New NOAA report examines national oil pollution threat from shipwrecks

New NOAA report examines national oil pollution threat from shipwrecks
These are just the kinds of scenarios that an AUV based monitoring program is ideally well suited for and I'm not just speaking as an interested AUV party someone needs to do this.

New NOAA report examines national oil pollution threat from shipwrecks

NOAA presented to the U.S. Coast Guard today a new report that finds that 36 sunken vessels scattered across the U.S. seafloor could pose an oil pollution threat to the nation's coastal marine resources.

How underwater Street View works

How underwater Street View works
Google Earth Blog

Last September we showed you the first set of amazing underwater Street View images that Google had released.  They were absolutely stunning, as you can see in the example here:


TechCrunch recently spoke with Google about their Ocean Street View program, and came away with some amazing insights, including:

…the cameras his team uses for this project are very different from those used by Google's other Street View vehicles. The team had to use wider-angle lenses, for example. Google's underwater Street View camera has three cameras on its front and takes images every three seconds. One of the cameras points downward, because that's how images during reef surveys have traditionally been taken. The back of the scooter features a tablet that can control the cameras.

During a typical dive, the divers cover about 2km and take 3,000 to 4,000 images per camera, and the team does three dives per day, each of which lasts about an hour. In total, the team has taken about 150,000 images so far, and Vevers expects this number to grow exponentially over the next few months. In the long run, the team hopes to create diver-less systems that can stay underwater for 12 hours or more. The technology is already available, but it needs to be adapted to the kind of camera system needed for Street View.

The systems cost around $50,000 each, and they're already testing 3D cameras to begin to capture that kind of imagery soon.


It's quite an amazing article, and it offers some great details into how this system works.  Check out the full article, then explore our previous post on underwater Street View to visit some of these areas for yourself.

Observed Atmospheric CO2 Hits 400 Parts Per Million

Observed Atmospheric CO2 Hits 400 Parts Per Million

symbolset writes "Over the past month a number of individual observations of CO2 at the Mauna Loa Observatory have exceeded 400 parts per million. The daily average observation has crept above 399 ppm, and as annually the peak is typically in mid-May it seems likely the daily observation will break the 400 ppm milestone within a few days. This measure of potent greenhouse gas in the atmosphere should spark renewed discussion about the use of fossil fuels. For the past few decades the annual peak becomes the annual average two or three years later, and the annual minimum after two or three years more."
