John Ross

Associate Environmental Scientist
Environmental Informatics Program

Mr. Ross received his B. S. in Biology: Concentration in Marine Biology and Limnology from San Francisco State University in 1996 and his M. A. in Biology: Concentration in Marine Biology from San Francisco State University in 2001. He performed his Master’s research on the factors influencing the depth distributions of pelagic juvenile fishes off central California. While working towards his degree, he held the positions of systems coordinator and computer operator in the clinical laboratory computer department at Alta Bates Medical Center in Berkeley, California. Mr. Ross joined the staff of SFEI in 2000 and works primarily on the Regional Monitoring Program. His interests include statistics, especially methods for the analysis of censored data.

Regional Data Center (Project)

SFEI is one of the state's Regional Data Centers that exchanges water quality data to the California Environmental Data Exchange Network (CEDEN). SFEI provides data management and visualization services to the San Francisco Bay-Delta and northern montane regions.

Contaminant Data Download and Display (CD3) (Project)

Contaminant Data Display and Download Tool or CD3  is an innovative visualization tool for accessing water quality data for the San Francisco Bay-Delta and northern montane regions. It is the primary tool for accessing and downloading the San Francisco Bay Regional Monitoring Program’s (RMP) long-term dataset and other project data stored in SFEI's Regional Data Center (RDC).

California Environmental Data Exchange Network (CEDEN) (Project)

The California Environmental Data Exchange Network (CEDEN) is a central location to find and share information about California’s surface waters, including streams, lakes, rivers, and the coastal ocean.

Completed! Legacy datasets saved from the shelves and uploaded to estuary-wide data repository (News)

SFEI worked in partnership with the Delta Conservancy to complete a two year project funded by a USEPA National Environmental Information Exchange Network (NEIN) grant to expand the existing San Francisco Bay Regional Data Center (RDC) to include the Sacramento-San Joaquin Delta and Suisun Marsh (Delta) for an estuary-wide data repository. SFEI received Delta data from public and private sector sources ranging from scientists, environmental program staff, managers, the public and other stakeholders.

DEDUCE: Delta Environmental Data for the Understanding of a California Estuary (Project)

The purpose of this project is to expand the existing San Francisco Bay Regional Data Center (RDC) to include the Sacramento-San Joaquin Delta and Suisun Marsh (Delta). The anticipated outcome of this project is an estuary-wide data repository where one currently does not exist.

New Manuscript on Pollutants in the Guadalupe River Addresses Key Questions (News)

Guadalupe River is contaminated with mercury mining wastes from runoff associated with the historic New Almaden Mining District in the upper watershed that produced 40 million kilograms during its working life (1850-1975) and with PCB and other urban pollutants from a long history of urbanization and industrial land uses.

SFEI has been monitoring pollutant concentrations in the Guadalupe River during winter storms since October 2002. The result is one of the world’s most extensive data sets on mercury, PCBs, and other pollutant concentrations and loads in an urban river.  In a recent manuscript, SFEI staff used the dataset to answer three major questions.

Find more data in CD3! (News)

The Contaminant Data Display and Download Tool is a public tool for accessing and visualizing contaminant data. All data are comparable to CEDEN, the California Environmental Data Exchange Network.

We are happy to announce the release of some new enhancements to CD3 including:  

Healthy Streams Portal (Project)

Healthy streams, rivers, and lakes provide safe drinking water, recreational opportunities, and important habitat for species ranging from the red-shouldered hawk to steelhead to crayfish and dragonflies. Maintaining healthy streams, rivers, and lakes can reduce the need for water treatment and water supply costs and make landscapes more resilient to climate change.

SFEI Journal Article on Mercury in Coastal Fish of Western North America (News)

A journal article published in April details the findings of a collaborative survey of contaminants in fish on the California coast conducted by the RMP, the California Surface Water Ambient Monitoring Program, and the Southern California Bight Program in 2009-2010. The paper used that strong dataset as a foundation for a broad review of mercury in fish on the coast of western North America.  This work was done as part of a series of articles summarizing mercury science for western North America in a special issue of Science of the Total Environment.

RMP Update (Project)

The Regional Monitoring Program for Water Quality in San Francisco Bay is an innovative collaboration of the San Francisco Bay Regional Water Quality Control Board, the regulated discharger community, and the San Francisco Estuary Institute. It provides water quality regulators with information they need to manage the Bay effectively. The Program issues a report each year, the Pulse of the Bay in odd years and the RMP Update in even years.

Clean Watersheds for a Clean Bay (Project)

The Clean Watersheds For A Clean Bay project is multi-year project focused on implementing the PCBs and mercury Total Maximum Daily Load (TMDL) water quality restoration programs, and is the next step in the effort to reduce loading of sediment-bound pollutants to the Bay. Funded by the USEPA, BASMAA, and 6 six of the Bay Area countywide stormwater management agencies, this project is evaluating control options to reduce mass loadings of PCBs, Hg and other pollutants from urban stormwater runoff to the San Francisco Bay. 

2014 RMP Sediment and Bivalve Data Now Available on CD3! (News)

In 2014, the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP) collected sediment and bivalve samples from San Francisco Bay as part of its long-term monitoring program. Results from these samples are now available on SFEI's Contaminant Data Download and Display (CD3) Tool. 

CD3: New Download Feature (News)

This release of CD3 features an advanced download tool for accessing all data for a project and the ability to dynamically generate Sum of PCBs.  Detailed instructions for using the tool's different features are provided in a pop-up box for easy reference. Visit to try out this new functionality!
