Lakes Blue Box data (Continuous stage (lake level), ablation, surface PAR, underwater PAR)

Summary

Abstract: 

Continuous stage (lake level), ice surface ablation, surface PAR and underwater PAR are measured at 20 minute increments for Lake Fryxell, Lake Hoare, East Lake Bonney and West Lake Bonney in Taylor Valley as part of the McMurdo Dry Valleys LTER project. MCM sometimes refers to these measurements as "blue box" data because the instrumentation used to be housed in a blue box.
