Yesterday was big, but apart from the odd big set producing rebound quite serene. Nothing like west coast Tassie......Mark Sundinhttps://www.blogger.com/profile/05603692749315592080noreply@blogger.comtag:blogger.com,1999:blog-7966256462371281922.post-75616058538127145312010-09-18T15:04:46.197+10:002010-09-18T15:04:46.197+10:00That's interesting about the wave period affec...That's interesting about the wave period affecting the shape of the wave Mark. A quote from another Oceanography website "At a depth of half its wave length, the rounded waves start to rise and their crests become shorter while their troughs lengthen." So the waves off Tassie's West Coast had a 17 second period and peaked at 18.4 metres in 100 metres of water with a wavelength of about 470 metres. And they apparently would be travelling at close to 100 kph!! I bet there weren't any fishing boats out there.......Geoffhttps://www.blogger.com/profile/12507054206147031188noreply@blogger.com
