Exciting to join the first international meeting in Germany after two years of the pandemic. In August 2022, I was invited by Prof. Bernd Jähne to give a talk at the Gas exchange workshop (Cross-linking lab and field measurements and numerical modelling to identify and quantify the mechanisms of air-sea gas transfer) held at Heidelberg University. This is the first time for me to join an academic meeting outside of UK during my PhD.
Heidelberg is a very beautiful and quiet city. I stayed in there for three days. I enjoyed jogging along the Neckar river in the morning. Heidelberg university is a world famous university. I walked in the campus before the workshop and was impressed by their buildings. The style of the building is like a square which gives me a feeling of steady, preciseness and rationality.
I was the only one working in the UK who joined the Heidelberg workshop because the UK marine society was celebrating the Challenger 150 conference at that time. I gave a ~30-min talk and listened to many interesting presentations. At the end of the first day, the host led us to visit their splendid annular wave tank. The Heidelberg group has one of the most historical wave tanks and now they developed a new wave tank named Aeolotron, which is much bigger than the old one.
I had many discussions with Bern Jähne and Kerstin Krall (Heidelberg University), Christa Marandino from the GEOMAR Institute, Alex Babanin from the University of Melbourne. The estimate of the gas exchange rate relies on the parameterization with wind speed, but the ocean waves/bubbles might play an important role in the air-sea gas transfer. The current lab. results, field measurements and theoretical work show discrepancies on the bubble-mediated gas transfer, which is a big gap to fill for the air-sea gas exchange community.
I am very grateful that I had this chance to contribute to this workshop and to meet so many excellent senior scientists with amazing research discussions. I got many ideas for my further study. More importantly, I established the collaboration with Bernd and Christa, which will benefit for my career.

Marine Data Management, Governance and the MEDIN toolset
The Marine Environmental Data and Information Network (MEDIN) and OceanWise are delighted to invite you to attend our popular free online training workshop: ‘Marine Data Management, Governance and the MEDIN toolset’ on the 19th – 23rd of May 2025.
Workshop on the contribution of UK Arctic Ocean science to the International Polar Year 32/33
12:00 11th June – 16:00 12th June 2025: NOC Southampton (In-person with online option): Registration deadline 16th May
REGISTER HERE
Pre-meeting questionnaire (open to all)
The purpose of this workshop is for the UK Ocean Science community to discuss and then draft a prospectus document outlining the priority Arctic research questions the community would like to address during the run up to, throughout and beyond the International Polar Year 32/33. Additionally, to identify what unique strengths and technologies the UK has to help fill these knowledge gaps.
The second day of the workshop will be dedicated to writing groups, one for each of the priority research questions identified - from both the pre-meeting questionnaire (HERE) and day one discussion. By the end of the meeting, each group will have produced draft text and sourced supporting figures for the prospectus.
Post meeting, the draft will be opened for comments and suggestions from everyone, regardless of whether they were able to attend the workshop or not. It will then be shared with UK funders (UKRI, FCDO, DSIT, ARIA) and potential international programmes with whom we would like to collaborate (e.g. Arctic 2050, Norway). It will form a basis from which wider integration with terrestrial, atmospheric and cryosphere communities can be built, e.g. at the UK Arctic Science Meeting in September in Northumbria.
To ensure balanced community and ECR representation, and to ensure that the size of the writing groups is efficient and effective, if the number of registrations from individual institutes becomes overwhelming, we may contact individuals or teams and ask that each institute selects a smaller number of individuals to attend in-person. Please wait for confirmation of in-person attendance before finalising travel arrangements.
The workshop will be open to hybrid attendance and contributions on both days.
Challenger Society Council Position Vacancy
The Challenger Society for Marine Science (CSMS) are pleased to announce an exciting opportunity to support the next generation of ocean scientists and innovators.
