Lake Vanda thermocline temperature time series

Summary

Abstract:

This data set includes the deployment of anchored thermistors Lake Vanda, Wright Valley, as part of an Antarctica New Zealand project. Thermistors were positioned at the sediment-water interface and 10 cm above the lake bottom within the thermocline at 24 m depth.

This dataset is funded through the New Zealand Foundation for Research, Science and Technology grant # CO1X0306 and the NASA grant NNX13AI60G, with USAP event G-063. This project is not funded through the MCM LTER program. MCM LTER hosts this synergistic project.

Methodology

Methods:

The instrumentation deployed in this study were deployed by SCUBA divers at one site in Lake Vanda (77º 31.6´S,161º 36.3´ E). Thermistors were each RBR Ruskin Solo T loggers. One thermistor was set on the lake bottom at the sediment-water interface (Temp 1), followed by one thermistor suspended 10 cm above the lake bottom (Temp 2). These deployment locations were chosen to identify the effects of solar heating or standing waves in Lake Vanda.

Thermistors were near other sites of diving activity, and divers were in the vicinity of the installation during the following periods: 12/08/2013 14:46-15:13; 12/09/2013 12:06-12:33; 12/10/2013 09:22-09:35; 12/11/2013 10:23-10:39; 12/12/2013 10:08-10:34; 12/12/2013 10:51-11:17; 12/13/2013 10:20-10:32; 12/15/2013 09:47-10:16; 12/15/2013 15:36-16:07; 12/15/2013 16:26-16:43; 12/16/2013 13:33-13:56; 12/17/2013 11:15-11:53; 12/17/2013 12:09-12:39; 12/18/2013 09:57-10:26; 12/18/2013 10:52-11:13; 12/20/2013 10:48-11:24; 12/20/2013 11:41-11:53; 12/20/2013 17:01-17:32; 12/20/2013 17:41-17:59; 12/21/2013 11:59-12:23; 12/21/2013 12:30-12:55. Measurements from these time periods should accordingly be inspected for disruption prior to analysis.
