Seasonal Trends in Clouds and Radiation over the Arctic Seas from Satellite Observations during 1982 to 2019 by Xi Wang, Jian Liu, Bingyun Yang, Yansong Bao, George P. Petropoulos, Hui Liu, Bo Hu

“…The spatial distribution of the trends is nearly consistent between the cloud fraction and the surface longwave radiation, except for spring over the Chukchi and Beaufort Seas. We further obtained a significant negative correlation between cloud fraction (surface downwelling/upwelling longwave fluxes) and sea-ice concentration during autumn, which is largest in magnitude for regions with substantial sea ice retreat. …”

“…Positive late summer TCWV trends above the western Greenland and Beaufort seas (about 20%) result from enhanced upper ocean warming and thereby a local coastal decline in ice extent. …”

Exploring the Pacific Arctic Seasonal Ice Zone With Saildrone USVs by Andrew M. Chiodi, Andrew M. Chiodi, Chidong Zhang, Edward D. Cokelet, Qiong Yang, Qiong Yang, Calvin W. Mordy, Calvin W. Mordy, Chelle L. Gentemann, Chelle L. Gentemann, Jessica N. Cross, Noah Lawrence-Slavas, Christian Meinig, Michael Steele, Don E. Harrison, Phyllis J. Stabeno, Heather M. Tabisola, Heather M. Tabisola, Dongxiao Zhang, Dongxiao Zhang, Eugene F. Burger, Kevin M. O’Brien, Kevin M. O’Brien, Muyin Wang, Muyin Wang

“…To better assess the potential for arrays of uncrewed surface vehicles (USVs) to provide such observations, five wind-driven and solar-powered saildrones were sailed into the Chukchi and Beaufort Seas following the 2019 seasonal retreat of sea ice. …”

Possible Impact of Early Spring Arctic Sea Ice on Meiyu Cessation over the Yangtze–Huaihe River Basin by Jing Wang, Ning Fu, Ping Liang, Mingcai Li

“…This study observed an intimate out-of-phase relationship between MWD variations and early spring (March and April) Arctic Sea ice area (SIA) anomalies to the north of the Chukchi and Beaufort Seas, as well as SIA anomalies to the north of the Queen Elizabeth Islands (75° N–82° N, 170° E–130° W and 82° N–86° N, 130° W–80° W, respectively) on the interannual timescale. …”

Delay in Arctic Sea Ice Freeze-Up Linked to Early Summer Sea Ice Loss: Evidence from Satellite Observations by Lei Zheng, Xiao Cheng, Zhuoqi Chen, Qi Liang

“…Sea ice loss would be the key reason for the delay in autumn freeze-up, especially in the Laptev, East-Siberian, Chukchi and Beaufort Seas, where sea ice has significantly declined throughout the summer, and strong correlations were found between the freeze-up onset and the solar radiation budget since early summer. …”

Summer net community production in the northern Chukchi Sea: Comparison between 2017 and 2020 by Soyeon Kwon, Soyeon Kwon, Inhee Lee, Keyhong Park, Kyoung-Ho Cho, Jinyoung Jung, Taewook Park, Youngju Lee, Chanhyung Jeon, Chanhyung Jeon, Seongbong Seo, Doshik Hahm, Doshik Hahm

“…The net community production (NCP) estimates that we derived from O2/Ar measurements were largely in the range of 1 – 11 mmol O2 m-2 d-1 in the northern Chukchi and Beaufort Seas, close to the lower bounds of the values in the global oceans. …”

Surface and Interior Dynamics of Arctic Seas Using Surface Quasi-Geostrophic Approach by Marta Umbert, Eva De-Andrés, Rafael Gonçalves-Araujo, Marina Gutiérrez, Roshin Raj, Laurent Bertino, Carolina Gabarró, Jordi Isern-Fontanet

“…This study assesses the capability of Surface Quasi-Geostrophy (SQG) to reconstruct the three-dimensional (3D) dynamics in four critical areas of the Arctic Ocean: the Nordic, Barents, East Siberian, and Beaufort Seas. We first reconstruct the upper ocean dynamics from TOPAZ4 reanalysis of sea surface height (SSH), surface buoyancy (SSB), and surface velocities (SSV) and validate the results with the geostrophic and total TOPAZ4 velocities. …”

Changes in the Arctic Ocean CO by Menemenlis, D., Key, R. M., Manizza, Manfredi, Follows, Michael J, Dutkiewicz, Stephanie, Hill, Christopher N.

