Description

This cruise provided the opportunity to expand the database the PI's are amassing on Synechococcus diversity and distribution for the NSF project “The role of iron (Fe) in controlling in situ distributions and activities of marine Synechococcus" (OCE-0825922) into an area that has not been well studied, and also provided the opportunity to test out hypotheses with controlled experimental manipulations of Fe, light, and temperature in the field.

Science objectives: Documenting N2 fixation in N deficient waters of the Eastern Tropical South Pacific.

Science Activities: Upper water column biogeochemistry, shallow and deep sediment trap deployment at six major (>24h) stations in the Peru Basin.

Cruise information and original data are available from the NSF R2R data catalog.
