The San Diego Shelf Collection contains invertebrate specimens that have been collected over last 20 years by the City of San Diego's Wastewater Department for environmental monitoring projects. These specimens were collected from several sites arrayed at various distances from the Point Loma and South Bay Ocean Outfalls, mainly from 30 to 90 m depth. Environmental meta data is also available for each collection site. This time series collection has high value for future studies of environmental impacts and biodiversity. The collection was generously donated by the City's Wastewater Department and now in the process of being sorted and cataloged.
