River Green for a Day

It all started with Plumbers Union Local 130 about 60 years ago and the city of Chicago is still dyeing the Chicago River green in celebration of St Patrick’s Day. Probably not the most environmentally-friendly way to celebrate, but it does stand out:

Undersea’s Filmmaker for benthic sampling

We have been working with UOW (University of Wollongong) and DPI (Department of Primary Industries, NSW) to film and sample benthic assemblages off the Wollongong coast, and plan to be back at it again next week.  We use our own customised ROV, dubbed Filmmaker, fitted with stereo cameras, a Newton Gripper, downward-facing cameras and lasers.  Filmmaker has been used for filming/sampling when the vessel is stationary, and as a controllable towed unit using a forward bridle.
