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

Coastal waters are unexpected hotspots for...

Nitrogen fixation is surprisingly high in the ocean's coastal waters and may play a larger role than expected in carbon dioxide uptake, a new study shows. The findings -- based on thousands of samples collected in the western North Atlantic -- upend prevailing theories about where and when nitrogen fixation occurs, and underscore the need for scientists to revisit the global distribution of marine nitrogen fixation and reevaluate its role in the coastal carbon cycle.

How coral bleaching threatens Caribbean...
on February 21, 2019 at 4:04 pm
A new study uses environmental, socioeconomic and management data from 30 Caribbean islands to identify which communities may be most at risk from the social and ecological effects of coral bleaching, which occurs when warm water causes coral polyps to expel algae living in their tissue. The analysis shows that independent island nations, such as Cuba and Jamaica, may be less vulnerable to coral bleaching than island territories like Saint Barthélemy. […]
How to save a seabird
on February 21, 2019 at 4:04 pm
A new study outlines more than a decade of success in reducing seabird bycatch in Alaska's longline fisheries, and where there's still room for improvement. […]
Researchers discover a flipping crab feeding on...

Researchers have documented a group of tanner crabs vigorously feeding at a methane seep on the seafloor off British Columbia -- one of the first times a commercially harvested species has been seen using this energy source. […]

By studying fish raised in aquaculture, researchers have shed new light on the mechanisms by which antibiotic resistance genes are transferred between bacteria. According to their study, those mechanisms are more varied than previously thought. […]

Scientists reveal impacts of anthropogenic...
on February 22, 2019 at 3:31 pm
Excess nutrients from fertilizer application, pollution discharge, and water regulations outflow through rivers from lands to oceans, seriously impacting coastal water quality and ecosystems. Understanding the effects of human activities on riverine nitrogen movement is important for water environmental management and nitrogen cycle research. […]
Ecosystem responses to dam removal complex, but...
on February 21, 2019 at 5:27 pm
In the United States, the removal of dams now outpaces the construction of new ones—with more than 1,400 dams decommissioned since the 1970s—and a new study suggests that the ecosystem effects of dam removal can be predicted. […]
Radio-tracking dolphins reveals intimate details...

Using telemetry units in hospitals to monitor patient health is standard practice. Now, a similar approach is proving to be invaluable for dolphins, too. Researchers from Florida Atlantic University's Harbor Branch Oceanographic Institute, Hubbs-SeaWorld Research Institute and collaborators have conducted the most extensive radio-tracking effort of bottlenose dolphins in the Indian River Lagoon (IRL) using radio-telemetry.

Climate change and the loss of wetlands may contribute to increased levels of mercury concentrations in coastal fish, according to a Dartmouth College study. […]
Marine scientists find toxic bacteria on...
on February 12, 2019 at 2:00 pm
A field survey conducted by a team of marine scientists from the National University of Singapore (NUS) has uncovered toxic bacteria living on the surfaces of microplastics, which are pieces of plastic smaller than five millimetres in size, collected from the coastal areas of Singapore. These bacteria are capable of causing coral bleaching, and triggering wound infections in humans. […]
