Direct observation is challenging as satellite sensors have a coarse spatial resolution and cannot detect the fine fractal structure of the ice. Deploying human-crewed ships to the area is also difficult due to extreme weather conditions and obstacles posed by floating broken ice. Moreover, traditional ocean observation methods offer limited temporal and spatial coverage, while drones and autonomous underwater vehicles (AUVs) are hindered by energy constraints that restrict their research potential.

To date, researchers have identified the new algae species in the Arctic tundra on Svalbard and in coastal dunes along the Baltic Sea, indicating a broader regional distribution than previously assumed.

The polar bear (Ursus maritimus) is the only Arctic land mammal that dives into water to hunt. Despite thermal insulation provided by blubber and fur layers and low Arctic temperatures, their fur is typically observed to be free of ice. This study investigates the anti-icing properties of polar bear fur. Here, we show that polar bear fur exhibits low ice adhesion strengths comparable to fluorocarbon-coated fibers, with the low ice adhesion a consequence of the fur sebum (hair grease).

The Society of American Military Engineers (SAME) Anchorage Post announces the Arctic Industry Forum for 2025. This event brings together senior leaders and practitioners focused on addressing matters affecting National Security that have effects in the built and natural infrastructure environments.

Emergency management in the Arctic is a fast-changing landscape. There have been many developments to emergency prevention, preparedness and response, while at the same time, risk factors and environmental and social conditions are rapidly changing. This event is hosted by the Arctic Council.

In lead up to its 35th anniversary in 2025, the International Arctic Science Committee (IASC) is coordinating a multi-year planning process for the Fourth International Conference on Arctic Research Planning (ICARP IV) that will engage Arctic researchers, policymakers, residents, and stakeholders from around the world to collegially discuss the state of Arctic science, the place the Arctic occupies in global affairs and systems, to consider the most urgent knowledge gaps and research priorities that lie before us and to explore avenues to address these research needs. This event is hosted by a consortium of US institutions, including the University of Colorado Boulder, University of Northern Iowa, University of Alaska Fairbanks, and Alaska Pacific University. ICARP I, II, and III focused the attention of the world’s researchers toward the value of strategic international coordination in accelerating progress in addressing critical challenges. ICARP IV will build upon this concept by striving to achieve consensus and build collaborations among the leading scientific, academic, environmental, Indigenous and political organizations currently concerned with Arctic issues.

Arctic Encounter, North America’s leading conference on Arctic policy and business, annually gathers over 1,000 participants from more than two dozen countries. As a nonprofit NGO, Arctic Encounter convenes and hosts dialogues and policy debates among international leaders, business executives, Indigenous representatives, federal agencies, diplomats, scientists, and policymakers. Hosted in downtown Anchorage, Alaska, the event offers participants a unique blend of arts, culture, and critical discussions, contributing to a deeper understanding of Arctic challenges and opportunities.
