About Us


In 1997, we began a beach survey program using trained volunteers to survey beached marine birds and mammals monthly at selected sections of beaches throughout the Monterey Bay area. The program is a collaborative project between Moss Landing Marine Laboratories (MLML) the Monterey Bay National Marine Sanctuary (MBNMS), and other state and research institutions including the California Department of Fish and Wildlife (CDFW), US Geological Survey (USGS), and US Fish and Wildlife Service (USFWS) with the specific goal of using deposition of beach cast carcasses as an index of the health of the sanctuary.
As of May 2019, we have more than active 100 volunteers that survey beaches from Santa Cruz to LA county.  This program has been greatly successful, providing data for a number of scientific papers, contributing to the conservation of sanctuary resources, identifying and quantifying oiled wildlife, and a great many more accomplishments.

  • Obtain baseline information on rates of deposition of beachcast birds and mammals:

    Trained volunteers identify and quantify all dead birds and mammals on sandy beaches along the central California coastline, between San Mateo/Santa Cruz County line and Santa Barbara. Beach surveys are conducted monthly at most locations and 2 times per month at selected beaches. These data provide a baseline for deposition rates along the CA coast during all seasons.

  • Assess causes of seabird and marine mammal mortality:

    Volunteers note the cause of death (e.g. presence of oil or entanglement in fishing line) for each organism found. When possible, fresh specimens are collected for post-mortem examination by a veterinary pathologist from CDFW.

  • Assess abundance of tar balls on beaches:

    The abundance of tar balls on beaches is determined and used as an indicator of amount of chronic or low-level oil deposition. In the case of large deposition of oil, volunteers are trained in the proper procedure for sample collection and storage. These samples will be used to determine the source of the oil (e.g. natural seeps or vessel traffic).

  • Assist resource management agencies in early detection of mortality events, both natural and anthropogenic:

    Beach COMBERS consist of scientists, resource managers, and citizens that have formed a well-connected group. This allows the quick accumulation of information about the resources of California into a centralized location, and the rapid dissemination of information to the management and enforcement agencies (e.g., MBNMS, CDFW, NMFS).

  • Build a network of interacting citizens, scientists, and resource managers:

    Frequent interactions in training sessions, enrichment events, and local meetings, provide a mechanism for scientists, citizens, and managers in the Beach COMBERS program to transfer information and awareness of resource management and policy.

  • Disseminate information to the public and educational institutions:

    Data from the Beach COMBERS program will be provided to the public and schools via web pages, a CeNCOOS data portal, scientific meetings, teacher education classes (MLML), and interactions with the public on the beaches.
