Day 6: Tackling the Forereef

After checking the weather report, this morning was the best chance we had to go and see the forereef. The forereef is the region of the barrier of coral around the atoll that is facing the open ocean. Outside of the protection of the wall, the ocean waves are far more intense. The boat ride over was a tad more nauseating than others, and the swells were quite an intimidating sight to see before jumping in. However, once in the water, the waves were far less burdensome than I expected. The water was significantly deeper than any other region we have been before. The reef was ~70’ down, but it boarded a significant drop far deeper than I could see. There was a beautiful school of blue fish that we were able to swim through, and the water was littered with small translucent and barely glowing ctenophore. There were massive colonies of stony corals just below us. I would imagine they’re many of the same species I encountered in the lagoon, but were able to grow to larger scales because of the deeper conditions. In the shallow patch reefs, the corals have to contend with very bright light, harsh UV, and warmer temperatures. Yet although these colonies were larger, there were still obvious signs of disease. The distance was too far to see any detail, but the lesions were quite evident from above. I truly love how throughout this trip we continue to explore new places each time.

After returning back to land, we worked to clean up debris from some of the beaches of the island. Although messy, we collected, sorted, and analyzed the trash which accumulates on the shores. The debris either has to be disposed of on-site or shipped back to land, and it was quite interesting to learn that they burn everything possible (including plastic). Between this activity and Nate’s excellent talk describing marine debris, it left me questioning my participation in convenience consumerism. Every toothbrush, bottle cap, plastic container, bag, and more will continue to persist in the environment for hundreds of years. In this afternoon’s lecture, a chart showing the largest marine plastic polluting countries in the world were not the largest plastic consumers. The west appears to have superior management of waste, yet western countries continue to ship single-use plastic waste to other regions of the world for “recycling.” Yet in many of these cases, it’s this plastic that is ending up in the oceans. So who is truly to blame? The countries where the trash is released into waterways due to relatively poor management, or the western countries which ship their waste out of sight with the facade of recycling to lessen the social shame of convenience consumerism.

Just before dinner, we saw the rare sight of a hermit crab changing shells. Watching it shift its squirmy shrimp-like body from one shell to another was fascinating yet a bit unnerving. During dinner, one of our Marine Safety Officers Ruth gave us an in-depth information session about Belizean history and her career path to being here helping us. It was super fun, and I hope to find a career I am in love with like she is with hers. But on that note, I am now questioning what aspect of biology I want to pursue. I have always planned on going into medicine, but my experience during college has pushed me towards a love of research. I understand that most research is not like this, out on a gorgeous island, yet I wonder if research overall is something I would rather do than dermatology. Studying papers and information about coral diseases was a great time, and I think fulfilled much of the same curiosity I am hoping to satisfy with a career in medicine. But understandably no one wants a truly creative doctor, as medicine has some pretty ridged defined boundaries for most disciplines. Yet the goal of research itself is to push our current boundary of knowledge and make the unknown known. Depending on how the rest of my time at Rice goes, I could see what I thought as my career path shift in the direction of scientific and/or pre-clinical research. Overall, this class continues to be an incredible and influential experience.

Forereef

Trash Day!

Hey y’all! It’s Michiel again : )

I woke up this morning after nearly freezing to death last night. It wasn’t actually cold (I mean, how cold could it get in the tropics?), but my bed is right by the window and the wind kept blowing into my sheet, and I couldn’t figure out how to close the window, so that was fun. It wasn’t that bad, though, I’m definitely being dramatic. After waking up, I met everyone for breakfast, and they make the most amazing pancakes here; I was so happy when I saw them waiting for us.

After breakfast, we went to the forereef. The waves were pretty strong today, so I started getting a headache on the boat and it kept getting worse as I was in the water, but it was definitely worth it because the area of the reef we saw was so amazing. We saw spur and groove formation, a swarm of ctenophores,  and a sea turtle lying in the sand! This area was also way deeper than any area we had been to before (about 70 feet) and there was a reef drop right next to it which dropped for hundreds of feet, so we really got to test our breath-holding abilities. One of the experienced divers actually went down about 100 feet! While we were there, we saw a school of fish, but I could not get close enough to figure out what they were. They were mostly blue and larger than a damselfish or a surgeonfish, so they may have been a parrotfish, but they may have also been something entirely different. Parrotfish and other types of herbivorous fish are known to travel in schools, so it isn’t unruly to guess that these may have been parrotfish, but, again, they were so deep that I couldn’t get a very good look. It may not have been an herbivorous fish at all. If it wasn’t, then I didn’t get to see any herbivorous fish today because we were too far from the reef to see that many.

After leaving the forereef, we had a little break, then watched some lectures and had lunch. After lunch, we started coming up with a research question that would involve a beach clean-up. We ended up with “What percent, by mass, of the trash on Middle Caye needs to be disposed of off island? What area is the most efficient for collecting trash?” We hypothesized that over 50% of the trash would need to be moved off island for disposal and that the coral graveyard would be the most efficient area for trash pick-up. To collect data, Ava, Michael, Maggy, Adrian, and I went out to the bunks to collect trash for a total time (between all people) of one hour. Different groups did this at different locations around the island. Back at the wet lab, we weighed everyone’s trash bags, separated burnable trash from non-burnable trash, and weighed the non-burnable trash. With our data, we discovered that only 11.43% of the trash here needs to be removed from the island because they actually burn the plastic here, so they only remove the metal and glass. We also found out that the most efficient area for trash pick-up was the area behind the kitchen because the people there collected 16.41 kg of trash per person-hour. We believe that the reason the most efficient area wasn’t the coral graveyard was because the coral graveyard’s trash was more spread-out and it was much smaller, so it didn’t contribute as much in terms of mass. Hopefully this data can be helpful to the Belize Fisheries Department because they have plans to do more beach clean-ups on Middle Caye!

