It has almost been one year since the relaunchof TheConduit last June. In 2009, the Karst Waters Institute circulated the newsletter to 760 people, and this issue will circulate to more than 800 cavers, students, karst scientists, and other folks in terested in the mission of KWI around the world! Among those individuals,27 countries are represented. This type of newsletter just takes word-of-mouth and pushing the sendbutton in an email. So, pleasecontinue to pass along TheConduit to your friends. We are especially interested in making sure that students (both young and old) know about KWI. This Conduit consist s of news from past KWI activities, including the Annual Awards Banquet in March, as well as a write-up from Dr. Alexander Klimchoukabout the 2009 HypogeneSpeleogenesisconference in the Ukraine. The preliminary announcement for the 2011 KWI-sponsored Carbonate Geochemistry : Reactions and Processes in Aquifers and Reservoirsis included, as well as information for future karst-related (and KWI co-sponsored) conferences in 2010 and early 2011. One of those conferences is the 12th Multidisciplinary Conference on Sinkholes and the Engineering and Environmental Impacts of Karst, which will be in St. Louis, Missouri. This issue of the Conduit also contains a special feature Where are they now ?, which details the research of two of KWIspast William L. Wilson Scholarship for Karst Science recipients, Lindsay Walker and Megan Curry. Both Lindsey and Megan graduated with their MS degrees within the past few years, and its great to read about their major research findings. The goal of the Wilson Scholarship is to attract and support new karst scientists to continue the research that Bill so deeply loved. In or der to continue funding worthy students well into the future and as a legacy of KWI and Bill, KWI initiated a fund-raising campaign to increase the size of the current fund. More information can be found at http://www.karstwaters. org/scholarship/wilsondonate.htm Articles, reports, and news of interest that relates to the mission and development of KWI are encouraged at any time. Welcome to The Conduit--Annette Su mmers Engel K A R S T W A T E R S I N S T I T U T E THE CONDUITPage 3 2010 Annual Awards BanquetThe 2010 KWI Karst Awards banquet took place on Saturday evening, March 13, 2010, at the Sheraton Baltimore City Center Hotel. In attendance were 35 Karst Waters Institute guests, Board members, and affiliates from around the world. The Karst Award recipient this year was Professor William R. Jeffery of the University of Maryland College Park.

THE CONDUIT KWI Happenings K A R S T W A T E R S I N S T I T U T E THE CONDUITPage 4 Board and Institute Members Me et in Baltimore, Maryland KWI met in Baltimore, Maryland, on March 13, 2010. The Board meeting was called to order, and there were four guests. Reports from the Education, Research, and Communications departments were submitted. The morning bounced between th e Board meeting and the Institute meeting in order to effectively discuss old and new business. The afternoon meeting was devoted to voting on agenda items. Several new policy statements passed, including that there can be foreign language translations of KWI publications deemed acceptable for research and/or educational purposes, and that no board member, staff member, or officer of KWI may provide testimony in name of Karst Waters Institute without Board authorization. KWI also voted to pursue joining the Amer ican Geological Institute (AGI). Several changes were made to the internal structure of KWI. New committees for Finance andBudget, Audit, Nominations, and Awards were appointed from the Board. Attendees continued to discuss a cohesive 5-year plan for four KWI-sponsored conferences and other educational and training activities, which is a deviation in the past when conferences were organized, more or less, one by one. This strategy will allo w KWI to seek funding opportunities for multiple years, rather than year by year. This exciting plan will provide various outlets for karst researchers, students, and enthusiasts to get involvedwith KWI in the future. KWI and the American Geological Institute As of late spring, KWI became a member society of AGI, an umbrella organization with other 47 member societies, including the National Speleological Society.One of AGIÂ’sroles relates to geoscienceeducati on, and it strives to increase public awareness of the importance of geological resources, natural hazards, and the health of the environment.More information about AGIÂ’sactivities can be found at http://www.agiweb.org/ Upcoming Karst Meetings2010 National Speleologi cal Society Convention August 2-6, 2010; Vermont, USA Early registration deadline has been extended to June 29, 2010 (save $20). 12th Multidisciplinary Conference on Sinkholes and the Engineering and Environmental Impacts of Karst January 10-14 2011; St. Louis, Missouri, USA. The goal of this conference is to share knowledge and experien ceamong disciplines by emphasizing scientific and technological a spects of karst that have practical appl ications, together with case histories of thos e applications. Since karst topography impacts grou nd and surface water resources, waste disposal and management, highways and other transportati on facilities, structural foundations and utilit ies and other infrastructure, civil, geotec hnical and environmental professionals should all attend this most relevant conference. Abstracts must be submitted by July 1, 2010.

