ing epibiotic and pelagic communities. These icebergs can be compared to estuaries that supply surrounding coastal regions with nutrients. In that respect, icebergs may be thought of as “Lagran-gian estuaries, ” drifting through the Southern Ocean while enriching the surrounding pelagic zone. Our preliminary studies suggest that free-drifting icebergs and their associated communities could serve as areas of increased production and sequestration of organic carbon to the deep sea, a process unaccounted for in current global carbon budgets (33).
