Investigating the State of Morro Bay Estuary: State of the Bay Report 2020

    Every three years, the Morro Bay National Estuary Program publishes a State of the Bay report that uses data gathered by our staff, volunteers, and partner organizations to examine the health of the Morro Bay estuary and watershed. It provides important information about environmental trends and guides local efforts to protect and restore this special place. This year, we published a digital version of the State of the Bay report with additional multimedia content and information that we couldn’t fit into into the print version of the report. Today, we invite you to investigate the the health of …

A Day in the Life of a Field Tech: Eelgrass Monitoring, by Blake Toney

A staff member stands in waders in a puddle on the mudflat.

In today’s post, Blake Toney, former Morro Bay National Estuary Program Field Tech, reflects on an early morning spent monitoring eelgrass during a very low tide in Morro Bay.  5:40 a.m. I arrive at today’s site a few minutes before my coworkers to get my bearings. The sun will not rise for another hour, but already the dark sky has begun to take on a hint of blue so faint it becomes harder to see when I concentrate on it. The moon provides some light, enough for me to trek out across the mud after struggling to fit into my …

Morro Bay Eelgrass Restoration Update: May 2020

    Eelgrass in Morro Bay grows at a range of intertidal and subtidal depths throughout the estuary. Intertidal areas are exposed at high tide, while subtidal locations are always under water. Over the last few years, the Estuary Program has focused on transplanting eelgrass at intertidal locations. Focusing on shallower intertidal locations has been ideal for getting access to the mudflats on foot, and has allowed us to maximize our volunteer support. (Thank you, volunteers!) This spring, we are excited to have additional funding to expand our planting efforts to subtidal locations, too, as many intertidal areas off the …

Field Updates February 2020: Creek and Eelgrass

Creek Water Quality February was a month marked with warm temperatures and low precipitation here in the Morro Bay watershed. In February 2019, the San Luis Obispo CIMIS rain gauge received 7.48 inches of rain, with 57% of days during the month recording rainfall. Comparatively, this year’s rainfall has been much lower, with a February monthly total of 0.01 inches of rain and only one day with rainfall as of February 28. Low precipitation levels have led to low flows in our creeks, as can be seen in this picture of Dairy Creek, a tributary of Chorro Creek. The amount …

Field Updates January 2020: Eelgrass Success and Creek Water Quality

This month, our field staff have been busy monitoring eelgrass success in the bay and water quality in the creeks that drain to the Morro Bay estuary. Eelgrass monitoring and restoration success If you spent time out on the bay in January, you might have noticed the really high tides. January 2020 had King Tides, meaning that the high tides were much higher than normal. These extreme high tides are mirrored by extreme low tides. We always take advantage of these extreme low tides to monitor eelgrass, as we have a wider window than normal to conduct our monitoring. Eelgrass …

Updates from the Field, December 2019: wildlife, staff changes, and restoration

Morro Bay estuary with bat ray pits, Morro Bay National Estuary Program

    Wildlife observations The fall is a great time for observing invertebrates along the mudflat in Morro Bay, and lucky for us, we are out monitoring eelgrass every fall. This often leaves us wondering, “What is this?!”, but sometimes we find the answers while monitoring eelgrass health. For example, we have been seeing a number of egg masses such as this one, tucked away on blades of eelgrass. Considering the diverse array of organisms that utilize eelgrass as habitat, we were left wondering which creature had been laying the eggs. Sometimes though, you wander along the right part of …

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 …
