Large Pacific Ocean Survey Nears Completion

Cruise track for P16N outlined in yellow.

June 24, 2015

From April–June 2015, scientists on the  NOAA ship Ronald H. Brown are collecting observations of Pacific Ocean water properties and currents from Tahiti to Alaska. This expedition is part of the US GO-SHIP Repeat Hydrography Program, an international effort to measure and observe the changing global ocean every decade.  This particular cruise fortuitously crossed the equator during a developing El Niño and shortly after a transition to the warm phase of the Pacific Decadal Oscillation, allowing study of how these climate variations affect ocean conditions such as biological production and heat transport.
