During summer 2020, I worked at Padre Island National Seashore examining marine debris ingestion by sea turtles in the Gulf of Mexico. To address this question and quantify ingestion, I extracted marine debris from the gastrointestinal tracts of 300 green sea turtles from 2007-2009 and 2019. Then, with assistance, I individually measured each piece of marine debris from these turtles and additionally measured previously dried debris from 400 green and Kemp's ridley sea turtles from the 1990s. Using this data, I explored temporal and spatial patterns in marine debris ingestion based on species and size. Results from this study will provide insight on whether the incidence rates of marine debris ingestion by sea turtles in the western Gulf of Mexico has changed over the last two decades. This position was supervised through collaboration of the National Park Service and the Ecological Society of America.
