Herein we describe mating behaviour observed in a group of 20 white whales in Svalbard, Norway. A single female was the centre of attention during the 45-minute encounter, which was observed, photographed and videotaped at an ice edge in Storfjorden in June 2022. Several males surrounded the female and vigorously herded her from all sides. The female spy-hopped regularly, and sometimes her whole body was pushed out of the water by the other animals. High tail-lifts and tail-slapping were frequently performed by males, and erect penises were observed many times. Trumpet calls were also heard. At one point, three males …

The Spitsbergen population of bowhead whales (Balaena mysticetus) was harvested to near extinction during the whaling era. Here, we show possible signs of recovery of the population by reporting observations of two calves in the Scoresby Sund polynya in East Greenland on 2 and 4 May 2022, and it is the first observation of this kind in this area since the early 1900s.

Many areas in the Arctic are vulnerable to the impacts of climate change. We observe large-scale effects on physical, biological, economic and social parameters, including ice cover, species distributions, economic activity and regional governance frameworks. Arctic living marine resources are affected in various ways. A holistic understanding of these effects requires a multidisciplinary enterprise. We synthesize relevant research, from oceanography and ecology, via economics, to political science and international law. We find that multidisciplinary research can enhance our understanding and promote new questions and issues relating to impacts and outcomes of climate change in the Arctic. Such issues include recent …

Cooperation in the Arctic region has been fruitful in the past few decades, generating several multilateral organizations and forums covering the entire circumpolar North. In many cases, forums were created to serve as catalysts, bringing together decision-makers from different backgrounds in a conference setting to promote dialogue and the exchange of ideas. To enquire about the possibility of creating a forum of cooperation in the eastern North American Arctic, a total of five governmental officials from Canada, Denmark, Nunavut, Québec and Greenland, and one elected representative from Greenland were interviewed with the same set of five questions. The governmental officials …

The Queen of the Arctic: Louise Arner Boyd

Louise Boyd (1887–1972) was a female pioneer in Arctic research whose legacy includes the exploration of north-east Greenland. In this Perspective piece, we use a broad interdisciplinary approach to investigate her career as a photographer and expedition leader. When documenting glacial retreat during the 1930s, she was at the forefront of the development of glaciology as a research discipline. Without family obligations and with seemingly inexhaustible financial resources, she used Arctic exploration to create an independent and self-defined life for herself.
