Title: CTD/O2 measurements collected on a climate and global change cruise (WOCE section P13) along 165 deg E during August-October 1992. Data report

Technical Report ·
OSTI ID:26289

In support of NOAA`s Climate Program, PMEL scientists have been measuring the growing burden of greenhouse gases in the thermocline waters of the Pacific Ocean and the overlying atmosphere since 1980. During this cruise, hydrographic and chemical measurements began with a series of closely spaced stations extending from the Kamchatka Peninsula across the western boundary current regime. The section then crossed the northern end of the Kuril-Kamchatka Trench and extended southward along 165 deg E from 51.5 deg N to 5 deg S crossing such major features as the North Pacific subpolar gyre, Kuroshio Extension, subtropical gyre, and the equatorial current system. Full water column CTD/O2 profiles and a suite of anthropogenic and natural tracers including chlorofluorocarbons (CFCs), helium-tritium, radiocarbon, total CO2, alkalinity, dissolved oxygen, dissolved nutrients and salinity were collected. These measurements will be used to study the distribution, sources, and formation rates of water masses and their flow patterns and time scales. The CFC and tritium measurements will be of use in studying the rates of upper and intermediate water mass formation and transport processes. CO2 measurements will be used to study the flux of CO2 from atmosphere to ocean and the importance of this region as a sink for CO2.
