Boa constrictors dripped from mangrove branches |
We
encountered sharks, crocodiles, boa constrictors hanging from low branches,
stinging jellyfish, and deep holes in the mangrove peat that swallowed up our
legs and banged our shins. In a day, we could sample about 6-7 stations and
returned at night to Carrie Bow, filthy, sunburned, covered with mangrove muck
and the microbial soup that flourished in the interior ponds. After a shower, a
couple of beers, and dinner, we were refreshed and headed up to the lab to
prepare samples, write up our field notes, and analyze nutrients.
Most memorable were the encounters with
“dangerous” animals. Our first season of collecting samples at unknown grid
stations took us to an area of the eastern Twin Caye. To get to this site
required extensive bushwhacking over 1-meter high red mangrove prop roots
(i.e., roots of red mangrove trees grow have a portion growing above ground)
for several hundred meters. We ended up in a clearing with a shallow pond right
around dusk. Wooller typically led the group with PVC poles in hand and GPS
extended in his hand towards the pre-determined site.

USC postdoc Barbara Smallwood was
particularly sensitive to the ubiquitous jellyfish that inhabited the open
interior ponds. One particular voyage into the very center of Hidden Lake, a
several hundred meter wide shallow (<2 meters) interior pond was especially
disconcerting for Babs. No boats could reach Hidden Lake. We tied up our boat
to mangrove roots at the entrance of a narrow, 2 meter wide channel, then
leaped into the water and climbed into small kayaks or onto large inflatable
inner tubes. Then we paddled about 200 m with low hanging mangrove vegetation
above us towards the Lake. Once, a boa constrictor was seen draped over a
branch. Twice, I went to Hidden Lake towed via a rope tied around the waist of
a helpful colleague, Quinn Roberts (2002) and Dave Baker (2011) so that I could
collect sponges and mangrove leaves along the way. Laughter rang out in the
air. We were a noisy bunch.
Cassiopia is the species of
jellyfish that almost exclusively inhabits these waters. On sunny days they
float with their tentacles sticking up to allow the symbiotic algae in their
tissues to catch sunlight to fix carbon in photosynthesis. During rainy or
cloudy weather, they turned bell side up and rested on the sediment surface.
The afternoon we came with Babs into Hidden Lake was sunny and beautiful.
Unfortunately the jellyfish were floating in force. It did not take long for
Babs to notice that what was a mild sting for the rest of us caused a painful
rash for her. She had to jump from mangrove root to mangrove stump to avoid the
stings, screaming all along the way.
