This is an animation by Dr Tabitha Pearman and myself, focusing on a submarine canyon on the edge of the European continental shelf. Tides drive large internal waves which interact with the canyon walls, potentially influencing distributions of fauna on the canyon walls (Pearman et al., 2020). This animation is constructed using two hydrodynamic models;…

This animation is actually a couple of different approaches combined to give a very brief introduction to the operation of robotic gliders, before showing an example glider mission between Scotland and Iceland.   I’ve wanted to depict a more realistic glider flight for a while; the problem being that in order to show the nature of…

Work completed as part of a publication (Fraser, N., Inall, M.E., Magaldi,M.G., Haine, T.W.N., Jones, S.C. (2018). Wintertime Fjord-Shelf Interaction and Ice Sheet Melting in Southeast Greenland.Journal of Geophysical Research – Oceans, doi:10.1029/2018JC014435)   Modelled flow in Kangerdlugssuaq Fjord in south-east Greenland.  We found that large internal waves moving into the fjord were important for…

The Navy HECLA project is a continuation of the MASSMO exercises which I have contributed to in the past. It aims to bring underwater and surface autonomous vehicles to an operational level. My role in these exercises is mainly data visualisation, but I’ve also experimented with simple methods for assimilating glider observations into model data.

Exploratory and outreach animations using ROMS model output and simulated glider tracks in the Pemba Channel.  I’ll update when more material is available.

Overview animation of glider movements during MASSMO 4 (Marine Autonomous Systems in Support of Marine Observations) in the Faroe-Shetland Channel in May-June 2017. MASSMO is a pioneering multi-partner series of trials and demonstrator missions that aim to explore the UK seas using a fleet of innovative marine robots. This animation shows some qualitative comparisons between…

A short animation of modelled species response to observed changes in sea surface temperatures between 1960 and 2009, based on the work of Professor Mike Burrows. The grid of points represents ocean species which are initially evenly distributed. As ocean temperature changes, each point is programmed to change its location to attempt to maintain its…

  Some initial experiments working with spherical coordinates which allow you to depict a sphere rather than flattened bathymetry. So far, I’ve managed to get GEBCO bathymetry into Paraview, and warped the surface using the elevation data. Here, the land is warped using true elevation but for the ocean I’ve added a 50x exaggeration so…

Some draft imagery to show progress on the near-real time interpretation of robotic glider data. This example depicts the Navy MASSMO-3 exercise on the Malin Shelf in 2016. Glider data are currently loaded into Paraview in a ‘1 csv per timestep’ form, as it is otherwise hard to get it to recognise timesteps from other…

This is a project that Neil Fraser at SAMS and myself have played with on and off for a while.  Neil created a hydrodynamic model of Kangerdlugssuaq Fjord in south-east Greenland using MITgcm to investigate how local wind events impact the transport of warm water into the fjord as part of his PhD.  While the…

At SAMS, Dr Dmitry Aleynik has developed numerous physical oceanographic models using the FVCOM (Finite-Volume, primitive equation Community Ocean Model) architecture.  Run on a high-performance computer cluster, models such as these allow scientists to perform experiments which would often not be possible in reality.  The example shown here covers the complex inland waters of western…
