22 novembre 2007 – video e kit didattici

Sul sito educational di ANDRILL, quello ufficiale internazionale, che si chiama “Project Iceberg” son stati pubblicati recentemente due nuovi video: uno sulla gelogia dell’Antartide e uno sulle esplorazioni del continente.

Megan Berg è l’autrice di questi video e di tutto il materiale che trovate sul sito che è TUTTO di straordinaria qualità. I video saranno disponibili in futuro anche sottotitolati in italiano.

A proposito di video sottotitolati: si sta finalmente concludendo la telenovela dei kit didattici per le scuole. Son già e imbustati e pronti per raggiungere le 28 scuole, manca solo una brochure. Prima della fine del mese partiranno: vi do la mia parola di boy scout.

16 novembre 2007 – OlÈ

Continua la cavalcata della trivella di ANDRILL nelle rocce antartiche.

Dopo le difficoltà dei giorni scorsi determinate dalle avverse condizioni meteo, (vedi cronaca) sono ripresi a pieno ritmo i lavori di perforazione e carotaggio.

La profondità attuale della testa della trivella è 819 metri, considerando gli strati di acqua (300m) e ghiaccio (80 m) soprastanti siamo ad una profondità complessiva di quasi 1200 metri dalla superficie.

Pochi giorni fa durante la videoconferenza con l’Antartide (vedi sotto) ci sono state spiegate da Davide le scoperte, le gioie, gli entusiasmi e le difficoltà che un progetto del genere comporta. Alla fine ci siamo guardati uno con l’altro e ci siamo scoperti a tifare per quel gruppo di persone che sta lottando quotidianamente in questa avventura.

E allora olè trivella olèolè!

15 Novembre 2007 – In diretta dall’Antartide

Ieri si è svolta la prima videoconferenza del 2007, tra l’ITIS Buonaroti di Trento e gli italiani del progetto ANDRILL che si trovano alla base antartica americana di Mc Murdo. Sono state 2 ore di lavoro fitto fitto in cui Davide Persico, il ricercatore della Università di Parma ci ha fatto il punto delle attività di ricerca e di perforazione.

E’ stato un pò un tiro incrociato di domande da parte sia degli studenti della classe di progettosmilla che delle altre due classi. Si è parlato di datazione, fossili, ghiaccio marino, delle operazioni di taglio e analisi delle carote (ce ne ha fatta vedere una in diretta), dei problemi causati dalle cattive condizioni meteo, ma anche della vita quotidiana alla base. Insomma due ore intensissime di lavoro per noi e per lui.

Su la mano chi sostiene che le videoconferenze sono solo una inutile esibizione di tecnologia senza alcun valore….

>> SI PARLA DI ANDRILL


Il bimestrale di Scienza “Darwin” dedica un lungo ed interessante articolo alla ricerca ANDRILL. L’articolo è scritto dal capo scientifico: Dott Fabio Florindo, una vecchia conoscenza di progettosmilla che ha partecipato a diverse iniziative, tra cui anche alcune videoconferenze tenutesi l’anno scorso, in diretta dall’Antartide.

>> UN QUARTINO DI SCUOLE


In questi giorni è stato raggiunto e superato il numero di 25 scuole iscritte a progettosmilla.it.

Pensavamo meritasse di essere festeggiato.

25 scuole sono un quarto di 100, una goccia negli ettolitri delle oltre 10 mila scuole italiane, una quantità minima, ma la qualità è eccellente…. Hai presente quel vino robusto che ti fa digerire subito e pensare che forse potresti di tornartene a casa con una bottiglia sottobraccio? Ecco quel vino sono sono le 26 scuole di progettosmilla.it. Sono distribuite in 14 province italiane di 11 regioni con 876 studenti coinvolti e gli accessi al sito che ad Ottobre hanno superato i 3500 accessi, il doppio dell’anno scorso.

Roba da far girare la testa.

>> CARTELLE RISORSE – Aggiornamento Tema “Antartide: uomo e ambiente”

In questi giorni mi son imbattuto in alcune risorse che possono essere di grande utilità alle scuole che stanno lavorando al tema “Antartide: uomo e ambiente”. Le ho messe in una cartella e accompagnate da una piccola descrizione. La cartella si scarica e si apre con le stesse modalità della cartella risorse principale. E’ un pò pesante (20 Mb) ma ne vale la pena….

