The Bay of Algeciras (BA) is a marine environment subject to high levels of anthropogenic pressure. Here we analyze
observations collected at the Bay and the results of an ocean circulation model to investigate its circulation and variability. Special
attention is paid to the identification of the mechanisms enhancing the exchange of water with the adjacent Strait of Gibraltar and
therefore contributing to maintain satisfactory levels of water quality.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
