Mitchell Bay, SJI to Prevost Harbor, Stuart Island.
After stopping at Roche Harbor for lunch and switching captains, we began sailing towards Stuart Island. At 14:00 we deployed the CRT hydrophone. The cable for the hydrophone was very sensitive causing interference and picked up a lot of flow noise. At 14:30, the hydrophone array was deployed.
There was still some flow noise interference, but it was much better than the CRT. As we reeled in the hydrophone array at 14:50, a group of Dall’s porpoises swam alongside the Gato Verde. There were 5-6 which included a hybrid with a Harbor porpoise. They were seen at latitude 48 deg. 43.08 min. N and longitude 123 deg.14.90 min. W.

While the Dal’s porpoises were riding around our boat, a male elephant seal poked his head above the water for a minute.

Just two days after having our first encounter with the transient killer whales, another marine mammal drew our attention. We were practicing deploying the linear array of hydrophones and comparing the differences between it and a single hydrophone in the afternoon of Wednesday April 22nd. As Peter was reeling in the array, a group of 5-6 Dall’s porpoises began swimming in the wake created by the bow of the Gato Verde. They swam with us for a good ten minutes, easily surpassing the boat just to fall back underneath again. Everyone ran to the bow of the boat and sat on the trampoline (net) between the two hulls of the boat. There were a few times that the porpoises surfaced under the trampoline seemingly to get everyone to scream in startlement.
Having fun swimming with our boat.
There was one porpoise that was determined to be a hybrid between the Dall’s porpoise and the Harbor porpoise. The animal was gray and white instead of the custom black and white of the Dall’s porpoise. The hybridization between the two species of porpoises always seems to occur with a male Harbor porpoise and a female Dall’s porpoise.  The offspring is always seen with the Dall’s porpoises because the mother raises the young.
These animals are being massively hunted in the Pacific Ocean by Japan. When the International Whaling Committee banned commercial whaling, fisherman began focusing their attention on the Dall’s porpoise. More information about this animal can be learned at http://dallsporpoise.org/, and what you can do to help their plight.

Snug Harbor to Snug Harbor
There was a heavy fog all morning. Students went over data sheets and thought about how easy it would be to run statistical tests on data collected and how easy it would be to turn into an excel spreadsheet.
We also made a list of science goals. Analyzing our data sheets were at the top of the list followed by behavior recognition improvement, ID the whales from yesterday, practice hydrophone deployment, read the journal article for journal club and possibly deploy the Vemco acoustic tag receiver.
At around noon the fog finally cleared out and we had a quick lesson on sailing and how the boat moves using the wind and then we went out to practice.
After sailing in about 20 knot winds for an hour or two we came back to Mitchell Bay. We continued our sailing lesson and went over terminology and ended the day with learning how to tie knots.
In the evening we read the journal article for our journal club discussion and tried to identify the transients we saw yesterday. We positively identified T40 but could only identify one female, T37b.
We need an updated transient ID guide because the guide only has photos of the left side of the saddle patch and most of our pictures were of the right side.

Watching transients under sail (credit: Jeanne Hyde)
Today my classmates and I were heading into Mitchell Bay after our first full day at sea when our Captain, Todd Shuster, noticed a collection of whale watching boats off in the distance. We took the opportunity to turn around and were rewarded by seeing a group of transient killer whales by Sidney Island. There was one male orca, which we later identified as T40, with four females or juveniles. We have not identified the other four whales yet. Males are typically easier to identify because they have larger dorsal fins, but T40 is especially easy to pick out because the tip of his dorsal fin is bent over.
It was a very exciting hour watching the whales and the boats around them. A few times the whales took a view of the world above them by spy hopping and jumped into the air a couple of times as well. After the initial exhilaration, we began to confer about the behavioral state of the whales. We were unable to deploy the hydrophones in time to record any sounds. It was a good learning experience to enable us to be more proficient in organizing equipment so that next time we come across whales we will be able to record all forms of data. I feel fortunate that on our first full day at sea we came across orcas.

