Stopping Plastic Bags Before They Reach the Oceans

Posted on by July 3, 2018

The best way to combat plastic pollution in the oceans is to stop the plastic before it gets there.

We have been posting about the ever-growing garbage patches in the world’s oceans for the better part of a decade. The posts are beginning to have a certain sameness. Things are getting worse. The garbage patches trapped in the ocean gyres are getting growing larger. Six years ago, the Eastern Pacific Garbage Patch was a wide as the Continental United States. Whales are dying from ingesting plastic.  Record levels of microplastics are being found in Arctic ice.  A popular dive spot near Bali is turned into a “sea of trash” by plastic bags. And on and on and on.

Kayaking Through the Engine Room of MV E Evangelia

Posted on by July 2, 2018

The MV Empire Strength, a 7,355 GRT refrigerated cargo ship, was built by Harland and Wolff in 1942.  In her long career, she had seven owners and four names. When she was purchased by a Greek owner in 1965, she was renamed, MV E Evangelia.  Her sailing days ended when she ran aground in 1968 in the Black Sea on the coast of Romania near the seaside resort of Costinești. With her back broken, she was declared a constructive total loss and abandoned. Now the wreck is a local attraction.

The video below captures a kayaker who paddles through an opening into the shell into the engine room. The first diesel engine is probably a generator while the six-cylinder main engine towers above the paddler in the background. The video has a slightly otherworldly quality, like images from a video game or a steampunk dream.  Continue reading →

Diving the USS Oriskany — the Great Carrier Reef on Florida Panhandle Shipwreck Trail

Posted on by July 2, 2018

USS Oriskany is an Essex-class aircraft carrier completed after World War II. She served in both the Korean and the Vietnam wars. In 2006, the almost 900′ long  ship became the world’s largest artificial reef after being sunk 22 miles south of Pensacola in more than 200 feet of water, as part of the Florida Panhandle Shipwreck Trail. Nicknamed the “Great Carrier Reef.” The top of the ship is within 80 feet of the surface and there are considerable portions of the ship in less than 100 feet of water, making them accessible to both sport and advanced divers. Here a video of diving on the Might O, the Great Carrier Reef. Continue reading →

Testing the SeaBubble Fly-By-Wire Control System

Posted on by June 29, 2018

A year and a half ago we posted about SeaBubbles — foiling electric water taxis. The idea to develop a five-person water taxi comes from Alain Thébault, the designer and skipper of record-breaking ocean-going hydrofoil Hydroptère. The distance from an idea to implementation, however, can be considerable. The SeaBubbles feature fully submerged foils which require a sophisticated control system for the craft to remain stable. The SeaBubble team are attempting to achieve a ride as smooth as a car on a well-paved road by using an advanced fly-by-wire control system. Fly-by-wire is a term used in aeronautics to describe a semiautomatic computer-regulated system for controlling the flight of an aircraft. While the SeaBubbles will not take off, they will be flying on foils. Here is a short video about the SeaBubble fly-by-wire system. Continue reading →

SV Kwai — Cargo and Passenger Service Under Sail in the South Pacific

Posted on by June 28, 2018

We recently posted about crewing opportunities for the auxiliary-sail trading vessel Tiare Taporo operating from the Cook Islands. The Tiare Taporo is, however, not the only commercial sailing vessel serving the Cook islands. The SV Kwai will soon be departing on its 45th voyage from Hawaii calling on the islands of Kiritimati (Christmas Island), Tabuaeran (Fanning) and Teraina, (Washington Island) as well as the Northern Cook Islands of Penrhyn, Rakahanga, Manihiki, Nassau, and Pukapuka.

The SV Kwai is 43 meters (140 ft), with a beam of 7 meters (23 ft), draws 3 meters (10 ft), has a tonnage of 179 RT and is ketch rigged. While equipped with a main engine and generator, the goal is to operate under sail 90% of the time. SV Kwai has been carrying cargo and passengers between Hawaii and the Line and Cook Islands since 2006.

Grouper Eats Lionfish — Does the Invasive Fish Face Local Predators?

Posted on by June 28, 2018

Sometime in the 1990s, two different species of lionfish made it into the waters of the Atlantic off Florida. Native to the Indo-Pacific, the venomous, predatory fish spread rapidly, decimating local reef fish in the Atlantic, the Gulf of Mexico, and the Caribbean. Lacking local predators to stop its spreading, the lionfish have been described as “one of the most aggressively invasive species on the planet“. So far, the most effective means of slowing the spread of the fish is for divers to spear them, a relatively slow and challenging approach.

