This mass-transport generated a large turbidite deposit, which is studied here by combining high- resolution seismic and sedimentary cores. This turbidite deposit correlates to a prominent onlapping unit in the seismic record. Attaining a maximum of 90 cm in thickness, it is longitudinally graded and thins out towards the end of the lake basin. Thickness distribution map shows that the turbidite extends over ∼8.5 km2 and has a total volume of 2.72⁎106 m3, which amounts to ∼8.7 yr of the lake's annual sediment input. It consists of normally graded sand to silt-sized sediment containing clasts of hemipelagic sediments, topped by a thin, white, clay-sized layer. The source area, the exact dating and the possible trigger of this turbidite deposit, as well as its flow mechanism and ecological impact are presented along with environmental data (river inflow, wind and lake-level measurements). -

KG, Sonderflughafen Oberpfaffenhofen, D-82205 Gilching, Germany - [email protected] KEY WORDS: Inland water, Case II water, lakes, MERIS, water constituents ABSTRACT: The physically based Modular Inversion & Processing System (MIP) is used in an automized processing chain for inland water constituent retrieval from MERIS level 1B data. Preprocessing routines are used to automatically convert the ESA generic data products into MIP input data format. Water/land masking, atmospheric correction and water constituent retrieval are accomplished by simple batch executables from MIP. The accuracy of the constituent retrieval mainly depends on the spectral fit between the image input data and the radiative transfer model results extracted from a database. Therefore, thresholds and initial values for model fitting have to account for all occurring lake specific temporal variations and need careful adjustment. 1. INTRODUCTION Heege, 2000), using the Modular Inversion & Processing System (MIP) (Heege and Fischer, 2004). Monitoring of water quality in lakes is required as an integral part of water resource management, in order to guarantee the In this work, a processing chain to automatically derive water sustainable use of water and to track the effects of constituents from MERIS level 1B data for Swiss lakes is built anthropogenic influences.

An opportunity for that arose when I booked on for the European Castles Tours "Three Corners of Europe – Black Forest, Alsace and Switzerland". That tour was designed for air travel to and from Zurich, so there was an easy way to add an extension of my own. The last full day of the tour was at Lucerne, and I was able to plan my extension starting there. I didn't want to repeat everything I'd done before, but I did know there was a magic region where I'd love to spend some more time. The Bernese Oberland in central Switzerland extends south into the Bernese Alps. Its mixture of mountains, lakes, and valleys has made it very popular, not only for sightseeing but also for hiking and active sports, both winter and summer. I visited the most famous sites on an earlier tour. This was a more relaxed visit. I stayed in Interlaken, the regional transportation hub, and made day excursions from there. The photos from my longer tour are in the Switzerland-1 and -2 PDFs, and the ones from the first part of this trip are on the "Three Corners" page. -

Whitefish (Coregonus spp.) from Lake Thun, Switzerland, display a high prevalence of macroscopical gonad malformations including fusions to the musculature, segmented gonads and intersex condition. The aim of the present study was to evaluate whether the gonad morphological changes in Lake Thun whitefish are caused by genetic factors, environmental factors (water, diet) or “gene environment” × interaction. We performed two independent experiments of a three-year duration in which we reared whitefish from fertilization until adulthood and tested the possible causative factors using a matrix design: (i) genetics—comparing the prevalence of gonad malformations in whitefish of different genetic origin reared under identical environmental conditions (same diet, same water, same experimental facility); (ii) environment—comparing the prevalence of gonad malformations in whitefish of the same genetic origin reared in different water sources and/or fed with different diets; and (iii) gene-environment interaction—comparing the prevalence of gonad morphological alterations in relation to the combinations of genetics and environmental factors. -

Quaternary Glaciation History of Northern Switzerland
Quaternary Science Journal GEOzOn SCiEnCE MEDiA Volume 60 / number 2–3 / 2011 / 282–305 / DOi 10.3285/eg.60.2-3.06 iSSn 0424-7116 E&G www.quaternary-science.net Quaternary glaciation history of northern switzerland Frank Preusser, Hans Rudolf Graf, Oskar keller, Edgar krayss, Christian Schlüchter Abstract: A revised glaciation history of the northern foreland of the Swiss Alps is presented by summarising field evidence and chronologi- cal data for different key sites and regions. The oldest Quaternary sediments of Switzerland are multiphase gravels intercalated by till and overbank deposits (‘Deckenschotter’). Important differences in the base level within the gravel deposits allows the distin- guishing of two complex units (‘Höhere Deckenschotter’, ‘Tiefere Deckenschotter’), separated by a period of substantial incision. Mammal remains place the older unit (‘Höhere Deckenschotter’) into zone MN 17 (2.6–1.8 Ma). Each of the complexes contains evidence for at least two, but probably up-to four, individual glaciations. In summary, up-to eight Early Pleistocene glaciations of the Swiss alpine foreland are proposed. The Early Pleistocene ‘Deckenschotter’ are separated from Middle Pleistocene deposition by a time of important erosion, likely related to tectonic movements and/or re-direction of the Alpine Rhine (Middle Pleistocene Reorganisation – MPR). The Middle-Late Pleistocene comprises four or five glaciations, named Möhlin, Habsburg, Hagenholz (uncertain, inadequately documented), Beringen, and Birrfeld after their key regions. The Möhlin Glaciation represents the most extensive glaciation of the Swiss alpine foreland while the Beringen Glaciation had a slightly lesser extent. The last glacial cycle (Birrfeld Glaciation) probably comprises three independent glacial advances dated to ca.
