The ultimate goal of ADEON is to generate multi-year measurements of the natural and human factors that describe the ecology and soundscape of the U.S. east coast Outer Continental Shelf (OCS).  We aim to develop standardized tools for comparing soundscapes across regions and predictive models for the soundscape and overall ecology of the southeast OCS in water depths between 100-1000 m.

The Last Leg

Written by Carmen Lawrence, JASCO Applied Sciences Today we began the final leg of our month long voyage. We have come full circle and are now back at our first station, Virginia Canyon. Here, we retrieved the first lander deployed and deployed an 8th lander in its place. We did this to obtain a complete set of data to analyze and see what kind of data we collected in the month since it was deployed.

Close your eyes and picture the bottom of the ocean. What do you see?

Written by Brandyn Lucca, graduate student at Stony Brook University, New York. Is there a cornucopia of oddities and alien life that you’ve never see at the surface? Or do you see vast stretches of barren sand—devoid of life—which one could aptly describe as a moonscape? I can hear it now: “But Brandyn, it completely depends on where you are and at what depth!” That is true; however, unless we can filter every liter of water in the ocean, how can we discern the many biological differences at different depths around the world?

The wind is blowing Beaufort Six

Written by Calder Robinson, undergraduate at Dalhousie University, Halifax Nova Scotia. A half hour passes, another, nothing but wind, waves and whitecaps. The water is a grey green; empty of everything but phytoplankton, three ghostly shapes swim by, gone, just empty grey green water. I didn't quite believe it. I made a note and moved on. The end of my shift arrives, the lookout pointed forward silently, more of them, five or six lazily surfing the waves and diving them around the bow. Dolphins. We weren't really alone.

Fish with their own lighting brighten our researcher's night!

Written by Sebastian Velez. Photophores can also be used for defense. Many species like lanternfishes and hatchetfishes have photophores located in patterns along the underside of the fish. When these photophores activate they break up the silhouette of the fish making it more difficult to see from below where predators might be hiding. Living in the deep sea can be especially hazardous when considering the huge pressures and low temperatures these animals deal with on a constant basis, so it is all the more impressive seeing the adaptations they have evolved to cope with this extreme environment and become successful.

A Strangely Squishy Amphipod

Written by Hannah Blair, Stony Brook University graduate student.

The R/V Armstrong raced northward Monday, heading inland to Cape Hatteras to take some shelter from the bad weather and rough seas. On the way, though, we stopped at our Wilmington site early Tuesday morning to sneak in one last deep trawl (down to 1000 m). The trawl lasted over three hours, and we got some cool animals from it, including our second anglerfish of the trip and a very interesting large (and strangely squishy) amphipod, a type of crustacean.

Bye Bye Florida, back to winter we come!

Written by Jen Miksis-Olds. Bye Bye Florida, back to winter we come!  We all enjoyed the mostly calm seas and warm weather we found off of Florida.  Some of us prone to seasickness even decided that we might be able to survive out here without our seasickness meds.  Unfortunately that was rather short lived.  Now we are just trying to hold onto that taste of summer as we make our way rapidly back North to escape some possibly rough weather.  But this is exactly why bad weather days are built in when planning an oceanographic research cruise.  Though bad weather doesn’t sound good to those of us still getting our sea legs, we are just grateful that we were successful in reaching all of our deployment sites without any significant problems.

An ocean of larval and juvenile fish.

Written by Stephen Milea, Stony Brook University. This evening, we had the pleasure of catching many different larval and juvenile fish in our trawl.  Sebastian Velez (Graduate student at Florida Atlantic University) has been hard at work identifying all the species and continues to sit at the microscope as I type this blog.  According to him, we have a variety of reef and deep-sea fish including mahi-mahi, deepsea lizardfish, roughtongue bass, lane snapper, butterflyfish, squirrelfish, tilefish, cardinalfish, surgeonfish, anglerfish, and Sargassum filefish.

Water spouts and stickers!

Written by Carmen Lawrence, JASCO Applied Sciences. A true testament to being from Nova Scotia is a ceaseless ability to discuss the weather. Today, we had a lot to talk about. The day started out as a sunburn recipe, then dramatically changed gears to become copious amounts of rain. Then, on the horizon, we spotted an ominous sight! No less than three water spouts appeared several kilometers away! Then one began to form roughly one kilometer from us, but did not fully form.

Finding "Ada"!

This Ada blog and its photos is by Jennifer Miksis-Olds, School of Marine Science and Ocean Engineering, University of New Hampshire. Late this morning, the R/V Armstrong spotted a disabled autonomous surface vehicle far off the coast of Florida. Upon approach, the name of the vessel , Ada, was visible on the stern. We quickly learned from an internet search that this vessel was an autonomous sailboat from the University of British Columbia launched last year on a trip across the Atlantic.
