Sponge Flux Video: Two scientists measuring the flux of water through a sponge at a deep dive site in the Gulf of Maine
Movie of two scientists working rapidly at a deep site (35 m) in the Gulf of Maine, making measurements on the velocities of excurrent jets exiting from the sponges, taking samples and assessing the size of the excurrent openings, oscula, in order to calculate the flux of water through the sponge. These same sorts of measurements will be made during this classroom segment, and will allow us to estimate the metabolic rate of the sponges we examine.
