Nansen lecture: Understanding polar oceans and their global impact: contributions from CHINARE
Abstract
The polar oceans, including the Southern Ocean and the Arctic Ocean, are key players in global ocean circulation, climate change, as well as marine ecosystems. The year of 2024 marks the 40th anniversary of Chinese National Antarctica and Arctic Research Expedition (CHINARE), which has completed 41 Antarctic and 14 Arctic Ocean expeditions so far, with oceanographic surveys mainly focused on the Prydz Bay, Ross Sea and Amundsen Sea around the Antarctica, and also on the western and central Arctic Ocean. CHINARE has made significant progress in capacity building, ocean observation and scientific research to understand the polar oceans and their global impact, contributing considerably to international programs such as SOOS, PPP, MOSAiC, DAMOCLES and DBO. Here we review some of these progress and contributions, mostly from the perspective of physical oceanography, and briefly outline our future plans and research priorities in the years to come. China is surely in the process of largely enhancing its polar research activities, which will provide support and new opportunities for international collaboration in this important research area, especially with our European colleagues.

Machine learning and the Rise of Data-Driven Models for Weather and Climate
Abstract
With the modern availability of data and computing resources, machine learning is becoming an important tool in solving problems in many domains, from robotics and medicine to weather and climate. In this talk I will attempt to give an accessible introduction to core machine learning concepts, aimed at beginners in the topic. I’ll walk through ideas like supervised, unsupervised and representation learning and share some examples from my own research. I will end by looking at recent developments in large general-purpose foundation models, such as AURORA, and how they’re being applied in climate forecasting and beyond.

Groundwater on ice: hydrogeology and the fate of permafrost carbon in Arctic watersheds
Abstract
The rapid warming of the Arctic where permafrost is prevalent is threatening to release carbon which would accelerate global warming if it reaches the atmosphere. There are many unknowns regarding carbon cycling and budgets in Arctic watersheds. This presentation shows that active layer soil above permafrost functions as a thin but extensive unconfined aquifer made up of mostly of peat. The supra-permafrost aquifer has relatively high porosity and permeability, creating efficient subsurface flow paths above otherwise impermeable permafrost. Observations and modeling reveal that much of the water and carbon going through Imnavait Creek, a headwater river in the North Slope of Alaska, has passed through the supra-permafrost aquifer. Remote sensing showed that supra-permafrost groundwater is prevalent during summer while extensive sampling showed that there is substantial carbon within the supra-permafrost aquifers, as much as those estimated for permafrost. The crucial task of predicting the fate of carbon in Arctic watersheds depends on knowing the subsurface flow properties and processes.

Bjerknes Proposal Writing Workshop 2025 From idea to project: Writing successful project proposals
Registration deadline: 24.04.2025
Link for registration: https://forms.office.com/e/GA2YrAYWjP
Venue: UiB Læringsarena, Nygårdsgaten 5, Bergen
Workshop leaders: Friederike U. Hoffmann, Research coordinator at GFI and EU expert evaluator; Nadine Goris, Researcher and research adviser at NORCE; Catherine Downy, Research adviser at NERSC
Credit point: 1 (ECTS)
Maximum number of participants: 15
Target group is early career scientists (Post Doc, early career researchers, PhD) in climate sciences with little or no experience in proposal writing. The workshop targets both those who already have a concrete project idea and a plan to write a proposal, and those who want to gain general proposal writing and project development skills.
The workshop will enable you to apply for external funding of your own research. You will learn how to develop a research idea into a draft for a successful research project proposal.
Using your own research ideas, you will learn:
how to present a project idea shortly and concisely (pitch presentation)
how to develop and sharpen your research idea
how to plan and structure a draft proposal
how to develop the different components of the draft proposal
how to draft a project budget
where you can apply for funding
The course includes lectures, group work and plenary discussion. During the workshop, the participants will develop the project ideas of 3 participants into ready-to-use draft proposals.
Priorities if the workshop is overbooked: 1. Bjerknes members with project ideas, 2. Bjerknes members without project ideas, 3. Non-Bjerknes members with project ideas. For PhD students: this workshop makes the most sense if you are in the 3rd (or 4th) year of your PhD. PhD students in their 1st or 2nd year will not be prioritized – unless they are working on a proposal, such as for a travel grant, support for events, etc. In this case, please indicate this in your registration.

Bjerknes Hackaton
Hi all!
We're excited to announce that we will be holding the Bjerknes hackathon over two half-days, on May 20th and May 21st!
This is an opportunity to build your skills working with earth systems datasets, and will cover retrieving, analysing and visualising data. The theme of the hackathon will be Air-ice-sea interactions in the Arctic and North Atlantic. In addition to skills development, we expect some really interesting results to emerge from bringing together the diverse expertise of Bjerknes members to tackle this task. In addition to exploring this central focus, we will be providing a crash course on Earth systems data, which should have something for everyone whether you count yourself as a novice or expert data analyst.
The event will run from 9am-12am on May 20th, and 9am-2pm on May 21st. There will be plentiful bolle, coffee and lunch provided for attendees.
If you're interested in attending then register at the link below by next Friday, April 11th :

Bergen at the turning point: Sea Level Change, One Tide at a Time?
How much has the sea around Bergen risen recently? Is it going to keep rising – and how fast? And what does Greenland have to do with it? Sea level isn’t as steady as it might seem. It moves, slowly but surely. The factors driving these changes are complex, and understanding them is key to knowing what’s ahead for Bergen.
In this talk, Konstanze Haubner (University of Bergen, SEAS fellow) and Kristin Richter (NORCE) explore how and why the ocean is slowly reshaping the Norwegian coast. Drawing on research focused on regions like Greenland and Western Norway, they reveal the forces behind sea level change - and what it means for Bergen.
Join us for a talk and a pint, meet colleagues and get an update on the latest ocean research - welcome to all! Please help spread the word in your group.