“…A regional analysis suggests that during the 1996-2007 period, the shelf regions of the Laptev, East Siberian, Chukchi, and Beaufort Seas experienced an increase in the efficiency of their biological pump due to decreased sea ice area, especially during the 2004-2007 period, consistent with independently published estimates of primary production. …”

Migratory culture, population structure and stock identity in North Pacific beluga whales (Delphinapterus leucas). by Greg O'Corry-Crowe, Robert Suydam, Lori Quakenbush, Brooke Potgieter, Lois Harwood, Dennis Litovka, Tatiana Ferrer, John Citta, Vladimir Burkanov, Kathy Frost, Barbara Mahoney

“…Using a much expanded sample and genetic marker set comprising 1,647 whales, spanning more than two decades and encompassing all major coastal summering aggregations in the Pacific Ocean, we found evolutionary-level divergence among three geographic regions: the Gulf of Alaska, the Bering-Chukchi-Beaufort Seas, and the Sea of Okhotsk (Φst = 0.11-0.32, Rst = 0.09-0.13), and likely demographic independence of (Fst-mtDNA = 0.02-0.66), and in many cases limited gene flow (Fst-nDNA = 0.0-0.02; K = 5-6) among, summering groups within regions. …”

Benefits of sea ice initialization for the interannual-to-decadal climate prediction skill in the Arctic in EC-Earth3 by T. Tian, S. Yang, M. P. Karami, F. Massonnet, T. Kruschke, T. Koenigk, T. Koenigk

“…East Siberian and Beaufort seas) in the first few lead years. Our results suggest that as the climate warming continues and the central Arctic Ocean might become seasonal ice free in the future, the controlling mechanism for decadal predictability may thus shift from sea ice volume to ocean-driven processes.…”

Variability in Benthic Ecosystem Functioning in Arctic Shelf and Deep-Sea Sediments: Assessments by Benthic Oxygen Uptake Rates and Environmental Drivers by Joshua Kiesel, Christina Bienhold, Christina Bienhold, Frank Wenzhöfer, Frank Wenzhöfer, Heike Link

“…Pan-Arctic regional comparisons were obtained by extending our analyses to previously published data from the Laptev and Beaufort Seas. Our results show that (1) benthic oxygen uptake rates and most environmental predictors varied significantly between shelf and deep-sea habitats; (2) the availability of detrital organic matter is the main driver for patterns in total as well as diffusive respiration, while bacterial abundances were highly variable and only a weak predictor of differences in TOU and DOU; (3) regional differences in oxygen uptake across shelf and deep-sea sediments were mainly related to organic matter availability and may reflect varying primary production regimes and distances to the nearest shelf. …”

Interdecadal Linkage Between the Winter Northern Hemisphere Climate and Arctic Sea Ice of Diverse Location and Seasonality by Xulong He, Ruonan Zhang, Ruonan Zhang, Ruonan Zhang, Shuoyi Ding, Zhiyan Zuo

“…Four critical sea-ice subregions are analyzed in this study—namely, the Pan-Arctic, Barents–Kara–Laptev Seas (BKL), East Siberia–Chukchi–Beaufort Seas (EsCB), and Bering Sea (Ber). Results suggest that interdecadal reduction of autumn sea-ice, irrespective of geographical location, is dynamically associated with the negative phase of the North Atlantic Oscillation (NAO) in the subsequent winter via stratospheric pathways. …”
