  • Wind-modulated groundwater discharge along a microtidal Arctic coastline

    Open AccessJulia Guimond, Cansu Demir et al.ARTICLEEnvironmental Research Letters2023

    Groundwater discharge transports dissolved constituents to the ocean, affecting coastal carbon budgets and water quality. However, the magnitude and mechanisms of groundwater exchange along rapidly transitioning Arctic coastlines are largely unknown due to limited observations. Here, using first-of-its-kind coastal Arctic groundwater timeseries data, we evaluate the magnitude and drivers of groundwater discharge to Alaska’s Beaufort Sea coast. Da…

  • Watershed slope as a predictor of fluvial dissolved organic matter and nitrate concentrations across geographical space and catchment size in the Arctic

    Open AccessCraig T Connolly, M S Khosh et al.ARTICLEEnvironmental Research Letters2018

    Understanding linkages between river chemistry and biological production in arctic coastal waters requires improved estimates of riverine nutrient export. Here we present the results of a synthesis effort focusing on relationships between watershed slope and seasonal concentrations of river-borne dissolved organic carbon (DOC), dissolved organic nitrogen (DON), and nitrate ( ${{{\rm{NO}}}_{3}}^{-}$ ) around the pan-Arctic. Strong negative relatio…

  • Multi-decadal increases in dissolved organic carbon and alkalinity flux from the Mackenzie drainage basin to the Arctic Ocean

    Open AccessSuzanne E Tank, Robert G Striegl et al.ARTICLEEnvironmental Research Letters2016

    Riverine exports of organic and inorganic carbon (OC, IC) to oceans are intricately linked to processes occurring on land. Across high latitudes, thawing permafrost, alteration of hydrologic flow paths, and changes in vegetation may all affect this flux, with subsequent implications for regional and global carbon (C) budgets. Using a unique, multi-decadal dataset of continuous discharge coupled with water chemistry measurements for the Mackenzie …

  • Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire

    Open AccessBenjamin W Abbott, Jeremy B Jones et al.ARTICLEEnvironmental Research Letters2016

    As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased production of Arctic and boreal biomass; however, the lack of robust estimates of net carbon balance increases the risk of further overshooting international emissions targets. Precise empirical or model-based assessments of t…

  • Coordination and Sustainability of River Observing Activities in the Arctic

    Open AccessJ W McClelland, Suzanne E Tank et al.ARTICLEARCTIC2015

    To understand and respond to changes in the world’s northern regions, we need a coordinated system of long-term Arctic observations. River networks naturally integrate across landscapes and link the terrestrial and ocean domains. Changes in river discharge reflect changes in the terrestrial water balance, whereas changes in water chemistry are linked to changes in biogeochemical processes and water flow paths. Sustained measurements of river wate…

  • Weight Loss and Self-Regulatory Eating Efficacy in Older Adults

    Open AccessW Jack Rejeski, Shannon L Mihalko et al.ARTICLEThe Journals of Gerontology…2011Cited by: 1References: 2

    These results illustrate that WL + PA can be effective in improving older adults' self-efficacy for the self-regulation of eating behavior and that these changes are prospectively related to the amount of weight loss. Further research is warranted on an expanded concept of self-efficacy as well as controlled experimental studies on eating behavior in older adults

  • Increasing River Discharge to the Arctic Ocean

    Open AccessBruce J Peterson, R M Holmes et al.ARTICLEScience2002

    Synthesis of river-monitoring data reveals that the average annual discharge of fresh water from the six largest Eurasian rivers to the Arctic Ocean increased by 7% from 1936 to 1999. The average annual rate of increase was 2.0 ± 0.7 cubic kilometers per year. Consequently, average annual discharge from the six rivers is now about 128 cubic kilometers per year greater than it was when routine measurements of discharge began. Discharge was correla…

  • Fruit and vegetable consumption and prevention of cancer

    Marci K Campbell, W Demark-Wahnefried et al.ARTICLEAmerican Journal of Public Health1999Cited by: 21References: 32

    OBJECTIVES: This study assessed the effects of the Black Churches United for Better Health project on increasing fruit and vegetable consumption among rural African American church members in North Carolina. METHODS: Ten counties comprising 50 churches were pair matched and randomly assigned to either intervention or delayed intervention (no program until after the follow-up survey) conditions. A multicomponent intervention was conducted over app…
