Project SeaCAMEL – Module 6 – Background Info – Fetch Sea Grass
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 …
Project SeaCAMEL – Module 6 – Background Info – Fetch Cam
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 …
Project SeaCAMEL – Module 5 – Background Info – Turbulent Fluff Body
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 in Project SeaCAMEL (Module 5) – Background Info
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).
Project SeaCAMEL – Module 4 – Sponge Feeding
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. …
Project SeaCAMEL – Module 2 Background Info – Complex Coral Flow
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.
Project SeaCAMEL – Module 2 – Background Info – Burrowing Cerianthids
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.
Project SeaCAMEL – Module 2 – Background Info – Baikalsponge
Baikalsponge Video: An example of an active suspension feeder, a sponge (Baikalospongia bacillifera) from the world’s oldest, deepest, most voluminous lake, Lake Baikal, Russia. Note how the dye is pumped at high rate from the excurrent pores, the oscula. Later …
Project SeaCAMEL – Module 6 – Aquarius as an Artificial Reef
Aquarius as an Artificial Reef Video: We hope this classroom will be a visual treat. In addition to the fish census, and interesting fish behaviors we will see, we hope to fly the Fetch1 AUV past Aquarius several times. We …
