Trash Day!

Leave a comment

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.

Unknown fish (possibly herbivorous)

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.

I feel cool

Leave a comment

Today I feel very accomplished. We did a coastal trash survey and cleanup to find the most efficient cleanup location and figure out what portion of the trash could and couldn’t be burned on the island, and I found this!

We think it was a box fish or cow fish. Either way the skeletal structure exoskeleton thing is amazingly cool.

Also, on that trip I picked up some shells I thought some hermit crabs  might enjoy, and when we got back I got one to move in! We were all standing there with our breath held as it inspected the whole shell inside and out, and we let out a cheer when it pulled itself out of its old shell and into mine!

The other major even for the day was that we went to the edge of the atoll, known as the reef crest to snorkel. The waves were massive and rather scary, but it was also really cool to see such deep water with massive coral structures on the bottom.  There was also a massive drop-off at the edge of the reef crest that felt like looking down a cliff to nothingness. Some highlights included seeing walnut comb jellies and a sea turtle sitting on the bottom! There was also a large school of what looked like possibly parrotfish swirling around us! Unfortunately it was too deep for me to be able to decipher the green algae on the bottom, but tomorrow we should snorkel in shallow water so hopefully I will see some there!

De-debris-ing Glover’s Reef

Leave a comment

First thing this morning, we went out on the boat to snorkel the fore-reef (the part of the reef that faces the open ocean)! I was nervous about snorkeling in waters so deep and so rough, but I actually had a super good time, and I got to see some things for the first time: I spotted a sea turtle way down on the ocean floor, we saw some Walnut Comb Jellies floating just beneath us, and I saw loggerhead sponges (Speciospongia vesparium)! I wish I was better at diving down beneath the water, so I could have gotten a closer look…

After lunch (alfredo pasta, salad and bread), we were tasked with designing an experiment centered around cleaning up marine debris (trash) from Middle Caye in Glover’s Reef. Being an island relatively far from the mainland, marine debris is a significant problem because the Gulf of Honduras Gyre (a water current) funnels all kinds of trash from the mainland directly onto the shores of Middle Caye.

In total, we collected 64.5 kilograms of trash from three different sites across the island, including 7.4 kilograms of glass and metal, which will have to be taken back to the mainland on a boat. Part of the problem for Middle Caye is that it simply isn’t economically feasible to charter boats specifically for transporting trash, so a lot of trash (including plastic and Styrofoam) is burned right here on the island.

Finally Seeing the Forereef! Cute lil Ctenophores!

1 Comment

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!

D-6 Fossils, trash, & a naked crab?

Leave a comment

Hi everyone!

Much like other days today was great! Early in the morning we got to go to the fore reef which was a little intimidating at first but also super cool! There we got to see a green turtle at the bottom and many, many sea walnuts (which were beyond adorable.) I am so glad we visited although we were only able to stay for a short while due to the weather conditions of the atoll at this time of the year. Even though I loved the experience I will say one thing: I am so grateful I decided to take Dramamine during breakfast. I think I would have felt seasick if I had decided to tough it out!

After we got back to Glover’s we all did a group clean-up of the beach. Together we picked up around 65kg of trash; I’m pretty proud of us! In the process, we also collected data on how much of the trash could be disposed of here at Glover’s and how much would have to be shipped to the mainland to be disposed of. Yet, perhaps the coolest part of our findings is that different areas of the island allow for different efficiency in collecting said trash, therefore if there is limited man power, we found that there are certain areas were effort should be a priority! While cleaning the coast, one member of our team found something that kind of shocked us all:

We are still unsure of how this level of preservation happened but it is so pristine that we were able to identify it as a type of box fish. During this trip I had heard about box fish, yet I didn’t know too much about them as they are omnivores and therefore not part of my taxa, piscivorous fish. Yet, seeing this little guy prompted me to learn a lot more about these fish, and honestly they are really cool!

Making today even better, before dinner we saw a hermit crab switch shells; I thought I would never get to see this, but this trip truly is full of surprises at every turn!

Dramamine For The Win

Leave a comment

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!

