Welcome back, Chrono Art Clock! What? It’s not the clock that befuddled Oscar Madison on “The Odd Couple” in 1973 (appearing at 12:45)? No. But it does tell you if it’s a safe time to be in the water! So what are we looking at?
ANSWER TO LAST WEEK’S SATURDAY SCIENCE STUMPER:

Much like the Vulcans of “Star Trek,” horseshoe crabs have blood that uses copper instead of iron to transport oxygen. It also happens that their blood is a fantastic tool for detecting bacteria that might contaminate pharmaceutical instruments and injections. Horseshoe crabs (not really crabs at all) are captured, tapped for blood to be used for this purpose, and released. For those of us who are less bloodthirsty, you can see their moon-driven, ancient mating migrations this weekend along beaches throughout NYC! More about our local horseshoe crabs at Nature Calendar.
Kayakers in the summer of 2017 will love paddling under Staten Island’s grand New York Wheel, the tallest observation Ferris wheel! How cool will that be? But we Newtown Creek paddlers might be even more grateful to have something like this less-flashy wheel. What do you think it is?
Intrigued by these images? Then head over to our Facebook Fan Page (https://www.facebook.com/HarborLAB) to enjoy the challenge of our Saturday Science Stumper! Each week we present an image that relates to our estuary and watershed ecosystems, plus a hint to help you identify it. The following week, we provide the caption.
HarborLAB is an environmental service learning organization, not a club, so we’ll shamelessly geek out on the wonders of science around us. Join the fun!
