February 2017 CarbonBridge contributes to childrens activities on living sea ice

CarbonBridge scientists, Lena Seuthe, contributed to a children’s museum event as part of the exhibition “Living sea ice” at the Polar museum in Tromsø. Nearly 60 kids and their parents conducted simple hands-on experiments on the structure and formation of sea ice, as well as sea ice as habitat for various plants and animals. Play doh and other materials were used by the children to sculpture plants and animals found in Arctic sea ice.

December 2016 CarbonBridge visits elementary School

Do you know how many plants and animals you swallow each time you get some drops of seawater into your mouth while swimming in the sea?, asked CarbonBridge scientist, Lena Seuthe,  the first grade at Sandenessund elementary school in Tromsø.sandnessundskole_desember2016a

With help of mircoscopes, the kids discovered tiny living plants and animals in drops of water, observing their different svimming and feeding behaviour. 

During the following art class, the pupils drew, coloured and clipped their own plants and animals living in drops of seawater.

December 2016 CarbonBridge back at Tromsø’s childrens university

barneuni1Nine month after its first contribution, CarbonBridge was back at Tromsø’s childrens university. This time, CarbonBridge scientist Elisabeth Halvorsen and Lena Seuthe, talked about the World’s fatest animals, which are in contrast to common belief not cheetahs or peregrines, but small crustaceans (copepods) living in the sea. These crustaceans are highly abundant in the World’s Ocean, where they play a key role in transferring energy from plants up to higher trophic levels, such as fish. Given their importance, these crustanceans were extensively studied within the CarbonBridge project in the waters north and northwest of Svalbard.

Tromsø children’s university is a cooperation between the UiT- The Arctic University of Norway and the central library in town, aiming at conveying research at UiT in an easy and fun manner to kids of 7 to 12 years of age.

November 2016 CarbonBridge scientist receives research award

achimrandelhofframprisenCarbonBridge PhD student, Achim Randelhoff, received this year’s Fram Center award for best research. The jury emphasized that Randelhoff has worked highly interdisciplinary and by that filled essential knowledge gaps in our understanding of Arctic marine productivity.

Randelhoff works on the turbulent mixing and vertical nitrate fluxes in ice-covered Arctic waters, and has contributed with new understanding to mechanisms confining primary production in highly stratified waters. ___________________________________________________________

October 2016 CarbonBridge team wines price for its outreach

The CarbonBridge team contributed to this year’s research days with a stand at the science fair of UiT-The Arctic University of Norway, and won the price for best science fair stand 2016.

Studiestart Campus TromsøJoining in on the general theme, “Boarders”, of this year’s research days, CarbonBridge designed a suite of easy experiments on the visible and invisible boarders found in the Arctic Ocean. The ice edge was chosen as a very visible Arctic boarder, discussing its dynamics and retreat. Special focus was given to the impact of melting sea ice on the formation of invisible boarders between fresher ice melt water over saline seawater. Visitors could test this effect in an easy hand on experiment with seawater and colored ice cubes. The impact of such water column stratification on algae growth in the sea was discussed, and algae shown to the visitors through a microscope.

usynlig_grense

As CarbonBridge is concerned with the impact of warm Atlantic water on stratification and algae production in the Arctic, the stand also embraced an experiment on the potential of warm water to deteriorate water column stratification.

September 2016 CarbonBridge PhD course on The story and impact of Arctic marine science

Arctic marine science is not only about the natural sciences, even though that is what we work with on a daily basis. However, the increased societal interest and focus on the Arctic increasingly challenges natural scientists with demands on Arctic related questions that reach far beyond their field of natural science. Therefore, CarbonBridge gathered experts from various academic fields for a PhD workshop to address and discussion questions, such as In which tradition do we conduct our science in the Arctic? Are we part of an Arctic heroic story told to the public? Which role do we as natural scientists have in society? Is the research free from political influence and industrial interests?

p1010064The PhD course gathered 6 students from different fields of natural science and resource economics, 8 lecturers, and interested guests who followed presentations and participated discussion on issues covering four main themes including a) Historical perspectives, b) The Arctic image, c) Science communication and d) Is science politically independent?

