Bottom water by an estuary of a river discharging into a saline body exhibits peculiar transport of mud.Due to fresh/saline water intermixing by the estuary, a horizontal isohale gradient is created, with lower salinity levels upstream, which generates the upstream flow of the bottom water.
The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and ...
a small, discrete body of water held by some plants. Plunge pool: a depression at the base of a waterfall. Pool: various small bodies of water such as a swimming pool, reflecting pool, pond, or puddle. Pond: a body of water smaller than a lake, especially those of artificial origin. Port
The technical distinction between a pond and a lake has not been universally standardized. Limnologists and freshwater biologists have proposed formal definitions for pond, in part to include 'bodies of water where light penetrates to the bottom of the waterbody', 'bodies of water shallow enough for rooted water plants to grow throughout', and 'bodies of water which lack wave action on the ...
The depth of water, temperature and salinity, and type of local substrate all affect what benthos is present. In coastal waters and other places where light reaches the bottom, benthic photosynthesizing diatoms can proliferate. Filter feeders, such as sponges and bivalves, dominate hard, sandy bottoms.
Water weight, also known as water retention, is a buildup of excess water or fluid in the body's tissues, which can occur for a variety of reasons, Dr. Felice Schnoll-Sussman, gastroenterologist ...
TIL In 1941, prior to widespread fluoridation of drinking water, almost 10% of US military recruits were rejected because they didn’t have 6 opposing teeth in their upper and lower jaws Image ...
Some chemolithotrophs can also facilitate the oxidation of hydrogen sulfide into elemental sulfur, according to the following chemical equation: [14] H 2 S + O 2 → S + H 2 O 2. Anoxia is quite common in muddy ocean bottoms where there are both high amounts of organic matter and low levels of inflow of oxygenated water through the sediment.
