Hand deployed from a small skiff, Nanolander® DOV BEEBE, above, is photographed at a depth of 30m during testing off La Jolla, CA.  An expendable scrap iron anchor rests on the seafloor below the self-buoyant Nanolander.  A baited drop arm is deployed to the left.  (Photo above by Richard Walsh, Scripps Scientific Diving Program).
With data collected using a Global Ocean Design Nanolander®, DOV BEEBE, Scripps Institution of Oceanography PhD candidate Natalya Gallo successfully defended her dissertation “Influence of ocean deoxygenation on demersal fish communities: Lessons from upwelling margins and oxygen minimum zones”. This work involved numerous dives with DOV BEEBE totaling over 5 months of deployment.
Natalya said, “The Nanolander made it possible to study how seafloor communities respond to low oxygen events and how frequently these events occur naturally off Southern California.”
Assorted instruments populate DOV BEEBE’s payload bay, including a SeaBird Scientific SBE 37-SMP-ODO MicroCAT C-T-ODO (P) Recorder, an RBR-Global Duet3 CTD+DO+PAR (Photosynthetically Active Radiation), and a SubAqua Imaging self-recording video camera. Also onboard is a Scripps’ developed broadband acoustic recording system for benthic animal identification. DOV BEEBE is used to support research to depths of 1,000m.  An EdgeTech BART acoustic release inside the top sphere provides a dual release function on command from the recovery vessel.  The EdgeTech BART board offers up to 5 acoustic commands, yet fits inside a 10-inch sphere.
Dr. Gallo is continuing her work as a Scripps post-doc.

Phil Zerofski, Marine Technician with Scripps’ Marine Biology Research Division (MBRD), has experience with another Global Ocean Design Nanolander, DOV MUNK, in general marine science. A countdown timer release provided programmable deployment durations from 1 hour to 4 days. Phil captured excellent video of the Nanolander releasing its anchor and rising from the seafloor off California’s Catalina Island while testing the lander.  Phil says the addition of the Nanolanders to the Scripps fleet is a “game changer.”
A third Global Ocean Design Nanolander owned by Scripps, DOV JASON, is operated for Dr. Greg Rouse to study the progression of scavengers and predators that frequent a whale carcass sunk to the seafloor.  With an EdgeTech PORT LF-SD Release Transponder, the Nanolander can be deployed for up to 15 months in coastal environments.

Photo from the Field: Deck Purge Box in Greece

Matt Mulrennan of X-Prize spotted our Deck Purge Box in Greece and wrote, “Nice to see Global Ocean Design represented at the Shell Ocean Discovery XPRIZE field testing in Greece!”  The Deck Purge Box is our integrated vacuum/purge system.  With a universal power supply and no hazmat, it’s goes to work immediately upon arrival at its destination.
You can find more information on the Deck Purge Box here, and more information on the Shell Ocean Discovery XPRIZE field-testing here.
If you see one of our products in the field, please send us a photo, a brief description, your name and contact info.  We may include your photo in one of our next publications!
