Deep Sea Mining of Hydrothermal Vents
The Canadian (and BC-based) company, Nautilus Minerals has emerged as a major player in the exploration of deep-sea mining possibilities, most notably through its activities related to mining the waters off the coast of Papua New Guinea. Nautilus is also interested in mining areas offshore from Vancouver.
Last week, Wood's Hole Oceanographic Institution hosted a Deep-Sea Mining Workshop to promote interdisciplinary and international collaboration on deep sea mining issues. While there was only modest media coverage of this 100-person, invite-only event; deep-sea mining is becoming a hotly-contested issue for many people who are concerned about the health of the oceans. Rick Macpherson, a scientist based in San Francisco, offers some interesting reflections on the workshop.
Sea floor mining on a large scale has never been attempted before, so we can't fully understand the environmental implications of such a practice. What we do know is that deep sea systems are vulnerable and are often slow to recover from damage. One of my specific concerns is that there are many different kinds of marine life that exist near the hydrothermal vents and if we are not careful, deep sea mining could alter or harm the ecosystem upon which these creatures depend.
What are your thoughts on deep-sea mining? How would you feel if deep-sea mining occurred on the Pacific coast of Canada?

New Wave Energy Project
The Canadian government recently gave $2.7 million to SyncWave Systems to fund the demonstration of an ocean wave converter on the west coast of Vancouver Island.Oil Spill Blackens One of Australia's Pristine Island Beaches
This is what happened a week ago near Brisbane, Australia when the 185 meter container ship, Pacific Adventurer, enroute from Newcastle to Indonesia via Brisbane ran into heavy seas whipped up by the tail end of Cyclone Hamish, a category 5 storm. The Brisbane Tropical Cyclone Warning Centre defines a Category 5 Cyclone such as Hamish as extremely dangerous with widespread destruction . Heavy seas can be encountered even after the cyclone has diminished in intensity.
The government of Queensland has declared Moreton Island and the southern area of the Sunshine Coast a disaster area. These are beautiful, pristine islands considered as sacred places by the local Aborigine people and the miles of sandy beaches are highly valued by tourists only a short ferry ride away from the greater Brisbane area.

The ship was seven nautical miles east of Cape Moreton when it reported losing 31 of a total 50 shipping containers of ammonium nitrate being carried on its deck. Several of the fallen containers pierced the ship's hull, resulting in an oil spill originally estimated at 30 tonnes."This is a very serious situation," said Queensland Premier Anna Bligh today, after a meeting of the emergency response group - members of key government agencies.
"I'm advised that it appears the volume of oil involved is much greater than originally reported by the Pacific Adventurer," she said. "And the effect of the oil spill is more widespread."

So far more than 50 per cent of the 74 kilometres of coast polluted by the oil spill had been cleaned up. But fears remain over 31 missing containers of fertilizer. (ammonium nitrate)
The Federal Government yesterday called in navy minehunter HMAS Yarra to find the containers of ammonium nitrate, which could cause algal bloom in high concentrations.
Maritime Safety Queensland believes the containers have sunk 150 metres to the ocean floor. Three separate investigations are being conducted by the Australian Transport Safety Bureau, Maritime Safety Queensland and the Australian Maritime Safety Authority. They will look at the ship's seaworthiness, how the containers were stowed and circumstances surrounding the accident.

This marine disaster, while not huge, will still have long term environmental consequences for the region. You can check out a short news video on this oil spill here: http://media.theage.com.au/?rid=47024
Stories like this serve to illustrate what can happen with dramatic increases in large tanker traffic on the B.C. coast. http://www.marinergroup.com/oil-spill-history.htm
Almost every maritime nation has had numerous marine disasters like these, some more destructive than others. The link above lists many of them. Most are caused by ships collisions or groundings. Even with the most sophisticated marine traffic management schemes governing the most modern vessels, spills happen.
It is interesting to note that on March 26 and 27, in Richmond, B.C., the Pacific North Coast Integrated Management (PNCIMA) Forum, a two-day event that will engage people and organizations in the development of an integrated approach to oceans management for the Pacific North Coast Integrated Management Area (PNCIMA) will have as it's first focus the establishment of a stakeholders working group on shipping and marine transportation in the PNCIMA region.
For more information on oil spill concerns and the potential impact of an oil spill on B.C.'s coast, check out Living Oceans Society's oil spill model here:http://www.livingoceans.org/programs/energy/model/As the Local Ecological Knowledge Coordinator for Living Oceans Society I would be interested to know what your thoughts might be on the subject of increased tanker traffic on our coast, especially if all or some of the proposed pipeline mega projects slated for the ports of Kitimat and Prince Rupert come to fruition.

Community-Supported Fisheries
Port Clyde, a small fishing village (at a population of 1000, it's only a little bigger than Sointula) off the coast of Maine, has found an innovative (and sustainable!) way to save its local fishing economy: community supported fisheries. The idea behind community supported fisheries is simple: people in the community pay a local fishing cooperative an up-front fee to receive a weekly ration of the in-season catch (shrimp in the winter and groundfish in the summer). Fishermen get a higher price for their product (because they have eliminated the middle-men buyers and sellers who take their own cut of the profits), and the community gets a weekly supply of fresh-caught seafood.Thursday, February 12, 2009
