Model of primary production, including circulation influences, in Lake Superior

Anthropogenic climate change has altered primary productivity in Lake Superior

Anthropogenic climate change has the potential to alter many facets of Earth's freshwater resources, especially lacustrine ecosystems. The effects of anthropogenic changes in Lake Superior, which is Earth's largest freshwater lake by area, are not well documented (spatially or temporally) and predicted future states in response to climate change vary. Here we show that Lake Superior experienced...

Annual Production and Production: Biomass Ratios for Three Species of Stream Trout in Lake Superior Tributaries

—We made estimates of annual production of stream trout in two Lake Superior tributaries in northeastern Minnesota in 1977-1978. The Caribou River (total alkalinity, 34 mg/L as CaCO3) drains pan of the north shore of Lake Superior in an igneous rock geology. The Blackhoof River (total alkalinity, 83 mg/L) drains glacial drift and lake clay at the western end of Lake Superior. Annual production ...

Methods of substructuring in lake circulation dynamics

A semi-implicit semi-spectral hydrodynamic primitive equation model is used in combination with a substructuring technique to study wind-induced motions and tracer di€usion in the homogeneous and strati®ed Lake Constance. An impulsively applied spatially uniform wind is applied in the long direction of the lake (305° from True North) lasting inde®nitely. Tracer mass is released at various locat...

Primary Production of Lake Baikal and Its Significance for the Biolimnological Processes in the Lake

Modeling wind-driven circulation in Lake Ladoga

The goal of this paper is to present circulation patterns in Lake Ladoga occurring during episodes of strong wind. Hydrodynamics of episodic events are studied with a three-dimensional barotropic numerical model. Model results are presented for a variety of wind directions and, therefore, can be used for analysis of various biogeochemical data. As an illustration, an analysis of sediment distri...
