The ocean and the marine parts of the cryosphere interact directly with, and are
affected by, the seafloor and its primary properties of depth (bathymetry) and shape
(morphology) in many ways. Bottom currents are largely constrained by undersea terrain
with consequences for both regional and global heat transport. Deep ocean mixing is
controlled by seafloor roughness, and the bathymetry directly influences where marine
outlet glaciers are susceptible to the inflow relatively warm subsurface waters - an issue
of great importance for ice-sheet discharge, i.e., the loss of mass from calving and
undersea melting. Mass loss from glaciers and the Greenland and Antarctic ice sheets,
is among the primary drivers of global sea-level rise, together now contributing more to
sea-level rise than the thermal expansion of the ocean. Recent research suggests that
the upper bounds of predicted sea-level rise by the year 2100 under the scenarios
presented in IPCC’s Special Report on the Ocean.....