Wilson Scholarship Fundraising Campaign Each year, KWI awards the William L. Wilson Scholarship to a worthy Master of Science graduate student, which comes with a one-time award of $1000. The awards are competitive, and are meant not only to offset ever-increasing costs of doing research, but also to stimulate the development of a new, en ergetic, motivated, and creative karst scientist. The award was established in Bill WilsonÂ’s memory and honors his dedication to karst science. For the next year, KWI has an ongoing fundraising campaign to increase the size of the current fund Information can be found on the KWI website if interested in making tax-deductable contributio ns-http://www.karstwaters.org/scholarship/wilsondonate.htm.
K A R S T W A T E R S I N S T I T U T E THE CONDUITPage 5 Feature: Where Are They Now? Research summaries from past William L. Wilson Scholarship recipientsCaving in Paradise: The 2005 William L. Wilson Scholarship in Karst Science -Text and figures submitted by Lindsay Walker CanmoreMuseum & GeoscienceCentre, Canmore, AB, Canada I received the William L. Wilson Scholarship in Karst Science in2005 to help fund my MasterÂ’s Thesis research on Abaco Island, Ba hamas. My work on Abaco had three main objectives: 1) to conduct a preliminary geological overview of the island, 2) to map the occurrence of caves and karst features and 3) to investigate the possibility of cone karst landforms. Upon completion of my thesis, I published three manuscripts wit h the help of my co-authors, each focusing on one of the above points. The references are listed below for your interest. Prior to this study, very little geological work had been conducted on Abaco. Our work showed that the geology of Abaco is similar to that of other Bahamian Islands and fits within the accepted Bahamian stratigraphy. Outcrops are dominantly composed of Pleistocene eolianitepackages separated by terra rosapaleosolswith some subtidaland beach faciespreserved in the younger packages. The eolian, beach, and sub tidalfaciesare deposited during sea level highstands, when the carbonate platform is flooded, while the paleosolsrecord sea level lowstands, when the platform is exposed. The Pleistocene rocks are sometimes overlain by Holocene eoliana nd beach facies. The Holocene rocks are not overlain by a paleosol, as there has been no lowstandsince their deposition. Karst features on Abaco include flank margin caves, karren, blue holes, pit caves, and banana holes. Flank margin caves, the most significant of these features, form as a result of mixing dissolution at the margin of the fresh-water lens. Because the margin of the lens is concordant with sea level, flank margin caves mark the position of sea level during their formation. HunterÂ’s Cave (Figs. 1 & 2) is an example of a flank margin cave. The inside walls show the original eolianbedding truncated by phreatic dissolutionalsurfaces (Fig. 2). Pseudokarstfeatures on Abaco include tafonicaves and cone-shaped hills that resemble tropical cone karst. Tafonicaves in the Bahamas are formed when the hard, outer calcretecrust of an eoliandune is removed, exposing the soft inner layers to erosion. The cone hills are the resultof the dissection of hummocky eolianiteridges by both karst and mechanical processes. This erosion results in talus slopes, which along with vegetative cover can mask the original asymmetrical profile of the dune (Fig. 3). The pseudokarst features are significant as they can of ten be mistaken for karstfeatures by the untrained observer. The tafonicaves, for example, can be confused with flank margin caves, leading to in correct estimates of past sea levels.Walker, L.N., 2006, The caves, karst, and geology of Abaco Island, Bahamas.

