Marine sediment | oceanography | Britannica
2021/1/26 · Marine sediment, any deposit of insoluble material, primarily rock and soil particles, transported from land areas to the ocean by wind, ice, and rivers, as well as the remains of marine organisms, products of submarine volcanism, chemical precipitates from seawater, and materials from outer space (e.g., meteorites) that accumulate on the seafloor.

Marine Sediment - an overview | ScienceDirect Topics
Marine Sediment Marine sediments are generally a combination of several components, most of them coming from the particles eroded from the land and the biological and chemical processes taking place in sea water. From: Encyclopedia of Ocean Sciences
Marine Sediments - an overview | ScienceDirect Topics
As a rule, marine sediments are dominated by the sulfur cycle, due to the fact that seawater usually has ∼28 mmol l −1 sulfate, which, after oxygen is depleted, becomes the major electron acceptor. Thus, marine sediments are notorious for sulfide production and for internal sulfur cycling.

C. Sedimentation in the Ocean - Deep-sea Sedimentation has 4 main sources for sediment: terrigenous material from the land (found mostly on the shelf), biogenous and hydrogenous from the sea, and volcanic from mid-ocean ridges and other active sites.

Glacial-Marine Sedimentation: Molnia, Bruce F.: 9780306414978: …
This volume of 18 papers describes the glacial-marine sedimentary environment in a variety of temporal and spatial settings. The volume's primary emphasis is the characteri zation of Quaternary glacial-marine sedimentation to show (1) the significant differences that exist between glacial marine environments in different geographic settings and (2) their resulting glacial-marine deposits ...
Sedimentation Rate - an overview | ScienceDirect Topics
Sedimentation Rate Sedimentation rates are highest (>20m/Ma) during the early to late Oligocene section at Sites U1333 and 1334, and in the early and middle Miocene at Sites U1337 and U1338. From: Developments in Marine Geology, 2014Related terms:

Biogenic Sedimentsare one of the most important constituents of marine sediments. As the name implies, these form directly or indirectly through biological activity. They are made of a variety of delicate and intricate structures mostly of skeletal remains of marine phytoplankton and zooplankton.

Subarctic Glacial-Marine Sedimentation: A Model | SpringerLink
The classic concept of glacial sedimentation in the marine environment is based on Antarctic models and most commonly recognizes only the presence of coarse-grained particles in a muddy matrix (diamicton) as evidence of glacial-marine sedimentation. Studies in Alaska adjacent to active glaciers and recently deglaciated areas suggest that this ...

Marine Sedimentation Systems
Our research focuses on the external forces and internal processes which have control on transport modes, patterns of deposition, and residence times in each of these marginal-marine sedimentation systems, and aims to identify coupling mechanisms between them.

Deep-sea Sedimentation The Deep sea has two main sources of sediment: 1. External - terrigenous material transported to oceans via rivers and wind, 2. internal - biogenic and authigenic from the sea.
Glacial‐Marine Sedimentation | Short Courses in Geology
Glacial-marine sedimentation is one of the more complex and least known aspects of sedimentation. A considerable volume of literature, however, does exist on the subject, especially describing ancient glacial-marine deposits [e.g., Anderson, 1983; Andrews and Match, 1983; Molnia, 1983].
