Practice will be the Jetty this weekend... see you in the morning ...
Marty, Mike, Kerry, Rocky, Dave, Steve & Oliver
Practice at the Jetty 4:30PM
See you Wednesday, the Coaches
A-Team Surfers: Practice is scheduled for Kelly Street Tuesday 6:30AM. If it's too big and closed out, we will promptly move to the Jetty. Call me at 6:25 AM sharp to confirm.
Practice will start at 9am at Roosevelt Beach - we will have Team Pictures for both High School & Middle School Teams/Clubs. The Team pictures will be taken with wetsuits on - so please be on time and suited up by 9am. If you are a Team Surfer and have a sponsorship deal thru one of the local Shops/Shapers please bring your sponsor's board that you ride - as well. We need all surfers to represent with the Board they ride in competitions in the picture.
Please be on time as the faster we move thru the picture taking portion the sooner we will be in the water, they say Sunday is supposed to be warmer than today!
Once the Pictures are taken we will split the groups and have practice

Rocky asked Amber Johnson, Kalea's mom to give us a quick run down on the question of surfing and Red Tide's on the San Mateo Coast. Amber is atrained Biologist and the Undergraduate Laboratory Manager at San Francisco State University...
I am so glad that Rocky asked me to address the phenomena of “red tides” with you. Red tide is a general term given when a group of protista reproduce so much that they actually change the color of the ocean (follow the link for more images of last years red tide). These protista are generally in one of the following groups; the dinoflagellates or the diatoms. A general term for these organisms is phytoplankton which refers to single celled organisms that make their own food (like a plant) and float around in the ocean. The ocean actually changes color because these organisms are colored so they can photosynthesize (the same reason that trees are green). Why am I so eager to cover this topic with you? Well during the course of my graduate studies in marine biology I had the pleasure of working in a Phytoplakton Ecology lab at the Romberg Tiburon Center for the Environmental Sciences. I spent three years working with relatives of the organisms that are coloring our water red and in general, phytoplankton never ceases to amaze me.
Phytoplankton are single celled microorganisms that live in the ocean (there are freshwater species as well). They are not animals or plants, yet they have characteristics of both. Many photosynthesize, meaning they make their own food, like plants. Many also are motile, meaning they move around like animals. Most are incredibly beautiful and have inspired many artists to try to recreate their intricate shapes and patterns. Phytoplankton are ALWAYS found along our coastline and in fact they are considered to be at the base of our food chain. Without these microorganisms to fuel the critters that live in the sea, the entire food chain in the ocean would collapse.
You might be wondering, if these microorganisms always exist, why is our coastline blood red right now? In your garden, if you add water, sunlight, and nutrients (often in the form of fertilizer) you get increased growth. The same is true in the ocean. Right now we have the perfect conditions to grow phytoplankton. We have warm sunny conditions and we have freshwater runoff which happens to carry lots of nutrients from the local farm lands (in other parts of the year we have upwelling, which provides fresh nutrient rich water – but that is a story for another day). In periods like these, the phytoplankton bloom and reach such densities that they color the water.
Here is a question that many of you have: is my child in any danger? The simple answer in NO: in my opinion, right now it is fine to surf in phytoplankton. There may be hundreds of different types of microorganisms that form these phytoplankton blooms or “red tides”. Of these only a few dozen create toxins that can kill fish, birds and even people. These are called Harmful Algal Blooms or HAB’s. Along the coast of California, the only way for you to ingest enough of these toxins to have a lethal outcome, is though bioaccumulation. Bioaccumulation is when an animal ingests the toxin and stores the toxin in their tissues (often not hurting the animal) then the human ingests many of the animals that previously consumed the toxin, thereby accumulated lots of the toxin into the human tissues. This is why we don’t eat shellfish caught during a HAB. This is VERY general explanation of a HAB. HAB’s actually refer to any bloom that causes harm. The harm can be caused by a toxin or can cause harm in a number of other ways which I can tell you about at another time. Some of you may have heard of blooms in the Gulf of Mexico and in the Mid Atlantic which release toxic aerosols into the air and caused mild irritation to the eyes and throat of people swimming in the water. While this is true, at the time of this writing we do not have these species of HAB along our coastline.
Now you know, just because you see a phytoplankton bloom, you are NOT necessarily seeing a HAB. A majority of what blooms along our coast is the normal phytoplankton that is necessary to fuel our food chain and keep our ocean’s ecosystem healthy and thriving.
Surf Club Members-
As part of the CSSL league partipants are required to perform some community service. Please join the HMB Surf Club and other San Mateo County Parks volunteers... by volunteering and helping to cleanup the coast. We will be meeting at the Half Moon Bay Kayak Co. at 9am and working our way down the beach to clean up Surfers Beach. A spot we all have an interest in keeping clean.
See you on Saturday-
Practice at Kelly Street 4:30PM
See you Sunday, the Coaches
The high school "A-team" surf practice will be held at Kelly Ave. on Tuesday Sep-21 at 6:30 a.m. Please arrive promptly so that we can run through a few heats and award plenty of points.
Also, don't forget that we have a surf team meeting on Tuesday night at 6 p.m. at Round Table for families to go over some important topics for the season. We will also be turning in CORE paperwork and checks for the Boy's & Girl's Club and CORE dues, which can be made payable to the Boy's and Girl's Club of the Coastside.
We will be holding our 2010/2011 season introduction meeting for the Parents of the Surfers at Round Table at 6pm on Tuesday September 21st.
At the meeting we will cover:
- Introduction of the Coaches
- The Core Scholastic Surf League: what to expect and hopefully the competition schedule.
- The CSSL paperwork & sign up of those who wish to compete at either the High School or Middel School level...
- The paperwork for those who wish to just be Surf Club Members (for those who haven't completed it already)
- Collection of registration fees for the team ($50) and/or the club ($10)
- How you can help if you are so inclined
We look forward to seeing you there & your kids if you bring them...
