PurposeResearch
ObjectivesThe primary objective of this cruise was to link the redox cycling of phosphorus to the distribution and partitioning of biogenic hydrocarbons in the ocean. The sampling methods used were very straightforward: seawater was collected at multiple depths using a CTD detector equipped with a Niskin bottle sampler. We also collected samples using small plankton nets. Samples were frozen or filtered, and stored for latter analysis at WHOI, UCSB, URI, and Columbia. Some samples were be used in simple experiments to measure how plankton respond to changes in seawater chemistry. The laboratory methods we used were ion-chromatography (for phosphorus analysis) and gas chromatography (for hydrocarbon analysis). Recent discoveries about chemistry of phosphorus and hydrocarbons in seawater has renewed interest in them. Both play an important role in the ocean and governing the ocean's part in regulating global climate.
