  Watching the Highway 41 Fire from the Morro Bay estuary On August 14, 1994, the Highway 41 fire broke out on the Cuesta Grade. Ruth Ann Angus, local photographer, writer, and long-time supporter of the Estuary Program, was out kayaking on the bay with a friend when the Highway 41 blaze began. As Ruth Ann recalls, “We paddled all the way back to Sweet Springs and as we turned around there, I spotted the puff of smoke in the sky. I knew it was bad so we immediately began paddling back to the Marina area….” She took photos on …

The truth about sunscreen: its effects on us and the environment

Summer is coming in hot! Iced tea, pool days, and movie nights are fast approaching. With all the excitement that comes with summer, you might not be thinking about the invention that allows our skin to survive the brutal rays of the sun—sunscreen. Whether you are a fan of old-school white goop or spray-on, most sunscreens are made out of the same basic ingredients. The main difference lies in how the active ingredients work to keep you from burning. There are two types of sunscreen, chemical sunscreen and mineral sunscreen, which is also known as physical sunscreen. Chemical sunscreen vs. …

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 …

Morro Bay Wildlife Spotlight: Mystery Species Revealed

Mystery species number 1

  In last week’s post, we shared photographs of four species native to San Luis Obispo County and asked you to identify them. Today’s post reveals all four mystery species and shares information about each one. Wildlife Spotlight: Mystery species #1 Common salp (Salpa fusiformis) These ethereal-looking creatures are sometimes mistaken for jellyfish, but they are much more complex. In fact, they are more closely related to humans than they are to jellies. This is because, as larvae, salps have a simple backbone called a notochord, which is composed of a tissue similar to cartilage. Though the notochord all but …

Earth Day in Morro Bay 2019: Biodiversity and Blue Carbon

  Our choices, both big and small, affect the estuary At the Estuary Program, we work toward the health of the Morro Bay estuary for the benefit of people and wildlife every day. We complete big projects that have a correspondingly large impact, like our rural road restoration project that is projected to keep more than 12,200 tons of sediment from entering the estuary through 2027. We also make small day-to-day decisions, like choosing to stay on established trails when we conduct fieldwork or hike on our own, rather than cutting new ones. We don’t usually announce those small choices, …

Get Ready for Clean Boating on Morro Bay

  With the spring winds whipping along the Embarcadero and whitecaps on the bay, summer might seem far away. But, in just a couple of months, school will let out and prime boating season will begin. Helping boaters keep our bay clean This fall, the Morro Bay Harbor Department distributed kits that included spill prevention, containment, and response materials to all 27 boat-docking stations along Morro Bay’s shoreline. These kits make it easier for boaters to avoid spilling oil and other hazardous materials into the estuary. They also provide instructions, personal protection equipment, and cleanup materials that enable boaters and …
