- New information on moss distribution, biomass, and history in the lake is one of the most significant development in the ecology of Crater Lake in 40 years.
- the moss is a type of bryophyte (Drepanocladus sp. and Fontinalis sp.)
- the moss is most common around Wizard Island, but can be found around the margins of the entire lake
- the moss grows at 25-140 meters
- field studies used remotely-operated vehicles (ROV), multi-beam sonar, side-scan sonar, and sonar back-scatter analyses to map the moss locations
- dead moss layers, underlying the live moss, have been dated at several thousand years old
