title: Collaborative Research: TransArctic Paleoclimate of the Eocene

description: This collaborative research effort sought to apply the stable isotope techniques pioneered by the principal investigators for Axel Heiberg terrestrial fossils across a Trans-Arctic trajectory of Eocene field sites. The principal investigators retrieved fossil materials from the Eastern High Arctic (Axel Heiberg and Ellesmere Island; 2008), the Western High Arctic (Banks Island; 2009), and near Anchorage, Alaska (2010). Fieldwork and the resulting analyses of sediments and plant/vertebrate fossils across these sites provided global quantification of Eocene northern high-latitude paleoclimate. In addition to the techniques pioneered for fossil wood, cellulose, resin, organic matter and carbonate, they applied two new chemical techniques involving phenylglucosazone derived from cellulose to imply the oxygen isotope composition of environmental water, and the use of lipid biomarkers known as glycerol dialkyl glycerol tetraethers (GDGTs) to infer soil temperature. They anticipated that their analyses will yield a quantification of organismal carbon-cycling, soil temperature, atmospheric relative humidity, environmental water source and inference of weather pattern, across a global Eocene Arctic transect. These analyses are specifically designed to exploit the exceptionally well-preserved terrestrial organic compounds of the mummified trees and litter layers within Arctic Eocene sediments.

title: Barrow Area Remote Sensing - Brw Be Land Cover

description: This dataset contains Barrow Area Remote Sensing - Brw Be Land Cover data. Cloud free Quickbird satellite imagery was used to develop the land cover maps in this study. The dataset is composed of four multispectral (2.4m) and one panchromatic (0.6m) band. The multispectral bands were fused with the panchromatic scene using a Principal Components sharpening method, which characteristically maintains spatial and spectral quality (Vijayaraj et al., 2006). Ten land cover types were chosen for the land cover classification. These included seven vegetated land cover types identified from cluster analysis of plot level species cover data from the International Tundra Experiment (ITEX) and resampled International Biological Program (IBP) plots, bare ground, ice/snow/urban areas, and water.

title: Leaf wax hydrogen isotope data, and modern precipitation isotope data, Lake E5, Alaska, 2014-2018

description: The Late-Quaternary climate of Beringia remains unresolved despite the region’s role in modulating glacial-interglacial climate and as the conduit for human dispersal into the Americas. We investigate Beringian temperature change using an ~32,000-year record of leaf wax hydrogen isotope ratios (δDwax) archived in lake sediments in Arctic Alaska. Temperatures were 2.9 °C colder during the Last Glacial Maximum (LGM; 21-25 thousand years before present, ka) than the pre-industrial era (PI; 2-0.1 ka). LGM temperatures were substantially warmer than in other parts of the Arctic, reflecting the greater continentality and altered atmospheric circulation which together contributed to weaker, rather than amplified, glacial cooling in the region. The transition to Holocene warmth was punctuated by abrupt events that are largely synchronous with events seen in Greenland ice cores but which also arise from local processes. Warming of 1.7 °C over the anthropogenic era has reversed a 5.5 °C decline through the Holocene, such that that recent warming in Arctic Alaska has not surpassed peak Holocene warmth. Our reconstruction, together with climate modeling experiments, indicates that Eastern Beringia responds more strongly to global climate forcings under modern-day, open-Bering Strait conditions.

title: Trust Network Relations-Water Stakeholders Analysis. S.Qanat.YZD.IRN. 2019.

description: Trust is referred to as the main adaptive governance factor. The trust ties in the network analysis questionnaire are the type and extent of individual trust relationships with each other. Participation ties are participations in the governance of the Qanat network. Each of the two trust and participation matrices was quantitatively analyzed based on network analysis indices using software UCINET 6.528. Finally, based on the Boolean combination, the trust and participation matrices were combined to determine the key stakeholders in the network governance of Sadrabad Qanat. In this research, social network theory and its principles have been used to analyze the structure of the pattern of relationships among different stakeholders.

title: Semi-structured interviews with Iñupiaq community elders, Wainwright, Alaska, 2013-2014

description: Semi-structured interviews with Community Elders regarding: 1) The environmental and social changes they have already observed in their lifetimes and their hopes and fears for the future in the context of incoming industrial development and the potential for more environmental and social changes to come (both positive and negative). 2) Whether or not they felt that their community was currently in the best position possible to both take advantage of the opportunities as well as face the challenges that such change could represent and whether they had any suggestions for improvements in terms of local decision-making processes, etc. 3) About the knowledge and practices they felt were most needed to be documented and communicated to outside decision-makers. Participants were also asked to identify some of the cultural values and traditional practices that they felt were critically important to pass on to the youth within their own Tribe. 4) Overall, what they felt was the most important thing that their community could do to embrace the changes to come while still maintaining the core values of their culture. Emphasis in these interviews were put on their perspectives as knowledgeable and respected elders, especially when it came to offering their critiques and suggestions about present conditions and future courses of action for their community. The structure of the interviews was relatively loose to allow the elders to freely share their recollections from the past and to generally speak about whatever they most preferred to discuss.

