Sediment in the deep ocean. Part 2: thermohaline currents that shape the seafloor

In Part 1 we differentiated between (1) shallow-marine tide-related currents from (2) purely gravitational sediment-laden currents. We could add that the former are periodic, as they are controlled by the effect of the Moon and Sun gravitational fields on the oceanic water as the Earth revolves, while the latter are sort of ‘spontaneous’ currents driven by the Earth gravitation field on sedi ...[Read More]

Congo Canyon: A Chat with Dr Steve Simmons

It is always an interesting period when the time comes around for me to write my blog for the SSP page. My research is predominantly in numerical modelling, which would be interesting if I was modelling awesome natural phenomena, but I don’t. I general assess the sensitivities of the numerical models to different sorts of uncertainty and whilst this is important work for understanding the outputs ...[Read More]
