Hello everyone and thankyou all for your kind comments on my 300th posting! Todays' is a seascape from Franz Josef Land. It was take from a zodiac on a cruise round the icebergs. The berg on the left has tipped on its side at some stage - the scalloping is evidence of this.

It was taken with a Canon 10D

The picture was taken at about 10pm (24 hr daylight at this latitude). The hills in the background are interesting. First the low cloud/fog is caused by water vapour condensing due to chilling from the icecap. Secondly, they show clear evidence of isostatic or eustatic 'movement'. Basically, the top was 'planed' off by the ice sheet and the weight of the ice pressed the land down wards. When most of the ice had melted and relieved of the weight, the land rose again (and is still rising). Believe it or not this is still happening in the UK - the north and Scotland are still rising and the south is dipping (it was like a see-saw effect). This is all quite unrelated to present Global Warming effects.

Isostasy is a term used in Geology to refer to the state of gravitational equilibrium between the earth's lithosphere and asthenosphere such that the tectonic plates "float" at an elevation which depends on their thickness and density. It is invoked to explain how different topographic heights can exist at the Earth's surface. When a certain area of lithosphere reaches the state of isostasy, it is said to be in isostatic equilibrium. It is important to note that isostasy is not a process that upsets equilibrium, but rather one which restores it. It is generally accepted that the earth is a dynamic system that responds to loads in many different ways, however isostasy provides an important 'view' of the processes that are actually happening. Nevertheless, certain areas (such as the Himalayas) are not in isostatic equilibrium, which has forced researchers to identify other reasons to explain their topographic heights (in the case of the Himalayas, by proposing that their elevation is being "propped-up" by the force of the impacting Indian plate).

In the simplest example, isostasy is the principle of Buoyancy observed by Archimedes in his bath, where he saw that when an object was immersed, an amount of water equal in volume to that of the object was displaced. On a geological scale, isostasy can be observed where the Earth's strong lithosphere exerts stress on the weaker asthenosphere which, over geological time flows laterally such that the load of the lithosphere is accommodated by height adjustments.

Eustasy and relative sea level change

Eustasy is another cause of relative sea level change quite different from isostatic causes. The term "eustasy" or "eustatic" refers to changes in the amount of water in the oceans, usually due to global climatic changes. When the Earth's climate cools, a greater proportion of the earths water is stored on land masses in the form of Glaciers ,snow, etc. This results in a relative fall in global sea levels (relative to a stable land mass). The refilling of ocean basins by glacier meltwater at the end of ice ages is an example of eustatic sea level rise.

A second significant cause of eustatic sea level rise is thermal expansion of sea water, when the Earth's mean temperature increases. Current estimates of global eustatic rise from tide gauge records and satellite altimetry is about +3 mm/a (see 2007 IPCC report). Global sea level is also affected by vertical crustal movements, changes in the rotational rate of the Earth, (see Postglacial rebound), large scale changes in continental margin and changes in the spreading rate of the ocean floor.

When the term "relative" is used in context with "sea level change", the implication is that both eustasy and isostasy are at work.

Hi James,
here we have a classic Parker Zodiac shot! Good use of this impressive iceberg to hold the foreground and lead us into the low cloud clad hills in the background. Superb notes too, i learned something interesting here, many thanks.

Hi James,

Another wonderful shot of a scene most of us will never seen. And excellent notes teaching many of us things we don't know. A beautiful and very frigid looking seascape. The details of the scalloping iceberg is shown in great detail. Wonderful dof and composition.

Hello James,

Here is it summer but when I look to your picture, I get a cold.
Very good detailed and with beautiful colors picture.

gert

Hi James, excellent image, good info as well. Your explanation is well presented and compliments the image.

Hi,

I a hurry a just marking excellent pictures today. Be back later.

Thanks

Hello James,
Beautifully composed image with great colors and atmosphere. Thanks too for the fantastic note.

You have the eye and the world is your pallet....I get excited every time to see where this next post will be from.....and a cool day shot for a hit summer day here...it has an other worldly look but that is probably because of the complete reversal of weather patterns from when this was taken...like some time warp...but very only as well...has a feeling..

hello James

excellent shot of these icebergs with fine POV & DOF,
and excellent sharpness and details of the frozen snows, TFS

Asbed

White ... peace...ice..snow! All at least superficially very tranquil...A very tranquil shot...
Love it!
Global warming?Hmmm.....
Cheers!

Hi James,

Just a superb land/seascape with excellent detail and d.o.f, must be an amazing site to see let alone capture an image like this, t.f.s

Cheers Rick :)

Hello Jose, Lovely and perfect shot. Beautiful view and great clarity. Wonderful landscape shot. Ganesh

James, thanks for taking us to a place in Russia we would normally avoid for lack of tourist facilities :-)!
Fantastic image of this pristine, beautiful and desolate place on planet earth.
The image is a superlative capture of the ambience of the place.
Your note is highly informative.
TFS and regards.

It looks like it's been chipped like wood!
Very fine contrasty image.
I love the cool tones.
Superb clarity.
Excellent composition.

superbe image nature a conserver précieusement, témoignage du temps des glaces. Jolies scultures de la paroie.

Hello again James, this picture I knew was yours, but I guess that was an easy guess... who else would go that far and bring such a great picture? The pink light is fantastic and it's even more fantastic on such a subject, those big icebergs. The texture comes out beautifully in this light, it's quite fantastic to look at. How impressive such a vision must be... thank you!

Hi James,
Beside that this is taken at a very impressive location, the DOF in this photo is what I really like. Just the right amount of depth to still see details in the BG while the full focus is on the ice formation in front.
TFS,
Niek

Hi James!

This is a great seascape picture with a wonderful perspective given by the subtle composition. The wall of ice on the left points to the horizon and leads us into the image. I also like the tranquility that emanates from the picture.

Kind regards

Markus
