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

Ancient Adélie penguin colony revealed by...
on September 28, 2020 at 7:57 pm
Researchers encountered a puzzle at Cape Irizar, a rocky cape located just south of the Drygalski Ice Tongue on the Scott Coast, Ross Sea. He found both ancient and what appeared to be fresh remains of Adelie penguins, mostly of chicks, which frequently die and accumulate at these colonies. However, the 'fresh' remains were puzzling, he says, because there are no records of an active penguin colony at this site.

Two groups of tiny, delicate marine organisms, sea butterflies and sea angels, were found to be surprisingly resilient -- having survived dramatic global climate change and Earth's most recent mass extinction event 66 million years ago.
Marine heatwaves are human-made
on September 25, 2020 at 3:33 pm
Heatwaves in the world's oceans have become over 20 times more frequent due to human influence. This is what researchers are now able to demonstrate. Marine heatwaves destroy ecosystems and damage fisheries.
Switching up: Marine bacteria shift between...

Researchers have found that marine bacteria exploit resource patches efficiently by switching between attached and planktonic lifestyles, and fine-tuning the time spent on patches depending on their quality. Bacteria stayed longer on higher-quality patches, as predicted by patch use theory. Future studies in this area could help to predict the role of marine bacteria in the global carbon cycle.

The severe droughts in the USA and Australia are the first sign that the tropics, and their warm temperatures, are apparently expanding in the wake of climate change.

A watershed study for wetland restoration
on September 25, 2020 at 12:08 pm
Where rivers meet oceans, each cycle of the tide moves water in and out of estuaries. The mixing and mingling of fresh and briny water, combined with seasonal weather, creates a unique environment for ecosystems in coastal estuaries and upstream tidal rivers.

Cadmium (Cd), classified as a human carcinogen, is dispersed into aquatic ecosystems mainly through industrial processes or via the application of phosphate fertilizers. The high solubility of Cd in water facilitates its wide distribution in aquatic systems, and it can be readily taken up by aquatic plants and cause phytotoxicity.

A small subpopulation of polar bears lives on what used to be thick, multiyear sea ice far above the Arctic Circle. The roughly 300 to 350 bears in Kane Basin, a frigid channel between Canada's Ellesmere Island and Greenland, make up about 1-2% of the world's polar bears.

To understand how climate change may affect different ecosystems, 27 researchers from Brazil, Argentina, Colombia, Costa Rica, French Guiana and Puerto Rico, among other countries, conducted experiments in seven different locations involving the aquatic environment in the tank (centrally-located water-holding cup) of bromeliads, a habitat for insect larvae and other small organisms.
Just add water: Biodiversity resurgence in...

Throughout the late 19th century, rivers across the southwestern United States were parceled out, and flows were diverted through irrigation canals and trapped behind dams. Growing populations put new demands on groundwater sources. Coupled with changing climate conditions, water tables sank and perennial streams began to run dry.
