Eli Kintisch who joined the Polar Night cruise in January 2018 has published three episodes on climate change, featuring UiT and SAMS researchersMore...
During the UNIS/Arctic ABC cruise in Svalbard in late August the moorings that were set out for the FAABulous project were retrieved. Unfortunately, one was lost – probably due to strong currents close to Akselsundet, but on the remaining ones, everything seems to have worked out as planned, and we are looking forward to deal with a unique dataset during the coming months. Great thanks to Daniel and Finlo (and everyone else involved in these operations).

The Mare Incognitum family is glad to announce that Laura Hobbs, a former PhD student in the recently finished CircA project, has been named Postgraduate of the year! Dr. Hobbs has been a PhD student at the Mare Incognitum partner SAMS in Oban, Scotland, and receives this award by the University of the Highlands and Islands. She has been nominated by her former supervisor Dr. Finlo Cottier, who is also part of several Mare Incognitum teams. During her project, Laura focused on the mysterious activities of Arctic zooplankton during the polar night. For more infomation please have a look at the CircA project page and visit SAMS. You might also want to check out the excellent publication on the mysteries of zooplankton moonlight migration.
The FAABulous project (studying Future Arctic Algae Blooms – and their role in the context of climate change) was this winter/spring challenged by historically little sea ice in Arctic areas, in particular in the European sector, including Svalbard and the Barents Sea (for scientific data on the sea ice extent and the related temperature anomalies check out these sites: https://nsidc.org/arcticseaicenews/, and http://cci-reanalyzer.org/Reanalysis_daily/).
The planned sea ice-based field work had to be cancelled, and we needed a plan B to capture this highly unusual situation that presents us a truly future situation that we would not have expected to experience already now.
Luckily, we got granted cruise time on the coast guard vessel KV Svalbard at the end of April.
We went to the almost completely ice-free van Mijenfjorden to take samples of phytoplankton and zooplankton, as well as CTD data along a transect from the innermost part of the fjord until the fjord mouth. We found a strong diatom-dominated spring bloom in the outermost part of the fjord, while the water temperature in the inner basins was still below 0°C, and the chl a concentrations were very low.

Last week, participants in the two projects gathered in Tromsø for the second ABC meeting. This year, the meeting was organised in two parallel sections: While the technology group spent the entire week in Tromsø, testing out equipment in an ice covered lake outside Tromsø (there was no sea ice left in Ramfjorden, so we had to move operations to a lake instead), the entire group met for a two-day meeting (Summary minutes PDF). The main purpose of the meeting was to ensure that the development of the ice tethered observatories - ICE-POPEs (ICE tethered Platform-cluster for Optical, Physical and Ecological sensors) - is under control and according to plan. And so it is!
Up with a tree in Rijpfjorden came a new and surprising inhabitant - a shipworm. Until now we have basically assumed that this group of organisms does not occur in Arctic waters. This new and exciting finding have important implications both for our understanding of the local benthic fauna and not the least for preservation of known and hitherto undiscovered wrecks along the coast of Svalbard!
From 8-24 January 2016 the 5th consecutive Polar Night cruise with RV Helmer Hanssen took place. As in previous years, the cruise took place in Svalbard waters. The scientific program started in Isfjorden before Helmer Hanssen brought us north to Smeerenburgfjorden, Rijpfjorden and close to the ice edge to 81 N. The second leg of the cruise focused as in previous years on investigating processes in Kongsfjorden. We did not encounter any landfast or drift ice during the cruise. This Polar Night cruise was mainly a contribution to two Mare Incognitum projects: Arctic ABC and Marine Night, as well the UiT master course BIO-8510 ARCTOS - Marine ecological research cruise to Svalbard. The scientific program included sampling zooplankton, benthic and fish communities using traditional methods (nets, trawls, grabs and box corer) as well as applying modern technologies such as the Acoustical fish and zooplankton profiler as well as a number of optical methods (Video Plankton Recorder, Laser Optical Plankton Counter, under water bottom camera, ROVs and hyperspectral imaging systems). In addition to the biological program, marine archaeological research was conducted in Isfjorden and Smeerenburg using automated under water vehicles (AUV) and ROVs equipped with imaging systems. We were also very successful in deploying a Jetyak (automated kayak). Equipped with optical and acoustical sensors the Jetyak can do measurements further away from the research vessel thus conducting measurements of light and vertical migrations of zooplankton in areas undisturbed by light emitted from the boat. A lot of great discoveries and new insights into the secrets of the polar night were gained – some of which will appear in media in the weeks to come (see links below), others in scientific journals later in the year or next year. Overall, the cruise was very successful with all planned sampling running smoothly and the weather being cooperative.
Werewolves have become known as the pets of the polar night researchers. Both in the CircA and in the Marine Night project much attention was paid to their behaviour and how the lunar cycle affects their behaviour. A newly published paper under the lead of Kim S. Last in Current Biology sheds some (moon-)light on these mysteries. The paper is accompanied by a “behind the scenes” video produced by SAMS. You can download the paper “Moonlight Drives Ocean-Scale Mass Vertical Migration of Zooplankton during the Arctic Winter” (Current Biology 26, 1-8, 2016) here (open access) and watch the video below or in Youtube here. The paper had a massive media impact, include mentions in the New York Times and New Scientist. A comprehensive list of all media coverage can be found in the CircA publications and outreach section.
Studies carried out on a wide variety of Arctic species during the polar night reveal continued feeding, growth and reproduction, changing our view of this period from one of biological stasis to a time of continued high activity levels. Prof Geraint Tarling from the British Antarctic Survey use his experience as a polar researcher to place the recent findings from the polar night (Berge et al 2015 in Current Biology) in a wider context.

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…
