This week on GeoCinema Online, we’re taking a look at all things ocean, bringing what few people see straight to your desktop – or, for that matter, any other shiny viewing device you may posses! Take a dive and find out what plankton get up to in the microscopic world beyond our vision, what corals and communities lie in the cold deep and how oceanographers are working to better under ...[Read More]
GeoTalk: Simon Mudd
Today in GeoTalk, we’re talking to Simon Mudd, an exceptional and forward-thinking geomorphologist. First, could you introduce yourself and let us know a bit about what you are currently working on? I am lecturer in Landscape Dynamics at the University of Edinburgh, where I have been since 2007. Before that I was a post-doc at Vanderbilt University, in Nashville Tennessee. I received my PhD from V ...[Read More]
Geosciences Column: Larvae, Climate and Calcification
The absorption of atmospheric CO2 by the oceans results in a decline in ocean pH, hence ‘ocean acidification’, and reduces the availability of carbonate. This presents a problem to calcifying organisms (those that deposit calcium as either calcite or aragonite as hard parts) because they cannot produce their shells, valves (in the case of bivalves), or tests (in the case of diatoms) as readily. To ...[Read More]
Geosciences Column: Perfecting Palaeogeographic Reconstructions
We model the changes in the geographic location of continents via paleogeographic reconstructions. However, the current methodology for generating these reconstructions is not without problems! Publication of palaeogeographic reconstructions is scarce, probably resulting from the difficulties associated with generating them. Conventional reconstructions are presented as static maps which have poor ...[Read More]
