Expanding Greenland seagrass meadows contribute new sediment carbon sinks
Unidad de excelencia María de Maeztu MdM-2015-0552 The loss of natural carbon sinks, such as seagrass meadows, contributes to grenhouse gas emissions and, thus, global warming. Whereas seagrass meadows are declining in temperate and tropical regions, they are expected to expand into the Arctic with...
