[1] This paper uses the results from two multiseason numerical model simulations of Lake Michigan hydrodynamics to examine the relative effects of wind stress curl, topography, and stratification on large-scale circulation. The multiseason simulations provide a period long enough to encompass the full range of atmospheric and thermal conditions that can occur in the lake. The purpose of this pa...

Brackish water lake is home of peculiar organisms, as its salinity is middle of those of sea and fresh water. Its salinity changes sensitively with sea level, river flow rate and lake topography. Hinuma Lake is one of brackish water lakes in Japan and connects with the Pacific Ocean through a tributary and a major river. Therefore the inflow process of salt water to the lake is very complex. Th...

A 100-yr-long time series of water temperature measured just downstream of Lake Superior is used to produce proxy time series of open-lake temperature. This analysis suggests that open-water Lake Superior summer temperatures have increased by roughly 3.5uC over the last century, most of that warming occurring in the last three decades. Correspondingly, the length of the positively stratified se...

Metrics describing the shape and size of lakes, known as lake morphometry metrics, are important for any limnological study. In cases where a lake has long been the subject of study these data are often already collected and are openly available. Many other lakes have these data collected, but access is challenging as it is often stored on individual computers (or worse, in filing cabinets) and...

To quantify the effects of recent and potential future decreases in surface wind speeds on lake thermal stratification, we apply the one-dimensional process-based model MyLake to a large, shallow, polymictic lake, Võrtsjärv. The model is validated for a 3-year period and run separately for 28 years using long-term daily atmospheric forcing data from a nearby meteorological station. Model simula...

introduction lake terraces are geomorphological evidence of climate change during quaternary. location of these terraces location in different elevation shows paleo water lake level fluctuations. investigation about urmia lake terraces was conducted by bobek (1973).he found those terraces in 45-55 meter above urmia water level on that time. according to bobek, development of lake area in paleo ...

Long-term water temperature records are necessary for better understanding climate change impacts on freshwaters. We reconstruct summer water temperatures from three climatically sensitive mountain lakes in Austria using paleolimnological methods aiming to examine long-term thermal dynamics and lakes' responses to regional climate variability since the Little Ice Age. Our results indicate diver...

Subglacial Lake Whillans (SLW), West Antarctica, is an active component of the subglacial hydrological network located beneath 800 m of ice. The fill and drain behavior of SLW leads to long (years to decades) water residence times relative to those in mountain glacier systems. Here, we present the aqueous geochemistry of the SLW water column and pore waters from a 38-cm-long sediment core. Stab...

[1] We determined hydrogen isotope ratios of individual fatty acids in a sediment core from Blood Pond, Massachusetts, USA, in order to reconstruct climate changes during the past 15 kyr. In addition to palmitic acid (C16 n-acid), which has been shown to record lake water D/H ratios, our surface sediments and down core data indicate that behenic acid (C22 n-acid), produced mainly by aquatic mac...

We combine 'on-fault' trench observations of slip on the Polochic fault (North America-Caribbean plate boundary) with a 1200 years-long 'near-fault' record of seismo-turbidite generation in a lake located within 2 km of the fault. The lake record indicates that, over the past 12 centuries, 10 earthquakes reaching ground-shaking intensities ≥ VI generated seismo-turbidites in the lake. Seismic a...
