Hysteresis For Dummies – Why history matters

Julius Garbe December 4, 2020

Perhaps you have stumbled upon the word ‘hysteresis’ before, for example in connection with the stability behavior of our Earth’s large ice sheets and their long-term effect on global sea-level rise, or the long-term stability of the Atlantic Meridional Overturning Circulation, or even in another context outside earth/climate science. Or you might have come across this term during your studies, bu ...[Read More]

It’s Black in Marine Science Week!

Camille Gaynus December 2, 2020

Earlier this summer, as a global society we were reminded; our societies are riddled with inequalities. The deaths of Ahmaud Arbery, George Floyd, Breonna Taylor and other Black people over minor infringements of the law if any, flooded our news feeds; Black people like myself were reminded of just how dangerous our world is. The remnants of slavery and Jim-Crow era segregation are still felt in t ...[Read More]

Moving a country for a new job is a big step, but at the same time changing from an industry job to academics is definitely a leap in the unknown. This week Arushi Saxena, currently a post-doc at the University of Florida, writes about her experience taking these two steps at the same time. As geodynamicists, we are well aware that our numerical models are a function of the input parameters. A re ...[Read More]

Why is research in Antarctica so important?

Hazel Gibson December 1, 2020

On the 1st December 1959 the Antarctic Treaty was signed by 12 nations, setting aside nearly 10% of the Earth “forever to be used exclusively for peaceful purposes… in the interests of all mankind.” In the years that followed more and more countries signed the agreement, until today when the agreement has been signed by 54 countries around the globe. In 2010, the Foundation for ...[Read More]

Life as a “dry” oceanographer – studying Earth’s oceans from your laptop

Yackar Mauzole December 1, 2020

I didn’t always know that I would become an oceanographer when I grew up, but I knew I would be doing ‘Science’. I was born and raised in Paris, France. While growing up, I was always interested in Science, from watching documentaries about the universe or nature, to attending science events at museums. While Science is very wide and encompasses many fields of research, I wasn’t too cl ...[Read More]

Imaggeo On Monday: Desert Varnish, Antarctica Style

Martha Cary Eppes November 30, 2020

This photograph highlights the oxidized surface of diorite boulders, which fall from the ice at the base of the Mullins Glacier in Beacon Valley, Antarctica when the ice moves directly from a solid state into a gas state, without becoming a liquid in between (a process called sublimation). The particular features (morphology) of the varnish and the desert pavement of this unique environment are re ...[Read More]
