Geologic carbon storage is unlikely to trigger large earthquakes and reactivate faults through which CO2 could leak

Zoback and Gorelick [(2012) Proc Natl Acad Sci USA 109(26): 10164-10168] have claimed that geologic carbon storage in deep saline formations is very likely to trigger large induced seismicity, which may damage the caprock and ruin the objective of keeping ...

Validating formulas for the prediction of ascent speed and mass transfer coefficient for liquid oil droplets and gas bubbles under pressure

Jeremy Samuel Arey, Jonas Gros

Several different formulas exist to predict the ascent speed of gas bubbles and oil droplets released in deep waters. Similarly, different formulas are also available to predict the mass transfer coefficient of compounds dissolving into water during ascent ...

Double diffusion in saline Powell Lake, British Columbia

Alfred Johny Wüest

Powell Lake contains a deep layer of relic seawater separated from the ocean since the last ice age. Permanently stratified and geothermally heated from below, this deep layer is an isolated geophysical domain suitable for studying double-diffusive convect ...

Characterizing the spatial snow depth distribution in mountainous terrain

Michael Lehning, Henning Löwe, Tobias Jonas, Thomas Grünewald

Spatial snow depth information is an essential component for many applications such as the computation of snow melt rates in hydrologic applications or the energy balance in meteorological or climate models. Due to computational constraints, small-scale di ...

Diffusive-type of double diffusion in lakes - a review

Alfred Johny Wüest, Martin Schmid

This chapter is a contribution in honour of Gerhard H Jirka, who has been fascinated by the amazing variety of small-scale structures that nature surprises us with, particularly in stratified natural waters. Here, we focus on the diffusive regime of double ...

The ancient evolutionary origins of Scleractinia revealed by azooxanthellate corals

Anders Meibom, Jaroslaw Hubert Stolarski

Background: Scleractinian corals are currently a focus of major interest because of their ecological importance and the uncertain fate of coral reefs in the face of increasing anthropogenic pressure. Despite this, remarkably little is known about the evolu ...

Uranium-series dating and growth characteristics of the deep-sea scleractinian coral: Enallopsammia rostrata from the Equatorial Pacific

Anders Meibom

The deep-sea coral, Enallopsammia rostrata, a member of the Dendrophylliidae family, is a major structure-forming species that creates massive dendroid colonies, up to 1 m wide and 0.5 m tall. Living colonies of E. rostrata have been collected using the PI ...

Double-diffusive convection in Lake Kivu

Alfred Johny Wüest, Martin Schmid

Double-diffusive staircases with a total of 230-350 mixed layers and sharp interfaces were observed in nine microstructure temperature profiles measured during February 2004 in Lake Kivu. The presence of these staircases at depths. 120 m indicates that dia ...

Physical and biogeochemical limits to internal nutrient loading of meromictic Lake Kivu

Alfred Johny Wüest, Beat Mueller, Martin Schmid, Bernhard Wehrli

Lake Kivu is one of the large African Rift lakes situated between the Democratic Republic of the Congo and Rwanda. In its permanently stratified hypolimnion, unusually high methane concentrations have increased further in recent decades. Because methanogen ...

Effect of environmental conditions and skeletal ultrastructure on the Li isotopic composition of scleractinian corals

Anders Meibom

The lithium isotope compositions (Li-7/Li-6) and Li/Ca ratios of shallow-water and deep-sea corals (Porites lutea, Cladocora caespitosa, Lophelia pertusa and Desmophyllum cristagalli) were measured using a Cameca ims 1270 ion microprobe. The two C. caespit ...
