Sea Level Rise Modelling

In a Caribbean Small Island Developing State
In 2009, a research project was implemented to study the potential socio-economic impacts of climate change upon coastal communities in Canada and the Caribbean. Grande Riviere in Trinidad and Tobago, one of the study sites, is an important nesting site for leatherback turtles. Turtle watching, part of eco-tourism conducted in that part of the country, is an important source of income for the community. Any significant rise in mean sea level may negatively impact the turtles’ nesting sites and consequently negatively impact Grande Riviere’s socio-economic wellbeing. Hydrographic and topographic surveying techniques and GIS were used to construct spatial models that... (read more)

CUBE Terrain Modelling

Developed by Brian Calder of University New Hampshire, CUBE is a combined terrain modelling, data cleaning and data reduction software for use as a processing tool for high density multi-beam echo sounder data sets. CUBE will estimate the depth at predefined grid node points, making use of all available soundings in the vicinity of the node. The output of the process is a set of depth values at grid node locations, rather than ‘approved soundings’, and performs a radical reduction of the amount of data needed to represent a seabed surface which has been surveyed by a high resolution instrument...

Capturing Convection: Glider Validated Modelling

Can Underwater Gliders Be Used to Check Ocean Forecast Accuracy?
Recently, three unmanned underwater vehicles (UUVs) were deployed in the northwest Mediterranean Sea to monitor open-ocean convection via changes in the local density structure. Mixed-layer depth and thermocline response to buoyancy flux were extrapolated from in-situ profiles and used to infer the occurrence of deepwater formation events. The high-resolution data set acquired has been used to assess ocean forecast model performance in this area. The advantages of employing glider data sets in further validation schemes are discussed here. Forecast models are employed by the oceanographic agencies for meteorological and commercial shipping applications, as well as in naval sonar propagation studies,... (read more)

Fugro Strengthens Metocean Modelling Capabilities

Increased interest in new development areas for oil & gas and renewable energy is resulting in a growing demand for high-quality metocean data relating to these largely unexplored regions. In response, Fugro has strengthened its numerical modelling capabilities. Modelling the complexities of local environmental conditions requires refinement, both in the wind fields driving the models and in the model grid size. Although global models are available, their scale is often too large to capture regional features like tropical cyclones with enough accuracy. Fugro’s newly expanded team of modellers are now working to fill this gap by creating a range of... (read more)

Mapping and Modelling SS Polwell

Originally constructed in the North East of England in 1888, the SS Polwell was used by German forces at the start of World War I. However, early on in the war, the vessel was captured off Gibraltar by the British Admiralty and requisitioned into service as a defensively armed merchant ship. The SS Polwell was torpedoed off the Irish coast by a German submarine in 1918. Now, after resting on the seabed for almost a century, details of this historic shipwreck have been revealed using the latest multibeam sonar technology and CARIS HIPS and SIPS software. On 5 June 1918, the... (read more)

Hydrography for Continental Streamflow Modelling

Water Data Standards Enable New Models and Applications
Land surface hydrography now supports the modelling of continental-scale streamflow at high resolution and in near real time. The US National Hydrography Dataset contains about 2.7 million stream segments averaging 2km in length. This database establishes a national topological network of streams and their drainage areas. The network is now being used in computational models of streamflow that can be run in just 12 minutes for the entire USA, and the approach is also starting to be applied globally. Imagine a continental-scale hydrographic dataset being used for local-scale operational forecasting of streamflow and flooding in near-real-time. This article outlines the surface... (read more)

Bluesky Adds to Flood Risk Modelling Software

The latest aerial photography and detailed earth surface models from Bluesky are being used for demonstration in a software package developed to assess the risk and impact of flooding. To support the launch of ISIS 2D Halcrow has included some GeoPerspectives aerial photography and Digital Terrain Models (DTMs) from Bluesky, to enable users to evaluate the improved modelling functionality.   ISIS 2D is the latest addition to the ISIS by Halcrow suite of products. A fully hydrodynamic computational engine, it is designed to work either as a stand-alone tool or within the ISIS suite of products enabling dynamic integration between... (read more)

3D Modelling Software for Marine Mining

AuruMar, headquartered in South Africa, has purchased Maptek Vulcan 3D modelling software for its marine continental shelf exploration operations. AuruMar will apply Vulcan GeoModeller to the mineral resource development programme for its 26 mining leases offshore of Nome, Alaska. The company wanted to be able to look at and model its geological data in 3D, according to Urban Burger, AuruMar geologist. Vulcan GeoModeller provides a complete set of tools for exploration and mining geologists with functionality for both stratigraphic and non-stratigraphic deposits. AuruMar is a technical services company based in Cape Town, South Africa. It was established in October 2009... (read more)
