Seawater intrusion is either caused by groundwater extraction or increased in sea level. For every 1-foot of freshwater depression (0.30 m), sea-salty waters rises 40 feet (12 m) as the cone of depression forms. [1] Salinization of groundwater is one of the main water pollution ever produced by mankind or from natural processes.
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...
A United States Geological Survey report found that with sea levels rising because of climate change, Southern California could lose up to two-thirds of its beaches by 2100.
Ocean surface topography is also used to understand how the ocean moves heat around the globe, a critical component of Earth's climate, and for monitoring changes in global sea level. The collection of the data is useful for the long-term information about the ocean and its currents.
"The ocean is more fragile than it used to be with climate change," Everts said "It’s not the 'endless reservoir' as they call it — it's a fragile ocean and the plants are industrializing but ...
A problem exists because our human-built world keeps getting in the way of the rising sea. But this current story of our coast does not have to end in disaster. We can choose to act, to reconsider ...
The California Water Plan (Water Plan) is the State of California’s long-term strategic plan for managing and developing water resources throughout the state. The Water Plan is mandated by California Water Code Sections 10004–10013, [ 1 ] and the California Department of Water Resources (DWR) is required to update the plan every five years ...
