Microsoft co-founder's remote vehicles find a legendary WWII ship
The USS Indianapolis played an important role in WWII history, including the delivery of parts for the atomic bombs that would eventually drop on Japan. However, it met a grim fate: not only did a Japanese submarine sink it near the end of the war, but its wreck has remained elusive despite multiple expeditions over the past 72 years. Technology just provided some resolution, though. A team piloting Microsoft co-founder Paul Allen's research vessel, the R/V Petrel, has found the wreck of the Indianapolis at the bottom of the Philippine Sea. The discovery was helped by a mix of better information and the equipment aboard the Petrel itself.
Robotic vehicles find the Pacific Ocean's deepest thermal vents
Robotic underwater vehicles from the Monterey Bay Aquarium's Research Institute just helped discover one of the Earth's more elusive scientific treasures. Both an autonomous mapping craft and a remotely operated counterpart (which collected video and samples) traveled 12,500 feet to the bottom of Mexico's Pescadero Basin to find the Pacific's deepest hot hydrothermal vents. The machines achieved their feat in just two days, versus the years that it'd take for conventional undersea mapping -- and they achieved the kind of detail that would likely be difficult or impossible using those earlier techniques.
Drones help find World War II's missing soldiers
The BentProp Project has spent years finding American soldiers who went missing in the Pacific during World War II, but available technology has limited its success. Team members have frequently had to scan wide areas themselves, slowing down their efforts to find downed aircraft and unexploded bombs that might hide human remains. However, the outfit's searches have just taken a big step forward after it got cutting-edge drones from both the Scripps Institution of Oceanography and the University of Delaware. BentProp can now automate much of its scanning, and CNET notes that the organization's latest expedition found two Navy airplanes. That's a breakthrough for a group that only occasionally makes a big discovery.
Open source mini sub appeals to our inner Steve Zissou
Quadrocopters haven't exactly opened the skies for DIY exploration so much as they have for acrobatic feats, but the OpenROV project is hoping to make the briny depths friendlier for aspiring explorers and educators alike. The open source rover, spearheaded by NASA engineer and researcher Eric Stackpole, sinks to depths of up to 300 feet (100 meters), runs on eight C-cell batteries for approximately 1.5 hours and can clip by at three feet (one meter) per second. Within the laser-cut acrylic frame, a sealed cylinder houses a BeagleBone, HD webcam and LED lights. This all weighs in at 5.5 pounds and is piloted using a web browser and video feed. The footage is then piped up to a laptop that tethers the vehicle to the shore. Pre-orders for OpenROV 2.3 kits will be taken through Kickstarter later this summer at $750 apiece, though there are plans to sell fully assembled units. For now, explorers can register their interest at the link below and impatient Jacques Cousteaus will be pleased to know that all files necessary to build version 2.2 are available to download now.
Kongsberg Maritime intros underwater HD camera
Unfortunately, Kongsberg Maritime's oe14-502A is a far cry from being a traditional handycam wrapped up in a waterproof casing. Rather, this device was designed to latch onto remotely operated underwater vehicles (ROVs) and capture footage from the deep in glorious high-definition. More specifically, the inspection camera can capture at SD, 720p or 1080i (switchable via IR remote) and can handle PAL or NTSC. Of course, the standard model can "only" wander down some 4,500 meters before calling it quits (or imploding, whichever comes first), but that should be quite enough to grab some interesting undersea footage for pitching to Discovery.
Build your own underwater ROV for $250
Granted, this here project isn't nearly as inexpensive as the $100 underwater ROV from years back, but at least this one is propelled by something a bit more advanced than a pull string. Regardless, the ROV-in-a-Box Project Kit -- created by folks from Carl Hayden High School for use in the National Underwater Robotics Challenge -- is a $249.95 package that "includes all the parts needed to build a working underwater robot: a frame, motors, underwater light, camera, 50-foot tether, operator control box, and a dry-cell battery." Of course, you'll still be required to provide your own tools and TV monitor, but to take a closer look at exactly what a nickel under $250 will buy you, click on through for a detailed video (but do tap Mute beforehand, okay?).[Via GoRobotics]
Britain's Isis ROV set to trawl the depths of Antarctica
We've seen mechanical devices creep through the inside of intestines, huge mounds of dirt, and even through the San Francisco Bay, but now a British deep-diving remotely operated vehicle (ROV) is getting set to probe the depths of Antarctica. In hopes of uncovering more about the effects of glaciers on the ocean floor, as well as details about the living creatures that inhabit said areas, UK scientists are carting the machine aboard the RSS James Clark Ross as they head for the Marguerite Bay area on the west side of the Antarctic Peninsula. The robot, dubbed Isis, will spend time on its inaugural January mission combing the seabed and channeling live video and pictures back to its captains via the built-in cameras, lights, sonars for acoustic navigation / imaging, and two remotely-controlled manipulator arms. Once the bot gets dried off (and thawed out) from its arctic expedition, the next tour of duty is already lined up, as Isis will head off to the Portuguese coast to do a bit more sightseeing. Of course, if you're interested in taking the £4.5 million ($8.81 million) creature out for a mission you deem worthwhile, it should be available for deep-pocketed renters soon after.
