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.

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!
