Marine Fungi & Mineral Ballasting - An Influence on Arctic Carbon Export?

The Arctic Research Icebreaker Consortium (ARICE, www.arice-h2020.eu/) and Association of Polar Early Career Scientists (APECS, www.apecs.is) invited for a webinar on Marine Fungi & Mineral Ballasting -  An Influence on Arctic Carbon Export? on 27 October 2021 from 09:00 – 10:00 am GMT

Sea ice is a unique habitat for microbes and has been shown to host highly productive sea-ice algal communities. During growth, algae can exude polysaccharides that can aggregate and form TEP (Transparent Exopolymer Particles), sugar-rich particles that are attractive food sources for marine bacteria and fungi. But some marine fungi can also live as parasites, directly benefiting from attaching to the sea-ice algae. This in turn can influence how well the sea-ice algae grow and how many polysaccharides they can produce.

At certain temperatures, gypsum crystals can form in the sea ice and due to their weight sink rapidly in the water column when the ice starts melting. As TEP are inherently very sticky, they potentially also stick to gypsum and get ballasted, causing them to sink rapidly out of the water column and export the carbon from the polysaccharides.

The ARICE funded ProMis (Production and export of phytoplankton-derived organic matter in the changing Arctic Ocean – Role of parasites, saprotrophs and mineral) project onboard IB Oden aimed at characterizing the influence of fungi on TEP production and degradation and looking at the influence of gypsum on TEP-related carbon export. In this webinar we will give an overview of the scientific background and aims of the project as well as samples collected.

Speakers are Birthe Zäncker (Marine Biological Association of the UK), Michael Cunliffe (Marine Biological Association of the UK) and Jutta Wollenburg (Alfred-Wegener Institute)

Moderation: Franziska Pausch (ARICE, AWI & APECS)

Arctic Ocean Ventilation – Why it matters and how to measure it

The Arctic Research Icebreaker Consortium (ARICE, arice-h2020.eu) and Association of Polar Early Career Scientists (APECS, apecs.is) invited for a webinar on “Arctic Ocean Ventilation – Why it matters and how to measure it” on 11 October 2021 from 12:00 – 13:00 pm GMT

The Arctic Ocean is a critical part of the global ocean and the global climate system, and we know climate change is happening faster there than anywhere else on the planet. With this in mind, the VACAO (Ventilation and Anthropogenic Carbon in the Arctic Ocean) project, funded by ARICE, set out to better quantify Arctic Ocean ventilation. With ventilation we mean the process that brings water from the surface ocean to the deep ocean, and back again. This process bring characteristics of the atmosphere to the interior ocean, such as extra heat and carbon dioxide, and eventually distribute this to the global ocean. We report on preliminary results from a very recent cruise on the IB Oden where we measured and took samples for a large range of ocean ventilation tracers.

Speakers are Toste Tanhua (GEOMAR), Lennart Gerke (GEOMAR) and Yannis Arck (University Heidelberg).

Moderation: Franziska Pausch (ARICE, AWI & APECS)

DEARice in MOSAiC – Connecting the world of snow, ice and ecosystem processes

The Arctic Research Icebreaker Consortium (ARICE, www.arice.eu) and Association of Polar Early Career Scientists (APECS, www.apecs.is) invited for a webinar on DEARice in MOSAiC – Connecting the world of snow, ice and ecosystem processes on 4 June 2021 from 8:00 – 9:30 am GMT.

The ARICE funded project DEARice (DEvelopment of snow/ice/ecosystem models using winter-to-summer ARctic observations of coupled snow, ice, and ecosystem processes) took part during the MOSAiC expedition. The aim was to collect unique data on snow and sea ice over a full year to improve our process-level understanding of processes that can eventually feed into the improvement of models. The COVID-19 pandemic caused substantial changes in the leg planning after April 2020, however, the resulting data set is very close to the optimal outcome. Serendipitous luck made it possible to sample snow for all four seasons, including the mysterious summer “snow”, called surface scattering layer. The results from this project encompass all relevant spatial scales, from microstructural processes in the snowpack and at the ice surface, to ridge scale observations of snow distribution and ice thickness, to snow-atmosphere interactions and albedo processes of the sea ice cover. Understanding how these different scales interact will improve our understanding of the vulnerability of the Arctic sea ice system, and decrease uncertainties in climate projections.

Speakers are Martin Schneebeli (WSL Institute for Snow and Avalanche Research SLF), Ruzica Dadic (Victoria University of Wellington), Polona Itkin (UiT - The Arctic University of Norway), Jari Haapala (Finnish Meteorological Institute) and Henna-Reetta Hannula (Finnish Meteorological Institute)

Webinar: ARICE, the ice and the fish. An Arctic expedition from planning to first results

The Arctic Research Icebreaker Consortium (ARICE, arice.eu/) and Association of Polar Early Career Scientists (APECS, apecs.is/) invited for a science webinar on 28 May 2020, 4-5 pm GMT.

In November 2019, the US icebreaker RV Sikuliaq headed to the north side of Alaska for a combined oceanographic and biological expedition. The biological work was performed within the ARICE-funded project GO-WEST. GO-WEST aimed to investigate the association of young polar cod (or Arctic cod, Boreogadus saida) with the newly forming sea ice, its prey field and carbon sources. Polar cod is a keystone species of the Arctic food web. The young (0-2 year-old) fish use the under-ice habitat as a foraging ground and shelter from predators. It has been hypothesized that juveniles get entrained with the new sea ice in autumn and use it as a transportation vector over large distances. The changing icescape of the Arctic Ocean will affect this close relationship between fish and sea ice. The ARICE expedition GO-WEST aimed to sample for the first time young polar cod at the underside of new sea ice between autumn and winter, and to investigate their survival conditions. To this end, we used a Surface and Under-Ice Trawl capable to skim the underside of sea ice. The first results of this expedition show that young polar cod were present in the under-ice habitat throughout the investigation area, along with their main prey species. During this webinar we will briefly explain how the expedition was planned and which logistical obstacles needed to be overcome. We will focus on how the field work was conducted in collaboration with the chief scientist and the crew of RV Sikuliaq, and how first raw data were generated. Finally we will give an outlook on sample elaboration, data processing and publications.

Speakers are Hauke Flores (AWI Bremerhaven) and Mai Apasiri Klasmeier (Ruhr University Bochum). Moderation: Josefine Lenz (AWI & APECS)
