AGU 2015 – Day 3 – Tiredness and Structure-from-Motion

It’s now the third day of the AGU 2015 and the tiredness starts to kick in, making the morning poster session a bit difficult and slow until the coffee break at 10:00. However after the caffeine reached my brain, my day started and I saw some pretty good things. Most of the day was dedicated to snow processes and remote sensing of the cryosphere so obviously there was a lot of Structure-from-Motion (SfM) studies.

One poster was combining the 2 subjects of the day: Phillip Harder (University of Saskatchewan) was displaying a study on how to use UAV, SfM and modelling to better understand snow depletion.

In the talk session of the afternoon, the 3 presentations which I think stranded out were:

  • Jessica Cherry talked about the cost of SfM vs traditional photogrammetry and how to take them into account before choosing a remote sensing solution.
  • Matt Nolan presented his work on measuring the elevation of some Alaskan mountains using SfM (
  • Gabriel Wolken showed that is possible to measure snow depth with a very good accuracy on a vast domain using SfM.

I concluded my day with a drink at “the Thirsty Bear” bar with David Rounce, his supervisor Prof. McKinney and some other people that I can’t remember the name (sorry guys, too many people in this conference)!

AGU 2015 – Day 2 – Monitoring glaciers

Day 2 of AGU was general cryosphere information day for me with talks sessions on glaciers monitoring and remote sensing. Obviously there was a lot attention given to Greenland but some good talk too about mountain glaciers especially in the Himalayas.

One poster made my day: Orie Sasaki (Tokyo Institute of Technology) poster about automated worldwide extraction of debris cover on glaciers. The results are not yet published but when it will be it will be very good to access the importance of debris-covered glaciers in every mountain ranges and not only in Alaska and Nepal.

Fun fact: Google is actively campaigning in the Exhibitor Hall for the use of the the Google Earth Engine. It looks good, probably just need a bit advertisement.

Three talks kept my attention:

  • Mauro Fisher on the use of LiDAR for monitoring glaciers with only one station per glacier.
  • Mark Fahnestock on feature tracking to evaluate surging glaciers velocity in Alaska
  • Luca Foresta on geodetic mass balance in Iceland using a new method on CryoSat altimetric data.

All these talks are very promising on technical level and give good hopes for monitoring glaciers in the face of climate change.

The end of day was marked by the Cryosphere Focus group reception in the Marriott Hotel: pretty good place to network… And NETWORK! I didn’t find a job for next year but still pretty good 😀
