-**Status and Trends**: The cold pool extent has increased since 2018, yet the 2021 extent (58,975 km^2^) was the fourth lowest on record and remains more than one standard deviation below the grand mean of the time series (Figure 1). Estimates of cold pool area from 2018 and 2019 were the smallest on record, followed by 2003, which was only slightly small than in 2021. As is typical when the extent is small, the cold pool was restricted to the northern edge of the eastern Bering Sea shelf bottom trawl survey area (Figure 2). In general, the spatial extents of isotherms at all thresholds $\leq$ 1°C were similar, if slightly greater than prior record lows (Figure 2).  The coldest bottom temperatures were restricted to the far northwest corner of the eastern Bering Sea shelf survey area, where temperatures were greater than -1°C, with an extremely small extent of waters $\leq$ 1°C (14,925 km^2^) and $\leq$ 0°C (4,800 km^2^). However, cooler bottom temperatures were observed in the northern Bering Sea, including a substantial area with bottom temperatures $\leq$ -1°C along the U.S.-Russia convention line to the west-southwest of St. Lawrence Island, while extremely warm bottom temperatures were observed on the northern inner shelf from Norton Sound to Nunivak Island (Figure 3). The temperature difference between the inner shelf in the NBS and inner shelf in the EBS is partially due to seasonal thermal heating owing to the the NBS inner shelf being the last area sampled by the survey.

 Mean surface and bottom temperatures were cooler than in the prior survey year (2019) on the shelf of the eastern and northern Bering Sea  (Figure 4). In 2021, the mean bottom temperature in the eastern Bering Sea was 3.3°C, the fifth highest on record after 2019, 2018, and 2017, and 0.9°C above the grand mean of the time series (2.5°C). The 2021 mean surface temperature was 7.2°C, which was 2.0°C lower than in 2019 yet 0.5°C higher than the grand mean of the time series (6.7°C).
