Sentences with phrase «as ocean stratification»

If this apparent transformation continues, it may lead to a markedly different ice regime in the Arctic, altering heat and mass exchanges as well as 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.

One group of researchers favors «stratification» as a cause — the tendency of climate warming of the upper ocean to restrict seasonal overturning and reduce the supply of new atmospheric oxygen.

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.

While it is tempting to attribute the unexplained sea ice trends to other factors such as increased upwelling of relatively warm circumpolar deepwater (Thoma et al. 2008), an intensification of the hydrological cycle and increased ocean stratification (Liu and Curry 2010), or eastward propagation of sea ice anomalies (Holland et al. 2005), the observed northerly wind trends (Fig. 5a) are qualitatively consistent with the decrease in sea ice in the 30 ° W — 60 ° W sector.

Middle panels: ocean stratification, as shown by potential density contours, along an Atlantic cross section at 26 ° W; notably, LGM stratification is enhanced.

As in later eras, Cretaceous warmth led to ocean stratification and anoxia; evidence shows many warm «spikes» accompanied by such anoxic episodes.

Increased stratification as the ocean surface warms will decrease the upwellings of nutrient - rich cold water, making oceans less productive.
