Researchers from the neatly monikered Institute of Low Temperature Science at Hokkaido University in Sapporo, Japan are showing that intermediate water (200-2000m) off Russia has warmed significantly over the past 50 years. The warming trend is accompanied by decreasing oxygen content. The warmer water is attributed to a decrease in (cold) shelf water production in the Sea of Okhotsk, an epicenter of global warming.
Monterey Bay Aquarium Research Institute (MBARI) scientists working in the Arctic Ocean unraveled the geological origin of many mysterious mounds, called “pingos”, off Canada’s north coast. Pingos are small, dome-shaped, ice-cored hills about 40m tall, found along the coast of the Tuktoyaktuk Peninsula. Earlier studies claimed these features were formed on land, and then submerged when sea level rose following the end of the last ice age, over 10,000 years ago. Apparently, the reverse may be true.
