Lesleigh Anderson
Dr. Lesleigh Anderson is a Research Geologist who uses sedimentology, geochemistry, and remote sensing tools in freshwater systems (e.g., lakes, wetlands, and permafrost) in support of water resource management, including salt lakes and natural hazards. Dr. Anderson manages the Quaternary Research Facility for sediment core processing and analyses.
Main study areas are in the North America cordilleran west, from Alaska to the southern Rockies. Research focuses on the development of water isotope tracers and sedimentary records to investigate hydrologic change across space and through time to better understand implications for local to regional water availability, ecosystem transformations, and geologic hazards.

Isotopes in North American Rocky Mountain snowpack 1993–2014 Isotopes in North American Rocky Mountain snowpack 1993–2014
We present ∼1300 new isotopic measurements (δ18O and δ2H) from a network of snowpack sites in the Rocky Mountains that have been sampled since 1993. The network includes 177 locations where depth-integrated snow samples are collected each spring near peak accumulation. At 57 of these locations snowpack samples were obtained for 10–21 years and their isotopic measurements provide...

A multi-proxy record of hydroclimate, vegetation, fire, and post-settlement impacts for a subalpine plateau, Central Rocky Mountains U.S.A A multi-proxy record of hydroclimate, vegetation, fire, and post-settlement impacts for a subalpine plateau, Central Rocky Mountains U.S.A
Apparent changes in vegetation distribution, fire, and other disturbance regimes throughout western North America have prompted investigations of the relative importance of human activities and climate change as potential causal mechanisms. Assessing the effects of Euro-American settlement is difficult because climate changes occur on multi-decadal to centennial time scales and require...

Ocean-atmosphere forcing of centennial hydroclimatic variability in the Pacific Northwest Ocean-atmosphere forcing of centennial hydroclimatic variability in the Pacific Northwest
Reconstructing centennial timescale hydroclimate variability during the late Holocene is critically important for understanding large-scale patterns of drought and their relationship with climate dynamics. We present sediment oxygen isotope records spanning the last two millennia from 10 lakes, as well as climate model simulations, indicating that the Little Ice Age was dry relative to...

Controls on recent Alaskan lake changes identified from water isotopes and remote sensing Controls on recent Alaskan lake changes identified from water isotopes and remote sensing
High-latitude lakes are important for terrestrial carbon dynamics and waterfowl habitat driving a need to better understand controls on lake area changes. To identify the existence and cause of recent lake area changes in the Yukon Flats, a region of discontinuous permafrost in north central Alaska, we evaluate remotely sensed imagery with lake water isotope compositions and...

Rocky Mountain hydroclimate: Holocene variability and the role of insolation, ENSO, and the North American Monsoon Rocky Mountain hydroclimate: Holocene variability and the role of insolation, ENSO, and the North American Monsoon
Over the period of instrumental records, precipitation maximum in the headwaters of the Colorado Rocky Mountains has been dominated by winter snow, with a substantial degree of interannual variability linked to Pacific ocean–atmosphere dynamics. High-elevation snowpack is an important water storage that is carefully observed in order to meet increasing water demands in the greater semi...

Enhanced Late Holocene ENSO/PDO expression along the margins of the eastern North Pacific Enhanced Late Holocene ENSO/PDO expression along the margins of the eastern North Pacific
Pacific climate is known to have varied during the Holocene, but spatial patterns remain poorly defined. This paper compiles terrestrial and marine proxy data from sites along the northeastern Pacific margins and proposes that they indicate 1) suppressed ENSO conditions during the middle Holocene between ∼8000 and 4000 cal BP with a North Pacific that generally resembled a La Niña-like...
