Imaggeo on Mondays: The waxing Earth

Imaggeo on Mondays: The waxing Earth

These incredible images of Earth were acquired from the European MSG-2 satellite on July 21, 2009. The MSG, which stands for Meteosat Second Generation, satellites are operated as a series of satellites which continually orbit our planet, capturing detailed images of Europe, Africa and parts of the Atlantic and Indian Ocean every 15 minutes. The data acquired …[Read More]

When mountains collapse…

When mountains collapse…

Jane Qiu, a grantee of the Pulitzer Center on Crisis Reporting, took to quake-stricken Nepal last month — venturing into landslide-riddled terrains and shadowing scientists studying what makes slopes more susceptible to failure after an earthquake. The journey proved to be more perilous than she had expected. What would it be like to lose all …[Read More]

Geoscience hot topics – The finale: Understanding planet Earth

What are the most interesting, cutting-edge and compelling research topics within the scientific areas represented in the EGU divisions? Ground-breaking and innovative research features yearly at our annual General Assembly, but what are the overarching ideas and big research questions that still remain unanswered? We spoke to some of our division presidents and canvased their …[Read More]

Mars Rocks – introducing a citizen science project

Mars Rocks – introducing a citizen science project

GeoLog followers will remember our previous report on Citizen Geoscience: the exciting possibilities it presents for the acquisition of data, whilst cautioning against the exploitation of volunteered labour. This blog presents a Citizen Science platform that goes beyond data collection to analysis, specifically for geological changes in remote sensing imagery of Mars. Jessica Wardlaw, a Postdoctoral Research Associate …[Read More]

Imaggeo on Mondays: A fold belt within a grain

Imaggeo on Mondays: A fold belt within a grain

Tiny crinkly folds form the main basis of today’s Imaggeo on Mondays. Folding can occur on a number of scales; studying folds at all scales can reveal critical information about how rocks behave when they are squeeze and pinched, as described by Sina Marti, from the University of Basel. Although many geoscientists have seen such …[Read More]

Imaggeo on Mondays: Fly away, weather balloon

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 …[Read More]
