1st High Seas Marine Protected Area in Southern Ocean — More Diverse than Galapagos Islands

Zachary Shahan — Tue, 24 Nov 2009 21:45:21 +0000

Fishing and refuse disposal are to be banned in the 1st high seas Marine Protected Area (MPA) in the Southern Ocean, an area of the ocean that contains more species than the Galapagos Islands.

This will allow scientists to monitor the effects of climate change in this region. This is only the first of possibly twelve such areas.

Wave Energy Looking for Breakthrough — Using Aerospace Design

Zachary Shahan — Sat, 21 Nov 2009 18:27:49 +0000

The oceans seem like a great potential source for clean energy. The force of the waves, the constancy, the size of the oceans — it all seems like something that could produce energy for humans without much harm. (I still have some concerns, though it seems like one of the best options these days). Some of the major problems with utilizing the force of the oceans, however, have been how to survive storms, the need to be anchored to the see floor, and efficiency.

Researchers from the US Air Force Academy have a new, outside-the-box idea for dealing with these problems — use an aerospace approach.

This is yet to be developed to full-scale and tested in that form, but early computer and model-scale tests are showing higher efficiencies than wind turbines, according to the National Science Foundation (NSF).

Scientists Developing Swarms of Miniature Drifting Robots to Patrol the Ocean

Tina Casey — Sat, 21 Nov 2009 17:14:06 +0000

The National Science Foundation has just awarded researchers at UC San Diego a $1million grant to develop small robotic devices that will drift with the ocean currents to study the mechanisms that support plankton and other tiny marine creatures. Swarms of the autonomous underwater explorers (AUE’s) could provide a window into the underlying factors that drive broader ocean processes, by more precisely focusing on localized data on currents, temperature, salinity, pressure, and other properties.

The robots could also some day patrol and monitor protected marine areas, provide early warnings of potential hazards such as algae blooms and oil spills, and even scout out plane crashes and other ocean-going emergencies. Depending on how the devices are powered, the robot swarms could also provide a more sustainable means of accomplishing oceanic research compared to the use of ships and other fossil fuel-powered equipment.

Oceans’ Ability to Absorb Carbon & Protect Against Climate Change Weakening

Zachary Shahan — Fri, 20 Nov 2009 23:23:03 +0000

Oceans regulate our climate. They play a key role in keeping the world’s “homeostasis” in tact. However, their ability to absorb carbon & keep the climate in balance is dwindling, a new report shows.

In a year-by-year study from 1765 to 2008, researchers found that the oceans are struggling to meet increasing emissions demands. They cannot take in as much carbon as they used to.

The study, published in the November 19 issue of the journal Nature, found that the percentage of fossil fuel emissions the ocean has been taking in since 2000 has decreased by as much as 10%.

This is the first study of its kind or breadth. One previous study had attempted to measure the oceans’ industrial carbon absorption for one year — 1994. This does so for a period of 200+ years.

See a Battery, Pick It Up

Rhonda Winter — Fri, 06 Nov 2009 22:08:07 +0000

See a battery, pick it up, and all the day you’ll have good luck. Especially if you take the battery that you found and safely recycle it, keeping dangerous toxic poisons out of our seas and drinking water.

I found this used battery near the ocean in Pacifica, right across from our friend Rick’s Salada Beach Cafe. It has since been safely recycled, and kept from polluting our waterways.

Our oceans are already turning into acid. We have to start today to try to make things better. Keeping one more toxic battery or piece of plastic out of our oceans, collectively, will make a difference. Once you start looking, you may be really surprised just how many “disposable” batteries litter our streets and sewers. Next time you see one, pick it up; what you do matters.

A Passion for Fish and the Planet: Passionfish Restaurant

John Ivanko — Wed, 04 Nov 2009 22:21:54 +0000

Some people say you eat with our eyes. At Passionfish restaurant in Pacific Grove, California, you do so with your heart — at a place where the local is celebrated, showcased, and conserved. Sometimes, savoring a meal can nurture our body while helping preserve or restore the planet. One day, every meal will be consumed this way.

While my family and I make every effort to eat local and lower on the food chain – mostly vegetarian – when we travel, we occasionally become “flexitarians” and enjoy a seafood dish or two when we’re at the edge of a vast ocean, perhaps with a wharf at the end of the street. At Passionfish, a restaurant nestled in the scenic Monterey Peninsula just a mile from the Monterey Bay Aquarium, we connected with the Pacific Ocean by both its salty breeze and through the food we savored.

Opening in 1997, Passionfish is the brainchild of Chef Ted Walter and his wife Cindy Walter. Besides being restaurateurs, the Walters’ might as well be called “marine activists.” This dynamic duo have ambitions of changing the world by educating people about what they eat, especially if what they eat comes from the sea. Using their restaurant as the alluring (and delicious) platform, the couple promotes sustainable seafood as well as locally sourced, fresh, organic vegetables and fruits. Even their meat products are pasture-raised.

Our Oceans Are Turning into Acid

Rhonda Winter — Mon, 26 Oct 2009 23:59:16 +0000

Sigourney Weaver narrates “Acid Test“, an illuminating and terrifying NRDC documentary that explains how quickly our planet’s oceans are acidifying due to all of the carbon dioxide that we are pumping into our air. This pollution is causing rapid changes in our oceans’ chemistry that will completely disrupt all life on the planet as we know it on a scale that has not been seen for tens of millions of years.

An Ocean of Effort

Dave Dempsey — Sun, 25 Oct 2009 20:59:36 +0000

Ocean trash is one of the problems photographed by Christopher Swain on his 1,000-mile ocean advocacy and education journey.

