Hello from Madison on the R/V Endeavor!

The weather has been beautiful and in our favor. The water is becoming a little rougher as we make it up the coast. I was definitely feeling it yesterday morning. The sunsets are beautiful and different every day and I always look forward to seeing them. The other day we got to see a small pod of dolphins come along the boat. It was so cool and such a unique experience.

4am to 4pm with Andrew Heaney!

Hello, this is Andrew Heaney again; I last posted on this blog on June 7th. Quite a lot has happened since then; I have been working on both the day and night shifts, from 4 am to 4 pm. I can’t complain about the work itself nor the schedule. In the night shift, when Joe and the other night shift people deploy their nets, I help with writing down information on a clipboard and basically help everyone in the lab. The most interesting things we see, however, in my personal opinion at least, are the awesome little deep sea critters we catch in the nets!

Bandwing flyingfish and megalops-stage crab larva - Oh My!!

Hannah Blair Blog 14 June 2018

Hello again from the night shift. We completed our third night of zooplankton towing last night, and while retrieving the net were accompanied by an energetic school of bandwing flyingfish. Turns out they had good reason for their leaping and gliding above the surface of the water: a pod of rough-toothed dolphins emerged from the dark ocean around us, eagerly chasing after flying fish snacks. A couple of the flyingfish stranded themselves on deck, allowing us a closer look.

Sacrificial Anodes

Another lander was successfully picked up this morning, even with the extra waves at this site. The waves made it a little more difficult for the lander to be retrieved and required more people to help grab the lander from the water and get it on board. As we’ve been prepping the recovered landers for the next deployment, we’ve noticed that a lot of the corrosion on the hardware is just surface corrosion. This tends to come off the bolts and washers with a little water and some scrubbing with wire brushes. To prevent the hardware that is holding on sensors from corroding, we use anodes to protect those components.

On the night shift . . . .

Hello from Cassie Fries on the R/V Endeavor! Now fully acclimated to our night shift schedule, we work from 8pm to 8am doing everything from net tows with an IKMT horizontal net, vertical tows with a bongo net, sorting, animal identification, and even help out the day crew with lander retrieval when needed (when the sun comes up). Going to bed after breakfast and waking up around dinner time might sound hard, but when we’re this busy during the night it gets easy to switch your schedule to be nocturnal.

The ADEON webpage lander maps.

At daybreak, both the science and ship crew were happy to watch the second lander pop to the surface after spending the last 6 months sitting on the seafloor collecting data. After it was brought on board, a team of people started taking it a part to download data, replace batteries, remove/replace rusted hardware, and prep the lander to be deployed again. It is like a raceway pit crew descending upon the lander to get it ready for the next deployment just hours after it came on board. We are now on our way to the third ADEON location labelled CHB (Charleston Bump) on the ADEON webpage map (click on "read more" just below to get to the maps).

A Total Eclipse of the Parts .. .. .. .. and the mysterious disappearance of Sir Pings-alot.

Waiting to see if an instrument that you put 100s of meters below the sea surface six months ago is going to come back up when it should? think - - - Turnaround, every now and then I get a little bit lonely- And you're never coming round. Turnaround, every now and then I get a little bit nervous- That the best of all the acoustics have gone by. Turnaround, every now and then I get a little bit terrified- That there's nothing more from little AMAR .......

Artist on Board!

I’m Lindsay Olson, an artist with a science-based practice and will spend time on board the RV Endeavor learning the basics of ocean acoustics. What makes this cruise unique for me is that I’ll also be participating in the science. I’ve had the opportunity to work with teams deploying and recovering the CTD (water sampling gear), marine mammal observation, and other duties as needed.

Science that involves sampling out at sea relies upon a far-reaching network of collaborators.

My name is Katharine Coykendall. I work for USGS in Kearneysville, West Virginia. Our lab has a broad interest in the connections and relatedness between biological communities and as well as the biodiversity in marine ecosystems. We use genetics and genomics as tools to answer those types of questions, just like forensic crime labs and genealogical websites, but we are looking for connections between marine organisms.

The First Lander Retrieval!

Hello! I’m Carmen Lawrence, and equipment technician from Halifax, Nova Scotia. I work for JASCO Applied Sciences, a company that specializes in passive underwater acoustics. My primary role at JASCO is maintaining oceanographic equipment and preparing moorings for deployment at sea. Today was an exciting day, as we successfully retrieved the first lander and deployed the new lander in the same location. Everything went very smooth and according to plan - thanks to the professional crew aboard the R/V Endeavor.
