Originally a soft accumulation of sand grains, shaped by the wind into large mounds and ridges, the dunes eventually turn into rock. As the sediments compact under their own pressure and expel any moisture and fluids retained within them, they become lithified and b ...[Read More]

Imaggeo on Mondays: Fly away, weather balloon

Some aspects of Earth Science are truly interdisciplinary and this week’s Imaggeo on Mondays photograph is testament to that. The maiden voyage of the research cruise SA Agulhas II offered the perfect opportunity to combine oceanographic research, as well as climate science studies. Raissa Philibert, a biogeochemistry PhD student, took this picture of the daily release of a weather balloon by mete ...[Read More]

GeoCinema Online: What a difference technology can make.

Advances in technology mean research that was unthinkable some years ago is now possible. For instance, geographically remote areas which were once out of reach have become more accessible through better (not always easier) transportation, so what we understand by ‘remote areas’ has changed significantly over time. The films in this edition of GeoCinema online are fascinating because they showcase ...[Read More]

Geosciences Column: Adapting to acidification, scientists add another piece to the puzzle

In the latest Geosciences Column Sara Mynott sheds light on recent research into how ocean acidification is affecting the California Current Large Marine Ecosystem. The findings, published in Biogeosciences, reveal large differences between the abilities of different animals to adapt and highlight the urgent need to understand the way a greater suite of species are responding… Large Marine Ecosyst ...[Read More]
