The researchers found that during glacial periods when the atmosphere was colder and sea ice was far more extensive, deep ocean waters came to the surface much further north of the Antarctic continent than they do today.
«It is widely thought that during cold periods of the last Ice Age the warm Atlantic water had stopped its flow into the Nordic Seas.
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.
During the last glacial period, sea level dropped 400 feet as water was tied up in ice, and as we have moved out of the cold glacial period, sea level has recovered.
The rate of sea level rise slowed between 14,000 and 12,000 years ago during the Younger Dryas cold period and was succeeded by another surge, «meltwater pulse 1B», 11,500 - 11,000 years ago, when sea level may have jumped by 28 m according to Fairbanks, although subsequent studies indicate it may have been much less.
If there was actually glaciation during cold periods, glacial dust might well have blown out to sea, fertilizing large areas and producing a stronger CO2 pump.
As I said earlier, it would make sense for sea levels to rise quickly following a cold period like the LIA - the glaciers that quickly expanded during that time would just as quickly melt away.
In a 2009 study, the authors used GPS measurement to correct for local vertical movement of the Earth at key tide gages, finding a «global rate of geocentric sea level rise of 1.61 ± 0.19 mm / yr over the past century» Their study shows no acceleration and no changes in rate during warm or cold periods of the last 110 years.
For the sea star's buffer to work, the ocean water must be sufficiently cold during periods of high tide.
