Imaggeo On Monday: The tree that gave birth to a forest

Imaggeo On Monday: The tree that gave birth to a forest

This 10 centimetre giant is a pioneer of marine conquest. All summer, glassworts (Salicornia europaea) will be rhythmically swept by the tide, gradually trapping seaborne sediment on the shores of Aberlady Bay in Scotland. The resulting elevation of the mudflat marks the start of a race of growth against waves, currents and sea level rise, eventually leading to the development of a salt marsh. How ...[Read More]

Imaggeo On Monday: C/2020 F3 (NEOWISE) – a memorable moment

Imaggeo On Monday: C/2020 F3 (NEOWISE) – a memorable moment

Around 17th July 2020, the core of the Neowise comet starting giving off a greenish-glow. At first I thought this strange colour was due to some glitch in my camera sensor (I used an entry-level DSLR), but other photos online also started reporting this greenish glow. It has since been speculated to be because of the formation of a new vent on the surface of the comet, discharging gaseous ions whi ...[Read More]

Imaggeo On Monday: Cassiopeia with Milky Way

Cassiopeia with Milky Way in the background on September 9th, 2020. The image was taken in north-eastern state of Germany (Mecklenburg – Lower Pomerania) near the Town of Jarmen. The region has little light pollution and the evening had a clear sky (sky quality measure was 21.15). The image was taken at about 22:00 hrs local time. An EOS 1100D with a 50/1.6 lens was used. The exposure time w ...[Read More]

Imaggeo on Mondays: Magnetic interaction

Space weather is a ubiquitous, but little known, natural hazard. Though not as tangible as a volcanic eruption, storm or tsunami wave, space weather has the potenital to cause huge economic losses across the globe. In Europe alone, the interaction of solar wind with our planet’s magnetosphere, ionosphere and thermosphere, could lead to disrutions to space-based telecommunications, broadcasti ...[Read More]

Geodesists on Tour: GPS measurements on Antarctica

Geodesists on Tour: GPS measurements on Antarctica

  Stories from the field – how exactly are those GPS data collected? The geodesy community at large benefits from the many science projects with open data policies.  A user simply has to navigate to a data portal, download the data, and within a matter of moments a world of possibilities opens up for potential research.  But where exactly do these data come from?  While scientific results get ...[Read More]

GeoTalk: Meet Joshua Dreyer, planetary scientist and the Planetary and Solar System Sciences Division’s Early Career Scientist Representative!

Hello Josh, thankyou for talking with us! Before we take off, could you tell us a little about yourself and your research? Hi Simon, thanks for inviting me! I’m a PhD student at the Swedish Institute of Space Physics (IRF) and Uppsala University, just started my third year. My research is focused on Saturn’s ionosphere (the region of the upper atmosphere with a significant amount of ch ...[Read More]

Imaggeo On Monday: International Space Station transiting the Sun

The International Space Station, a human-made, life-supporting habitat, and a most complex and unique scientific laboratory, orbits the Earth in only 90 minutes – that is 16 times a day! Even so, only occasionally, we earthlings have the privilege of seeing it’s dark outline against the much brighter surfaces of the Sun or Moon. Timing is of crucial importance if you want to see this, ...[Read More]