Drop off and Sea Sick (13/06/22)

Leave a comment

Another early and eventful morning. After breakfast we went out on the boat to the fore reef, just outside the coral circle of the atoll. Once we got outside the reef the waters got choppy and I got seasick a little bit, I thought once I got in the water I would feel better but I still felt sick whenever I looked up out of the water. I was perfectly happy to just lie in the water and stare down below and get pushed around by the waves. Wherever we were was at least 60 feet deep I think, but it felt way deeper. One of our water safety officers free dove all the way almost to the bottom! I had no idea that was even possible for someone to do, but we looked down and he was just swimming along the bottom below us. We saw lots of fish, but a little too deep to get a good look, and even a sea turtle way below us. We swam over to the drop off, like in finding nemo, you suddenly can’t see the bottom of the water anymore and it just drops into deep blue and then black, maybe it only goes a little bit deeper, maybe it goes miles deep, you just can’t tell or see anything past the darkness. Weirdly instead of being scared I was just more curious then anything. My first lab research experience was with hydrothermal vents and those extremophilic organisms around them, so most of my first marine knowledge was of the deep sea instead of coral reefs. I would love to someday get SCUBA certified and dive right down to the bottom to just see what’s there past what I can see from the top. And someday I’m going to go in a submarine to the bottom of the ocean if I can, I want to see everything down there, it’ll be like stepping into a completely new world.

I got pretty seasick on the way back, luckily I kept my breakfast because it’s a shame to lose a good meal, and took a short nap on the dock to get my bearings. After lunch we put together a beach cleanup activity! We managed to collect about 64 kg of trash across the island and sort it out for disposal. Highlights include:

a complete fish skeleton (not trash, just cool).

A full tube of mascara

A tiny plastic sheep

A bottle of bright blue dye that turned everything else blue

A bottle of yellow smelly liquid (pee? I really hope not)

Several baby flip-flops (why do they need shoes, they can’t even walk)

A single Balenciaga slide

and lots and lots of plastic bottles.

There was plenty more trash but our bags were overflowing and we can only carry so much. It’s really sad how much there is on what’s supposed to be a conservation site, just washing up from other islands and everywhere else in the world the currents take it.

Before dinner Nate handed out some of the shells he collected to the local hermit crabs. One of them actually accepted it, and began to examine it closely, preparing for a move. We stood in a circle around it, completely frozen so we wouldn’t scare it and watched and cheered when it moved shells into a nice new shell that was a better shape and size.

The crab was treated to some coconut, because moving is stressful.

And the coconut was quickly swarmed by the other crabs, hopefully our friend got plenty to eat before it got crowded!

Day 6 – Visiting the forereef and cleaning up the beach

Leave a comment

We started of today with a trip to the forereef, the area right outside the reef crest where the reef slopes off to deeper waters with stronger waves! Even though I took a Dramamine, I was thoroughly nauseous by the end of our trip. The ship was rocking on large waves, and even after we got out and started snorkeling we were being carried up and down on the large swells. (Here is a pic of us trying to get off the boat!)

Me on the forereef!

Although I was nauseous, it was still a really cool experience to see the deep reef areas. At one point we were swimming in a cloud of comb jellies (don’t worry, they don’t sting!). I also got some good pictures of people diving down, although none of us could go as deep as our guide Adrian (he free dived about 100 feet while we were there!). Deep below, I was able to see the bipinnate sea plume definitively for the first time! This soft coral lives 12-50 meters deep, so this was the first time I was able to see it. I couldn’t snap a good picture, as the water was too cloudy and it was pretty far away.

I was happy to be back on solid ground this afternoon, even though we spent it picking up trash! There was a ton of shoes, plastic water bottles, and other unknown or random debris. We picked up a total of 65 kg of trash, but we barley made a dent in everything that washes up here. Because of the currents from the Gulf of Honduras Gyre, trash is regularly washed from Honduras and other areas onto the Middle Caye of Glovers Reef. We were able to see firsthand all of the single use plastics in the ocean, and it certainly made me want to do a better job not using these!

We also got to see a hermit crab change shells today! We had watched a video of this yesterday, so it was especially cool to witness it in person!

After dinner, we had a great conversation with one of our guides, Ruth. She told us all about the history, climate, culture and geography of the different areas of Belize. She also told us about Belize’s relationship to the neighboring countries of Mexico and Guatemala. From this conversation alone, it is clear that Belize is a very unique place with a ton of different cultures and peoples, in a very small place (about the size of Massachusetts!).

Excited for our last day on the reef tomorrow!

I got really scared by an eel (Day 5)

Leave a comment

Hi all, it’s Faith with Day 5 updates from the 2022 Belize trip!!!

