Oppdagelsen av Jotunfjeldene – En reise inn i geologiens metamorfe verden

Foto/ill.:Billedkunstner: Hanne Åmli.

I 2020 er det tohundre år siden Jotunheimen ble oppdaget og registrert gjennom geologiske beskrivelser, kart og vakre akvareller. Denne utstillingen spør hvordan Jotunfjellene ble til, både gjennom oppdagelsen for tohundre år siden, og de geologiske prosessene som skjedde millioner av år tilbake i tid. I et unikt samarbeid mellom geologene Haakon Fossen (UiB), Henrik H. Svensen (UiO) og kunstner Hanne Åmli, utforskes bevegelsene i jordens indre gjennom kunstens uttrykk. Les mer om utstillingen fra Arena for forskningskommunikasjon. Utstillingen er fra 22.2 kl 10 tom 31.5.2020 kl 17. For billetter til åpningen fredag kl 12 – gratis-billetter her.

Bli med på gratis konferanse for unge geologer og studenter

Young Trondhjemites 2020 er den femte konferansen for unge voksne som studerer eller jobber innenfor geologi. Under konferansen som blir arrangert fredag 27.mars på Norges geologiske undersøkelse i Trondheim, kan du dele din egen forskning, lære av andre og utvide nettverket ditt.

Bli med for presentasjoner, poster-utstilling og en sosial samling på kvelden som inkluderer gratis middag. Det vil bli premiering for beste foredrag og plakat.

  • Vi ser veldig fram til å få finne ut hva unge som studerer eller jobber innenfor geologi er interessert i. På Young Trondhjemites kan mange også bli kjent med flere innenfor sitt fagfelt og kanskje få kontakter som kan være nyttig i forbindelse med en framtidig jobb, forteller Rune Eian, Thomas Hibleot, Graham Hagen-Peter, Jörg Giese og Alf Andre Orvik, som er med i arrangørkomiteen.

Bergen Filharmoniske Orkester musikalsk aften i musikken og vitenskapens ånd – Tema: KLIMA (5.3.20)

Together with the Bergen Philharmonic Orchestra and Borealis – a festival for experimental music, UiB invite you to an evening of extraordinary science dissemination. Part three of the concert series Next Step takes place on the 5th of March in the Grieg Hall with the theme climate.

Some of UiB’s best climate scientists meet the critically acclaimed musicians from the Bergen Philharmonic Orchestra for a magical evening in the spirit of music and science. Together they will take the audience from past climates through our climate today to future climate changes.

The repertoire includes two world premieres of two Norwegian composers, saxophonist Marius Neset and Therese Birkelund Ulvo, and inspirational science dissemination by three researchers at the Bjerknes Centre for Climate Research: Professor Jostein Bakke Department of Earth Science at the University of Bergen, Associate Professor Lea Svendsen Geophysical Institute UiB together with PhD candidate Siri Haugum Department of Biological Sciences UiB.

In the foyer there will be a science exhibition presented by researchers from the UiB and Bjerknes Centre for Climate Research.

UiB employees are offered discounted tickets here:

Are you curious about the background for the concert series and what themes we highlight? You can read more about Next Step here. The spoken language of the event is Norwegian.

Hi, I have recently started in an adjunct position through the Akademia Agreement. My background is also from UiB, where I took my Master and PhD. Since 2012 I have worked in Statoil/Equinor with international exploration and this position has allowed me to do regional work in most continents of the world. Approximately one year ago I moved into the research department where I currently work in the sedimentology and stratigraphy group. My daily work now involves regional studies in South America and the North Atlantic, where we are undertaking tectonostratigraphic analysis of the margins and basins. This work also includes following up and integrating external academic projects and results that are relevant for our regional understanding.

My main research interest is to study recent (Quaternary) and ancient (Mesozoic) erosional-depositional systems to better understand and quantify how they respond to tectonic and climatic perturbations. The North Atlantic continental margin is one of the areas where this can be investigated at various levels and represents a key study area for further work. This type of analysis required interdisciplinary collaboration and integration of stratigraphy, thermochronology, geodynamics and structural geology. The goal is to make integrated models that can better predict and capture the stratigraphic variability that is present along this and other continental margins.

My daily work place is in Oslo but I visit Bergen frequently. Don’t hesitate to send me an email if you have something you want to discuss! Welcome back Tor 🙂

Geologien på Svalbard

Fikk du med deg NRK TV-serien “Svalbard minutt for minutt“? Det er nå siste dager av programmet på NRK2. “- For en reklame for geologi og klima med mer!!” Her er et lite utdrag fra en av turguidene Stian Aadland som tok sin utdanning fra Sogndal og Universitetet i Tromsø. Det er vel verdt å se hans foredrag om Svalbard her. Klikk deg inn på kl 21.46 varer ca 25 min.

Det er Hurtigrute skipet MS Spitsbergen som reiser (for 177 dager siden) med forskere og TV-team og viser og forteller seerne om den rike naturen og geologien der nord. Vår egen Silje Smith-Johnsen var nå nylig med hurtigrutenskipet MS Roald Amundsen i Antarktis som turguide og forsker. Se uibgeo på Instagram eller tidligere sak i Geoviten for bilder og info.


New publication in AGU100

The Arctic warms much faster than the global average. This amplified response can trigger feedbacks that affect the trajectory of future change. In areas formerly covered by ice, darker open water or rocks reflect less solar heat, enhancing warming. However, freshwater from melting ice may slow ocean circulation, leading to cooling. The climate impact of these mechanisms remain insufficiently understood, restricting efforts to predict future change. To reduce uncertainty, our research uses geological information from the most recent past period when the Arctic was warmer than the present, the Early Holocene, which lasted from 11,700 to 8,200 years ago. We analyzed fats from algae preserved in Svalbard lakes that yield information about past summer temperatures. Our findings show that the Early Holocene was characterized by the coldest and warmest extremes experienced since the last Ice Age. During peak warmth, summer temperatures were 7 °C warmer than today as more solar radiation and warm water reached the Arctic. However, Early Holocene warming was much slower than today. But warming was interrupted when freshwater pulses from melting Ice Sheets lowered temperatures. As we face a warmer Arctic with a melting Greenland Ice Sheet, our findings provide a rare window into the region’s future.

Hi everyone! I recently started as a new PhD candidate at the department of Earth Science. I am a Norwegian-Armenian-American from New Jersey (USA) and I did my undergraduate studies in geology at the University of Delaware.  I came to Bergen in 2017 to do my master’s degree in Quaternary geology and paleoclimate at UiB, which I completed in summer 2019. As part of my MSc, I compiled a glacial striation database for the county of Rogaland, which I used to reconstruct the general ice flow patterns in the Boknafjord region, SW Norway, during the last deglaciation. I also applied LiDAR-based geomorphological mapping, field observations and surface exposure dating using in situ Be-10 to investigate the deglaciation history of the Espedalen region in Forsand, just southeast of Boknafjorden.

For my PhD, I will be focusing on quantitative geomorphology, primarily using surface exposure dating with in situ cosmogenic nuclides to determine ages of glacial landforms. My project is under the purview of the interdisciplinary project SOUTHSPHERE (Past behavior of the Southern Ocean’s atmosphere and cryosphere). Under the supervision of Assoc. Prof. Henriette Linge, I will be using in situ Cl-36, Be-10 and C-14 to date rock samples collected from the sub-Antarctic Kerguelen archipelago during a field expedition in Nov/Dec 2019 in order to develop a chronology of paleoglacier extents and fluctuations on the archipelago. I am looking forward to staying in Bergen and to continue working with everyone here! You can find me in room 3148. Welcome to GEO 🙂
