Blog on CLIVAR repeat hydrography section
The aim of this cruise is to investigate how much anthropogenic (generated by human activity) carbon dioxide has been taken up by the ocean. Atmospheric CO2 concentrations have increased rapidly since the start of the industrial revolution (circa 1850).
June 4 to August 11, 2003: The A16N cruise took place aboard the NOAA ship Ronald H. Brown under the auspices of the National Oceanic and Atmospheric Administration (NOAA). The first hydrographic leg (June 19 - July 10) was from Reykjavik to Funchal, Madeira along the 20°W meridian and the second leg (July 15 - August 11) continued operations from Funchal to Natal, Brazil on a track southward and ending at 6°S, 25°W. The research was the first in a decadal series of repeat hydrography sections jointly funded by NOAA-OGP and NSF-OCE as part of the CLIVAR/CO2/hydrography/tracer program.
Ten years later... : August 3, 2013: The NOAA research vessel, Ronald H. Brown, leaves Reykjavik, Iceland to embark on a voyage that will reoccupy the same cruise track as it did 10 years ago. On board are scientists from fourteen universities/institutions, including two from EOAS/FSU (Bill landing and Rachel Shelley). In fact, many of the same scientists (and many new ones) are on board, excited to see differences and/or similarities in their comparison with their earlier data from line A16N.
