Deployment: TN277

2012-02-29 - 2012-03-11 Eastern North Pacific Ocean Platform:R/V Thomas G. Thompson (vessel)

Description

The POWOW#1 cruise was a trip of opportunity to sample along temperature gradients and test out new protocols. The primary goal of this cruise was to measure the abundance, diversity and activity of Prochlorococcus and associated bacterial and viral communities across temperature (and other environmental) gradients to understand how climate change may impact ocean ecology and biogeochemistry. There are many additional scientific and broader impact goals including characterizing oxidative stress and investigating nitrogen uptake/utilization molecular diversity.

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