A Marine Educator At Sea

A Beautiful Monday at Sea

October 18th, 2011 · No Comments · 2011 - R/V Wecoma, Deployment, LDEO, Seismometers, SIO

We have traveled north to test two Cascadia seismometers that were deployed earlier during the first leg during July. A specific frequency of sound (between 9 and 13 kilohertz) is sent down to check if the instrument package is working. Sometimes a fishing trawl can flip over the seismometer, rending it useless. If the instrument is working, it responds with a series of audio chirps that are picked up here on the Wecoma.

So far we have deployed five Cascadia and four Abalone seismometers. Another five are scheduled for deployment through the night.
