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

Fire and Burns

Hey guys! It’s Michiel again : )

We started this morning with breakfast (big surprise) before going out to collect more data for the research question we started on yesterday. The first reef we went to was in the Marine Protected Area, and it was deeper than the reef we went to yesterday. It also had a lot of sea grass, algae, and dead coral. Ava and I laid out our transects and quadrats and counted a lot of coral all over the reef. While we were doing this, Ava took a picture of me counting squares in my quadrat, and I’m sharing it here (once again, thank you Ava)! After collecting this data, we were sent out to collect sea urchins. I found a lot in coral crevices, but these were really difficult to pull off of the coral. However, that did not deter me from trying. I ended up getting two sea urchins, but as I tried to get another one, the crevice my hand was in had fire coral. Thankfully, only my pinky brushed up against it, but I definitely had a burning sensation there for about an hour. It was worth it, though, because we ended up collecting 52 sea urchins! Additionally, I believe I saw a male Bluelip Parrotfish (Cryptotomus roseus), and I definitely saw more Ocean Surgeonfish (Acanthurus bahianus) and Blue Chromis (Chromis cyanea). Scott also took a video with a damselfish in it that kept making its signature popping sound to show aggression. Damselfish are aggressive toward other fish that come near their algal gardens because they don’t want those fish to eat the algae they’ve worked so hard to cultivate.

Chromis cyanea

After this, we went to another reef in the Marine Protected Area. This reef was much shallower than the other one; it was about as shallow as the reef we went to yesterday. We did manage to collect our data better in this reef than the one from yesterday, though, because the waves were not nearly as strong as yesterday’s. However, Ava and I were very scared we would touch some fire sponge because it was absolutely all over the reef and we were swimming only inches above it. After collecting our data, we were out on the hunt for sea urchins once again. I collected two sea urchins again, but I learned my mistake from last time and only tried to collect them from beneath coral rubble instead of from inside coral crevices. In total, we collected 56 sea urchins from this area!

On our way back to the island, I noticed that I got a sunburn on my hands, so I’m really excited for the tan I’m about to get that starts at my fingers and ends at my wrists. On the island, we had lunch and were given the option to participate in an optional snorkel activity. I opted out of the activity because I was so drained from this morning, but I spent the afternoon working on my field notebook, messaging some friends, and reading my book. I’m very glad I chose to rest.

At the end of the break, we had dinner, were given presentations on the Belize Fisheries Department and the Belize Coast Guard. Overall, today began with lots of work and ended with a well-deserved break. I’m excited to go out onto the reef again tomorrow to collect more data and see more fish!

See y’all next time!

So Many Fish!

Hey guys! It’s Michiel again; I’m sure you all missed me : )

This morning started the same as every other morning here. I woke up, got ready, and joined the others for breakfast in the dining hall by 7. After breakfast, everyone in the class put on their snorkeling gear and went out into a new area of the water that’s behind the dining hall. It was full of sea grass and very shallow, but our goal was to find as many interesting species as we could and put them in a bucket. Some notable finds were a lobster, Diadema antillarum (a sea urchin with an interesting history), a sea anemone, and several crabs. In regards to herbivorous fish, though, we caught a Cocoa Damselfish (Stegastes variabilis), and a Bicolor Damselfish (Stegastes partitus). These fish are actually very territorial, so we saw them chasing and trying to bite one another in the bag. Once we laid out all of the species we caught in the wet lab, every person presented on the species caught within their taxa. We passed around lots of algae and talked a lot about different corals; it was so much fun!

After this, we took a break for lunch before going out on a boat in our snorkeling gear to work on a new research question we had come up with earlier in the day. We are trying to identify the correlation between sea urchin prevalence in a reef and the percentage of dead coral in the reef, and we want to see how this changes between Marine Protected Areas and other areas. We went to a reef that wasn’t in an MPA and tried to measure the percentage of dead coral in the area we were looking at using transects and quadrats. However, the waves were really strong and the reef was shallow, so Ava and I kept getting pushed into coral. After collecting this set of data, everyone collected sea urchins for 10 minutes, and we actually found 18 of them!

