John P. Smol,Alexander P. Wolfe,H. John B. Birks,Marianne S. V. Douglas,Vivienne J. Jones,Atte Korhola,Reinhard Pienitz,Kathleen M. Rühland,Sanna Sorvari,Dermot Antoniades,Stephen J. Brooks,Marie-Andrée Fallu,Michael Hughes,Bronwyn E. Keatley,Tamsin E. Laing,Neal Michelutti,Larisa Nazarova,Marjut Nyman,Andrew M. Paterson,Bianca B.

TL;DR: Fifty-five paleolimnological records from lakes in the circumpolar Arctic reveal widespread species changes and ecological reorganizations in algae and invertebrate communities since approximately anno Domini 1850, indicating that the opportunity to study arctic ecosystems unaffected by human influences may have disappeared.
Journal ArticleDOI
Do spectrally inferred determinations of chlorophyll a reflect trends in lake trophic status
Neal Michelutti,Jules M. Blais,Brian F. Cumming,Andrew M. Paterson,Kathleen M. Rühland,Alexander P. Wolfe,John P. Smol +6 more
TL;DR: In this paper, the authors evaluate how well visible reflectance spectroscopy (VRS) determinations track past trends in aquatic primary production using sediment cores from several lake systems with well-known trophic histories.
Journal ArticleDOI
Recent primary production increases in arctic lakes
TL;DR: In this paper, a survey of six arctic lakes on Baffin Island (Nunavut, Canada), pronounced increases of spectrally-inferred chlorophyll a concentrations are consistently expressed in sediments deposited during the 20th century.
Journal ArticleDOI
Mountain lakes: Eyes on global environmental change

Strecker,Sudeep Chandra,David M. Walters,Daniel L. Preston,Neal Michelutti,Fabio Lepori,Sarah A. Spaulding,Kyle R. Christianson,John M. Melack,John P. Smol +19 more
TL;DR: A review and update of the growing body of research that shows that sediments in remote mountain lakes archive regional and global environmental changes, including those linked to climate change, altered biogeochemical cycles, and changes in dust composition and deposition, atmospheric fertilization, and biological manipulations can be found in this paper.
Journal ArticleDOI
Experimental calibration of lake-sediment spectral reflectance to chlorophyll a concentrations: methodology and paleolimnological validation
TL;DR: In this article, the spectral properties of sedimentary chlorophyll a using visible-near infrared reflectance (VNIR) spectroscopy were determined from a dilution series (n = 10) involving incremental additions of pulverized modern algae to a lake sediment matrix of low organic content.
