Five years ago this month, my pal, BB contributor, and IFTF colleague Ariel Waldman created Spacehack, a directory of projects through which anyone can participate in space exploration. It was a very influential endeavor, igniting many people's interest and excitement in space research and how we can all get involved even here on terra firm. Today, Ariel has launched Seahack, a similar site to spur participation in sea exploration! From DIY underwater robots to crowdsourced analysis of deep-sea videos to a project aimed at decoding the language of whales, Seahack is a great way to get your feet wet (sorry) in ocean science even if you're a landlubber like me. Congratulations, Ariel!
