While exploring the Marianas, OET's ROVs Hercules and Little Hercules, alongside WHOI's AUV Sentry and Waveglider, will work together to put eyes on parts of the seafloor never before surveyed. For the first expedition (NA179), we'll be focusing on the southern area east of the Mariana Trench. The next expedition, NA180, will focus on sites further north.
