Familiar Flukes and Faces

Greetings fellow marine enthusiasts! My name is Cricket, and I am one of the interns working on Florence’s Gray Whale project! I’m preparing to graduate from Oregon State University in a couple of months with a Bachelors of Science in Biology with the marine option. Before I graduate, I wanted to get some extra experience in the field this summer, which is how I ended up here with Florence, Justin, and Sarah, having surprisingly crazy whale adventures along the Oregon coast!

Today marks the end of our first week in Port Orford. We weren’t sure what we were going to get when we switched sites, though of course we had a few fears: No whales, low visibility, bad weather, etc. Depoe Bay had been good to us so far, and we were slightly worried about the transition. In actuality, Port Orford has been amazing!

Day one was foggy, and we only visited the site briefly to figure out a good location for the theodolite. One of our sites is located on a terrifyingly high cliff, but the view is stellar. We were only there for about an hour and we saw two whales, one of which came up into the cove just beneath us. In fact, one of our concerns with this site is that the whales actually get too close to view through the theodolite. What an unexpected problem to have!

From our vantage point, we can get some incredible photos of these whales. Photo identification is a breeze if the whale decides to come into the cove closest to us. We can watch them under the water, as opposed to in Depoe Bay where we could only really observe them when they surface.

We all get particularly excited when we see the same whale more than once. In Depoe Bay, we had at least four different whales appear on multiple days. We can verify this using the photos we manage to get of the whales, and comparing them between days.

For example, in Port Orford, we spotted a whale on the 20th with a particularly large white spot on the fluke. This spot made the whale easily identifiable, so we were able to get a good focal follow (because we could track this whale amongst other whales with confidence that we were tracking the same one the entire time), which in turn allowed us to create a track line of this whale’s dive patterns. This whale happened to be whale sixty (the 60^th whale we’ve seen since the start of our data collection).

Then, days later, we spotted another whale. This was whale 78, and after a few surfaces, we realized this whale had the same white spot! We hesitantly referred to this whale as “sixty” but couldn’t be sure until we compared photos from the days before. And sure enough, it was!

I am particularly enthusiastic about our whale resights, and actively enjoy going through the photos and comparing each one to previous whales to try and identify individuals. It’s tedious, but rewarding when we can begin to learn individuals and identify them in the field. As a sort of rough guide to help us when scrounging through photo ID, I’ve put some of our good comparative photos into a google doc to use as reference. Here’s an example of some of the repeat whales we’ve seen:

Tomorrow will be day two at our second Port Orford site. Today was day one, and we managed to spot two whales, which is definitely promising. We hope we have as much luck finding and tracking whales there as we did on our cliffside!

Have a nice Gray!
