Breiðamerkurjökull speeds up in spring 2019

the distance moved by one of the Breiðamerkurjökull nodes shows us the glacier has started moving again – at a rate comparable to the previous autumn. Its also great that this prototype node has sent data so continuously – right through the winter!

Fjalls altitude rise

Fjalls tracker jumped in altitude in March! it is part if its general trend to rise – probably due to the presence of the large ice-cored moraine by the side of the glacier.

AGU 2018

Here are some photos from our American Geophysical Union (AGU) conference and visit to National Geographic in Washington.

Our poster about “The Glacier in Winter” – showing the range of processes that occur throughout the winter.
Our poster about the soft-bedded hydrology.
A view across part of the AGU poster hall in Washington. The yellow flags are where the Earth and Space Science Informatics posters are!
Visiting the National Geographic headquarters in Washington – where we met other Explorers and heard excellent short-talks about their research.
The talks in our 2018 ESSI session on “New and Emerging Technologies for Earth and Space Science” chaired with colleagues from NASA.

We also participated in the ESSI organisation and EOS.

3D model fly through of Fjallsjokull

We captured thousands of images using a quadcopter, Survey 3 camera and then created the model with Agisoft Photoscan. Calibration targets on the ground geo-referenced the model. This fly-through is a screen capture from their viewer. The model-making process took around five days on a quad-core 4.4GHz PC. Models will be produced each year to monitor changes but they also help visualise moraine formation. The images captured were about 7mm/pixel resolution.

Good data coming in already from all nodes!

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).

Sats used in the fixes

This long term plot for Breida’ show the number of satellites used for each fix. It shows the normal variation due to their paths in the sky. It is quite consistent throughout the winter.
