Finishing off 2 days of remote beamtime with Rebecca Metzler here at Colgate University. Lots of great data on the microstructures of past and present marine animals from the Gulf of Mexico, and even a couple of catnaps over the past 48+ hours. Thankful for support for science and for collaborators!

Earth Systems Scares #Halloween #GlobalChange
Ocean acidity has increased by ~30% over pre-Industrial levels due to the uptake of anthropogenic CO2. Pteropods, “sea butterflies,” are planktonic snails that are sensitive to these changes. Scientists have found that their shells are getting thinner & are dissolving, especially at high latitudes.

I am so grateful to all the teachers & students who have participated in the NSF-funded Postcards from the Past project & to my collaborators Tina Miller-Way, JoAnn Mitchell Moody, Nancy Raia, & Linda Hill. Examples of student Postcards are currently on display at the Alabama Aquarium!
Since 2019, Discovery Hall Programs has partnered with Dr. Paul Harnik to develop Postcards from the Past. An interactive activity developed from the field to the classroom to explore the environmental history of the Northern Gulf Coast. A collection is displayed in the Alabama Aquarium.

I love livestreaming the deep sea, especially before class as my undergrad students filter into the room, seeing things they've never seen before. This is possible through the use of ROVs & through federal funding of public-facing science. www.nytimes.com/2025/08/08/w...

It is with a heavy heart that I share the passing of colleague & friend Marilyn Suiter. Marilyn worked steadfastly to support the development of geo colleagues of all career stages, consistently connecting people & highlighting opportunities. She will be greatly missed.

A glimpse into our day at the Diamond Light Source in Chilton, England. Several members of the Paleo Lab are here this week gathering data on the shell microstructures of different marine animals in order to better understand the biotic impacts of anthropogenic climate change.
