The International Workshop on Ice Caves
On days 30 September and 1-2 October 2013, a 7.8 m long ice core has been extracted from a permanent ice cave deposit in the Southeastern Alps (Vasto’s cave, Mt.Canin - Julian Alps). Each 20 to 100 cm long section of the ice core have been immediately stored in plastic bags and preserved thanks to dry ice. The ice samples, thanks to the helicopter, has been subsequently brought on valley and promptly stored in a refrigerated van, made available by BoFrost. Thus the ice cores has been transported intact to the EUROCOLD laboratory in Milan. These operations have been carried …

Time, Money, And Melting Ice: Proposal For A Coopertive Study Of The World’S Cave Ice In A Race Against Climate Change, George Veni, Lewis Land, Aurel Perşoiu
The International Workshop on Ice Caves
Climate change is a global phenomenon that is melting and threatening to melt ice deposits in many of the world’s ice caves. The National Cave and Karst Research Institute of the USA is concerned that major and important paleoclimate and paleoenvironmental records stored in cave ice will soon be lost, and is proposing an international collaborative effort to overcome funding and logistical challenges to sample and analyze at least a representative collection of ice from several regions before further melting occurs.

The International Workshop on Ice Caves
Welcome to the Sixth International Workshop on Ice Caves (IWIC VI) in Idaho Falls, Idaho, USA. The National Cave and Karst Research Institute is pleased to host the first IWIC to meet outside of Europe, which will include speakers from over half a dozen countries in Europe, Asia, and North America. The conference setting in this mountainous region of the northwestern United States will provide conference participants with multiple opportunities to visit ice caves, including two trips to Craters of the Moon National Monument. This is also the first IWIC to examine ice in lava tube caves.

Climate Study In An Abandoned Auto Tunnel In Alaska, Usa, Andreas Pflitsch, David Holmgren
The International Workshop on Ice Caves
An abandoned auto tunnel in south central Alaska in an elevation of 118 m above sea level seemed to be a perfect laboratory for studying the evolution of ice speleothems in a yearly cycle. More than 1,500 ice forms like stalagmites, stalactites, columns in various shape and arrangements, developed in just 2 month to a high up to 6 meters and lasted for another 5 to 6 month. In October just the remains of the melted ice in rings and rectangular patterns of a white powder could be found. Unfortunately the mostly sealed tunnel was opened in January 2014 by …

Some New Potential Subterranean Glaciation Research Sites From Velebit Mt. (Croatia), Neven Bočić, Nenad Buzjak, Zoltan Kern
The International Workshop on Ice Caves
Despite the frequent reports about their shrinkage detailed survey of the major subterranean ice deposits is still lacking in Croatia. Here we present cave maps and detailed description of cave ice accumulation from five caves of the Velebit Mt. Morphological constraints allowed ice volume estimation for four of them. Ice volumes were estimated as ~1500 m3 at the Gavranova Pit in 1999, 100 m3 at Štirovača ice cave in 1987, 150 m3 at Japagina 3 in 2000, 1500 m3 at Kugina ice cave in 2004. These new records provide reference data for future studies to evaluate …
Ice Caves On Extraterrestrial Bodies: What Are The Prospects For Speleogenesis And Detection?, Penelope J. Boston
Ice Caves On Extraterrestrial Bodies: What Are The Prospects For Speleogenesis And Detection?, Penelope J. Boston
The International Workshop on Ice Caves
Potential mechanisms for creating cavities in icy extraterrestrial bodies have been tentatively explored by several authors. On one hand we have examples of mechanisms that create caves in water ice here on Earth. In addition, there may be unique mechanisms on other Solar System objects that do not occur on Earth but might produce cavities, e.g. sublimation of comets upon perihelion passage. The methods of detecting such cavities depend upon the nature of the icy body in question, the potential for orbital or landed missions to visit those bodies in the future, and remote or landed methods for detecting the …
Internal Drainage Of Glaciers And Its Origin, Bulat R. Mavlyudov
Internal Drainage Of Glaciers And Its Origin, Bulat R. Mavlyudov
The International Workshop on Ice Caves
Ways of occurrence of elements of an internal drainage of glaciers and also origin of internal drainage systems as a whole are considered. It is shown that elements of an internal drainage can be formed either on the base of fissures and crevasses or by incision of water streams into ice from glacier surface. The basic way of glacier drainage is formed on the base of sliding plane which is formed closely to glacier bed and smooth all roughnesses of the bed. Spreading of water on the surface of this plane during spring time forms not effective drainage system however …

The Sandy Glacier Cave Project: The Study Of Glacial Recession From Within, Eduardo L. Cartaya
The International Workshop on Ice Caves
The Sandy Glacier Cave Project is a National Speleological Society (NSS) sponsored study on the unique system of glacier caves located on the Sandy Glacier on the western flank of Mt Hood, Oregon. While the study primarily targets the structure, layout and ice volume change of the ever moving cave system by conducting annual grade 5 surveys, numerous tangential observations and trends have been recorded that are of great interest to the study of glacial recession, watershed hydrology, micro-biology and astro-biology, as well as the study of organic specimens and remains being thawed out of the ice mass by the …
Numerical Modeling Of Formation Of A Static Ice Cave – Ningwu Ice Cave, Shanxi, China, Yaolin Shi, Shaohua Yang
Numerical Modeling Of Formation Of A Static Ice Cave – Ningwu Ice Cave, Shanxi, China, Yaolin Shi, Shaohua Yang
The International Workshop on Ice Caves
Ningwu Ice Cave in Shanxi province, China, is the largest Ice cave in China. We use Finite Element Method（FEM) to model the process of heat transfer in the ice cave. We not only calculate thermal conduction in spring, summer and fall, but also calculate the convective heat transfer in winter by introducing an equivalent thermal conductivity of cave air. Our computation shows that the ice cave can be formed within a decade, and reach a stable cyclic state in few centuries. Our calculation also shows that if people set a trap door at the ice cave entrance, especially in winter, …

Characterization Of Two Permanent Ice Cave Deposits In The Southeastern Alps (Italy) By Means Of Ground Penetrating Radar (Gpr), Renato R. Colucci, Daniele Fontana, Emanuele Forte
The International Workshop on Ice Caves
In order to assess the thickness and the inner structure of some permanent ice deposits in two high elevated alpine karstic caves of the Canin massif (Alpi Giulie, Italy), we performed several multi frequency Ground Penetrating Radar (GPR) surveys. The surveys have been conducted within the project MONICA (MOnitoring of Ice within Caves), aimed at the paleoclimatic characterization of the considered cave ice deposits. GPR surveys have proved to be crucial also in finding the most suitable place for carrying out a drilling core. This has been particularly useful in the Vasto’s ice cave (VIC) in which the direct/visual estimation …

On The Mechanism Of The Naturally Formed Ice Spikes, Hi-Ryong Byun, Chang-Kyun Park
The International Workshop on Ice Caves
The formations of the ice spike, which is the ice bar risen upward from the ice surface in bowl and has been known as a mystery of the Mt. Mai in Jinan, Jeonbuk Korea, are observed and analyzed through the observation records on more than 60,000 bowls of water for 8 years and 7 days and nights' consecutive meteorological observations. Experiments making the ice bar in the refrigerator have also performed. As results, it is verified that the ice spike is not a mystery but a naturally grown ice bar caused by the volume expansion centralized to a certain point …
