What a day.
This morning I could hear the wind blowing through the trees, but being the noob I am, I didn't think about what that meant for the morning snorkel, so I got all suited up and got in the water only to find that I couldn't see anything. So I spent the rest of the day in the wind with a wet wet-suit. Luckily for our lab today we were taking sediment cores at low tide. We were studying the change in invertebrate density with distance from reef patches. It's an interesting concept. I've spent so much time studying patches themselves and the theory of island bio-geography that actually focusing on the areas around the islands was a whole new idea. I was surprised by the results, which was cool, that hasn't happened in a long time. Common sense would make you believe that more invertebrates would be further away from the reef patches, since fish, their natural predators, tend to stay closer to reef patches, but that was only true for arthropods. Mollusks are more common closer to the reef patches. My personal theory for this is that mollusks are protected by their shells, so face less threat from fish, and are slower/more bulky, and need protection from the current. But then again, I know very little about marine biology.
I don't have the motivation to write very much today, so until tomorrow!
