The greatest depth in the Arctic Ocean is at Molloy Deep, 18,599 ft (5,669 m), in the Fram Strait N of the Greenland Sea. Arctic temperatures continue to increase at double the rate of the global temperature increase. The Chukchi Sea and eastern Baffin Bay show the largest ocean surface warming trends; August SSTs are increasing at ~0.5°C/decade in these regions. Antarctic Ocean. It has an average depth of 4000-5000 meters and touches around 17,968 kilometers of Antarctic coastline. A continental shelf about 260 kilometers wide and a maximum of 2600 kilometers lies beneath this ocean. That means at high latitudes sea ice can form.
