“…Ice-out dates correlate most strongly with air temperatures in the month or two before ice-out (Tramoni et al, 1985;Palecki and Barry, 1986;Robertson et al, 1992;Livingstone, 1997). Many studies in the last 15 years have used Northern Hemisphere lake ice-out dates as climatic indicators (Tramoni et al, 1985;Palecki and Barry, 1986;Rousteenoja, 1986;Robertson et al, 1992;Assel and Robertson, 1995;Anderson et al, 1996;Livingstone, 1997;Magnuson et al, 2000). In Northern Hemisphere mid-latitude areas such as New England, ice-out dates can serve as useful indicators of late winter and early spring climate change.…”
