BLUE CARBON and SEAGRASS

“Blue Carbon” is the scientifically recognized term defining carbon stored by coastal ecological systems. These systems of seagrasses, mangroves, salt marshes, and seaweed, cover less than 0.5% of the seabed, are equal in size to about 0.05% of the biomass on land, and are…

GLOBAL OCEAN CONVEYOR BELT: Changes due to Global Warming

Sea water along the equatorial area gets heated by the sun, and the warmed water forms a stratification layer above the colder lower water. Eastern Trade Winds caused by Earth’s rotation and atmospheric temperatures push this water layer, creating the Global Ocean Conveyor Belt…
