If the recent intensification of the cool spot were caused by a recent AMOC slowdown you would expect to see warming of intermediate waters under a cool fresh water surface layer.

The linkage between intermediate - water warming and gas hydrate destabilization could provide an important feedback in the establishment of peak PETM warmth.»

In an ensemble of fully coupled atmosphere - ocean general circulation model (AOGCM) simulations of the late Paleocene and early Eocene, we identify such a circulation - driven enhanced intermediate - water warming.

An abrupt warming of oceanic intermediate waters could have initiated the thermal destabilization of sediment - hosted methane gas hydrates and potentially triggered sediment slumps and slides.

The best time of the year to go surfing in Wilmington is usually during the winter swells for advanced and intermediate - level riders; however, summer - time waves are perfect for beginners with mainly consistent, warm - water waves.

If this is so, warming will proceed at a slower rate until these intermediate waters are brought to a temperature at which they can no longer absorb heat.

In this model, enhanced seasonal contrasts through milankovitch forcing (Lourens et al., 2005), combined with a gradually warming late - Paleocene to early Eocene, forced a non-linear response in ocean circulation to warm intermediate waters.

The results suggest that warm Atlantic water never ceased to flow into the Nordic seas during the glacial period; inflow at the surface during the Holocene and warm interstadials changed to subsurface and intermediate inflow during cold stadials.

Contributions of Warm Saline Deep Water (WSDW) diminished, and the influential Antarctic Intermediate Water (AAIW) was increasingly cooled by much colder Antarctic Bottom Water.

We show that water masses linked to North Pacific and Antarctic intermediate waters were warmer by 2.1 ± 0.4 °C and 1.5 ± 0.4 °C, respectively, during the middle Holocene Thermal Maximum than over the past century.

This makes it clear to what extent the variability in the inflow of «warm and salty» North Atlantic water at times of positive values of the NAO (North Atlantic Oscillation) dominates the temperature of the Atlantic water mass by importing «vast quantities of heat» into the Arctic Ocean to induce core temperatures in the intermediate layer in Nansen Basin that are much warmer than in the Canadian Basin, far downstream.

Observations and numerical modeling reveal large fluctuations in the ocean heat available in the adjacent bay and enhanced sensitivity of ice - shelf melting to water temperatures at intermediate depth, as a seabed ridge blocks the deepest and warmest waters from reaching the thickest ice.

Holland has found circumstantial evidence that the last prolonged negative phase in the 1920s also sent warm intermediate water towards western Greenland.

Holland and his colleagues have proposed that the influx of warm intermediate water around Greenland may be tied to a complex climate phenomenon called the North Atlantic Oscillation (NAO).

Or like in the North Atlantic, the increase in westerly winds may simply be part of a cyclical process that periodically sends warm intermediate water towards Antarctica.

What is more, the water there would not be particularly warm, so it is quite possible for it to warm the deep oceans while having little influence on the intermediate regions.

With the use of a climate model of intermediate complexity, we demonstrate that with mwp - 1A originating from the Antarctic Ice Sheet, consistent with recent sea - level fingerprinting inferences, the strength of North Atlantic Deep Water (NADW) formation increases, thereby warming the North Atlantic region and providing an explanation for the onset of the Bølling - Allerød warm interval.

http://science.sciencemag.org/content/342/6158/617.abstract We show that water masses linked to North Pacific and Antarctic intermediate waters [0 - 700 m] were warmer by 2.1 ± 0.4 °C and 1.5 ± 0.4 °C, respectively, during the middle Holocene Thermal Maximum than over the past century.