The lecturers included in marine biology Prof. Paul Wassmann (UiT), in marine microbiology Prof. Frede Thingstad (UiB), in literature Prof. Johan Schimanski (UiO), in marine resource management Prof. Petter Holm (UiT), in fisheries management Prof. Bjørn Hersoug (UiT), in geology and writing Prof. Henrik Svensen (UiO),as well as director at the Polar Museum, Lena Aarekol (UiT), and senior scientist in environmental philosophy and ethics, Fern Wickson (Genøk).

The students elaborated on the themes through writing of a reflection text, presentation of posters with feedback from the group, participation in discussions and finally through production of a blog text on a science topic of their own choice.

June 2016 CarbonBridge meets Dark Ecology and Arctic Encounters

How does the sea ice come to matter? That was the question for a debate on Verdensteateret in Tromsø, where art-, social science- and natural science perspectives met to explore the ice edge. Or isn’t it rather a seasonal sea ice zone that matters? Sea ice has become a strong symbol of Arctic responses to climate change and is has also become an important tool for governments in regulating or allowing activities in the north.

The discussion revealed the facet of perspectives on sea ice when CarbonBridge PI, Marit Reigstad and colleague Prof. Bodil Bluhm shared thoughts and experience from ice-covered waters with post doc in political science and political geography Berit Kristoffersen (UiT and Arctic Encounters), curator Hilde Methi (independent curator, and Dark Ecology, Kirkenes), and artist Jana Winderen (exploring hidden depths and sources and like water and ice through sounds, Dark Ecology), just back from a UiT cruise to the Barents Sea.

The arrangement was organized by the two projects Arctic Encounters and Dark Ecology, exploring how objects, landscapes and seascapes in the Arctic matter ethically, politically & aesthetically. The arrangement featured key thinkers, curators, artists, artwork and short films to create dialogue about the Anthropocene, the ice-edge, indigeneity and much more.

April 2016. Stakeholders interrested in CarbonBridge’s primary production estimates

To understand the impact of climate change on sustainable fishproduction, the response at the basis of the food web, namely primary production, is a key.

CarbonBridge was therefor happy to provide input from our project work to a presentation held by Prof. Michaela Aschan on Kystens hus, April 27. The presentation was a part of a seminar series where the science community presents relevant research to users living from or with the sea.

CarbonBridge is glad to note that through our different appraoches to address productivity and fate of production in the Arctic, seem to produce information that is of great interest to users and stakeholders

April 2016. CarbonBridge’s preschool science project on local radio and TV

NRK_barnehagen

CarbonBridge’s preschool science project has lately received attention on Norwegian broadcasting, both on radio and television.

The project is progressing well, with the kids filtering seawater weekly. Last week’s sampling showed the first clear signs of spring in the sea. The kids not only observed some greenish color on the filter, but also observed long diatom chains under the microscope. On land, the snow still covers much of the ground. So, the kids start to suspect that spring might come earlier in the sea than on land.

March 2016. CarbonBridge starts preschool science project

Picture6

Do you know where it gets spring first: in the sea or on land?

CarbonBridge posed that question to five-year-old preschool kids from Tusseladden friluftsbarnehagen in Tromsø this week. About half of the kids meeting CarbonBridge scientist, Lena Seuthe at UiT – The Arctic University of Norway, were convinced that it is the grass and trees on land which will turn green before small algae start growing in the sea.

The children will find out whether they are right or wrong by filtering seawater and evaluating the color of the particles retained on the filter. As the spring bloom of small algae in the sea progresses, the filter should turn greener. The kids will take pictures of the filters as well as the trees and ground on land. From these pictures, the kids will build a time line of the spring progression on land and in the sea, and find a final answer to where it greens first.

