A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID)
Read more of: A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID)The paleoclimate community has an interest in distributed subglacial bedrock sampling but, while capable drill systems do exist, they are often incompatible with Twin Otter logistics. To address this issue, […]

Late Miocene wood recovered in Bengal–Nicobar submarine fan sediments by IODP Expedition 362
Read more of: Late Miocene wood recovered in Bengal–Nicobar submarine fan sediments by IODP Expedition 362Drilling and coring during IODP Expedition 362 in the eastern Indian Ocean encountered probably the largest wood fragment ever recovered in scientific ocean drilling. The wood is Late Miocene in […]

Assessing distribution shifts and ecophysiological characteristics of the only Antarctic winged midge under climate change scenarios
Read more of: Assessing distribution shifts and ecophysiological characteristics of the only Antarctic winged midge under climate change scenariosParts of Antarctica were amongst the most rapidly changing regions of the planet during the second half of the Twentieth Century. Even so, today, most of Antarctica remains in the […]

Underway seawater and atmospheric measurements of volatile organic compounds in the Southern Ocean
Read more of: Underway seawater and atmospheric measurements of volatile organic compounds in the Southern OceanDimethyl sulfide and volatile organic compounds (VOCs) are important for atmospheric chemistry. The emissions of biogenically derived organic gases, including dimethyl sulfide and especially isoprene, are not well constrained in […]

Cryptic speciation in gentoo penguins is driven by geographic isolation and regional marine conditions: Unforeseen vulnerabilities to global change
Read more of: Cryptic speciation in gentoo penguins is driven by geographic isolation and regional marine conditions: Unforeseen vulnerabilities to global changeThe conservation of biodiversity is hampered by data deficiencies, with many new species and subspecies awaiting description or reclassification. Population genomics and ecological niche modelling offer complementary new tools for […]

Can DEB models infer metabolic differences between intertidal and subtidal morphotypes of the Antarctic limpet Nacella concinna (Strebel, 1908)?
Read more of: Can DEB models infer metabolic differences between intertidal and subtidal morphotypes of the Antarctic limpet Nacella concinna (Strebel, 1908)?Studying the influence of changing environmental conditions on Antarctic marine benthic invertebrates is strongly constrained by limited access to the region, which poses difficulties to performing long-term experimental studies. Ecological […]

Variation in live-capture rates of albatrosses and petrels in fisheries, post-release survival and implications for management
Read more of: Variation in live-capture rates of albatrosses and petrels in fisheries, post-release survival and implications for managementBycatch of seabirds in longline fisheries includes mortalities and live captures (mainly during hauling). Excluding outliers, the latter accounts for 5–70% (mean 40.4%) of all bycaught birds in demersal, and […]

Effects of zinc (Zn) and chromium (Cr) on the phenol-degrading bacteria growth kinetics
Read more of: Effects of zinc (Zn) and chromium (Cr) on the phenol-degrading bacteria growth kineticsHeavy metals occur naturally within the earth crust; however, anthropogenic activities can artificially introduce these elements into the environment. Despite being the foremost isolated continent, Antarctica is not free from […]

High mercury levels in Antarctic toothfish Dissostichus mawsoni from the Southwest Pacific sector of the Southern Ocean
Read more of: High mercury levels in Antarctic toothfish Dissostichus mawsoni from the Southwest Pacific sector of the Southern OceanMercury is a bioaccumulating toxic pollutant which can reach humans through the consumption of contaminated food (e.g. marine fish). Although the Southern Ocean is often portrayed as a pristine ecosystem, […]

Remote sensing reveals Antarctic green snow algae as important terrestrial carbon sink
Read more of: Remote sensing reveals Antarctic green snow algae as important terrestrial carbon sinkWe present the first estimate of green snow algae community biomass and distribution along the Antarctic Peninsula. Sentinel 2 imagery supported by two field campaigns revealed 1679 snow algae blooms, […]
