Cruise Description

Purpose

We will spend three days exploring the Monterey Canyon slopes and surrounding areas. The primary objective will be to visit the whale fall site at 2890m depth (31 km offshore) to further characterize changes in the biological community. The secondary objective is to investigate seeps and biological processes between 2500-3100m depth in the Monterey canyon. If necessary, based on findings, we intend to collect sediment and animal samples.
