Remote-sensing and classification of benthic landscapes for satellite derived bathymetry

Bathymetry is a crucial variable for many researches, such as monitoring of the coral ecosystems. Traditional bathymetric measurements are made by echo-sounder, a type of sonar, measuring water depth from sea surface. Nevertheless, this acquisition process ...

Dynamic response of an embedded block impacted by aerated high-velocity jets

Anton Schleiss, Rafael Xavier Meriade Duarte

Uplift of blocks from the rock mass at the bottom of plunge pools is the main process of the scouring phenomenon caused by high-velocity jet impact. Although the influence of water and rock on dynamic block ejection has been investigated, no systematic res ...

Feeding behaviour of a benthic species (Ammonia tepida) under oxic and anoxic conditions: TEM-NanoSIMS correlation

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

More and more marine areas are subjected to depleted-O2 concentration, mainly due to eutrophication induced by human activities. These phenomena affect benthic ecosystems, in particular continental shelves and coastal areas where the renewal of the bottom ...

Morphology of pillow-hollow and quilted-cover bedforms in Lake Geneva, Switzerland

David Andrew Barry, Ulrich Lemmin, Yosef Akhtman, Nicolas Le Dantec, Dragos Constantin

Extensive areas of the bottom of Lake Geneva are covered with bedforms that have been referred to as pillow-hollows and quilted-cover pattern by prior observers, as well as with sediment waves and trenches. These structures are decimeter to meter scale. A ...

On the link between ocean biota emissions, aerosol, and maritime clouds: Airborne, ground, and satellite measurements off the coast of California

Athanasios Nenes

Surface, airborne, and satellite measurements over the eastern Pacific Ocean off the coast of California during the period between 2005 and 2007 are used to explore the relationship between ocean chlorophyll a, aerosol, and marine clouds. Periods of enhanc ...

Small-scale turbulence and vertical mixing in Lake Baikal

Alfred Johny Wüest

The water column of Lake Baikal is extremely weakly-but permanently-stratified below 250 m. Despite the thickness of this relatively stagnant water mass of more than 1000 m, the water age (time since last contact with the atmosphere) is only slightly more ...

Enhanced mixing in narrows: A case study at the Mainau sill (Lake Constance)

Alfred Johny Wüest

Previous work has identified bottom currents as a significant source of turbulence in stratified lakes. Sills may therefore be a major factor determining overall turbulent diapycnal (vertical) exchange in lakes with multi-basin hypolimnia. In order to inve ...

Boundary versus internal diapycnal mixing in stratified natural waters

Alfred Johny Wüest

Using the fluorescent dye uranin, tracer release experiments to study the contribution of bottom boundary mixing to diapycnal transport in stratified natural waters were performed in Lake Alpnach (central Switzerland) during 1992-1995. A first experiment i ...
