USGS released an important study of the deep ocean’s temperature variability and circulation system .According t this study the deep ocean is apparently affected more by surface warming than previously thought, and this understanding allows for more accurate predictions of factors such as sea level rise and ice volume changes.Higher ocean surface temperatures have been found to result in a more vigorous deep ocean circulation system. This increase results in a faster transport of large quantities of warm water, with possible impacts including reduction of sea ice extent and overall warming of the Arctic.
