Thermistor array for under ice

Building a thermistor array to leave under the ice for the winter to look at cold stratification of the lake over the winter. Using an adafruit datalogger and 10K thermistors from adadfruit, I have a short string of three thermistors which will be placed in the lake next week hopefully.
String is complete for testing - here are the values being logged to the SD card for 3 thermistors at three depths (currently sitting in the workshop so values are in the 20s).

Graphic user interface for science

User interfaces for scientific instrumentation typically use a Windows/Visual BASIC format and look frankly a little boring.
But there are attempts at different interfaces using libraries in processing such as the G4P library.
There is also some interesting work in the controlP5 library
