Paleogeography and the Northern Hemisphere Oceanic Gateways

Paleogeography and the Northern Hemisphere Oceanic Gateways

Eivind Straume a Postdoctoral fellow at the Department of Geological Sciences within the Jackson School of Geosciences explores how the opening and closing ocean gateways have influenced the Earth’s climate in the past.   Changes in Earth’s geography due to tectonic plate motions and mantle convection influence climate evolution on geological timescales. Over millions of years, continen ...[Read More]

The Sassy Scientist – Faulty Segments

The Sassy Scientist – Faulty Segments

`Segmentation fault’. One of the most annoying things ever to appear on our screens. Right up there with `fftw.h not found’. Compilation errors are the (rock-hard) bread and (rancid) butter of any of us that need to debug write codes. Tahina is deeply down the rabbit hole and asks: Why does my code not compile? Dear Tahina, I am assuming you already thoroughly searched Stack Exchange f ...[Read More]

Do lower mantle slabs contribute in generating the Indian Ocean geoid low?

Do lower mantle slabs contribute in generating the Indian Ocean geoid low?

The Indian Ocean Geoid Low is an enigmatic phenomenon in geodynamics. Many brain-storming hypotheses have been proposed in the last few decades to explain this geoid low. One popular idea argues that the high density lower mantle slabs contribute to this geoid low. Recent discoveries have shown that low-density anomalies from the African LLSVP region could have a more substantial influence on crea ...[Read More]

The Sassy Scientist – The Nonsense Of Open Research

The Sassy Scientist – The Nonsense Of Open Research

Enzo submitted his manuscript for review at one of those well-known, Earth science-niche journals. However, shortly thereafter he received an email by his editor that it was rejected. Reason being that not enough research was added in the manuscript. Furious, he bellows: When is my research open enough to be published? Dear Enzo, I know, right? It seems that over the past few years the need to giv ...[Read More]
