Lagoon Survey

Since we got the rest of our stuff today I was able to get trained to survey lagoon. To do this we need at least 2 transect tapes, a ruler, waterproof paper, something to right on and a pencil.

To complete a lagoon survey we had to take a transect tape out 200 meters (m) and at the 10, 25, 50, 100 and 200 m spots take out another transect tape and go out 50 m perpendicular to the long tape. Then once we did that we had to count all of the slow moving animals that we saw, such as sea stars, sea urchins, sea cucumbers, crabs and other such animals. For the sea cucumbers we had to go down and get a relative measurement in cm. Then for the other animals we had guess the size.  We would transcribe the number of animals along with their sizes for every 5 m and we would also need to saw the percent coverage of sand, coral, coral rubble, rubble and rocks. Once we did the 50ms for all of the points then that lagoon was complete. 🙂
