Global Fjords as Minor Sources of Nitrous Oxide to the Atmosphere
Geophysical Research LettersWe report high‐resolution observations of N2O sea‐air fluxes at six fjords spanning arctic, subarctic, and temperate climates. Icelandic and Swedish fjords were sources of N2O at 97.6 ± 10.5 and 19.9 ± 19.3 μg N2O m−2 day−1, respectively.

Capacity of Arctic fjord sediments to degrade carbohydrates from permafrost active layer [PDF]
Microbiology SpectrumThe degradation of organic matter (OM) by microorganisms in thawing permafrost produces greenhouse gases. Terrestrial OM is transported into fjords through hydrological runoff, but it is unclear whether the microbial mechanisms of OM degradation on land ...

Patagonian Fjords/Channels vs. Open Ocean: Phytoplankton Molecular Diversity on Southern Chilean Coast [PDF]
MicroorganismsEnvironmental filtering studies have revealed immense oceanic microbial diversity, yet the Southeast Pacific remains comparatively undersampled. We characterize the molecular diversity of phytoplankton across two biogeographic domains with contrasting ...

Long-term nitrogen burial exceeds denitrification in global fjords [PDF]
Nature CommunicationsNitrogen (N) availability regulates primary productivity and hence directly affects global oceanic carbon sequestration. Global fjords account for up to 11% of marine carbon burial. However, N loss via sediment burial remains largely unquantified.

Arctic Science, 2021 Climate change is rapidly modifying marine fish assemblages in the Arctic. As fish eggs and larvae have a narrower thermal tolerance than nonreproductive adults, their response to increasing temperatures is likely one of the main drivers of these changes.

Megafaunal communities in rapidly warming fjords along the West Antarctic Peninsula: hotspots of abundance and beta diversity. [PDF]
PLoS ONE, 2013 Glacio-marine fjords occur widely at high latitudes and have been extensively studied in the Arctic, where heavy meltwater inputs and sedimentation yield low benthic faunal abundance and biodiversity in inner-middle fjords.

Hermit crabs (Pagurus spp.) at their northernmost range: distribution, abundance and shell use in the European Arctic [PDF]
Polar Research, 2015 Hermit crabs are important components of Arctic benthic systems, yet baseline data on their densities and distribution patterns in this rapidly changing region are still scarce.

Subglacial‐Discharge Plumes Drive Widespread Subsurface Warming in Northwest Greenland's Fjords
Geophysical Research Letters, 2023 Greenland's glacial fjords modulate the exchange between the ice sheet and ocean. Subglacial‐discharge‐driven plumes adjacent to glaciers may exert an important influence on fjord water properties, submarine glacier melting and the export of glacially ...

Influence of Estuarine Water on the Microbial Community Structure of Patagonian Fjords
Frontiers in Marine Science, 2021 Fjords are sensitive areas affected by climate change and can act as a natural laboratory to study microbial ecological processes. The Chilean Patagonian fjords (41–56°S), belonging to the Subantarctic ecosystem (46–60°S), make up one of the world’s ...

Radionuclide activities in sediments on the northern coast of Spitsbergen
Polish Polar Research, 2017 The specific activity of natural gamma emitters like actinium (228Ac), bismuth (212Bi, 214Bi), lead (212Pb, 214Pb), potassium (40K), radium (224Ra), thallium (208Tl) and artificial radioisotope caesium (137Cs) was measured in 2005 in the surface layer of
