Human Interaction and Disturbance of Denning Polar Bears on Alaska's North Slope.  Across the central coast of Alaska's North Slope, human-polar bear interactions concern both industry and wildlife managers alike. In response to sea ice reductions due to climate change, parturient polar bears (Ursus maritimus) in the Southern Beaufort Sea subpopulation are increasingly accessing coastal topography for suitable denning habitat. Land-denning bears are more susceptible to anthropogenic stressors, chiefly in areas with high levels of energy exploration, extraction, and production. For over 30 years, denning polar bears in the Southern Beaufort Sea subpopulation have been monitored directly or through opportunistic observations.

Changes in Phytoplankton Concentration Now Drive Increased Arctic Ocean Primary Production. Historically, sea ice loss in the Arctic Ocean has promoted increased phytoplankton primary production because of the greater open water area and a longer growing season. However, debate remains about whether primary production will continue to rise should sea ice decline further. Using an ocean color algorithm parameterized for the Arctic Ocean, we show that primary production increased by 57% between 1998 and 2018. Surprisingly, whereas increases were due to widespread sea ice loss during the first decade, the subsequent rise in primary production was driven primarily by increased phytoplankton biomass, which was likely sustained by an influx of new nutrients. This suggests a future Arctic Ocean that can support higher trophic-level production and additional carbon export.

The COVID-19 Pandemic Has Halted Most US Arctic Field Research for 2020. The COVID-19 Pandemic Has Halted Most US Arctic Field Research for 2020. Seasonal scientific field work in the Arctic - from the Toolik Field Station on Alaska's North Slope to ice core drilling in Greenland - is being postponed or cancelled this year because of the deadly COVID-19 pandemic. Researchers hope that by putting off travel to the region, they will avoid spreading the disease in vulnerable rural communities and in field outposts with close living and working quarters. But the disruption will hinder a wide variety of ongoing studies, including research on ice sheets, glaciers, permafrost, plant and animal habitats, and ocean fisheries - research that underpins human understanding of global climate change and other vital scientific questions in the circumpolar North.

Siberian Heat Streak and Arctic Temperature Record Virtually 'Impossible' Without Global Warming, Study Says. In a stark new finding, a study shows that six straight months of anomalously mild conditions in large parts of northern Siberia so far this year, along with an Arctic temperature record of 100.4 degrees (38 Celsius) that occurred in June, would have been virtually impossible without human-induced global warming. The study, released Wednesday by the World Weather Attribution project, was produced through a collaboration between climate researchers from multiple institutions in France, Germany, the Netherlands, Russia, Switzerland and the United Kingdom.

Seeking Co-Leads and Shared Resources for the IARPC Diversity and Inclusion Team. Given the events of the past weeks, the leadership of the IARPC Diversity and Inclusion team has been discussing concrete steps on how we can best support the Arctic research community, and more specifically our Black and Indigenous colleagues, during this time. The leadership of the IARPC Diversity and Inclusion Team consists of no Black or Indigenous members. We want to ensure that all those in Arctic research and policy are the ones doing the work to move forward efforts on inclusivity and equity in Arctic research. That being said, we acknowledge that as much as we read, see, and listen to the experiences of our Black and Indigenous colleagues, those of us without those identities will never fully understand the experience of being Black and/or Indigenous in Arctic research.

China's Polar Icebreaker Sets Sail for Arctic. Chinese scientists set off for the 11th Arctic expedition Wednesday aboard Xuelong 2, the country's first domestically built polar icebreaker, departing from Shanghai. It is the first scientific expedition to the Arctic for Xuelong 2, or Snow Dragon 2, after it completed its first Antarctica expedition in April. It is expected to return to Shanghai in late September after a trip of 12,000 nautical miles. China.org.cn
 
Pompeo to Talk Arctic at Upcoming Meeting With Danish FM. The Arctic will be high on the agenda when U.S. Secretary of State Mike Pompeo travels to Copenhagen at the end of the month. While there, Pompeo will meet with Danish Foreign Minister Jeppe Kofod, Greenlandic Foreign Minister Steen Lynge and the Faroe Islands' national board member for foreign affairs Jenis av Rana. "Since we also have to discuss Arctic issues, my colleagues from Greenland and the Faroe Islands must of course also sit at the table," said Kofod in a news release posted Wednesday on the Danish Foreign Ministry's website announcing the July 22 meeting.  Radio Canada International
   
The Disappearance of Arctic Sea Ice Due to Climate Change Could Lead to Increased Ocean Noise. The Bering Strait is a vital migration route for numerous marine species. Scientists examining levels of ocean noise in the area have confirmed that the presence of sea ice plays a central role in the soundscape of these Arctic waters. Arctic species such as bowhead whales, belugas, walrus, bearded seals and ribbon seals are seasonally present in and travel through the waters around St. Lawrence Island and the Bering Strait.

Save the Date: 2nd Symposium on Polar Microbes and Viruses, May 3-6, 2021 (Hanko, Finland). Organizers announce, that due to the coronavirus outbreak, the 2nd Symposium on Polar Microbes and Viruses has been postponed to 2021. This symposium will bring together molecular microbial ecologists specializing in different organism groups to share our latest results and discuss methodological problems, as well as future prospects in the field, including practical international collaborations. The environmental focus will be on cryospheric environments including sea ice, glaciers, ice sheets, and permafrost, but excellent research in other polar environments is also invited. The methods to be discussed will focus on 'omics' techniques, ranging from single cells to metagenomes, but research using additional methods is encouraged as well.

update on schedule... 3rd Arctic Science Ministerial, May 8-9, 2021 (Toyko, Japan).  The Japanese and Icelandic organizers of this ministerial continue to plan for an in-person ministerial, in Tokyo, but have moved the dates from November 21-22, 2020 to May 8-9, 2021 because of Covid-19. Since the last Arctic Science Ministerial in 2018, changes in the Arctic ecosystem and the resulting impacts locally and globally have been severely felt. Considering the need for climate change mitigation, adaptation, and repair measures, the relevance of an international Arctic Science Ministerial has never been greater. It is necessary to strengthen scientific cooperation and collaboration among both Arctic and non-Arctic States in order to develop our understanding of the rapid changes impacting the Arctic. The First Arctic Science Ministerial (ASM1) was hosted by the United States in 2016, and two years later, the Second Arctic Science Ministerial (ASM2) was co-hosted by Germany, Finland, and the European Commission. ASM3 will be co-hosted by Iceland and Japan.
