Field Updates November 2019: Eelgrass, wildlife sightings, weather

    November was a busy month for our field staff. Mapping eelgrass and algae The Estuary Program has been mapping submerged vegetation, such as eelgrass and algae, for more than fifteen years. This is done by having a plane fly over the bay taking a series of images, including a multispectral image. We try to repeat this survey about every other year, with 2019 being an eelgrass flight year. Multispectral imagery Multispectral imagery is produced by sensors that measure the reflected energy within several bands of the electromagnetic signature, usually capturing light not visible to our eyes. You can …

Field Updates, October 2019: Eelgrass Mapping, Ground-truthing, and Cal Poly Partnerships

Andi, eelgrass technician.

  Eelgrass fieldwork depends on tides Fall is a busy eelgrass season for field staff at the Estuary Program. The exact timing of our field work depends on when the good low-tides occur, which varies slightly from year to year. This year, October had a few days that had tides low enough to expose the eelgrass during daylight hours. This doesn’t always happen—sometimes the low tides we need happen after sundown and before sunrise. We were glad to see good tides in combination with good timing because we have a few different projects going on. Monitoring permanent eelgrass plots First …

Field Updates September, 2019: Stream Profiling and Bay Monitoring

  Fall is in full effect here on the Central Coast, and we are enjoying the crisp mornings and clear days that go along with it. Fall is typically the slowest time of year for fieldwork so we are mostly catching up on activities back here at the office and planning upcoming projects, but that’s not to say we haven’t been out in the field this month. Thank you, cleanup volunteers! We hope some of you got out this month for Creeks to Coast Cleanup Day, where nearly 2,000 wonderful volunteers picked up about 11,500 pounds of trash from our …

Cuesta College dives in to help study eelgrass declines in Morro Bay

    A guest post by Dauphiene Parks During June 2019, a group of fourteen spirited Cuesta College Marine Microbiology students came together under the kind and careful guidance of professors Laurie McConnico and Silvio Favoreto. The mission was to explore the Morro Bay Estuary and examine the local eelgrass population. We quickly learned that 97% of the eelgrass in the Morro Bay Estuary has been lost, and that eelgrass habitats can provide an estimated $87,000 in ecosystem services annually. We were excited to be a part of this class that allowed us to earn college credit and work on a …

Field Updates, June & July 2019: Creeks, Road Restoration, Eelgrass

Shows a volunteer conducting water quality monitoring

  With summer in full swing, field staff at the Morro Bay National Estuary Program have greatly appreciated the long days. As always, we have been busy out in the field, collecting data from the watershed. Here are some of the things we’ve been up to recently. Creeks Our ongoing monitoring effort of the two subwatersheds, Chorro Creek and Los Osos Creek, that drain into Morro Bay allow long term trends to be established and we can see if current conditions vary from historical patterns. Chorro Creek is the main creek in our watershed, draining about 60% of the total …

Field updates April & May 2019: Monitoring Eelgrass and Creek Health

Two members from the Watershed Stewards Program lay out eelgrass blades on a white board for counting and photographing.

    Fieldwork season is in full swing now for us here at the Morro Bay National Estuary Program, and we have been busy hiking around the creeks and estuary to continue monitoring our local watershed. In April and May, we monitored eelgrass and conducted bioassessment monitoring to help us see how healthy our creeks are. Eelgrass monitoring Eelgrass monitoring continues as usual when the tides are low enough to let us collect data. This past month, there was a good window spanning multiple days where we were able to monitor for a couple hours each day to check on …

Field Updates February 2019: Wet weather, eelgrass restoration, and creek monitoring

A picture from the bridge at our monitoring site on Canet Road, overlooking Chorro Creek. What a difference a week and some good rain storms will do!

    Fulfilling our mission to protect and restore the Morro Bay estuary for people and wildlife requires a lot of hard work in the field. At the Estuary Program, that often entails doing research, restoration, and monitoring work out on the estuary and along the creeks that feed into it. Read on to see what we’ve been up to during the past month during this wet weather. Eelgrass February eelgrass restoration details This past month, we have been busy taking advantage of some of the year’s lowest tides to replant eelgrass throughout the estuary. The weather didn’t want to …

Field Updates January 2019: Eelgrass, Stormy Monitoring, Wildlife

Once the water levels dropped to safe wading levels, we went out to check on equipment and measure stream flow on Pennington Creek. This is at the site that previously had a fish passage barrier. The barrier was removed over the fall, opening up miles of Pennington Creek for migrating steelhead trout. Partners at other organizations have seen returning adult steelhead in a few other creeks in the county, so we are keeping our eyes open for ones in our watershed as well.

In the first two blog posts of the Factors that Affect Eelgrass Growth in Morro Bay series, we learned that there are many factors that influence eelgrass growth in estuaries. In this two-part post, PhD candidate Erin Aiello explores the importance of light levels and sediment properties and how they change across the bay. This is the second half of the post; read the first half here. Erin Aiello, Guest Author Erin Aiello is a native of the central coast, having grown up in Cambria.
