Catching up with Iris van Zelst on everything outreach, science communication, and vlogging

Following from last week’s post on the Science Sisters series, this week we sit with outreach extraordinaire and EGU GD blog editor-in-chief Iris van Zelst to talk about all things scicom, vlogging and a new geological time game that you do not want to miss out on! Hi Iris, thanks for chatting with us! First …[Read More]

United Nations 101 for Hydrologists

United Nations 101 for Hydrologists

Did you feel the roar of water during the 2021 United Nations (UN) Climate Change Conference (aka COP 26) hosted at the Scottish Lowlands? It was the first time that the venue had a Water Pavilion in the COP history since 1995. The hashtags #Water4Climate with #COP26 were extremely popular in the social media channels. …[Read More]

Imaggeo On Monday: Intriguing artwork by heat-loving microbes

The geothermal area Sol de Mañana is part of the Altiplano–Puna volcanic complex shared between Bolivia and Chile. The area is characterized by volcanic activity and the sulphur springs host mud lakes and steam pools. The different colours stem from thermophilic, hyperthermophilic and acidophilic bacteria that colonize areas of varying temperatures.   Description by Julia Miloczki, …[Read More]

TS Must-Read – Fossen and Tikoff (1993): The deformation matrix for simultaneous simple shearing, pure shearing and volume change, and its application to transpression-transtension tectonics

With their milestone article in Journal of Structural Geology (Fossen and Tikoff, 1993)⁠ and its companion article in Tectonophysics (Tikoff and Fossen, 1993)⁠, the authors marked a step forward for the quantification of strain in the deep crust. These articles popularized a new approach, the deformation matrix. An easy solution to quantify strain in finite …[Read More]

Minerals and Art: a centuries-old connection

Minerals and Art: a centuries-old connection

Since ancient times, colours have been fundamental for artistic expression: pigments have always been created from fruits, leaves-flowers, and minerals. During the centuries, new material discoveries and techniques increased the shades we can still see and use nowadays. Once upon a Prehistoric time… El Castillo Cave, in Spain, is one of the earliest known cave …[Read More]

Camp Century re-visited: sediment from the bottom of a Cold War ice core reveals Greenland’s warm past

Camp Century re-visited: sediment from the bottom of a Cold War ice core reveals Greenland’s warm past

A Cold War nuclear-powered military base inside the Greenland Ice Sheet sounds like science fiction, but the science that came out of this U.S. army installation was anything but fiction. In last week’s EGU CR blog post, Paul Bierman and Amanda Schmidt discussed the advances made by the U.S. military in operating across the Greenland …[Read More]
