Contribution of standardized indexes to understand groundwater level fluctuations in response to meteorological conditions in cold and humid climates

Understanding the fluctuations in groundwater levels in response to meteorological conditions is challenging, especially given the slow transit time associated with groundwater reservoirs and the short duration of time series for groundwater levels. Nevert ...

River ecosystem metabolism and carbon biogeochemistry in a changing world

Tom Ian Battin, Enrico Bertuzzo, Luis Gómez Gener

River networks represent the largest biogeochemical nexus between the continents, ocean and atmosphere. Our current understanding of the role of rivers in the global carbon cycle remains limited, which makes it difficult to predict how global change may al ...

Evolution of stream and lake water temperature under climate change

Alfred Johny Wüest, Damien Bouffard, Wolf Hendrik Huwald, Adrien Michel, Bettina Schaefli, Carl Love Mikael Råman Vinnå, Martin Schmid

This report presents past observations and projects the future development of water temperature in Swiss lakes and rivers. Projections are made until the end of the 21st century using the CH2018 climate scenarios. Besides climate change effects on temperat ...

Warming of lowland Polish lakes under future climate change scenarios and consequences for ice cover and mixing dynamics

Sebastiano Piccolroaz

Study region: The study region comprises 25 lowland Polish lakes in the northern part of the country. The studied lakes provide domestic, industrial and agricultural water supply, and are major attractions for tourism, thus playing a significant role in th ...

Temperature of artificial freshwater recharge significantly affects salinity distributions in coastal confined aquifers

David Andrew Barry, Li Pu

Artificial freshwater recharge is commonly used to mitigate seawater intrusion and restore salinized aquifers in coastal zones. While the temperature of recharged freshwater often differs from that of aquifers, effects of temperature differences on water f ...

Persistence of bioconvection-induced mixed layers in a stratified lake

Alfred Johny Wüest, Damien Bouffard, Oscar Rodrigo Sepúlveda Steiner

In situ observations of biophysical interactions in natural waters typically focus on physical mechanisms influencing biological activity. Yet, biological activity can also drive physical processes in aquatic environments. A community of photoautotrophic, ...

Changing nutrient cycling in Lake Baikal, the world's oldest lake

Sebastiano Piccolroaz

Lake Baikal, lying in a rift zone in southeastern Siberia, is the world's oldest, deepest, and most voluminous lake that began to form over 30 million years ago. Cited as the "most outstanding example of a freshwater ecosystem" and designated a World Herit ...

Nutrients influence seasonal metabolic patterns and total productivity of Arctic streams

Luis Gómez Gener

The seasonality of gross primary production (GPP) in streams is driven by multiple physical and chemical factors, yet incident light is often thought to be most important. In Arctic tundra streams, however, light is available in saturating amounts througho ...

Insights into the dynamics of the deep hypolimnion of Lake Geneva as revealed by long-term temperature, oxygen, and current measurements

Ulrich Lemmin

In order to identify or shed light on dominant long-term processes of the deep hypolimnion of Lake Geneva (309 m depth), time series of temperature and horizontal currents and profiles of temperature and oxygen, taken for over a decade in the deepest part ...

Mixing processes and their ecological implications: From vertical to lateral variability in stratified lakes

Oscar Rodrigo Sepúlveda Steiner

The physical environment of natural waters influences biogeochemical processes to generate specific ecological niches, promoting biophysical interactions. Bacteria and phytoplankton communities can form spatial structures, such as layers and patches. The p ...
