The last two weeks have been action-packed, with ten schools from seven countries heading online to ask five fabulous geoscientists questions about anything from how the Earth works to what it’s like to be a scientist in the first ever I’m a Geoscientist, Get me out of here! competition. The aim of this thrilling fortnight was to let school kids interact with real geoscientists and challenge their ...[Read More]
Geosciences Column: Did Mediterranean salt change the global climate?
The latest Geosciences Column is brought to you by Annabel Slater, who describes a time of dramatic change in the Mediterranean. Slater shares the results of a recently published Climate of the Past study and sheds light on how – in the context of global climate – a little salt can go a long way… Many of us worry about the effects of too much salt on our health, not its effects on global climate. ...[Read More]
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]
Geosciences Column: Shifting the O in H2O
Wherever you are in the world’s oceans, you can identify particular bodies of water (provided you have the right equipment) by how salty they are. You can get a feel for how productive that part of the ocean is by measuring a few chemical components in the water column. And, year on year, you will see a recurring pattern in how things like temperature, salinity and oxygen content vary with depth. ...[Read More]
