University of Kiel researchers Klaus Vaneslow and Claus Ricklefs, who looked at sightings of beached sperm whales in the North Sea between 1712 and
2003 have reported that the beachings may be due to surges of solar activity. The study found that the solar surges possibly disrupt the whales
internal compasses and speculates that the whales may have a magnetic orientation similiar to pigeons, who navigate by small magnetic crystals on
The sun experiences cycles of activity which range from eight to 17 years, with 11 years being the average.
Short cycles are linked with periods of high energy output, while long cycles are believed to be low energy.
Changes in levels of solar radiation have a big effect on earth's magnetic field.
The most notable events are solar flares that cause shimmering lights, called aurorae, in the magnetic fields in polar regions.
Big solar flares can also disrupt telecommunications and power lines and knock out delicate electronic circuitry on satellites.
The researchers found that of the 97 stranding events reported around the coastal countries of the North Sea over the 291 years, 90 per cent occurred
when the sun cycles were below average in duration.

Whale beaching records were compared to historical data on sunspot activity and it was found that the whale beachings occur when the sunspot activity
is high. It is suggested that the migratory path of the whales could be disrupted by minor changes in the geomagnetic fields entering the North Sea
from the Norwegian Sea.
In the past powerful marine sonar has been blamed for interfering with the whales sense of direction causing them to strand themselves.
