Large lakes tend to be thermally stratified, with a layer of relatively warm water near the surface, and a deeper layer of colder water underneath. The temperature of the surface water fluctuates over the year, while the temperature of the deeper water remains more stable: hence, the thermal stratification is strongest during the summer, when
During the second part of today’s seminar, MPhil student James Sear presented the results of his new experiments on turbulent plumes in a cross-flow. During the last few months, James has been studying what happens when a steady flux of contaminants are released into a river: the contaminants are transported by the current, while being
The coastal ocean is a highly dynamic and vital biogeochemical mediator between land and sea. Coastal waters frequently experience poor water quality: this is partly due to submarine groundwater discharges, in which polluted water is released at the bottom of the ocean. These discharges are relatively poorly understood, and research is ongoing to characterise them.
The future of floating Antarctic ice shelves is one of the principal uncertainties surrounding projections of future sea level rise. Melting of Antarctic ice shelves is caused by relatively warm and salty Circumpolar Deep Water currents upwelling from the ocean depth. A recent article co-authored by Dr Ali Mashayek classifies near-shelf water masses using an
On Thursday 28 December we hosted ‘A Symposium on Energy & Environmental Flows’ to celebrate Professor Andy Woods’ 60th birthday. It was a wonderful event, with a packed schedule of talks throughout the day on topics from volcanic eruptions, ocean circulation, glaciology, and carbon dioxide removal technologies, to ‘how to stop your Granny catching fire’!