Jones Island to whales to Snug Harbor
Students raised the main sail for the first time on the Green Gato, and we sailed slowly from Jones Island to the beginning of Spieden channel. There the wind died, so we started motoring to Roche Harbor, where Val sped off to shore in the dinghy. We continued motoring towards Mitchell Bay and caught the wind for a while. When Todd noticed a little cluster of whale watching boats in Canada, we motored over to check it out. There they were — orcas — on the first full day at sea! Wahoo!
The whales we encountered were transients (the male T40 with four females) and they were frolicking and porpoising with glee. We stayed with them for about an hour, recording behavior and boat numbers. They started traveling north and we lost ’em. We motored back to Mitchell Bay, deploying the hydrophone as a demo on the way. We moored in the sunshine for an evening of swimming, burritos, and Grimm fairytales. -hmm.

FHL to Jones Island
OK, we didn’t discover giant squid, but the students did get a chance at the helm of the Gato Verde. The students were very efficient in moving all of the gear and food out of S1 and onto the Gato Verde so that we made a good start from FHL. We even got a chance to see Anne Harmon one of our students from 2007 on the dock at FHL. She is now working for Kwiaht, the Center for Historical Ecology of the Salish Sea. The journey was a smooth one under partly cloudy skies. Transited under electric power and tied up easily to the mooring bouy on the south end of Jones.

Today Val and Scott re-deployed a Vemco VR2 fish tag receiver at Lime Kiln State Park. This receiver, provided for this pilot study to Beam Reach by Fred Goetz, will help marine scientists understand how juvenile and adult salmon use the San Juans, in addition to any other passing fish that have been “tagged” (surgically-implanted) with 69 kHz acoustic tags. We at Beam Reach are most interested in the behavior and distribution of adult Chinook salmon, and secondarily any other potential prey of the endangered southern resident killer whales.

The photos above show the mooring prior to being snorkeled down to the pier block that remained from the previous deployment (last November).
Two other VR2s have been provided by Kurt Fresh of NOAA. (Their serial numbers are: 100910; 100913.) One will be deployed on the west side of San Juan Island; the other will be placed near Cattle Pass.  We’ve mounted them on short (~2.25m) mooring lines (1.25cm diameter 3-strand poly), supported by single yellow shrimp pot floats (see below). The base of the receivers will be ~0.75-1m above the bottom. The floats will be ~1m above the top of the receivers. The mooring weights are either ~25kg concrete slabs (35cm x 35 cm x 15 cm; see below) or paint buckets filled with cement. Both types of weights have metal hoops or chain for attaching the mooring line and for lowering during deployments from a boat.
Data and analysis from these deployments will be documented in the Beam Reach science wiki

As I’ve gone through the Beam Reach program, I’ve subconsciously looked for the one thread weaving each part of the experience together. As redundant as it seems, the truest thread I’ve found is connection.
The first time I consciously thought about connections during the program was while listening to Paul Coltrell during our first day at the Southern Resident Killer Whale (SRKW) Transboundary Naturalist Workshop. He was acting as a representative of Fisheries and Oceans Canada and explaining the steps that the Canadian government had taken to protect killer whales. Something about his explanation made me consider, more fully, the difference between transient killer whales, those who prey on mammals and move in quieter and less stable social groups and resident killer whales, those who prey on fish and move in highly communicative and stable social groups.
Those first few connections sinking into place at the workshop.
It was the first day I truly felt my brain had gone into “Whale Zone,†the name I’ve given to the state of being I find myself in when questioning whales and research. One of things we learned during two days of an incredibly steep learning curve was that residents and transients very rarely associate. They have slight morphological differences, different behaviors, and different sources of food. How can two populations be so similar and also so different?
In my opinion, the difference between the residents and the transients is the demonstration of something geologists call ‘actualism.’ It’s the idea that everything that is happening now has already occurred somewhere in the world. It’s a great way to study things that happened millions of years ago because you can look at something happening now and say that it is happening the same way it would’ve then. In my mind, we are seeing the actualism of speciation, a connection between species forever cemented in time, originating from the one point.
Not all connections I’ve found at Beam Reach are so scientific in nature. Most of them are as personal as can be. Each of us has found different personal connections, friends, family, or strangers who know people we know, who can contribute to our research, whose experiences connect to each one of us in a comforting and strange way.
Jason was trying to explain the name of the street he lives on, a vernacular word for someone ferocious. He couldn’t think of the word jargon and so instead, used the French word ‘patois.’ He didn’t notice he had used it but I was thrilled to hear it. That one word prompted a new connection, a realization that there was someone here who spoke French. I asked him how he learned his French and he explained a bit. We had been talking for a few moments before we realized that we were still speaking French and that no one else in the room could understand a word.
Jason and Val, who bring their own unique connections
The more I look back, the more I think about the connections weaving through all parts of this course, not just through me but through my family, my school or my friends. My dad did an independent study for Val in college on wood waste. The bike I’ve been riding here was brought to me by a complete stranger, transferring an act of kindness he once received and then safeguarded by Scott, prior to my arrival.
I am infinitely grateful to be reminded of the depth of connection between everything in our world. What could be more appropriate to be reminded of in a program about the survival of a population and the changes necessary to make our society sustainable.

