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

Key factors in how some algae harness solar energy
on August 13, 2019 at 5:42 pm
Scientists have discovered how diatoms -- a type of alga that produce 20 percent of the Earth's oxygen -- harness solar energy for photosynthesis. The discovery could help lead to more efficient and affordable algae-based biofuels and combat climate change from fossil fuel burning.

on August 14, 2019 at 12:10 pm
Rivers in Europe are so congested with concrete obstructions like weirs, bridges and other man-made barriers that they no longer flow freely, which harms the wider environment. Removing these blockages could restore these vital aquatic ecosystems to their former glory.
