Using stable nitrogen isotopes to evaluate the relative importance of external and internal nitrogen loadings on phytoplankton production in a shallow eutrophic lake (Lake Mikata, Japan)
a shallow eutrophic lake phytoplankton production
2014/4/2
The seasonal variability of the stable nitrogen isotope (d15N) in phytoplankton and dissolved inorganic
nitrogen (DIN) in the shallow, eutrophic Lake Mikata was examined to assess the relative import...
Recent lake ice-out phenology within and among lake districts of Alaska, U.S.A.
lake districts of Alaska
2014/4/2
The timing of ice-out in high latitudes is a fundamental threshold for lake ecosystems and an indicator of
climate change. In lake-rich regions, the loss of ice cover also plays a key role in landsca...
A mechanistic-based framework to understand how dissolved organic carbon is processed in a large fluvial lake
bacterial growth primary production hydrodynamic regime photodegradation residence time ecosystem-based model
2014/4/1
Dissolved organic carbon (DOC) plays a fundamental role in the ecology of aquatic systems. Our current
understanding of the DOC dynamic in fluvial systems, however, is mostly based on empirical...
Lake trophic status can be determined by the depth distribution of sediment phosphorus
Lake trophic status sediment phosphorus
2014/4/4
In this meta-analysis, we examine how sediment phosphorus (P) burial pattern may be related to trophic state.
We present sediment P profiles from 94 lakes that demonstrate fundamental differences in ...
Double-Diffusive Convection and its Implications for the Temperature and Salinity Structure of the Ocean and Lake Vanda
Double-Diffusive Convection Salinity Structure Temperature Lake Vanda
2009/4/3
Recently, Fedorov has attempted to interpret some temperature and salinity profiles in the northeast Atlantic, as reported by Zenk, in terms of the results of laboratory experiments in double-diffusiv...
Theoretical Aspects of Wind-Driven Currents in a Sea or Lake of Variable Depth with No Horizontal Mixing
Wind-Driven Currents Variable Depth with No Horizontal Mixing
2009/4/3
Steady-state wind-driven circulations in a basin of variable depth, with only vertical turbulent mixing, are considered. The geostrophic flow away from the coast is determined for an arbitrary bottom ...
The Coastal Boundary Layer in Lake Ontario：Part II. The Summer-Fall Regime
Coastal Boundary Layer Lake Ontario The Summer-Fall Regime
2009/4/3
Field observations on coastal currents near Oshawa on the north shore of Lake Ontario during summer and fall are described. The technique of observations (flag-station chain) has been given in Part I,...
The Coastal Boundary Layer in Lake Ontario. Part I: The Spring Regime
Lake Ontario Coastal Boundary Layer Spring Regime
2009/4/3
Originally prompted by a desire to search for theoretically predicted “coastal jets,” an extensive series of observations on currents in the coastal zone near Oshawa, in Lake Ontario, were carried out...
An Ekman Model of Coastal Currents in a Lake or Shallow Sea
Ekman Model Coastal Currents Shallow Sea
2009/4/2
Coastal currents are investigated by use of asymptotic solutions in a steady-state barotropic lake or shallow sea of variable depth, with only vertical eddy viscosity and zero Rossby number. Earlier w...
Measurements of the vertical component of the temperature gradient in Powell Lake show phenomena similar to those observed in the ocean. The gradient is an irregular function of depth, with temperatur...
Coastal current observations taken at five locations in Lake Ontario during IFYGL, in periods of summer stratification, are presented and interpreted in terms of a linear dynamical model. Wind-stress ...
Verification of Numerical Models of Lake Ontario：Part I. Circulation in Spring and Early Summer
Numerical Models Lake Ontario Early Summer
2009/3/26
Data from the 1972 International Field Year on Lake Ontario have been used to test the performance of three-dimensional hydrodynamical models of large lakes. The models vary with regard to computation...
Spring Thermocline Behavior in Lake Ontario During IFYGL
Spring Thermocline Behavior Lake Ontario During IFYGL
2009/3/26
A dynamical analysis is presented of some observations made during the International Field Year on the Great Lakes (IFYGL) on the north shore of Lake Ontario at Oshawa. The data analyzed relate to wat...
Some Characteristics of Nearshore Currents along the North Shore of Lake Ontario
Nearshore Currents North Shore of Lake Ontario
2009/3/26
In three periods during 1970 representative of spring, summer and fall, the horizontal currents off Oshawa in Lake Ontario were measured at distances of 3, 6, 11 and 16 km offshore. All records were s...
Two time-dependent “vertical cross section models” are analyzed and applied to wind-driven currents in Lake Ontario. The models are: 1) a linear frictionless, two-level model, and 2) a numerical model...
