Title: Antarctic images
Post by: sg_smith on March 05, 2013, 11:32:36 PM
Hello

I love the images that are available on the arctic threads, If is alright I would like to start a thread on Antarctic images.  If this is not the correct way to start a new thread please let me know because I am new to this :)

Hello Vaughn,

Thank you for the article and it has very nice graphics.  The key facts highlighted from the article were very interesting. 

1) volume of ice in Antarctica is 4.6% greater than previously thought.

2) The mean bed depth of Antarctica, at 95 metres, is 60 m lower than estimated.

3) The volume of ice that is grounded with a bed below sea level is 23% greater than originally thought meaning there is a larger volume of ice that is susceptible to rapid melting. The ice that rests just below sea level is vulnerable to warming from ocean currents.

4) The total potential contribution to global sea level rise from Antarctica is 58 metres, similar to previous estimates but a much more accurate measurement.

5) The new deepest point, under Byrd Glacier, is around 400 metres deeper than the previously identified deepest point

Cheers
Susan

I thought that the Antarctic photos at the following site were worth linking to:

http://500px.com/devenphoto (http://500px.com/devenphoto)

Two of the images show nacreous clouds. Nacreous clouds are also called "polar stratospheric clouds" and get their brilliant, rainbow colors from sunlight that's reflected from below the horizon. The clouds are so high — up to 82,000 feet above the Earth — that they continue to glow in these incredible hues long after the sun has gone down.
Unfortunately these clouds also contain nitric acid, which reacts with chlorine that's released by industrial processes — and that little combination of chemicals tends to contribute to the Antarctic ozone hole.

which shows ice drifting away from the coast with a plume like feature (cropped image attached) I would like to know what is going on there. Does anybody here have suggestions?
Title: Re: Antarctic images
Post by: AbruptSLR on September 27, 2013, 06:50:01 PM
Andreas,

As we are past the peak for Antarctic Sea Ice Extent, I believe what you are seeing is a local break-up of some portion of the Antarctic Sea Ice sheet (which happens every year in a manner that depends on winds, tides, temperatures, storms, atmospheric lows/highs, tides, ocean currents, upwelling, etc).

Best,
ASLR
Title: Re: Antarctic images
Post by: Andreas T on September 29, 2013, 01:37:23 PM
You are right not to read too much into a snapshot picture and of course I have no comparison for an interpretation of this year relative to other years. But I am learning from pictures like this which shows similar effects on a larger scale http://rapidfire.sci.gsfc.nasa.gov/cgi-bin/imagery/single.cgi?image=crefl1_143.A2013272013500-2013272014000.250m.jpg (http://rapidfire.sci.gsfc.nasa.gov/cgi-bin/imagery/single.cgi?image=crefl1_143.A2013272013500-2013272014000.250m.jpg) what the holes on the sea ice which can be seen in the ice concentration charts are. It shows me how much ice is driven away from the coast by winds (I am guessing this from the movement indicated on the sea surface) and therefore is as you say highly dependent on weather conditions. Just look at the sea ice extent graph bouncing up and down. August has been a lot warmer than average in Antarctica (see graphs page). Above average sea ice extent in antarctica which is a favoured talking point of some people is not the indication of cooling they want it to be.
As I said not a scientific proof by a long shot but something to keep an eye on and learn about, and it is great to see that part of the world from my living room.

As Neven quite rightly suggests on the 'building projects' thread we best focus on 'cultivating our gardens & minds', that we dont need to travel everywhere.
I confess I was lucky enough to travel to NZ's Scott Base & environs in spring 7 years ago, on an Antarctica Artist Fellowship, so not as a tourist. I was there to 'work', & pay-back time came later!
The idea being that an artist could express some aspect about the continent to the general public, so everyone else didn't need to travel there for themselves to still experience it in some way. That they could journey there through the imagination of an artist.

And now here's another way too, more like being in a movie, with these are 360' panoramic pictures. Yes there are some of these already but the idea with this site is it will gradually grow to cover all sorts of locations around the continent.

