Aquarius is located under 20 m (66 ft) of water at the base of a coral reef within the Florida Keys National Marine Sanctuary, an ideal site for studying the health of sensitive coral reefs. The laboratory is most often used by marine biologists for whom Aquarius acts as home base as they study the coral reef, the fish and aquatic plants that ...

The largest ocean-based source of plastic pollution is discarded fishing gear (including traps and nets), estimated to be up to 90% of plastic debris in some areas. [56] [57] Continental plastic litter enters the ocean largely through storm-water runoff, flowing into watercourses or directly discharged into coastal waters. [58]
The surface salinity of the ocean is a key variable in the climate system when studying the global water cycle, ocean–atmosphere exchanges and ocean circulation, all vital components transporting heat, momentum, carbon and nutrients around the world. [84] Cold water is more dense than warm water and salty water is more dense than freshwater.
With primary causes being warming ocean waters, ocean acidity, and pollution. [149] In 2008, a worldwide study estimated that 19% of the existing area of coral reefs had already been lost. [ 150 ] Only 46% of the world's reefs could be currently regarded as in good health [ 150 ] and about 60% of the world's reefs may be at risk due to ...
In the 1970s and '80s, most lab-based tests were “lower risk, small volume” products used mostly for local patients, the FDA noted Friday. Over time, laboratory-developed tests have grown into ...
The types of marine pollution can be grouped as pollution from marine debris, plastic pollution, including microplastics, ocean acidification, nutrient pollution, toxins and underwater noise. Plastic pollution in the ocean is a type of marine pollution by plastics , ranging in size from large original material such as bottles and bags, down to ...
The FDA has its own requirements for animal research, known as Good Laboratory Practice, to demonstrate that any scientific data being collected in the development of a drug or medical device is ...