With our urchins and data collected, we left this reef and went to a new reef that was in an MPA. However, since the wave conditions were so harsh, we just snorkeled instead of collecting data. This reef was really nice. It had a bunch of fish diversity. I had a lot of people coming up to me asking about fish they saw (they mostly saw Yellowtail Damselfish and Blue Tangs). Unfortunately, I saw neither of these, but I did see a Blue Chromis (Chromis cyanea), which is beautiful, and some Threespot Damselfish (Stegastes planifrons). These kept staying very close to the coral, hiding in the crevices as I approached. They tend to do this because they’re pretty small, so they’re great prey for larger fish and are therefore more likely to hide when approached by something larger than them. We also saw a huge lionfish that Scott speared and took with us back to the island! Hopefully we will be feasting on lionfish ceviche tomorrow.

That was most of my day! We had some presentations in the evening that were very interesting (as always), but now it’s time to rest in preparation for tomorrow. Have a great night, guys! (Also here are my very feeble attempts at taking pictures of some of these fish).

Day 3: The Coral Graveyard

Much like I am assuming most days on this trip will be, today was full of many new skills both in and out of the water. As a class, we seem to have graduated past simple scenic observational snorkeling and were tasked with developing and testing a research question for our afternoon snorkel. Utilizing a quadrat and a transect tape, we aimed to evaluate the prevalence of the macroalgae penicillus as we swam out away from the dock to closer waters. I must say, this was easier said than done. We thought the algae would be relatively easy to find, yet finding the marine equivalent of a green Truffula tree among a dense forest of also green seagrass did not go as smoothly as first thought. Yet, we managed to find a few, and created a poster outlining our results.

However, after lunch is when the truly exciting action took place. We went on a small walk (this time well protected from the ravenous mosquitoes) and ended up on the seaward side of the island where there is a graveyard of coral fragments. If you have seen the graveyard scene from The Lion King, it had similar vibes, yet in this case, the graveyard provided an unprecedented opportunity to look at the skeleton of stony corals. For my cards and presentations, I did a significant amount of research regarding the different stony corals of the Caribbean, yet many of the ways to tell the species apart is by the skeleton (which you would hope to not see on a healthy reef). This graveyard of coral provided the perfect opportunity to see these unique characteristics which are typically obscured by tissue. Porites divaricata, Pseudodiploria stigose, Acropora palmata and cervicornis, are just a few of the many of species that we saw and discussed. I also happened to find a piece of Eusmilia fastigiata, which was a rare and cool find.

After sadly leaving the coral graveyard, we wrapped the day up with several presentations covering Lionfish, herbivorous fish, piscivorous fish, and a fantastic yet kind of depressing presentation illustrating the future of our coral reefs. Another incredible day.

What Lies Beyond the Mangroves of Death??? (Day 2)

Hi all, it’s Faith with Day 2 updates from the Belize trip!!!

Today we woke up and hit the ground running. We had delicious banana pancakes that reminded me of the ones I make back home, and then some Black Iguanas, Ctenosaura similis, watched us prep for out first snorkel.

For our first snorkel, we saw lots of patch reefs, soft corals, hard corals, and many reef fish. From this dive, my favorite thing was the Christmas tree worms that we found burrowed in brain coral. We had lots of fun watching them pop in and out of their burrows. Our dive safety expert, Ruth, also let us hold a Queen Conch Snail!!! Some other interesting finds were pufferfish, a corallamorph, a yellow stingray, and lionfish. I was disappointed that I didn’t see my taxa, but that disappointment dissipated when we started our next activity– quadrats.

What is a quadrat you ask? Well, it is a “handy tool you can use for many things.” I’m not actually sure what it does yet, but it is a square PBC pipe tool with a grid-square net inside. And you’ve got to “belieze” the hype that comes with constructing your own quadrat. It truly makes you a marine biologist.

After lunch, we grabbed our clipboards and “willingly”  (100% not persuaded by the kids) voted to go into the M.O.D.  With our clipboards and fins in hand, all 18 of us RAN through seemingly endless mangroves with swarms and swarms and swarms of mosquitos to our watery safehaven. I got lucky and made it through with maybe 10 or so bites, but many have it much, much worse.

