Ocean hypoxia: what does the increase of dead zones mean for marine life?

Ocean hypoxia: what does the increase of dead zones mean for marine life?

When runoff from farmland and urban areas enters our streams and rivers, it carries a heavy load of fertilizers and nutrients. These substances accumulate and flow into our coastal oceans, triggering a series of reactions that can create hypoxic ‘dead zones’. Dead zones are low-oxygen, or hypoxic, areas in the world’s oceans and lakes. Because most organisms need oxygen to live, very f ...[Read More]

Can our oases outlast the dry spell of desertification?

Can our oases outlast the dry spell of desertification?

Ever wondered how fast our planet is losing its footing? Imagine this: every time you blink, four football fields’ worth of fertile soil vanish into thin air. According to the UN, that’s a mind-boggling 100 million hectares gobbled up by land degradation each year! But when this happens in dry regions, it morphs into something even more sinister: desertification. Karina Lima, a climate ...[Read More]

GeoTalk: meet Alessandro Silvano, winner of the 2024 Ocean Sciences Division Outstanding ECS Award!

Alessandro Silvano

Hello Alessandro. Thank you for joining me for this edition GeoTalk! Could you tell our readers about your background before we dive in?  I am an oceanographer based at the University of Southampton (UK). I am interested in polar oceanography and ice-ocean interactions. The focus of my work is to understand the processes that control ocean heat transport toward rapidly-melting Antarctic glaciers. ...[Read More]
