Sounds from the Southern Ocean is a joint project between NOAA-Pacific Marine Environmental Laboratory, Oregon State University, and the Korea Polar Research Institute whose goal is to study the dynamic tectonic and volcanic environment of the Bransfield Strait and Drake Passage. We completed two main tasks this year: the recovery and redeployment of a hydrophone array and an ROV survey of the

Bill reports that the team arrived safely in Chile. He's flying out to Santiago today to meet up with his daughter for a few days vacation, and expects to return home to Oregon by Dec. 13 and wrap up this blog with additional words and photos.In the meantime, if you have questions for him, feel free to leave them as comments to any entry here.

Before the cruise, Mr. Nishimura’s 4th grade class at Ulloa School in San Francisco colored Styrofoam cups as part of a unit on the oceans. Dr. Kate Stafford volunteered to bring them along the cruise. They were attached to one of the box cores taken in Drake Passage to demonstrate the effects of depth (pressure). The standard 4.5-inch cups were reduced to just over an inch in size. The box
