- Title
- Chlorophyll and phaeopigments measured from discrete bottle samples from CCE LTER P0904 student cruise in the California Current System, determined by extraction and bench fluorometry, April 2009.
- Abstract
- Discrete bottle samples taken from various depths in the California Current System aboard CCE LTER P0904 student cruise. Samples were frozen aboard the ship and taken back to the lab for extraction and analysis. Samples are filtered (known volumes) onto GF/F filters. The filters are placed into culture tubes containing 90% acetone, and the fluorescence of the samples is read on a fluorometer after 24 to 48 hours. The samples are then acidified to degrade the chlorophyll to phaeopigments (non-photosynthetic pigments) and a second reading is taken. The readings prior to and after acidification are used to calculate concentrations of both chlorophyll a and phaeopigments (i.e. phaeophytin).
