This is the first report from this year’s expedition to Cashes Ledge with Brian Skerry and Brown University biologist Jon Witman. I’m accompanying the team and reporting from Cashes. Follow the expedition on Twitter for regular updates!
After departing Boston, MA, around 2pm yesterday, our research vessel slowly made its way to Cashes Ledge, arriving in the early dawn.
Let me just say, you don’t have to go below the waves to know that Cashes Ledge is full of life. We spent the morning watching humpback whales feed on schools of fish, while seabirds circled and dived from above. All day the whales continued to surface, so close to the ship that we could hear their spout from on deck.
The waters were fairly calm today and the team was able to complete two dives, the first around 10am and the second around 2pm. The fog rolled in just as the second dive began and has stayed with us. The visibility underwater was low, but the team saw plenty of fish – mainly cod, pollock, and cunner. After the first dive, Brian Skerry reported that the kelp is healthy, thick, and lush, and Dr. Jon Witman described it as “very luxurious.”
While the team was underwater, I assisted Dr. Witman’s undergraduate assistant Fiona Beltram as she measured the kelp samples collected by the scientists from Ammen Rock. Among the kelp, we found beautiful sea stars, baby brittle stars, horse mussels, and encrusting bryozoans. Don’t worry, all the samples are being returned to the sea.
As Jon and Fiona finish measuring their kelp samples, the rest of the team is relaxing (some napping) after a busy first day.
