First of all, our stuff arrived! After a few more phone calls to the customs office, everything went smoothly and all of our gear was delivered on Tuesday—not too shabby, really!

The next site on our list was called Bique, an intertidal area that has some freshwater input. Many sites on the Pacific side of Panama have large stretches of beach that are uncovered at low tide but completely underwater at high tide. So we are sampling at low tide, when the oysters on the rocks are exposed and much more easily accessible.

At this site, we decided to check out the mangroves first to see if there were any oysters attached to their roots that we could sample. While we found some, they were pretty difficult to get off. Our collaborator, Mark Torchin, thought it safest to strap himself to a mangrove, as the banks were made of soft mud and it is all too easy to fall into the stream. Additional acrobatics, such as scaling mangroves, navigating through root mazes, and climbing back up off the muddy banks, were required to get these oysters, but we prevailed and were able to walk away with about 30 individual oysters.

We then headed back out to scrape oysters off the rocks and found two different species, Saccostrea palmula and a species of Crassostrea, in the rocky intertidal zone. As our supplies had arrived, I now had the equipment necessary to obtain and filter water samples as well, so I walked out along the rocks to get a liter of surface water from the incoming tide. Part of my fellowship research involves comparing the different kinds of parasites in the water column to what is infecting and being filtered by the oysters. Water sampling is just one way of obtaining a more complete picture of parasite diversity in the different sites that we are sampling.

I would love to be able to say that I am a world traveler with loads of experience visiting other countries, but that would be far from the truth. Unfortunately for me, my passport has only a few stamps. (Two to be precise, as it wasn’t stamped for walking across the border into Mexico or crossing the border to have dinner in Canada.) So traveling to Panama to collect oysters has expanded my horizons in more ways than one!

In Panama, Kristy and I are working with Mark Torchin and Carmen Schloeder, scientists at the Smithsonian Tropical Research Institute in Panama. Our first sampling site was about a five-minute drive from the Smithsonian’s Naos Laboratory, which sits just outside Panama City on the Pacific Ocean.

I arrived in Panama City at 10 p.m. Saturday night, and as the plane started its descent into the city, my eyes widened at the sight of the city lights. It looked as if Clark Griswold had bedecked the entire city with Christmas lights! Tall buildings flashed extravagant multicolored light shows. I started getting that flutter of excitement in my stomach. I was about to spend two amazing weeks in Panama doing the science that I love!

I got through immigration and customs without incident despite my inability to speak Spanish well (yo hablo muy poco español). At any rate, I found my shuttle driver holding a sign with my name on it, so I felt pretty special as we walked out into hot and humid Panama.

My driver, Victor, showed me wonderful Panamanian hospitality. Luckily he spoke English very well and gave me a tour of the city on our way to the hotel. He recommended some places for us to visit if we had free time, and we talked about his experiences scuba diving in the Caribbean.

I arrived safe and sound at the hotel, where I managed to wake Katrina, who was already fast asleep with visions of sugar plums dancing through her head as I fumbled with my suitcases. I climbed into bed as well shortly thereafter and dreamt of Panamanian oysters dancing in my head…

Buenas noches!
