Annual glaciological survey of Italian glaciers (2023)|Campagna glaciologica annuale dei ghiacciai italiani (2023)
No full textChiarle M., Bondesan A., Carturan L., Scotti R., Annual glaciological survey of Italian glaciers (2023). (IT ISSN 0391-9838, 2024). Results of the 2023 annual glaciological survey conducted on Italian glaciers are here presented. About two-hundred volunteers, assisted by numerous collaborators, operated last year in the three Alpine sectors (Piemonte - Valle d’Aosta, Lombardy and Triveneto) and in the Apennines (Calderone Glacier, Gran Sasso Group) observing two hundred and nine glaciers. One hundred and thirty glaciers were observed in the Piemonte - Valle d’Aosta sector while frontal variation was measured at the snout of fifty-nine glaciers. Twenty-nine and fifty glaciers were visited in the Lombardy Sector and in the Triveneto Sector, respectively (twenty-two and forty-three of which were measured, respectively). Mass balance measurements were conducted on nineteen Italian glaciers during the 2022-2023 hydrological year: four glaciers in the Western Alps (Piemonte - Valle d’Aosta sector), fourteen in the Eastern Alps (three in the Lombardy Sector, the other glaciers in the Triveneto Sector) and one in the Central Apennines
Ruote e nel deserto. Teatri operativi, mobilità e logistica del Regio Esercito in Africa Settentrionale
No full textIl volume, incentrato sulla storia degli Autieri del Regio Esercito in Africa Settentrionale e sulle problematiche della mobilità e della logistica in quel teatro, trattando antologicamente una vasta serie di argomenti in buona parte inediti, si compone di due parti.
La prima parte, dopo una descrizione geografica che spazia dal fronte di El Alamein a quello tunisino, illustra le infrastrutture del territorio, con approfondimenti sulla navigazione desertica e sulla cartografia della regione.
La seconda parte, vertendo sulla storia degli Autieri dagli albori della motorizzazione all'impiego operativo, tratteggia l'organizzazione logistica e le caratteristiche dei mezzi impiegati in Africa Settentrionale fino al termine della campagna.
Completano il testo un elevato numero di schede di approfondimento storico e tecnico, testimonianze dei combattenti, tavole a colori dei mezzi, cartine e disegni inediti. Sono infine pubblicate numerose foto dell’epoca, molte delle quali inedite
Monitoring the snouts of local glaciers around Terra Nova Bay Station, (Victoria Land, Antarctica).
No full textHere are describe the frontal fluctuations of small local glaciers in the Tera Nova Bay area (Northern Victoria Land, Antarctica). The goal was to compare variations with environmental parameters and to establish a correlation between climate change and glacier behaviour. Althought small variations in the position of the snout of monitored glaciers have been observed, glaciers are in a steady state and there are no substantial change in their mass. The equilibrium is confirmed for long periods if we compare the present state of glaciers with their morphologies from aerial photographs fromthe 50s and 60s
WWI MILITARY USE OF CAVES IN THE CLASSICAL KARST OF NORTHEASTERN ITALY
No full textThe area of the Classical Karst in Northeastern Italy was involved during the Great War by a series of military actions known as "the Twelve Battles of the Isonzo". The knowledge of the karstic landscape and its fea-tures clearly represented an advantage in military operations. A well-con-solidated theoretic military geological preparation led armies to exploit for warfare purposes natural morphologies, such as caves, sinkholes, fault scarps and dry valleys; many artificial modifications were apported to the hypogean and epigean landscapes to adapt landforms to military purposes. Human-made tunnels, walls, stairs, floors, built with concrete and/or rocks found onsite, served to the realization of complex defensive systems, whose strategical importance was newly re-discovered in recent times. Two hundred and twenty natural caves have been mapped in the Italian Classical Karst that were used in wartime, to analyze their utiliza-tions and geographical distribution. Most caves were used by soldiers as shelters, representing a safe natural environment during enemy artillery bombings. Several other purposes reveal the complexity of artificial ad-aptations and planning in construction works. Water reserves, electrical stations, command posts, ammunition depots are only few examples of the natural exploitation offered by caves. We investigate six Austro-Hun-garian military caves from various locations along the frontline, describ-ing their different artificial modifications and geological features. The Classical Karst not only represents a globally known key site for the study of karst geomorphology, but is also one of the most iconic traits of warfare on the Austro-Hungarian front during WWI
Annual glaciological survey of Italian glaciers (2022)
No full textResults of the annual glaciological survey (2022) conducted on Italian glaciers are here presented. About 250 volunteers operated last year in the three Alpine sectors (Piemonte - Valle d’Aosta, Lombardy and Triveneto) and in the Apennines (Calderone Glacier, Gran Sasso Group) observing two hundred and two glaciers. One hundred and eighteen glaciers were observed in the Piemonte - Valle d’Aosta sector while frontal variation was measured at the snout of sixty glaciers. Twenty-seven and fifty-seven glaciers were visited in the Lombardy Sector and in the Triveneto Sector, respectively (twenty-one and forty-three of which were measured, respectively). Mass balance measurements were conducted on seventeen Italian glaciers during the 2021-2022 hydrological year: four glaciers in the Western Alps (Piemonte - Valle d’Aosta sector), twelve in the Eastern Alps (three in the Lombardy Sector, the other glaciers in the Triveneto Sector) and one in the Central Apennines
THE GEOMORPHOLOGICAL CONSTRAINTS OF THE ITALIAN/AUSTRO-HUNGARIAN FRONT IN THE DOLOMITES DURING THE FIRST WORLD WAR
No full textMany documents within the enormous historiography of the First World War on the Italian Front highlight the importance of physical geography, yet specific and systematic studies of the influence of morphology on war in the Alps are scarce. Geomorphology influenced the battles that occurred on the main passes in the Dolomites. Geomorphological and military history maps were created for four of the most important areas on this front. The steep and high valley sides, part of the unique geomorphological setting of the Dolomites, determined unassailable positions from which the defenders, with protected and sometimes relatively accessible rear lines, could control and hinder enemy transit through the valleys by use of crossfire. From this point of view, the alpine terrain, as the result of the morphogenetic processes that took place in the region, can be considered as one of the key geographical aspects that controlled the conduct and the outcomes of the fighting in the valleys and passes
