Icebergs off the Starboard quarter

[seafox]

Never felt a thing. We had another one yesterday about lunchtime. I probably thought it was indigestion

11.42AM, 4.6, 50Km down and 50Km away from you. The events were just 10Km apart.
I have always found Fishing to be pathetic after an earthquake and it can stay that way for many days afterwards. It must upset them down there somehow.

I felt one at Punga a few years ago. I was a still evening and we were on our boat. The water went all choppy and confused like wind against tide and you could feel the rumble through the bottom of the boat. At first I thought I was a bit pissed but then realised it was an earthquake.

[Alan Wheeler]

As long as all the water doesn't drain away, because I won't being hanging around to laugh at all the flapping stranded fish, watch me climb them thar hills. It'll be record setting.

Anyone have any pictures of them from shore?

[Alan Wheeler]

There was news video taken of them from shore. But I just searched the Websites of both our news stations and can not find any of the "from shore" video footage. There are plenty of stories of them though if you want to take a look. http://tvnz.co.nz/view/page/425824/894087

Found it, but if you can see the thing, you have a better monitor than mine. http://tvnz.co.nz/view/video_popup_windows_skin/894293

I guess I have a better monitor that you do Nice video

those shotz with the helicopter in are pretty neat. Shows the size of them. Hey Alan, do you have an aircard with broadband? Click it broadbank speed on the video and it is bigger and clearer.

[Alan Wheeler]

Aircard??? no I don't fly much. I don't think I even have any frequant flyer miles.
Broadband?? Nah, the band around my computer is a thin blue one. Does that make a difference? It must be like painting a racing strip onto the car to get that extra couple of mile an hour huh?

[seafox]

It's like "Air gun mate" "Not bad thanks"
"Cheers Bro"

[Alan Wheeler]

Oh those yanks ain't goin to get that one ;-) :-)

Hey did ya see the next set of bergs approaching. One is 1Km long. However, I was looking at a site that tracks the bergs as they leave the Ice shelfs. They only track the real big ones. They start off at around 50Km in length for the smaller ones they track and one at present is over 100Km in length.

It seems the set that has reached NZ came from the Weddel sea area. That means they must have vertually circumnavigated the entire Antarctic circle before they drifted north under Oz and up to us. It has taken five years or more for the journey. Wow!

[seafox]

There must be a lot of berg underneath as they are beached miles out from the land. Pretty amazing alright.

[Alan Wheeler]

I have heard everything from 2/3rds under the water to 90% under the water. If it is 2/3rds, then at 100m high, then the things are 300m deep. If they are 90% under, then they are somewhat further down again. They won't get over the shelf at that depth and will either beach or grind themselves along the edge of the continental shelf.
I notice two peguins on the berg. Mate they are going to have a long swim home again eh!

It's the difference in volume above and below the waterline; not necessarily height.

Ice has a density of .917, sea water depends on the salinity but roughly 1.02-1.03. So about 8% of the mass is above the water.
