This blog Site. Posted by Mauri Pelto. Porcupine Glacier, British Columbia in a July 4, Sentinel image illustrating the retreat from and new iceberg breakup B. Red arrow is terminus location and yellow arrows terminus locations of both branches. Porcupine Glacier is a 20 km long outlet glacier of an icefield in the Hoodoo Mountains of Northern British Columbia that terminates in an expanding proglacial lake.

During the glacier had an unusually large 1. NASA generated better imagery to illustrate this observation. The southern branch of the glacier has a tongue poised to breakup at that time B. Here we examine the change in terminus position and iceberg deterioration from using Landsat and Sentinel images. In the glacier had retreated 3. In there are two tongues of the glacier vulnerable to calving at Point A and B.

Terminus sentinel Iceberg A has calved generating an immediate retreat of 1. The iceberg is plugging smaller icebergs from moving down the lake. In August the iceberg because of its size has still drifted little and at 0. This has enabled smaller icebergs to move past the iceberg down the lake. In July of the iceberg has diminished further to 0.

The glacier tongue at Point B narrowed considerably from to and is poised to separate. The narrowness and potentially shallower terminus sentinel of this inlet may make it difficult for a single iceberg to emerge from the collapse of this glacier tongue. Iceberg B calved in the summer of and by July of is in four main pieces. The retreat of the main terminus from is m and for the southern branch it has been m. Porcupine Glacier in Landsat images from and Porcupine Glacier in Landsat images from and and Sentinel Image.

Iceberg A and Ice tongue B are indicated on each. The haziness in is forest fire smoke. The yellow arrows mark the terminus location.
