Read MoreAfter a period with focus on data collection, sample analyses, and model-based investigations and predictions, it is time to merge and integrate new knowledge across approaches and key themes. To do so, seven overarching themes have been identified and task force groups have been initiated in the project Nansen Legacy.
Read MoreAfter two years of digital meetings the board at Nansen Legacy finally could meet in person at the Nansen Legacy board meeting in Tromsø today.
Read MoreIn June and July 2022, heatwaves struck Europe, North Africa, the Middle East, and Asia, as temperatures climbed above 40 degrees Celsius in places. Less known is that heatwaves also occur in the ocean. Like heatwaves on land, marine heatwaves have the potential to devastate ecosystems and cause large economic losses in fisheries, aquaculture, and other marine ecosystem services, calling for an increased focus on and understanding of the occurrence and impact of marine heatwaves.
Read MoreThe interplay between mercury and manganese in Arctic seawater may explain a surprising drop researchers found in mercury levels in the Barents Sea during the winter.
Read MoreGood science is created by the interplay of different thoughts, work approaches and data. This is why collaboration with scientists around the World is essential for the Nansen Legacy. After years of pandemic and travel restrictions, the project is happy to see that an increasing number of its scientists are now spending time abroad working with scientists from other countries and research fields on Nansen Legacy samples and data.
Read MoreIn many Arctic regions, sea ice retreats northwards. This often moves the ice edge zone from relatively shallow waters on the continental shelf to several kilometre deep waters in the central Arctic Ocean. Implications of this displacement for organisms living at the ice edge are largely unknown. Scientists from the Institute of Marine Research have studied harp seals, which’s icy habitat has retreated from shallower to deeper waters north of Svalbard over the last 30 years.
Read MoreThe Nansen Legacy is in its fifth year and looks back at over 350 days out at sea. The extensive field campaigns over the last years have generated unique abiotic
Read MoreArctic sea-ice plays a pivotal role in the Earth’s climate system and its loss may accelerate the rise of global temperatures. Understanding the future state of sea-ice is therefore a prerequisite for evaluating the development of the World’s climate. Now scientists of Norway’s largest Arctic research project – The Nansen Legacy – have looked into both the past and the future to unravel the question of future sea-ice state in the Arctic.
Read MoreNTNU researchers from AMOS, the Centre for Autonomous Marine Operations and Systems, used small satellites and subsea robots — and everything in between — to study marine life in Svalbard’s Kongsfjorden in a first-ever experiment in May.
Read MoreGraphical abstracts, infographics, one-slide posters for digital conferences – the way scientific results are presented nowadays requires increased design and illustration skills. This is why the Nansen Legacy organized a
Read MoreNansen Legacy’s side event “From Science to Policy to Impact in the Arctic” on the last day of the Arctic Frontiers conference was a full success!
Read MoreHow can we keep track of all the data we collect in the Arctic? Watch this video to see how we do this in a consistent and standardized way that makes publishing our data easier.
Read MoreClimate warming is changing our seas and their biodiversity. In the high north, the loss of sea ice and temperature rise favor southerly species, which colonize Arctic marine ecosystems. Arctic species suffer the ongoing changes in the environment and are threatened by incoming species which eat them or their food
Read MoreHalf-way through the Nansen Legacy project, 2021 was the year to take stock and to catch up.
Read MoreThe Nansen Legacy is home to over 30 PhD students. On April 22, Elliot Sivel (IMR/UiT) was the first of the Nansen Legacy PhD students to defend his work. The evaluation process included both a trial lecture on modulation of species interactions by environmental and anthropogenic stressors, as well as the dissertation defense presentation entitled ‘Investigating the drivers of the Nordic Seas food-web dynamics using Chance and Necessity modelling’.
Read MoreThe Arctic Science Summit Week (ASSW) 2022 took place in Tromsø 26 March to 1 April 2022 and scientists from the Nansen Legacy contributed in various ways.
Read MoreNansen Legacy has reached and passed the magical number of 100 publications! Congratulations to all scientists who have contributed. What are actually these publications about, where were they published and
Read MoreThe floor vibrates and a crushing sound fills the bridge as the Norwegian research icebreaker Kronprins Haakon breaks through the sea ice. At 87°N and 17°W, north of Greenland and
Read MoreEver wonder how the ocean reserves as much dissolved organic carbon as atmospheric levels of carbon dioxide? The truth is I do not have the answer to this question. Merely this question is what captivated my interest in this topic. How is it that nature maintains this immense carbon capture system and we still can´t figure out exactly how it functions?
Read MoreOur names are Megan Lenss and Evan Patrohay, and we are joining the most recent Nansen Legacy cruise as US Fulbright Scholars. Fulbright, a program through the United States State Department, has granted us funding to complete yearlong research projects in Norway.
Read MoreSince 2018, the Nansen Legacy consortium has successfully completed 16 ship-based expeditions into the Barents Sea. They have provided state-of- the-art new knowledge on Barents Sea physics, chemistry and biology across different seasons and oceanographic regions. This new knowledge achieved is needed to assess potential impacts of a changing marine system and to continue the sustainable use of the rich marine resources like cod, which is part of the key mission for Nansen Legacy.
Read MoreThe heat transport into the Nordic Seas has increased steadily in volume and temperature over the last century, according to recent study.
Read MoreIn a big project as Nansen Legacy a lot of samples are collect and even more data are produced. Good data management is therefore highly important. Only when data are archived in a good way, they can be made available to all project participants, shared with other scientists, and preserved for the next generation of researchers.
