Lacustrine Groundwater Discharge Through Giant Pockmarks (Lake Neuchatel, Switzerland)
Frontiers in Water, 2020 Pockmarks are circular depressions on the floor of oceans and lakes and constitute potential hot spots of gas ebullition and/or groundwater discharge. Marine pockmarks are well-studied, whereas lacustrine pockmarks are virtually unexplored.

Using automatic calibration to improve the physics behind complex numerical models: an example from a 3D lake model using Delft3D (v6.02.10) and DYNO-PODS (v1.0) [PDF]
Geoscientific Model DevelopmentModels are simplified descriptions of reality and are intrinsically limited by the assumptions that have been introduced in their formulation. With the development of automatic calibration toolboxes, finding optimal parameters that suit the environmental

Persisting Water Droplets on Water Surfaces [PDF]
The Journal of Physical Chemistry B, 2010 Droplets of various liquids may float on the respective surfaces for extended periods of time prior to coalescence. We explored the features of delayed coalescence in highly purified water. Droplets several millimeters in diameter were released from a nozzle onto a water surface.

Tin contamination in sediments of Lake Zurich: source, spread, history and risk assessment
Swiss Journal of GeosciencesIndustrial activities of a silk dyeing factory in Thalwil, on the shore of Lake Zurich, Switzerland, caused extreme Sn contamination of lake sediments. In this study, we determine the contamination source, spread, and age using a multiproxy approach.

Adsorption characteristics of Cu (II) onto CaCl2 pretreated algerian bentonite
Materials Research Express, 2020 Calcium treated bentonite clay (CTBC) was prepared by CaCl _2 impregnation of Algerian bentonite clay. The prepared adsorbent was characterized and successfully used to remove Cu (II) ions from aqueous solutions at different conditions (pH, stirring time
