Secchi depth has been measured in Lake Tahoe an average of every 12 d since July 1967. Because of the unusual clarity of the lake, Secchi depth measurement is responsive to small changes in light‐attenuating particles, and the record exhibits strong variability at the seasonal, interannual, and decadal scales. Using recently developed methods of applied time‐series analysis, the mechanisms of change were delineated at each scale. The seasonal pattern is a bimodal one, with two minima at… 
Patterns of spatial and temporal variability of UV transparency in Lake Tahoe, California‐Nevada
Lake Tahoe is an ultra-oligotrophic subalpine lake that is renowned for its clarity. The region experiences little cloud cover and is one of the most UV transparent lakes in the world. As such, it is
Determining long-term water quality change in the presence of climate variability: Lake Tahoe (U.S.A.)
A time series model of Secchi depth for Lake Tahoe is developed incorporating a mechanistic understand- ing of interannual variability with sufficient simplicity to allow data-based parameter estimation, and offers a means for determining compliance with water quality standards when precipitation anomalies may persist for years.
The Warming of Lake Tahoe
SummaryWe investigated the effects of climate variability on the thermal structure of Lake Tahoe, California-Nevada, 1970–2002, and with principal components analysis and step-wise multiple
Evidence for nutrient enrichment of high‐elevation lakes in the Sierra Nevada, California
Long‐term measurements (1983–2001) of nutrients and seston in Emerald Lake (Sierra Nevada, California) have revealed ecologically significant patterns. Nitrate, both during spring runoff and during
Climate change impacts on lake thermal dynamics and ecosystem vulnerabilities
Using water column temperature records collected since 1968, we analyzed the impacts of climate change on thermal properties, stability intensity, length of stratification, and deep mixing dynamics
An extraordinary upwelling event in a deep thermally stratified lake
A unique combination of temporal and spatial measurements provides a description of an extraordinarily large upwelling event in Lake Tahoe, CA‐NV. The 4 d event, which engulfed half of the lake's
Interannual Variability in Irish Sea Turbidity and Relation to Wind Strength
An existing method for estimating the turbidity of the Irish Sea has been used to estimate the mean annual water clarity in the Irish Sea from 1987–97. The method is based on a strong relationship
Basin-scale internal wave dynamics during a winter cooling period in a large lake
[1] Basin-scale internal waves are examined using a combined field observation and 3-D numerical approach. The field site, Lake Tahoe (CA-NV) during winter, is characterized by the presence of a weak


Mixing and the dynamics of the deep chlorophyll maximum in Lake Tahoe
Chlorophyll-temperature profiles were measured across Lake Tahoe about every 10 days from April through July 1980. Analysis of the 123 profiles and associated productivity and nutrient data
Interannual fluctuations in primary production: Meteorological forcing at two subalpine lakes
Meteorological factors are associated with most of the interannual variability in primary production at both Castle Lake, California (4 l”N, 122%‘) and Lake Tahoe, California-Nevada (39”N, 12O”W). At
Natural versus human-caused variability of water clarity in the Southern California Bight
This paper examines the spatial and temporal variability of two optical properties (percent transmissivity and Secchi disk depth) measured near three areas in the Southern California Bight in which
Quaternary History of Lake Tahoe, California-Nevada
Lake Tahoe, California-Nevada, occupies a graben near the crest of the Sierra Nevada. The lake basin was formed by faulting and volcanism about 2 m.y. ago and contains more than 400 m of sediments.
Primary productivity, nutrients, and transparency during the early onset of eutrophication in ultra‐oligotrophic Lake Tahoe, Califomia‐Nevada1
For more than half a century, the trophic status of water bodies has been of interest to Iimnologists and oceanographers alike. This report demonstrates the close, inverse relationship between
Temperature, Water Chemistry, and Optical Properties of Crater Lake
ABSTRACT Water temperature, water chemistry, and optical properties of Crater Lake were studied from 1983 to 1991. In winter and spring, wind energy and convection mixed the water column to a depth
Long‐term trends in Secchi depth in the Baltic Sea
dNutrient loads to the Baltic Sea have increased during the last century, and primary production has probably also risen. However, the evidence of such a rise is circumstantial, and most of the
Long-term change in Lake Tahoe (California-Nevada, U.S.A.) and its relation to atmospheric deposition of algal nutrients
Bounds for the doubling times of the TN pool and the TN: TP ratio demonstrate that loading is fast enough to cause the observed changes, and suggest that interannual variability in nitrate and total acid-hydrolyzable phosphorus is large enough to disguise trends of the expected magnitude.
Decadal, Interannual, and Seasonal Variability in Enrichment Bioassays at Lake Tahoe, California–Nevada, USA
The response of Lake Tahoe water to macronutrient supplementation has been assayed with inorganic 14C uptake since the 1960s, and on the decadal and annual scale, an effect of spring mixing depth on the size of the bioassay response could be observed.
