Photo Contest: Share the Beauty and Bounty of Morro Bay

    Estuaries worldwide deserve our attention and protection. Every year, Restore America’s Estuaries hosts National Estuaries Week during the third week of September to recognize the many benefits that estuaries provide. These places where freshwater rivers and streams meet the salty sea are biological hot spots, home to a wide range of wildlife including protected species like steelhead trout, Southern sea otters, and tidewater gobies. Estuaries provide a nursery for commercially important fish that mature and then venture out into the ocean. Their marshy extremities filter and absorb stormwater runoff, removing pollutants before the water enters the bay and …

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 …

Photograph Friday: Appreciating Our Corner of the Earth

    This week marks the 50th anniversary of Earth Day.  In 1970, the first Earth Day drew 20 million people together in support of a more environmentally sustainable future. At the time, that was 10% of the total population of the United States. We can trace the roots of the Morro Bay National Estuary Program back to that day, which set in motion a decade of environmental reforms and grassroots work for a greener future. In 1972, the Clean Water Act established pollution control programs and protections for surface water quality. In 1987, Congress created the National Estuary Program …

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 …

    Cerberilla pungoarena (Collier & Farmer, 1964) is one of those rare nudibranchs you may never see: only a few subtidal specimens have been reported since the mid-2000s. But now, fifteen years later and further north than they have ever been seen before, a single specimen of C. pungoarena was spotted and photographed a few months ago in shallow water in the Morro Bay Estuary by two intrepid nudibranch enthusiasts, Laura Schachterle and Thomas Hintz.  Nudibranchs are shell-less marine molluscs commonly called sea slugs. There are over 130 species of nudibranchs found in California, many brightly-colored. “Great find and …

Help Scientists See the Future: California King Tides Project 2020

windy cove king tide 2019

  What is the California King Tides Project? Scientists need you to be their eyes on the ocean between January 10–12 and February 8–9, 2020. On these dates, the California coast will experience the highest tides of the year, commonly called King Tides. These extreme tides often encroach on infrastructure, submerging coastal access stairways, swallowing beach-side trails, overwhelming boardwalks, surging into storm-drains, and flooding roads. They can also inundate coastal habitats that aren’t typically submerged, like higher marsh areas or even dune scrub. With the rate of sea level rise increasing worldwide, what we consider ultra-high tides today may be …
