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 "Triplewart Seadevil" is aptly named.

Today’s blog is written by Chief Scientist Joe Warren (Stony Brook University). There is a friendly rivalry between the day and night shifts on the vessel. And while the day shift spends all day looking for deep water, the night shift is busy sending nets down to near the bottom of the ocean to sample the marine life that lives there. One of the biggest challenges that we have when flying a net is that (in many cases) it can be difficult to know how deep your net is in the water. We have meters on the ship's winches that tell us how many meters of wire have been put into the ocean, but since the ship is moving that wire isn't hanging straight down.

Searching for Deep Water!

Today's blog was written by ADEON lead PI, Jen Miksis-Olds.  Yesterday we deployed bottom lander #5 on the Blake Plateau in approximately 900 m of water.  The evening was spent doing net tows and fine scale acoustic surveys to get more information about the small marine life in the water.  During daylight hours, the day watch rotates through 90 min marine mammal observation (MMO) shifts. The MMO shifts have been a disappointment the past 2-3 days.

"Trash Can CSI" or How do you determine the acoustic profile of a Squid?

Today's  blog is written by Brandyn Lucca, a PhD student in the Acoustic Laboratory for Ecological Studies (ALES) at Stony Brook University. We use underwater acoustics for a variety of reasons such as bottom-mapping, listening for marine mammals, and figuring out where we want to fish on a Sunday morning. In my biased opinion, the best use of underwater acoustics is using it to count the critters in the water column to improve our understanding of animal behavior and ecological interactions as a function of space (e.g. from Virginia to Florida) and time (e.g. night versus day).

SPIRITed Seas: Inferring sea surface roughness with a custom-built sensor package by Calder Robinson

Today's blog is written by Calder Robinson, undergraduate student at Dalhousie University, Halifax, Nova Scotia, Canada. As a fourth year undergraduate honours student from Dalhousie University the opportunity to take part in an oceanographic cruise is pretty much unparalleled, it being the formative experience of the degree. Even more so, the opportunity to conduct your own experiments and collect your own data, using a sensor you designed and built is probably the best thing that can happen to a fourth year undergraduate in this field. It’s an incredible chance to learn from the variety of experts on the vessel, offering insights and tips to improve the scientific methods; not to mention answering all of my questions since they are on a 230’ boat and can’t run away for long. All of this happening while I take a trip from the cold north down to the warm sunny coasts of Florida? Life can’t get much better!

Learn about FAU graduate student Sebastian Velez and the ADEON sister project DEEP SEARCH!

Today’s blog is written by Sebastian Velez, MS graduate student at Florida Atlantic University. It is exciting to have Sebastian out sailing with ADEON because 1) it is extra hands to work up samples, and 2) Sebastian is a bridge between ADEON and a related sister National Oceanographic Partnership Program project called DEEP SEARCH.

What a glorious day at sea!

Today's Blog is by Kevin Heaney, from OASIS, the science team’s ocean acoustics guy....

Today marks the completion of our first full week at sea. The weather's been great (sea-state 2, small waves, light wind for today) and the cooks keep providing fresh salads, two veggies, and two main courses PLUS dessert for each meal.

The night watch crew had quite the enjoyable Thanksgiving on the R/V Armstrong.

Blog post by Hannah Blair, Stony Brook University graduate student.

The night watch crew had quite the enjoyable Thanksgiving on the R/V Armstrong, from finding squid in our trawl net (one of my favorite animal groups!) in the early hours of the morning, to a giant buffet in the galley for Thanksgiving dinner – or for us, Thanksgiving breakfast.

Takin' care of business!!

This post is by Hilary Kates-Varghese, UNH graduate student.

Takin’ care of business!! We now have two landers deployed in their new homes for the next 8 months. A successful and productive cruise thus far. This can likely be attributed to the fantastic crew helping us at all hours of the day and the delicious food we’ve been fueling on. Last night we celebrated Thanksgiving on the boat and we ate like kings and queens!

Today, we started the acoustic survey and the trawl survey.

This post by Steve Miles of Stony Brook University.

Today, we started the acoustic survey and the trawl survey. Despite incorrectly mounting the flow meter, the first trawl deployment was successful at a depth of 60 meters. Some of the more interesting animals included moray eel larvae, lobster larvae, flatfish larvae, mantis shrimp larvae, squid, deep-sea fish and a small fish with spines on its head with black and red spots that we could not yet identify.
