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.

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 …

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 …

Physical Oceanography Video: We won’t measure the flow speed boundary layer directly, but instead will measure concentration boundary layers using the handheld profiler introduced in Module 4 (Fig. 3). We will test how variable the profiles are around the habitat …

Sponges, the Reef’s Filters Video: The history of science shows that science often advances the fastest when people make new tools that allow the test of new questions, rather than vice versa. One tool developed by Dr. Patterson is a …