M. Monroe of Antarctica

Have you ever met with those black and white photos shot during Marilyn Monroe’s visit to American troops in Vietnam? If it happens to you, take two minutes to look over them: she is wearing a short chenille jumper, she has got short and curly hair, a porcelain skin and a changing smile… all the requisites to be a Venus at that time and not only… The soldiers are fanning out around her, quite close to the photographer too, so that you can look at their faces: heads stretching in every direction, pale-blue, with short and very tidy hair, wide open eyes, emaciated but smiling faces.

It is a perfect moment, come out of the photomagician’s top hat. It talks about men in an infernal circle, about their impulses, sure, but also about their very human desire of normality and beauty, that, at least for a while, can snatch them from a too hard routine. She, Marilyn, slung there, in the Asiatic jungle, directly from the USA. Continua la lettura di M. Monroe of Antarctica

GROUND MEANS

Lots of you ask me news about the base, everyday’s life and the relation with the environment. I do have many things to tell you, trust me, and I have got a lot of material too, I just lack some time to publish it. Moreover yesterday we started to work in the laboratories and for 4 hours a day we help researchers in their analytical job on cores. But be quiet: I will find time anyway. Today, for instance, I would like to open a particular window about life at the base. Do you want to understand the connection between man and his environment? Let’s start from an unusual point of view. Let’s do like this: we will observe at close quarters the means used in ground shifts, the ones they use here everyday.

The antarctic equivalent of our buses, utes, undergrounds and motortrucks that we have use and fight daily. Have you ever guessed? Perhaps a new idea will raise from the environment and, why not, also from the men that built and now drive them.

They impressed me at once, all of them. As soon as I reached the base. It seemed to me as if I was in a fun-fair where everybody tries to outdo each other in driving the oddest means. Each one queerer than the other, that would stir everybody’s imagination: long and tall spiders, big lizards with huge eyes, wide and very flat turtles, iguanas with a long muzzle…. only the thought to classify them causes a headache.

But all, without distinction, have one thing in common: a cable, with a dangling tap coming out of the front bonnet. There is an electric circuit heating the engine in the parks, that, as you can see, are all equipped with current.

As far as I know I am not the only one suffering cold.

TRIP TO CASTLE ROCK

Saturday evening, in the laboratory, before a pc. At about 8 p.m. I try to remember the last time I turned it off, but I don’t manage. Bad sign. After a while, Julian, my New Zealand teachmate, comes in with an uncoded, catatonic look. We look at each other, we laugh and (maybe) we do not even say. Silently we go out of the laboratory and we know: tomorrow we are going to Castle Rock.
The environs of Mc Murdo offer good chances to have some brief healthy trips. There is only one problem: here we are in Antarctica. It counts little if you live in the most equipped and comfortable base of the continent; as soon as you go out, it is the master. And, we have understood, it does not joke. During recreational activities, accidents, due to different causes, are not unusual. Some of them, unfortunately, did not have a happy end. In order to solve the problem, rigid rules were established.

One: whoever goes in for outdoor activitites has to follow a specific course (just 3 hours).

Two: before the departure, you have to state the exact data (way, start, arrival, participants etc.) in a dedicated area of intranet, the informative net of the base.

Three: right before leaving the base, you have to go the firemen’s barracks for the final permission, given according to the weather forecast, and for the emergency radio.

At about 11 o’clock, we succeed in finishing the scheduled liturgy and, dressed like divers, we walk towards Castle Rock: a rocky formation emerging in the middle of Ross Isle, at 5 km from the base. It is the longest route and during the return we reach Scott base: 16 km, 6 forecast hours. After half an hour walk and a brief stop in an emergency refuge (called “the apple”, for its shape and colour), we reach Castle Rock. We feel well and we decide to go along the road towards the top.

And we do well. The top is flat and without snow, the rock is brick red, porous and friable, with big fragments of black rock, many of which vacuolar. I pronounce the name Franco told me: ‘ialoclatsiti’. Probably, the fruit of a remote lave flow in the ice. We look around and we find nothing like what we have seen before.
Heavy and low clouds quickly follow the profile of the volcano Erebus, parts of others, taller and more laminar, draw shadows moving over the ice towards a horizon that joins white and azure in every possible way, according to the direction you look at: white/azure, white/sky-blue; white/white… We sit down. We stay and watch silently for half an hour, just like we did a few hours before in the laboratory. Then, lazyly, we take our cameras and take some shots. In the meanwhile, the wind is blowing, rather convincing in inviting us to descend and we do not take much persuading.

