Daily observations from automated snowpack telemetry (SNOTEL) stations from within the drainage basin of the Great Salt Lake over the period from 1982 to 2007 are analyzed. The major finding is a shift toward an earlier date of peak snow water
equivalent (SWE) by around 15 days. This suggests increased chances of late-summer water shortages especially when combined with rapid recent population growth. Less freshwater is likely to be available to flow into the Great Salt Lake, increasing its

Directly dated Cucurbita from archaeological sites near Lake Huron expand the range and human usage of adventive, cultivated wild gourds or squash into the GreatLakes region, by 4000 C 14 yr BP. Although milder Hypsithermal climate may have been

Cloud-to-ground (CG) lightning observations for the warm season thunderstorms (May-September) of 1989 and 1990 were analyzed for the GreatLakes region. Diurnal variations in the frequency, spatial extent, flash density, amplitude, and polarity

δ18O measurements of benthic ostracodes are used to reconstruct the δ18O history of Lake Huron and Georgian Bay water between 10,600 and 7600 14C yr B.P. This δ18O record was calibrated using a comparison of the δ18O values of modern ostracodes

This paper analyses the history and the present state of shoreline control of Lake Balaton. The first shoreline control activities around Lake Balaton commenced during the last years of the 19th century. In recent years great amount of legislation
deals with the natural and artificial shaping of the shoreline of the Lake, and as a result a great number of studies and plans were created. According to the A., urgent actions need to be taken to stop illegal use of the shore (in filling, construction

Radiocarbon dates of plant materials from packrat middens, in conjunction with radiocarbon dates of archaeological materials, provide evidence that the last high stand of Pleistocene Lake Lahontan terminated before 12,070 yr B. P. This new
information suggests that the last major fluctuation in the level of Lake Lahontan was approximately synchronous with those of Lakes Bonneville and Russel, and that these three lakes probably responded contemporaneously to the same regional paleoclimatic
