MSI takes to the tidepools for a treasure hunt of nature's beautiful intertidal secrets. We'll spend the evening taking advantage of the low tide to reach the outer edges of Pillar Point, and take in spectacular sunsets as we slowly retreat to shore. Will we find crabs, sea stars, eels and octopus!? This is a great all-ages, family event. $10 for MSI members, $20 for non-members. Space tends to fill up for these events quickly, so please RSVP soon.

California Coastal Cleanup Day     Saturday, September 25th      9 am ~ 12pm

    Every year MSI spearheads clean-up sites in Half Moon Bay, and with the aid of over one hundred amazing volunteers lasy year picked up seriously gross amounts of garbage. This year, we're looking after even more coastline, on the ocean as well as the Bay. MSI will provide gloves and bags for collecting waste and recycling. HOWEVER, a theme the state is encouraging this year in an effort to lessen the environmental footprint of the day is to bring your own clean-up supplies (pails, light garden gloves, etc.), if you have them.

      Contact Aaron if you can help out at Poplar Beach or Pillar Point in Half Moon Bay. RSVP is not required, but gives us a better idea of supplies needed. Last year we had lots of great prizes and gifts for our cleanup crews, including yummy fresh organic yogurt, dinner gift certificates and wine! What could we entice you with this year?

     Participation in our Half Moon Bay clean up sites are free, but a team starting at MSI will be cleaning up Redwood Creek.... by Canoe!  Participation is $20 per MSI member, $30 for non-members. Click below to register for our canoe clean-up!

Join MSI and our friends at Elkhorn Slough Safari to learn first-hand about one of California’s most spectacular estuaries.

A great family outing! MSI Member cost is $20 for kids (under 10), $30 for adults. Non-member price is $30 and $40, respectively. Space is limited to 20 people, so RSVP now for a wildlife adventure to remember!

Raise your flippers if you want to see cool marine life!

 If you have ever wished to learn more about the amazing sharks, crabs, fish and sea stars from the Bay and nearshore Pacific Ocean, here is your opportunity. Trained docents will lead you on a hands-on tour, and guide you in touching and handling marine life! This Free event is a great way to get to know MSI and share our resources with your friends.

MSI loves sharks, even if they can be a little spooky! Our special Shark Day invites one and all to learn about these amazing creatures, from the Great Whites that swim just off our ocean shores, to the gentle Leopard Sharks that are common in our Bay. We will be feeding and touching our local Leopard Sharks in our teaching aquarium, and viewing information about the vital role of these top predators around our world's oceans. $10 for members, $20 for non-members - advanced registration required.

Plankton Day!     Saturday, November 13th      9am ~ 11am

Better than science fiction, we'll learn how these plants and animals survive and build the basis of the whole food web. This event is $10 for members, $20 for non-members - advanced registration required.
