An unexpected guest


In the autumn of 2013 an unexpected guest appeared on Svalbard - it came into Isfjorden in august, and pleased many locals with it presence during a very short autumn visit. Already from the middle of September it seemed to have left. But by that time, its presence had already been noted by Svalbardposten and was about to be discussed both in Nordlys and Bladet Fiskaren. The discovery in Isfjorden represent the by far most northern observation ever - more than 5 degrees latitude north of its previous northernmost documented observation. Despite intensive search, it appears not to have been back since. Who are we talking about - the Atlantic mackerel!

The findings resulted in some buzz in the newspapers (Svalbardposten, Fiskeribladet Fiskaren, Nordlys, Nordlys again, Aftenposten) and just recently in a scientific publication in the journal "Arctic".

Polar Night exhibition
Life and light in the polar night is the title of an exhitibition inspired by the projects Marine Night, CircA and others. The exhibition in the Polar Museum in Tromsø opened on Jan 18th. You can find an online exhibition catalogue in English here and in Norwegian here. The flyer from the exhibition opening can be found here.

New member of the Mare Incognitum family

ArcticABC autonomous observatory
ArcticABC autonomous observatory
From early 2015, a new project will be initiated within the mare Incognitum family. Not only is it a new project, it is the largest project so far of all Mre Incognitum projects with a total budget of 50 million NOK.  

This innovative and challenging research project is spearheaded by the development of new autonomous underwater technology, with the primary goal of determining the ecosystem consequences of the ongoing reduction in the Arctic sea ice. The project is based on three tightly-linked core modules: The applied technology module focuses on data acquisition and autonomous observations in areas and habitats yet to be systematically and scientifically explored. Specifically, we will develop an under-ice-tethered observatory (see picture) with real-time data transmission to be deployed for a full year in the Central Arctic Ocean. The biological interactions module focuses on coupling processes between the sea-ice and the ocean, aimed at answering the fundamental question of whether species composition and production regimes in Arctic marine ecosystems will be permanently altered following a continued reduction of the Arctic ice cover. The consequences module will explore and forecast possible consequences of reduced ice cover at increasing levels of complexity, ranging from individuals to populations up to the entire ecosystem and society at large and geopolitics. The project focuses on method development, technology adaption to an extreme operating environment, consequences for the deep central Arctic Ocean ecosystem of climate change, and on building a cross-disciplinary nationally and internationally coordinated consortium bridging technology and life sciences.

Marine Night seminar for Kings Bay with first results

 The Marine Night project was invited to give one of three presentations at this year's Kings Bay juleseminar (Christmas seminary). On behalf of the project, Eva Leu presented first results of our 2014 winter campaign in Kongsfjorden in January 2014. As this has been the by far largest research activity ever carried out in Ny-Ålesund in the middle of wintertime, it was a very special experience – not only for us, but also for the people working there. We had gotten fantastic support this year, and I was informed that the window front in the Marine Lab has already been covered again with two layers of rubbish bags for our coming January campaign. The audience was very interested to hear results about the high levels of biological activities we had observed, and were impressed by the strong national and international collaboration network, interdisciplinarity, and involvement of students in our project. You can find the presentation, with some of the preliminary Marine Night 2014 results here (PDF).

Mare Incognitum at the Arctic Change conference in Ottawa (Canada)

Arctos researchers were very well represented at the recent Arctic Change conference in Ottawa (Canada). In total, the conference gathers more than 1300 people, with Norway being the third largest delegation behind Germany and USA. Arctos were represented by one plenary keynote speaker in the opening session (Professor P Wassmann), and two scientific sessions. The conference was hosted by ArcticNet, a network of excellence with whom Arctos has very close ties. One of the scientific sessions were focused on the polar night and the research carried out within four Mare Incognitum projects; Circa, Marine Night, Cleopatra 2 and SpitsEco. A total of six talks were given in this session (PDFs of the talks below):

Big Black Box Workshop in Tromsø 19 and 20 January

BBB logoMarine ecological processes during the polar nightwhat do we know and how to proceed?

UiT The Arctic University of Norway, Campus Tromsø, 19th – 20th January 2015

The extended period of Arctic darkness, known as the polar night, may limit organism survival and reproductive success because of the associated food limitation.  Even if the polar night only exist for +/-4 months, depending on latitude, Arctic marine environments may experience complete darkness for up to ten months because of extensive sea ice and snow conditions. A long overwintering period and a brief growing season are likely the main barriers for “temperate/lower latitude” species to keep sustainable populations in the Arctic. The temperate species lack the life history adaptations of high-Arctic species that allow them to cope with such extreme seasonality. However, our knowledge on winter ecology is extremely poor in comparison to ecological processes during the productive summer season. Gathering additional information on polar night ecology and processes is crucial, especially in light of expected impacts of climate change on Arctic marine ecosystems.  We therefore invite you to this Big Black Box workshop to convene an international group of experts to

1) develop one white paper summarizing existing knowledge on winter ecology in the Arctic

2) identify the most critical knowledge-gaps

3) discuss a new international initiative/program focusing on polar night ecology

Group picture AWI meeting

End of November German, Russian and Norwegian scientists and students involved in the projects CLEOPATRA II and COPPY met at Alfred Wegener Institute to discuss project results and publications. Project leader Janne E. Søreide (UNIS) gave also a lecture on stable isotope and fatty acid trophic markers at the weekly AWI colloquium with title:  

Sympagic-pelagic-benthic coupling in Arctic marine ecosystems revealed by stable isotopic and fatty acid tracers

(for the talk see this PDF).

Report from the dark side

Aftenposten Viten

The deep ocean and the darkness carry secrets, and they may bring fear for many. What, and who, hides in the dark, cold and deep ocean? The Arctic polar night has for a long time been almost inaccessible - and it is still not an easy place to carry out research. Not only has it remained inaccessible, the scientific literature has generally dismissed the ocean during the polar night as a marine desert. No light - no life. We have generally assumed that the organisms shut down and remain inactive in wait of the spring. Until now. In January, a new exhibition in the Polar museum (Polarmuseet) in Tromsø will have this topic as the main theme. In the meantime you can find out more in a recently published outreach article in Aftenposten (Norwegian only).

Life in a cold climate

Science and Technology CoverIs there a stronger resilience to climate change in Arctic marine organisms than anticipated? These organisms have evoloved unique adaptations to survive strong seasonal changes which may make them less vulnerable. The CLEOPATRA II project focuses on the Arctic zooplankton physiology and life history to predict the degree of match/mismatch of key biological proecesses in a changing Arctic. Read more in the recent outreach article in Science and Technology.