THE SNOW – Sunday, 29th October 2006

Two nights ago it snowed. They were thin and microscopic flakes. I let them fall on my jacket to watch them better. They were infinitesimal points. The most expert asserted that they were not carried by the wind, but new, just shaped. Right before sleeping, I looked out: there was a layer of 3 cm, light like a veil. The following morning there was no more sign of it, not even in the most sheltered places. Everything was like before, as if nothing had happened.

Since we were children, we learned to associate the idea of cold with that regarding snow; the colder it is the more abundant it snows. Then, at school you learn that Antarctica is the coldest continent of the world and in a moment you begin dreaming about how much snow it can fall there: 3, 5, 10, 100 metres of snow, insurmountable and massive walls by which you invent impossible exploits shortly before falling asleep in the rainy nights of March. The very moment of the year you have to put aside definitively the expectation for new snowfalls.

“In Antarctica that does not happen..” you think, “..in Antarctica children are always happy; they watch so much snow falling down!” But it is not so.

In Antarctica it falls far less snow than you usually think. On the coast a little more, but on the inland very little: the equivalent of 2,5 cm of water. It is surely less than that on the top of our Alps. What is very strange here is that snow, simply, does not melt.

Never.

Here the life of a snowflake does not resemble our home-grown snow. Instead, it is like the grains of sand in the desert. It falls, sure, but then it rises, thanks to very violent winds, it travels along boundless distances, beats against stones and rocks, frosting them like glass, it mixes with grains of sand, then, sometimes, it settles, in order to rise again and continue its pilgrimage.

Melting, a fancy, that is clear, but it can be entrapped and accumulated under other snow. At that moment it starts getting compact under the weight of overhanging snow, flakes get closer and the empty spaces reduce until, after about one thousand years and at about 80 m deep (Italian-French project EPICA), it becomes real ice, solid, very hard. That is its destiny, but only more immediate, as it has not come to an end yet.

Ice does not stay still; it moves radially from the centre to the exterior, just where it has to go: to the ocean, where else? But it arrives slow, very slow, in a surreal slowness, exasperating, irritating. Hundreds of thousands years. Hundreds of thousands….I do not know what you think about, but slowness arouses dread, awe, respect, much more than speed… slowness evokes the cosmos, that cannot be stopped. It manages to make useless and a little droll the rest, man and speed included.

Maybe proceedings here are like this, in this bubble where everything is broadened, expanded and where a simple cycle of light is spread on 365 days.

Antarctica! Sunday – 22th October 2006

Antarctica! Here I am, I am here, no doubt. Sometimes I feel a little giddy, I let myself to be carried by a voice telling me “It is not true, it is not true!”, then it is enough to go out and breathe some fresh air and the one out there waiting for me brings me to reality…. If they call cold what I have known till now, here they should call it another way. I do not know how, maybe ipercold, ultracold, freeze or, better, you should find a new name, like antarctice. If you have any suggestions, please send me. It is an important matter.
Yesterday it was -29°, without considering the wind. I look for a sign letting you know, the clearest way, what means lesstwentyninedegrees and I find it at once: the doors! I think you recognize something familiar in the photo. Have you ever entered the kitchen of a restaurant or the backs of some butchers’ shops? No? Well, try; you will find cold stores. Places for the preservation of food at several degrees. About twenty years ago in every house there were freezers with a hook. They are still trendy and you can find them in some glamour houses on retrò freezers. Here in Antarctica the doors are like those ones. And I assure you they are not there for show.
They say during the first days you suffer more because the organism has to accustom itself. Well, I say: let’s hope so as, for the moment, I admit, I quite suffer cold… It seems to me there is really nothing you can wear to feel a little better and leave the cold out of your body, far away. I can try to wear one of those doors…
Up to now, in two days stay at the base, I have been out there, in all, a quarter of an hour, not more. I assure you it is sufficient and more than that. Every time Continua la lettura di Antarctica! Sunday – 22th October 2006
