2014 PIRATA Northeast Extension (PNE) cruise
The PIRATA Northeast Extension
project is a joint AOML/PMEL effort to collect observations in the climate-critical Tropical North Atlantic region. Maintaining observations requires an annual research cruise in the region.The 2014 PNE cruise
was conducted on the UNOLS R/V Endeavor from
December 29, 2014 to February 11, 2015, from Barbados to San Juan, Puerto Rico.
Participating NOAA/AOML personnel were Rick Lumpkin (chief scientist), Zach Barton, Shaun Dolk,
Erik Valdes and Kyle Seaton; NOAA/PMEL personnel were J. Michael Strick and Korey Martin.
During the cruise, four ATLAS PNE moorings were recovered
and redeployed, a T-FLEX mooring was recovered and redeployed at 4N
23W with a large number of AOML-supported current meters to study
upper ocean velocity shear, five subsurface hydrophone moorings were
recovered, 51 CTD casts with LADCP were conducted to a depth of 1500m,
and 12 surface drifters were deployed. A suite of additional underway observations were also collected.
All PNE moorings are currently successfully transmitting data on the
Global Telecommunications System for studies of Atlantic Tropical climate variability. The
hydrophone mooring data will be used to study seismic activity in the
