Healthy salt marsh. In salt marshes, early ecologists like Eugene Odum and John Teal sparked the current bottom-up paradigm in ecology through work on Sapelo Island, GA (U.S.A) that stressed the dominant role of physical factors like temperature, salinity, and nutrients in regulating plant primary productivity and ecosystem structure (Teal 1962, Odum 1971).
Coastal blue carbon includes mangroves, salt marshes and seagrasses. These make up a majority of ocean plant life and store large quantities of carbon. Deep blue carbon is located in international waters and includes carbon contained in "continental shelf waters, deep-sea waters and the sea floor beneath them". [4]
Carbon sequestration is the process of storing carbon in a carbon pool. [2]: 2248 It plays a crucial role in limiting climate change by reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called biosequestration) and geologic. [3]
Salt marsh dieback results in the death of marsh-specific plants and the erosion of the landscape. High salt marsh dieback, or salt marsh browning, is the primary force in salt marsh degradation in the high marsh. The general effect is that the plants in the marsh die off and brown, leaving dead organic matter, and ultimately open sediment.
This is a list of Superfund sites in Ohio designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law.The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

Mangroves, salt marshes and seagrasses make up the majority of the ocean's vegetated habitats. They only equal 0.05% of the plant biomass on land. But they store carbon 40 times faster than tropical forests. [132] Bottom trawling, dredging for coastal development and fertilizer runoff have damaged coastal habitats.
Ohio regulators have approved of subsidies totaling more than $100 million for two coal-fired plants, a legacy of the House Bill 6 scandal. Ohio regulators OK $100 million in subsidies for 2 aging ...
The salinity levels in brackish marshes can range from 0.5 ppt to 35 ppt. [2] Marshes are also characterised by low-growing vegetation and bare mud or sand flats. [3] Due to the variations in salinity, brackish marshes create a distinctive ecosystem where plants from either freshwater or saltwater marshes can co-inhabit. [4]
