Spatiotemporal transformation of dissolved organic matter along an alpine stream flow path on the Qinghai–Tibet Plateau: importance of source and permafrost degradation

Autor: Y. Wang, R. G. M. Spencer, D. C. Podgorski, A. M. Kellerman, H. Rashid, P. Zito, W. Xiao, D. Wei, Y. Yang, Y. Xu

Publikováno v: Biogeosciences, Vol 15, Pp 6637-6648 (2018)

The Qinghai–Tibet Plateau (QTP) accounts for approximately 70 % of global alpine permafrost and is an area sensitive to climate change. The thawing and mobilization of ice-rich and organic-carbon-rich permafrost impact hydrologic conditions an

Glacial meltwater drains into proglacial rivers where it interacts with the surrounding landscape, collecting microbial cells as it travels downstream. Characterizing the composition of the resulting microbial assemblages in transport can inform us a

Seasonal Changes in Dissolved Organic Matter Composition in a Patagonian Fjord Affected by Glacier Melt Inputs

Autor: Matthew G. Marshall, Anne M. Kellerman, Jemma L. Wadham, Jon R. Hawkings, Giovanni Daneri, Rodrigo Torres, Helena V. Pryer, Alexander Beaton, Hong Chin Ng, Alejandra Urra, Laura F. Robinson, Robert G. M. Spencer

Publikováno v: Frontiers in Marine Science, Vol 8 (2021)

Biogeochemical processes in fjords are likely affected by changes in surrounding glacier cover but very little is known about how meltwater directly influences dissolved organic matter (DOM) in fjords. Moreover, the data available are restricted to a

The Effects of Glacial Cover on Riverine Silicon Isotope Compositions in Chilean Patagonia

Autor: Helena V. Pryer, Jade E. Hatton, Jemma L. Wadham, Jon R. Hawkings, Laura F. Robinson, Anne M. Kellerman, Matthew G. Marshall, Alejandra Urra, Anna Covey, Giovanni Daneri, Vreni Häussermann, Katharine R. Hendry

Publikováno v: Frontiers in Earth Science, Vol 8 (2020)

Proglacial rivers have been shown to have distinctive silicon (Si) isotope compositions, providing new insights into the mechanisms controlling Si cycling in the subglacial environment and suggesting terrestrial Si isotope exports may have varied bet

A Tropical Cocktail of Organic Matter Sources: Variability in Supraglacial and Glacier Outflow Dissolved Organic Matter Composition and Age Across the Ecuadorian Andes

The biogeochemistry of rapidly retreating Andean glaciers is poorly understood, and Ecuadorian glacier dissolved organic matter (DOM) composition is unknown. This study examined molecular composition and carbon isotopes of DOM from supraglacial and o

Spatiotemporal response of dissolved organic matter diversity to natural and anthropogenic forces along the whole mainstream of the Yangtze River

Autor: Shuaidong Li, Lize Meng, Chu Zhao, Yu Gu, Robert G.M. Spencer, Xosé Antón Álvarez–Salgado, Anne M. Kellerman, Amy M. McKenna, Tao Huang, Hao Yang, Changchun Huang

12 pages, 9 figures
The Yangtze River, the largest river in Asia, plays a crucial role in linking continental and oceanic ecosystems. However, the impact of natural and anthropogenic disturbances on composition and transformation of dissolved or
