The transport of elements from terrestrial sources to the open ocean is particularly important in the Arctic, where continental shelves comprise half the ocean area (Jakobsson, 2002) and over 10% of the world’s river water is discharged (McClelland et al., 2012). Climate change is further increasing land-ocean exchange by thawing permafrost, increasing river discharge, and enhancing coastal erosion (Günther et al., 2013; Moon et al., 2021).
