Line W; A Sustained Measurement Program Sampling in the North Atlantic Deep Western Boundary Current and Gulf Stream at 39N

Lead PI: Dr. William Massie Smethie

Unit Affiliation: Geochemistry, Lamont-Doherty Earth Observatory (LDEO)

March 2008 - February 2015
Inactive
Atlantic Ocean
Project Type: Research

DESCRIPTION: Water samples will be collected and analyzed for CFCs 11, 12, and 113, SF6,and I-129 on annual hydrographic cruises. 26 Stations with be taken with up to 24 samples each per cruise. CFC and SF6 concentrations will be measured at sea, but I-129 4-6 months later. Data acquired will be used to investigate variability in water mass properties, circulation pathways, and water mass ages/transit times.
