The authors have mapped the three-dimensional motion of a fish onto various electronic music performance gestures, including loops, melodies, arpeggio and DJ-like interventions. They combine an element of visualization, using an LED screen installed on the back of an aquarium, to create a link between the fish’s motion and the sonified music. This visual addition provides extra information about the fish’s role in the music, enabling the perception of versatile and developing auditory structures during the performance that extend beyond the sonification of the momentary motion of objects. © 2016 ISAST.

It has been hypothesised that in sand seas where multiple dune generations occur, each generation represents a distinct terrestrial response to contrasting palaeoatmospheric circulation conditions (Lancaster N, Kocurek G, Singhvi A, Pandey V, Deynoux M, Ghienne J-Fet al.(2002) Late Pleistocene and Holocene dune activity and wind regimes in the western Sahara Desert of Mauritania. Geology 30: 991-994). However, reconstructing dunefield accumulation and preservation chronologies has often utilised a limited suite of samples because of the difficulties realised in accessing unconsolidated aeolian sands, which has limited the capacity to test this hypothesis. In the eastern United Arab Emirates, artificial excavation for quarrying and construction have generated a unique opportunity to examine and sample the internal structures of dune systems, and to generate data to test the hypothesis of dune generational development. This paper presents new data and chronologies from a multigenerational analysis of dune accumulation in the northeast dunefield of the Rub' al-Khali. A complex developmental history during the Holocene is revealed, which does not fully conform to the notion of each dune generation forming in distinct palaeoclimatic phases, since the age ranges represented in the accumulation of secondary dunes is also found within a longer suite of accumulation ages from the underlying megaridges. © SAGE Publications 2011.

The carbon curse is a new theory, related to but distinct from the resource curse. It states that fossil-fuel rich countries tend to follow more carbon-intensive developmental pathways than [if they were] fossil-fuel poor countries, due to a hitherto unappreciated syndrome of causal mechanisms. First, fuel rich countries emit significant amounts of CO2 in the extraction of fuel and through associated wasteful practices such as gas flaring. Second, easy access to domestic fuel in such countries leads to crowding-out effects for their energy mix and economic structure (for example, abundant oil may displace other fuels from the energy mix and lead to the "Dutch Disease"). Third, fuel abundance weakens the economic incentive to invest in energy efficiency. Fourth, governments in fuel rich countries are under considerable pressure to grant uneconomic fuel consumption subsidies, which further augments the carbon intensity of their economic output. Due to the combined effect of these causal mechanisms, it is genuinely difficult for fuel rich countries to evade carbon-intensive developmental pathways. And yet there are remarkable exceptions like Norway. Such positive outliers indicate that the carbon curse is not destiny when appropriate policies are adopted. © 2013 Elsevier Ltd.

The hyper-arid Namib Desert is an ancient desert of great lithological diversity. Weathering plays a key role in landscape evolution in the Namib which, in spite of its aridity, has a number of sources of moisture - rainfall, fogs, dews and groundwater seepage - which enhance weathering. Among the weathering processes that have been the subject of recent study in the central Namib are salt, thermal and lichen weathering which, in often complex associations of processes, contribute to the array of small scale weathering features found on marble and granite outcrops here. At the landscape scale weathering in the central Namib is also highly interrelated with erosion and the development of geochemical sediments (calcrete, gypcrete, tufas etc), whilst weathering 'hotspots' are thought to be important sources of fine sediment production. Over the long term weathering has played important roles in landscape evolution here which, despite localized weathering hotspots, has been very slow for much of the Cenozoic. © 2011 Elsevier Ltd.

Dayas, small depressions found on limestone surfaces in drylands, have been revealed by remote sensing to be surprisingly widespread. Examples are known from North Africa, East Africa, Namibia, Kenya, South Africa, the High Plains of the USA, the Pampas of Argentina, the Nullarbor Plain of Australia, and various parts of the Middle East. They display a range of morphologies, but some of them, in the USA, Namibia, Australia and Algeria appear to have been developed as a result of solutional etching into former interdunal depressions. Most are developed on Tertiary limestones or on calcretes. © 2010 Gebr. Borntraeger Verlagsbuchhandlung, Stuttgart. Germany.
