aquatic : growing or living in or frequenting water — Webster
Aquatic ecosystem An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. — Wikipedia

Marine biology is the scientific study of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
A large proportion of all life on Earth lives in the ocean. The exact size of this large proportion is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth’s surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and thermal vents, tidepools, muddy, sandy and rocky bottoms, and the open ocean (pelagic) zone, where solid objects are rare and the surface of the water is the only visible boundary. The organisms studied range from microscopic phytoplankton and zooplankton to huge cetaceans (whales) 25–32 meters (82–105 feet) in length. Marine ecology is the study of how marine organisms interact with each other and the environment. — Wikipedia

Researchers investigating the exposure of small mammals to plastics in England and Wales have found traces in the feces of more than half of the species examined.
- Chesapeake Bay 'dead zone' predicted to be 13%...on June 28, 2022 at 7:48 pm
This summer's Chesapeake Bay "dead zone" is expected to be smaller than the long-term average, according to a forecast released today by researchers from the University of Michigan, Chesapeake Bay Program, University of Maryland Center for Environmental Science and U.S. Geological Survey.
- Climate change is shrinking and fragmenting...on June 28, 2022 at 5:22 pm
Salmon famously travel hundreds of miles upstream to reach their home waters to spawn, but climate change is shrinking their destination. A new study offers high-resolution details on how Chinook salmon habitats are being lost on Bear Valley Creek, a headwater stream of the Salmon River in central Idaho.

- Climate change in oceanwater may impact mangrove...on June 30, 2022 at 3:44 pm
Researchers examined 21st century changes in ocean-surface temperature, salinity, and density, across mangrove forests worldwide. Their study suggests that changes in surface-ocean density may impact the dispersal patterns of widely distributed mangroves species, and more likely so in the Indo-West Pacific region, the primary hotspot of mangrove diversity.