Read MoreA major goal in the Nansen Legacy project is to educate a new generation of Arctic scientists. In 2021, five Nansen Legacy master students finished their degrees. Congratulation to all of them for a very successful work in the fields of oceanography, marine biology, and geology.
Read MoreAn international panel of experts has assessed the Nansen Legacy project and states in their report that they are very satisfied with the progress and research results midway through the project period.
Read MoreNovember at 79 or even 81 N is pretty dark. The sun has disappeared for winter a long time ago, and all that is left is a bit of twilight at noon. For the phytoplankton in the sea that means that there is not enough sunlight to grow. For us, out on a research cruise to service instruments that were deployed north of Svalbard and in the Barents Sea last year or the year before, it means that we struggle to see! Most of the day, it is pitch black dark, especially if it’s new moon as at the start of our cruise. The ship itself is lit up like a Christmas tree with lots of light especially on the work deck in the aft, which often makes seeing anything out at sea very difficult. Light on the bridge is therefore always dimmed and only red light is used when needing a bit more illumination.
Read MoreAn important pathway from knowledge to users goes through national and international science synthesis and assessment initiatives where expertise merges and extracts relevant scientific results to address societal needs for knowledge. Nansen Legacy scientists – especially those working in the management institutions among the project partners – have contributed to several national and international status- and management reports on the ocean and climate state in 2021. This ensures a direct transfer of the new knowledge generated by the Nansen Legacy project into assessment reports used for knowledge-based management and policy making in Norway and the World.
Read MoreAfter a very busy year in the project (six cruises, ongoing sample analyses, a rising number of publications), we are glad to announce that also the Nansen Legacy newsletter is finally running again.
Read MoreIt is November, polar night, and almost winter – must be time for a cruise to the Arctic Ocean to collect instruments and equipment for our project!
Read MoreEdson Silva just published his first article as part of his institutional PhD project – congratulations! Together with five other co-authors from NERSC and one from the University of Bergen (UiB), he studied the annual cycle of phytoplankton/algae blooms in the Nordic Seas by utilizing satellite data from 2000-2020.
Read MoreAfter four seasons and four exciting research cruises, I finally finished my PhD field work
Read MoreThe Nansen Legacy is home to more than 70 early career scientists. These young and dynamic researchers are a core element of the project, and present the next generation of Arctic researchers, consultants, policy makers, teachers, communicators, or other resources in society. Hence, the Nansen Legacy thrives to support its early career scientists in forming a strong and supporting network. The annual Nansen Recruit Forum is an essential element in this work.
Read MoreThe Nansen Legacy disposed over 350 days of ship time to ensure high-resolution sampling of physical, chemical and biological parameters of the ecosystems of the northern Barents Sea and the adjacent Arctic Ocean.
Read MoreSatellites aid researchers with important information on environmental state and processes. Yet, essential empirical data of the Arctic marine environment cannot be collected from space. Ship-based measurements are in many
Read MoreArctic marine research is really exciting, and one could make blockbuster movies, or a tv-series based on research expeditions, such as those within the Nansen Legacy project. The logistics around planning and executing research cruises when going into the sea ice of the Barents Sea are enormous, but probably not that exciting when thinking about film material. However, simple things such as the safe arrival of our samples in Bergen following the completion of a long cruise are very special to us. Still, when aiming to make an Arctic marine science tv-series one should focus on the research cruises and the samples taken. The different cruises could represent the episodes of the series and the samples that we are taking might well be the characters of the series. I guess everyone agrees that if you want to understand what is going on in the series (the Arctic marine ecosystem) you should not miss out any episodes or only shoot with half of the cast.
Read MoreLast week in October, the Nansen Legacy was finally able again to host a physical annual meeting. After almost two years with virtual meetings, it was a great pleasure to gather 160 scientists to present and discuss science in person.
Read MoreImportant groups of calcifying zooplanktons (planktic foraminifera and shelled pteropods) were examined under the sea ice cover to see how they cope with changes of physical and chemical properties in the Arctic Ocean, such as ocean warming and changes in carbonate ocean chemistry during the polar night in December 2019. They are doing well!
Read MoreMarine heatwaves, ecosystems shifting and sea ice melt are just some of the many topics on this Nansen Legacy annual meeting in Trondheim. The Nansen Legacy is now halfway into the 6-year project and are now moving into a phase with more focus on results for all disciplines.
Read MoreOn the JC2-2 cruise we are visiting the deep basins of the Arctic Ocean. The goal of my team is to conduct experiments with animals from the bottom of those basins, which means keeping deep, Arctic animals alive. If deep-sea diving is an extreme sport, then this is definitely extreme science.
Read MoreThe Arctic Ocean is composed of different layers organized on the vertical, and these layers have different temperature and salinity properties. A cold and fresh surface layer caps a warm and salty layer of Atlantic Water. The heat contained at depth (about 300m) in the warm and salty Atlantic Water could melt the entire Arctic sea ice cover if it reached the surface. It does not happen because the cold surface layer caps this Atlantic layer quite well and keeps it at depth. However, in some regions, such as north of Svalbard, sea ice melts in summer even though it is -30 outside. How is that possible?
Read MoreHave you ever watched the colors of the sunset over the sea – then suddenly the beautiful moment is gone, and darkness surrounds you. Arctic sea ice is like that
Read MoreAfter a long period of not being able to meet up and be together, people welcomed the possibilities to aquire knowledge and attend as an audience at a social event at their local pub. In four cities, 16 speakers participated with lectures about their research work in the Arctic Ocean.
