California’s red tide and glowing blue waves

Late summer algae blooms along the San Diego, California coastline have turned the ocean red during the day and a bioluminescent blue at night.
The fluorescent blue waves have attracted spectators to the shores around San Diego, offering rare photo and video opportunities.
It is interesting to note that the water is not constantly glowing, but only gives off a blue light when agitated, so the waves flash blue when crashing and then grow dark again.
From the Los Angeles Times:
The blue glow is caused by an algae bloom commonly referred to as a red tide. The organisms, phytoplankton called Lingulodinium polyedrum, have bloomed since late August, turning the water brownish-red in the daytime, according to UC San Diego scientists.
Check out this video of bioluminescent blue waves at San Diego’s La Jolla neighborhood.

Friend or foe: Invasive species in the UK
Minks and grey squirrels from North America, muntjac deer from China, red-necked wallabies from Australia – all have established themselves to varying degrees in different parts of the UK. These and many more are detailed in a new report by the People's Trust for Endangered Species entitled 'The State of Britain’s Mammals'. Some of the UK's invasive species have effectively 'gone native' and become part of local ecosystems. Others, like the American mink, are considered harmful to indigenous British wildlife. From an...
Black gold in Tinseltown: The surprising tale of Los Angeles’ oil fields
There are oil fields in Beverly Hills. In West Hollywood too, right under the famous Farmers Market. Despite L.A.'s fame for being a city driven by film and entertainment, it began principally as an oil town. From the late 19th century and into the present day, the Los Angeles metropolitan area, home to the third largest oil field in the contiguous United States, has had a flourishing oil industry. The enclave of Signal Hill, within the city of Long Beach,...
10:10 climate change campaign 6 months on: Saving money by helping the environment
The UK-based 10:10 global campaign was founded in September of 2009 by the director of the environmental documentary film The Age of Stupid, Franny Armstrong. The idea of 10:10 is simple – to cut greenhouse gas emissions by 10% in 2010. This means everyone, on both individual and organizational levels – businesses, schools, religious organizations, sports clubs, hospitals and people – wasting less and saving more. Even the UK’s new coalition government, along with 9 other governments, has signed on. To those...
The Hump Restaurant Permanently Closes Its Doors
A little over a week ago, it was reported that one famous California sushi restaurant was serving customers endangered whale meat. That restaurant has now closed its doors—permanently. The Hump restaurant of Santa Monica, California, was suspected of serving illegal whale meat to its customers. A couple of environmental activists did a bit of detective work and after doing some tests on a piece of whale sushi acquired from the restaurant, they discovered that the sushi actually came from the Sei...
The real Atlantis? Lost cities and lost continents
Terror Antiquus by Léon Bakst, 1908, State Russian Museum (public domain) The recent discovery of what might be a lost continent off the coast of Brazil has stoked imaginations and fascinated geologists. Granite formations some 1,500 km (950 miles) southeast of Rio de Janeiro may be remnants from a continent that sank when Africa and South America separated and the Atlantic Ocean was formed some 100 million years ago. From Euronews: According to geologists, as a result of tectonic movements, a land mass...
Britain grapples with nuclear power question as foreign radioactive waste is sent back whence it came
On Wednesday the UK began repatriating nuclear waste by shipping 28 half-ton canisters to Japan. The canisters are the first shipment of a cache of 925 tons of foreign radioactive atomic waste that will be returned to various countries of origin from Sellafield nuclear processing site – formerly known as Windscale – in west Cumbria. Besides Japan – Germany, Italy, Switzerland and the Netherlands will also be receiving shipments of the stuff during the ten-year repatriation process, according to an...
Breaking Down: Garbage Patch News
I recently wrote two articles on the Great Pacific Garbage Patch, which can be read here and here. I tried to balance them somewhere between informative news commentary and cynical emotional rant, the second article having a bit more of the latter, I guess. Still, I’m finding you can never get too much garbage in your patch, or plastic in your swirl, if you know what I mean. Wink-wink. In fact, as much as we’ve seen, heard or read about the...
Terra Nova: Apocalypse Dudes
Being an enthusiastic science fiction fan, when I saw there was a new post-apocalyptic/dystopian series on the way I was typically stoked. The involvement of Steven Spielberg and a couple of guys from the Star Trek franchise gave me moderately high hopes. However, Spielberg’s recent alien invasion series, Falling Skies, didn’t. I was weaned on low-budget sci-fi films and TV from the 80s, which in hindsight usually weren’t very good (see Cherry 2000 or Spacehunter: Adventures in the Forbidden Zone for...
28 Indian Rhinos Poached in the Last 11 Months Forces Investigations in Nepal
We live in a vast world with many different creatures. It may come as a surprise to learn where some species call home—especially when those places tend to be pretty remote and dangerous. Unfortunately, some of those dangers can still come from humans. In the past 11 months, 28 Indian Rhinos were poached throughout Nepal’s Himalayan Mountains. An investigation is currently underway as conservation officials, police and army chiefs were ordered to come up with a strategy to put a stop...
Green Gadgets: Nokia Unveils New Bike-Powered Phone Chargers
There are so many types of chargers out there that it’s become rather difficult to keep track of them all. You have your average wall plug-in chargers, solar chargers, manual/hand-crank chargers, hands free chargers, and bicycle chargers (among countless others). However, as far as the bicycle charger goes, I think this is the first time it has ever been used strictly for cell phone charging purposes. The Nokia Bicycle Charger Kit can charge your phone as you ride your bike. It...
