The four new German Greenpeace / Extreme Ice Survey (EIS) time lapse cameras are installed.

The first was installed 25 June at a 4.6 km wide glacier called Rink Isbrae (71 deg 42.348 min, 51 deg 38.055 min). Rink produces 15 cubic km of is, ranking it number 2 among the most active glaciers in west Greenland. One EIS camera has already been working at Rink, *continuously* since June 2007. Now with two cameras at rink, 3D measurements can be made using “stereo photogrammetry” techniques. Image recording interval at both Rink cameras is 1 h. The Rink Glacier cameras should be revisited ~10 August with an Air Greenland charter if not sooner with the Greenpeace helicopter.

The other three German Greenpeace / Extreme Ice Survey (EIS) cameras were installed 28 June overlooking from 1000 m cliffs on both sides of the 16 km wide Petermann Gletscher (81.5 N latitude). Presently, these cameras are shooting at 1 minute intervals. We plan to re-visit these sites today, weather permitting. Currently we have fog.

Two of the three Petermann Gletscher installations are temporary and will be relocated to one or two candidate glaciers accessible as part of the Extreme Ice Survey (EIS) maintenance tour out of Upernavik or Uummannaq.

*candidate glaciers near Uummannaq:
Kangerdluarssup Sermia (71°14’45.76″N, 51°27’41.36″W)

Kangerdlugssup Sermerssua (71°27’29.79″N, 51°21’32.25″W)

* candidate glaciers near Upernavik (Near Kullorsuaq settlement: Devils thumb):
Alison Glacier (74°37’21.31”N, 56°13’4.99”W)
