DISCOVERY: New Tech Aids Understanding of the Oxygen Minimum Zone
oxygen in the core of the Southeast Pacific OMZ, leaving gaps in scientific knowledge on how this globally important ecosystem functions.The mTail device is a trace oxygen profiler that the scientists attached to a rosette, that carries Niskin bottles, and a mooring, standard pieces of oceanographic research equipment. Drs. Morten Larsen and Bo Thamdrup of the University of Southern Denmark developed the device alongside Dr. Laura Bristow of the University of Gothenburg, Sweden. Traditional sampling equipment for studying oxygen is relativelylow-resolution compared to the mTail, resulting in inaccurate
Allied Marine Crane Outfits R/V Neil Armstrong
The U.S. Navy’s research vessel Neil Armstrong (AGOR-27), scheduled for completion this year, is equipped with a modern array of oceanographic research equipment. To handle this equipment, Allied Marine Crane, a division of Allied Systems, Co., was chosen to design and manufacture two cranes, one A-frame, one davit, two handling systems and two hydraulic power units. Allied Marine Crane equipment was specified based on their history with research equipment handling, their proven design and build capabilities, and strong working relationship with marine winch supplier Markey Machinery.