Can you give a link to the image where your frame is from, Pmt ?
Here  are air temperatures from PIG
http://efdl_5.cims.nyu.edu/timeseries/NYU_AWS_PIG_timeseries.html (http://efdl_5.cims.nyu.edu/timeseries/NYU_AWS_PIG_timeseries.html)
My guess would be streaks of fog forming where cold air blows over open water at a "steamy"
-1.8degC. The combination of wind from the cold inland and upward convection might roll the forming fog into these streaks. I've seen this effect in MODIS images too and if somebody has more and better info, would like to learn more about this.
The images I have seen have in common: ice drifting away from land opening wide gaps, the white streaks are at roughly right angle to the landward edge, and thinner and fainter near the landward edge.
http://antarcticsun.usap.gov/science/contenthandler.cfm?id=2010 (http://antarcticsun.usap.gov/science/contenthandler.cfm?id=2010) suggests that waves and spray could be part of the story. Ice formation is certainly happening too with dry cold air blowing over the water, but how quickly that happens and shows up I have no idea.

This may not exactly match the categroy, but the video illustrates the interplay of ice conditions, weather and season and the rich biodviersity of the Antarctic seas.

I am now convinced this shows cold wind making ice. There are some thin clouds, distiguishable by their shadows, and extending over water and ice. But the streaks of loose (pancake?) ice on the sea surface  pile up against the edge of the thin sheet of sea ice recognizable by cracks in that ice sheet.
This image reminds me very much of flow visualizations I saw years ago on metal surfaces covered in silocon oil with added white pigment. Air blowing onto the metal plate left streaks of a very similar appearance.

I sooner did not notice the increase of the second large rift. If it does not break it will be one of the largest icebergs

I would like to say I have been visiting this forum since 2012.  I know this because I started

continuing :)

Lastly I saw ASLR was saying he was leaving the forum.  I would be sorry to see this because he has been a great contributer and always supported and encouraged all contributers even myself. So thank you to ASLR.  I hope to see you here again

Peter I. Øy's highest peak (Lars Christensentoppen) is 1640 m asl. It is of course high enough to interfere with the WSW wind on Oct. 8, 2019.

See attached picture, coming from EOSDIS Worldview. The whole picture contains an area of around 400 km x 210 km.

Nacreous, also known as “mother of pearl,” and other kinds of “polar stratospheric” clouds are somewhat rare. Witnessing displays this extraordinary can be a once-in-a-lifetime experience. Readers shared their incredible photos with https://www.spaceweather.com/  editor Tony Phillips, who noted that the display is ongoing.

Hey @all,

this time hopefully in the right thread.

Pictures were taken in the Caldera/Crater of "Deception Island" formerly used for ore mining, later destroyed through an eruption of the volcano and nowadays only used for seismological and other antarctic science stations.

enjoy, credit goes to an old friend of mine from Switzerland.

Philopek, thank you for sharing these images with us. Deception Island would be one of the destinations I'd like to visit if I ever travelled into that area. The pictures look so weird, strange and unnatural. I think, if somebody would have invented such an island for a adventure story many people would say "This map, this island, this bay is completely unrealistic".
Did you know that the crater bay allows tousists from time to time to have a swim? The still active volcano beneath it heats up the water temperature.

Could Deception Island be the remnant an impact crater?

It  would be nice to ban the Antarctic area for tourists. Otherwise this last 'pristine' place will be spoiled and contaminated fast.

always those extremes, which BTW is why there is war on this planet.

why can you guys never consider a healthy middle-way?

why banning, why not implementing quotas, limitations by time of year, number of vessels, size of vessels, mooring allowed or not number of people, etc. etc.

bans are never a good solution, why should we keep the planet intact if we cannot live on it to protect it? I restrict sugar, alcohol, meat, and many other inputs but would never BAN just for the sake of feeling just or great. i love sweets, hence i consume sugar, but not more than 12g average per day (not counting LOL) it's a irrelevant example but at least one.

people who opt for extremes in the name of the good have often in the past been the soil and ground for later huge conflicts. Consider that !

And then sometimes i consider to make donations to some of the loudest poor who demand to get back to the roots with our life-styles and see how long their restrictive life-style continues with a few thousand bucks in the drawer on in the account. i'm sure in 99% of all cases not as long as they thought while being poor. What I'm saying is that it's easy to buy nothing if one has no money, while for someone who loves all the crazy fast and expensive toys like myself it's really hard to say no if it's possible to say yes. I say this just to share the view from another angle.