THE CONDUIT K A R S T W A T E R S I N S T I T U T E THE CONDUITPage 6 MoonmilkResearch: The 2007 William L. Wilson Scholarship in Karst Science Text submitted by Megan Denise Curry Waco, Texas I received the William L.Wilson Scholarship in 2007. During that time, I was at New Mexico Institute of Mining and Technology, in Socorro, New Mexico, doing my MS thesis research, Â“A geom icrobiologicaland geochemical approach to the biogenicityof moonmilkformation: Spider Cave and PahoehoeCave, NM; Thursday Morning Cave, CO; Thrush Cave and Cataract Cave, AK.Â” Moonmilkis a general term applied to white, pasty deposits that occur in a wide variety of cave environments across the world. More precisely itconsists of a two-phase (solid/liquid) speleothem that is a porous authigenicmicrocrystalline mineral aggregate with variable mineralogiesthat form within various lithologicalsubterranean cavities. Many secondary deposits within caves (speleothems) are known to be the resu lt of primarily physiochemical processes. However, moonmilk does not appear to be explainable via the same abioticmechanisms and does not have the same morphologies and textures as traditional speleothems (i.e., stalagmites a nd stalactites). Moonmilkdiffers from other speleothems in its high biomass content high porosity, high water content, variable mineralogy, and needle-fiber crystal morphology. Several explanations have been proposed concerning the origin of moonmilk, however, the body of work is sparse and th e origin still unclear. A microbial role is suggested by the presence of needle-fiber calcite, mineral encrustation around microbial filaments, and significant biofilm content. To explain its observed physical, chemical, and biological properties, we hypothesize that moonmilkis the product of a passive, microbially-mediated disaggregation of host rock and reprecipitationof carbonate from bedrock in a groundwater seepage-driven evaporative process. In order to test the degree to whichmoonmilkis the product of biological activity, this study distinguishes the biotic components and interactions from abioticones. All moonmilksfrom this study displayed a significant organic carbon presenceavailable for potential heterotrophic activity. Amongst the different study sites there were similar total microbial cell counts exhibiting a significant microbial presence. I n addition, in situ inoculation of samples into calcium salts me dia produced mineralization but not in controls. Thus, this resul t shows the potential for isolates to produce biologically-induced mineralization under appropriate conditions. Molecular results revealed that moonmilkisolates, from PahoehoeCave, were grouped with common soil bacteria taxaand were related to other bacteria from lava tube and freshwater microbial mats. Independent of depositional environment and climate, e.g. alpi neto desert, the moonmilksdisplayed micrometer-scale calcite needle-fiber morphology and significant biotic components such as filaments, filamentous mats, cellular bodies, and biofilm. Yet, the deposits displayed changes in macroscopic and microsc opic morphological and textural characteristics, and isotopic signatures associated with th e relative age and environmental influences. Macr oscopic textural and structural integrity is dependent on depositional environment. Cottonballsare peculiar moonmilk-like subaqueous calcite deposits that are also composed of microcrystalline needle-fiber aggregates and heavily entwined within a mass of microbialfilaments. The differences observed between the subaerialmoonmilkand cotton ballsmay be largely attributed to the changes in the depositional environment, namely in air or water. Stable isotop ic signatures among the moonmilkvaried and, thus, reflected a consortium of various environmental car bon sources and processesassociated with each site. Not all moonmilkis biologically active when collected. The presence of different crystal morphologies (i.e., stacked rhombohedra) in hydrologicallyinactive deposits suggests that potential diagenesismay have occurred. The highly distinctive appearance of moonmilkat spatial scales from macroscopic to microscopic potentially makes it a very valuable subsurface biosignature. Understanding this aspect is critical to future interpretationof any such materials in an extraterrestrial context. This research can aid the understanding of microbial roles in biomineralization, particularly of carbonates. Further, such material can serve as a biosignaturere presentative of a significant subsurface set of processes here on Earth of potential application to future missions for life detection in extraterrestrial subsurface sites.

K A R S T W A T E R S I N S T I T U T E THE CONDUITPage 7 Recent KWI Activities at International ConferencesInternational Conference: HypogeneSpeleogenesis & Karst Hydrogeology of Artesian Basins Chernivtsi, Ukraine, May 13-17, 2009 The International Conference "HypogeneSpeleogenesis & Karst Hydrogeology of Artesian Basins" was held in Chernivtsi, Ukraine, May 13-17, 2009. It was organized under auspices of the Union International of Speleology (UIS) and its Commission on Karst Hydrogeology and Speleogenesis, International GeoscienceProgram 513 "Global Study of Karst Aquifers and Water Resources" (UNESCO) and the International Year of Planet Earth (UNESCO-IUGS). The principal organizer of the Conference was the Ukrainian Institute of Speleology and Karstology(UISK). The co-organizers and sponsors of the Conference include: -Fed'kovichChernivtsyNational University, Ukraine -VernadskyTavricheskyNational University, Ukraine -Institute of Geological Sciences, National Academy of Science, Ukraine -National Cave and Karst Research Institute, USA -Karst Waters Institute, USA -Silesian University, Poland -Katowice Section of the Polish Geographic Society, Poland -Ukrainian Speleological Association The current surge in rec ognition of the broad occurrence and significance of hypogenespeleogenesis (i.e. spele ogenesis driven by groundwater and aggressiveness coming from depth), as well as of its marked specifics in comparison to better studied epigenic(hypergenic) karst (i.e. karst formed by groundwater coming from the overlying or immediately adjacent surfaces) has stimulated intense theoretical and regional studies on the topic worldwide. Timely excha nge of ideas and results of ongoing studies is particularly important during this period. The Conference, --Text and photographs submitted by Dr. Alexander Klimchouk Separated at birth?

