BlueGreen: Our Connection to the Ocean

Monday, October 4th, 2010

In an effort to help spread the word for independent filmmakers with an environmental slant, here’s a post about BlueGreen - a film that explores the human connection to the ocean.

Featuring some of the world’s most talented surfers, including Keith Malloy and 7-time Women’s World Champion, Layne Beachely, combined with footage shot around the world, BlueGreen examines the connection between humans and the ocean and explores this connection through thoughtful insight from scientist, activists, athletes and enthusiast. From the physiological to the spiritual, filmmaker and surfer, Ben Keller explores the power of the ocean and how it affects our lives and why we are all attracted to it in one way or another.

“Blue green is a surf film, yes. But it is more than that. It is an exploration of our ties to the ocean – beyond the obvious” explains Cinema Libre Studio, the distributor for BlueGreen.

“Of course, if you are going to expound upon the human connection to the ocean, you can’t really avoid an environmental message. You bump right up against it. So the film explores that as well, from how the surf industry affects it to what we as people need to consider.”

According to the BlueGreen press release, “There is an environmental message that Keller pays special attention to - in light of the rise in the man-made pollution (i.e. Deepwater Horizon oil spill) - and he believes there is a fundamental lack of understanding and knowledge of just how important a role the ocean plays in our daily lives and hopes a better understanding will lead to its protection”.

BlueGreen: Our Connection to the Ocean is now available on DVD.

New Species of Bamboo Coral Found in Deep Sea

Marine biologists have discovered a new species of coral growing on the peaks of seamounts off the coast of the Pacific Northwest.

The fan-like bamboo corals, discovered at depths of 700 to 1,000 meters (2,300 to 3,300 feet), were found to be growing to more than a meter tall. 

“They look really, really big when you’re underwater,” said marine biologist Peter Etnoyer of Texas A & M University.

According to Discovery News, the new species will be described and given a name in the upcoming December issue of Proceedings of the Biological Society of Washington.

Although the species is new to science, fragments of the bamboo coral have landed in the nets of fishing trawlers for years. 

The scientists observed the new coral species from Alvin - a deep-sea research vessel. From Alvin, they were able to observe long tentacles on its trunk billowing in the current. Etnoyer commented that this impressive sight is something that can only be seen and appreciated by looking at a living specimen.

Bamboo corals, which are part of the Isidella  genus, provide deep sea creatures with food, shelter, and a breeding ground.

About Deep Sea Corals

As the name suggests, deep sea corals are corals that live in deep seas. 

Most deep sea coral are found between 200 and 1500 metres deep but some species have been found more than 3000 metres deep. At these depths, it is usually pitch black and the water is very cold (usually between 4°c and 12°c degrees).  

Deep sea corals are found in the Atlantic, Mediterranean, Indian and Pacific Oceans.

Unlike tropical corals that can grow up to 100–200 millimetres per year, deep sea corals grow very slowly. Some deep sea corals are known to grow at a rate of 4–25 millimetres per year.

About two thirds of all coral species are deep sea corals.

Deep sea corals were first discovered in the 18th century but, until recently, very little has been known about them. Recent advances in technology is starting to change that though, particularly with deep water trawling, advanced imaging systems, submersibles (such as Alvin), and advanced acoustic seafloor mapping systems.

What is a Cay?

Wednesday, April 2nd, 2008

A cay is a small, low elevation, sandy island formed on the surface of coral reefs. Cay is pronounced as ‘key’ and is sometimes spelled key or quay.

Cays are typically located in tropical waters such as the tropical parts of the Pacific Ocean, Indian Ocean, and Atlantic Ocean. For example, there are many cays throughout the Great Barrier Reef - the largest coral reef in the world. Some popular cays in the area include Green Island, Michaelmas Cay, Upolu Cay, and Heron Island.

Cays are mostly made up of biogenic sediment from coral reef ecosystems. Biogenic sediment refers to the skeletal remains of plants and animals. Ocean currents transport the sediment across the reef surface, then deposit it in a place where currents converge or slow down. Weather and tidal patterns can impact on the formation and eradication of cays.

Some of the smaller cays often appear to be no more than a sandbar, while larger or older cays will have trees and other foliage growing on them.

The World’s Largest Garbage Dump

Tuesday, March 25th, 2008

World's largest garbage dumpIf I told you the world’s largest garbage dump was almost twice the size of continental United States would you believe me?

Well, that’s how big the Great Pacific Garbage Patch is. The Great Pacific Garbage Patch is the collective name for two gigantic masses of garbage floating in the Pacific Ocean. The two masses are known as the Western Pacific Garbage Patch and the Eastern Pacific Garbage Patch.

The Great Pacific Garbage Patch has been described as a “plastic soup”. It consists of about 100 million tons of garbage, extending up to 100 feet below the surface, all being held together by the swirling currents of the ocean. The mammoth garbage patch is a result of general litter from both sea vessels and land. Here’s an animation showing the movement of the currents surrounding the Great Pacific Garbage Patch.

Curtis Ebbesmeyer, an oceanographer, has compared it to a living entity, “moving around like a big animal without a leash”. Ebbesmeyer, who has tracked the build-up of plastics in the seas for more than 15 years, says that when the animal comes close to land “…the garbage patch barfs, and you get a beach covered with this confetti of plastic”. Some beaches in Hawaii have been known to be buried in 10 feet of plastic garbage!

The Great Pacific Garbage Patch was discovered in 1997 by Charles Moore, an American oceanographer. He came across it by chance while taking a short cut home from a Los Angeles to Hawaii yacht race. After steering into the North Pacific gyre, he found himself surrounded by garbage. Not just a little bit of garbage, but a virtual continent of garbage. All day, every day, for about a week, his vessel sailed through a sea of garbage. Moore said “Every time I came on deck, there was trash floating by”.

Following this alarming discovery, Moore sold his oil business and became an environmental activist.

What’s being done about it?

Unfortunately, many scientists believe that it’s pretty much impossible to clean up the Great Pacific Garbage Patch. They have also said that attempts to do so could actually do more harm to plankton and other marine life. In any case, the US government recently passed legislation to increase funding so that more clean up work can be done.

Giant Sea Creatures Found in Antarctic Sea

Saturday, March 22nd, 2008

Researchers have discovered giant marine life in the seas of the Antarctic.

The discovery was made during a 50 day voyage in the Ross Sea. New Zealand Marine Scientist, Don Robertson said that they found “Huge sea snails, jellyfish with tentacles up to four metres long and starfish the size of big food platters”.

The voyage, which covered 3,200 km, resulted in 30,000 specimens, making it the most comprehensive survey to date. Among the specimens, were about 90 different species of fish, eight of which could be a previously undiscovered species. There are at least eight new molluscs and a range of new invertebrates too. Analysis of all 30,000 specimens could take up to two years.

The survey covered all levels of the water, from the surface to the sea floor - 3,500 meters deep.

The survey is part of the International Polar Year program, which involves 23 countries and 10 other voyages around the Antarctic. The voyages will continue until July 2009.