IMO those with extreme view ultimately get nowhere, not even to the point that would be as good is one can get, because opposition tends to take a stance and lose readiness for compromise if the demands are to one sided and/or too restrictive. Like so often the best possible lays in the middle and if we do not want to seek the perfect middle-way, there remains nothing but to reduce world-population and now someone tell me how that should work without uproar all over the place (or dictatorship)

SOLOMON IS GREETING, become wise and smart, not demanding the impossible, just to appear to be a nice and just person, with a collapse at the very end as seen and suffered so many times in the past. Bragging with being nice has the same root like bragging with a big car or other stuff, it's a form of self-profiling that ends in the exactly same disaster like any other form of it. Think about all the evil that has been and still is done in the name of "GOD" just to have a nice sounding motive to perform all the ego-centric evil things.

To stay on topic, here come the next series of images, perhaps the last ones because "Cape Hoorn" is at the very edge of what can go through as the arctic if not beyond and without my tourist friend, there would be no images to post.

Images are made in the "Drake Passage" around "Cape Hoorn" at the most southern tip of the South American Continent.

why banning

'Why not banning' seems the logical question to ask here.

Answer: So that some (privileged) rich folks can go there for the giggles and pollute there also.

Now, why would someone other than that tiny group want it?

What a great picture blumenkraft! It looks like a polar bear is sitting on top. Maybe it is on holiday ;)

It is important to have very few 'wants'. You can train yourself and the easiest way to do that is to become material/money-poor.
Sometimes I walk into a supermarket with the intention to buy some nice snack but every time I just wander around and can't think of anything.
Not watching/listening to ANY advertisements makes you much less vulnerable to the temptation to buy.
Discipline!

why banning

Dear philopek, not to start a discussion in this thread, but a ban on tourists for nature reserves is not going to lead to war. I think you are a bit overreacting.
Tourism is an insanely destructive commercial enterprise. Responsible for enormous carbon footprints and lowering of quality of life for many people that live in old cities and elsewhere. Their living place is changed for the worse because of local government and commerce demands. People from far away are apparently more important than the people who actually live there. Tourism is one of the reasons that I moved out of Amsterdam. All character has gone. The same happened to the small city where I was born "Franeker": Destructive changes to lure the tourist to make money. As if local government is a for-profit business.
Nobody needs a non-local holiday. Tourism didn't exist before 1900. It has to go. Also non-commercial tourism for very rich people on their private yachts.
Pristine places on Earth are dwindling into non-existence. Antarctica is one of the very last ones. Tourism will spoil it. Leave the penguins and whales alone please.

I propose another ban: No fishing around Antarctica. None.

End of off-topic.

Nanning - while I very much get your point about tourism causing environmental and social problems, please don't bend facts to serve opinions. It made me continue the OT streak.
https://en.m.wikipedia.org/wiki/Tourism (https://en.m.wikipedia.org/wiki/Tourism)
Travel for leisure already existed in 1500BC. Large scale tourism in 1600 (Grand Tour of Europe), mass tourism with the railroads.
It's true though that tourism (and its damage) has been on a sharp growth curve in the last century. And that the rich have always been touring more than the poor.

Post by: nanning on February 11, 2020, 06:55:23 PM
I'm sorry that you think I am bending facts oren. I stand by my opinion and give a short reply here to not derail this thread.

How many very rich were in the world before 1900? That year is not meant to be exact, sorry. I'd have thought others would understand what I mean, seeing the enormous explosion of rich people since 1900. Now we have rich countries where most people are rich (enough).
I don't count those pre-1900 rich people's travels, adventures and exploration as tourism.
I have many more things to say about this because it is part of my understanding (from research) of why our society is as it is. All the new rich people wanting to copy the insane behaviour of the aristocracy because that is seen as 'the good life'. The insane hobbies of aristocrats are now normal behaviour. e.g. Owning a private car, mowing the lawn, tidiness, pet dogs.
I know you will likely disagree dear oren. I wish I could talk with you in real life.

From your link: "undertaken by mainly upper-class European young men of means"  (Grand Tour)

My last off-topic post on this subject in this thread. My apologies for starting this.

I would ban banning, and not preoccupy myself over other's possessions. This is off-topic & we need more awesome pics, so do not reply - discipline!