DISCLAIMER: I just wrote this whole blog, and then the draft didn’t save, so here is an abridged version of what got deleted since we wake up at 6am and its almost 11 and I’m really tired 🙂

Today we woke up and continued collecting data to answer our research question. We did two snorkels on MPA reefs ( we called them MPA reefs 1 and 2, boring I know). These reefs had more cover than the non-mpa protected areas; however, they also had a lot of algae growth. Because these reefs were deeper and the tide was calmer, it was easier to measure the % live and dead coral. We also were way more successful at catching urchins. We caught about 113 total with the majority being E. viridis. However, we also saw 3 pencil slate urchins E. tribuloides, a west indian sea egg Tripneustes ventricosus (We had a bond. He latched onto me with his tube feet and held on for dear life, so I named him Fuzzy), and a super special live Clypeaster rosaceus sea biscuit. (We usually find them dead so we got very excited).  Lastly, but not least the Marine sea offcicers found some brittle stars for me since I can’t ever find them. We saw a common spiny brittle star Ophicoma echinata and a O. cinera, a banded brittle star. They were both found under rocks and coral. We only found one Diadema antillarium today and he was under some coral. We did see a nice eel on this reef (pictured below) he didn’t scare me. I decided to call him Floyd.

After the boat drove us back, we watched 3 presentations on crustaceans, green algae, and climate change’s effects on coral. Then we enjoyed some relaxation before out next dive.

Our final dive of the day was at the seagrass beds and barrier reef behind our dorms. I noticed big differences between the two areas even though they were right next to each other! The seagrass beds were extremely warmer with ample algae and a greenish water color. Meanwhile, the barrier reef was freezing cold with a pretty aqua color. It had dead coral piled up the the surface,  but sea urchins and other small creatures made their homes in the rubble. I didn’t see any echinoderms in the seagrass beds, but we saw a an eel, a stingray, 3 lionfish, 3 lobster, a white anemone, spaghetti worms (which are very fun to mess with), and a pufferfish. The pufferish and eel scared the living daylight out of me because I found them by being directly above them (which made them very upset). The eel snapped at me, but the pufferfish just stayed in place. It was scary… I named the scary eel Jade, and he has no picture.

We came back to watch 2 presentations: 1 by the coast guard and 1 by the island manager. I learned lots of interesting facts about how they keep the island “human-free.” But the most interesting fact to tell all of you is that I’m too short to join the Belizean coast guard. You have to be 5’3″ to apply as a girl and 5’5″ to apply as a guy!!!

Till tomorrow!

Day 5: More Taxa Sightings & Reef Conservation

Leave a comment

In the morning, we traveled by boat to more marine protected areas to continue our coral health research project and conduct more sea urchin gathering/counting (I discovered that it is very fun to hold sea urchins and not scary at all :D).  We also caught our second lionfish of the day! Yay!

I also noticed a beautiful and healthy branching fire coral (millepora alcicornis). It dawned on me that despite a few stag horn corals in the area that it was one of the only branching hard coral left healthy on this reef. I could see fish and sea urchins all around it! It’s so important to our coral reef ecosystem!

I also saw my first star horse-shoe worm (pomatostegus stellatus)! It was bright orange and very sensitive to my water movement, but I finally managed to get a picture! You can tell it’s a star horseshoe worm by it’s U-shaped crown radiole, but it’s hard to see in this picture.

Below is another cool Christmas tree worm!

Later when snorkeling just off of Glover’s Atoll for our optional snorkel, I saw a pufferfish (pictured below) and a stingray with my snorkel buddy Faith. I also spotted a lionfish and alerted the group, but unfortunately we could not catch this invasive species.

I also saw some a new species of worm called spaghetti worms (eupolymnia crassicornis)! They usually live in holes in the sand or in coral and they have long (< 18 inches) thin noodle-like tentacles which help them to catch food! I was surprised to see so many since they usually live on or under the sand which makes them hard to see. If you lightly touch their tentacles it will retract which is so cool to see. I love annelids.

Later that night, we had a guest lecture from the manager of Glover’s Research Station, Rafael. He told us that this was one of the only places in the Caribbean that is dedicated to preserving pristine reefs. There is not commercial fishing in this area, and fishermen willing to break this rule face these thousands of dollars in fines- some can even face jail time. If a large amount of fish that is illegally caught and dead, all the fish will eventually be donated to humanitarian nonprofits such as orphanages. There has only been 4 infractions in 2022 so far. Three people are stationed on Glover’s Atoll which include the manager, ranger, and marine biologist and these people enforce the laws. Since there is limited staff, some times the  Coast Guard will also assist when there is trouble. The Glover’s Reef Staff has maintained good relations with the local fishermen and some of these fishermen will report illegal fishing that they see.  Rafael told us he saw a shift of thinking towards sustainable fishing for the local people as although fishing is a necessity for providing for their families they also want to preserve their reefs. Glover’s Reef Research Station has assisted the Wild Life Conservation Society in many surveys such as:  turtle egg surveys, lobster surveys, stony coral tissue loss disease surveys, and conch surveys.

It’s very cool to see these conservation efforts and I hope I can contribute in any small way! Peace and love from Belize.
