Robots are being increasingly being used to gather data at sea. Here is a fascinating undersea glider design in use by the Coastal Ocean Observation Lab (COOL) at Rutgers University, which uses gravity and buoyancy for propulsion, allowing to it remain at sea for months at a time while it records water temperatures, depths, salinity and more, sending the data to shore by satellite phone each time the robot periodically surfaces. Changes in water temperature as a function of depth have proven to be highly useful in predicting hurricane intensity.
The 6-foot-long, 115-pound autonomous underwater vehicles (AUV) operates as underwater gliders. A small amount of water in pumped into the forward end of the glider when on the surface, making it slightly negatively buoyant. As the robot sinks, lift off the glider wings gives it forward motion. As it approaches the bottom, the water is pumped out, making it slightly positively buoyant. Again, lift off the glider wings generates forward motion as it moves slowly toward the surface. These gliders are the latest version of “Slocum gliders.” In 2009, the Rugers’ Scarlet Knight glider successfully transited the Atlantic.

Award-winning architect Dame Zaha Hadid has designed a family of super-yachts with a skeletal superstructure for the German shipbuilders Blohm+Voss. These are the first super-yachts designed by Hadid who is known for a wide range of project including the Roca London Gallery, the BMW Central Building in Leipzig, Germany, MAXXI National Museum of 21st Century Arts in Rome and thethe Aquatics Centre built in London for last summer’s Olympics.
