Working with marine carbonate-system observations has taught me how much effort lies behind every row of an oceanographic dataset: long hours at sea, careful sampling, laboratory analyses, calibration and quality control. A single bottle of seawater may represent only one place, one depth and one moment, but when many such samples are brought together, they can reveal how the ocean is changing. On ...[Read More]
The EGU Ocean Sciences division blog is looking for new volunteer editors. So far, the team consists of two early career scientists, Jacqueline and Maurie — both working in ocean biogeochemistry — and we would love to grow. As an editor, you will keep an eye out for interesting new articles and datasets to write about, write short blog posts about ocean related news, and approach other scientists ...[Read More]
On Monday 4 May, Tillys Petit delivered the OS Division Outstanding Early Career Scientist Award Lecture at EGU 2026 in Vienna. We chatted with her about the hidden engines driving the Atlantic Meridional Overturning Circulation, and why that matters for the future of our climate. Spoiler: it’s not just about the Labrador Sea! 🌊 Can you share your career journey with us? Did you always dream ...[Read More]
Here is a great resource for anyone working on ocean carbon: Jiang et al. (2026) compiled a comprehensive synthesis of data products for ocean carbonate chemistry — all in one place for you! The paper provides a comprehensive synthesis of 68 existing ocean carbonate chemistry data products and data product sets, including: 🛳️ Cruise-based Compilations 📈 Time-series Datasets 🗂️ Gap-filled Observati ...[Read More]
Chlorophyll-a (chl-a), as the dominant photosynthetic pigment within phytoplankton, provides an indication of the phytoplankton biomass and are essential for understanding global and regional changes in primary production in the oceans. Multiple ocean colour satellites have unlocked routine synoptical scale observations of chl-a which now extends from 1997 to the present day. Differing numbers of ...[Read More]
Meet the new Early Career Scientist (ECS) Representative for the Ocean Sciences (OS) division: Arianna Olivelli! In this role, she is dedicated to connecting, supporting, and advocating for early career ocean researchers across Europe and beyond. We sat down with Arianna to hear about her journey, her vision for the OS ECS community, and how she is empowering the next generation of ocean scientist ...[Read More]
As climate change continues to reshape our oceans, science communication remains vital to the research and development of mitigation strategies. For scientists and engineers working on climate solutions, much of the conversation happens through technical papers, conference presentations, and policy memos. But invested communities outside these circles may have little access and limited time to con ...[Read More]
Jens Terhaar received the 2025 Division Outstanding Early Career Scientist Award for his research on the ocean carbon cycle and its effects on climate. We spoke with him about his career path and the work that led to this award. Since completing his PhD in 2019, Jens has made a name for himself with many publications and outreach efforts. His work is about the ocean carbon sink, ocean biogeochemic ...[Read More]
Tatiana Ilyina received the Fridtjof Nansen Medal from the European Geosciences Union (EGU) for her outstanding research in oceanography. We spoke with her about her career path and the work that led to this award. Here’s what you should know about her. Tatiana Ilyina studied Meteorology/Oceanography during her PhD at the University of Hamburg, continued as a postdoc at the University of Haw ...[Read More]
