Abstract

Sea currents are continuous movements of seawater, as a result of combined influence of wind, temperature and salinity level. Like sea waves, sea currents influence movements of seawater particles, but they have no such strengths to damage the organisms. Negative influences of currents are lifting of sediments that can cause abrasion of rocks, covering of organisms and preventing of accepting of larvae. However, currents are necessary for life of many benthic organisms, especially of filtering and static organisms. Currents bring nutrients. They are useful to tunnel-digging organisms because they bring them oxygen, nutrients, and take away carbon dioxide and excretion products. Sea currents are important for fish migration. They play a vital role in distribution of plankton organisms and larvae.
