Methanethiol and dimethyl sulfide measurements in seawater and the atmosphere around the Antarctic Peninsula and in the Weddell Sea

Charel Wohl, Leah R. Williams, Elisabeth S. M. Deschaseaux, Lauriane L. J. Quéléver et autres

Inclusion of methanethiol (MeSH) in global atmospheric chemistry–climate model assessments has shown that MeSH emissions increase SO 2 , particulate sulfate and aerosol cooling over the Southern Ocean. However, measurements in the Southern Ocean are sparse. In February and March 2023, we …

DMS, MeSH and nanoparticles in semi-controlled deck-borne experiments using Antarctic seawater: on the effect of UV light

Guillaume Chamba, Karine Sellegri, Valérie Gros, Clémence Rose et autres

Abstract. Sulfur-containing volatile organic compounds (VOCs) such as dimethyl sulfide (DMS) and methanethiol (MeSH) are are of particular interest among oceanic VOCs emitted by the ocean, both for their central role in the marine sulfur cycle and as potential precursors to secondary …

Antarctic and Arctic science in the classroom and for society

Magda Vila, Vanessa Balagué, Clara Cardelús, Adelina Geyer et autres

Abstract The Earth’s poles have always aroused great interest and fascination, first for explorers looking for the Northern Pass in the Arctic or for a new continent and natural resources to exploit, and today for scientists due to the significant role that …

Distribution of alkylamines in surface waters around the Antarctic Peninsula and Weddell Sea

Arianna Rocchi, Mark F. Fitzsimons, Preston Akenga, Ana Sotomayor et autres

Alkylamines, volatile organic nitrogen compounds with low molecular weight, are present in the surface ocean and participate in the marine biogeochemical nitrogen cycle, atmospheric chemistry and cloud formation. Alkylamines have been detected in polar regions, suggesting that these areas constitute emission hotspots …

Assessing the relationship between viruses and protists and their role in dimethylsulphoniopropionate release in Antarctic surface microlayers

Dolors Vaqué, Elisa Berdalet, Ana Sotomayor‐García, Marta Estrada et autres

Abstract Marine microorganisms play a crucial role in biogeochemical cycles, especially in the surface microlayer (SML), which differs from adjacent subsurface waters (SSW). In this study, we sampled the SML and SSW at 20 sites along the western Antarctic Peninsula during the …

Distribution of alkylamines in surface waters around the Antarctic Peninsula and Weddell Sea

Arianna Rocchi, Mark F. Fitzsimons, Preston Akenga, Ana Sotomayor et autres

Abstract. Small molecular weight alkylamines, organic nitrogen compounds present in the surface ocean, participate in the marine biogeochemical nitrogen cycle, atmospheric processes and cloud formation. Alkylamines have been detected in polar regions, suggesting that these areas constitute emission hotspots of these compounds. …

Harmful Ostreopsis cf. ovata blooms could extend in time span with climate change in the Western Mediterranean Sea

Salomé Fabri‐Ruiz, Elisa Berdalet, Caroline Ulses, Samuel Somot et autres

Fast environmental changes and high coastal human pressures and impacts threaten the Mediterranean Sea. Over the last decade, recurrent blooms of the harmful dinoflagellate Ostreopsis cf. ovata have been recorded in many Mediterranean beaches. These microalgae produce toxins that affect marine organisms …

Basin scale variability of Ostreopsis spp. blooms provides evidence of effectiveness of an integrated sampling approach

Mariachiara Chiantore, Valentina Asnaghi, Marie Abboud‐Abi Saab, Laury Açaf et autres

Ostreopsis spp. blooms have been occurring in the last two decades in the Mediterranean Sea in association with a variety of biotic and abiotic substrata (macroalgae, seagrasses, benthic invertebrates, sand, pebbles and rocks). Cells proliferate attached to the surfaces through mucilaginous trichocysts, …

Harmful Ostreopsis cf. ovata blooms could extend in time span with climate change in the Western Mediterranean Sea.

Salomé Fabri‐Ruiz, Elisa Berdalet, Caroline Ulses, Samuel Somot et autres

The Mediterranean Sea is a region threatened by fast environmental changes and high coastal human impacts. Over the last decade, recurrent blooms of the harmful dinoflagellate Ostreopsis cf. ovata have been recorded in many Mediterranean beaches. Here we investigate whether the spatial-temporal …
