Sea turtles live in many of the world’s oceans and thus, researchers around the world study many different aspects of sea turtle biology. We have designed this app so that researchers can log turtle capture, nesting, or product data and location. By mapping these records, researchers can keep track of data collection locations, capture history, and monitor conservation efforts in areas of interest. Researchers have traditionally used paper data sheets to collect sea turtle information. However, depending on the projects being conducted, there may be several data sheets for one project. These data sheets may be degraded by rain, humidity, or fire. It is our hope that sea turtle researchers will utilize RASTR to help consolidate and supplement physical data sheets, and digitally store their data on a cloud-based system that is not subject to the same degradative effects. Thank you for using RASTR to aid in your data collection. We hope that it will be a useful and enjoyable experience.
