Last week, a team of cryospheric scientists published a paper in The Cryosphere that showed how tiny plates of ice can lead to spurious estimates of sea ice thickness. This week, we’re featuring their findings, as well as some spectacular sea ice images in the latest in our Imaggeo on Mondays series… Viewing the poles from above is a stunning sight – a seemingly endless expanse of bril ...[Read More]

Imaggeo on Mondays: Long-lived lakes have a lot to tell
The world’s oldest, deepest freshwater lake lies in southeast Siberia: Lake Baikal. Stretching some 600 kilometres across the Russian landscape, Baikal marks what the very early stages of a new ocean – an ancient rift that cleaved the centre of Asia apart throughout the Palaeozoic, Mesozoic and Cenozoic. Today, there are still signs of tectonic activity and the rift continues to diverge 4 mm furth ...[Read More]

Imaggeo on Mondays: Quartz lawns and crystal flowers
Petrologists spend a large part of their time peering down microscopes at wafer thin slices of rock to work out what they’re made of and how they were formed. What lies on the other side of the lens can be an incredibly beautiful pattern, a kaleidoscope of colour, or stark bands of black and white, all of which provide clues to the rock’s history, and the history of the landscape it came from. Ber ...[Read More]

GeoTalk: Steven Smith on fossil faults and fantastic faulting
This week in GeoTalk, we’re talking to Steven Smith, a Lecturer from the University of Otago. Steven takes us on an Earth-shaking journey, explaining how ancient faults reveal what’s happening under the Earth’s surface and delving into the future of fault zone research. First, could you introduce yourself and tell us a little about what you are currently working on? Last September I started as a L ...[Read More]

GeoTalk: The mantle and models and measurements, oh my! Talking geophysics with Juan Carlos Afonso
This week in GeoTalk, we’re talking to Juan Carlos Afonso, a geophysicist from Macquarie University, Sydney. He explains how a holistic approach is crucial to understanding tectonic processes and how a little “LitMod philosophy” can go a long way to achieving this… First, could you introduce yourself and tell us a little about what you are currently working on? My name is Juan Carlos Afonso and I’ ...[Read More]

Geosciences Column: Shifting the O in H2O
Wherever you are in the world’s oceans, you can identify particular bodies of water (provided you have the right equipment) by how salty they are. You can get a feel for how productive that part of the ocean is by measuring a few chemical components in the water column. And, year on year, you will see a recurring pattern in how things like temperature, salinity and oxygen content vary with depth. ...[Read More]
