All of the projects which were operating under the Mare Incognitum umbrella are finished by now. Mare Incognitum was never a project in itself, but rather a platform to showcase ongoing cooperating projects by giving them a platform to post news, links, publications and the team members. The original pages could not be maintained any more, due to and outdated content management system (CMS) which could not be updated. Migrating to a new system takes time and was low on the priority list, but now it is finally happening. We have swapped from Joomla to WordPress as our CMS of choice, which we will slowly populate again with content. The information from the old pages will eventually also be transferred, but it will take some time.
Still producing data (and news) is the infrastructure part of ArcticABC and the Kongsfjorden-Rijpfjorden Observatory Programme (KROP). New projects will also be able to use this umbrella to showcase their activity.
In the meantime, you can find parts of the old web pages in the Internet archive of the WayBack machine here.
We were lucky enough to get ship time with UiT’s research vessel Helmer Hanssen this autumn, despite all the social distancing restrictions. With a scientific crew consisting of only 13 people we went from Tromsø to Svalbard to service the ocean observatories (KROP) in Kongsfjorden and Rijpfjorden, maintain the photographic benthos time series in Kongsfjorden, Smeerenburg and Isfjorden, and to conduct some experimental work for CalAct. Everyone was happy to get out of the (home) office, the sea was mainly calm, and best of all: the Rijpfjorden mooring was still there! Ice conditions in 2019 made it impossible to get into Rijpfjorden last year, and the lost of the Kongsfjorden mooring due to corossion last year had made us a bit anxious, but the retrival was successfull and 2 years of data have been recorded!
In July 2019, a set of ArcticABC ice tethered observatories (ITOs) got deployed from R/V Kronprins Haakon at about 84°N. The ITOs consisted of an Acoustic Zooplankton Fish Profiler (AZFP), a Sea-Ice Mass Balance Array (SIMBA), an automated weather station (AWS) and the newly designed high-sensitivity Light & Temperature chain (LT-ITO). During the drift, the SIMBA, AWS and LT-ITO were unfortunately lost at some point. Their data is safe though, as it was transmitted by Iridium. The AZFP data was successfully downloaded by a data harvesting plane with the help of a broadband radio, only a short time before the AZFP-ITO was washed ashore on the northern coast of Iceland. The surface buoy has been recovered by Icelandic SAR, but the AZFP is unfortunately lost. We have the position of an object in the water closed to where the unit beached itself, which we will check out once the Corona restrictions are eased.
Mare Incognitum is an umbrella platform to showcase ongoing projects of researchers at UiT The Arctic University of Norway with other institutes and universities in northern Norway and across the globe. Mare incognitum provides a platform to post news, links, publications and to present team members. The site is maintain by the research group of Prof. Jørgen Berge at UiT, Tromsø, Norway.