But the buggy adventure was worth it. My partner Maegan and I  attempted to complete the scavenger hunt on our clipboards, but we got sidetracked searching for our taxa. Again, I was distraught over the lack of echinoderms until I saw a broken sea biscuit (Genus Clypeasteroida). I knew that if their were empty sea urchin skeletons, then there were live ones somewhere nearby! I ended up seeing two live Sea biscuits, but many more calcite skeletons… (there were rumors of brittle stars and donkey dung sea cucumbers but I didn’t see them). The sea biscuits were not doing too much, they were sitting on their own or under coral.

Then the time came for us to stop swimming around the reef and run through the mangroves (or so we thought). In reality, we ended up snorkeling back to the wet lab. Our dive back featured another stingray, a nurse shark, and fire sponges growing in the seagrass beds. I also found a plastic bottle with a crab inside! (Don’t worry, I recycled the bottle).

No lizards to report today except for a brown anole Anolis sagrei  and of course the previously mentioned iguanas!!! Til’ tomorrow!!!

Quote(s) of the day:

“Vote mangroves and we won’t send the crabs into your rooms tonight”

*Pointing at a dead Sea Biscuit* “It’s a fossilized sea star!!!”

Day 2: Snorkeling and the MOD

After a good nights rest, we rose early in the morning to start off our day snorkeling at Glover’s Reef! We had all our gear and were ready to start our first snorkeling adventure by 8:05 am which was a record breaking time according to our professors. I was amazed by the biodiversity of marine life on our snorkel! I recorded hard corals, soft corals, damsel fish, puffer fish, parrot fish, lion fish, lobster, and many more interesting species! Nyala and Caio pointed out my first annelid- Christmas tree worms! These worms bore into coral and have a spiral-shaped crown that are always seen in pairs of two (even though it is actually one worm). They can come in all shapes and colors and will retract back into the coral as if they were never present if they sense water movement of a big fish or larger creature, like us. (sorry for the poor camera quality!)

Hydrozoa are hard to locate on the reef but I spotted some fire coral today! Fire coral is an interesting creature because it is an athecate hydroid that behaves like a reef-building coral.

We also built quadrates which is a tool used by field biologists to help us measure and collect data!

Later for our second snorkel of the day we were given two choices- the safe choice of the adventurous choice. The safe choice was to snorkel in the reef we had just been at while the adventurous choice required us to walk through the MOD… Mangroves of Death that had swarms of mosquitos that would bite you even as you were running. We of course chose the adventurous path, and the misquotes were terrible but the marine organisms we saw at this next location made it worth it. We saw many fish as well as a nerf shark and sting ray. I also got the chance to observe two more annelid species. The magnificent feather duster worm was a multicolored worm (red and white) with large feather-like bristles shaped like- you guessed it- a feather duster. This worm will also retreat into the coral if there is water movement. I think I also spotted a spaghetti worm’s long white, thin tentacles under the coral, but it was difficult to tell.

Afterwards we listened to some presentations that helped us learn more about different reef creatures and reflect on the journey ahead. More to come! 😉

First Reef Day!

Hey y’all, It’s Michiel again : )

Today was so much fun! This morning was absolutely beautiful and I loved looking out over the island during breakfast. Just after breakfast, we saw an iguana. It was very pretty and we kept seeing iguanas (or perhaps the same iguana) throughout the day.

After breakfast, we put on our snorkel gear and dove off the dock. The tropical waters were very inviting with how warm they were. We saw huge schools of tiny fish which we could not identify. Once my partner (Ava) and I made it to the patch reefs, we could not get enough of our taxonomic groups. They were telling me all about soft corals and I returned the favor by offering them  facts about herbivorous fish. In this reef, I saw a lot of herbivorous fish, but I didn’t have my taxon ID sheet so I was only able to identify a few. We definitely saw a lot of Threespot Damselfish (Stegastes planifrons) and Cocoa Damselfish (Stegastes variabilis), and I believe we may have seen an Ocean Surgeonfish (Acanthurus bahianus). I noticed that it’s really hard to get good pictures of a lot of these fish because they hide as you approach, so I stayed a good distance from them and zoomed my camera in as much as I could.

Once we got into the water, we went to the wet lab to make quadrats and set up a scavenger hunt. Soon after this, we decided to explore the reef near a different part of the island, but to access that area we had to go through the Mangroves of Death (MOD), which were filled with mosquitos that chased us and bit through our lycra dive skins as we ran through the forest. Finally finding safe haven within the water, Ava and I went off again to look at more soft corals and herbivorous fish. While there, I saw many Sergeant Majors (Abudefduf saxatilis) and Beaugregories (Stegastes leucostictus). We also saw a lot of competition between corals, and we saw two stingrays! Ava and I were very grateful that we had decided to swim over the seagrass instead of walk through it when we saw those.

