Development of a modular biotreatment systems for winery and brewery wastewater

2015-16: We are testing and developing an efficient Microbial Fuel Cell (MFC) treatment system that extracts and utilizes chemical energy from high-strength winery wastewater. The resulting water is of sufficent quality to make the water available for irrigation. Lessons learned will be used to inform the design of a larger pilot MFC system to be installed at D’Argenzio Winery

Sustainable water solutions

2015-16: Sustainable water, a principle of One Planet Living,is founded upon the practice of efficient water usage. We explore to what extent North Bay Schools engage in sustainable water practices.

Graphical user interfaces for non-technical users to explore rainfall, C02, and wildfire data

2015-16: Non-technical staff often have difficulty exploring environmental data sets that allow them to apply available data to current management challenges. Graphical user interfaces (using Matlab) create intuitive interfaces for non-technical users to explore rainfall and fire data.


Comparing and analyzing climates in the upper watershed and alluvial fan of Copeland Creek

2015-16: Rainfall and temperature vary considerably along elevational gradients. The weather station at the Fairfield Osborn Preserve documents conditions near the top of the Sonoma Mountain. This study investigates the optimal location for a weather station at lower elevations on the SSU campus.

Automated Sensor Network for Copeland Creek Headwaters

2013-present: The Osborn sensor network gathers data from weather stations, cameras and other sensors and transmits the information to the internet. The automated weather station provides reliable real-time data on the amount of rainfall and other climate variables in the upper watershed. A range of other sensors and coding are part of this sensor network development, including solar power design and installation, real-time displays of data, and new methods, such as backpacks and autonomous vehicles that can be deployed to gather data from watershed sensors.


Philosophy and Ethics of Water Choice

2013-16: One technology that is vital for survival but often goes unquestioned is our use of water and the philosophical, political, and social values that influence the decisions we make. We explore the ethical impacts of water use using a philosophical framework.

Predicting extreme rainfall in the Copeland Creek watershed

2014-16: California’s highly variable climate and growing water demands pose water-supply and flood-hazard challenges to resource managers. Mathematics students are using local data sets from the weather station at SSU's Osborn Preserve and UC Davis Bodega Marine Laboratory to evaluate the ability of regional models to predict rainfall in our region.


Development of an Ultrasonic Sensor to Monitor Water Use

2013-16: Monitoring water levels in a tank has always required a physical object of measurement to be submerged and often requires visiting the tank to check levels. We developed a low-cost ultrasonic depth sensor that accurately measures the depth of fluids (water, cooking oil, motor oil) up to four meters and displays the values on a monitor. 

Water Efficiency Projects on the SSU Campus

2014-15: Sonoma State has implemented a variety of water saving measures and technologies on campus, including the use of reclaimed water and low flow fixtures. Environmental and financial costs and benefits of a variety of measures are evaluated.

Power Supply Needs for Off-Grid Sensor Network in the Headwaters of Copeland Creek

2014: The Osborn Sensor Network collects and transmits data from sensors in the Copeland Creek headwatershed. Power needs for newtwork sensors (e.g., weather station, cameras, etc.) must be evaluated to determine the appropriate solar and battery requirements to ensure continuous data streaming. We evaluated the power needs (solar panels and 24V DC batteries) for an offgrid, lowpower wireless camera to be installed overlooking water sources on the Fairfield Osborn Preserve.

Geodatabase for Sharing Copeland Creek Watershed Data

2013-14: We developed a geodatabase to enhance sharing of data in the Copeland Creek watershed. The Google Map product uses fusion tables to create a clickable data-discovery interface. Users can click on location icons to identify the types of data collected, when they were collected and by whom. When possible, links are provided to on-line data.

Sencell circuit board

SenCell: A Low-Cost Cellular-Based General-Purpose Real-Time Monitoring System for Rural Areas

2013-14: We created a low-cost, solar-powered, general-purpose remote monitoring system with unique features such as open-source software and in-field configurability.The unit can collect and transmit data from sensors in any location where cell-reception is available. The flexible and modular SenCell architecture allows it to be used for diverse applications, including flood and fire detection, and real-time water quality and air pollution monitoring.

Low-Cost Irrigation Control Sensors (Smarden Project)

2013-14: We designed a low-cost autonomous garden sensor that can monitor environmental conditions (temperature, humidity, sunlight, and soil moisture) and respond by turning irrigation systems on or off. The system has potential to conserve water use by home gardeners, farmers, or wine growers.

Copeland Creek Watershed Evapotranspiration Project

2012: Evapotranspiration is an important but variable part of the water cycle. To better understand water cycle dynamics in the Copeland Creek watershed, a student research team constructed and installed a sensor network to continuously monitor environmental conditions and tree water loss in the headwaters at the Fairfield Osborn Preserve.