Wolf Hollow
The morning of Wednesday April 15th, Erica, Hilary and I volunteered at Wolf Hollow Wildlife Rehab Center. Wolf Hollow is a non-profit organization that spreads awareness of wildlife on San Juan Island and rehabilitate injured animals with the goal of releasing them back into the wild. The majority of our time that morning was spent helping with the completion of the new Eagle Flight Enclosure.  The previous enclosure had been crushed under the weight of a heavy snow in 2006. We spread mulch around the facility and then continued to remove nails from the lumber of the destroyed enclosure. Erica and Hilary continued to help with the enclosure by painting the doors of the building while I moved to the front of the property and mowed the lawn surrounding the office buildings.
   Since it is still early spring, there weren’t many animals to see being rehabilitated, but it was pretty neat to see the infrastructure of organization. The commited people of Wolf Hollow spend a lot of time working to sustain the ecosystem of the island. Most of the animals they deal with obtain their injuries because of humans. This can occur when animals get struck by cars, or due to a loss of habitat with human expansion. Living on an island allows you to see your impact on the environment a lot easier than in ordinary conditions. Wolf Hollow does a great job helping others be aware of their impact on the ecosystem.

Hilary and I hard at work
Friday Harbor and the San Juan community is giving so much to the Beam Reach students. We are being housed, fed, and learning so much. It’s only fair for us to try and give something back to the community. Yesterday, April 15th, Hilary, Matt and I volunteered at Wolf Hollow Wildlife Rehabilitation Center. Wolf Hollow rehabilitates injured or orphaned wildlife with the goal of releasing them back into the wild. They also put a lot of emphasis on public education about the importance of wildlife and their habitat. They house many different animals throughout the year including river otters, seals, deer, numerous kinds of birds and other animals found on the island.
One of Wolf Hollow’s current projects has been rebuilding the Eagle Flight Enclosure. The previous flight enclosure collapsed in winter of 2006 from heavy snow. Now the new design is almost finished! The three of us spent all morning helping prepare the new structure for it’s grand opening this coming Saturday, April 18th.
We started out the morning raking a mulch path alongside the enclosure for people to walk on. The ground was still pretty muddy from all of the construction and the mulch path will make it much easier for people to walk along the new facility on Saturday. When we were done with that we removed the old nails from the wood that used to make up the old structure before it collapsed. We removed all of the nails and stacked the wood in another area on the lot to possibly be utilized again. Then Hilary and I painted the doors of the enclosure while Matt mowed the lawn in front of Wolf Hollow.
I really enjoyed my morning at Wolf Hollow and look forward to volunteering for another morning later in the quarter. For more information about Wolf Hollow and more details on what they do you can visit their website. http://www.wolfhollowwildlife.org/
