What’s geodiversity you ask? It’s short for geological diversity - the diversity of the natural parts of our planet that aren’t alive. The rocks, soils, sediments, landforms, and hydrological features, for example, and the processes that create and change these and other non-living features. Geodiversity isn’t just the stuff we see on the land. It’s underwater too. Let’s take a peek at just five spectacular undersea features that make up some of our World’s geodiversity.
750+ Oil Slicks Found in Mediterranean Sea
A new report released at the Our Ocean Conference in Greece by SkyTruth, a nonprofit conservation technology organization, identified 757 oil slicks covering 1.9 million hectares in the Mediterranean Sea between July 2020 - January 2024. Most of these slicks were discharged from vessels in transit.

Tiny crustaceans discovered preying on live jellyfish during harsh Arctic night
Scientists used DNA metabarcoding to show for the first time that jellyfish are an important food for amphipods during the Arctic polar night in waters off Svalbard, at a time of year when other food resources are scarce. Amphipods were not only observed to feast on ‘jelly-falls’ of dead jellyfish, but also to prey on live jellyfish. These results corroborate an ongoing ‘paradigm shift’ which recognizes that jellyfish aren’t a trophic dead-end but an important food for many marine organisms.
