Interpreting Arctic Satellite Images And Data #2 - Animations

Now that NASA's MODIS rapid response system is back online I am able to present some animations which I hope you will find interesting.

This article is a continuation of Interpreting Arctic Satellite Images And Data.

Interpreting Arctic Satellite Images And Data


Science writers and media reporters owe a duty of care to their readers: a duty to present facts undistorted by personal opinion or agenda.
That duty of care extends not just to what is written, but to what is portrayed in graphs and images.

A graphic produced for a specific science-oriented context can be as misleading if taken out of context as any cherry-picked data or quoted words.

Sermeq Kujalleq - Jakobshavn Isbrae Retreat

The Jakobshavn Isbrae, or Jakobshavn glacier, now becoming known by its local name - Sermeq Kujalleq - has been observed retreating since about 1851.


Near the small town of Ilulissat, formerly Jakobshavn, Sermeq Kujalleq is the Northern hemisphere's largest glacier with an outlet to the sea.  It drains about 6.5% of Greenland's ice sheet. The ice stream's contribution to sea level rise is about 0.06 millimeters - about 0.002 inches - per year, roughly 4% of the 20th century rate of sea level increase.
