My next post about the Geology of the National Parks Through Pictures is from a trip to Ohio shortly after we moved to New York for a memorial service for my dear friend Dale.

As we left EGU26 behind with record participation, it was amazing to see increased interest in science-policy sessions from the scientific community. Thanks to all panellists who contributed to the stimulating discussions, and to all participants for igniting them!

This interview is part of an ongoing series exploring the evolving role of interdisciplinarity across the geosciences. As environmental challenges grow more complex, addressing them requires not only disciplinary expertise but also meaningful collaboration and innovation across fields, methodologies, and communities. In each conversation, I ask Division Presidents to reflect on how cross-divisional work is currently practiced, where it falls short, and what more transformative forms of collaboration could look like. Through this series, I aim to surface both practical pathways and significant tensions in interdisciplinary work to highlight why it matters for research, policy, and the broader societal relevance of the geosciences.

I find much to like about house wrens, including their scientific name: Troglodytes aedon.  It's very appropriate for this vigorous singer and cavity nester. Troglodyte is from the Greek for "hole or cave dweller," while aedon, also Greek in ...

Geodesy is fundamental to understanding our dynamic planet. From monitoring sea-level rise and glacier melt to maintaining precise terrestrial reference frames for GNSS and Earth observation, geodesy provides the scientific backbone for many disciplines represented within the EGU and beyond. Despite its importance, geodesy often remains invisible outside the scientific community. Even within geosciences, many people use geodetic products daily without fully realizing the complex infrastructure and science behind them.

The first time I stood on sea ice, I could not tell which direction the coast was. A community member named Bryan could. That gap in situational awareness, between what a trained remote sensing scientist could read from the landscape and what a local hunter understood instinctively, turned out to mirror almost exactly the gap in our satellite data: ICESat-2 produces reliable freeboard across the central Arctic but goes systematically blind within 25 km of every coastline. This post traces that coastal data gap from its algorithmic roots through its ecological and human consequences, and asks what it would mean to build satellite products that close it on the terms of the communities who need them most.

THE REALITY BEHIND FLASHY JOB TITLES I recently spoke with someone who works for a large international operator. To me, as a representative of a very small company, the job titles these people have always sounded very impressive. Exploration manager, this or that, it all suggests major responsibility and momentum. But when I bluntly asked...
