Data of dissolved gas, tritium, stable isotopes, and major ion for Lake Vanda (Wright Valley), Lake Fryxell (Taylor Valley), Lake Hoare (Taylor Valley), and Lake Joyce (Pearce Valley): 2005-2006 Antarctic Season
On 7 January 2010, a SonTek Argonaut-XR 1.5 MHz Acoustic Doppler Current Profiler (ADCP) was fixed at the bottom of the lake ice in the Lake Hoare Limno Hole inside the Polar Haven, looking downward through the water column. Every 10 seconds, the ADCP measured horizontal and vertical current velocities in ten, 30-cm-thick cells between 0.5 and 3.5 m below the lake ice. Over 32.5 hours, horizontal currents in the shallowest cell (0.5 to 0.8 m below lake ice) had a mean speed of 23.8 cm/sec.
