CLEOPATRA II: Climate effects on planktonic food quality and trophic transfer in Arctic Marginal Ice Zones II ended officially 1 of July 2015.
This highly international 3-year project has so far resulted in one completed PhD thesis and 3 completed master theses. At present eight papers are published, two articles are in review, and 8 manuscripts are in progress. In addition, project results have been presented at several national and international meetings and conferences (34 presentations in all) and the project has been highly visible in media with a number of popular science articles, videos and blogs. The latest in Science and Technology. For an overview of publications and outreach see this section.
The time-lapse video that was made during the Marine Night campaign this last winter was included also as a supplementary material in latest paper on activity of organisms during polar night. Until last week, this video lived a quite and rather anonymous life on YouTube, where just a little bit more than 2000 people had watched it. But that was until our paper was highlighted by the BBC New last week. Following this exposure, the video was posted on the BBC Science News Facebook, and within just a few days more than 3 million people had watched the wonders of the polar night. And the number is still growing (although, currently, not that rapidly), translated into Turkish, Russian and Arabic and placed in their YT channels, shared 8000+ times and got very interesting comments including the ones concerning politics, religion or even water on Mars... Probably one of the best (it got also the greatest number of answers), was the question: “Why did the snake lie in the same position for 2 days ?” ...and maybe “But, is the fish ok?” All this created so much noise that e-mails started to show up and Thomson-Reuters and Weather.com want to use this video…

Following the combined CircA - Marine Night - Arctic ABC meeting in Oban in May, a news story appeared in the BBC news based on the exciting and strong collaboration between The Scottish Association for Marine Science (SAMS) and Norwegian partners. Together with the FAABolous project lead by Dr E. Leu at APN, the story focus on the start of our two new projects and the role of SAMS as a key partner. You can find the news article here and the radio programme here (starting at approx. 16:45)
outreach tab. A meeting summary can be found here.For one week, from 1-5th of June 2015 the three ARCTOS and Mare Incognitum projects CircA, Marine Night and Arctic ABC hosted a meeting at SAMS. For CircA, this is the last project meeting, as we are now well within our final year. The meeting was therefore primarily aimed at writing up papers. For Maine Night, the meeting is a midterm meeting that marks the transition from a field campaign phase to a writing phase. The main aim during the meeting was to inform each other as to where we are following the two large field campaigns that have been hosted in Kongsfjorden January 2014 and 2015, and to prepare a plan for writing up papers. For Arctic ABC, this was a kick-off meeting during which we discussed and planned the ice tethered observatories.

Diel vertical migration (DVM) of zooplankton is a characteristic feature of the world’s oceans and lakes, and has been claimed to be the largest synchronized movement of biomass on the planet. Since the phenomenon was first detected almost two centuries ago (in 1817), there have been numerous studies into both the adaptive significance of this behaviour and its ecosystem consequence. A migration of animals to the surface layer at night allows zooplankton to feed in food-rich waters with reduced likelihood of detection by visual predators (predator-avoidance hypothesis), whereas during daytime they seek refuge in the darkness of the deep. The period around equinox, when the day and night are equally long are known to be a peak period for this type of migration, as it holds a significant advantage to each individual to be able to hide away down in the deep during the bright day and to migrate up in the surface waters during the night to feed on the many small algae and smaller zooplankton that live there. Predators in the pelagic generally use two main feeding modes; they either search for prey using vision (visual predators, e.g. many fish, birds and large zooplankton) or they search for prey by sensing vibrations and movements (tactile predators, many zooplankton). As a result, the prey encounter of visually searching predators is tightly bound to the light regime and prey encounter will be a function of day and night, time of the year and latitude. The extreme seasonality of high latitudes, including the polar night, creates a unique research laboratory for our endeavours to understand the relative roles of different prey encounter modes and for the functioning and constraints of visual predators in the north. To read more about the results, see these recent articles (Norwegian/Icelandic) , or wait for the story to appear in a scientific journal or other media soon..!
Back when the Vikings ruled, blue mussels had a natural habitat in Svalbard. They disappeared when the climate cooled, but today blue mussels have re-established themselves at 78 degrees North. The Svalbard blue mussel is thus a clear and present climate indicator of a warming Arctic. The reappearence of the blue mussels is in the focus of the Marine Night PhD student Peter Leopold. At several occasions the topic has been in the media recently:
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".
After another successful Marine Night campaign in Ny-Ålesund concluded, the nightly activities were brought to a wider public by national and international outreach activities. Check out the following links to learn more. A complete list, also of earlier publications, can be found on the project page.

The Polar Night exhibition will also go on an international tour in the near future. In May parts of the exhibition will be shown during a festival at the Smithsonian Institution's National History Museum in Washington and Anchorage, USA.
In addition to these outreach activities, there has also a special issue of the scientic journal "Polar Biology" been published. All articles therein are available as open access.
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.
Soon the exhibition will also be shown in the USA, at the Anchorage Museum and in part at the Smithsonian. More details soon!
