Sea level rises on the Brazilian coast four millimeters per year

6 05 2010

According to data collected at ports along the Brazilian coast, sea level is rising in Brazil about 40 centimeters (cm) per century, or 4 millimeters (mm) per year (mm / year). The finding is the Laboratory of Ocean Tides and Temporal Processes (Maptolab) Institute of Oceanography (IO) of the University that investigates changes in sea level along the Brazilian coast, from measurement series that began in 1980.

Data analysis is done by means of daily variations, seasonal mean and annual mean sea level, which allows us to estimate the local variation of the long term.
