Probe Data is complex to analyse and interpret

This is a sample of data from a 2004 probe (8) in Briksdalsbreen

The external pressure is shown as metres of water depth equivalent. and the x-tilt represents movement/rotation. Notice the changes brought by spring. Resistance shows if the sediment (till) is "dry" (when high) or "wet".

sample 2008 iceland probe data

This sensor data is from Iceland 2008 (Temp is C others are relative). It shows the first data from the light reflectance sensor (yellow) which is reducing as the ice closes around the probe. It also shows interesting strain oscillations.

graph showing probe 21 data in spring

This sample of data from probe21 in iceland shows water pressures (converted to metres water equiv) increasing in Feb. along with electrical conductivity (right Y axis microSiemens) - from melting - even though the glacier surface was still snow covered.