I recently came across a video from 2015, showing a grouper eating a lionfish. Groupers and sharks are natural predators for the lionfish in the Pacific, but the Atlantic and Caribbean groupers have been slow to adapt to considering the new invader as a food source. Are local groupers and other predators developing a taste for lionfish? About the video: Continue reading →

Trade War Hits Maine & Alaskan Fishermen

We recently posted about concerns that the current Maine lobster boom may collapse in time due to climate change. The fishing industries in Maine and Alaska are facing a far more immediate challenge, however. New US tariffs on steel and aluminum and retaliatory tariffs on lobster imports by China could drive up costs and cut lobster exports while giving Canadian lobstermen an advantage. Likewise, retaliatory tariffs on salmon and other Alaskan seafood could seriously hurt their fishing industry. 

As of July 6th, China will impose an additional 25% tariff on Maine lobster. China buys about a fifth of American lobster exports, valued at $137 million. The tariff is expected to give Canadian lobster exporters, who are not subject to the tariff, an advantage in the Chinese market.

Antarctica Melting Three Times as Fast as a Decade Ago

Posted on by June 25, 2018

A new study from the journal Nature makes a terrifying observation — the rate at which Antarctic ice is melting has tripled from only a decade ago. This is significant as more than 60 percent of the freshwater on Earth is locked in Antarctica’s ice sheets. The continent has lost nearly three trillion tons of ice since 1992.

The New York Times reports that the continent is now melting so fast, scientists say, that it will contribute six inches (15 centimeters) to sea-level rise by 2100. That is at the upper end of what the Intergovernmental Panel on Climate Change has estimated Antarctica alone could contribute to sea level rise this century.

Looters of Wreck of HMS Hermes Found Guilty

Posted on by June 24, 2018

HMS Hermes

Last year we posted about warships from World War II that had vanished after illegal scrappers literally cut them up and hauled the steel away. Here is a news item on theft on a different scale and with a better outcome. Recently two divers, Nigel Ingram, 57, and John Blight, 58, were found guilty of looting items from the World War I wreck of the HMS Hermes in the English Channel. The two divers stole more than 100 items,  including a torpedo hatch, launch panels, and chinaware. The total value of items stolen from the wreck was reported to be more than £150,000.

Maud Returns Home — Home Trip 2018

Maud Returns Home – Facebook

For several years, we have been following the attempts to raise Arctic explorer Roald Amundsen‘s research ship Maud from where it has been sitting in ice and mud for close to 90 years. To say that the conditions in Cambridge Bay off the Nunavut territory of northern Canada have been challenging would be an understatement. Over the last eight summers, a team of Norwegians has been working to raise and ultimately return Maud back to Norway. In the summer of 2017, they achieved a major milestone — successfully towing the Maud on the barge Jensen out of  Cambridge Bay to Aasiaat on West Greenland. They are now preparing for the final leg of the journey.

A Look Inside the Abandoned Soviet Sub in Amsterdam

Posted on by June 21, 2018

A group of “urban explorers” ventured out to climb aboard an abandoned Soviet submarine tied up in the Maritime Quarter, the former NDSM shipyard in Amsterdam North, in the Netherlands. The submarine was built in 1956 or 1957. It was designated 4711 B-80, and is variously described online as either a Zulu or a Foxtrot Class submarine. (The B-80 appears to be one of the last of the earlier Zulu class.)

Is the Collapse of the Maine Lobster Industry on the Horizon?

Posted on by June 21, 2018

Today, the New York Times featured an article titled — “Climate Change Brought a Lobster Boom. Now It Could Cause a Bust.” The article suggests that while rising water temperatures due to climate change have brought a boom in the Maine lobster catch, increasing temperatures may lead to a collapse of the fishery.  This concern is nothing new. Five years ago, we posted “The Ecology and Economics of Lobster – Will The Maine Lobster Boom End in a Bust?”   Increasingly, the signs of a bust are becoming more ominous.

The NYTimes quotes Dave Cousens, who stepped down as president of the Maine Lobstermen’s Association in March, “Climate change really helped us for the last 20 years.” But, he added, “Climate change is going to kill us, in probably the next 30.”

Over 190 Feared Dead After Sumatran Ferry Sinks in Lake Toba

Posted on by June 20, 2018

Lake Toba

A ferry across Lake Toba in North Sumatra sank on Monday in bad weather and a reported 192 are missing and feared dead. Only 18 survivors have been rescued. Rescuers looking for additional survivors have been hampered by high winds and rain. The ferry’s legal capacity is reported to have been between 43 and 60 passengers, depending on the sources, with a comparable number of personal floatation devices (PFDs) aboard. 

Lake Toba is a popular tourist destination and at 450m (1,500ft) deep one of the deepest lakes in the world. The lake was created by an ancient volcano eruption. Ferries run between a scenic island in the middle and towns on the shore.

Sadly, Indonesia, a country of some 18,000 islands, has one of the world’s worst ferry safety records.  Continue reading →
