Thriving Oceans

The heavy rains currently beating down on the East San Francisco Bay Area has reminded me about the incredible amount of debris that will be entering our waterways and oceans.  We are all aware of the Great Pacific Garbage Patch, but there is an enormous amount of other debris that is left to surf the waves.  Take for instance fishing nets.  Unattended and discarded fishing nets pose danger to the entire ocean system, even whales.  Check out the following pictures from The Marine Mammal Center and the results of their necropsy of a dead sperm whale recovered in March 2008.

“On March 16, The Marine Mammal Center’s Director of Veterinary Science, Dr. Frances Gulland, assisted in the necropsy of a 51-foot-long sperm whale that  had washed up on a beach near Tomales Point in Point Reyes, CA. When the necropsy team reached the animal’s internal organs, they discovered nearly 450 pounds of fishing net, mesh, braided rope, plastic bags, and even a plastic comb in the whale’s stomach.“

Coming off the heels of Hope for small sea turtle populations, there is yet another stint of positive ocean conservation news; this time for our cetacean friends.  A new publication in Conservation Biology has actually documented voluntary cooperation by shipping vessels to avoid whale strikes. 

Fin, humpback, right and gray whales have the unfortunate distinction of being the most frequently reported victims of collisions based on historical records.  But whale strikes are not limited to only those species as deaths have been noted for sei, blue and minke whales as well.  However, one particular cetacean stands out above the whale strike crowd with victimhood reaching 2 orders of magnitude above the others.  Perhaps its affinity for urbanized coastal waters around the globe, the endangered North Atlantic right whale is in need of a little shipping compassion. Especially when a 2008 report found that  53% of North Atlantic right whale deaths were attributed to vessel strikes.

To curb the problem, conservation policies have been discussed and even implemented, including the establishment of an ‘area to be avoided.’  In 2007, “The International Maritime Organization adopted the Roseway Basin Area to be avoided on the Scotian Shelf as a voluntary conservation initiative to reduce the risk of lethal vessel strikes to right whales.”  This voluntary area to be avoided went into effect on May 1, 2008 and was designed to be seasonally effective from June 1 to December 31st of each year.  With shipping companies traditionally against the execution  of speed reduction regulations and alteration of shipping lanes (i.e. time is money), the notion of a voluntary avoidance area was definitely a concept that needed confirmation of compliance.

To my surprise, the researchers found:

” Estimates of vessel-operator voluntary compliance ranged from 57% to 87% and stabilized at 71% within the first 5 months of implementation. Our estimates showed an 82% reduction in the risk of lethal vessel strikes to right whales due to vessel-operator compliance. We conclude that the high level of compliance achieved with this voluntary conservation initiative occurred because the area to be avoided was adopted by the International Maritime Organization.”

But the caveat with ocean-going vessels avoiding a conventional shipping lane was that they needed to find a new travel route.  And although the newly adopted course was quite favorable to the right whale, it has the potential to increase fin whale ship strikes by approximately 7%.  The argument, however, is that the fin whale population is 250 times more than that of the endangered North Atlantic right whale, right whales are more abundant than fin whales in the ‘area to be avoided’ , and the ship-strike risk to humpback whales and to sei whales will be reduced by 11% and 74% respectively.

So what does a reduction in ship strikes ultimately mean to the endangered North Atlantic right whale, well it may very well be the difference between recovery and extinction.

“Preventing as few as two female deaths per year would increase the population growth rate to replacement levels that would initiate recovery.  Such prevention is particularly relevant given that contemporary probability estimates of deaths from vessel strikes could be as high as 10 individuals in any given year.”

Now that I’ve covered ‘Whale Wars’ and the ‘Institute for Delicious Whale Research’ over the last week, I thought I’d keep on topic and present some information over the very controversial  “Scientific Permit Whaling.”

The 1946 International Convention for the Regulation of Whaling established Article VIII that provides a means by which whales may be killed for scientific purposes.  But what is most interesting and surely limits any authority of the International Whaling Commission (IWC) is that issuing a scientific whaling permit is actually decided upon by individual nations.  Although the nation has to submit a proposal, the Convention says,

“…it is the member nation that ultimately decides whether or not to issue a permit, and this right overrides any other Commission regulations including the moratorium and sanctuaries.”

So what does this all mean for whales?  Well it means that the IWC has no direct effect on preventing the continued slaughter of whales.  IWC established sanctuaries are in reality not off limits to whaling, and harvesting can continue under the guise of research without any Convention/Commission repercussions.  The IWC is limited to Resolutions that ask governments to abstain from issuing scientific whaling permits, but as per their own words:

“While the Commission cannot interfere with the right of a member nation to issue a permit, it can comment on the permit, after receiving the report of the Scientific Committee.”

