The site is located at 23ºS and 42ºW, in the city of Arraial do Cabo, Rio de Janeiro state. The area is influenced by the upwelling of SACW (South Atlantic Central Water), from approximately 300 meters depth, with temperatures ranging from 13 to 18 ° C. The occurrence of this phenomenon is due to topographical features, meteorological and hydrological, unique in this region. This upwelling has attracted attention because of the great fishing productivity, motivating many studies on this issue, especially on the oceanographic processes involved. This has led to the creation of the second Marine Extractive Reserve of Brazil, the RESEX-Mar Arraial do Cabo. The results coming from LTER RECA contributes to the consolidation of Extractive Reserve, through the provision of scientific information generated in different studies.
