Scientists have used detailed high-resolution satellite images provided by Maxar Technologies' DigitalGlobe, to detect, count and describe four different species of whales. Reported this week in the journal Marine Mammal Science, this study is a big step towards developing a cost-effective method to study whales in remote and inaccessible places, that will help scientists to monitor population changes and understand their behaviour.
PIRatE Lab's insight:
This is an awesome approach to counting hard to find and widely distributed critters.

The world geeked out this past month over a 100-year-old box of negatives recovered in Antarctica. And with good reason — they contain never-before-seen images from the 1914-1917 Ross Sea Party, which was stranded while setting up supply depots for Ernest Shackleton’s expeditions.

Global Post has a nice compilation of (mostly) oceanic bottles cast adrift and the story of folks finding them:

Right now, a science expedition to Antarctica is trapped in ice, waiting to be freed so they can continue exploring. They're just the latest group of humans to venture into the unpredictable, frozen world of the South Pole and beyond.
PIRatE Lab's insight:
A trove of absolutely super cool historic images of the Arctic and Antarctic, many taken more than a century ago.

Cool show, focused on ice diving in Antarctica and our old friend Norbert Wu's most recent trip to use HD video to document subsurface antarctic environments.
Some great imagery here!
