MISSING ICE Cameras, like this one, set up in the Chukchi and Bering seas, record how much light reaches through the melt ponds that sit atop sea ice. More light means more algal blooms grow below the surface. K. FREY
‘Record low sea ice in 2018 sent ripples through the entire Arctic ecosystem’
“There were early signs that conditions in 2017 and 2018 were going to be different. By November 2017, the sea ice was already late. The air above the waves wasn’t especially warm. In fact, the air temperature was typical for that time of year, Phyllis Stabeno, a physical oceanographer at the National Oceanic and Atmospheric Administration’s Pacific Marine Environmental Laboratory in Seattle, reported at the December meeting. But an unusually persistent wind was blowing from the south, she said, preventing the ice from drifting down from the Chukchi Sea as it would normally.
The wind tapered off by December and January, but by then air temperatures were higher than normal. The Chukchi Sea, normally at least 80 percent covered by thick, tough, icebreaker-testing pack ice by January, still had large open swaths of water. That meant less ice was available to migrate southward through the Bering Strait.” – Carolyn Gramling, 2014. Read the full article here.
