Schofield is the third, and current lead, beginning in the 2008-2009 season. Methods have been kept consistent as much as possible over the full time series and different Principal Investigators. Phytoplankton have a suite of accessory pigments in addition to Chlorophyll a, including other Chlorophyll's (e.g. Chlorophyll b), Xanthophylls, and Carotenes. These accessory pigments can be used as chemotaxonomic markers to assess the composition and distribution of the phytoplankton community. For example, Fucoxanthin is a marker pigment of Diatoms, whereas Alloxanthin is a marker pigment of Cryptophytes. Accessory pigments also assist in photoacclimation and photoprotective processes. Water samples are collected throughout the water column at stations within the Palmer LTER region (primarily B and E, to 50m and 65m respectively). Water samples are filtered onto GF/F filters, and filters kept frozen at -80C until analysis. HPLC analysis is completed following Wright et al (1991). Following the guidelines set by NASA SeaHARRE, we use an internal standard and replicate injects on the HPLC to track recovery and replicability of the pigment extraction methods. Data is unavailable for the Palmer 2009-2010 season due to instrumentation problems and for the Palmer 2011-2012 season due to a freezer failure which resulted in the loss of samples. \n Funding and support provided by the National Science Foundation John Kerfoot National Science Foundation kerfoot@marine.rutgers.edu https://pal.lternet.edu/ information web browser Background Information Background information from the source information pointOfContact chlorophyll habitats marine measurements nutrients Population Studies Primary Production primary production theme Palmer LTER project time depth latitude longitude concentration_of_chlorophyll_in_sea_water concentration_of_chlorophyll_in_sea_water concentration_of_chlorophyll_in_sea_water concentration_of_chlorophyll_in_sea_water concentration_of_chlorophyll_in_sea_water concentration_of_chlorophyll_in_sea_water mass_concentration_of_chlorophyll_a_in_sea_water theme CF Standard Name Table v77 All data contained herein is licensed under the LTER Network Data Access Policy (https://lternet.edu/data-access-policy/).
