Diagnostic pill for glaciers

Glaciologists are getting with the times and using wireless sensors to study glacier's behavior. The devices, which look like elephant-sized pills, are placed at the bottom of glaciers so that they move with the ice and wirelessly relay temperature, pressure, speed and data on the makeup of the lower glacial layers. This data is relayed to the researchers via base stations on top of the glaciers and uploaded to the internet. Just for kicks the data can also be relayed via SMS text messaging. We're wondering where they got their gear, as we've been know to have trouble getting our WiFi signal to reach across our apartment. Best of all the sensors for an ad-hoc network among themselves, which allows a much higher level of sensitivity. Of course, all of this data is going to tell us that the end is near anyway, that the glaciers will melt and we'll all be stuck in a bad Kevin Costner movie. Just you wait.
