A new hydrological climate-impact study by Nina Köplin and colleagues, in the European Geosciences Union journal Hydrology and Earth System Sciences, investigates the impacts of climate change on forest expansion and glacier retreat in Switzerland. This study raises important questions as to whether or not land cover changes should be considered as climate change impacts on hydrological systems, N ...[Read More]
Geosciences Column: Stitching the seafloor together
You’re standing on a mountain peak, with a fabulous field site before you. Wanting to capture the moment, you take out your iPhone, snap a dozen pictures and your mobile stitches them together beautifully – a nice record to show your colleagues back in the office. Unfortunately, not all field sites are so easy to capture – especially when you need to do a little science with the images. Seafloor p ...[Read More]
Geosciences Column: Dating a bivalve
Just as the rings on a tree can be used to determine its age, the bands on a bivalve’s shell can tell us the how long it’s been around for. Warm, food-filled waters lead to greater growth in the summer and low plankton abundance (the principle food source for filter-feeding molluscs) leads to limited growth during the winter months – hence the banding. But pinning down the age of a bivalve m ...[Read More]
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]
