Why Sound Is So Important In The Marine Environment

Without the ability to optimize the use of sound, many marine creatures would be unable to exist. In the ocean environment; sound takes over where sunlight leaves off.

Dophins Often Protect Us

By now, most of us have read stories or heard tales of dolphins coming to the rescue of swimmers and divers, and I thought this would be a good time to share some insights. We are now being asked to reconsider the impact that we have on the local orca population, and on October 27th our window for discussing the proposed guidelines for vessels and orcas will close. Hopefully we will come to understand the reasons and value of that increased protection - one of which is the mysterious nature of the whales themselves.

The bottom line is that for many species of dolphins, porpoises, and whales, their survival depends upon their maintaining group unity and culture, and for some dolphins this leads to demonstrations of compassion towards other species. Last year a dolphin led two beached Pygmy sperm whales to safety, an event which was somewhat astonishing and to my knowledge has not been recorded before.

But I got to thinking about it; this rescue occurred by a dolphin who enjoys being in the company of humans, and would therefore feel safe in coming to the aid of the whales when people were around. So possibly dolphins help species other than their own with some regularity but because they might fear us, or because it happens where we are not around, we just have not been fortunate enough to witness such occurrences.

Or maybe we just don't notice.

I saw the following video clip right before going to Hawaii a while back, and it gave me pause. Already phobic about sharks, seeing this did freak me out a bit, but ultimately having watched it help me to put my fear in perspective and I was able to swim with dolphins and turtles and celebrate the experience (however I did stay alert!). So a gentle warning, it might spook you if you have a vivid imagination. Not recommended for kids either. The titles are in French - essentially they describe the events as seen, which involved a Tiger shark.

For the most part, the people were unaware of the event as it unfolded, and it does make you wonder how often dolphins protect us and we never know.

Currently there is a movie out called "The Cove", which documents the slaughter of dolphins by a nation concerned with competition for fish with the animals, (coupled with a desire to eat the dolphins, it would seem). Yet I wonder how many times people in that nation may have received assistance from dolphins. Certainly, there are no records of unprovoked attacks on humans by dolphins.

I am proud to live in a part of the world where such barbarism is not allowed, and where we have evolved an attitude of seeking to achieve balance in how we relate to the Earth and the other beings that share the planet. We are learning to take a step back from conflict and seek solutions, and I am confident that we can come up with positive outcomes for everyone while protecting our local orcas and the waterways where they live.

The proposed federal guidelines for vessels and orcas can be found here, and we have provided links as well.

Standards of Care for Endangered Whales

Most of our readers here know that L-pod member "Lolita" is from a locally endangered population of orcas, one of only 86 of those whales left. Her life is far from ideal, and she is not being kept in a pool that is legal, even by the low standards set by the theme parks. And what we want to know is how this can be rectified.

In the wild, orcas rarely stop moving. (Photo courtesy OrcaNetwork, taken by Peter Pijpelink)

Marine mammals are protected everywhere in the wild, but when "Lolita's" pod, along with the other pods that comprise the Southern Resident Killer Whales received the status of Endangered in 2007, an exception was written into the documents excluding all members of J, K, and L pods living in captivity at the time. "Lolita" was, and remains, the only living member taken from the wild…so the exception must have been written in to exclude one lonely isolated orca.

Now how did that come to pass? Would it not have made more sense to offer her protection and then let the theme park petition to keep her? Would they then not have had to provide a legal pool for her?

And shouldn't biologists decide what are adequate facilities for marine mammals, not the theme parks themselves?

As a society our values seem to have taken a shift since the early days of zoos, circuses, and theme parks - we really don't enjoy tired acts and worn out displays, and it is painful to think about intelligent, harmless and gentle beings confined in miserable looking situations away from others of their own species.

Yet we are conflicted…we have learned a great deal about orcas and other dolphins by studying captives, and we want to increase our knowledge. Reasonably enough, both polls (here and Facebook) show that if dolphins and whales are in captivity, most poll takers expressed that it should be for research purposes – although I think that there is far more to be gained by researching them in the wild at this point.

In the meantime, a member of a locally endangered species languishes in a sad theme park without the company of her own species, in a substandard pool.

I have written to both Senator Patty Murray and Senator Maria Cantwell and requested that they share with us explanations as to the government's lack of action, and will post their replies when I receive them.