After presenting our project to our professors, we had another lecture then dinner. Right before dinner, though, Nate set a shell down in front of a hermit crab, and we saw it change from it’s previous shell to that one! It was so gross. Anyway, we stayed in the dining room until it closed because we were all talking, and then Ruth (a marine safety officer) joined us and told us about the clothes she makes and the history of Belize. She taught us a lot, and she’s been a super important part of our stay here on the reef, so we couldn’t be more thankful to have her.

After dinner, we were going to go on a night snorkel, but the weather picked up and we decided that it wouldn’t be safe to go. The group just ended up working on our blogs and field notebooks before going to bed.

Overall, today was a great day! Here’s a group picture of us washing our hands after we finished handling all the trash, a picture of Sophia, Elena, and I as we were working on our poster for our trash presentation, and a picture of an iguana.

Finally Seeing the Forereef! Cute lil Ctenophores!

Today we finally got to go snorkeling in part of the atoll that we had heard so many good things about since we’ve stayed here. Until now we had mostly been visiting the patch reefs within the lagoon, but on the oval edge of the atoll there is a huge reef called the forereef that has a huge areas of large reef interspersed between deep grooves that break the intense wave energy. The wind had actually been too strong these last few days to safely attempt seeing it, but this morning we had a rare window of opportunity, and seized it!

This area was much much deeper than anywhere we have snorkeled so far, and it was so deep that it was difficult taking any high resolution pictures of the huge corals below. But most excitingly, I was actually able to spot some little ctenophores (comb jellies) close to us! Comb jellies look like translucent jelly-like forms that don’t sting like jellyfish do, so even though we were right in the middle of a mass of them, we were just fine! It was hard to get any clear view on them because of how translucent they are, but based on what I saw, they look like the sea walnut comb jelly.

We unfortunately couldn’t stay out there for longer than about 20 minutes because then the waves picked up, and a lot of us got seasick again :(. After recovering, we heard a lecture on the effects of pollution in the ocean from marine debris such as plastics, and designed a dual research project and beach cleanup activity! We recorded the types and amount of debris we were able to collect on the shores around our island. We were able to calculate which areas of the island would be most effective to focus on for future cleanup efforts, and collect over 60 kg of trash! Here is an insanely cool photo of some very well preserved fish remains someone found during the cleanup!

Dramamine For The Win

Reef day #5 was definitely the most packed (and exhausting) day yet! There was a storm last night, so there was leftover cloudiness and winds this morning. However, conditions still looked good enough to go out onto the fore reef! I took dramamine at breakfast, and thank goodness I did. We hopped on the boat, and as soon as we exited the lagoon through a channel, we could feel the intensity of the waves. Even in the water, we were being forcefully sloshed around. Looking up, people were at all different heights among the waves.

Even with the rough conditions, I had a great time on the reef slope! The depth was incredible, especially at the drop off. I saw so many schools of fish, and I could clearly see the spur and groove structure of the corals down below! We also took a video of all of us diving down and making owl hands. Hopefully we make Rice’s Instagram 🙂

I felt a little sick coming off the boat, but the dramamine helped to keep the nausea at bay.

Later in the day, we conducted a trash clean-up (as an experiment in true TFB fashion). We collected so much trash and sorted it into burnables and non-burnables. Our experiment hoped to characterize the trash at different sites along the shore of Middle Caye as well as the general efficiency of collection at each site. We spent the entire afternoon planning out our experiment, conducting our experiment, measuring and sorting to collect data, and then making a poster and presenting it. We are hopeful that this data will help to inform future trash clean-up efforts! I also managed to get a really cute, homecoming-style picture of TFBs lined up on the stairs to wash our hands.

I gave my first presentation today! I presented my reef taxa (anemones, corallimorphs, and zoanthids), and I feel like it went really well. Everyone asked really great questions too!

Before dinner, Nate (a fellow TFB) placed a shell in front of a hermit crab for giggles. Not only did we have some giggles, but we also witnessed something incredible: the hermit crab switch shells! I was able to get it on video and am thrilled to have seen something so rare to catch.

I didn’t have any taxa sightings today, but my other sightings and experiences were more than captivating! Ruth also taught us so much about Belize at dinner! Best off-the-cuff topic lecture ever!

The fact that my eye has been twitching since around 2:00 pm is a clear sign that I am more than ready to get some rest. I’m ready to sleep as soundly as I can to appreciate my last full day on the reef tomorrow!

Rock the Boat

My stomach is strong, as are my legs, and I am now very confident in my ability to weather choppy waters on a small boat.

We explored the different areas of the reef today starting at the fore reef and the reef crest and ending the day at the back reef. The fore reef and the reef crest were so choppy. Part of the reason that the rest of the atoll isn’t as choppy is because the fore reef bares the brunt of the wave action coming from the ocean. Everything was moving back and forth constantly and it was really hard to even stay in one place while floating above the reef.

The fore reef was amazing, and we got the chance to see many rays, a nurse shark, and amazingly we saw both species of acropora (cervicornis and palmata) in the wild! Acropora were mostly wiped out in the Caribbean due to white band disease, so it was a unique experience being able to see them. We also got to see an eagle ray swim by underneath us, which made me super happy. They’re HUGE!

My camera died before we got to be on the back reef at the end of the day. They definitely aren’t as waterproof as they say they are. I opened it up and there was water in the battery!

At the back reef I saw so many queen conch (probably hundreds). I also got to see a milk conch, which is the only other conch I’ve gotten to see on this trip. While digging through the rubble on the back reef I saw a few species of cone snail living in some unoccupied shells of former molluscs.
