Coffee break biogeosciences – climate change affects mountain plant’s sex ratios

Coffee break biogeosciences – climate change affects mountain plant’s sex ratios

As climate change progresses, widespread changes in phenotypes in many plant populations are bing observed by scientists around the world. For instance in alpine areas, dominant plant species on lower altitude are shifting towards higher altitude as they adapt to increasing temperatures, thereby competing with high-altitude native plant species. In a recent study by Petry et al. (2016) it was show ...[Read More]

Image of the week – The winds of summer (and surface fluxes of winter)

Antarctica is separated from the deep Southern Ocean by a shallow continental shelf. Waters are exchanged between the deep ocean and the shallow shelf, forming the Antarctic cross-shelf circulation: Very dense waters leave the shelf as Antarctic Bottom Water (AABW) that will then flow at the bottom of all oceans. Meanwhile, relatively warm water from the Southern Ocean, Modified Circumpolar Deep W ...[Read More]

Imaggeo on Mondays: an impressive testimony to the collision between Africa and Europe

The huge fold in the flank of the 2969 m high Dent de Morcles (in Waadtland Alps, Switzerland) is an impressive testimony to the collision between Africa and Europe (which began some 65 million years ago). The layers, originally deposited on the sea floor in a horizontal position, were compressed and shifted. The darker parts developed during the Tertiary period (66 million years ago). They are yo ...[Read More]

No need to be a superhero to momentarily escape your everyday life! For that you, can just rely on the EGU Cryosphere Blog, which cares for taking you on trips to all sorts of remote and cool places (OK, OK we have to admit that some of these places are indisputably cold :-)). The picture of this week was taken through the porthole of a boat in the middle of Isfjorden, one of the largest fjord in ...[Read More]

GeoTalk: Matt Taylor of ESA’s Rosetta mission

In November 2014, space exploration history was made. Millions of kilometres away, orbiting a piece of ice and rock, the European Space Agency’s (ESA) Rosetta mission sent its probe Philae to become the first spacecraft to soft-land on a comet. After the tense 7-hour wait that followed the separation from the main orbiter, a tweet confirmed that the little lander had successfully completed the fir ...[Read More]

Paper of the Month – Self-healing slip pulses in earthquake rupture

The “Paper of the Month” (PoM) blog series, recently launched by the Early Careers Scientists (ECS) representatives of the Seismology Division at EGU, aims to present particularly interesting, important, or innovative research articles in all fields related to seismology. While peer-reviewed articles published in the last 12 months are the primary targets, also older “classical” papers can make it ...[Read More]

GeoPolicy: 8 ways to engage with policy makers

Scientific research is usually verbally communicated to policy officials or through purposefully written documents. This occurs at all levels of governance (local, national, and international). This month’s GeoPolicy post takes a look at the main methods in which scientists can assist in the policy process and describes a new method adopted by the European Commission (EC) that aims to enhance scie ...[Read More]

Big Earth Science Data – Boon or bane?

We are in the era of Big Data. Big Data is a ‘hot’ topic. It is a popular term often associated with an increase in volume, variety and velocity of data. The Copernicus programme for example, the European Union’s flagship programme on monitoring the Earth’s environment using satellite and in-situ observations, anticipates a massive increase in satellite data volume. It is estimated tha ...[Read More]

The Solar System with planets and dwarf planets

Welcome on-board the blog of the PS division of the EGU ! You may not be familiar with the PS division and what it is about, so I’ll give you a tour. Most of the EGU divisions look towards the Earth, whether it is deep down the interior or right at the surface. Some look up to the atmosphere and the climate. Finally, there are two which look way up: PS and the Solar Terrestrial Sciences division ( ...[Read More]

Imaggeo on Mondays: The glacial landscape of Yosemite

Yosemite National Park, in California, is renowned for its beautiful and striking landscapes. So much so, this is the second time it has feature on the blog this summer. While our last post on the park focused on the ancient volcanic history of its landscape, in this post we fast forward to the Plesitocene (some 110,000 to 12,000 years ago) to discover more about how glaciers shaped Yosemite’s lan ...[Read More]
