The Wormherders take soil samples from the SLIME experiment site on the northern shore of Lake Bonney. On their left is the dive hut used by other LTER scientists who dove under the ice to collect lake sediment samples. On their right is a sensor station that records information from buried soil moisture sensors on the lakeshore. Natasha Griffin (CC BY 4.0)

The ‘Wormherders’ make their way across the permanent ice cover over Lake Bonney to their research site.
