Marine resources are resources (physical and biological entities) that are found in oceans and are useful for humans. The term was popularized through Sustainable Development Goal 14 which is about "Life below water" and is one of the 17 Sustainable Development Goals established by the United Nations in 2015.
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
The ocean is an example of a natural resource. Ocean waves can be used to generate wave power, a renewable energy source. Ocean water is important for salt production, desalination, and providing habitat for deep-water fishes. There is biodiversity of marine species in the sea where nutrient cycles are common.
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 ]
This compound is a major energy source, forming the basis of the sulfur cycle in hydrothermal vent ecosystems. In the colder waters surrounding vents, sulfur-oxidation can occur using oxygen as an electron acceptor ; closer to the vents, organisms must use alternate metabolic pathways or utilize another electron acceptor, such as nitrate.
Natural gas deposits are also the main source of helium. Heavy crude oil , which is much more viscous than conventional crude oil, and oil sands , where bitumen is found mixed with sand and clay, began to become more important as sources of fossil fuel in the early 2000s. [ 33 ]
Marine energy, also known as ocean energy, ocean power, or marine and hydrokinetic energy, refers to energy harnessed from waves, tides, salinity gradients, and temperature differences in the ocean. The movement of water in the world's oceans stores vast amounts of kinetic energy , which can be converted into electricity to power homes ...
According to the World Bank, [3] the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem." European Commission defines it as "All economic activities related to oceans, seas and coasts.
