ECOHAB: Tester_P - Gulf of Mexico Chlorophyll from 1998-10-05 to 1998-11-19 (NCEI Accession 0000536)

Chlorophyll a is a standard measure for phytoplankton biomass. Routinely, samples for extracted chlorophyll a values are filtered at sea, stored in liquid nitrogen, transported on dry ice and kept at -80 degrees Celsius until extracted. These values are used to examine the relationship between Karenia brevis cell counts, water column toxin levels and chlorophyll a pigment content.