After this second reef excursion, we had wonderful presentations given by Rusty, Ava, Maegan, Phoenix, and Michael who presented on hard corals, soft corals, coral reef framework, ctenophores and jellyfish, and sponges respectively. Now, the day is over and I am posting this blog before getting some rest.

Also, I’ve included a group photo of some of other TFBs and I hanging out in the wet lab! See you guys soon!

Crab: 1 Liliana: 0

It’s day 2 on Glover’s and our first day in the water! We had a super early (in my opinion) start, everyone woke up around 6:30 and we all geared up and headed to breakfast at 7. After some delicious banana pancakes we got into the water for the first time and went to a patch reef a little ways off. It was a pretty calm swim through a lot of sea grass and then before we knew it we were at the reef! It was incredible and I wish I had photos to add here but I didn’t bring my camera on the first swim, hopefully someone else here will have photos for you to see! We saw so many corals and fish, and such a wide variety of organisms all over the place. Everywhere you looked there was something new to see. We even saw a small lionfish sitting on the reef, which is not ideal for invasive reef species control, but still interesting to see one out in the wild in real life! The first swim was a good one for my taxon group, crustaceans; we saw a Caribbean spiny lobster hiding in a hole underneath some coral, another organism I have been hoping to see in real life. After about an hour in the water we went out for a break and some land prep for tomorrow before lunch. Around this time I was outside with the two kids who had collected a bunch of crabs in coconut shells. They showed me one smaller crab and despite their warnings that he was (understandably) angry, I tried to pick it up to get a better look. Alas, the crab outsmarted me and got a good chunk of my finger in his claw, luckily it didn’t draw blood, just a long scrape and my hurt pride. Clearly my crab catching skills are a little rusty, but there are plenty of other crabs around that are hopefully a little friendlier.

We went back in the water after lunch, but not before a quick jog through the mangroves of death. While dramatic sounding, it’s pretty much a trail through the island that goes along the mangroves, and is absolutely filled with mosquitos, it felt like they were completely covering us until we all sprinted into the water and hid under the surface for them to go away. Once we got through that we shuffled our way through a bunch of sea grass until we got to a sandy area with lots of patch reefs, and we went swimming through looking for behaviors and organisms as part of a scavenger hunt. This area was less protected by the island from waves so we were pushed from side to side and through the reef and pulled around. My handwriting is already terrible, but with the waves pushing my arms and clipboard around I don’t think any of my notes are legible. Unfortunately these waves also pushed me up against the coral, and soon after I swam further away I realized that the part of my hand that had gotten smacked into the coral was turning red, and felt a little like it was burning. I discovered that I had the misfortune of bumping into a fire coral, named that probably because it hurts when you touch it. Coral: 1 Liliana: 0

However at the end of the day we went through our first round of taxon presentations and lectures, and by then my finger didn’t hurt from the crab and my hand wasn’t burning from the coral, and despite all the bug bites, I can’t wait to do it again tomorrow!

Snorkel Day + Sea Cucumbers

Hi everyone! What a day! This morning we learned about reef zonation and took a boat ride outside the calm waters of the reef crest and into the higher energy fore reef to explore the organisms (in particular the coral) outside the atoll. There I spied some small reef urchins (Echinometra viridis) buried in the crevices among the large coral. Amazingly, we also got to see a couple larger marine creatures out in the fore reef. We all watched in wonder as an enormous spotted eagle ray glided along the benthos and a nurse shark navigated its way through the coral.

Our afternoon time in the water was spent on the shallow back reef much closer to the island. This area was just as interesting as the fore reef to me, and I got to hold several donkey dung sea cucumbers (Holothuria mexicana) that were about a foot long and on the sand among the sea grass on the edges of coral. The back reef was also neat because I got to swim alongside many schools of fish. While we were at the back reef, we also managed to spear some lionfish, an invasive species from the Indo-Pacific that consume many native species of fish, to study and make ceviche out of later on. I can’t wait to see how that will go! 🙂
