Glaciomarine sediment is a general term to describe inorganic and organic material deposited in a marine setting by a combination of glacier- and marine-related processes. (This term is equivalent to glacimarine and glacial marine). These sediments provide valuable records of ice sheet fluctuations because they occur beyond the limit of glacial erosion or cover older glacial erosional surfaces. The appearance and physical characteristics of glaciomarine sediments can be highly varied depending on the relative influence of marine and glacial depositional processes. Primary factors controlling the sediment characteristics include: volume of meltwater input, residence time and melt rate of icebergs, and biogenic production (Figure G48). Debris concentrations in glacier ice, extent of sea ice, and the strength of ocean currents are also important. Sediment redeposition by mass movements is common in glacio-marine environments; debris flow and turbidite deposits may be interbedded with...
