Geosciences Column: Meshing models with the small-scale ocean

The latest Geosciences Column is brought to you by Nikita Marwaha, who explains how a new generation of marine models is letting scientists open up the oceans. The new technique, described in Ocean Science, reveals what’s happening to ocean chemistry and biology at scales that are often hard to model… Diving into the depths of the ocean without getting your feet wet is possible through biogeochemi ...[Read More]

Imaggeo on Mondays: Long-lived lakes have a lot to tell

The world’s oldest, deepest freshwater lake lies in southeast Siberia: Lake Baikal. Stretching some 600 kilometres across the Russian landscape, Baikal marks what the very early stages of a new ocean – an ancient rift that cleaved the centre of Asia apart throughout the Palaeozoic, Mesozoic and Cenozoic. Today, there are still signs of tectonic activity and the rift continues to diverge 4 mm furth ...[Read More]

Geosciences Column: Could plants be a cheap solution to soil contamination in developing countries?

There are many ways to remove contaminants from the land, but it is a constant battle for scientists to find better and cheaper ways to the job. Recent research published in Soild Earth suggests plants may present a solution – one that’s particularly promising for poor areas. Jane Robb describes the findings… Bolivia has a long and complicated mining history, going back to the 1500s. Untreated tai ...[Read More]

Defining the age of humans

We are currently changing our planet like never before. But do these changes deserve a new name? The Anthropocene – a geological period marking the length of time for which humans have had a significant impact on the planet – was first proposed in the 1980s. But the word has gained significant attention in recent years thanks to the popularising work of Nobel prize-winning chemist Paul Crutzen. Hu ...[Read More]
