Earthquakes have never been easy to study in the oceans, but documenting their processes is important as scientists continue to conquer the data-poor seas. Ocean-bottom seismometers are relatively commonly used to gauge quakes undersea, and moored hydrophone systems pick up the odd earthquake as well. But those tools are expensive and difficult to deploy. Enter the Son-O-Mermaid, a platform developed over the course of decades to make things simpler and much less costly.
We pay far too little attention the northern and southern glaciers of the Canadian Arctic archipelago. If you do an entire inventory of all the glaciers, they actually are changing more than Greenland and Antarctica at the moment, or have been,” says Princeton geoscientist Christopher Harig, who conducted the new study in Geophysical Research Letters along with Princeton’s Frederik Simons.
In the freshman seminar, "Earth's Environments and Ancient Civilizations," students study how to use global positioning systems (GPS), archaeological and geological data, geophysical technology, and computer programs to seek and examine the buried remnants of lost civilizations. The course included a trip to Cyprus, where students collected data for final presentations about how ancient civilizations altered the landscape and changed the environment — and vice versa.