THE CONDUIT K A R S T W A T E R S I N S T I T U T E THE CONDUITPage 8 therefore, aimed to provide such a possibility, and to overview the current developments and advances in the area. The specifi c reason for conducting this Conference in the Western Ukraine wasthe representativeness of the region and its caves for the evolving theory of hypogenespeleogenesis. The Conference venue was the historic main building of the Fed'kovichChernivtsiNational University and the Bukovina Hotel in Chernivtsi. Fifty three scientists and cave explorers have attended the Conf erence, representing 23 nations including: Australia, Austria, Brazil, Canada, France, Great Britain, Germany, Greece, Iraq, Israel, Italy, Mexico, Norway, Poland, Russia, Romania, Slovenia, Spain, Switzerland, Turk ey, Ukraine, and United States. During two days of scientific sessions (13 and 14 of May) thir ty-three papers were presented. The Conference has culminated with a panel discussion centered on the problem of definition and criteria of identification of hypogenespeleogenesis. The very stimulating and thoughts-provoking discussion have revealed many aspects still to be studied and clarified, as one could expect for the rapidly evolving area. It is quite evident, however, that the growing understanding of the nature, regularities, and th e broad occurrence of hypogenespeleogenesis signifies the ongoing change of the karst paradigm and is of a great importance for theoretical karstologyand geospeleology. This understanding is also crucial for our ability to adequately resolve problems related to the protection and management of karst groundwater resources, for karst sinkhole/subsidence hazard prediction and mitigation, as well as for prospecting and exploratio n of oil and gas resources and other economic deposits. During the following three days (May 15-17), field trips through the gypsum karst of the Wester n Ukrainewere taken. The trips served to illustrate scientific and practical aspects of hypogenespeleogenesis, karst hydrogeology of artesian basins, and engineering geology of covered karst. The trips were designed todemonstrate a spectrum of evolutionary types of karst and some of the outstanding gypsum caves present in the region, including Kristal'na, Yubileyna, Ozernaand Zoloushkacaves. The latter two are among the world longest caves, with their respective lengths of 128 and 92 km. Although the Conference participants have visited the area around OptymistychnaCave, the second longest cave in the world and the longest one in gypsum, it was not possible to visit this cave because the morphology of its entrance series is not suitable for quick visits b y large groups. The field trips also included a number of sites ofcultural importa nce. The Conference participants gratefully acknowledged the assistance of cavers from the speleological clubs of Ternopil, Chernivtsi, and Kishinev (Moldova) in arranging the visits to the caves that they explore and manage. For the Conference, the organizers published the proceedings volu me containing full texts of most papers and several books relevant to the topic (see references on pg 9), which were valu able contributions to the upcoming 15th International Congress o f Speleology (July-August 2009, Kerrville, USA). By the unanimous opinion of the participants, the Conference ha sbeen of a great success. It continued a topical series that started with the HypogeneSpeleogenesis Symposium held with in the GSA Meeting in Houston,USA, in October 2008, organized by the US National Cave and Karst Research Institute. In light of the rapid developments in the field, it seems desirable to have specific events on HypogeneSpel eogenesis regularly during the next several years. 2009 Â“HypogeneSpeleogenesisÂ”Conference par ticipants, ChetnivtsyUniversity, Ukraine.

ISBN 978-83-87431-94-5In this book geological the condit ions of speleogenesis in the Mi ocene gypsum in the Western Uk raine are characterized, particu larly the role of lithologicaland structural prerequisites in speleogenesis. The special attention is given to structural and textural unhomog eneitiesin the gypsum stratum and to their role in the formation of fractures. Fracture networks in the gypsum and the structure of the unique maze cave systems are examined in details. It is shown that speleo-initia ting fractures in the gypsum strata belong to the lithogeneticty pe and form largely independent multi-storey networks, with each storey being confined within a certain vertical structural/textural zone ( unit) of the stratum. This determines the multi-storey structure of the caves in the region. Two problems related to structural and text ural characteristics of the gypsum stratu m are discussed in details: the formation o fgiant dome structures by way of gypsum recrystallizat ionduring the synsedimentaryand early diagen esisstages, and the genesis of fractures. Speleogeneticrealization of the existing st ructural prerequisites occurred under conditions of a confined multi-storey artesian aquifer system due to an upward flow across the gypsum from the under-gypsum aquife r. The book may be of interest for karstologists, speleolog ists, engineering geologists, hydrogeologist, as we ll as for those who study lithologyand petr ography of evaporates.
