The crew of RV Thomas G. Thompson deploys a Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) in July 2019 on the Shelfbreak Productivity Interdisciplinary Research Operation at the Pioneer Array (SPIROPA) expedition.
As MOCNESS tows behind a research ship, each net can be opened and shut independently so that it samples a discrete patch of water. The researcher chooses exactly when by using the environmental sensing system. This is an array of sensors mounted on the instrument frame that relays water conditions up to the ship in real time. The data also help researchers match what they find in their sample to the physical properties of the seawater.
