In January, Hannah Hastings '’08 and Andrea Pain '‘08 collected seagrass from the ocean floor to study nutrient content in a dinoflagellate-rich ecosystem off the southwest coast of Puerto Rico. The seniors returned to Wesleyan and analyzed their samples for carbon, nitrogen and phosphorus levels. They discovered a high ratio of nitrogen to phosphorus compared to the normal ratio in the ocean. “"We discovered that high dinoflagellate concentrations are directly associated with elevated nitrogen to phosphorus ratios,"” Pain said during Part I of the Earth and Environmental Science Department’s Senior Seminar Research Project colloquium March 6. Part II of the…
