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]

Can the Ocean Explain Why Climate Models Struggle with the Indian Monsoon?

Sankar Prasad Lahiri July 9, 2026

Figure 1 Schematic illustration of the Indian Summer Monsoon circulation. During boreal summer, southwesterly winds (blue arrows) originating near the Mascarene High in the southern Indian Ocean travel across the Arabian Sea and Bay of Bengal toward the Indian subcontinent. Along their path, the winds acquire moisture from the ocean before producing widespread rainfall over South Asia. Image created with the assistance of ChatGPT-5.

Few climate phenomena affect as many people as the Indian Summer Monsoon (ISM). Between June and September, it delivers most of the annual rainfall over the Indian subcontinent, supporting agriculture, water resources, and livelihoods for more than a billion people. Yet predicting how the monsoon will respond to climate change remains a major scientific challenge because it is shaped by complex in ...[Read More]

Book Review: The Swarm by Frank Schätzing

Jacqueline Behncke June 16, 2026

So far, our reading adventures have kept us close to reality with Blue Machine by Helen Czerski and Below the Edge of Darkness by Edith Widder. Now, we are turning to a work of fiction. The author did plenty of research and spoke with scientists, who even appear as characters in the book, resulting in the science-fiction eco-thriller The Swarm. For centuries, humans have treated the ocean as a res ...[Read More]

Join the EGU Ocean Sciences blog team 🌊

Jacqueline Behncke and Maurie Keppens June 2, 2026

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]
