April 27, 2023 - Sea Ice Swirls in the Labrador Sea

Sea Ice Swirls in the Labrador Sea

Swirls of sea ice painted a fanciful canopy atop a portion of the Labrador Sea in late April 2023. The Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Aqua satellite acquired a true-color image of the gorgeous scene on April 25.

The swirling and curling raft of floating ice hugs the northeastern coast of the Canadian province of Newfoundland and Labrador. A small amount of fast ice remains attached to the coastline.

According to the United States Coast Guard (USCG) International Ice Patrol (IIP) on April 20, medium to thick, first-year sea ice was compressed along the Labrador Coast in concentrations above 90 percent. Recent onshore winds, consistent with the currently negative North Atlantic Oscillation Index was reported to have kept the ice pack constrained onshore. Surface air temperatures were below normal in April, and are expected to remain cold through the rest of the month. The IIP estimates that there were two hundred and sixty icebergs floating in this general region on that date.
