With China becoming more active in Greenland, worries abound that China might have hidden intentions. Despite that, the Greenlandic government is showing an increasing interest in deepening its cooperation with China. This article explores Greenland’s motivation behind its positive attitude towards China and examines whether China will be a threat to Greenland’s independence. For Greenland, China is both a deep-pocketed investor and a huge consumer market, especially in the mining, fishing and tourism industries. Greenland, therefore, views China as an important partner in its economic development, which is necessary for its independence from Denmark. Considering China’s relationship with Denmark, its …

This study uses cetacean sighting data, acquired via a citizen science programme, to update distributions and spatial trends of whales and dolphins in waters around the Svalbard Archipelago during the period 2005–2019. Distributions, based on kernel density estimates, from an early period (2005–2009) and a recent period (2015–19) were compared to identify potential shifts in distribution in this area, which is experiencing rapid warming and concomitant sea-ice losses. Among the three Arctic endemic cetaceans, white whales (Delphinapterus leucas, also known as beluga) had a stable, coastal distribution throughout the study, whereas narwhals (Monodon monoceros) and bowhead whales (Balaena mysticetus) were …

Alfred Edwin Eaton (1844–1929) was amongst numerous Victorian naturalists whose exotic collections disseminated to the natural history museums of Britain laid the groundwork for our understanding of biodiversity. What sets him apart from his contemporaries was his first-hand knowledge of organisms at the polar extremes. This paper describes Eaton’s contributions to polar biology, especially in the field of entomology, from two high-latitude expeditions: the 1873 Benjamin Leigh Smith Expedition to Svalbard in the European Arctic and the 1874 British Transit of Venus Expedition to Kerguelen Island in the southern Indian Ocean. His observations of flightless polar and subpolar insects, in …

Co-authorship networks can provide key insights into the production of scientific knowledge. This is particularly interesting in Antarctica, where most human activity relates to scientific research. Bibliometric studies of Antarctic science have provided a useful understanding of international and interdisciplinary collaboration, yet most research has focused on broad-scale analyses over recent time periods. Here, we take advantage of a ‘Goldilocks’ opportunity in the McMurdo Dry Valleys, an internationally important region of Antarctica and the largest ice-free region on the continent. The McMurdo Dry Valleys have attracted continuous and diverse scientific activity since 1958. It is a geographically confined region with …

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 …

Moss tundra with a thick peat layer dominated by bryophytes is one of the most important ecosystems in the High Arctic of Svalbard, but little is known about the carbon dynamics of moss tundra. Here, we estimated the net primary production (NPP) and net ecosystem production (NEP) of moss tundra on Brøggerhalvøya (Brøgger Peninsula) of north-western Svalbard (79°N). The net photosynthetic and respiration rates of the two dominant moss species, Calliergon richardsonii and Tomenthypnum nitens, were measured under laboratory conditions. On the basis of the photosynthetic and respiration characteristics and climatic data, we estimated the cumulative NPP of the dominant …

Bowhead whales (Baleana mysticetus) are usually away from west Greenland waters during summer. Reported here is an observation of at least six bowhead whales in July 2022 in the Uummannaq Fjord system of west Greenland.

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 …

We describe the main features of LT variability that influence native vascular plants in the Antarctic and examine the relationship between the temperature regime at the micro-level and meteorological conditions at the macro-level. We used a period of over a year, during which 37 specialized mini-loggers recorded LT near vascular plants in the Argentine Islands–Kyiv Peninsula region of the Antarctic Peninsula. Rather than measuring standard air or soil temperature, these loggers detect the temperature near the ground, in the microhabitats that harbour vascular plants. On a daily scale, LT correlates with standard (2-m) air temperature, with the values higher at …

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 …
