Over the years, I've taught many courses on hydrophone use & sound analysis. Now that I no longer build hydrophones, I haven't taught any classes and I would love to teach more! Rather than deciding what the courses would entail myself, I'd like to hear what you'd like to learn. Please let me know!

This rule will render the EPA unenforceable. Please comment on the rule, and then call your representatives and tell them not to allow its implementation, for the whales and for the planet.

One of the people fired from NOAA today is the director of the Ocean Acidification Program. That program also leads the U.S. government's effort on marine carbon dioxide removal (mCDR). The destruction of American science is incomprehensible.

Nice systems! Was Rodney Rountree involved with any of your work? He was the person who encouraged me to design and build the first RUDAR back in 2001. He's been working with a few people at U Vic and is the main fish sounds person I know.
