Lander

Near the Jan Mayen vent field, the CGB will deploy an acoustic lander on the seafloor using the Aglantha ROV. The lander contains a movable acoustic transmitter and receiver that can scan through a large volume of water, so that bubbles of gas can be easily detected. With the sonar scanning continuously for several days, the scientists will be able to quantify the flux of gas bubbles escaping from the hydrothermal site and better understand the flow of magmatic gasses from this unique hydrothermal system.
