TS Must-Read – Yin and Harrison (2000) Geologic evolution of the Himalaya-Tibetan Orogen

Yin and Harrison (2000) puts together an exhaustive review of three decades of geological and geophysical investigations on the Himalayan-Tibetan orogen. This research supports the orogenesis started during the Cenozoic between 70 and 50 Ma ago as a consequence of the Indo-Asian collision following the closure of the Tethys ocean between Laurasia and Gondwana. Yin …[Read More]

Cryo History – Extent of South Georgia Glaciation during the Last Glacial Maximum

There has been considerable disagreement amongst researchers concerning the extent of South Georgia’s ice sheet during the Last Glacial Maximum (LGM). The sub-Antarctic islands (those below the polar front) may have been completely glaciated during previous glacials, and the last largest extent of the South Georgia ice sheet was during the LGM, about 21,000 years …[Read More]

A new glacier chronology from New Zealand

In this week’s blog, Levan Tielidze tells us about the new glacier history from the Southern Alps of New Zealand, an important piece of information to better understand the climatic history of Earth during the Quaternary, the current geologic period. Quaternary glaciations Geochronological dating of glacial moraines is useful for determining the extent and timing …[Read More]

Photo of sunset behind the drilling vessel JOIDES resolution

This year I was lucky enough to be part of International Ocean Discovery Program (IODP) Expedition 390 – South Atlantic Transect I – aboard the research vessel JOIDES Resolution which spent two months, from April to June, out in the South Atlantic, drilling into and sampling the upper oceanic crust and sediments. I sailed as …[Read More]

The Sassy Scientist – Challenging Yourself

Single author papers. You have seen those. Early in your career you look at them and think “Wow! This person must be really smart to publish all by themselves”. Later on, your reaction shifts to “Ahah! Look at this person, publishing the tenth paper by themselves! Nobody wants to be associated with this stuff!”. Whether …[Read More]

Lights out: cryosphere instruments perfectly placed to study solar eclipse

On 04 December 2021, only a handful of people in Antarctica were fortunate enough to experience a total eclipse. As well as spectacular views—including a brief window of totality that darkened the midnight sun for 2 minutes—this phenomenon is known to affect the flow of energy between the Northern and Southern hemispheres of the ionosphere. …[Read More]
