High frequency measurements from lake-based "Blue Box" monitoring stations in the McMurdo Dry Valleys, Antarctica from 1994 to present

Summary

Abstract: 

As part of the McMurdo Dry Valleys Long Term Ecological Research program, continuous stage (lake level), ice surface ablation, surface PAR, and underwater PAR are collected at various lakes throughout the McMurdo Dry Valleys of Antarctica. This package contains data measured at 20 minute intervals for Lake Fryxell, Lake Hoare, East Lake Bonney, and West Lake Bonney in Taylor Valley as well as Lake Miers in Miers Valley. MCM sometimes refers to these measurements as "blue box" data because the instrumentation used to be housed in a blue box.

Date Range: 

December 5, 1994 to December 11, 2018
