The Oceanic carbon cycle is a central process to the global carbon cycle and contains both inorganic carbon (carbon not associated with a living thing, such as carbon dioxide) and organic carbon (carbon that is, or has been, incorporated into a living thing). Part of the marine carbon cycle transforms carbon between non-living and living matter.
Ice rafting is the transport of various materials by floating ice. [1] Various objects deposited on ice may eventually become embedded in the ice. When the ice melts after a certain amount of drifting, these objects are deposited onto the bottom of the water body , e.g., onto a river bed or an ocean floor .
A higher concentration of microplastics in glaciers indicates that transport via wind is a significant pathway to distribute microplastics in the environment. Microplastics can accumulate in the whitecaps of ocean waves or sea foam and increase the stability of breaking waves, potentially affecting sea albedo or atmosphere-ocean gas exchange. [92]

Marine sediment, or ocean sediment, or seafloor sediment, are deposits of insoluble particles that have accumulated on the seafloor.These particles either have their origins in soil and rocks and have been transported from the land to the sea, mainly by rivers but also by dust carried by wind and by the flow of glaciers into the sea, or they are biogenic deposits from marine organisms or from ...
Subglacial streams can transport, deposit, and remove sediment from the glacier bed; this process is influenced by water supply and the amount and characteristics of the available sediment. [12] The size of sediment particles, the slope of the subglacial stream’s channel, and the roughness of the bed all contribute to whether sediment is ...
A National Park Service report on Alaska's glaciers noted glaciers within Alaska national parks shrank 8% between the 1950s and early 2000s and glacier-covered area across the state decreased by ...
Coastal sediment transport takes place in near-shore environments due to the motions of waves and currents. At the mouths of rivers, coastal sediment and fluvial sediment transport processes mesh to create river deltas. Coastal sediment transport results in the formation of characteristic coastal landforms such as beaches, barrier islands, and ...
