When the research vessel Rachel Carson set sail for Southern California last week, it was equipped with two autonomous underwater vehicles (AUVs) to perform very different kinds of missions. One AUV is mapping the seafloor to identify areas with interesting chemical features, such as gas venting from the seafloor. The other AUV will work closer to the surface, following harmful algal blooms and collecting water samples and information to allow comparisons of ocean systems in Southern California with those in Monterey Bay.