title: Doctoral Dissertation Improvement: Sociocultural Influences on Diet, Physical Activity, and Nutritional Status Among Older Adults in Anchorage, Alaska

description: This award supported research to examine the sociocultural factors that shape diet, physical activity practices, and nutritional status among an ethnically diverse sample of Alaskan older adults (adults aged 65+ years) living in Anchorage. This project (1) identified and evaluated the influence of sociocultural factors on dietary and physical activity patterns among urban Alaskan elders, and (2) identified relationships between the sociocultural environment, diet, physical activity, and nutritional status in this population. This 9-month long mixed-methods research study employed participant observation, semi-structured interviews, questionnaires, and anthropometric techniques. Fifteen interviews were conducted with seniors in Anchorage to identify the sociocultural factors that influence diet and physical activity practices. From these data, the investigator finalized the questionnaires which measures typical foods eaten (food frequency), engagement in physical activities, and the strength of sociocultural influences on these dietary and activity practices (a cultural survey). This questionnaire was orally administered by the researcher as a structured interview and anthropometric measurements (height, weight, and waist circumference) were taken with a convenience sample of 82 seniors in Anchorage. Anthropometric measurements were used to determine body mass index (BMI) and the prevalence of normal weight, overweight, and obesity. This research project will contribute to a deeper understanding of the social and cultural context of aging and health among urban Alaskan elders.

title: Education and community viability in Western Alaska, 2012-2015

description: DATA ARE NOT SUPPLIED HERE DUE TO SENSITIVITY SURROUNDING HUMAN SUBJECTS. PLEASE CONTACT DR. LOWE FOR MORE INFORMATION. A cross-section of youth and young adults across the Bering Sea region were interviewed on their post-secondary educational opportunities facilitated by the Community Development Quota (CDQ) program. The overarching project research question was: Do opportunities in post-secondary education for youth contribute to the viability of Bering Sea communities and way of life? "Viability"is defined by the degree to which a community can balance in- and out-migration, sustain a context of livelihood diversification, and create bridges to resources external to the community. To answer the research question, the investigators therefore also asked: Are there differences between contributions of college degree earners and those of vocational training graduates? What is the effect of post-secondary education on rural community out-migration for youth in Alaska? What is the effect of post-secondary education on occupation selection among rural Alaska youth? What kinds of educational opportunities contribute to bridging youth with resources external to coastal communities? Are there academic, sociocultural, or economic constraints preventing students from completing their studies or training? Hypotheses tested included the following: 1) More educational scholarships are awarded than vocational training grants. 2) More women are applying for post-secondary awards. 3) Completion of post-secondary education is correlated with outmigration. 4) Participation in educational "bridging" programs contribute to completion of education or training. 5) The majority of respondents who did not complete their studies dropped out after one year. 6) The average time to completion of studies is much longer than the traditional four years. 7) Having a social support network contributes to completion of studies. 8) Lack of adequate academic preparation contributes to non-completion of studies. 9) Financial hardship/poverty contributes to non-completion of studies. 10) Most people leave Western Alaska to find employment. Data sets included: 1) Western Alaska regional profile summaries of U.S. Census and State of Alaska data on: demographics, employment, development, subsistence economy data, educational statistics, and subsistence harvest data. 2) Ethnographic fieldnotes; 3) Focus group interview transcripts from 31 students interviewed at the University of Alaska and Alaska Career Academy; 5) An SPSS data file of 351 survey responses for survey on Alaska rural youth scholarship outcomes.

title: Fisheries Privatization, Sociocultural Transitions, and Well-Being in Kodiak, Alaska

description: Scholars and fishermen alike view the privatization of fishing rights as a fundamental driver of change in fishing livelihoods and communities. Expanding upon ethnographic research conducted in rural fishing communities in the Gulf of Alaska, this project explores the social and cultural shifts linked to the privatization of fishing rights in the diverse fishing community of Kodiak, Alaska. This study has three primary objectives: 1) to understand how the privatization of fishing rights has been experienced across diverse human groups that participate in fishery systems, 2) to explore the relative importance and magnitude of the impacts of fisheries privatization compared with other ecological, economic, and technological drivers of change, and 3) to assess the relationship between the social and cultural shifts linked to fishery privatization and individual and community well-being. This ethnographic study, employing mixed methods of interviews, surveys, participant observation and archival research, will provide rich qualitative and systematic quantitative data to assess how regulatory and related changes affect the social and cultural dimensions of fishery systems and fishing communities. The research framework joins scholarship in political ecology, social-ecological systems, and the anthropology of fishing communities to provide key analytical insights into the relationship between the enclosure of resources and changing nature-society relationships. The research findings will have broad applicability to understanding transitions in fishing communities in the Gulf of Alaska, Bering Sea, and throughout the Circumpolar North. This study also informs resource policy development. As fishery economists, managers, environmental groups, and popular media sources increasingly advocate for the widespread privatization of marine resources, the social and cultural implications of these transitions need to be explored and documented. The results of this study will have practical application in understanding how to develop new adaptive models of institutional and ecological management that will provide for the resilience of fishing-dependent communities. Shifts to ecosystem-based marine governance call for increased attention to the ways in which individual and community health and well-being and general concerns of social justice are addressed in policy development. The research will provide insights on how the diversity of livelihoods and values can be better accounted for in resource management policy in the arctic, sub-arctic and beyond.
