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, …

Movie of recirculating heated flow chambers used by Dr. Patterson and his team at Aquarius to investigate coral bleaching. Second part of movie shows corals being removed from the chambers to delicately sample the tissue of the coral, to test …

Video of demersal zooplankton from Jamaica, attracted by a dive light.

Fetch Sea Grass Video of the Fetch1 Autonomous Underwater Vehicle sampling the water column not far from Aquarius. This kind of maneuver is called a ‘yo-yo’. When you combine a ‘yo-yo’ maneuver with ‘mowing the lawn’, an AUV can rapidly …

Fetch Cam Video of a view from the nose camera on the Fetch1 AUV as it follows the terrain a set height above the bottom near Conch Reef. Right hand image has been cleaned up with the Retinex algorithm courtesy …

Turbulent Fluff Body Video from the Multimedia Fluid Mechanics project of how a roughness element can make eddies which help transport fluid at right angles to the substrate. The graph shows a measurement of the shear stress (force/area) generated by …

Wake Cylinder Video from the Multimedia Fluid Mechanics project of flow past a cylinder showing the turbulent, recirculating wake on the downstream side. Aquarius sheds a similar wake (as do the corals we examined in Module 3).

Sponge Feeding Video of a scientist sampling water from a chamber containing a sponge in Lake Baikal, Siberia. As the sponge continues to pump water through its aquiferous system, the concentration of small particles, the picoplankton, should drop. Surprisingly, Dr. …

Complex Coral Flow Video of the complex flow over the expanded surface of a feeding reef coral, made visible by a collimated sheet of light fluorescing a dye released close to the coral surface.

Burrowing Cerianthids Video: An example of a passive suspension feeder, some burrowing sea anemones (Cerianthus sp.) off the coast of California. Note how the long tentacles, equipped with stinging cells (cnidocytes), oscillate in the wave-driven flow.
