Timelapse volcanoes in Google’s Earth Engine

With the marvels of technology and the generosity of Google and NASA, we can now sit back and watch the back catalogue of volcanic eruptions using the magnificent Google Earth Timelapse of Landsat images. Here are just a few that I have picked out.. Enjoy, and do send more suggestions! Anatahan, Marianas, erupted in 2005.  Anatahan Timelapse Chaiten, Chile.

Who should set the research agenda in Universities?

Universities are complex, organic institutions. Their heart is the academic hub of scholarship and research, sustained  by the ever-changing life-blood of students who come through to learn, to challenge, to grow, and ultimately to leave,  having left their mark on those who have taught them. The excitement of working in a University environment is the daily experience of being challenged to think ...[Read More]

Geosciences Column: Larvae, Climate and Calcification

The absorption of atmospheric CO2 by the oceans results in a decline in ocean pH, hence ‘ocean acidification’, and reduces the availability of carbonate. This presents a problem to calcifying organisms (those that deposit calcium as either calcite or aragonite as hard parts) because they cannot produce their shells, valves (in the case of bivalves), or tests (in the case of diatoms) as readily. To ...[Read More]

Imaggeo on Mondays: Spying on the Arctic

This week’s Imaggeo on Mondays is brought to you by the photographer himself, Fabien Darrouzet who captured the beautiful glacial landscape during a summer expedition to the Arctic.  This picture was taken in Svalbard (78° lat.) in June 2012. I was there for one week in order to observe the transit of the planet Venus in front of the Sun. I came here because at this time of the year, the Sun is sh ...[Read More]

Guest Post: Dr. Sam Illingworth – To Boldy Go

Satellites are now so ubiquitous in our lives that there is something of a precedent to take them for granted. A normal daily routine for may people across the world may include watching television (satellite) as you check your twitter account (satellite) and have a look at the weather (satellite), all before you’ve even eaten your breakfast (not a satellite); whilst for those of us in the remote ...[Read More]

Chaiten: anniversary of an eruption

Chaiten: anniversary of an eruption

May 1st marks the anniversary of the start of the first historical eruption of Chaiten, a small volcano in southern Chile, in 2008. A lot has been written on the eruption elsewhere, starting with Erik Klemetti’s eruptions blog which first reported on the event at the time. This is an opportunity to share some field photos, which I took during field visits to Chaiten in 2009. At the time of t ...[Read More]
