B53A:
From WOCE through CLIVAR to GO-SHIP: Results from Global Repeat Hydrographic Surveys I


Session ID#: 11453

Session Description:
For the past 25 years, countries from around the world have participated in obtaining multiple, high-quality, repeat, global, hydrographic transects. The 1990’s World Ocean Circulation Experiment (WOCE) included some 30 countries. It focused on improving our understanding of ocean circulation, heat and carbon transport through the acquisition of a one-time global survey. The JGOFS program that sought to investigate mechanisms controlling concentrations of inorganic carbon and associated biogeochemical parameters and fluxes augmented WOCE. Ten years later CLIVAR began repeating transects focused on trends in ocean climate. The international Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) carries this task forward by identifying natural variability and anthropogenic changes since WOCE.

 In this session, we invite contributions using and interpreting these physical, chemical and biological observations. The session will highlight research that presents and interprets changes that have occurred over the last 25 years using the multitude of observed properties. A full range of contributions is solicited from surface to bottom waters based on rosette, underway or float observations. All avenues of investigation are welcome, including those using related data, as well as modeling and remote sensing studies performing comparisons and/or assimilations.
