June 7: Afterwards



June 7, 2013: After the trip-Looking back through my pictures of corals, it’s clear that I learned quite a bit about identifying different species. I had never appreciated the diversity of corals before I had to really study them underwater. I can now identify at least 30 species of reef-building corals that live in the Florida Keys & Caribbean. It was fascinating & I am excited to continue to learn about corals in the keys over the next several weeks, where I will be helping complete the monitoring efforts in the upper & lower Florida Keys this summer. In four days of diving, I logged over 12 hours of bottom time. I also observed lots of interesting fish & watched a lot of interesting fish behavior. Whenever I think there’s nothing new to discover in this world, I go diving & I always see something new or learn something new. Often, I observe something that no one else has bothered to study before, and that makes all of the hard work worth it!











June 5: Coming Home




June 5, 2013: Day 6 of work- The weather continued to deteriorate overnight, but we only had 1 more regular site to go, so we stayed overnight to see if we could sneak in the work at that site before heading home. Unfortunately, the site that was left was very shallow & on the ocean side of a fringing reef.  The captain was able to anchor the boat, but with waves crashing over the reef, there was no way the work was going to get done. Sometimes you have to let safety win out over getting the data. We dropped off the park ranger that had been with us at Ft. Jefferson. Both the science & deck crews worked hard to secure all of the loose gear for rough seas.  Around 10 am, we headed out of the Dry Tortugas & back toward the dock in Ft. Myers Beach. It was a pretty rough ride with 5-6 foot waves crashing into the starboard side of the boat throughout most of the trip. Most of the scientists slept the whole way home, while some of us sat in the salon & watched 2 seasons of The Big Bang Theory on DVD.  There’s not a whole lot to do on a 12-hour transit in rough seas…
We arrived at the dock around 11 pm, by which time the weather that had been plaguing us for days had finally gotten a name. Andrea was the first named storm of the 2013 hurricane season.  We loaded up our pick-up trucks in the rain & headed for St. Pete, 6 people in an extended-cab truck. The crew dropped me off at home around 1:30 am & I promptly feel asleep, exhausted from extensive diving & rough seas.

June 4: It's like Friday, but not

Original plan was the bow...
June 4, 2013: Day 5 of work- I woke up pretty slow & sore today. Several days of diving & boating take it out of you. Our mission for the day was Mayer’s Peak & The Maze. Weather conditions were starting to deteriorate & work was no fun. We hadn’t seen sun in about 3 days, so all of our gear was soaking wet. In addition, the deck of the boat is covered in outdoor carpeting & that hadn’t had a chance to dry out in several days, either. Things were wet & tiring. Some of the divers were trying to keep their spirits up with overnight pranks, and that was working pretty well. We were still laughing.
Arriving at Mayer’s Peak, I attempted to help set up the transects. However, it seemed like nothing was particularly going my way. I looked for at least 10 minutes for the transect I was going to set up & never found the stake. Eventually, Vanessa came along rolled out a measuring tape to help find it. Even with that, it still took both of us a few minutes to located the stake in the forest of soft corals. Once that transect was set, I moved over to the one I had planned to survey. I started on the opposite end from everyone else in order to stay out of the way. I made it less than halfway along the transect before having to return to the boat for more air. I returned to the site & never did finish before my 2nd tank ran out. After this experience, I had a conversation with the boss because I was pretty frustrated. I felt like I’d been working hard for several days, but never really figuring out if I was making any progress on identifying corals. It was always difficult to compare the datasheets I’d filled out to those that the real data collectors were completing.
We hatched a plan to directly compare my data to that of the real data collector for that site. We moved to the final site of the day, The Maze. I was already tired, but we had a plan that I hoped would help me to see which corals I knew & which I didn’t. However, the weather continued to be nasty & the current was kicking. I jumped off the boat & thought I knew where the marker buoy was. However, it turned out that I got swept downcurrent. By the time I realized that I wasn’t going to find the reef & surfaced, I was 100 yards away from the boat & continuing to float away. I sank under the surface slightly & kicked as hard as I could to get back to the boat. By the time I returned, I was winded, scared & embarrassed. I was supposed to show that I could do this. I had to have a buoy thrown to me & get dragged in. I felt like a wet rat. Of course, most of the divers were still on the boat so I was doubly embarrassed. The captain, who’s been driving this boat for over 20 years, wisely forbade me from getting back in the water today.

The salon: white balanced for 80 ft
The salon: normal light...
Downloading my camera, I noticed that I had left the white balance set for 80 ft of depth. Anyone who has studied oceanography "knows" that red disappears first and has seen an image which looks like this. However, I find it to be a totally different scenario to actually see it happening. I set the white balance on the camera underwater by pointing the camera at a white datasheet & telling it, essentially "this is white." The camera then automatically compensates the colors so that what I told it was white, actually seems white. It adds enough additional color to the image to make the colors look "normal." However, when you bring the camera back to the surface, if you don't change it, it is still set to compensate. Noticing this, I took a few pictures of the salon on the boat. This is how much red & purple had to be added for the images from yesterday to come out looking "normal." 

June 3: Deep dives



diseased MCAV
June 3, 2013: Day 4 of work- Black coral rock. This is a great site that is pretty deep. 80 ft to the bottom. The sites were up on top of the pinnacle, but there were big holes that went another 15 ft. There were 10-15 species of corals. SSID, MFAV, MFRN, MCAV, PPOR, MDEC, SMIC, DSTO, PAST, DSTR, CNAT, AFRA, SCUB. I didn’t have a whole lot of time to look around after we finished. I didn’t even get a chance to finish the work, but since I’m still just practicing, it was ok. It’s a little disheartening, but I think I’m picking it up faster than a lot of people who start from nothing.

After the work dive, we scooted over 100 yards to a site that the park had marked & put a mooring buoy on. It was a place none of us had ever been, so it was cool to explore somewhere new. It was a beautiful site. There was a very distinct thermocline around 65 ft, so steep that it shimmered when you looked through it. It was pretty cool on the bottom. However, the top of the site was nice and warm. I took my camera with me and took a ton of pictures. I was enthralled watching fish do their thing. There were creole wrasse that swam around in pairs. One adult would swim very close to one juvenile. I thought they were keeping the same partner, but as I continued to watch, I realized that they would sometimes switch partners. Not a behavior I’d ever noticed before. There are still so many things we don’t know about the underwater world. It continues to amaze me.
