At Hengifoss, Iceland’s third-highest waterfall, it tumbles fiercely down thick, dark layers of lavas erupted from volcanoes some 18 to 2.58 million years ago, during a period of geological time known as the Tertiary. Eruptions are rarely continuous; during hiatuses in the extrusion of lavas, ash is able to ...[Read More]

During the severe rains that occurred between May 12 and 13, 2017 in the Atacama Region (Northern Chile) the usually dry Copiapó R ...[Read More]

While at this year’s General Assembly in Vienna, Keri McNamara, one of the EGU’s press assistants, spoke to a number of female geoscientists (at different career stages), to get their perspective on what being a female in geosciences is like. At this year’s EGU General Assembly I decided to construct a blog out of conversations I had with several women in geoscience, to learn about the ...[Read More]

This image was taken during the Arctic Ocean 2016(AO16) expedition that ventured to the central regions of the Arctic Ocean, including the North Pole. It shows a pressure ridge, or ice ridge, as viewed from onboard the deck of the icebreaker Oden. It was quite striking that the ice ridge resembled an image of a spine – sea ice being a defining characteristic of the broader Arctic environment and b ...[Read More]
