Day 14: Island Cleanup

Today was our last day at the Glover’s Reef research station. I can hardly believe it! Today, we combined doing a little bit of cleanup on the island with our final experiment of the trip. we looked at the density of trash in several places on the island, hypothesizing that the regions facing into the atoll would have less trash on the beach than the areas facing outwards, towards open ocean. We went to three sites and took pictures and then cleaned them up a bit. We filled six large trash bags in total, but if we had had more we probably could have kept working for days. Lots of plastic had accumulated. When we got back, we analyzed our photographs and made our final poster. Looking at our pictures, we didn’t see a distinction between the different beaches on average. We estimated percent coverage of trash using evenly sized squares and still couldn’t see a difference, but it’s possible that our methods were imprecise or biased.

After lunch, we dissected lion fish. Lionfish are invasive to the Atlantic and can pose a huge threat to reef ecosystems, so removing them is actually doing a service—it’s another type of cleanup, in a way. It was cool to look at all the different internal structures of the lionfish. My group had a medium sized lionfish so we were able to make out all the organ. We even looked at what was inside our lionfish’s stomachs, and my group’s fish had four smaller fish partially digested. It was hard to make out what they were, as some were in a pretty broken down state, but there were a lot of them. One of them might have been a wrasse based on coloration. It was very cool to see. We removed the head and got a lesson on how lionfish suction feeding works as well. After, we turned them over to the professors, who made them into a delicious ceviche.

After that, all that was left to was pack. It’s incredible that the trip is drawing to a close—it feels like it’s gone by so fast, but it’s also been jam-packed with tons of cool and interesting activities. I got to refine my scientific skills in a beautiful location. There were some uncomfortable parts, sure, but overall it was an incredible experience. Tomorrow we’re leaving at 6:00 AM. I’ll have more to say in my final blog, but my impressions now are definitely that this experience was something I am lucky to have and something that will be tough to top.

Mondays are trash

Contrary to this blog’s title, today was an exciting day! We went out this morning to the fore reef, which is the area of open ocean that’s right outside of the atoll. There, since the waves are stronger and the water is deeper, the organisms are typically much bigger, as they need to be stronger to withstand the greater wave energy, and they have more room to grow upwards. We saw some really cool organisms from a distance because the bottom was maybe 70 feet below the surface and none of us (except the water safety officers) could hold our breath long enough to get to the bottom. Some of the cool organisms we saw included comb jellies, which were floating near the surface, and if you looked really closely, you could see that their combs were lit up with electricity. We also saw a school of medium blue fish that we weren’t able to identify, a sea turtle, most likely a green sea turtle, that was just sitting on the bottom, and a huge barrel sponge. Unfortunately, I did not see any brown algae, as it is too small to see from 70 feet above the reef. surprisingly, I saw minimal sargassum, which I think was due to the fact that the waves were so choppy.

Unfortunately, the weather wasn’t really cooperating with us, so we had to head out pretty quickly. Lucky for us, that meant we could get the nightly presentations done in the morning in anticipation of a possible night snorkel.

The afternoon was a whole other ball game. Last night, we heard from the Belize Fisheries Department manager, and he spoke a bit about starting beach cleaning efforts on Middle Caye. Today, we did a beach clean up, but being TFBs, we had to incorporate science somehow! You can read about our research below 🙂

I was doing clean up in the mangrove area behind the kitchen, and there was a lot of trash! It was sort of sad because even though we had two giant trash bags overflowing with trash, we had hardly made a dent. We spent the whole afternoon doing the beach clean up, sorting the trash, and weighing it, before putting the trash back into the bags so they could be properly disposed of. The people at the Coral Graveyard also found a box fish skeleton!

After the trash shindig we finished the last presentation, and then, courtesy of Nate, we got to watch a hermit crab change shells! I had seen videos of it yesterday in Lilliana’s crustacean presentation, but it was cool to see in real life. We then went to dinner, and since the weather wasn’t looking good enough for a night snorkel, we hung out and talked to Ruth, the water safety officer, about her experiences as a native Belizean, as well as the natural history of the country.

While most Mondays may be trash, today was certainly a good day! Tomorrow is the last full day on the reef, and we have a lot to do, so I will keep you all posted!

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!

Beach cleanup and backreef

Beach cleanup was on this morning’s agenda, and, being Rice students, we also weighed and separated all the types of marine debris and analyzed the results. The amount of garbage on the shore was astounding; we filled 6 garbage bags in an hour, and this is on a beach that is in a protected area and cleaned weekly. We only made a dent in the amount of debris accumulated on the island’s shores. I guess the take-home message to anyone reading this would be to limit your use of plastics as much as possible, stop using styrofoam, and be very careful about where your waste ends up (even properly disposed of trash often ends up in the ocean).

We went out to the backreef again today to document some coral colonies. I saw some more split crown feather dusters, spaghetti worms, a christmas tree worm, a teeny tiny star horseshoe worm, and finally a free-moving worm (as opposed to the others, which are tube dwelling). The fireworm is a marine worm that belongs to the same class as the feather dusters and fan worms but looks more like a caterpillar. It is red with white tufts, and, true to its name, will sting you if you touch it.
