Research Assistant, University of Miami-RSMAS, Dept. of Marine Biology and Ecology
Bio: Hello! My name is Emma Pontes, and I am a recent graduate of the University of Miami Master’s of Professional Science program. I studied Marine Biology and Ecology, with a focus on Tropical Marine Ecosystems at UM’s Rosenstiel School of Marine and Atmospheric Science (RSMAS). I also received my Bachelor’s degree from the same institution in May 2015. As an undergraduate student, I double majored in Marine Science and Biology, with a minor in Chemistry. Currently, I hold a full-time position as a Research Assistant in Dr. Chris Langdon’s Ocean Acidification Laboratory at RSMAS. Our research is focused on studying the effects of ocean acidification and climate change on coral reef ecosystems. As part of my Research Assistant position, my Dr. Langdon sends me on research cruises such as GOMECC-3 to collect dissolved oxygen data that can be compared to historic data sets. I have been on one other long-term research cruise, P18 GO-SHIP, which set sail on the Ronald H. Brown in December 2016 with a course to Antarctica. After spending more than 10 days in the Antarctic Circle, I am ready for some warm weather around the Gulf of Mexico!
What I’m doing on this cruise: My job on GOMECC-3 is to analyze water samples for their dissolved oxygen concentration. I will be running titrations to determine the oxygen concentration of water samples using a standardized procedure called Winkler Titration. Oxygen is an important indicator of climate change effects, and its change over time will give insight to how ocean chemistry is changing. We will be revisiting data sets from previous cruises to compare historic and current values of oxygen concentration in the ocean.
