Extreme events, trends, and variability in Northern Hemisphere lake-ice phenology (1855–2005)

Autor: N. G. Granin, Johanna Korhonen, Gesa A. Weyhenmeyer, David M. Livingstone, John J. Magnuson, Olaf P. Jensen, Kenton M. Stewart, Glenn A. Hodgkins, Barbara J. Benson, Virginia M. Card

Publikováno v: Climatic Change. 112:299-323

Often extreme events, more than changes in mean conditions, have the greatest impact on the environment and human well-being. Here we examine changes in the occurrence of extremes in the timing of the annual formation and disappearance of lake ice in

An automated method to monitor lake ice phenology

Autor: G. Marzec, Donald C. Pierson, Barbara J. Benson, Lauri Arvola, Kurt Pettersson, Gesa A. Weyhenmeyer, Thorsten Blenckner, H. Markensten, Kathleen C. Weathers, David M. Livingstone, Timothy K. Kratz

Publikováno v: Limnology and Oceanography: Methods. 9:74-83

A simple method to automatically measure the date of ice-on, the date of ice-off, and the duration of lake ice cover is described. The presence of ice cover is detected by recording water temperature just below the ice/water interface and just above

Large geographical differences in the sensitivity of ice-covered lakes and rivers in the Northern Hemisphere to temperature changes

Autor: Markus Meili, Olaf P. Jensen, Gesa A. Weyhenmeyer, John J. Magnuson, David M. Livingstone, Barbara J. Benson

Publikováno v: Global Change Biology. 17:268-275

Based on a unique dataset of more than 50 000 observations of ice phenology from 1213 lakes and 236 rivers in 12 different countries, we show that interannual variations in the timing of ice-on and ...

Frontiers in Ecology and the Environment, 8(4), 193-200. doi: 10.1890/080130. UC Berkeley: Retrieved from: http://www.escholarship.org/uc/item/0s0015wm

Sensor networks promise to transform and expand environmental science. However, many technological dif- ficulties must be overcome to achieve this potential. Partnerships of ecologists with computer scientists and engineers are critical in meeting th

Coherence between lake ice cover, local climate and teleconnections (Lake Mendota, Wisconsin)

Autor: William G. Hyzer, Hector R. Bravo, Reza Namdar Ghanbari, Barbara J. Benson, John J. Magnuson

Publikováno v: Journal of Hydrology. 374:282-293

Summary Ice duration has shortened and the ice-off date has become earlier for Lake Mendota from 1905 to 2000 as air temperatures have warmed and snowfall has increased. In addition, the ice record has cyclic components at inter-annual and inter-deca

Spatial analysis of ice phenology trends across the Laurentian Great Lakes region during a recent warming period

Autor: Virginia M. Card, Patricia A. Soranno, Olaf P. Jensen, Martyn N. Futter, Kenton M. Stewart, Barbara J. Benson, John J. Magnuson

Publikováno v: Limnology and Oceanography. 52:2013-2026

We examined spatial patterns of trends in ice phenology and duration for 65 waterbodies across the Great Lakes region (Minnesota, Wisconsin, Michigan, Ontario, and New York) during a recent period of rapid climate warming (1975–2004). Average rates
