Deployment of four Ecological Acoustic Recorders in the MIRC (Sept 2011)

About

In September of 2011, four passive acoustic monitoring devices were deployed in the Marianas Island Range Complex (MIRC). These Ecological Acoustic Recorders, or “EARs”, were developed by Marc Lammers and Whit Au at the University of Hawai’i/Hawai’i Institute of Marine Biology. The dates, locations, and deployments depths for the four instruments are summarized in Table 1. Deployments were made to the northwest and southwest of Guam, one to the north off Saipan, and one to the southwest of Tinian.
