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

Preventing collapse after catastrophe
on April 25, 2019 at 8:23 pm
As the impacts of climate change escalate, ecosystems will likely undergo events that will disrupt entire populations. In marine ecosystems, anthropogenic warming has subjected organisms to elevated temperatures, oxygen loss, and acidification. The increased frequency and severity of catastrophic events may inhibit a population's ability to recover and, in turn, may spur collapse. […]
Maximizing conservation benefits
on April 25, 2019 at 8:23 pm
Overexploitation and population collapse pose significant threats to marine fish stocks across the globe. While certain fish populations have already collapsed, research indicates that nearly one third of fisheries worldwide are currently impacted by overharvesting. […]
Pole-to-pole study of ocean life identifies...

An international team has conducted the first-ever global survey of the ecological diversity of viruses in the oceans during expeditions aboard a single sailboat. They identified nearly 200,000 marine viral species, which vastly exceeds the 15,000 known from prior ocean surveys of these waters and the approximately 2,000 genomes available from cultured viruses of microbes. Their findings have implications for understanding issues ranging from evolution to climate change. […]

Study reveals vast diversity of ocean microbes
on April 24, 2019 at 4:27 pm
Advanced molecular techniques have revealed the diversity of a little-understood group of ocean microbes called protists, according to a new publication in Scientific Reports. The project analyzed samples collected by the global Tara Oceans expedition, documenting genomes that will help researchers identify protists throughout the ocean. […]

Monitoring concentrations of dissolved organic carbon in Maine lakes before and after severe rainstorms could inform management strategies to help ensure consistent, high-quality drinking water, according to University of Maine researchers. […]
Bacterial mix helps predict future change
on April 17, 2019 at 11:19 am
A controlled, laboratory approach, along with computer simulations, has helped KAUST researchers to show that bacterial communities can homogenously disperse within aquatic ecosystems, even with slow-flowing water and the persistence of their preferred localized conditions. […]
