They're active at night, so we need to find them before the sun comes up. If we do find them, we'll be able to start doing some of our urchin feeding experiments. We just want to make sure there are urchins out there first before we spend too much time setting the experiment up. Now, it's time to get some sleep. I can't wait.
Waves can make the habitat feel like a swinging basket.
Sleeping should be interesting. Even though the habitat is heavy and well anchored, we can still feel the big waves from the surface. Every couple of seconds, as the depth changes when big waves roll over us, we must yawn or shake our head to clear our ears, just like you do in an airplane gaining altitude. Also, big swells tend to rock the habitat. It's a little unnerving.
