Sleeper Shark Science 2020

My forearms were starting to burn as hand over hand I pulled in the 950ft of line from the depths of Resurrection Bay. The first 3 lines we pulled in were empty, save for the salmon heads we used as bait, but this one sounded different. The whir of the hauler was a bit louder, […]

Sunset on Shark Season 2019

We had our last day sharking on this past Sunday, but no weekend sharks were to be found. So as we pack up the totes of line, buoys and gear— it looks like it’s a wrap for shark season 2019! And what a season it was!   Our team spent over 30 days on the […]

Live slow and prosper

I shivered as my legs slipped beneath the 42⁰F water; everyone was up to their thighs in the cold water for our first day of metabolic trials with the Pacific sleeper shark. Even with waders on, I could feel the chill in my toes. Angelica handed me a large red plastic board and I carefully […]

Operation Sleeper Keeper

“Straight ahead!” Dr. Horning called out to the crew, taking his binoculars down and smiling. We had been gently bobbing south down Resurrection Bay for the last 40min, listening for the soft beep of the goniometer to confirm we were getting closer to our target—a miniPAT tag that had detached from a Pacific Sleeper Shark […]

Needle in a haystack

Back 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 […]

Sleeper Shark Season Wrap-up

Lessons learned and new horizons Well our first season of researching sharks is wrapped up! It has been a roller coaster and an example of teamwork in action. Since our first efforts at camera deployment and attempts at fishing, we have logged over 20 days on the water, from 3 different boats, and with a […]

It’s a shark!

To wrap up Shark week, we will continue the story of our Pacific sleeper shark research project. Now where did we leave off…? “It’s a shark!” Everyone clambered to the side of the boat to lean over and get a look. Sure enough, on our last hook of the day was a huge shark! Days […]

Here Sharky, Sharky, Sharky

A few weeks ago we posted about the surprising saga of the shark satellite tag scavenger hunt. Due to the unexpected nature of that occurrence, we actually got ahead of ourselves here on 60N on the story of the Sleeper Shark Research Project. Before the tag could be lost and then found–we first had to […]

Shark Tag Recovered!

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 […]

Murphy’s Law: A day on the water

It was one of those rare truly epic days in Resurrection Bay: sun shining, sparkling calm seas, endless snowcapped mountain views.  Our team assembled, and everyone was sipping the last of their coffees as the Jubatus, the ASLC research vessel, pulled out of the harbor. “Everyone ready?” I asked. When smiles and nods were returned, […]

Science “Rocks”!

Last week, we set out into Resurrection Bay on the ASLC research vessel Jubatus to test its new addition: an A-frame and winch system. The sturdy archway with hydraulic lift was outfitted to Jubatus to enable the deployment and retrieval of heavy moorings and equipment at sea, or in this case, some heavy rocks!

How we get research ideas

You’ve probably heard stories about how scientists get ideas that might include ‘it came to me in a dream!’. This blog post shares a different kind of story–one about how scientists take an idea, design a scientific study, discover an answer, and excitingly, end up with more questions!
