The Sea Ice Outlook (SIO), an activity of the Sea Ice Prediction Network (SIPN), provides an open forum for researchers and others to develop, share, and discuss seasonal Arctic sea ice predictions. The SIO produces reports in June, July, and August containing a variety of perspectives on Arctic sea ice—from observations of current conditions, to advanced numerical models, to qualitative perspectives from citizen scientists. A post-season report provides an in-depth analysis of factors driving sea ice extent in the summer and explores the scientific methods for predicting Arctic sea ice. Key highlights from the SIO 2017 Post-Season Report, released earlier this month, include discussion of 2017 Arctic weather and ice conditions; the Outlook contributions and methodologies, including regional forecasts; and sea ice extent probability maps. The report also includes discussion of contributions for forecasts of the Antarctic maxima through the "SIPN South" project.

Indigenous values, cosmologies, and frameworks are critical to the future of conservation, natural resource management, and climate change sciences. These are pillars from which to craft researcher-community relationships that have specific policy outcomes that support pursuits of sovereignty and self-determination.The Leadership and Strength project, which began in 2009, is a decade-long process of collaboration with local advisors and community members in Utqiaġvik, Alaska (formerly known as Barrow). This project draws upon engaged community-based research approaches to examine community strength and well-being and to focus on the pathways that women, men, and families forge to live well in Utqiaġvik. The stories shared as part of this work discussed historical legacies in the community that were sources of trauma as well as positive stories of community leadership and strength.

The eight member states of the Arctic Council vowed to improve cooperation on Arctic science via a legally binding agreement, entitled "Agreement on Enhancing International Arctic Scientific Cooperation” signed on 11 May 2017 at the Arctic Council Ministerial meeting in Fairbanks, Alaska. The goal of this science agreement is to facilitate access, whether to territory and research areas, platforms, infrastructure, facilities, materials, samples, data, or equipment. In the words of Secretary of State Rex Tillerson, the document promises to ease "the movement of scientists, scientific equipment and, importantly, data sharing" across the North. Barriers to research, such as denied visas, the inability to carry equipment and samples across national borders, or denial of access to data, preclude scientific investigation, slow progress, increase cost, and retard the growth of knowledge.

In a recent study, a team of investigators analyzed oxygen-18 isotopes (δ¹⁸O) from the otoliths—or ear bones—from archeological Pacific cod (dating about 1790-1920) to reconstruct nearshore temperature regimes in the Gulf of Alaska. By comparing those values to δ¹⁸O levels in fish sampled in the same location in 2004, the team determined that ocean temperatures in the Gulf of Alaska today are about 3˚C warmer than they were during the late Little Ice Age (LIA) two centuries ago. The work was supported by NSF, the National Park Service, and the Oceans Alaska Science and Learning Center in Seward, Alaska.

In mid-March 2017, nine midshipmen and four faculty members from the U. S. Naval Academy (USNA) participated in a joint ice experiment (ICEX) with the NASA Operation IceBridge, an airborne survey program established to mitigate the gap in polar observations between the termination of NASA's Ice, Cloud and Land Elevation Satellite (ICESat) and ICESat-2, scheduled to launch in 2018. The team from USNA were members of the Polar Science and Technology Program, which is an initiative that engages students in technology innovation and introduces them to Arctic environments. The overall goal of the exercise was to collect measurements of snow and ice along the Thule Air Base survey track for validation of NASA Operation IceBridge airborne radar systems. The Thule Air Base track is part of the NASA Operation IceBridge mission inventory. It is revisited each year to monitor snow and ice changes in the polar regions.

The U.S. Department of State's Bureau of Educational and Cultural Affairs has announced the launch of the second Fulbright Arctic Initiative, which will run from spring 2018 through fall 2019. This program follows the first Fulbright Arctic Initiative (2015–2017), which was a new multidisciplinary and multinational team research program designed around specific applied research challenges in the areas of water, energy, and health and infrastructure. The first Fulbright Arctic Initiative, which coincided with the U.S. chairmanship of the Arctic Council, was designed to create a network to stimulate international research collaboration on Arctic issues and build the relations between the people of the United States and the people of other countries that are needed to solve global challenges.

In the past 10 years, PolarTREC has provided over 150 U.S. teachers with hands-on experiences with researchers working in the Arctic and Antarctica. In turn, those 150 teachers have reached thousands of students both in and out of their classroom. Data collected through the program evaluation demonstrates that these research experiences impact the teachers long after the initial experience. Every year, PolarTREC teachers are recognized for their dedication to science education. Many have received awards, are featured in the news and present at local and national meetings. These teachers share their experiences as they happen, and carry a new perspective back to the classroom.

Historical documents can provide valuable context for current changes in sea ice and climate conditions. A recent review of the history of sea-ice observations included examination of the journals and charts from Captain James Cook's third voyage as he sailed north through Bering Strait into the Arctic Ocean in search of the Northwest Passage. Cook's documents from 1778 and 1779 provide the earliest historical record of the summer sea-ice edge in the Chukchi Sea.

The University of Alaska and the Alaskan Host Committee to the Arctic Council will host the 2017 Week of the Arctic in Fairbanks and Anchorage, Alaska during the week of 8-14 May 2017. The schedule includes a series of events to advance the scientific and technical understanding of Arctic policy, human-environmental interactions, and stakeholder information needs.

The most recent nationwide project to assess Arctic knowledge, the Polar, Environment, and Science (POLES) survey, was carried out in two stages in August and November–December of 2016. One unique feature of this survey was its deliberate oversampling of Alaska residents, which allowed a first-time comparison of their Arctic knowledge with that of other U.S. residents.
