The Chukchi Sea is directly north of the Bering Strait. Choice excerpt, spacing added:
>We also suggested a possible role of a strong oceanic heat inflow to the Chukchi Sea via Bering Strait.
>In support of this view, in the summer of 2017, Rebecca Woodgate of the University of Washington, Seattle, sailing on the research vessel Norseman II, recovered mooring data that indicated an early arrival of warm ocean water in the strait, about a month earlier than the average. This resulted in June ocean temperatures that were 3 degrees Celsius (5 degrees Fahrenheit) above average.
>Higher ocean temperatures in summer plays a large role in the timing of when the ice will form again in winter. There is likely a considerable amount of heat remaining in the top layer of the ocean, which will need to be lost to the atmosphere and outer space before the region becomes fully ice covered.
Just a reminder: When floating ice melts in water the level of the water does not rise. https://www.youtube.com/watch?v=aOCqHRpQh88
