Aegean Sea Intermediate Water – Aegean Sea Intermediate Water extends from 40–50 m (130–160 ft) to 200–300 m (660–980 ft) with temperatures ranging from 11–18 °C (52–64 °F). Aegean Sea Bottom Water – occurring at depths below 500–1,000 m (1,600–3,300 ft) with a very uniform temperature (13–14 °C (55–57 °F)) and ...
Near the poles, cool air sinks, but is warmed and rises as it then travels along the surface equatorward. The sinking and upwelling that occur in lower latitudes, and the driving force of the winds on surface water, mean the ocean currents circulate water throughout the entire sea.
Increasing salinity lowers the freezing point of seawater, so cold liquid brine is formed in inclusions within a honeycomb of ice. The brine progressively melts the ice just beneath it, eventually dripping out of the ice matrix and sinking. This process is known as brine rejection. The resulting Antarctic bottom water sinks and flows north and ...
Ocean stratification is the natural separation of an ocean's water into horizontal layers by density.This is generally stable stratification, because warm water floats on top of cold water, and heating is mostly from the sun, which reinforces that arrangement.
It gives the water an appearance of wrinkled glass, the kind often used in bathroom windows to obscure the view, and is caused by the altered refractive index of the cold or warm water column. These same schlieren can be observed when hot air rises off the tarmac at airports or desert roads and is the cause of mirages.
A magnitude 7.0 earthquake in the Aegean Sea rattled parts of Greece and Turkey on Friday, the U.S. Geological Survey (USGS) said. The Associated Press, citing Turkey's interior minister, reported ...
Warm air rises near the equator. Later, as it moves toward the poles, it cools again. Cool air sinks near the poles, but warms and rises again as it moves toward the equator. This produces Hadley cells, which are large-scale wind patterns, with similar effects driving a mid-latitude cell in each hemisphere.
The possible effects of climate change are far worse, and could strike far sooner, than we previously thought, according to Dr. James Hansen, a leading climate change researcher who was among the ...
