Quadrats + Coral Graveyard

Leave a comment

I felt like such a tropical field biologist today (with training wheels of course). We started off the day with a land activity using transects and the quadrats that we made yesterday. Liliana and I got some practice using the gear and with the methodology by gathering data to characterize what percentage of the measured area had evidence of hermit crab movement through the sand. Here is a photo! (The square is the quadrat, the line is the transect, and the orange rectangle is a very fancy dive clipboard)

Then, all of the TFBs put our heads together and came up with a question to test with this procedure out in the seagrass beds. We chose to investigate how the density of penicillus (a green algae) changes with the distance from the shore. We decided on a uniform methodology and got to work! I saw a lot of warty corallimorphs and great Caribbean sea anemones in the seagrass beds! After we collected our data in the water, we came back to the wet lab and compiled our data. We all made a poster that reflected the entire experiment, including results, discussion, and figures (one of which is a taped-on penicillus in a quadrat heart).

While working in the wet lab, I ate some freshly husked coconut as a snack!

Later in the day, we went to what Adrienne called the “coral graveyard,” and which she also described as “the most amazing place on the planet.” It really was amazing! The field of coral skeleton rubble was extremely well-preserved, and we were able to identify a lot of the species! One thing that I was particularly excited about was seeing and correctly identifying Montastraea cavernosa fragments. I took Adrienne’s coral reef ecosystems class, and my semester-long research proposal centered around this coral. It was so gratifying to get to hold a piece of its skeleton framework!

Besides the few sightings I got in during our penicillus data collection, I didn’t have a lot of time or opportunities to focus on my taxonomic group today. However, I am now so much better at recognizing great Caribbean anemones and warty corallimorphs!

Although my collection of mosquito bites has grown to be rather impressive, I can’t wait to get more if that means I can have more days like this!

First Reef Day <3

Leave a comment

The McKenna that is writing this post is a completely different person than the McKenna that wrote the previous blogs. Today, I saw coral reefs with my very own eyes, and it was such a life-changing experience!

The day started early with breakfast at 7:00 am. We wasted no time getting into the water, and we swam to path reefs close by the Glover’s dock. I was surprised by how much sediments can make snorkeling an issue; one kick downward with your fin and all of the scenery around you is made barely visible. Needless to say, I quickly learned to stay on my stomach. At the patch reefs, I saw so many amazing things, notably a baby lionfish and a pufferfish. On the way back, I saw a Great Caribbean anemone in a bed of seagrass! (Please forgive that this is a photo taken of a digital picture)

After getting back, we made reef supplies for future endeavors, including an expertly-woven quadrant and a top-of-the-line snorkel clipboard with waterproof paper!

After lunch, we suited back up and sprinted (I’m not kidding, we actually sprinted there to avoid the swarm of mosquitos) to explore the mangrove of death (oooo aaahh). We brought our clipboards with us to do a scavenger hunt! Liliana and I were buddies, and we found lots of cool things, like a sea cucumber and a Christmas tree worm. We decided to swim back because the mosquitos were that bad, and that is when I spotted a warty corallimorph! This is usually a solitary organism, so it was all by itself. (Again, photo of a photo)

The mangrove snorkel was amazing! Afterward, we ate dinner and gave presentations.

Today was incredible. I am so excited for the upcoming reef days to explore more! Another night of needed rest awaits me. A TFB always needs their beauty sleep 🙂

Day 1: Exciting Travels!

Leave a comment

After a day of travels, I am filled with excitement, but I am also officially exhausted. Today was a long day of here-to-there (from car, to shuttle, to airplane, to van, to boat), but every leg of the journey was enjoyable!

Once in Belize, I noticed how humid it is, and that is because we are in the beginning of the wet season. There are palm trees galore, and the buildings are such vibrant colors! We stopped at a shop after leaving the airport, and I got some Belizean snacks that I can’t wait to try. The boat ride to Glover’s Reef was longer than expected but a beauty to behold. I saw so many different shades of blue! My favorite part of the ride was crossing the barrier reef. As we approached the barrier reef, we could see the whites of the waves crashing into the reef crest. Our boat was navigated through a channel in the reef. And on that channel was a small island packed with tourists. I attached a photo I took of the island, like a little paradise out at sea!

The Glover’s Research Station is amazing! The facilities are just what we need, and all of the people here are so friendly! Hermit crabs and other crabs walk around the island like squirrels on Rice campus, so I’ll have to remember to watch where I step.

Tomorrow, we start our morning at 6:30 and have our first day out on the reef! I am completely new to snorkeling, so I am excited to get my feet wet (pun intended). I will keep my eyes peeled for any corallimorphs, zoanthids, or anemones!

For now, I am going to get as much sleep as I can to prepare for the busy week ahead out on the reef!

First Blog: Pre-Departure

Leave a comment

Hello everyone! I’m McKenna, and I can’t wait to leave for Belize tomorrow! I’ve done very little traveling in my life, so I have been feeling some nerves for the past few days. However, I expect all of my worries to subside once the trip has started and I am overcome with excitement!

The preparations for this trip have filled my time over the past few weeks. One practical and slightly embarrassing preparation was breaking in my rubber boots. More than once, I went to the gym and walked on a treadmill in my boots and hiking socks for an hour. I’m so glad I put my dignity aside and dealt with the blisters beforehand rather than in the field. Additionally, the assignments and readings for this class have prepared me with background knowledge about Belizean reefs, tropical forests, and cultural history. Through the upcoming trip, I hope to expand on this foundation through in-the-field studies and build a more in-depth understanding of the ecosystems and landmarks we visit. I look forward to treating each day as a day-in-the-life experience as a tropical field biologist, and I hope this trip will help to enlighten me of my interests and passions to possibly put toward my future career.

As someone who finds comfort in routine, I am a bit uneasy about the plethora of unknowns that these two weeks present. However, my nervousness is outweighed by my enthusiasm to see and do things completely new to me. After having taken Dr. Correa’s lecture course on coral reefs, I am especially excited to snorkel at Glover’s Reef! And after taking Cin-Ty’s birding class, I am also excited to visit the rainforest and see and hear tropical birds! I have zero prior experience in the tropics, and my little experience with fieldwork has either been on or around the Rice campus or with Dr. Solomon in Brazos Bend State Park. Despite my little experience, I feel prepared and am more than ready to gain some real experience through BIOS 319!

In less than 24 hours, I will be on a plane headed to Belize. Here’s to my awaiting travels!
