Dr Mattias Green
BiographyI did my MSc and PhD at the Earth Sciences Centre, Göteborg University in Gothenburg Sweden, for Professor Anders Stigebrandt. The thesis focused on the interaction between inshore areas and the coastal ocean, with special attention to the dynamics of strait flows and how we can use physical oceanography to combat eutrophication. After finishing my PhD I worked as a lecturer and director of undergraduate studies at Göteborg University before moving to Wales for a postdoc position working with John Simpson and Tom Rippeth on the structure of turbulence in shelf seas using Autosub. I was then awarded and advanced NERC Fellow on the effects of sea-level change on the dissipation of tidal energy in the past, present and future and how that may impact on climate.
From 2013 I held a position as senior lecturer, then Reader from 2016, in physical oceanography at School of Ocean Sciences.
Research InterestsMy primary research is on modelling changes in the global and regional tides in the past, present, and future oceans. This includes looking at how the tidal energy is lost and how the subsequent mixing generated by the tides is distributed in the ocean. As an application I investigate how changes of the global tides affect the climate controlling overturning circulation under different scenarios, and how changes in the shelf-sea tides can affect the open ocean tides. I also work with observations and theoretical analysis on ocean turbulence, internal waves, and mixing in shelf seas in order to improve our understanding of how the ocean is mixed, and how we can improve ocean models to better replicate the mixing. One connection of this work is to investigate how the physics control biogeochemical processes, especially primary production at the shelf break, and how these have changed as the tides change over long time-scales. My previous research includes the dynamics of strait flows, especially flow resistance mechanisms and hydraulic controls, and the coupling between strait flows and basin water dynamics in fjords and semi-enclosed seas.
