Summary
LTER - Long-Term Ecological Research Program/North Temperate Lakes (NTL)
LTER/NTL013 [Summary adapted from the LTER Core Data Set Catalog]:
Questions relating to the flux of solute elements to and from lakes
require accurate water budgets. Evaporation rates are a critical
component of the water budget of lakes. An instrumented raft is put
... on the lake over the ice-free season to measure micrometeorological
parameters from which evaporation can be calculated. Raft
measurements of relative humidity and air temperature (2 m height),
wind velocity (1, 2, and 3 m heights), and water temperatures at 1-m
intervals are combined with measurements of total long-wave and
short-wave radiation data from a nearby shore station to determine
evaporation by the energy budget technique. Comparable evaporation
estimates from mass transfer techniques are calibrated against energy
budget estimates to produce a lake-specific mass transfer coefficient
for use in measuring humidities over longer periods of time using the
mass transfer technique alone. Evaporation is calculated using both
energy budget and mass transfer techniques.
Special Comments: Data are measured every minute, averaged to one
hour periods and recorded using Campbell dataloggers. Twenty-four
averages are calculated and stored from the one hour averages.
The North Temperate Lakes (NTL) site is affiliated with the Center for
Limnology at the University of Wisconsin, Madison. The NTL site
focuses its research on north temperate lake ecosystems in the
Northern Highland Lakes District of Wisconsin. The Northern Highland
Lakes District, has an area of approximately 10,000 sq. km. and has
one of the highest concentrations of lakes in the world. Lakes range
in size from 0.1 to 1,500 ha, in depth from 1 to 33 m, and in
fertility from oligotrophic to eutrophic. Other representative
limnological conditions include: rainwater dominated, groundwater
dominated and drainage lakes; dystrophic lakes; lakes with varved
sediments, winterkill lakes, temporary and permanent forest ponds, and
reservoirs. Lakes are influenced by strong seasonality and are usually
ice covered from late November to late April. Lakes within the
Northern Highland exhibit near-natural water quality conditions.
Nearly 80% of the land area and two-thirds of the lake frontage are
protected.
