Höhlenforscher-Motivation – Die innere Triebfeder

Willi Grimm

Review of my 25 years of speleology (1963-1988), taking into account
the unconscious motivation to do so. It features the period before, as
well as the reflective review after this quarter of a century of active caveing.
Including astrological and psychological aspects.

Motivationen zur Höhlenforschung

Thomas Kesselring

Was zieht Menschen in Höhlen? Wie erklärt sich die jahrelange Begeisterung für Höhlen bei der Speleo-Spezies? – Ich will hier ein paar Motive oder Motivations-Gründe diskutieren, die spezifisch sind für die Höhlenforschung im Gegensatz zu anderen Sportarten oder anderen Betätigungen. Das Thema wollen wir mit Hilfe einer Fragebogenaktion am Kongress Sinterlaken weiter erforschen!

About the use of the calcFlow-Method in ice cave research

Christiane Meyer

Since 2006 the working group “„Climatology of Extreme Environments“ at Ruhr-University Bochum is conducting climatological studies in Schellenberger Eishöhle at Untersberg (Berchtesgaden Alps). In the course of the research activities the work was repeatedly limited due to the energy supply at the study site. Over the years more and more questions arose during data analysis, which we could not clarify with our standard methods. Since these difficulties also exist at many other ice cave sites, we began to develop the calcFlow method in the course of my dissertation, which uses air temperature measurement to determine the airflow in the ice cave. In the presentation we present the method as well as first results of the determination of the energy balance of one passage section.

Langzeit-Temperaturmessungen in der Schrattenhöhle

Martin Trüssel

Since 1990 cave air temperature has been monitored in the Schrattenhöhle, which has a total length of 20 km and an altitude difference of 570 m. In this sub-alpine to alpine cave, situated in central Switzerland on the northern rim of the Alps, four instruments, placed at 150 m elevation intervals, log the cave air temperature at 1 hour intervals.

Felstemperaturen im Hölloch-Silberen-Gebiet

Ulrich Joering

This study examined a systematic approach of temperature measurements of the karstified mountain range of Hölloch-Silberen, which covers an area of approx. 4 x 10 km. The measurements show, that rock temperatures near the entrance of caves are generally a few degree °C cooler than the annual average air temperature. It is interpreted, that the cold melt water flux in spring and cool air circulation decreases large areas of caves and their surrounding rock mass. Negative temperature gradients with increasing depth were observed in the Hölloch cave due to the combination of several water flowpath from catchments at different altitudes. The comparison of daily air temperatures at different altitudes with the cave temperatures (of rock and air) allowed some tentative conclusions about the driving forces of diurnal air flow in a large cave system.

Observations de temperatures et de niveau d‘eau

Patrick Dériaz

Cinq cavités de Suisse romande ont été équipées du système Cavelink : grotte de Môtiers, grottes de Vallorbe, réseau de Covatannaz, la source de la Chaudanne, et la source du Jaun. Des mesures de température et de niveau d’eau sont effectuées depuis plusieurs années. Des comparaisons sont effectuées entre les cavités. La variation de température de l’eau à la Grotte de Vallorbe est de plus de 10° entre l’été et l’hiver.
