PL44C:
From WOCE Through CLIVAR to GO-SHIP: Results from Global Repeat Hydrographic Surveys I Posters


Session ID#: 28697

Session Description:
As part of the global repeat hydrography effort, researchers from around the world have worked to measure vertical profiles of seawater properties with high spatial resolution, precision, and accuracy approximately once per decade. These measurements are made along pre-defined sections that cross the major ocean basins. The first detailed surveys were conducted by the 1990s World Ocean Circulation Experiment (WOCE). Major sections were repeated in the 2000s as part of the Climate Variability and predictability program (CLIVAR). Now, the Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) is carrying this observation strategy into a third decade. Repeat hydrographic measurements have proven critical for revealing variability and long term trends in ocean heat content, freshwater cycling, anthropogenic and natural carbon storage, circulation patterns, acidification, nutrient distributions, and other natural and anthropogenic tracers. These cruises have also provided support for ancillary measurements and other observation programs (e.g. Argo and remote sensing).

In this session, we invite contributions from those who are interpreting these physical, chemical, and biological observations, or using them to construct or validate ocean circulation models or property estimation algorithms. Submissions from researchers who rely on repeat hydrography cruises for in situ sensor deployments or remote sensor calibration/validation are also invited.
