Since the late 1950\u0027s, human activity in the MDV has become commonplace in summer, putting pressure on the region\u0027s fragile ecosystems through camp construction and inhabitation, cross-valley transport on foot and via vehicles, and scientific research that involves sampling and deployment of instruments. Historical photographs, put alongside information from written documentation, offer an invaluable record of the changing patterns of human activity in the MDV. Photographic images often show the physical extent of field camps and research sites, the activities that were taking place, and the environmental protection measures that were being followed. Historical photographs of the MDV, however, are scattered in different places around the world, often in private collections, and there is a real danger that many of these photos may be lost, along with the information they contain. This project will collect and digitize historical photographs of sites of human activity in the MDV from archives and private collections in the United States, New Zealand, and organize them both chronologically and spatially in a GIS database. Sites of past human activities will be re-photographed to provide comparisons with the present, and re-photography will assist in providing spatial data for historical photographs without obvious location information. The results of this analysis will support effective environmental management into the future. The digital photo archive will be openly available through the McMurdo Dry Valleys Long Term Ecological Research (MCM LTER) website (www.mcmlter.org), where it can be used by scientists, environmental managers, and others interested in the region. \u003cbr/\u003e\u003cbr/\u003eThe central question of this project can be reformulated as a hypothesis: Despite an overall increase in human activities in the MDV, the spatial range of these activities has become more confined over time as a result of an increased awareness of ecosystem fragility and efforts to manage the region. To address this hypothesis, the project will define the spatial distribution and temporal frequency of human activity in the MDV. Photographs and reports will be collected from archives with polar collections such as the National Archives of New Zealand in Wellington and Christchurch and the Byrd Polar Research Center in Ohio. Private photograph collections will be accessed through personal connections, social media, advertisements in periodicals such as The Polar Times, and other means. Re-photography in the field will follow established techniques and will create benchmarks for future research projects. The spatial data will be stored in an ArcGIS database for analysis and quantification of the human footprint over time in the MDV. The improved understanding of changing patterns of human activity in the MDV provided by this historical photo archive will provide three major contributions: 1) a fundamentally important historic accounting of human activity to support current environmental management of the MDV; 2) defining the location and type of human activity will be of immediate benefit in two important ways: a) places to avoid for scientists interested in sampling pristine landscapes, and, b) targets of opportunity for scientists investigating the long-term environmental legacy of human activity; and 3) this research will make an innovative contribution to knowledge of the environmental history of the MDV.", "east": 163.9, "geometry": "POINT(162.05 -77.58)", "instruments": "NOT APPLICABLE \u003e NOT APPLICABLE \u003e NOT APPLICABLE", "is_usap_dc": true, "keywords": "CONTAMINANT LEVELS/SPILLS; Antarctica; NOT APPLICABLE; USAP-DC", "locations": "Antarctica", "north": -77.1, "nsf_funding_programs": "Antarctic Integrated System Science", "paleo_time": null, "persons": "Fountain, Andrew; Howkins, Adrian", "platforms": "OTHER \u003e NOT APPLICABLE \u003e NOT APPLICABLE", "repo": "EDI", "repositories": "EDI", "science_programs": null, "south": -78.06, "title": "Collaborative Research: Assessing Changing Patterns of Human Activity in the McMurdo Dry Valleys using Digital Photo Archives", "uid": "p0010066", "west": 160.2}, {"awards": "0943935 Isbell, John; 0943934 Taylor, Edith", "bounds_geometry": null, "dataset_titles": "Portal to search geologic sample collections, Polar Rock Repository, Byrd Polar Research Center, The Ohio State University; Portal to search paleobotanical collections, Biodiversity Institute, University of Kansas", "datasets": [{"dataset_uid": "002567", "doi": "", "keywords": null, "people": null, "repository": "PI website", "science_program": null, "title": "Portal to search paleobotanical collections, Biodiversity Institute, University of Kansas", "url": "http://biodiversity.ku.edu/paleobotany/collections/collections-search"}, {"dataset_uid": "001402", "doi": "", "keywords": null, "people": null, "repository": "PI website", "science_program": null, "title": "Portal to search paleobotanical collections, Biodiversity Institute, University of