But whatever the source, it is Josefina Olascoaga’s goal to determine how much of a role ocean currents and wind play in moving the seaweed across the ocean. All figures, except for water (as percentage), are given as grams per 100 grams of dry matter. But while that nutrient, found in atmospheric particles transported by winds and deposited to the ocean and on land, can stimulate the growth of marine phytoplankton and terrestrial plants and lead to the sequestration of carbon dioxide, it could also be contributing to the growth of sargassum. Copyright: 2020 University of Miami. is 14–44% ash, 4–68% carbohydrates, 9–20% proteins and 0.5–3.9% lipids (%DW) (Holdt & Kraan, 2011). High levels of enterococci at the beach indicate fecal pollution from stormwater, pets and human sewage, and if the bacteria are ingested while swimming, it can cause gastrointestinal disease.
