P06E 2017

The Pacific Ocean P06E repeat hydrography line took place on board the RVIB Nathaniel B. Palmer from August 20, 2017 to September 30, 2017. The survey of P06E consisted of CTDO, rosette, LADCP, chipod, water samples and underway measurements. The ship departed from the port of Papeete on the island of Tahiti, French Polynesia and completed the cruise in the port of Valparaiso, Chile. A total of 106 CTDO/rosette/LADCP/chipod casts, including 2 test casts were performed. The stations were, for the most part, a reoccupation of P06E-2009 cruise. 31 UW Argo floats, 4 SOCCOM floats, and 6 drifters were deployed on P06W. CTDO data and water samples were collected on each CTDO, rosette, LADCP, and chipod cast, usually within 10 meters of the bottom. Water samples were measured on board for salinity, dissolved oxygen, nutrients, DIC, pH, total alkalinity and CFCs/SF6. Additional water samples were collected and stored for shore analyses of Nitrate 𝛿15N and 𝛿18O, DOC/TDN, 13C/14C, POC, HPLC, DOP and DON.
