Sentences with phrase «lowers ocean salinity»

But the influx of cold fresh water from melting icebergs then lowers the ocean salinity and cools surface temperatures, allowing the surface to freeze more easily.

Melting of either floating ice or glaciers and ice sheets lowers ocean salinity.»

Not exact matches

As to the salinity question, the NOAA research ships had noted in earlier cruises that for the ice melt the salinity though lower then normal for open ocean demonstrate only a thin fresh / brackish water zone.

The salinity levels of the northern ocean region are also influence by the inflow of warm and salty water from lower latitudes in the Atlantic Oocean region are also influence by the inflow of warm and salty water from lower latitudes in the Atlantic OceanOcean.

Human activity and CO2 has a general meaning, having to do with conductivity meanings in the oceans, particularly a signal in lower salinity zones in the oceans, where the relative ion count increases.

Between this lower salinity layer and the bulk of the ocean lies the so - called halocline, in which both salinity and temperature are rising with increasing depth.

The system can weaken or shut down entirely if the North Atlantic surface - water salinity somehow drops too low to allow the formation of deep - ocean water masses.

In large parts of the Arctic Ocean, the top layer (about 50 m (160 ft)-RRB- is of lower salinity and lower temperature than the rest.

The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.

El Ni o an irregular variation of ocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fiocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fiOcean, having disastrous effects on marine life and fishing

The key to this model lies in the distribution of precipitation on Earth, with maxima in the tropics and in high latitudes, so that the Arctic receives an excess of precipitation over evaporation of about one third, which is associated with the permanent presence of the low salinity surface water mass of the Arctic Ocean, separated by a halocline from the saltier Atlantic water below.

The flow of freshwater from the northern continents represents an export to the world ocean that goes almost entirely into the Atlantic, about 5.1 Sv passing as relatively low salinity water through the passages between Greenland and Ellesmere Island into the Labrador Sea, a flow of low salinity water that can subsequently be traced around the subpolar gyre.

These indicators include greenhouse gas concentrations, temperature of the lower and upper atmosphere, cloud cover, sea surface temperature, sea - level rise, ocean salinity, sea ice extent and snow cover.

It emphasises that there is a strong internal relationship between the formation, stability and extent of sea ‐ ice and the structure of the upper layer of the Arctic ocean: it is the relative area and depth of low - salinity arctic water above the halocline that are paramount to ice formation and its summer survival.

Haloclines are formed by summer melt water which is lower in salinity than the ocean and spreads over the surface as it can not penetrate the less dense, low salinity Arctic sea water.

This fresh water, together with melt ‐ water from the melting ice pack in summer forms a permanent superficial layer (usually about 200m deep) of low salinity over the entire Arctic Ocean, without which much less seasonal ice would form.

In this paper, it is shown that coherent large - scale low - frequency variabilities in the North Atlantic Ocean — that is, the variations of thermohaline circulation, deep western boundary current, northern recirculation gyre, and Gulf Stream path — are associated with high - latitude oceanic Great Salinity Anomaly events.
