On the Oregon Coast

Harper and I spent this past week on the Oregon coast with a group of marine biologists who were working to better understand the effects of climate change. While there we were able to help collect an assortment of data on Pisaster sea stars and dissect mussels. It was really very interesting. One day as we drove down the coastal highway toward our field site I saw a group of tourists pulled over at the side of the road snapping photos of the rocky surf. Knowing they'd soon climb back into their cars and head off to some other spot without ever really knowing this one, I thought about  how fortunate we were to have the opportunity to become a part of of this little swatch of coastline - no matter how briefly.

At the end of the week we flew home and I have now begun to think about what this experience will mean to me and my students next year in the classroom. That was the point - to live and work alongside real scientists in hopes of rethinking the ways in which we go about teaching things like scientific inquiry, animals, or geology. Many of us came back home with more questions than answers but that is part of the process.

This was "home" for Harper and I in Oregon. It was located just a few hundred yards from the ocean.

This was the second house where a few other teachers were staying along with the team of marine biologists. The yard, like most of the other houses in this neighborhood, was full of tall beach grass. No lawn mowers!

To the north we could see the mountains.

The crew from the  Helmuth Lab arrived two days before us. They spent that time dissecting hundreds of mussels they had collected from the tide pools. Here they have a collection of mussel gonads that were being shipped to a lab in Italy.

When we arrived at the field site each morning we would pull on our rain gear.

The site we worked at was named Strawberry Field. There was a high wall which dropped down into a band of sand and basalt. The tide pools were located just outside the frame of this picture, to the right.

The site was a little tricky to reach due to all the rock hopping we had to do. This was made more difficult by the task of carrying in the gear. However, there were fifteen of us and everyone was happy to pitch in.

The experiment we were supposed to be working on did not pan out. We were going to be collecting the heart rates of mussels located throughout the tide pools. However, the sensor was not cooperating so we were reassigned.

This is a Pisaster sea star. They are much harder than you would expect. Their backs feel like a course rock.

The Pisasters spend their days eating mussels. To do this they pry open the shell,  release their stomach, and digest the mussel right inside the shell. In this picture you can see a mussel being eaten by the Pisaster. They can eat entire beds of mussels. You can see their tube feet latching on to the mussel.

Pisasters can be purple or orange. Once we developed an eye for seeing them we found they were everywhere.

Anemones sit at the bottom of the tide pools waiting for something to drop into their center. When this happens, say a small mussel drops into the water, the anemone closes around it and eats it. If you put your finger in the center of the anemone it will close. It feels a bit sticky but poses no danger to a human. No fingers were lost on this trip.

One of our jobs was to establish a transect (a fixed path) where we would observe, measure, and describe the location of Pisasters in relation to the pools, waves, and sun. We would then remove the Pisasters and calculate the average length of their arms.

Two of the  measuring tools we used were a laser level and measuring stick. This helped to establish how high each Pisaster was above the water line.The measurements we collected with this gear were a bit crude but the team would be able to use this data to more accurately calculate the measurements later using a more sophisticated tool that incorporates GPS technology.

When we were missing a much needed tool (in this case, a measuring tape) we would improvise. The girls from the Helmuth lab made us makeshift rulers from waterproof paper to use in measuring the lengths of the sea star's legs. This data will be recalculated into standard units back in the lab.

Careful recording of data was an important part of all our field work. When we would return to the houses the teachers were often free to eat, rest, and talk while the scientists kept working - entering data into their computers. All this data will take quite some time to analyze back at USC.

We were extremely thankful for the enthusiasm and patience of the scientists. We asked lots of questions and they answered every one.

Another of our tasks was to help dissect mussels. We harvested the gills, aductors, and mantles. Each was carefully removed, wrapped in tin foil, and put in a cooler with dry ice. These were shipped back to their lab at USC. The dissections were especially difficult with cold hands.

Harper spent time exploring the tide pools with a friend. They found all sorts of animals.

This is a small crab they found crawling along the rim of one of the tide pools.

She wasn't too sure about holding the sea star but reached out and grabbed it anyway. By the end of the first day she was scooping up everything she could catch.

There weren't a whole lot of sea urchins at Strawberry Field but Harper did manage to find one or two.

Of course, part of the fun is just climbing up and down all those rocks.

Some mornings were colder than others. On this particular day it was raining and very cold. We rushed to get in our work before the thunderstorms rolled in. We just barely made it.

Another job was to remove tube feet from the Pisasters and place them into small tubes to be tested back at the lab. These tube feet look like small straws. The Pisasters use them to hold on to the rock face. We were assured they grow back and it feels no worse to the Pisasters than a haircut feels to us. While I don't know if this is true or not I do know that sea stars don't exactly offer up those tube feet to the forceps and scissors. This job really took some patience and a game plan.

Before collecting the tube feet we took the Pisasters' temperature by probing each of their arms and then finding the mean (aka average).

All this data was called out and someone would record it into the field journals. They were made of waterproof paper.

The tide pools ranged from the tiniest of puddles to rather deep pools. The surrounding rocks at Strawberry Hill were sometimes completely covered in mussels, such as in this picture. We did our best to avoid walking on the mussels but that was often impossible.

We finished each day around noon or so and then had the rest of the day to ourselves. Harper began keeping notes for a blog post of her own.

There were a total of three kids on the trip. One afternoon I  took them on a walk to the beach to play. The water was frigid but they still enjoyed splashing around.

The beach was littered with driftwood from Japan. One day we even found a deal seal on the beach. It was a sad sight.

Back at the house the teachers shared their experiences and thought about how this experience of living the life of a scientist would change the way we taught the students in our classroom. We were all looking for ways to engage our kids in authentic scientific pursuits.

Some of this debriefing also took place in more informal settings. We were all so excited by all we were learning and experiencing.

Our final day was at a different site - Boiler Bay. This site was beautiful but not as interesting. The water splashing up into the rocks was not so nutrient rich as it was back in Strawberry Fields. For this reason there were far fewer, and less developed, mussels. Fewer mussels meant fewer sea stars. However, we did see some sea snails and lots of urchins.

Harper's favorite part of Boiler Bay was the waterfall. She pulled off her rain gear and jumped right in. Twenty minutes later she was shivering back in the van. It was cold!

None of these sites were easy to access. Boiler Bay was the most difficult. We had to navigate a steep descent down a series of very large rocks.

These cages were left by other teams of scientists as part of long-term data collection. Our team swapped out "robo-mussels" that were designed to collect data over the next year.These were glued down to the rock surface alongside the other real mussels.

There was a nearby cave with lots of sea lions inside. This piece of nature cost us $12 per person to see. And, of course, we had to walk through a gift shop to reach the cave. How sickening. The very next day we came upon about 60 seals sun bathing on the beach. They let us walk within about 15 feet from them. We just sat there in awe of being so close. And we didn't even have to buy a t-shirt or pay admission. Go figure.
