%X Group of tourists (with park guides at the back) on what was then (1988) the bridge over the Clearwater Cave river in the Gunung Mulu National Park and World Heritage Site (Sarawak). The bridge was designed to float in high water but after around 10 years, with rot setting in and damage in a flood, it was deemed too dangerous to use. (Photograph by Jerry Wooldridge.)

%T The Wenlock Edge, Shropshire: England's least-known karst?
%9 Paper
%A Mick Day
%X Not previously recognized as significantly karstic, the Wenlock Edge and adjacent View Edge are escarpments of Silurian limestone that constitute a restricted fluviokarst landscape in south Shropshire, UK. Although no enterable caves have been documented, there are a small number of shallow dolines and small, disorganized karren. There are extensive valley networks, particularly on the dip slopes; some of these are usually dry but others have intermittent spring-fed drainage. The chemical signatures of the spring water, particularly in Ape Dale, are indicative of ongoing carbonate dissolution. Karst development is restricted by the limited autogenic recharge area and the absence of allogenic inputs, but the hydrology is distinctly karstic and the springs have both historical and contemporary significance. The area might merit further investigation.

%T Pre-mineralization vadose scallops associated with hematite at Hodbarrow, South Cumbria, UK.
%9 Paper
%A Phillip Murphy, Max Moseley
%X The origin of 'pocketing' that has been observed on the walls of some mined-out hematite ore-bodies in the Morecambe Bay limestones was unclear. These morphological forms have sometimes been interpreted as a result of metasomatism but the known existence of cavity-fill deposits associated with the replacement ores suggests that they might instead represent fossilized pre-mineralization dissolution features. Examples preserved beneath hematite fill in a disused quarry at Hodbarrow, Cumbria, are clearly scallops. Morphometric analysis shows a mean boundary shear velocity of 1.1 metres per second at the time of formation. This is consistent with vadose flow in a karstic aquifer. The feasible age range of the mineralization episode, together with the known geomorphological history of the district, points to a late Carboniferous - early Permian date for the scallops.

%T On tourism in tropical karst.
%9 Paper
%A Mick Day, Andrea Hall
%X Tourism is a very significant human activity in tropical karst landscapes, with global annual visitor numbers probably exceeding 40 million. Particularly heavily visited locations include Guilin and the Lunan Stone Forest in China, Ha Long Bay in Vietnam, the Batu Caves of Malaysia, and the Caribbean coastlines of the Yucatan Peninsula, Jamaica and other islands. These levels of tourism have wide-ranging societal and environmental implications, but these have not received the attention that they warrant. Whereas much tourism is incidental to the tropical karst landscapes, some is karst-specific and merits particular attention.

%T The response of Gammarus pulex to fine sedimentation and vertical hydraulic exchange: an experimental investigation.
%9 Paper
%A Kate L Mathers, Paul J Wood
%X This report outlines the effect of sedimentation and vertical hydraulic exchange (upwelling versus downwelling water) on the distribution of the freshwater shrimp, Gammarus pulex, in experimental benthic and hyporheic sediment columns. The results demonstrate that the distribution of individuals was markedly different in experiments subject to upwelling and downwelling flow and that as the volume of fine sediment within the benthic and hyporheic sediments increased, the number of G. pulex individuals within the hyporheic zone was reduced.

%T The visit of Lieutenant Walter Stanhope Sherwill (1815-1890) to Cango Cave, South Africa, on 9 November 1840.
%9 Paper
%A June M Harvey, Stephen A Craven
%X An account is given of the 1840 visit of an Indian Army officer who spent his long leave in the Cape Colony. This paper elaborates on his published description of Cango Cave, with additional comments on the geology of the area, and on the subsequent publicity that encouraged visitors during the following half century.
