Ocean acidity has increased by ~30% over pre-Industrial levels due to the uptake of anthropogenic CO2. Pteropods, “sea butterflies,” are planktonic snails that are sensitive to these changes. Scientists have found that their shells are getting thinner & are dissolving, especially at high latitudes.

Looking for a postdoc for 2026? Interested in the interfaces between sedimentology and geochemistry? Biology and the seafloor? Climate change at sea? Come join my new group! I'm looking for candidates to apply with us for MSC fellowships on a range of topics. 🧪⚒️🌊
Accepting applicants for Marie Sklodowska Curie fellowships 
Looking for your next (or first) postdoc? Come apply with us for a Marie Sklodowska Curie fellowship. Our work ranges from marine chemistry, environmental reconstruction, climate change in the marine environment, diagenesis, sediment-water interactions and more. 
We are looking for excellent candidates — geologists, sedimentologist, geochemists, modellers, computational geoscientists and others in the earth and marine sciences space — interested in working on (but not limited to) the following research themes:
- Sediment-water interactions.
- Low temperature carbonate mineral reactions/interactions. 
- Seafloor fluxes. 
- Role of waves and storms in sediment distribution. 
- Abiotic control factors on benthic communities. 
- Long term fidelity of environmental signals. 
An ideal candidate should be interested in working in a highly multi-disciplinary environment, eager to share their knowledge and learn. 

Are you interested?
Please send a synopsis of the project you wish to work on, and a copy of your CV (including list of publications), to obialik@ocean.org.il by June 30th 2025 the latest. The deadline for proposal submission is mid-September 2025.
