This weekend we will be streaming video from our volunteer, Nam's research cruise in the Caribbean. Come to the Marine Exhibit to check it out on the big screen, or stream it at home on your computer. Here's an endorsement from the travelling man himself:
“As a volunteer of the
PTMSC, I am proud to represent Port Townsend as a science intern aboard the E/V
Nautilus during the last two legs of the 2013 expedition in the Caribbean. We are currently examining the impacts of volcanic eruptions on the seafloor off the coast of Montserrat. By next week we will be exploring the most active and dangerous submarine volcano (Kick’em Jenny) off the coast of Grenada. The tools and instruments we are using include multi-beam SONAR and sub-bottom (ground penetrating RADAR) for seafloor mapping, as well as the ROVs Hercules and Argus to collect images, videos and samples from the seafloor.

from, and if you address it to me, our educator will make sure I get your
message!”
We can't wait to watch the ROV footage this weekend and we hope exhibit visitors enjoy sending in their questions and messages to the researchers on the Nautilus.
I'm curious if the type of sonar being used in the volcano study is the same kind of sonar known to harm marine life? (Not trying to start anything - I'm genuinely curious.)
ReplyDeleteVery good question Connie. I asked the same thing when I got on board. The answer is no, ours are not the controversial type the Navy is using off the west coast. They are low in power, have a small range, and are on a different frequency then what marine mammals use to echo-locate and communicate.
