtered under low vacuum through a 25mm GF/F filter. The filter is then flash frozen in liquid nitrogen and stored at -80 degrees C. Shoreside, analysis is performed on an HPLC using a method modified by Dr. R. Bidigare from the Wright et al.

Through enhanced rates of consumption, surface bacterioplankton communities can also reduce the amount of dissolved organic carbon (DOC) available for export from the surface ocean. The present study investigated the direct effects of elevated pCO2 on bacterioplankton removal of several forms of DOC ranging from glucose to complex phytoplankton exudate and lysate, and naturally occurring DOC. Elevated pCO2 (1000 \\u2013 1500 ppm) enhanced both the rate and magnitude of organic carbon removal by bacterioplankton communities compared to low (pre-industrial and ambient) pCO2 (250 \\u2013 ~400 ppm). The increased removal was largely due to enhanced respiration, rather than enhanced production of bacterioplankton biomass.\n\ncdm_data_type = Other\nVARIABLES:\nexperiment (unitless)\nsite (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nbottle_number (unitless)\ndoc_addition (unitless)\ntarget_pCO2 (Target P CO2, parts per million (ppm))\ntime_point (unitless)\ntime_days (unitless)\ndate (unitless)\nbact_abun_x10e6_avg (cells per milliliter)\nbact_abun_x10e6_stderr (cells per milliliter)\nbact_abun_x10e6_stdev (cells per milliliter)\ntoc_avg (micromoles per liter (uM))\ntoc_stderr (micromoles per liter (uM))\ntoc_stdev (micromoles per liter (uM))\n | https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_472032_fgdc.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_472032/index.htmlTable | https://www.bco-dmo.org/dataset/472032