February 2016. CarbonBridge meets SI_Arctic
 
 
Picture1CarbonBridge leader, Marit Reigstad, presented CarbonBridge’s approaches and results of studying primary production in the Atlantic Water inflow region to the Arctic Ocean during the SI_Arctic annual meeting 17 February. This include in-situ measurements, comparison of different ways of measuring primary production and a discussion of what information they provide, model experiments used to address the advective patterns of primary production and export to the Arctic Ocean, as well as large scale modelling of primary production.
 
 
SI_Arctic is a strategic initiative at the Institute of Marine Research, preparing future management for the changing conditions in the Arctic. SI_Arctic has the same regional frame, but focus on larger zooplankton, fish, marine mammals and benthos. SI_Arctic  hence provides a complementary focus on the marine ecosystem and link to the physical environment compared to CarbonBridge, and there is therefore a strong mutual interest in sharing results and information.

October 2015. A wealth of data – CarbonBridge’s sister project “MicroPolar” meets in Banyuls-sur-mer

CarbonBridge’s sister project “MicroPolar” presented it’s data during a three day long meeting in Banyuls-sur-mer, France. CarbonBridge and MicroPolar joined their field work, and collected complimentary datasets. While CarbonBridge focused on the quantification of planktonic biomasses, production and loss rates, MicroPolar focused on genomic descriptions of the investigated plankton communities. Hence, the two projects together have achieved an extraordinary detailed description of the planktonic communities of the Atlantic-fed Arctic Ocean.

August 2015. CarbonBridge data published in Nature

Experimental data obtained during CarbonBridge and other projects have been published in the high ranking science journal “Nature Climate Change”. The authors tested the expectation that CO2-enhanced gross primary production (GPP) may be temperature dependent in the Arctic. The results confirmed that CO2 enhances GPP (by a factor of up to ten) over a range of 145–2,099μatm; however, the greatest effects were observed only at lower temperatures and were constrained by nutrient and light availability to the spring period. The temperature dependence of CO2-enhanced primary production could have significant implications for metabolic balance in a warmer, CO2-enriched Arctic Ocean in the future. The work suggests that a twofold increase in primary production during the spring is likely in the Arctic in the future.

How does the competition for nutrients between phytoplankton and bacteria will change in a future Arctic Ocean influenced by increasing levels of dissolved organic matter running off from land? How do different concentrations of mesozooplankton influence the structure and function of the microbial food web? These are questions CarbonBridge’s sister project “MicroPolar” is addressing in a large scale mesocosm experiment in Ny Ålesund on Svalbard. In total 25 scientists are joining the campaign. CarbonBridge scientists, Camilla Svensen and Lena Seuthe, are part of the zooplankton team, investing micro- and mesozooplankton grazing, defecation and excretion rates.

IMG_2910_1024

Half a year after the last CarbonBridge cruise, 22 project participants met in Italy to present and discuss first data from the 2014 field campaigns. Sample analysis are either completed or well on their way, and hence much of the discussion circled around the question how information should be combined and published. CarbonBridge aims at publishing its core work as a special volume in Frontiers in Marine Science latest by the end of 2016.

January 2015. CarbonBridge scientists present first results

During the scientific part of the Arctic Frontiers Conference in Tromsø, Norway CarbonBridge scientists presented first results from the CarbonBridge cruises in 2014.

Paul Wassmann (UiT – The Arctic University of Norway) talked about “The contiguous domains of Arctic Ocean advection: trails of life and Death”, where he demonstrated that the central Arctic Ocean is not isolated, but tightly connected to the northern Pacific and Atlantic Oceans.  In his review, Paul Wassmann presented information about the advection and fate of zooplankton in the Arctic Ocean, now and in the future.  He characterised the various organism types that interact along the contiguous domains and showed how life derived from subarctic production regimes fuels life in the Arctic Ocean.  Paul Wassmann concluded that the Arctic Ocean is, at least in some regions, a net heterotrophic ocean that – during the foreseeable trend towards global warming – will obtain an increased balance between local and advective production and consumption.

