Publikováno v: Earth Surface Dynamics, Vol 9, Pp 1363-1380 (2021)

Outlet glaciers that flow through the Transantarctic Mountains (TAM) experienced changes in ice thickness greater than other coastal regions of Antarctica during glacial maxima. As a result, ice-free areas that are currently exposed may have been cov

Previous studies have established links between biodiversity and soil geochemistry in the McMurdo Dry Valleys, Antarctica, where environmental gradients are important determinants of soil biodiversity. However, these gradients are not well establishe

Stream biogeochemical and suspended sediment responses to permafrost degradation in stream banks in Taylor Valley, Antarctica

Autor: M. N. Gooseff, D. Van Horn, Z. Sudman, D. M. McKnight, K. A. Welch, W. B. Lyons

Publikováno v: Biogeosciences, Vol 13, Iss 6, Pp 1723-1732 (2016)

Stream channels in the McMurdo Dry Valleys are characteristically wide, incised, and stable. At typical flows, streams occupy a fraction of the oversized channels, providing habitat for algal mats. In January 2012, we discovered substantial channel e

Silicate weathering and CO2 consumption within agricultural landscapes, the Ohio-Tennessee River Basin, USA

Autor: K. A. Welch, S. A. Welch, M. J. Shipitalo, A. E. Carey, W. B. Lyons, S. K. Fortner

Publikováno v: Biogeosciences, Vol 9, Iss 3, Pp 941-955 (2012)

Myriad studies have shown the extent of human alteration to global biogeochemical cycles. Yet, there is only a limited understanding of the influence that humans have over silicate weathering fluxes; fluxes that have regulated atmospheric carbon diox
