This blog will be following my San Francisco Expedition with National Geographic and the Smithsonian
Institute. It will also follow my own work on my senior research project for LSSU.

Day 7: Marin Headlands and Nature Bridge

Last night was fairly leisurely compared to the last few nights. It was nice being able to have a night to myself again. Again, it was a nice morning. I was able to wake up at my own pace and wasn't feeling rushed at all. Had to pack up for the last time which was a little sad. But, the breakfast at La Boulange (five pounds gained thanks to that stupid bakery). Come to find out the bakery was bought by Starbucks not too long ago. Honestly, not too surprised by that.

After another breakfast of an orange cinnamon morning bun, we loaded up the vehicles and drove out to the Marin Headlands which is located on the other side of the Golden Gate Bridge. Still laugh at all the hype about it. Doesn't even compare to the Mighty Mac. Even though our next site wasn't too far over the bridge, it still took almost 20 minutes to go five miles thanks to construction and a five minute wait for a one lane tunnel into the National Park.

We were met at the site by Ann of NatureBridge who informed us as to the itinerary for the day. We would be visited by groups of about 16 Fifth Graders every hour for about half the day. All that really needs to be said about that is it was intense. The kids were great though. They were very eager to learn and get their hands dirty. I couldn't believe how knowledgeable some of these kids were!

We had the kids find sites that they thought had the most biodiversity. They chose some excellent sites and their rationale was spot on. We all had a great laugh at some of the antics of a few of the kids. It was a great experience for me and the kids. I really want to start a program like theirs here in Michigan.

After our last group of children we were taken on a small tour of the NatureBridge campus. The campus was created from the remnants of an old Army base in that location. We then set up our equipment in the student laboratory space. That was the final part of my role in the expedition, which was difficult since I was finally in my element and the rest of the team were looking to me for identifications, ideas, and information. We said some simple goodbyes and that was it.

Since I had a few hours before I needed to catch my flight, I decided to stop and grab a bite to eat. I headed toward the airport, but I made a pit stop in Japan Town. I really wanted some good Japanese cuisine before returning home. I was gone for about half an hour and when I returned to my vehicle I found that someone had broken into it and stolen my backpack and camera bag. I immediately called the SFPD and reported the theft. It was a disheartening end to the otherwise fantastic expedition. That was the reason behind the delays in posting. I will be posting some pictures of my last day (thankfully, I uploaded them on to David's computer before leaving) as soon as I receive them.

Day 6: Transition

We were lucky this morning and had a reprieve from the 5am wake-ups we've had all week. It was nice to be able to get a little sleep and then be able to enjoy a nice breakfast. The weather was giving us a nice send off from Pillar Point today. The last day for me on the reef was invigorating. The wind was kicking up some great waves (too bad I didn't have time for some surfing). Sunshine through the light cloud cover created an amazing ambiance to our search for the final location for the cube.

The main goal for today was to actually determine the final placement for the cube. The problem we seemed to running into was the vast abundance of great locations. Some of the locations that could potentially be the best placement were inaccessible. Others were too open to the destructive forces of the waves (although, oddly enough, had some of the best diversity). But, the place that was chosen was a ledge that I had pointed out.

The ledge was located in a narrow crevasse that opened to the ocean and would intermittently fill and drain as the waves came in. The water would gently fill the crevasse and it seemed to allow for a great diversity in the organisms that called it home. We played around with placement for quite awhile to find the best spot for highest diversity. A lot of photographs were taken with David placing the cube. Unfortunately, I will have to return home before the actual placement is made. But, tonight we will be moving to the next site in the Marin Headlands. Should be fun!

Day 5: Sample Collection and Processing

First of all, I need to apologize for being a day behind on my posts. We have had really late nights and very early mornings that have caught up to us. Our second day out on the reef was extremely successful. We were able to collect over 30 specimens. It was a great day. The sun was out and the temperature was perfect. We really could not have asked for a better day for collection.

It was another early morning. We had to rise before the sun came up in order to be in position for low tide. Yesterday, my pants (even rolled up above my knees) were soaked, so I decided to where my swim trunks. It turned out to be a smart move on my part. We needed to collect all of the specimens that were in the vicinity of the cube, since they are found in the same habitat and could reasonably be considered to have passed through the cube.

I caught two crabs and a Sunflower Starfish. One of the crabs was pretty cool. It had barnacles half encircling its carapace making it seem like it had a crown (see picture). The Sunflower Star was really slimy, but it was really soft as well. Some of the other Stars were hard and rigid. I had to go in up to my chest to get the big crab and the Sunflower Star. The water was super cold. Oddly enough my legs felt fine in the water. It was my chest and stomach that were cold.


We went back to the house to process the sample soon after we collected our samples. The photographs that we were taking needed live specimens and therefore required us to quickly process them (identify, photograph, then take DNA samples). After the photographing I assisted Dr. Christopher Meyer in taking DNA samples for the BioCode project. The BioCode project is attempting to bar code (genetically) all of the organisms on the Earth. It is a bold attempt, but from my point of view it is a good endeavor.

All in all we sampled 31 specimens: Flabellina trilineata, Rostanga pulchra, Cadlina modesta, Geitodoris heathi, Doris montereyensis, Limaeia cockerelli, Diaulula sandiegensis, Doriopsilla albopunctata, Phidrana hiltoni, Triopha catalinae, Peltodoris nobilis, Patiria miniata, Strongylocentrotus purpuratus, Henricia pumila, Tonicella lineata, Nereis vexillosa, Fissurelli bimaculatus, Epiactis prolisera or Aulactinia incubans, Heptacarpus sitchensis, Pagurugranosi manus, Tonicella lineata, Anthopleura elegantissimal, Pagurus samuelis, Celliostoma ligatum, Paguristes bakeri, Pagurus hirsutiusculus, Pachygrapses eressipes, Cancer entennerius, Aglaophenia sp., and Aglaophenia sp.

A polychaete worm (one of my favorites)

After we caught this Starfish it released its babies. They look like the noodles in Chicken and Stars soup.

A couple of anemones

This shrimp was pretty cool. Its entire body was green tinted, but completely see through.

Our specimens

This tiny crab was about the size of the nail of your pinkie finger.

This was an awesome Nudibranch

A Chiton

This was the Nudibranch I photographed the other day

Another Starfish

The shell of this snail was really cool. It was striped all along it in a spiral pattern.

More of our specimens

A Purple Sea Urchin and some snails

This bucket was mostly filled with different species of snails


This was the crab I caught at the same time as the Sunflower Star.

The shape of this crab was unique in that it was triangular

This was an awesome Nudibranch.
