Canadian Waters Teem with Phytoplankton

In late August 2016, the waters off British Columbia, Canada, turned green. “Certainly unusual,” was how Jim Gower of Fisheries and Oceans Canada described it. “Unprecedented, in the sense that none of us have seen blooms this bright here before.”

For reasons that scientists are still trying to figure out, the Strait of Georgia and nearby inlets have been teeming with coccolithophores, a harmless type of phytoplankton, or floating plant-like organism. Coccolithophores have chalky, scale-like shells made of calcium carbonate. The milky-white color of those shells can brighten and discolor otherwise blue waters when the plankton explode in such massive blooms. Marine scientists believe some harmless species of diatoms are also in the mix, adding to the green color.

The Operational Land Imager on the Landsat 8 satellite acquired this image on August 19, 2016.

While coccolithophore blooms occasionally occur off the west coast of Vancouver Island, no one can recall seeing a bloom like this in the Strait of Georgia. The countless phytoplankton have spread into the surface waters of Howe Sound, Desolation Sound, and Malaspina Inlet, among other waterways. The main species found in most coccolithophore blooms, Emiliania huxleyi, is not harmful to fish or humans. The blooms tend to dissipate in a few weeks.

“No one knows why this bloom is so widespread and intense,” said Debby Ianson of Fisheries and Oceans Canada. She suspects that a seed population from the west may have been carried (by advection) into the Strait; coccolithophores are more common in the Alaskan Gyre and other offshore Pacific waters. The seeds that found their way from the continental shelf into the Strait would have encountered relatively low pH waters that are not necessarily good for phytoplankton growth.

Debora Iglesias–Rodriguez, a marine ecologist at University of California, Santa Barbara, noted that coccolithophore blooms have been occurring more often in places where they are not usually expected, particularly along the west coast of North America. For instance, there were blooms in Santa Barbara Channel and Monterey Bay in 2015 during the recent El Niño event. These phytoplankton are good competitors for resources and tend to grow well under low-nutrient conditions that can limit other species.

Recent research suggests that coccolithophore numbers have been increasing over the past two decades in the North Atlantic even though the water is growing more acidic. Iglesias-Rodriguez pointed to large recent blooms off the coasts of Delaware and Spain. Globally, the oceans are acidifying due to increasing carbon dioxide concentration in the atmosphere; the gas is exchanged with and absorbed by sea water.

Raspberry Pi 3 is on sale now at $35! It features a 1.2GHz 64-bit quad-core CPU, giving about 10x the performance of a Raspberry Pi 1, as well as wireless LAN and Bluetooth. It's completely compatible with Raspberry Pi 1 and 2.
Exactly four years ago, on 29 February 2012, we unleashed the original 256MB Raspberry Pi Model B on a largely unsuspecting world. Since then, we’ve shipped over eight million units, including three million units of Raspberry Pi 2, making us the UK’s all-time best-selling computer. The Raspberry Pi Foundation has grown from a handful of …

I really like the Pi, but they have to fix the "let's bus everything through the USB" problem. I'd like to see a proper bus with eSata and USB3. I honestly don't understand why the need to embed wireless into the device -- That's easily fixable by a USB dongle (as long as the Pi properly supports high amp devices in its USB ports, which the Rpi2 doesn't.)

The countdown has begun for blastoff of the ambitious European/Russian ExoMars 2016 spacecraft from the Baikonur Cosmodrome in Kazakhstan on March 14. Its goal is to search for minute signatures of methane gas that could possibly be an indication of life or of nonbiologic geologic processes ongoing today.

This Poster Beautifully Details Humankind's Many Space Explorations

With all of NASA's recent (and historical) explorations and achievements, it's only natural that the visualization masters over at Pop Chart Lab would decide to make a poster dedicated to humankind's expeditions into the final frontier. This stunningly detailed poster catalogs all of them—from Luna 2 in 1959 to DSCOVR in 2015. There are over 100 exploratory devices featured, from orbiters to rovers to landers. The color-coded poster traces the path each craft took on its trip through space, weaving a delightful web. Planets, moons, asteroids, and even Pluto appear as points of interest for the cosmic explorers.

This comprehensive guide of the solar system shows where all the exploratory instruments have been.

Euro vision for the world's largest radio telescope

You might have heard about the Square Kilometre Array, and how it will transform the way we understand the Universe, but have you ever stopped to think what it takes to build the world’s largest radio telescope?

“Building a telescope at such a remote location is a huge logistical challenge,” explains Ant Schinckel, who heads up the SKA Infrastructure Australia team (and is also the Project Director of our newest telescope, ASKAP).

“There’s power, communications, water supply and sanitation to consider, as well as somewhere to put the supercomputer and complex digital electronics. Ultimately, everything we design needs to preserve the radio-quiet environment of the site to ensure the SKA will answer some of our biggest questions.”

The SKA will be co-hosted by Australia and southern Africa, and our site – the Murchison Radio-astronomy Observatory – is located in the middle of the outback in Western Australia. This location was chosen specifically because it is far from the electronic hustle-bustle of the everyday world, and therefore extremely “radio quiet”.

This could be huge. The human race needs to become interplanetary ASAP... somewhere out there, there's a big Extinction Event with Earth's name on it...
