You may have noticed a surge in jellyfish lately. While populations appear to be rising, their gelatinous bodies and drifting nature make them notoriously difficult to track. That’s where science steps in. A new instrument on the UTMSI research pier can record smaller stages of jellyfish. 📷 Herzka

Being a scientist has its benefits, especially when it’s 100F+ in Texas. The Nielsen Lab and USGS colleagues are enjoying cooler weather while sampling at Grewingk Glacier in Alaska to learn about the sources, export, fate, and bioavailability of #mercury released by rapidly retreating glaciers.
