Climate-ocean dynamics in this region, including a large counter-clockwise rotating gyre formed by major currents, affect distribution of marine life. Here we hypothesize that dynamics of this gyre, including interaction of gyre movements with the Ridge, also directly affect primary productivity by redistributing recycled silicate, fuelling the regional food web – from microbes to whales - with detectable impacts 1000s of km downstream via advective and mixing processes, and that these links could erode under climate change. Project results will advance understanding of how climate change affects productivities of food webs and sustainability of fisheries production and carbon sequestration, with socio-economic repercussions Støða: Fer í gongd << Back |
