The Southern California Coastal Ocean Observing System (http://sccoos.org/) gathers live data about winds, waves, surface currents, temperature, and water quality, and makes it available to everyone. In this piece, Oceanographer Art Miller tells us about this system, and about how America's Cup sailors can use this kind of data and modeling to improve their race performances.

Pouring concrete is an ongoing feature of construction at the Piers. This footage, captured in July 2011, shows the well-choreographed process involved, from pumping the concrete into rebar-latticed slabs via remote-controlled overhead boom, to vibrating the concrete to get rid of air pockets, to flattening the surface using 2x4s (“screed”) and rakes (“come-along tools”), to tamping in (“jitterbugging”) bits of sand and gravel, to the final smoothing and leveling of the finished surface. This pour created an extension to the southeast apron of Pier 15, adjacent to what will become the East Gallery. How can a wind-powered sailboat move faster than the wind? Why do the America's Cup sails look like airplane wings? With the beginner in mind, Exploratorium senior scientist Paul Doherty introduces the basic physics of sailing and sail design. In an unlikely corner of industrial southeastern San Francisco, a herd of 60 goats gambol on a 10-acre site ringed by a rail yard and a cement recycling plant. Meet the movers and munchers behind City Grazing, a local “rent-a-goat” service that provides an ecological alternative to lawn mowers and herbicides.

This past August we recorded video of the Exploratorium's new home from a boat about 100 yards off the back of the piers. This After Dark, the Exploratorium hit repeat on favorite memories. Guests explored the fascinating worlds of reminiscence and repetition—and then backwards skated through their own nostalgia on our temporary roller rink. A news clip by NBC on the Exploratorium's move to Pier 15 On August 4, 2011 After Dark Blue delved into the color of cool with explorations of indigo, underwater vision, color photography, and blues performances by Lady Bianca, Bobbie Webb, and Fillmore Slim. Join Exploratorium educator Ken Finn as he unlocks the mystery behind the black sand (a.k.a. magnetite) at Ocean Beach. This piece explores the origin of magnetite in the Sierra Nevada mountains, its journey down the Sacramento and San Joaquin rivers to the Bay, and the interesting physical properties of this mineral, plus some fun things you can do with it. Framing of the Exploratorium's Observatory Building, the only completely new construction at at the piers, began in April 2011. Iron workers placed various sizes of steel beams in piles around the concrete base of the Observatory. Then, while a crane raised and held each beam aloft, the workers used metal spikes to line up the holes of the beams and inserted bolts, tightening them down to tie the structure together. Because the Observatory Building is less than two stories tall, the iron workers were allowed to shimmy across the beams without harnesses. Once this process was finished, the beams were plumbed and welded together.
