Fog water sampling at the UCSC Coastal Campus

Picture by Anja Ulfeldt
A full bottle of fog water was collected in one night during May of 2025. This water can be viewed through a microscope at a Seymour Center exhibit on fog. So far, we have collected 4 fog water samples and have analyzed the biological content of the water. We plan to present the results at the AGU Fall Meeting in New Orleans.

Art + Fog Collective works on “Harvesting Water from the Sky”

Art Professor Jennifer Parker and Artist in Residence Anja Ulfeldt have teamed up with UCSC interns and Peter Weiss to create an augmented reality project highlighting the importance and interconnectedness of fog.

Art+Fog Collective: Harvesting Water from the Sky

Click on the tab Art + Fog to find out more about this project. This work is being showcased at the UCSC Coastal Campus Seymour Center, where children and adults can observe a fog tank, an actual garden bed fog collector, and be able to look at fog water under a microscope.

Paper published on mercury emissions from mines revealed using lichens.

Exciting news! A paper was published this year on mercury in lichen measurements in and around the New Almaden Quicksilver Mining District. The work was done in collaboration with Peggy O’Day at UC Merced and her team who was able to analyze the lichen for chemical forms of mercury using X-Ray spectroscopy. The work was funded by the Eppley Foundation and the Santa Clara Water District. To find out more about this work, click on the Environmental Toxicology of Mercury tab. The lichen photo was taken by Belle Zheng, one of the student coauthors on the paper. Brittney Straw was another student coauthor and she did a lot of the lichen sampling around the Almaden and Guadalupe Reservoirs.
