We had a look around three glaciers on our first day in Iceland in 2017 – to check for access. Here we are on the massive sandur of Breiðamerkurjökull.
ublox m8 tests
Local tests – mainly to debug the python code – of the ublox M8P have produced fast fixes today.
First test of Swift Navigation Piksi Multi dGPS
These new dGPS units seem to be accurate to around 2cm as shown in our test. This is for a close baseline (and at the moment doesn’t use GLONASS).
Iceberg Tracker moves on but seems in trouble
We have been checking the iceberg tracker temperature as one way of telling if it is in the sea is a flatter daily variation in temperatures. Here you can see it did regularly read sub-zero at midnight then warmer an noon. Recently however it is showing mainly positive temperatures.
After spending weeks among the small islands in the centre of this map – it has moved south until reaching land again. This dramatic movement may be because the iceberg has broken up.

This is the scenic video of Lucas di Grassi driving a Formula E car on a Greenland glacier.
Together with the sustainability team of Formula E we were able to put a GPS tracker on an emerging Iceberg in order to see its movement in great detail. The box contains a tracker which sends the GPS location and temperature twice per day via satellite messages.

Iceberg tracker almost stationary in some islands
Our GPS data is showing us that the iceberg we are tracking has been drawn into some islands and has stopped moving significantly. The MODIS image data from Nasa was very clear on this day and it is possible to see ice between the islands:
Iceberg tracker
This is a GPS tracker we quickly built as a test of tracking icebergs – it uses Satellite (Iridium) short text messages to send its location to us every 12hrs. Inside is a large lithium battery pack. The photo below shows a water test in the sink – just in case it ends up in the sea. We used a unit from YB Tracking. More info later!
