I recently accompanied an intrepid group of Cambridge alumni on board the Ocean Endeavour as we sailed a section of the fabled Northwest Passage from West Greenland to the western Canadian Arctic.Continue reading “Into the Northwest Passage: four billion years of Earth history”
In August 2018 I was lucky enough to join a CASP expedition to Bear Island, in the Norwegian High Arctic, as a field assistant and as part of my Part III project.
My journey to the arctic began as so many do, in Heathrow airport. We unloaded the minivan-sized taxi required to get all our gear to the airport, and I walked in to the entrance of Terminal 2 wearing a big coat, carrying two heavy gear bags and a rifle case. We drew some looks. I couldn’t help but feel excited and important.
Then I realised I had left my phone in the taxi. Panic descended.Continue reading “Tales from Bear Island: a month of Arctic fieldwork (or, four weeks without a phone)”
The Archean Eon (4–2.5 billion years ago) is one of the last great frontiers in our knowledge of the Earth. Plate tectonics is considered to have initiated during this time period, and large volumes of the continental crust formed, but fundamental questions remain regarding the timing, mechanisms and drivers of these transitions.
Skaergaard is a classic example of a layered intrusion. It is a wonderful natural laboratory for geologists and highly photogenic, with its striking igneous layering. There is near 100% surface exposure as not much grows there; an advantage of its location at 68°N. We have just returned from a six week expedition, studying this fascinating intrusion.
