Lake metabolism: Relationships with dissolved organic carbon and phosphorus
Recent literature has suggested that for many lakes and rivers, the respiratory breakdown of organic matter (R) exceeds production of organic matter by photosynthesis (gross primary production [GPP])
Lake metabolism and the diel oxygen technique: State of the science
Significant improvements have been made in estimating gross primary production (GPP), ecosystem respiration (R), and net ecosystem production (NEP) from diel, “free‐water” changes in dissolved oxygen
A model of carbon evasion and sedimentation in temperate lakes
Lakes process terrigenous carbon. The carbon load processed by lakes may partially offset estimates made for terrestrial net ecosystem exchange (NEE). The balance within lakes between carbon burial
Ecological and Social Dynamics in Simple Models of Ecosystem Management
Simulation models were developed to explore and illustrate dynamics of socioecological systems. The ecosystem is a lake subject to phosphorus pollution. Phosphorus flows from agriculture to upland
Integrating aquatic and terrestrial components to construct a complete carbon budget for a north temperate lake district
The development of complete regional carbon (C) budgets for different biomes is an integral step in the effort to predict global response and potential feedbacks to a changing climate regime. Wetland
Controls of δ13C‐DIC in lakes: Geochemistry, lake metabolism, and morphometry
We investigated δ13 carbon (C)‐dissolved inorganic carbon (DIC) values in 72 lakes from diverse regions using literature data as well as new measurements for 32 lakes. δ13C‐DIC varied broadly among
Salting our freshwater lakes
TLDR
It is found that in Midwest and Northeast North America, most urban lakes and rural lakes that are surrounded by >1% impervious land cover show increasing chloride trends, and many lakes will exceed the aquatic life threshold criterion for chronic chloride exposure in the next 50 y if current trends continue.
Creating and maintaining high-performing collaborative research teams: the importance of diversity and interpersonal skills
Collaborative research teams are a necessary and desirable component of most scientific endeavors. Effective collaborative teams exhibit important research outcomes, far beyond what could be
Lake‐size dependency of wind shear and convection as controls on gas exchange
High‐frequency physical observations from 40 temperate lakes were used to examine the relative contributions of wind shear (u*) and convection (w*) to turbulence in the surface mixed layer. Seasonal
A temperature compensation method for CDOM fluorescence sensors in freshwater
The effect of temperature on CDOM fluorescence was investigated in dystrophic freshwaters of Wisconsin and in aqueous standards. Laboratory experiments with two commercial in situ fluorometers showed
