During the NA174 expedition, co-lead scientist Dr. Annette Govindarajan from Woods Hole Oceanographic Institution is sampling for environmental DNA (eDNA) to explore the deep-sea biodiversity in the Marshall Islands region. She will be using the Multipuffer eDNA sampler built by Aquatic Labs, which can filter large volumes of water, enabling greater #biodiversity detection than conventional Niskin bottle sampling. The sampler will be integrated onto the ROV Hercules for use during surveys.
