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 August 2017: Eelgrass and Creeks

Matt, our Field Technician, works to identify and count the stages of the flowering shoots in a one-meter by one-meter plot.

  See what our volunteers and field staff have been working on during the past month. Eelgrass We completed our second round of 2017 small-scale experimental eelgrass transplanting in July, in collaboration with Cal Poly and California Sea Grant. In total, we planted seventeen one-meter by one-meter plots of eelgrass including nine in the forebay (across from the Tidelands boat launch) and eight in the midbay (across from Morro Bay Oyster Company). Though our midbay location was not as successful as the forebay site, we were able to glean useful information from these efforts, including which areas to target and …

Field Updates July 2017

George and Estuary Program volunteer, Nick, finish planting eelgrass shoots within a one-meter squared plot.

    Estuary Program staff and volunteers were hard at work in the field this past month. Fieldwork in July focused on preparing for a second round of eelgrass restoration. As you may recall, we collaborated with CalPoly on a similar effort in March, 2017. This effort was conducted earlier in the year than in past efforts in hopes that the eelgrass would become established before large macroalgae blooms, which typically occur during the summer here in Morro Bay. After four months, we were seeing growth and expansion of eelgrass at our forebay plot (or, eelgrass had expanded outside of …

Eelgrass Restoration in Morro Bay Spring 2017

    Greetings, readers! This is Catie, the Morro Bay National Estuary Program’s Communications and Outreach Intern. I had the privilege of participating in the Estuary Program’s most recent small-scale experimental eelgrass restoration effort. We want to fill you in on the process here. Eelgrass (Zostera marina) plays a number of important roles in the function and health of the Morro Bay ecosystem.   Its long blades form an underwater forest, which provides a diverse crowd of creatures a place to rest, find food, and spawn. These are some of the creatures that we found during the replanting effort: The …

October Field Updates, 2016

Here, Shane places the quadrat at meter 75 of our 150-meter transect.

Fulfilling our mission to protect and restore the Morro Bay estuary for people and animals requires a lot of hard work in the field. Read on to see what our staff and volunteers have been up to during the month of October.   Fish trawl study We started off the month by helping Cal Poly Professor and California Sea Grant Extension Specialist Dr. Jennifer O’Leary conduct fish trawls in Morro Bay. In 2007, seven different sites around Morro Bay were trawled to catalog what species were present. Now, after the decline of eelgrass beds in the bay, the same sites are being trawled again …
