An image from space of the Great Lakes from NOAA’s GOES-16 satellite on January 20, 2020. What's missing from the Great Lakes in this image? Ice. Looking through the cloud cover you can see that ice coverage of the Lakes was well below what is expected for this time of the year. (2020 image).

Arctic melt season puts focus on sea ice forecasts

The German icebreaker Polarstern travels through Arctic sea ice in August 2020 as melt ponds are forming. The Polarstern has been in the Arctic Ocean since September 2019, supporting the international MOSAiC mission to better understand the region’s climate system and its influence on the rest of the world.

Arctic sea ice reached its annual high on March 5

Arctic Ocean sea ice hit its annual peak for this year on March 5, 2020: This color-coded map shows Arctic sea ice concentration on March 5, 2020. Darkest blue indicates open water or ice concentration less than 15 percent. Shades of lighter blue to white indicate 15–100 percent ice cover. The gold line shows the median ice extent for this date over 1981–2010, an area of 6.04 million square miles (15.64 million square kilometers). Median falls “in the middle” because half of the years in the 1981–2010 reference period had larger extents, and half had smaller extents.

Anticipating more activity in the Arctic, NOAA invests in research to advance sea ice forecasting

Responding to oil spills in the ice-covered Arctic Ocean would pose unique challenges. For example, floating booms often used to concentrate oil for burning — as in this field experiment in the Barents Sea — must be strong enough to handle increased drag from ice floes. (Undated image.)
