While many sources of stress have caused corals to bleach, «mass» coral bleaching (at scales of 100 km or more) has only occurred when anomalously warm ocean temperatures, typically coupled with high subsurface light levels, exceeded corals» physiological tolerances.
It is further shown that the warm phase of the AMO corresponds to a strengthening of the Atlantic meridional overturning circulation (AMOC) and a weakening of the Atlantic subtropical cell (STC), which both induce an anomalous northward current in the TNA subsurface ocean.
«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»
Because the mean meridional temperature gradient of the subsurface ocean is positive because of the temperature dome around 9 ° N, the advection by the anomalous northward current cools the TNA subsurface ocean during the warm phase of the AMO.
The feedbacks, including subsurface ocean warming, help explain paleoclimate data and point to a dominant Southern Ocean role in controlling atmospheric CO2, which in turn exercised tight control on global temperature and sea locean warming, help explain paleoclimate data and point to a dominant Southern Ocean role in controlling atmospheric CO2, which in turn exercised tight control on global temperature and sea lOcean role in controlling atmospheric CO2, which in turn exercised tight control on global temperature and sea level.
report that ocean sediment cores containing an «undisturbed history of the past» have been analyzed for variations in PP over timescales that include the Little Ice Age... they determined that during the LIA the ocean off Peru had «low PP, diatoms and fish,» but that «at the end of the LIA, this condition changed abruptly to the low subsurface oxygen, eutrophic upwelling ecosystem that today produces more fish than any region of the world's oceans... write that «in coastal environments, PP, diatoms and fish and their associated predators are predicted to decrease and the microbial food web to increase under global warming scenarios,» citing Ito et al..
Meltwater tends to stabilize the ocean column, inducing amplifying feedbacks that increase subsurface ocean warming and ice shelf melting.
The upper 3 meters of the world's oceans hold more heat than the entire atmosphere, so continual ventilation of just 10 meters of warmer subsurface water will affect the global average for decades.
Subsurface ocean warming explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at the Earth's surface.
The strong warming of the subsurface ocean is a testament to this.
Warming of surface ocean waters is well known, but how the subsurface waters are changing is less clear.
Based on a conceptual oceanographic model, the researchers propose a mechanism for the subsurface warming of the glacial Arctic Ocean: A reduced influx of freshwater to the Arctic Ocean acted to deepen the halocline and push the warm Atlantic Layer downward.
The new study published as a Letter in Nature Geoscience shows that the warm intermediate Atlantic Layer was displaced far downward in the glacial Arctic Ocean, resulting in a substantial warming at depths between 1000 and 2500 m. Based on a conceptual oceanographic model, the researchers propose a mechanism for the subsurface warming of the glacial Arctic Ocean: A reduced influx of freshwater to the Arctic Ocean acted to deepen the halocline and push the warm Atlantic Layer downward.

Reduced equatorial cloud cover during La Nina (due to the cooler sea surface temperature), combined with the strong upwelling (Ekman suction) in the eastern equatorial Pacific, does indeed lead to greater warming of the ocean - because it's bringing cool subsurface water to the surface, where it can be heated by the sun.
... then why do the vertical mean temperature anomalies (NODC 0 - 2000 meter data) of the Pacific Ocean as a whole and of the North Atlantic fail to show any warming over the past decade, a period when ARGO floats have measured subsurface temperatures, providing reasonably complete coverage of the global oceans?
Thus, the static stability of the near - surface water increases and the convective mixing of cold surface water with the relatively warm subsurface water is reduced, thereby contributing to the reduction of sea surface temperature in the Circumpolar Ocean.
