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 tubular passage; tube; tube passage is 1. cave passage formed by approximately equal dissolution all round when full of flowing water within the phreas. relict tubes, abandoned as the water table was lowered, are common in old caves, and may be partially filled by sediment, breakdown or stalagmite, or entrenched to form keyhole passages. tube sizes range to over 15m in diameter, but the larger ones are rarely of uniform section. peak cavern in derbyshire is well known for its fine circular phreatic tubes. some of the trunk passages of mammoth cave, kentucky, are spectacular tubes of elliptical section, formed by dissolution rates that were higher along the bedding than across . 2. these are nearly horizontal cave passages (tunnels) with round or elliptical cross sections and are either straight or winding. at mammoth cave they vary in size up to 30 feet high and nearly 100 feet wide. they are formed while completely filled with flowing water. whereas they are typically wider than high as a result of dissolution along horizontal cracks and beddingplane partings, they may also form as high, narrow, straight fissures along major vertical or near vertical fractures . see also canyon passage; keyhole passage; passage; vertical shaft.?

We report the first incision rates derived from burial ages of cave sediments from the Mur river catchment at the eastern margin of the Eastern Alps. At the transition zone between the Alpine orogen and the Pannonian basin, this river passes through the Paleozoic of Graz — a region of karstifiable rocks called the Central Styrian Karst. This river dissects the study area in a north–south direction and has left behind an abundance of caves. These caves can be grouped into several distinct levels according to their elevation above the present fluvial base level. Age estimates of abandoned cave levels are constrained by dating fluvial sediments washed into caves during the waning stages of speleogenesis with the terrestrial cosmogenic nuclide method. These ages and the elevations of the cave levels relative to the current valley floor are used to infer a very complex history of 4 million years of water table position, influenced by the entrenchment and aggradation of the Mur river. We observe rather low rates of bedrock incision over the last 4 Ma (in the order of 0.1 mm/y) with an e-folding decrease in this trend to lower rates at younger times. We relate this incision history to a tectonic setting where an increase of drainage area of the Mur river due to stream piracy in Late Miocene to Pliocene times is linked to surface uplift. The later decrease in valley lowering rates is attributed to the rise of the base level related to aggradation of sediments within the valley. Sediment transport through the valley from the upstream section of the Mur river limited the erosional potential of the river to a transport limited state at the later stages of the incision history.
