• Wintertime organic carbon export provides a potential food source for zooplankton in the High Arctic (2026) · Communications Earth & Environment · doi

  The magnitude and implications of wintertime particulate organic carbon export in ice-covered Arctic waters are not well understood. The role of wintertime carbon export as a food source for overwintering zooplankton is unclear. The drivers of wintertime carbon export in the High Arctic are not well studied.

• Wintertime organic carbon export provides a potential food source for zooplankton in the High Arctic (2026) · Communications Earth & Environment · doi

  Limited light availability and reduced microalgal production during winter make it challenging to study wintertime particulate organic carbon export. The remote and ice-covered location of the study area poses logistical challenges for data collection. The complexity of Arctic marine ecosystems makes it difficult to understand the ecological role of wintertime carbon export.

• TundraFlux: a database of ecosystem respiration with biotic and abiotic metadata from Arctic and alpine tundra warming experiments (2026) · Earth System Science Data · doi

  Empirical in-situ measurements of ecosystem carbon dioxide respiration in high-latitude ecosystems are limited. There is a need for a comprehensive dataset of ecosystem respiration measurements from Arctic and alpine tundra warming experiments.

• Organic carbon pathways across the fluvial-marine transition zone of the Mackenzie River Delta – Beaufort Sea region and implications on ocean color remote sensing (2026) · Biogeosciences · doi

  Arctic warming and hydrological intensification are accelerating permafrost thaw and increasing the export of terrestrial organic carbon (OC) and sediments from land via rivers and shallow coastal waters into marine waters, yet the fate of these materials in deltaic and coastal transition zones remains poorly understood.

• Krill defecation at depth reduces carbon flux attenuation in the Weddell Sea euphotic zone (2026) · Ocean science · doi

  There is a need for contemporary observations of carbon sequestration processes in the Weddell Sea. The impact of climate-driven changes in sea ice on carbon sequestration processes is not well understood. The role of zooplankton-mediated processes in determining particle flux is not well quantified.
