Baseline Marine Debris Data (2015-2023) - Proposed Chumash Heritage National Marine Sanctuary

This dataset is synthesized coastline marine debris data from three existing sources and primary collected data. It covers the Central California region from Cambria to Naples for the years 2015-2023. This file contains 40 marine debris item type categories, 6 marine debris material type categories (plastic, glass, metal, cloth, paper and wood, mixed), and 7 marine debris source activity categories (personal hygiene, recreation, smoking, eating and drinking, fishing, dumping, and various). This data set is part of the broader research project conducted by students at the Bren School of Environmental Science & Management. See the research project's abstract for more information: 
California is both a major source of anthropogenic marine debris and an area particularly vulnerable to its damaging impacts. However, little is known about the quantities and impacts of marine debris in the proposed Chumash Heritage National Marine Sanctuary (CHNMS) along the central coast of California.

## Data Description & Access

This data set contains 907 rows with 73 variables. Each row is a separate marine debris coastal cleanup within the proposed Chumash Heritage National Marine Sanctuary coastline in Central California. The variables include 40 marine debris item type categories, 6 marine debris material type categories (plastic, glass, metal, cloth, paper and wood, mixed), and 7 marine debris source activity categories (personal hygiene, recreation, smoking, eating and drinking, fishing, dumping, and various).
