  • Lake hydrology, water quality and ecology impacts of altered river–lake interactions: advances in research on the middle Yangtze river

    Water and mass exchange between rivers and lakes are key processes that maintain the health of the ecology of river–lake systems. Alteration to river–lake interactions have great impacts on water and mass balances. Naturally connected to the middle Yangtze River are the Poyang Lake and Dongting Lake, which are the largest and the second largest freshwater lakes in China. The operation of the ...

  • Great Lakes need great Data Buoys

    One recently finished project was performed by the University of Wisconsin and has comprised the depolyment of two data buoys which are both furnished with a multifunctional Lufft WS501-UMB. These weather ...

  • Assessment of treatment capabilities of Varthur Lake, Bangalore, India

    Manmade waterbodies have traditionally been used for domestic and irrigation purposes. Unplanned urbanisation and ad-hoc approaches have led to these waterbodies receiving untreated sewage. This enriches and eutrophies the waterbody. A physico-chemical and biological analysis of sewage-fed Varthur Lake in Bangalore was carried out and its treatment capabilities in terms of BOD removal, nutrient ...

  • Monitoring mixing dynamics in Toolik Lake, Alaska

    Toolik Lake is 130 miles south of Prudhoe Bay in northern Alaska. It is one of the main monitoring sites of the Arctic Long-Term Ecological Research (LTER) project and a site for studies led by Sally MacIntyre of the University of California investigating the linkages between hydrodynamics and ecosystem function. Both studies are funded by the U.S. National Science Foundation. It is classified as ...

  • Phytoplankton and bacterioplankton abundances and community dynamics in Lake Erhai

    The composition and seasonal variation of the phytoplankton and bacterioplankton community were investigated, and SPSS and redundancy analysis (RDA) were used to explore the relationship between the phytoplankton and bacterioplankton community dynamics in the typical plateau Lake of Lake Erhai from July 2009 to April 2010. Obvious seasonal variation of phytoplankton was observed, and the ...

  • Lake Water Quality Model with Focus on Cyanobacteria

    ABSTRACTThe cause of cyanobacteria’s growth and dominance in certain eutrophic lakes is explored via a water quality model application. The one-dimensional lake water quality model includes nitrogen, phosphorus, silica, three phytoplankton groups and zooplankton. Lake Washington was used as the case study due to its unique history of eutrophication during a large wastewater nutrient loading ...

  • Case study - Control and monitor algae in a lake

    As part of the Clearwater PMPC project, 2 MPC Buoys were deployed in the Skrzyneckie Małe Lake to test the performance of this unique technology. The Challenge: Control and Monitor Toxic Algal Blooms The ClearWaterPMPC project was initiated by LG Sound and funded by "Research for SMEs" within the EU 7th Framework Programme. The goal of the ClearWaterPMPC (Predicting, ...

  • Widespread Plastic Pollution Found in Great Lakes Tributaries

    Tiny pieces of harmful plastic, called microplastics, are prevalent in many rivers that flow into the Great Lakes, according to a study published today in the journal Environmental Science & Technology. Results are also illustrated on a new USGS microplastics website. Microplastics ...

  • Enumeration of Cryptosporidium spp and Giardia spp (oo)cysts in a tropical eutrophic lake: The municipal lake of Yaounde

    The biodynamic of Cryptosporidium spp. oocysts and Giadia spp. cysts have been assessed in the municipal lake of Yaounde, which is an artificial eutrophic lake that has been constructed on the Mingoa stream of the Mfoundi River Basin of Cameroon. The oocysts were identified by the Ziehl-Neelsen method while the cysts were identified by the Lugol iodine coloration. The values obtained suggest an ...

  • Managing Great Lakes Water Levels Adaptively in Response to Changing Climate Conditions

    The Laurentian Great Lakes contain an abundance of fresh water, collectively representing approximately 20% of the fresh surface water available globally. Despite the enormity of this resource, water levels and flows in the Great Lakes are subject to fluctuations caused by changing climate conditions that have cascading impacts on the coastal ecosystem and the regional economy. Proactive ...

  • Comparing different methods of calculating volume-weighted hypolimnetic oxygen (VWHO) in lakes

    In the limnological literature there is no standard method for calculating hypolimnetic volumes using temperature profile data. Consequently, calculations of hypolimnetic dissolved oxygen concentrations differ based on the method chosen. This study examined the differences in calculations of volume-weighted hypolimnetic oxygen (VWHO) concentrations based on different methodologies and profile ...
