Video: What's growing at the bottom of Crater Lake?

Scientists are setting out this month to answer some questions concerning the large growth of moss at the bottom of Crater Lake in Oregon. CNET News.com's Vincent Tremblay reports that a remotely operated vehicle system will be used to gather video footage, as well as test samples, to determine how this natural community fits into the lake's ecosystem. The research is being carried out by representatives of Oregon State University, the National Park Service, USGS and Southern Oregon University.
