Coral, wanted dead and alive; a brief excursion into the world of coral science

Today we have a guest post from Dr. Peter Tomiak who delves into the life and death of corals… I completed my undergraduate degree in Biology and Geology at the University of Bristol in 2008. Subsequently I undertook a sponsored internship with Save The Elephants, in Samburu National Park Kenya, before starting a short term position alongside Prof. Adrian Lister at […]


Science snap (#31): Mammatus clouds

After all the thunderous weather this weekend and being British, I thought I’d do a weather themed science snap. Don’t bolt yet; it’s a volcanic-weather themed! This is a picture of mammatus clouds following the eruption of Mount St. Helens in 1980. These clouds are pretty rare, unusual and distinctive. Formally, the Glossary of Meteorology […]

Science Snap (#29): African Fairy Circles

Originally posted on the EGU blog network If you’re wandering among the arid desert that stretches from Angola to South Africa, you may notice the ground pot-marked by millions of circular barren patches. These striking features are known as “Fairy circles”, and can grow up to 15 meters in diameter. Tall grasses often surround these circles, further […]

Science Snap (#28): The Eye of the Sahara

Originally posted on the EGU blog network Surrounded by thousands of square miles of ubiquitous desert, the “Eye of the Sahara” peers out from the Earth’s surface and at nearly 50 km wide, its easily visible from space too. The “Eye of the Sahara” is known as a Richat Structure, a geological feature consisting of […]

Science Snap (#28): Brandberg Massif, Namibia

Originally posted on the EGU blog network Brandberg Massif is Namibia’s highest mountain, but if you look from above, you’ll notice it’s no ordinary one. Brandberg is a single mass of granite that pierced its way through the Earth’s crust into the Namib Desert. Looking at the Landsat 7 image, Brandberg is a circular dark […]

Science Snap (#25): Vesuvius, Andy Warhol

Originally posted on the EGU blog network Quite simply, volcanoes are inspiring. I’ve yet to meet someone who disagrees. The majestic volcanic landscape has thus been an inspiration to many an artist and author, whether intentional or not. Furthermore, artwork itself can be a valuable tool to help decipher and understand eruptions and their effects […]

Science Snap (#24): The psychedelic Zambezi flood plain

Originally posted on the EGU blog network This colourful image shows the Zambezi River’s floodplain in Zambia. The image was created from three acquisitions from Envisat’s radar instrument that were merged together. Each acquisition was assigned a colour and when combined show changes in the floodplain between each satellite acquisition. The white patch of pixels in […]

Science snap (#23): Pacaya Volcano

Originally posted on the EGU blog network Pacaya Volcano, Guatemala, is almost continuously erupting, making it one of Guatemala’s most active volcanoes and a popular tourist destination. The volcano last erupted on March 2, 2014, shown in the image here taken by the MODIS instrument on the Terra satellite. Although the volcano has been kicking off since January, in March […]

Science Snap (#20): Sentinal-1A Dress Rehearsal

Originally posted on the EGU blog network On the 3rd April 2014 the new satellite Sentinel-1 will be launched from French Guinea into space. It’s the satellite that has the InSAR community pretty excited as it will provide free Earth Observation data covering nearly all the world’s volcanoes. Once the satellite is launched and is sat […]

Science Snap (#15): Big freezes

Originally posted on the EGU blog network Satellite images are not just wonderful for science, they also capture public interest during periods of intense and news grabbing weather. Earlier this month North America was gripped by a prolonged Arctic Chill, plunging the continent into freezing temperatures and smashing temperature records in the process. Consecutive satellite […]
