In Part 1 we differentiated between (1) shallow-marine tide-related currents from (2) purely gravitational sediment-laden currents. We could add that the former are periodic, as they are controlled by the effect of the Moon and Sun gravitational fields on the oceanic water as the Earth revolves, while the latter are sort of ‘spontaneous’ currents driven …[Read More]

In a nutshell Tektonika is a community-led Diamond Open Access journal (DOAJ) for tectonics and structural geology launching in early 2022. The journal will publish high quality peer-reviewed research that is free for authors and readers, offering an alternative to long-standing publishing models that conceal knowledge dissemination behind paid subscriptions. Community involvement is at Tektonika’s …[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For August, the Divisions we are featuring are: Geodesy (G), Geodynamics (GD) and Earth and Space Science Informatics (ESSI). They are served by the …[Read More]
The solar eclipse of November 3, 2013, as observed from the MSG satellite, in geostationary orbit 36000km above the equator. The eclipsed area, where the shadow of the full Moon reached the Earth’s surface, moved over the Atlantic Ocean and Africa. This eclipse was classified as a hybrid eclipse because it started out as an …[Read More]
The Intergovernmental Panel on Climate Change (IPCC) prepares and publishes extensive Assessment Reports on the scientific, technical and socio-economic knowledge on climate change, including its impacts, future risks, and likely scenarios based on the actions that humanity takes. In their sixth Assessment Report (AR6), the IPCC’s certainty and warnings were clearer than ever. This month’s …[Read More]
There are several ways that we can classify glaciers. We can look at their shape, their size, their type of terminus, and many other features. A new characteristic has recently been gaining in popularity: artificiality. Yes, we now have a few artificial glaciers! Have you ever heard about them? They are glaciers whose behavior is …[Read More]
