NZ has just seen the biggest whale stranding ever, located at Farewell Spit … 400 whales beached with 70% of those quickly lost. Tragic and heartbreaking news. Here is a mainstream media link to the event:
We are generally told that these events are natural. In the above article at the link there is another article … Why whales strand and how to help them. It cites the usual reason proffered; ‘whale strandings are natural occurrences’.
Media is predictably quick to eliminate man’s interference with the environment as being causal regarding any environmental damage. And if you’re familiar with this site you will know that this denial is not uncommon. Corporations whose focus is on greed and profits all vehemently deny that their practices cause damage. They are also well armed with a bevy of well paid lawyers to ‘legally’ destroy anybody who threatens those profits. People are targeted, assaulted and even lose their lives standing up to corporate profiteering.
That said, it is well to search for and consider the independent information on all events since corporations cannot be trusted to tell you the truth. They tell bold faced lies. If you doubt that watch ‘The Corporation’ doco found on the Corporations page.
The Threat of Underwater Noise Pollution to Marine Life, Particularly Seismic Testing
The following short video from oceancare.org explains concisely the threat of noise to marine life saying “underwater noise pollution is a serious threat…” (the phenomenon media doesn’t mention).
At 1.45 minutes the effect of sonar from military ships is explained and at 2.22 minutes, the effects of seismic exploration for oil and gas on marine life. As many Kiwis will know our oceans are now replete with activity from the latter, especially since our ‘esteemed’ and recently departed leader John Key signed away drilling rights to his corporate friends. Key and his corporation (aka known as the NZ Government) have no regard whatsoever for our natural environment. Corporations are about profits not people or environments. See more on Key below.

VIDEO INFORMATION: “Basically, John Key is killing whales and dolphins, and potentially ruining the seafood (crabs, crayfish etc) industry in the areas where this seismic survey technology is used.
the Media has not told you ANY of this…
The main environmental concern for marine surveys is the potential of seismic sources to disturb animal life, especially cetaceans such as whales, porpoises, and dolphins. Surveys involve towing an array of 15-45 pneumatic air guns below the ocean surface behind the survey vessel and emit sound pulses of a “predominantly low frequency (10–300 Hz), high intensity (215-250 dB).
Seismic surveying can damage the reproductive processes, auditory functions and other damaging effects to highly lucrative marine species (lobster, crab) and it poses potentially fatal effects to marine mammals.
Seismic testing is not fully responsible for whales running ashore or becoming stranded, but there is evidence that it plays a major role. Studies of seismic effects on several whale species such as Gray, Bowhead, Blue, Humpback and Sperm whales indicated substantial effects in behavior, breathing, feeding and diving patterns.
Beachings and Seismic Tests
On November 28, 2004, Reuters reported that during a three day span, 169 whales and dolphins beached themselves in Tasmania, an island off the southern coast of mainland Australia. The cause for these beachings is not known, but Bob Brown, a senator in the Australian parliament, said “sound bombing” or seismic tests of ocean floors to test for oil and gas had been recently carried out near the sites of the Tasmanian beachings.
According to Jim Cummings of the Acoustic Ecology Institute, seismic surveys utilising airguns have been taking place in mineral-rich areas of the world’s oceans since 1968. Among the areas that have experienced the most intense survey activity are the North Sea, the Beaufort Sea (off Alaska’s North Slope), and the Gulf of Mexico; areas around Australia and South America are also current hotspots of activity.
The impulses created by the release of air from arrays of up to 24 airguns create low frequency sound waves powerful enough to penetrate up to 40km below the seafloor. The “source level” of these sound waves is generally over 200dB (and often 230dB or more), roughly comparable to a sound of at least 140-170dB in air.
According to the Australian Conservation Foundation, these 200dB — 230dB shots from the airguns are fired every 10 seconds or so, from 10 metres below the surface, 24 hours a day, for 2 week periods of time, weather permitting.
These types of tests are known to affect whales and dolphins, whose acute hearing and use of sonar is very sensitive.
On December 24, 2004 there was a magnitude 8.1 earthquake more than 800 kilometres southeast of Tasmania near New Zealand, with a subsequent aftershock 6.1 a little later in the morning that same day.
Then on December 26 the magnitude 9.0 earthquake struck leading to the devastating tsunami that killed more than 300,000 people.
On December 27, 20 whales beached themselves 180 kilometres west of Hobart on the southern island state of Tasmania.
As part of Budget 2009 a total of $20 million over three years will be allocated to the seismic data acquisition programme run by Crown Minerals, which is responsible for the administration and promotion of New Zealand’s oil and gas.
