Kovin laajoja ja seikkaperäisiä selvityksiä ilmiöstä ei tunnu löytyvän, mutta jotakin sentään.
Ebsco-artikkelitietokannassa on luettavissa seuraava lyhyt artikkeli:
EXTREME SURFING ON THE AMAZON
Surfing on a river? Every year, surfers gather for a championship on the Amazon River. They call it "Amazon not-com."
Ocean tides smash up the Amazon twice a day. The tides cause a wave 15 feet high to roar upstream. This wave is called the pororoca, or "big noise." It is
full of crocodiles, trees, garbage from the river bottom, and fish with nasty spikes.
Why would champion surfers want to ride the pororoca? If you do it just right, you can ride the wave for a long time--as long as 17 minutes. That is a lot
longer... |
