Publikováno v: Biogeosciences, Vol 18, Pp 3485-3504 (2021)

The West Antarctic Ice Sheet (WAIS) is one of the largest potential sources of future sea-level rise, with glaciers draining the WAIS thinning at an accelerating rate over the past 40 years. Due to complexities in calibrating palaeoceanographic proxi

Temporal variability in foraminiferal morphology and geochemistry at the West Antarctic Peninsula: a sediment trap study

Autor: A. Mikis, K. R. Hendry, J. Pike, D. N. Schmidt, K. M. Edgar, V. Peck, F. J. C. Peeters, M. J. Leng, M. P. Meredith, C. L. Todd, S. Stammerjohn, H. Ducklow

Publikováno v: Biogeosciences, Vol 16, Pp 3267-3282 (2019)

The West Antarctic Peninsula (WAP) exhibits strong spatial and temporal oceanographic variability, resulting in highly heterogeneous biological productivity. Calcifying organisms that live in the waters off the WAP respond to temporal and spatial var

Autor: D. A. Hodgson, K. Hogan, J. M. Smith, J. A. Smith, C.-D. Hillenbrand, A. G. C. Graham, P. Fretwell, C. Allen, V. Peck, J.-E. Arndt, B. Dorschel, C. Hübscher, A. M. Smith, R. Larter

Publikováno v: The Cryosphere, Vol 12, Pp 2383-2399 (2018)

The East Antarctic Ice Sheet discharges into the Weddell Sea via the Coats Land ice margin. We have used geophysical data to determine the changing ice-sheet configuration in this region through its last glacial advance and Holocene retreat and t

Physical habitat in conterminous US streams and rivers, Part 1: Geoclimatic controls and anthropogenic alteration

Autor: Philip R. Kaufmann, Robert M. Hughes, Steven G. Paulsen, David V. Peck, Curt W. Seeliger, Marc H. Weber, Richard M. Mitchell

Publikováno v: Ecological Indicators, Vol 141, Iss , Pp 109046- (2022)

Anthropogenic alteration of physical habitat structure in streams and rivers is increasingly recognized as a major cause of impairment worldwide. As part of their assessment of the status and trends in the condition of rivers and streams in the U.S.,

Physical habitat in conterminous US streams and Rivers, part 2: A quantitative assessment of habitat condition

Autor: Philip R. Kaufmann, Robert M. Hughes, Steven G. Paulsen, David V. Peck, Curt W. Seeliger, Tom Kincaid, Richard M. Mitchell

Publikováno v: Ecological Indicators, Vol 141, Iss , Pp 109047- (2022)

Rigorous assessments of the ecological condition of water resources and the effect of human activities on those waters require quantitative physical, chemical, and biological data. The U.S. Environmental Protection Agency’s river and stream surveys

Genus-level, trait-based multimetric diatom indices for assessing the ecological condition of rivers and streams across the conterminous United States

Autor: Luisa Riato, Ryan A. Hill, Alan T. Herlihy, David V. Peck, Philip R. Kaufmann, John L. Stoddard, Steven G. Paulsen

Publikováno v: Ecological Indicators, Vol 141, Iss , Pp 109131- (2022)

Taxonomic inconsistency in species-level identifications has constrained use of diatoms as biological indicators in aquatic assessments. We addressed this problem by developing diatom multimetric indices (MMIs) of ecological condition using genus-lev