As the Obama Administration’s Interagency Ocean Policy Task Force moves into its sixth public meeting on an interim report in Cleveland this week, one determined ocean advocate is continuing to make his way from Massachusetts to Washington, D.C, in part to dramatize his concern about the state of the seas.

Christopher Swain’s 1000-mile swim, which includes frequent stops along the way to educate students and to do sampling, was born out of a childhood connection to the sea growing up in Massachusetts. He says the journey will take about 200 days of swimming over two years — and will continue off-and-on through the winter.

The Growing Coral Craft Project to Save Endangered Sea Coral

Lucille Chi — Sun, 20 Sep 2009 19:04:18 +0000

Upon window gazing in San Francisco, this immense coral yarn sculpture reminded me of one of the most unique, and unusual TED Talks I’ve ever seen and it’s about coral yarn crochet. In this TED (Technology and Entertainment Design) talk, Margaret Wertheim shares the coral project she started with her twin sister that is all about crocheting the coral reef.

The idea of this yarn filled coral sculpture garden is inspired by endangered sea coral, the ancient art of domestic handicrafts, and the new discoveries in mathematics by Dr. Daina Taimina on the beautiful math of coral.

3 New Species Found in Underwater Cave in Canary Islands

Zachary Shahan — Fri, 28 Aug 2009 11:51:23 +0000

Texas A&M professor and world-leading cave researcher, Tom Iliffe, and others discovered numerous new species in an underwater cave a mile long in the Canary Islands recently. The cave was in Lanzarote off the coast of Africa in the Atlantic Ocean. One of the species might be one of the oldest crustaceans in the world. It might be about 200 millions years old, from the time of dinosaurs.

Journey into the “Great Pacific Ocean Garbage Patch” — Scientific Findings

Zachary Shahan — Fri, 28 Aug 2009 09:20:27 +0000

The “Great Pacific Ocean Garbage Patch” lies about 1,000 miles from the coast of California. It is in the North Pacific Ocean Gyre, which is one of the oldest and most diverse ecosystems in the world. The garbage patch has gotten a lot of media attention in the last year. However, due to the fact that one must get on a boat and go all the way out to the patch to study it, there hadn’t been any in-depth scientific analysis of the patch,… until now.

The Scripps Environmental Accumulation of Plastic Expedition (SEAPLEX) went on an in-depth search of the “Great Pacific Ocean Garbage Patch” this month. Their findings were varied.

Growing Acid in our Oceans: A Looming Threat to Sea Life

Daniel Hohler — Thu, 13 Aug 2009 20:07:38 +0000

This picture is a picture of the beautiful Monterey, California coastline. This is where I grew up. It is famous for it’s beautiful sea life. Sea otters, jelly fish, sea lions, kelp forests all populate the Monterey coast. The Pacific Ocean is the largest ocean in the world. Yet, with all that mass of water, we humans are changing the chemical properties. The acid levels in the pacific ocean, as well as every ocean around the world, are rising. If things keep going this beautiful coastline, my home, will become a wasteland of acid. Habitable to only the most extremophiles.

Rewind our story. Fossil fuels are not just a problem for our atmosphere. When we burn fossil fuels carbon dioxide falls down into the sea. The carbon dioxide is quickly converted into carbonic acid. Carbonic acid has been known to be corrosive to corals and shellfish, and now scientists are discovering that rising acid levels in the ocean are effecting other animals as well.

Killer Kelp

Daniel Hohler — Mon, 03 Aug 2009 18:41:07 +0000

When I was doing research on Catalina Island, there was a wanted poster hanging in the dive locker. Although, this wanted poster was not for any bank robber or bandit. This was a wanted poster for kelp. Undaria pinnatifida, an invasive species from Asia that has hitched a ride on boat’s hulls and ballast water. Also known as wakame, you may know that name as an ingredient in many Asian dishes or miso soup.

Wakame has become a large problem from New Zealand to Monterey Bay. It is an aggressive and costly intruder that takes over a habitat at the expensive of the native species. Since its discovery in San Francisco Bay, 140 lbs of the kelp have been removed from the San Francisco Marina alone. Wakame’s destructive nature has earned it a spot on the 100 of the Worlds Worst Invasive Species list.

Is there Really Plenty of Fish in the Sea?

Daniel Hohler — Thu, 23 Jul 2009 18:52:17 +0000

In 2003 “Nature” published a study showing that 90% of the large fish living in our oceans were fished out of existence. A group of scientists recently predicted, major seafood stocks will collapse by 2048. This is a staggering number, considering the technology and amount of people needed to cause overfishing is a relatively new phenomenon, starting really only in the late 19th century.

Most governments have shrugged these claims off, and continued their fishing practices. Alaska has shown to be the only sovereign state willing to self-police their fishing practices. Sarah Palin jokes aside… Threatened with the loss of one of its top industries, Alaska began limiting the number of fishing vessels, restricting the size of their catches; and perhaps most importantly, giving incentives to fishermen. Alaska currently gives fishermen a stake in the long-term viability of salmon and other fish.

Will Chile Give Land-Locked Bolivia Ocean Access Via Tunnel? I Hope Not

Levi Novey — Fri, 22 May 2009 08:48:25 +0000

Technological innovations can solve some of the world’s biggest problems right? That’s what a firm of Chilean architects would like us to believe. They’ve come up with a creative idea for how land-locked Bolivia could regain access to the ocean. It was not too long ago, in 1883 to be exact, that Bolivia lost the little coastline it had in a war with Chile. Since it’s only be gone for a short time, now’s the perfect time to get it back!
