As marine resource managers continue to adopt ecosystem-based approaches, there is a growing need to acquire reliable spatial information on species distributions. This project will develop and apply advanced species distribution models (SDMs) while simultaneously testing new monitoring methods for coastal waters in southern California. The models will couple highly resolved maps with in situ survey data of marine species. The surveys will be conducted through both traditional SCUBA and through newly designed stereo-video drop cameras to evaluate the level of correspondence between the two methods as well as cost effectiveness and the potential for citizen science application. Results will be shared through peer-reviewed scientific publications and the Ocean Science Trust website.
