The oceans are of vast importance, and marine species and ecosystems are at risk. Human impacts on marine habitats are greatest in areas of high population density, including the Los Angeles metropolitan area, which is adjacent to a productive and diverse stretch of coastline. Researchers at UC Irvine are tackling many of the pressing environmental concerns that impact oceans at both local and global scales, including the effects of pollution, climate change, marine debris, invasive species, nutrient loading, and biodiversity loss. Locally, UC Irvine faculty are at the forefront of coastal ocean monitoring and are leading restoration and conservation efforts in Orange County.
