Internet access from the R/V Oceanus has been inconsistent, but education PI Tracy Crews has been able to send in some photos and observations via social media. Here are some of her observations, sprinkled with links to other blogs from other participants:
Day Two of our oceanographic cruise started with us once again surrounded by humpback whales feeding. In addition we have seen more seal lions and flocks of seabirds including some black footed albatross. Our teachers and students continue to shine as they deployed and retrieved another CTD (to measure Conductivity, Temperature and Depth) and collected and entered survey data into the computer on the fly bridge. Unfortunately, the weather turned overcast and chilly today forcing us all to bundle up.
Visit the GEMM lab blog to find out more about the marine mammals and birds encountered on Day Two.
Students and teachers have spent some of their downtime on the R/V Oceanus decorating styrofoam cups to send down to the bottom of the Pacific Ocean. Here are a couple of photos of the process.
Decorating the cups
The decorated cups were attached to the CTD that was about to be deployed.

We used two sizes of cups. This photo shows the difference in size before (center) and after (sides) the cups were sent to the deep ocean.

The styrofoam cups made it back from their journey to deep, 1400 meters to the sea floor attached to the CTD.
The sunset was a glorious ending to a great day. Although we didn’t see as many whales today as yesterday, we did see numerous humpbacks, a couple of fin whales, some Dalls porpoises, and some Pacific white-sided dolphins, as well as some sea lions, albatross, and ocean sunfish (mola-mola). We have left the waters off Heceta Head and will be making our way towards Astoria Canyon overnight. Sweet dreams to everyone aboard and on land!