Kansas", "url": "http://biodiversity.ku.edu/paleobotany/collections/collections-search"}, {"dataset_uid": "001377", "doi": "", "keywords": null, "people": null, "repository": "PRR", "science_program": null, "title": "Portal to search geologic sample collections, Polar Rock Repository, Byrd Polar Research Center, The Ohio State University", "url": "http://research.bpcrc.osu.edu/rr/"}], "date_created": "Tue, 23 Sep 2014 00:00:00 GMT", "description": "Intellectual Merit:\u003cbr/\u003eThe focus of this proposal is to collect fossil plants and palynomorphs from Permian-Triassic (P-T) rocks of the central Transantarctic Mountains (CTM), together with detailed data on sedimentologic and paleoecologic depositional environments. Fossil plants are important climate proxies that offer a unique window into the past, and the CTM fossils are an important source of data on the ways that plants responded to a strongly seasonal, polar light regime during a time of global change. The proposed project uses paleobotanical expertise, integrated with detailed sedimentology and stratigraphy, to reconstruct Permian-Triassic plant communities and their paleoenvironments. This interdisciplinary approach could uncover details of Antarctica?s complex late Paleozoic and Mesozoic environmental and climatic history which included: 1) deglaciation, 2) development and evolution of a post-glacial landscape and biota, 3) environmental and biotic change associated with the end-Permian mass extinction, 4) environmental recovery in the earliest Triassic, 5) strong, possible runaway Triassic greenhouse, and 6) widespread orogenesis and development of a foreland basin system. The PIs will collect compression floras both quantitatively and qualitatively to obtain biodiversity and abundance data. Since silicified wood is also present, the PIs will analyze tree rings and growth in a warm, high-latitude environment for which there is no modern analogue. Fossil plants from the CTM can provide biological and environmental information to: 1) interpret paleoclimate when Gondwana moved from icehouse to greenhouse conditions; 2) trace floral evolution across the P-T boundary; 3) reconstruct Antarctic plant life; 4) further understanding of plant adaptations to high latitudes. The Intellectual Merit of the research includes: 1) tracing floral evolution after the retreat of glaciers; 2) examining floral composition and diversity across the PTB; and 3) obtaining data on the recovery of these ecosystems in the Early Triassic, as well as changes in floral cover and diversity in the Early-Middle Triassic.

To accomplish this goal the PIs will develop a detailed geochronology and analyze Hf- and O-isotopes of detrital zircons in sandstones of the Devonian Taylor Group and the Permian-Triassic Victoria Group. These data will allow them to better determine provenance and basin fill, and to understand the nature of the now ice covered source regions in East and West Antarctica. The PIs will document possible unexposed/unknown crustal terrains in West Antarctica, investigate sub-glacial terrains of East Antarctica that were exposed to erosion during Devonian to Triassic time, and determine the evolving provenance and tectonic history of the Devonian to Triassic Gondwana basins in the central Transantarctic Mountains. Detrital zircon data will be interpreted in the context of fluvial dispersal/drainage patterns, sandstone petrology, and sequence stratigraphy. This interpretation will identify source terrains and evolving sediment provenances. Paleocurrent analysis and sequence stratigraphy will determine the timing and nature of changing tectonic conditions associated with development of the depositional basins and document the tectonic history of the Antarctic sector of Gondwana. Results from this study will answer questions about the Panthalassan margin of Gondwana, the Antarctic craton, and the Beacon depositional basin and their respective roles in global tectonics and the geologic and biotic history of Antarctica. The Beacon basin and adjacent uplands played an important role in the development and demise of Gondwanan glaciation through modification of polar climates, development of peat-forming mires, colonization of the landscape by plants, and were a migration route for Mesozoic vertebrates into Antarctica. \u003cbr/\u003e\u003cbr/\u003eBroader impacts: \u003cbr/\u003eThis proposal includes support for two graduate students who will participate in the fieldwork, and also support for other students to participate in laboratory studies.

The purpose of the project is to assess the application of classified imagery to the study of the magnitude and rate of change of glacier extent and lake area as an indicator of climate change. Because the rate of change of both glacier extent and lake area is small compared to the resolution of unclassified imagery, the increased resolution of classified imagery is clearly needed. Access to classified imagery with 1 meter or better resolution will provide a baseline measurement against which future changes can be compared. Maximum use will be made of archived imagery but if necessary, one request will be made for new imagery to supplement the existing archive.
