Furthermore, Sargassum contains … The genus is characterized by a conspicuous stem like axis with distinct foliar blades. The largest members can reach several metres in length. Given the detection limit of 0.2% coverage within MODIS 1-km pixels (Wang & Hu, 2016 ), the lowest biomass density measured from a MODIS pixel is 2.80 g/m 2 , higher than most field-measured values. Marine mammals and commercial fishes, including tuna and mahi-mahi, also inhabit the Sargassum mats. and . The Commission facilitates voluntary collaboration for the conservation of the Sargasso Sea, exercises a stewardship role for this unique high seas ecosystem and is mandated to keep its health, productivity and resilience under continual review.
