ARCTOS - Arctic Marine Ecosystem Research Network
PolArt 2013 opening Friday 18.01.
For several years ARCTOS has cooperated with Tromsø Kunstforening (Tromsø Center for Contemporary Art) in a project that brings young artists and researchers together. They travel together on research cruises to the Arctic, mostly around Svalbard. Impressions of these trips are the basis for their pieces of art which are presented at the PolArt exhibition January/February. The opening is in connection to the Arctic Frontiers conference on Friday, 18.01. The exhibition is open Wednesdays to Sundays until February 24th. The 2012 artists - and 2013 presenters - are Christian Bermudez, Sigbjørn Bratlie and Helene Sommer.
New ARCTOS PhD: Anaïs Aubert
Already some weeks ago, on December 10th, we could celebrate another PhD defence. Anaïs Aubert successfully defended her thesis titled: "Stoichiometry of lipid synthesizing calanoid copepods in Arctic and sub-Arctic marine regions" at AMB/UiT. The thesis focuses on the effects of elemental requirements of Arctic copepods by investigating changes in C:N:P ratios in three papers, two published and one in review. Anaïs' supervisors were Paul Wassmann (UiT) and Tobias Tamelander (UiT). We wish Anaïs all the best for her future carreer!

New Russian-Norwegian cooperation project: COOPENOR
COOPENOR is a newly financed project under the NORRUSS programme (NRC) within the ARCTOS research network that will start in January 2013 and last for 3 years. The project “COmbined effects Of Petroleum and the Environment in bivalves from the NOrwegian-Russian Arctic” will be led on the Norwegian side by Dr Jasmine Nahrgang at the University of Tromsø and by Dr Igor Bakhmet from the Institute of Biology of the Karelian research Centre on the Russian side. COOPENOR is a collaborative effort between four Norwegian, five Russian, one French and one USA partner institutions will include two PhD students. The overall objective of the project is to provide new knowledge that will enhance the implementation of comparable tools and protocols for marine monitoring within the Norwegian and Russian sectors of the Arctic by using two well-known benthic indicator species (blue mussel and Icelandic scallop).
New ARCTOS PhD: Hildur Petursdottir
On Decembert 3rd, ARCTOS PhD student Hildur Petursdottir defended her thesis with the title "Trophic relationships and the role of Calanus in the oceanic ecosystems south and north of Iceland" at AMB/UiT. The thesis cotains five published papers (see list below). Hildur's supervisors have been Marit Reigstad (UiT), Stig Falk-Petersen (UiT/AMB) and Astthor Gislason (Marine Research Institute Reykjavik). Hildur has returned to her home institute on Iceland. We say congratulations for the successful PhD defence and hope to see you again here soon!

