How geochemistry tells about climate and environments

In July 2007 was the first International Sclerochronology Conference in St. Petersburg, Florida. It was great to meet people who do such similar research, turned out they’re really nice as well. And shell researchers like to eat their subjects, so oyster bars were frequently visited. Even more fun is to put a bunch of these people on a beach. On this specific one (St. Pete’s Beach) there were small coquinas (Donax variabilis), which live in the surf en bury themselves in the sand after each wave. Here’s a video showing some. You can hear some very excited scientists in the background.
