Today’s Objectives: We completed three CTD deployments yesterday and a multibeam mapping survey overnight and are underway to shore.
Harvesting Energy from Hydrothermal Vents Dave Dyer is an engineer at the Applied Physics Lab at the University of Washington where he thinks a lot about renewable energy, specifically, harnessing energy from hot vent fluids to create a source of electricity on the ocean floor. With Keith Scidmore and Jeff Breedlove, Dave is part of a team of engineers who are installing two different devices that could eventually result in harvesting energy from the hydrothermal vents of Axial Volcano. The instruments are in the process

One of each of the EHDs has now been installed and will remain at Axial Seamount for another year. But the group doesn’t want to wait a year to get data, so they launched a communications buoy early in the cruise (see blog entry on Sept 4th). The EHDs on the seafloor transmit their data acoustically (with sound waves) to the communications buoy, which sends data to a satellite that transmits the information to the team by email (see schematic diagram above left).
To learn more about the team who are here at Axial Seamount, working to install the variety of instruments involved in with the EHD, see the “Science Team” blog entry and the Axial Volcano Buoys blog entry from September 4.