UNIS extended admission for spring 2013 courses
The ARCTOS member institute UNIS has extended the admission for all spring 2013 courses, which means also the courses most relevant for ARCTOS members: AB-203 Arctic Environmental Management and AB-204 Arctic Ecology and Population Biology. If you are teaching undergraduate students this autumn, you might want to draw their attention to this opportunity to study the Arctic while actually living there. Places are given on a first come, first serve basis.
Public talks in natural science, University of Aarhus, Denmark
Offentlige foredrag i Naturvidenskab is the title of a sequence of public talks at the University of Aarhus to which the ARCTOS member Paul Wassmann was invited to. In concert with our colleague Ronnie Glud two talks were presented regarding the dramatic changes in the Arctic. Paul took a birds eyes view while Ronnie presented the results of a major study of an east Greenland fjord, Young Sound. A public talk is generally not a major issue, but the talks at the University of Aarhus are. They are surprisingly popular. More than 3000 people listened to the talks regarding the Arctic Ocean. Tickets for the talks disappear in days. The demands are so strong that the biggest lecture hall is not sufficient and 4 additional halls are used. The talks are presented there with a video link. The spread in age is also surprising, from pupils to retired people. Many come directly from their work and the cantina is open to those, offering a high-qulity buffet. In the break coffee, wine, beer and snacks are offered and even popular books are on sale. During the talks there is a complete silence in the audience. After the lectures a natural science museum opens for the visitors and here they can meet in person the speakers.
Behind this arrangement stand Peter Bondo Christensen and Jens Dybkjær Holbeck, both scientists that have developed a strong interest for outreach. The speakers are guided in detail under the preparation of their talks. All slides are scrutinized prior of a trial lecture where everything associated with a talk (quality of wording, the manner you talk, the way to stand, the way you approach the audience through examples etc.) is commented, criticized and suggestions made. And it does not end there. After each lecture new suggestions pop up and each time the talks is improved. One has the impression that one delivers a performance, rather then a talk.
To be invited to speak under such circumstances was a tremendous experience. In order to study the concept closer and to declare an interest in joint research in the Arctic, dean Edel Elvevoll of UiT as well as the head of the research department, Linda Hamrin Nesby, visited the University of Aarhus. The experience has provided inspiration for outreach could be carried at UiT.
ARCTOS organises the 3rd pan-Arctic symposium
Pan-Arctic integration of marine ecological investigations in the Arctic Ocean and their entanglement in physical and climatological studies has been an important element for the ARCTOS network. The first meeting took place 10 years ago and gave rise to the volume Structure and function of contemporary food webs on Arctic shelves: a pan-Arctic comparison. Progress in Oceanography 71: 123-477, edited by P. Wassmann (2006). The second pan-arctic meeting took place in Tromsø in 2009 and resulted in the volume Arctic Marine Ecosystems in an Era of Rapid Climate Change. Progress in Oceanography 90: 1- 131, edited by P. Wassmann (2011). The third pan-arctic symposium took place in October 2013 in Motovun, Croatia. 34 specialists in arctic oceanography and marine ecology met for 5 days. Overarching perspectives of contemporary and future ecosystems in the Arctic Ocean was the title of the symposium that focussed upon 15 invited talks.
The idea behind the 3. Pan-Arctic symposium is the perpetual need to integrate the pan-Arctic research endeavours. The last International Polar Year was an excellent possibility to overcome the political difficulties of the Cold War that froze also international research cooperation in the Arctic. It was followed by the claims of the Arctic 5 through UNCLOSE and while this is a predictable and peaceful process the international situation in the Arctic is still characterized by flag waving.
We experienced a most successful meeting, high-quality talks and extensive discussions. We can now see the contours of of a new age of arctic research where we can switch over from case studies inside the frame of the various regions to the pan-arctic perspective where the entire Arctic Ocean appears in our imagination and understanding.
Catching a ride with deep Atlantic currents?
Recent data show that we face a historical and dramatic decline in the Arctic summer sea ice extent. This is generally believed to be very bad news for marine organisms living under the ice. However, new research shows that at least for some of the species there might be some hope, as they may actually have evolved adaptions towards ice free summers. The scientists call their hypothesis the “Nemo hypothesis”. Data for this hypothesis, which was recently published in Biology Letters (open access PDF), was collected during the ARCTOS Polar Night Cruise (Bio-8510).

POLARISATIONs first field and experimental season!
The POLARISATION team has been working hard these last couple of months to plan and prepare the first round of experimental work: in total 3 experiments over a period of 4 months will be carried out both at the marin Lab in Ny-Ålesund and at the Biological station Kårvika of the University of Tromsø. The team of the newly employed PhD student and post doc and the PI will try to decipher the way oil contaminants enter polar cod, a small Arctic fish, used as a model species, through the diet and affect crucial lipid related processes. In a warming Arctic, with anthropogenic activities moving further north and the risk of oil spills constantly increasing, it is both important and exiting to find out how oil compounds change major lipid related processes such as storage of energy, growth, and reproduction.
Ireen Vieweg (PhD student) is preparing for the first experiment in Ny-Ålesund and will soon be assisted by Dr Jordan Nechev (Post doc) in a long and challenging experiment to study the molecular and cellular effects of oil contaminated food. About 500 polar cod will indeed be taken care of over a 3 months period and fed individually. On RV Helmer Hanssen, Dr J. Nahrgang (PI) is presently sampling as many fish as possible and will return to Ny-Ålesund in less than a week. A main challenge will also be to return a stock of live fish to the Biological station of the University of Tromsø (Kårvika) to carry out a new set of experiments focusing on uptake and tissue distribution of oil contaminants and the formation of toxic metabolites as well as the implementation of in vitro tissue cultures.
