Here are some photos from our American Geophysical Union (AGU) conference and visit to National Geographic in Washington.
We also participated in the ESSI organisation and EOS.
Here is a quick snapshot of some data from the new Fjalls site:
It is already approaching 2m distance from its original location – also the jitter on the positions is very small.
This is temperature from Rover4’s Peli case, which is the heighest on Breida and is showing good variations (X axis starts in August).
here is a page on our 2018 Iceland fieldwork
We have been awarded a National Geographic Explorer grant entitled “A tale of two glaciers: using web connected RTK GPS, drones and remote sensing to monitor rapid glacier retreat of two contrasting Icelandic glaciers”. This will be a two year project to examine the rapid retreat of two icelandic glaciers, using the innovative web connected dGPS system.
“At around 5 AM Pacific Time (1 PM GMT) today (March 7th) the GPS satellites started transmitting inconsistent health information causing Swift Navigation receivers to exclude measurements from any satellites supporting the L2C signal. This has resulted in degraded or unavailable position information and decreased ability to achieve an RTK Fixed solution.”
We kept an eye on the data coming in – as it is not easy to go to Iceland and update the firmware..
There is a nice write-up from Formula E on Ice drive: a lasting legacy:
Today we set up two dGPS units to measure the speed of some of Fjallsjökull glacier. We chose an area of ice which is clearly moving forward towards the lake.
The photo above shows a “quadpod” supporting the GPS units – which are an adaptation of those made by Matthew Roberts of the Icelandic met-office. The idea is to be strong enough to cope with winter and cast few shadows (which cause ice to grow). The system is currently measuring its position every 3hrs to an accuracy of about 2cm – using signals from the base station to help it.
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).
