Arctic landscapes are responding to climate change, however long-term observation sites focused on landscape and ecosystem changes in the Arctic are extremely limited. For the past 12 years Ben Jones, University of Alaska Fairbanks, and colleagues have re-established the Teshekpuk research station in northern Alaska to address this need. They have combined renovation efforts with active and diverse research projects funded primarily by the National Science Foundation, U.S. Geological Survey (USGS), Bureau of Land Management, European Space Agency, and European Union.

The sky is routinely overlooked in Northern Dene (Athabaskan) ethnology as a meaningful site for investigating linguistic and cultural knowledge. The central research question of this study asked: How do Northern Dene peoples perceive, conceptualize, and integrate the sky and its contents into systems of knowledge and worldview? Results have shown that systems of stellar knowledge are especially complex and detailed.

Thaw of permafrost containing high concentrations of ground ice can dramatically impact Arctic environments through resulting thermokarst features. Once exposed to melt, retrogressive thaw slumps, the most important type of thermokarst landform on sloping terrain, may reactivate every summer for up to 50 years—altering water quality and aquatic ecosystems, and liberating frozen organic carbon for subsequent decomposition, thereby contributing to the permafrost carbon feedback.

A recent study by Alaska NSF Established Program to Stimulate Competitive Research (EPSCoR) examined the capacity of different Northern communities to adapt to change. A key element of the project was directly engaging with community stakeholders to help shape the direction of the research, and to ensure that research outcomes met local needs. The subsequent report, "Sharing Questions, Sharing Answers" details strategies used by different parts of the project to engage stakeholders, and lessons learned along the way.

The socio-ecological consequences of changes in the Arctic environmental system extend far beyond the Arctic, and international collaboration is essential to address the challenges arising from a warming Arctic. Scientists are very effective in international scientific collaboration, developing research-driven joint projects and programs from the bottom up. The Arctic Science Ministerials, where governments of Arctic and non-Arctic states are making commitments that provide high-level political and policy support for the scientists' grass-roots efforts, are an important addition to the landscape of Arctic scientific collaboration and the development of Arctic science diplomacy.

Unusually low Arctic sea ice conditions in the winter of 2017 brought to the forefront questions about what the impacts of low sea ice would mean for the communities and ecosystems in the Bering Sea.
The Sea Ice for Walrus Outlook (SIWO) program, a long-term collaborative effort between academic and federal researchers, ARCUS, the Eskimo Walrus Commission, and coastal subsistence hunters in the Bering Strait region, was poised to provide some answers about how Pacific walruses migrating north in spring might respond to low ice conditions.

The Arctic is in the midst of an unprecedented environmental transition caused by increasing land and ocean temperatures. Arctic sea ice is rapidly decreasing and, with little sea ice, Alaska Native coastal communities have limited protection from storm surges. In the United States, no institutional framework currently exists to determine whether and when relocation needs to occur in order to protect people from environmental hazards. Inspired by usteq, the Yup'ik word for catastrophic land collapse, the Alaska Institute for Justice is working with 15 Alaska Native communities to address this institutional gap.

Funded by the National Science Foundation, the Sitka Sound Science Center's Scientist in Residency Fellowship (SIRF) program is designed to help communities learn about polar research and broaden participation in Science, Technology, Engineering, and Mathematics (STEM) disciplines. The Fellowship facilitates community engagement activities for polar scientists and provides time for them to work. Capitalizing on the kind of casual way that people in Alaskan rural communities have of getting to know people is what makes the SIRF model unique.

According to the recently published Sea Ice Outlook 2018 Interim Post-Season Report, the 2018 Arctic summer melt season official ended on 14 September. The September monthly averaged sea ice extent was 4.71 million square kilometers, based on the National Snow and Ice Data Center (NSIDC) Sea Ice Index. This ranks as effectively tied with 2008 for the 6th lowest in the satellite record that began in 1979.

The National Aeronautics and Space Administration's (NASA) Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) launched from Vandenberg Air Force Base in California on 15 September 2018. The ICESat-2 mission, managed by NASA's Goddard Space Flight Center, will measure the changing height of Earth's ice using the Advanced Topographic Laser Altimeter System (ATLAS), which measures height by timing how long it takes individual laser photons to travel from the spacecraft to Earth and back, with a precision of better than a billionth of a second. With this and other technological advancements of ICESat-2, scientists will be able to provide new insights into how the polar regions are changing with global temperature rise.

A recent program funded by the Office of Naval Research has focused on the sea state and boundary layer physics of the emerging Arctic, which is defined by less sea ice and larger expanses of open water in summer. After developing a climatology of the sea state in the region, the program planned and executed a 42-day field measurement campaign on the R/V Sikuliaq during the autumn of 2015. A key observation of the prevalence of pancake ice indicates that surface waves are having a significant effect on sea ice formation in the region. Along with the field campaign, the program developed and applied models for wave-ice interactions as well as models for air-ice-ocean interactions, which were tested and improved with the field data.

In 2012, the Arctic Landscape Conservation Cooperative provided support for teams of interdisciplinary scientists to address habitat and species’ responses to climate change in Arctic Alaska. The Fish CAFE team, in response to the call, developed research to address those questions in the focal watershed of Fish Creek, Alaska. The science outcomes are part of an ongoing adaptive management process that is essential to sound decision making in the NPR-A and can serve as a model for other Arctic regions facing climate and land-use uncertainty.

Since 2003, the International Arctic Research Center (IARC) has organized NSF-supported summer schools for students and early career scientists. These programs provide students with the current state of knowledge, hands-on training in conducting Arctic research, and the skills necessary to communicate science across disciplines. Experts from a range of Arctic disciplines introduce the cutting-edge science in their research areas through lectures, model-based experimentation, and field excursions. Students are guided in group projects that encourage participants to explore the intersections between traditional disciplines. An international component of the summer school provides perspectives and international collaboration— key elements of future Arctic research. Building on the knowledge gained during 15 years has led to success and innovation in the summer school program.

The University of Alaska Fairbanks (UAF) and the research vessel Sikuliaq will join partners from Europe and Canada in the newly formed Arctic Research Icebreaker Consortium (ARICE). This new international consortium, consisting of 15 partners from 13 different countries, will support planning and implementation of Arctic research cruises by better coordinating the existing icebreaker fleet, allowing researchers to compete for fully-funded ship time, and collaborating with commercial vessels to increase Arctic data collection. For the first time, scientists conducting research in the Arctic Ocean will be able to apply for fully funded access to six international icebreakers, including Sikuliaq. While cruise time will be granted to researchers based on merit, ARICE project coordinators hope the program will increase opportunities for early career researchers and scientists from countries who do not have easy access to an icebreaker.
