The book “Hypogene Karst Regions and Caves of the World” is going to be published by Springer, in its series “Cave and Karst Systems of the World”.
There will be a karst session at the AGU Fall 2016 Meeting in San Francisco, USA in December 12-16: Characterization, Modeling, and Remediation of Fissured, Carbonate, and Karst Groundwater Systems
A book "Höhlen und Karst in Österreich" (Caves and karst in Austria; Editors: Christoph Spötl, Lukas Plan & Ehrad Christian) will be printed until mid of July. Subscription is available.
Many inspiring ideas on caves can be found in images created by children, generated by the International Contest of Kid’s Drawing "Caves in the Eyes of our Children".
A call to submit an abstract to a session devoted to karst aquifers, which will be held in September in Montpellier during the 43rd IAH Congress

That paleomagnetism is natural remanent magnetization preserved in rock sequences. during rock deposition magnetic minerals are aligned according to the direction and polarity of the earth's contemporary magnetic field. after movement of the magnetic poles, or periodic reversals of polarity, the remanent magnetization is preserved in the rocks and may be measured to aid identification of stratigraphical units and to assess their relative ages .?

Hypogenic speleogenesis is the formation of solution-enlarged permeability structures by waters ascending to a cave-forming zone from below in leaky confined conditions, where deeper groundwaters in regional or intermediate flow systems interact with shallower and more local groundwater flow systems. This is in contrast to more familiar epigenic speleogenesis which is dominated by shallow groundwater systems receiving recharge from the overlying or immediately adjacent surface. Hypogenic caves are identified in various geological and tectonic settings, formed by different dissolutional mechanisms operating in various lithologies. Despite these variations, resultant caves demonstrate a remarkable similarity in patterns and meso-morphology, which strongly suggests that the hydrogeologic settings were broadly identical in their formation. Hypogenic caves commonly demonstrate a characteristic morphologic suite of cave morphs resulting from rising flow across the cave-forming zone with distinct buoyancy-dissolution components. In addition to hydrogeological criteria (hydrostratigraphic position, recharge-discharge configuration and flow pattern viewed from the perspective of the evolution of a regional groundwater flow system), morphogenetic analysis is the primary tool in identifying hypogenic caves. Cave patterns resulting from ascending transverse speleogenesis are strongly guided by the permeability structure in a cave formation. They are also influenced by the discordance of permeability structure in the adjacent beds and by the overall hydrostratigraphic arrangement. Three-dimensional mazes with multiple storeys, or complex 3-D cave systems are most common, although single isolated chambers, passages or crude clusters of a few intersecting passages may occur where fracturing is scarce and laterally discontinuous. Large rising shafts and collapse sinkholes over large voids, associated with deep hydrothermal systems, are also known. Hypogenic caves include many of the largest, by integrated length and by volume, documented caves in the world. More importantly, hypogenic speleogenesis is much more widespread than it was previously presumed. Growing recognition of hypogenic speleogenesis and improved understanding of its peculiar characteristics has an immense importance to both karst science and applied fields as it promises to answer many questions about karst porosity (especially as deep-seated settings are concerned) which remained poorly addressed within the traditional epigenetic karst paradigm.
