Read More Data in the blind spotIn our last post (click here if you missed it!), we chatted about tools scientists use to monitor and estimate wildlife population size. While we mentioned several techniques that can be used, we ended with the question: Can Argos satellite transmitter tags be used for electronic mark-resight studies? The short answer: probably yes. The long […]
Read More Can you hear me now?Electronic mark-resight studies: part 1 Aspiring young scientists often joke that they should put “expert counter” on their resume. Counting seals, counting barnacles in a quadrat, counting birds, counting cells… you name it, an intern has counted it. This is because a lot of ecological research and conservation requires knowing how many of something there […]

Not only did we learn what worked and what didn’t work in terms of sensor attachment and configuration, […]

Read More Question and AnswerWell, after an exciting summer of 2018 where we captured and worked with nine Pacific sleeper sharks here in Resurrection Bay, we are at it again for the summer of 2019. Our capture efforts are for a research project funded by the North Pacific Research Board. The project is carried out in collaboration with the […]
Read More We need a smaller shark (or a bigger boat)!This summer at the ASLC there is a new exhibit in town and it is all about science! As you walk past the model ship and across from Harbor Bottom, you notice a door. Last year in celebration of our 20th Anniversary, this room showcased our history and our mission. It reminded us of where […]
Read More Science on Exhibit!The anticipation I felt was more than I expected—every couple of hours I was logging into the Argos system database to check the latest satellite hits. Where were my seals going? Earlier that day: As a first-year graduate student in The Costa Lab at UC Santa Cruz, I was conducting my first field experiment with […]
Read More Translocations: science with some plot twistsWe had 5 days to prep 4 tags—should be doable, right? Add a couple extra pairs of hands to help and it should be a walk in the park…right? Maybe I should start with the fact that I had no experience refurbishing and prepping tags before the Tag Workshop hosted by Dr. Markus Horning at […]
Read More To build a tagBack in August we caught our 4th Pacific Sleeper shark. This animal was tagged with a Wildlife Computers mini-PAT (satellite pop-up tag) and then was released right off Caines Head in Resurrection Bay. The mini-PAT had been scheduled to detach itself 90 days after deployment, which was Monday. And right on schedule, on Monday, the tag […]

Read More It’s a shark!On May 31st, our ASLC Shark Research Team caught our first Pacific Sleeper Shark (we posted the picture of our success a few weeks ago here). As she was too big for our main study, we collected various measurements, samples, and attached a satellite tag to track her movements and diving patterns after release (Permit […]

His body was recovered floating in Morro Bay, California. As we previously reported, Otto was one of two southern sea otters recently taken to […]