Sünnje Basedow (University of Nordland) presented CarbonBridge data on “Advection of Atlantic Water and secondary producers into the Arctic Ocean” together with Arild Sundfjord from the Norwegian Polar Institute. The two CarbonBridge scientists aim to quantify seasonal changes in the inflow of AW and the secondary producers contained therein. For that, data with high spatial resolution were collected along transects across the AW inflow west and north of Svalbard during the three CarbonBridge cruises in winter (January), spring (May) and summer (August) 2014. Water currents were measured along the transects using a ship-borne acoustic doppler current profiler (ADCP) while steaming, and a rosette mounted lowered-ADCP system at stations. Secondary producers were quantified using a laser optical plankton counter mounted on a moving vessel profiler while steaming and on a rosette frame at stations. Production was estimated based on biovolume spectrum theories, and advection of secondary production into the AO was then quantified by combining the high-resolution current and zooplankton data.

Lena Seuthe (UiT – The Arctic University of Norway) talked about “Patterns and drivers of bacterial production in the marginal ice zone northwest of Svalbard”, where she investigated the link between phytoplankton and bacteria in the area studied. Some of the preliminary conclusions are that while bacterial abundance reacts to changes in phytoplankton stock size similar to what is in other areas of the World’s ocean, bacterial production does not increase as fast With increasing primary production as seen in more temperate areas.

______________________________________________________________

December 2014. First scientific results from CarbonBridge presented

Maria Vernet from the Scrippts Institution of Oceanography, US presented first results from the CarbonBridge cruises during the “Arctic Change Conference” in Ottawa, Canada. Under the title ” Coupling of phytoplankton and bacteria production in Atlantic waters west of Svalbard”, Maria Vernet showed rate measurements of both phytoplankton and bacterial growth. Rates of primary production were high both in May and August. Bacterial production was positively correlated with phytoplankton stocks and production rates, but was relatively low in both seasons.

October 2014. CarbonBridge contributes to Science for Schools

SchuleCarbonBridge post docs Elisabeth Halvorsen and Lena Seuthe met high school pupils and talked with them about whether a future ice-free Arctic Ocean could sustain commercial fish Stocks in the frame of the Arctic Frontiers Young program “Science for Schools”. One of the main ideas for the meeting was to give the pupils an understanding of the complexity of marine systems, and why it is not always possible for scientist to give simple and final answers to questions of large socialtial interest.

August 2014. CarbonBridge completes it’s field season with a third cruise

IMG_5235CarbonBridge completed it’s field season with a third cruise to the waters northwest of Spitsbergen. As in May, dense sea ice prohibited RV Helmer Hanssen from reaching  CarbonBridge’s main study area northeast of the Svalbard Archipelago. Nevertheless, all 26 scientists om board were able to gather the samples and data they needed during three 24 hour long process stations and along three oceanographic transects. Now many hundreds to thousands of samples are waiting to be analysed.

———————————————————————————————————

June 2014. Second CarbonBridge cruise successfully completed

CarbonBridge just returned from its’ second cruise to the waters around Svalbard. CarbonBridge aimed at studying physical and biological processes west and north of the Svalbard Archipelago. Dense sea ice prohibited however the research vessel RV Helmer Hanssen from reaching the northern flank, and CarbonBridge was bound to work off the northwest coast of Spitsbergen. Three oceanographic transects were run across the West Spitsbergen Current, transporting warm Atlantic water into the Arctic Ocean. Much effort was put into not only describing the physical properties of the Atlantic water, but also its chemical composition and the zooplankton community advected into the Arctic by this water mass. For this purpose, CarbonBridge used an laser optical plankton counter in combination with a CTD sonde mounted on a moving vessel profiler along all transects.

