Family-Friendly Hikes Around Los Osos

    The land that surrounds the Morro Bay estuary is contoured by hills and valleys, studded with trees, and etched by creeks that take their time winding down to the salt marsh and entering bay. In short, it is a beautiful place that offers many opportunities to get outside and explore. But, as temperatures dip and the sun starts to set earlier in the day, many of us spend more time inside than out. Studies show that making time to enjoy the natural spaces around us by hiking, walking, or even just visiting with friends in green spaces can …

The “Smalls”: The Teeniest, Tiniest Sea Slugs In California

Guest post by Robin Agarwal   This is the fourth post in our Sea Slug of the Month series. Find tips for spotting nudibranchs from the comfort of your local dock at the end of this post! So you’ve been tidepooling along your local reefs and you’ve found a few nudibranchs: Opalescents, Sea Lemons, Spanish Shawls, Hopkins’s Rose, Triophas. Maybe you’ve practically tripped over ginormous squishy Sea Hares. Boring, right? What a snooze, all those flamboyant colors, shapes, and bizarre anatomy. After all, those nudibranchs are over an inch long, and therefore way too easy to find.  If this is …

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 …

Creeks to Coast Cleanup Success in Morro Bay

    No matter how far inland we live, we’re all connected to the ocean by water. Rain washes downhill and into stormdrains, creeks, and rivers before entering the sea. So, if we’re going to keep plastics, other harmful debris, and pollutants out of the estuary and ocean, we have to start inland. That’s the idea behind the Creeks to Coast cleanup, a set of 49 cleanups organized by local nonprofit ECOSLO. This massive cleanup effort took place last weekend all across San Luis Obispo County on International Coastal Cleanup Day. During the course of three hours,  1,840 volunteers picked …

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 …

    As summer winds down here along the Central Coast, schools are back in session and fall is just around the corner.

Creeks Our long-term monitoring program in the creeks continues with our staff and the help of volunteers. To see what we use the data we gather for, or learn more about what we do out at …

  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 …

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 …

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. …
