Coastal sediment transport (a subset of sediment transport) is the interaction of coastal land forms to various complex interactions of physical processes. [1] [2] The primary agent in coastal sediment transport is wave activity (see Wind wave), followed by tides and storm surge (see Tide and Storm surge), and near shore currents (see Sea#Currents) .

Offshore energy is the generation of electricity using ocean-based resources. This includes using wind , thermal [ clarification needed ] , wave , and tidal movement to convert to energy. [ 56 ] Understanding the seafloor and geological features can help develop the infrastructure to support these renewable energy sources . [ 57 ]
Coastal sediment supply is the transport of sediment to the beach environment by both fluvial and aeolian transport. While aeolian transport plays a role in the overall sedimentary budget for the coastal environment, it is paled in comparison to the fluvial supply which makes up 95% of sediment entering the ocean.

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 ...
The smaller sediments present under this layer of large gravel have a lower possibility of movement and total sediment transport decreases. This is called armouring effect. [13] Other forms of armouring of sediment or decreasing rates of sediment erosion can be caused by carpets of microbial mats, under conditions of high organic loading. [14]
On land most phosphorus is found in rocks and minerals. Phosphorus-rich deposits have generally formed in the ocean or from guano, and over time, geologic processes bring ocean sediments to land. Weathering of rocks and minerals release phosphorus in a soluble form where it is taken up by plants, and it is transformed into organic compounds.
A group of recyclers in the Philippines is trying to ease the country's worsening plastic waste crisis by turning bottles, single-use sachets and snack food wrappers that clog rivers and spoil ...
The Department of Environment and Natural Resources (Filipino: Kagawaran ng Kapaligiran at Likas na Yaman), abbreviated as DENR, is the executive department of the Philippine government responsible for the conservation, management, development, and proper use of the country’s environment in natural resources, specifically forest and grazing lands, mineral resources, including those in ...
