Diving can be a wild ride that evokes more than a little trepidation, especially in the Pacific Ocean's famously big, cold waves. Waves that are otherwise fun for my weekend surfing can turn a...
In the late 1990's, researchers at the Woods Hole Oceanographic Institution (WHOI) invented the D-Tag —a radio device that can be attached by suction cups to a whale's back. Using a tiny underwater...
Tectitethya crypta (formerly known as Cryptotheca crypta ) is a large, shallow-water sponge found in the Caribbean. It was first studied for medical purposes in the 1950s when few scientists or...
You’re out to sea on a 355 foot platform, and suddenly one end begins to slowly tip underwater. Should there be a call for evacuation? Are you sinking? Not if you’re on FLIP – the FLoating Instrument...
