Figure 3: Schematic view of the main sea surface current system in the tropical and subtropical North Atlantic (red lines).
From: Collapse of the tropical and subtropical North Atlantic CO2 sink in boreal spring of 2010
CC denotes the Canary Current, NEC the North Equatorial Current, NECC the North Equatorial Counter Current, nSEC and sSEC denote the north and south South Equatorial Current respectively and NBC corresponds to the North Brazil Current. The location of the subduction region of the North Atlantic subtropical gyre is also indicated. The climatological sea surface current components, calculated for March for the period 1994–2013 is also shown for reference. These were computed from the Ocean Surface Current Analyses – Real time (OSCAR) data (1° resolution; JPL Physical Oceanography DAAC; developed by ESR). The maps were generated with Matlab 2016a, the M_Map 1.7 toolbox (https://www.eoas.ubc.ca/~rich/map.html) and using the ETOPO2 Global 2 Arc-minute Ocean Depth and Land Elevation (National Geophysical Data Center/NESDIS/NOAA/U.S. Department of Commerce. 2001. ETOPO2, Global 2 Arc-minute Ocean Depth and Land Elevation from the US National Geophysical Data Center (NGDC).
