Sharkcano, a melting pot for biology

No, a Sharkcano is not a volcano that erupts sharks. IT IS WAY COOLER THAN THAT! It is a submarine volcano that hosts a diverse macro community in water that is much warmer and more acidic that the surrounding seawater.

Stop: Recovery Time!: Using volcanoes to model recovery of deep-sea communities

Deep sea communities are full of weird and wonderful animals that we don’t know much about, and human demand for sulfides may lead to deep sea mining near their habitat. We don’t know how they’ll respond to a disturbance, so these researchers looked at what happens after a natural disturbance: a volcanic eruption. Read on to find out what happened to the vent communities!

A 2.5 billion year old story about iron in the ocean, told by a rock

New light has been shed on the possibility of an alternative iron sink than previous thought prior to the oxygenation of the oceans 2.45 billion years ago. The findings could affect our interpretations of the early seawater chemistry, nutrient cycling, and trace metal distribution in the Precambrian.

A volcano, a tropical cyclone, and a computer model walked into a room…

Like with bad jokes, timing is everything. The punch line doesn’t make sense if you don’t know the back story, just like when mixing active volcanoes, tropical cyclones, and new volcanic smog dispersion models.
