The endangered population of humpback whales () breeding and calving off the Cape Verde Islands (CVI) are known to migrate to feeding areas located along the eastern margin of the North Atlantic Ocean (Iceland, and Norway). Here, we report for the first time a confirmed migration of an individual humpback whale from CVI breeding ground to a western North Atlantic feeding ground of West Greenland. This individual humpback, which was photographed and identified off the coast of West Greenland in 2021, was previously documented in CVI 22 years before (1999). An annual subsistence hunt for humpbacks occurs in West Greenland and the resighting at this location with a humpback whale from CVI has strong implications for the conservation efforts of the small CVI population.

Article Synopsis
  • The discharge of calved ice and subglacial runoff in Disko Bay, home to Sermeq Kujalleq glacier, is expected to influence marine biogeochemistry, particularly affecting the marine silica cycle due to elevated dissolved silica (dSi) from glaciers.
  • The study analyzes silica dynamics in various regions around Disko Bay, finding that land-terminating glaciers show conservative dSi patterns, whereas marine-terminating glaciers significantly alter nutrient distribution through subglacial discharge plumes.
  • The research quantifies contributions to dSi enrichment, highlighting that a large fraction comes from saline water entrainment, with minor contributions from icebergs and amorphous silica dissolution, ultimately adding a small but significant dSi flux to the environment.

The oceans play a pivotal role in mitigating climate change by sequestering approximately 25% of annually emitted carbon dioxide (CO). High-latitude oceans, especially the Arctic continental shelves, emerge as crucial CO sinks due to their cold, low saline, and highly productive ecosystems. However, these heterogeneous regions remain inadequately understood, hindering accurate assessments of their carbon dynamics.

The work presented here marks a further advance in expert uncertainty quantification. In a recent probabilistic evaluation of ice sheet process contributions to sea level rise, tail dependence was elicited and propagated through an uncertainty analysis for the first time. The elicited correlations and tail dependencies concerned pairings of three processes: Accumulation, Discharge and Run-off, which operate on major ice sheets in the West and East Antarctic and in Greenland.

Flowering time synchronizes reproductive development with favorable environmental conditions to optimize yield. Improved understanding of the genetic control of flowering will help optimize varietal adaptation to future agricultural systems under climate change. Here, we investigate the genetic basis of flowering time in winter wheat (Triticum aestivum L.

Persistent organic pollutants among seafood processing workers in West Greenland.

Centre for Arctic Health & Molecular Epidemiology, Department of Public Health, Aarhus University, Bartholins Allé 2, 8000, Aarhus, Denmark; Greenland Centre for Health Research, University of Greenland, Manutooq 1, 3905, Nuussuaq, Greenland.

The Greenlandic population is highly exposed to persistent organic pollutants (POPs) through the consumption of traditional marine food, including marine mammals. Central to Greenland's economy and cultural identity, the fishing industry employes about 15% of the working population. This study investigated POP exposure, including polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), and per- and polyfluoroalkyl substances (PFASs), among seafood processing workers at the Greenlandic west coast.