Unfortunately comments, strong words and resolutions are not enough of an incentive for some nations to refrain from sinking a harpoon into the side of a fleeing whale.  And as if the situation couldn’t become even more laughable, the IWC member nations, for instance, could not even come to a unanimous decision whether to vote in favor of a 2007 resolution against Japan’s Antarctic whaling program or not.  For all practical purposes the resolution did pass with 40 votes in favor, 2 votes against and 1 abstention, but there were 27 countries that “decided not to participate in the vote as they believed that the submission of the proposal was not conducive to building bridges within the Commission.”

But  there is an environmental  irony with  Japan’s Antarctic whaling program, known as JARPA II, as well.  According to what was presented to the IWC by Japan, the objectives of this so-called scientific harpooning are:

1. monitoring of the Antarctic ecosystem;
2. modeling competition among whale species and developing future management objectives;
3. elucidation of temporal and spatial changes in stock structure;
4. improving the management procedure for Antarctic minke whale stocks.

Since the feasibility study has been completed, the JARPA II program will commence under full-scale research with scientific permits issued for 850 (plus 10%) Antarctic minke whales, 50 humpback whales and 50 fin whales per year.

Hmmm…now I am starting to see the light. Saving, improving and monitoring the Antarctic ecosystem by removing species vital to its health must be sound science.

As  ‘Whale Wars’ season 2 finale rolled its credits a couple weeks back I have been left contemplating whether or not I would actually broach the topic on Thriving Oceans.  To be honest I have been throwing the idea back and forth ever since season 1, but I always managed to find something else to capture my attention (perhaps on purpose).  Now that the season is over and I’m sure has already circulated throughout the blogs, I am left with what may just be a passé post.  But, since I already started I decided to continue on and see what happens to pop onto the page.

In nothing less than a rollercoaster ride of emotions, the last two episodes brought whaling out of the shadows and plastered it over television screens throughout the world.  Sure I’ve seen the sickening whaling footage captured by the likes of Greenpeace, but in a sense of irony, as I am watching a program about whaling, I was not fully prepared to witness the slaughter in a Friday night context.  And if you’re thinking this is a case of ‘out of sight, out of mind’ on my part you are indeed correct.

What I found most interesting was the fact that while I was (and still am) truly appalled by the Japanese whaling activities and left mocking their propaganda-esque banners claiming they are “taking tissue samples,” or “studying stomach contents,”  I found myself wondering if a line had been crossed when the Sea Shepherds collided with the Yushin Maru #3 harpoon ship.  Did I betray my own beliefs by asking such a question?  I just saw a number of whales loaded onto the processing ship and a whale finally succumb to a very graphic death at the hands of the Japanese whaling fleet , so how could I even mull over whether the collision was justified? Especially since there is no doubt with whom I side.

Well, perhaps this says something about my character and perhaps it is also a case of filling the role of an armchair captain that drove my initial reaction.  But after careful introspection I, firstly, cannot say what I would do in the heat of witnessing such ocean atrocities, and secondly I just cannot  bring myself to say it was the wisest of all decisions.   My uneasiness  with the collision was not the byproduct of compassion for the whalers themselves, but for the cause I support.  Had someone been critically injured I am left wondering how that would have detrimentally affected direct/indirect action, whether by Greenpeace, Sea Shepherd Conservation Society, or other non-profits, against whalers in the future.  We need to ensure those groups are available to continue their campaigns and not locked up in an international legal incident.

While policies need to change for the elimination of all whaling, thwarting Japanese efforts to fill their quotas in the meantime should be conducted in ways  that will not harm the ultimate goal. With that said I have no problem with riding the edge to protect whales in the Southern Ocean.   And while the whale warriors prepare for another season of cetacean protection, the vast majority of us are left simply watching from afar.  Instead of being mere observers we should also embark on a journey…a journey of support, of letter writing campaigns, and of boycotts to aid all of the great organizations working to bring an end to the harpooning of whales.

Sometimes it takes a man in black (or people in black in this case) to walk the line and bring a cause back  to the worldwide stage.

Video released by the Scripps Institution of Oceanography

“The resulting video, recorded using ambient light at 100 meters (328 feet) depth, not only successfully gave the fishermen a clear idea of how the thieving whales were stealing the fish-they pluck the line at one end to jar the black cod free at the other end, somewhat like shaking apples from a tree-but it gave scientists a chance to match the animal’s acoustics with video depictions of its physical features.”

“Scientists have documented the first known migration of blue whales from the coast of California to areas off British Columbia and the Gulf of Alaska since the end of commercial whaling in 1965.”