IMG_9675In addition to the transect work, CarbonBridge conducted three process station in the marginal ice zone around the southern flank of the Yermark Plateau. At the process stations the pelagic community, from viruses to copepods, was studied in detail. Extensive experiments were run to investigate prevailing trophic structures and estimate primary and secondary production. At all three stations, an intensive phytoplankton bloom scenario was encountered, with chlorophyll concentrations of up to 25 µg/L.

May 2014. CarbonBridge celebrates the Norwegian national day in the ice

IMG_2189CarbonBridge left Longyearbyen onboard RV Helmer Hanssen May 15 for its second cruise. For three week 27 scientists from seven nations will investigate the physicochemical and biological structure of the water masses west and north of the Svalbard Archipelago. Tons of equipment are with us on board to allow to investigate in detail all kinds of planktonic organisms, from viruses to mesozooplankton. On May 17 CarbonBridge celebrated the Norwegian national day in its traditional way by eating far too much ice cream, waving flags and singing some happy songs.

January 2014. CarbonBridge completes its first cruise with great success

ctd_mapCarbonBridge’s first cruise aimed at studying the physical and biochemical properties of Atlantic water flowing into the Arctic Ocean during winter. Two oceanographic transects west and north of the Svalbard Archipelago were sampled for water mass characteristics, such as temperature, salinity, nutrients, inorganic and organic carbon compounds, as well as zooplankton distribution and composition in the beginning of January 2014.

In addition to the mapping of water masses, experiments on planktonic organisms, ranging from bacteria to large copepods, were conducted on board to investigate trophic interactions and metabolic processes of planktonic organisms during the darkest period of the year.

November 2013. CarbonBridge scientist conducting Arctic research in southern California

Camilla Svensen, a ”work-package”-leader on CarbonBridge and associate professor in zooplankton ecology at UiT – The Arctic University of Norway, has recently shifted address from the high North to southern California.

As a Fulbright Arctic Chair 2013/2014, Camilla will spend 7 months as a guest researcher at Scripps Institution of Oceanology (SIO) in San Diego.  Fulbright is an organization aiming to facilitate scientific, educational and cultural exchange between the US and numerous other countries. The Arctic Chair Award is available for researchers working with Arctic issues.

During her stay at SIO, Camilla will collaborate with Dr. Maria Vernet on investigating production of dissolved organic carbon (DOC) from Oithona feeding on dinoflagellates. Oithona is a small cyclopoid copepod present in large abundances worldwide, but their role in the carbon cycle is not well defined. The methods developed at SIO will also be relevant for continued investigation of Oithona and other zooplankton species in Arctic ecosystems. Moreover, as part of the Fulbright project Camilla will give lectures and communicate arctic research at SIO and other US institutions. She is blogging about her scientific and cultural experiences at www.sciencenordic.com.

The project has previously received attention at www.forskning.no (in Norwegian):

MicroPolar focuses on the diversity and ecological significance of microbes in Arctic waters, and their influence on biogeochemical cycles. CarbonBridge and MicroPolar were both funded by the Norwegian Research Council in spring 2013 and will share much of their field work around Svalbard in 2014.


September 2013. CarbonBridge kick-off meeting

Discussion_WatersamplingCarbonBridge was officially started at the historical site Skansen in Tromsø the last week of September 2013. CarbonBridge has a strong international component, and among the 25 meeting participants eight nations were presented. Following a presentation of the holistic idea and specific tasks of the project, the practical work started. We planned cooperation and communication around existing time series, utilization of different model types, and practical issues related to the upcoming fieldwork. We look forward to a project with great people, good science and lots of fun.


August 2013. CarbonBridge has gotten a logo

CARBONBRIDGE-LOGOThe project has gotten its logo! The project’s name “CarbonBridge” is a metaphore for the carbon and other nutrients transported into the Arctic Ocean with Atlantic water masses. Quantifying this transport is one of the goals of CarbonBridge. The arrow in the project’s logo stands therefore for the inflow of Atlantic water into the Arctic, depicted by the ice flow entering the logo from the right.
