PMEL scientists from the Earth-Ocean Interactions Program will be on board the E/V Nautilus, which is operated by the Ocean Exploration Trust (OET), during June 1-20. This expedition will explore and characterize habitats and methane seeps along the Cascadia continental margin between northern Washington and Cape Mendocino. Broadband video of the seafloor during the dives from OET remotely operated vehicle Hercules will be broadcast in realtime over the internet. Scientists ashore representing a broad range of expertise will also participate via a realtime link to the ship during the dives.

The scientists... more
