What did the surface of Earth look like more than three billion years ago? What kinds of microbes lived there and when did they start producing oxygen? And what was the temperature and composition of the ancient oceans and atmosphere? Big questions like these is what drew a group of 41 scientists to sunny Berlin last week, including our Associate professor Desiree Roerdink.
Underneath the ocean floor, thrives a vast biosphere which activity profoundly impacting our global environment; from the air that we breathe, to the balance of the global carbon budget. The functioning of this biosphere is what the new director at the Centre for Deep Sea Research at UiB, Steffen Leth Jørgensen, seeks to understand.
Scientists taking part in the 2023 GoNorth expedition have discovered a new hydrothermal field – an area with sea floor hot springs – in the Lena Trough, part of a mid-ocean ridge between Svalbard and Greenland.
Early August, the GONORTH cruise organised by several Norwegian institutions came to an end. On its last ROV dive, a new hydrothermal vent field, named Ultima Thule, was discovered on the Lucky Ridge!
Håvard Stubseid and his colleagues just published a new article in Nature communication.
On Monday 19. June 2023 Åse Hestnes defended her PhD thesis: The post-Caledonian tectono-thermal evolution of Western Norway
On Friday 16. June 2023 Vilde Dimmen defended her PhD thesis "Geologic controls on fluid flow and seismic imaging of faults in carbonate rocks - Insights from quantitative outcrop analysis and reflection seismic modelling"
The ongoing GONORTH cruise is pushing the limits of deep sea exploration in the north.
Here are the new institute council representatives for Gr. B and Gr. D for the period 01.08.2023 - 31.07.2024!
Last week, the Department of Earth Science hosted a successful workshop on "Greenland ice sheet stability: lessons from the past". The workshop attracted 70 international participants from various disciplines and institutions. The main goal of the workshop was to foster interdisciplinary collaboration and exchange of ideas on the past, present and future of the Greenland ice sheet.
The second week in April the DeepReservoir team was in the
Ravenglass Estuary just north of Liverpool, with project partners from AkerBP,
Equinor and the Universities of Oslo, Delft and Liverpool.
17.-20. April the field part of GEOV102 was held in fantastic weather at Herdla and at Ulven. Eager students have worked independently in the field and have logged sediment profiles, studied beach deposits, collected georadar data, taken sediment cores and carried out structural geological mapping at Ulven.
Nyberg et al. (2023) introduce the Global Channel Belt (GCB) model in a new publication published in Nature Communications. The authors use advances in machine learning to identify patterns that define landforms characterizing the extent of river channel belts, including the river channel and their associated levees, bars, splays, and overbank features.
Bachelor student Andrea, is in her last semester of her bachelor's degree in geology at department of Earth Science, UiB. She says: "I'm one of the two lucky ones who got an internship at Brønnøy Kalk".
Francesca vulcano and her coworkers have been awarded the 2022 best article award from FEMS microbiology ecology. The article investigates the evolution and adaptation to different environments of anaerobic methane oxidizing Archaea.
