Geosciences Column: Autofluorescence in polar regions – how and why?

Marine picoplankton, <2 µm, are one of the most ubiquitous fauna in the open ocean. These marine microorganisms are hugely important – being responsible for a significant proportion of oceanic net primary productivity. Researchers are able to track the evolution of their genomes and the transportation of these microorganisms by analysing ice cores, which offer the potential to study the evoluti ...[Read More]

Dust in the desert: The Skeleton Coast – Foggy, dusty & demanding – part 3 of 3

In this third instalment in this series our journey takes us into the Skeleton Coast. Synonymous with shipwrecks and known as “The Land God Made in Anger” to indigenous Bushmen this coastal desert has been protected as a National Park since 1971. Similar to many of Namibia’s National Parks, the Skeleton Coast does not allow anyone to stay overnight within its boundaries. However at over 16,000 km2 ...[Read More]

Imaggeo on Mondays: Monitoring the melt

Automatic weather stations (AWS) play a prominent role in making meteorological measurements in remote areas. These measurements can feed into climate models; providing better projections for rainfall, temperature and more. This peculiarly perched piece of equipment is just such a weather station: Out in the Swiss Alps, this AWS is making measurements of temperature, precipitation, wind speed, rel ...[Read More]
