Sentences with phrase «deep ocean stratification»

Not exact matches

With higher levels of carbon dioxide and higher average temperatures, the oceans» surface waters warm and sea ice disappears, and the marine world will see increased stratification, intense nutrient trapping in the deep Southern Ocean (also known as the Antarctic Ocean) and nutrition starvation in the other oceans.

Stratification will reduce the return flow of both carbon and nutrients from the deep oceans to the surface.

Climate change can influence the distribution of dead zones by increasing water temperature and hence microbial activity, as well as reducing mixing of the ocean (i.e., increasing layering or stratification) of the Ocean — which have different temperatures, densities, salinities — and reducing mixing of oxygen - rich surface layers into the deeper parts of the Oocean (i.e., increasing layering or stratification) of the Ocean — which have different temperatures, densities, salinities — and reducing mixing of oxygen - rich surface layers into the deeper parts of the OOcean — which have different temperatures, densities, salinities — and reducing mixing of oxygen - rich surface layers into the deeper parts of the OceanOcean.

This study specifically considers the role of Antarctic sea ice in shaping deep ocean circulation and stratification, by driving surface buoyancy loss associated with brine rejection (when sea ice forms, salt is pushed into the surrounding seawater, making it denser).

About half of the pCO2 decrease may be due to increased glacial ocean stratification, trapping carbon - rich waters in the deep layers away from the atmosphere (22, 23).

Rather, it is likely that surface warming gradually stabilizes ocean stratification, thus reducing deep - water production at high latitudes, which acts to weaken advective heat uptake by meridional overturning circulation [cf. Meehl et al., 2011; 2013].»

The warming of the surface of the ocean is thought to increase stratification within the water column, preventing the nutrients in the cool deep ocean from rising to the surface.

Decreases in both upwelling and formation of deep water and increased stratification of the upper ocean will reduce the input of essential nutrients into the sunlit regions of oceans and reduce productivity (Cox et al., 2000; Loukos et al., 2003; Lehodey et al., 2003; Sarmiento et al., 2004a).

A quantitative theoretical model of the meridional overturning circulation and associated deep stratification in an interhemispheric, single - basin ocean with a circumpolar channel is presented.

The sea is not only warming, leading to higher stratification and thus lower ventilation of the deep ocean, it also is becoming more acidic.
