Friday Photo (83): Wildlife in the Field – Giant Millipede Inspects Stromatolites
A giant millipede kindly provides a scale for a photo of some stromatolites in the Nama group, Namibia. Microbial communities grow upwards towards the light. Each growth phases is cemented by carbonate grains that stick to the sticky EPS substance that the communities produce, forming layered stromatolite columns. The stromatolites pictured above formed 550 million …[Read More]

Geosciences Column: Tracing Toba
Large volcanic eruptions have a significant impact on the Earth’s climate as aerosols (including sulphur dioxide and water vapour), together with ash are released into the atmosphere and increase the amount of sunlight reflected back into space (the albedo). This increase in reflectance (or decrease in energy absorption) can cause widespread climatic cooling, known as …[Read More]

The last time I visited Colborne Quarry was before I had started …[Read More]
Imaggeo on Mondays: Vanishing Lakes and Dry Arctic Landscapes
The Koukdjuak Plains (south-west Baffin Island, Canada) form a vast postglacial marine plain that borders the Foxe Basin, an area that has been progressively uplifted due to glacio-isostatic rebound following the end of the last glaciation about 6600 years ago. The weight of glaciers on the Earth’s crust causes the ground to be depressed, which, …[Read More]
Historical Hazards: Lessons From Ancient Rome
The town of Pompeii was enveloped in ash during the eruption of Mount Vesuvius in 79AD. To the north of Pompeii lies the small, relatively unknown town of Herculaneum, where the ash fell hotter and deeper. Careful excavation by a team of archaeologists, led by Andrew Wallace-Hadrill, has revealed intricate details of daily life for …[Read More]
