Highlighting the Need and Potential for Use of Interdisciplinary Science in Adaptive Environmental Management: The Case of Endangered Upland Swamps in the Blue Mountains,NSW, Australia

The Blue Mountains region of New South Wales, including the World Heritage listed Blue Mountains National Park, is arguably one of Australia's most highly valued and iconic wilderness areas. Common to this region are upland swamps (formally ‘temperate highland peat swamps on sandstone’), which play a vital hydrological role at the headwaters of the river catchments, as well as providing the habitat for an array of flora and fauna species. This paper involves an interdisciplinary examination into the need and potential for adaptive management in the Blue Mountains. It uses geomorphic (physical) knowledge of swamp condition and social data about the volunteers who rehabilitate them. Research involved using the River Styles river condition framework across 47 swamps and questionnaires and interviews with local rehabilitation volunteers. It is proposed that there is a need and a potential to combine geomorphic understanding with further engagement of community volunteers in order to enable an interdisciplinary approach to adaptive management. Such an approach could result in the effective environmental management of upland swamps in the Blue Mountains.     

Patriot Graves: American national identity and the Civil War dead

The Civil War was America’s defining conflict, the war that made the nation and the fulcrum for the development of American national identity in the later nineteenth and early twentieth centuries. Yet the role that the Civil War dead played in this process has only begun to be explored. Although the monuments raised to honor the dead, along with the battlefields on which they fought, attract considerable interest, the cemeteries constructed to inter them have been integrated into the landscape – literal and figurative – of the American nation so fully that the need they answered, the manner of their development, the form they took, and their longer‐term symbolic message has been relatively neglected. Yet the Civil War dead were a crucial – indeed, the crucial – component in the construction of American national identity. Although scholars interpret American attitudes toward the Civil War dead within the context of the mourning rituals of the antebellum era, the war required, and produced, a different approach to death, for which antebellum precedent had ill‐prepared Americans. Removed from its antebellum religious and societal framework, death in the Civil War acquired a new and more potent national meaning that not only validated American nationalism through warfare, but anticipated the response to fallen soldiers in future European conflicts.     

Iron precipitation in a natural CO2 reservoir: Jurassic Navajo Sandstone in the northern San Rafael Swell,UT, USA

Diagenetic iron (oxyhydr)oxide minerals are common precipitates expected in CO₂ reservoirs, and these minerals record fluid flow for application to carbon capture and sequestration (CSS). Multiple mineralogy and spectroscopy analyses on a pore to meter scale characterize a well‐exposed, lithologically controlled, iron (oxyhydr)oxides reaction front in the Jurassic Navajo Sandstone. Dolomite is the most prevalent cement (up to 23 area%), followed by only several percent or less of iron (oxyhydr)oxides, kaolinite, illite, and gypsum cements. Bulk geochemistry based on diagenetic mineralogies in the reaction front is compared with the water chemistry from nearby modern spring effluent emanating from the Navajo Sandstone to conclude that similar fluids (i.e., CO₂‐charged, saline waters containing hydrocarbons) are responsible for the precipitation. A second comparison of bulk geochemistry and diagenetic mineralogies of the reaction front with data from other abundant Navajo Sandstone concretions in the Spencer Flat region (in south central Utah) shows that reservoir fluids likely vary spatially and temporally in the porous and permeable Navajo Sandstone. CO₂ injection into porous and permeable, quartz arenite, saline aquifers will likely result in minor clay and abundant dolomite precipitation that will significantly decrease porosity.     

Placing Sanctuaries in Their Socio‐Political Landscapes: A Diachronic Approach to the Late Iron Age Communities in South‐East Iberia (Fourth–Second Centuries BC)

This paper explores the relationship between the historical dynamics and the transformations observed in pre‐Roman cult places in eastern Iberia between the fourth and second centuries BC. These are analysed through a case study: the sanctuary of La Luz (Murcia), located in the Segura Valley, in south‐east Iberia. Three main religious changes are discussed from this perspective: the development of the sanctuary in the fourth century BC, the changes observed in its archaeological record in the third century BC, and finally its destruction in the second century BC. These offer a diachronic view of the transformations, and illustrate the different levels at which they were expressed, from the archaeological record to the landscape. The work aims to provide a different perspective from previous studies in this area and a new view of the cult places in south‐east Iberia within their socio‐political landscape and the Mediterranean historical context.     

CHARACTERIZING THE SEDIMENTARY HISTORY OF CAVE DEPOSITS,USING ARCHAEOMAGNETISM AND ROCK MAGNETISM,ATAPUERCA (NORTHERN SPAIN)

We use a combination of rock magnetism (anisotropy of magnetic susceptibility, AMS) and magnetic polarity to characterize cave deposits and as a proxy for sedimentary fabric. In three localities at the Atapuerca archaeological site (Galeria, Gran Dolina and Sala de los Cíclopes), magnetic foliation (K_max/K_int) is always greater than lineation (K_int/K_min), consistent with a primary, depositional, sedimentary fabric. Our results, although preliminary, reveal a higher degree of anisotropy in autochtonous deposits compared to allochthonous deposits, possibly indicative of a higher hydrodynamic regime in the former. At two localities the magnetic lineation (K_max) defines a cluster, which is thought to be antipodal to the palaeocurrent direction. Hence we are able to retrieve palaeoflow directions in deposits that otherwise lack any other sedimentary structure. We conclude that AMS is a powerful tool for determining the hydrodynamic character of depositional environments in cave sediments at the Atapuerca archaeological site. A better understanding of the depositional environment and how sedimentation occurred allows reconstruction of the karst evolution and ultimately a better definition of human interaction with the environment.
