“…For Müggelsee (Berlin, Germany), a 1°C increase in winter air temperature resulted in a reduction of ice coverage by about 17 days [59]. This reduction in ice coverage is similar to that recorded for North American lakes (Lake Mendota, 12.7 days; Grand Traverse Bay, Lake Michigan, 15.5 days [50]).…”

“…1, 2). The NAO-related early ice break-up (or the total lack of an ice cover) in both Lake Erken and Müggelsee induced earlier and more pronounced algal spring blooms [57,58,59], which thus were related to the NAO as well [58,72]. It is likely that the enhanced phytoplankton biomass in Heiligensee [30] and Plußsee [66] after mild winters also was associated with the NAO.…”

“…In addition to earlier breakup dates, later freeze-up dates were observed for Lake Suwa (Japan) [54] and for Mirror Lake (New Hampshire) [52].

“…A variety of studies documented that ice cover periods of lakes have shortened remarkably during the past decades in Wisconsin [49,50,51] Specifically, significant changes toward earlier ice break-up dates happened both around 1890 and around 1980 at Lake Mendota (Wisconsin) [49].

Impacts of climate warming on freshwater ecosystems have been documented recently for a variety of sites around the globe. Here we provide a review of studies that report long-term (multidecadal) effects of warming trends on thermal properties and plankton dynamics in northern hemispheric lakes. We show that higher lake temperatures, shorter periods with ice cover, and shorter stagnation periods were common trends for lakes across the hemisphere in response to the warmer conditions. Only for shallow dimictic lakes was it observed that deepwater temperatures decreased. Moreover, it became evident that phytoplankton dynamics and primary productivity altered in conjunction with changes in lake physics. Algal spring blooms developed early and were more pronounced in several European lakes after mild winters with short ice cover periods, and primary productivity increased in North American lakes. Effects of elevated temperatures on zooplankton communities were seen in an early development of various species and groups, as is documented for cladocerans, copepods, and rotifers in European lakes. Furthermore, thermophile species reached higher abundance in warmer years.Obviously, the nature of responses is species specific, and depends on the detailed seasonal patterning of warming. Complex responses such as effects propagating across trophic levels are likely, indicating that observed climateecosystem relationships are not generally applicable. Nonetheless, the picture emerges that climate-driven changes in freshwater ecosystems may be synchronised to a certain extent among lakes even over great distances if climatic influences are not masked by anthropogenic impacts or differences in lake morphology. Macro-scale climatic fluctuations -such as the North Atlantic Oscillation or the El Niño-Southern Oscillation -were identified as the most important candidates responsible for such coherence, with the former predominating in Europe and the latter in North America. We emphasise, however, that the driving mechanisms and the future behaviour of these oscillations are Gerten and Adrian: Climate Warming on Freshwater Ecosystems TheScientificWorldJOURNAL (2002) 2, 586-606 587 rather uncertain, which complicates extrapolation of observed effects into the future. Thus, it is necessary to quantify the most important climate-ecosystem relationships in models of appropriate complexity. Such models will help elucidate the multiple pathways climate affects freshwater ecosystems, and will indicate possible adverse effects of a warmer future climate.KEY WORDS: climate change, freshwater ecosystems, North Atlantic Oscillation, El Niño-Southern Oscillation, lake ice, long-term, phytoplankton, zooplankton, large-scale synchronization DOMAINS: freshwater systems, ecosystems and communities, atmospheric systems, ecosystems management INTRODUCTIONWeather and climate regulate physical, chemical, and biological processes in freshwater ecosystems at all time scales [1].

“…The ice regime of Lake Müggelsee is typical for lowland shallow lakes of temperate regions and is characterized by irregular freezing on interannual scale. In cold years, the ice-cover period can last from 3 to 4 months, typically from the end of December to the beginning of March, whereas the mild winters are either completely ice-free or characterized by occasional ice buildup (Adrian and Hintze 2000).…”

Basin-scale internal waves in the bottom boundary layer of ice-covered Lake Müggelsee, Germany

We performed high-resolution temperature measurements under ice cover in Lake Müggel-see, Germany, during the winter of 2005-2006. Intense seiche-like temperature oscillations developing after the ice-on have been encountered in a thin water layer above the sediments. The oscillations were initiated immediately after lake freezing by the release of the potential energy of the thermocline slope and existed for several weeks without appreciable external forcing. The oscillations were associated with a basinscale internal waves existing in the lower stratified part of the water column. The weakness of the density stratification under ice ensured the long wave periods, exceeding the period of geostrophic inertial oscillations at the lake's latitude. As a result, two frequency peaks were present in the oscillations corresponding to two rotational waves, one of Kelvin-wave type and another of Poincaré type wave. The rotational character provided long dissipation times of the waves and allowed the oscillations to persist in lake several weeks. Temperature measurements in the upper several centimeters of the sediment demonstrated that oscillations of the near-bottom temperature produced vertical density instability and pore-water convection in the upper sediments.
