  A mysterious disease called Sea Star Wasting Syndrome (SSWS) has been causing mass mortality of sea stars along much of the Pacific Coast from Baja California to the Gulf of Alaska. Twenty-two species of sea stars have been affected by it, making this a die-off event of the greatest magnitude, spread over the greatest geographic area to date. Melissa Douglas, Associate Research Specialist at University of California, Santa Cruz, is an expert on the syndrome. She is concerned about the spread of the disease. As she says, “Past SSWS outbreaks were restricted to Southern CA and Baja Mexico. Now …

Where is the water? Tracking water in our creeks

While pressure transducers and other automated equipment collect important data, much of our long-term dataset is collected by hand. Volunteers measure water quality each month by going out to creek or bay sites with equipment in hand. They take note of things like water temperature, dissolved oxygen content, and other measures that indicate creek health.

    Measuring the water level in local creeks gives us valuable data. We collect this data with pressure transducers. A pressure transducer is a water-level measuring device that we install by submerging it in the creek. It continuously measures the pressure of the water pushing down on it and converts it into a height measurement. These instruments can collect data for months or even years. Pressure transducers can be used in a wide range of applications, from weather stations, to flood control, to tracking reservoir water levels. We use these devices in our local creek systems to estimate how much …

Clean Water, Great Life – Bay Water Quality Update Part II

Volunteers monitor DO levels in the early morning hours because that is typically when we find the lowest levels of the day.

  The Morro Bay estuary is a special place that is central to many of our lives, providing a beautiful place to live, work, and visit. We play in these waters and enjoy the food they provide. These waters are also home to countless species of plants, fish, and invertebrates. The monitoring efforts of the Estuary Program and its volunteers help to determine if Morro Bay provides clean waters that can support sensitive marine life, as well as activities such as swimming, boating and fishing. Last week, we looked at what the Estuary Program’s monitoring efforts can tell us about …
