How+do+algae+blooms+move?

Harmful or non-Harmful Algae Blooms occur unrelated to tidal movement, but can tidal movement influence blooms? According to [|satellite evidence], bloom "migration" movements correlate with sea current and wind directions. But humans can be involved, too. According to the [|Northwest Fisheries Science Center], hamful algal cysts can be transported via surface and deep currents, as well as via oceanic ships. 1239894228

"The two views show the shoreward migration of the algal bloom." -- //Red Tide Strands South African Rock Lobsters, NASA// 1239894228

The above diagrams, taken from the [|Harmful Algal Blooms Observing System (HABSOS)], show toxicity levels and algae concentration in certain areas off of the coast of Louisiana. The first image is of January-December 1997, while the second one is of January-December 1998. A slight shift in the position of the algae concentrated level can be seen, indicating a shift that is both slow and of minimum magnitude. This shift suggests that although rapid movement due to human impact, oceanic currents, and wind influences is possible, movement of algae bloom that occurs on a slower scale is also possible. user:DavidSu
