Tomographic investigation of turbulence and sediment dynamics

Understanding sediment transport has come a long way since the pioneering works of Shields and Bagnold, nearly a century ago. Yet, the complex mechanisms that drive, at larger scales, the morphological evolution of coastal and estuarine environments remain poorly understood at the ‘noisy’ end of the spectrum. Fundamentally, this is a problem of fluid sediment interaction,… Read More Tomographic investigation of turbulence and sediment dynamics

Keynote lecture by Prof Carl Amos at ‘Turbulence and Interactions in Marine Systems (TURBINTERMARS): Turbulence and Sedimentary Processes’

An international  workshop on turbulence and the resulting sedimentary responses was held in The Abdus Salam International Centre for Theoretical Physics, Trieste, Italy. The meeting spanned three days over 23 – 25 February, 2015 and covered topics that ranged from the coastline to the deep sea. There was a good balance between theoretical modelling of… Read More Keynote lecture by Prof Carl Amos at ‘Turbulence and Interactions in Marine Systems (TURBINTERMARS): Turbulence and Sedimentary Processes’

Fieldwork mapping sea-grasses and sediment sampling for grain trend analysis at Ryde, IoW

Ryde, Isle of Wight boasts one of the largest seagrass meadows in the United Kingdom’s southern region. In order to understand the influence of the seagrass meadow on sediment transport and intertidal flats stability, a two-day fieldwork (18th – 19th March 2015) was conducted. The fieldwork is part of a G&G postgraduate student, Anas Annuar’s… Read More Fieldwork mapping sea-grasses and sediment sampling for grain trend analysis at Ryde, IoW

Deriving shallow water sediment properties from seismic reflection data

A new paper, titled “Deriving shallow-water sediment properties using post-stack acoustic impedance inversion”, has recently been published in the peer-reviewed journal Near Surface Geophysics by Geology and Geophysics Research Fellow, Dr Mark E. Vardy. In the paper, Mark demonstrates a method whereby key physical properties of the sediments that comprise shallow subsurface can be derived… Read More Deriving shallow water sediment properties from seismic reflection data
