Unlocking the carbon-capture potential of kelp forests

Cambridge Earth Sciences PhD student Zhenna Azimrayat Andrews visited the Ocean Rainforest Inc.’s (ORI) pilot kelp farm, off the California coast, last summer. The results Zhenna gathered alongside an international team will help her construct model simulations of carbon capture using kelp farms. Zhenna reports on her fieldwork here.

Exploring water flow paths in Nepal

Sitting on the ridge top, looking over the expanse of rice paddies dotted with villages, and views down the valley for miles, it’s easy to be captivated by the rural landscape of Nepal.

We’d come to the Melamchi Valley, a few hours outside Kathmandu, to continue fieldwork exploring spring flow paths and their implications for silicate weathering and carbon drawdown in the Himalayas. Our team included us (Zara and Gio, Part III students), trip leader Ed Tipper, PhD student (now successful Dr) Al Knight and two university students from Kathmandu.

From magma to magnets: a summer of fieldwork in Greenland investigating critical metal behaviour in alkaline intrusions

This summer Carrie Soderman, Owen Weller and Charlie Beard headed to Greenland to investigate how metals critical for green technologies form.

Rare earth elements (REEs) are classed as ‘critical metals’ in modern society, meaning a group of metals and minerals that cannot be easily substituted in technology but whose supply is at risk. In particular, the REEs are a vital part of green energy transition technologies, such as the magnets that go inside motors for wind turbines and electric vehicles. Demand for these elements is therefore expected to increase rapidly in the coming decades.

The deep ocean is closer than you think: scientific research and life at sea

Nick Reynard is a postdoc in the Centre for Climate Repair in Cambridge, working with Ali Mashayek’s research group at the Department of Earth Sciences. Here, Nick recounts his experience of boarding a five-week scientific cruise in search of the deep Antarctic waters that rise in the Madagascar Basin.

Reporting on the inaugural environmental geochemistry field trip to Provence

The Department recently launched its new Part II environmental geochemistry field projects as an alternative to the successful and long-standing mapping projects.

According to Ed Tipper, co-director of undergraduate teaching, “The decision reflects the diverse research areas of our teaching staff, combined with a growing student interest in pressing environmental issues. This year, 13 students enrolled in the new type of project, making it viable to develop a new field trip to train students ready for this environmental pathway.”

The following blog post is written by Tom Marquand, PhD student in the Department and demonstrator on the inaugural environmental geochemistry field trip to Provence, France.

Exploring the environments inhabited by Earth’s earliest animals in Namibia

Fossils of the Earth’s earliest animals appear abruptly in the geological record ~574 million years ago (Mya), and then suffer a mysterious decline in diversity just a few million years later ~550 Mya. Some researchers consider this biological change to be Earth’s first mass extinction event.
