Research Dives

Data collection for independent research begins.


Dive 1: Research buddy's dive. We went to about 30 feet and laid a 30 meter transect to conduct a fish survey and Diadema (sea urchin) survey. It went really well even though we didn't see the species he was looking for. I got to see 2 spotted drum fish, which are really cool fish. 

Dive 2: My research project. Today's dive was testing out all the methods I will be using during the duration of the project to see how long it will possible take me to gather data so I can have a better idea when planning my dives. So, I started off with a fish survey for about 5 minutes recording the different fish species and sessile invertebrates. After the fish survey, we laid rugosity transects. This was an interesting task to accomplish. I had to really keep track of my buoyancy because I was carrying a lead rope while unwinding it. Therefore, I had to have just the right amount of air in my BCD and adjust my position with my lung volume. The final step was to take photo quadrat samples so I can determine coral cover and algae cover. Overall, it was a very successful dive.
