Science and Technology Log:
Today the photomosaic team from Stanford University, Dr. Steve Rock and Ph.D. student Kristof Richmond, stepped up to direct underwater operations.
Currently there are two known debris fields. The larger field contains the Curtiss F9C-2 Sparrowhawk airplanes, five of the eight Maybach Engines and remnants of the galley. The second debris field contains the bow end of the
The photo-mosaic will be created using a control system designed by the Stanford team to pilot the Tiburon along a series of parallel transect lines, a pattern playfully called “mowing the lawn”. As the ROV travels above the seafloor along its transect line, a High Definition Camera periodically captures images that are assembled to create the photo-mosaic. Due to the low light and at times murky conditions, the camera can’t be more than a few meters off the sea floor. Imagine trying to create a picture of your local soccer or football field by walking the entire field holding a camera at arm’s length facing straight down.
Tomorrow we will continue the photo-mosaic efforts!
