Autor: M. Riedel, K. M. M. Rohr, G. D. Spence, D. Kelley, J. Delaney, L. Lapham, J. W. Pohlman, R. D. Hyndman, E. C. Willoughby
Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 21, Iss 8, Pp n/a-n/a (2020)
Abstract Geophysical and geochemical data indicate there is abundant fluid expulsion in the Nootka fault zone (NFZ) between the Juan de Fuca and Explorer plates and the Nootka continental slope. Here we combine observations from >20 years of investig

The Effects of Engineered Aeration on Atmospheric Methane Flux From a Chesapeake Bay Tidal Tributary
Autor: Laura L. Lapham, Edward A. Hobbs, Jeremy M. Testa, Andrew Heyes, Melinda K. Forsyth, Casey Hodgkins, Curtis Szewczyk, Lora A. Harris
Publikováno v: Frontiers in Environmental Science, Vol 10 (2022)
Engineered aeration is one solution for increasing oxygen concentrations in highly eutrophic estuaries that undergo seasonal hypoxia. Although there are various designs for engineered aeration, all approaches involve either destratification of the wa

Hidden Processes During Seasonal Isolation of a High-Altitude Watershed
Autor: Jessica Z. Buser-Young, Laura L. Lapham, Andrew R. Thurber, Kenneth H. Williams, Frederick S. Colwell
Publikováno v: Frontiers in Earth Science, Vol 9 (2021)
Biogeochemical processes capable of altering global carbon systems occur frequently in Earth’s Critical Zone–the area spanning from vegetation canopy to saturated bedrock–yet many of these phenomena are difficult to detect. Observation of these

Microbial Greenhouse Gas Dynamics Associated With Warming Coastal Permafrost, Western Canadian Arctic
Autor: Laura L. Lapham, Scott R. Dallimore, Cédric Magen, Lillian C. Henderson, Leanne C. Powers, Michael Gonsior, Brittany Clark, Michelle Côté, Paul Fraser, Beth N. Orcutt
Publikováno v: Frontiers in Earth Science, Vol 8 (2020)
Permafrost sediments contain one of the largest reservoirs of organic carbon on Earth that is relatively stable when it remains frozen. As air temperatures increase, the shallow permafrost thaws which allows this organic matter to be converted into p

Publikováno v: Elementa: Science of the Anthropocene, Vol 5 (2017)
Weathered crude oil sank to the seafloor following the 'Deepwater Horizon' disaster in 2010, removing this oil from further physical and photo-chemical degradation processes and leaving benthic processes as the mechanisms for altering and remediating
