On Monday I'll start a new job (a detail for six months) and I'll be working on communications about our agency's work on the BP Gulf of Mexico oil spill.
The scope of this disaster is hard for me to comprehend. I found a widget from the Public Broadcasting System that shows how much oil has leaked since the incident began April 20. You can adjust the rate based on the various estimates available.
If It Was My Home uses Google Maps to show you the surface area of the spill superimposed on your part of the world. This is oddly effective, since you have probably visited places at different distances from your home and have a personal grasp of how far the spill reaches.
