Dr. Griet Neukermans from Gent University and @sequoiasci.bsky.social have collaborated for six years on optical sensor development for Particulate Inorganic Carbon detection. So great to see it deployed for the first time!! www.linkedin.com/posts/griet-...

White House FY 2027 Budget Request, planning deep cuts to most agencies (top). This won't help reverse the trend shown at the bottom. Chinas share of global publications has gone from ~0% to ~35% since 1990. With the planned cuts it is hard to see how this trend can be reversed.
Figure showing at the top a bar chart with the US 2026 federal budget and the 2027 proposed budget for NASA, NIH, NSF, DoE, NIST, NOAA, EPA. The bar chart shows cuts for all agencies, from -55% cut at NSF to -13% cut at NIH. The bottom shows 5 curves with the location of authors of scientific papers published in the top 5% of journals since 1980. In 1980 China was at 0%, and at 35% in 2022. In the same period US has decreased from 60% to 25% while EU has been mostly steady around 25-35% and other countries have been mostly stable but at a lower level than the EU.

whoa. first aircraft investigation on another world from #AGU24 Root cause is that the navigation estimation was degraded due to the ground not having enough features for the nav camera to follow So so so cool. Watch here: www.youtube.com/watch?v=p45y...

Very accurate overview of what I have been working on since publishing my first paper in 1998. Thanks to scholargoggler.com and @vittoriobrando.bsky.social
Word cloud showing words that have appeared in research paper titles I have (co)authored. Most common words are sediment, size, particle.

Along the same lines, Daniel Kammen, Victor Vescovo and Jeanne Everett has a new post where they argue that metals from deep sea mining won’t be needed due to changes in battery technology: www.innovationzero.com/zeroin/deep-...

Norway postpones deep sea exploration permits for a while. Sequoia Scientific, Inc.’s LISST-RTSSV (real time size and settling velocity) could help establish environmental baselines AND monitor the environmental impacts of mining operations in near real-time.
