I am a climate scientist, focused on paleoclimate, sea level change and the evolution of Quaternary glaciations.
I reconstruct ice sheets using glacial isostatic adjustment and ice sheet modelling. In Japan but have been all over the place. 🇨🇦🇯🇵🇦🇺🇩🇪🇸🇪

Hello Bluesky folks! I am interested in meeting people working on climate, sea level and ice sheets, especially with reference to the past. Please visit my website for a larger bio! raisedbeaches.net/about/

We’ve hit a century! 100m of core! Our night-shift crew took us past this milestone – we’re now more than halfway towards our target. Reaching this point is testimony to the skill and hard work of our drillers, who are clocking up long runs and cores of up to 3.1m 👉https://bit.ly/4aHvt5e

Large glacial erratic along a gravel road in Iowa, photo by Jim Knox, 1967. I think this is one of the "Giant Boulders of the Iowan Drift" (titled of an obscure older article). This is on the Iowan Erosion Surface, an area of Middle to Early Pleistocene glaciation that was the subject of much debate

There is some discourse right now on how not everything is digitized and cannot be replaced with generative AI summaries. Another point is that sometimes the data is scattered around, and you need to put it together in a standardized way. This requires expertise. I am doing this with sea level data.
