Weekly CTD profile measurements of conductivity, specific conductance, temperature, depth, density, and salinity from Lake Hoare, McMurdo Dry Valleys, Antarctica during the 2012-2013 austral summer
As part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project, we investigated relationships between wind conditions and barotropic seiches within Lake Hoare, located in Taylor Valley, Antarctica, during the 2012-2013 austral summer. Temporal changes in the water column were measur...
