This A13.5 GO-SHIP transect is a NOAA-led cruise, funded by the NOAA Global Ocean Monitoring and Observing (GOMO) program as well as the National Science Foundation (NSF). The U.S. GO-SHIP program is a part of the broader international GO-SHIP effort, which is sponsored by, among others, the World Meteorological Organization (WMO), the Intergovernmental Oceanographic Commission of the United Nations Education, Scientific and Cultural Organization (IOC-UNESCO), the United Nations Environment Programme (UN Environment), and the International Science Council (ISC). Observations from the GO-SHIP program are crucial for understanding the Earth’s climate system, detecting changes, and informing climate research, policy, and decision-making on an international scale. The A13.5 transect runs from Ghana to Bouvet Island in the eastern South Atlantic and repeats decadal measurements taken in 1983/84, 1995, and 2010 to investigate temporal changes in physical and hydrographic conditions.

Float status including number of completed profiles to date is available in the Float Status Table.

As part of this transect, on-board crew and researchers contributed to a GO-BGC A13.5 Expedition Log and a U.S. GO-SHIP blog that described life at sea while on an oceanographic expedition.

Associated documentation, shipboard validation data sets (if collected), and float data sets are available on our Shipboard Calibration and Validation Datasets page.

All 11 floats from the A13.5 expedition were adopted by schools in Alabama, California, Florida, Kansas, Nevada, New Jersey, New York, and Washington. Check out all adopted floats on the Adopt-a-float data table and photos of floats can be found on our Flickr page.
