A Review of Spatial Interpolation Methods for Environmental Scientists

This review aims to provide some guidelines and suggestions in relation to the application of the methods to environmental data by comparing the features of the commonly applied methods that fall into three categories, namely: non-geostatistical interpolators, geostatistical interpolators and combined methods. Commonly used assessment measures are summarised and the criteria used to judge each measurement are also discussed. Two new measurements are proposed and a procedure is developed to compare the performance of the methods for different variables and from various disciplines. A total of 51 comparative studies on the performance of various methods in environmental sciences are summarised. The performance of 62 methods and sub-methods in the 51 comparative studies is compared. Several factors that affect the performance are discussed, including sampling design, sample spatial distribution, data quality, correlation between primary and secondary variable, and interaction among various factors. The impacts of sample density, variation in the data, sampling design and stratification on the estimations of the methods are quantified using data from 77 cases. A total of 26 methods are then classified based on their features to provide an overview of relationships among these methods. These features are quantified and a cluster analysis is conducted to show similarities among these spatial interpolators. A decision tree for selecting an appropriate method from these 26 methods is developed based on data availability and nature. Finally, a list of software packages for spatial interpolation is provided. Some important factors for spatial interpolation in marine environmental science are discussed, and recommendations are made for applying the methods to marine environmental data.

A Framework for Modelling Shoreline Response to Clustered Storm Events: Case Studies from Southeast Australia

Coastal communities in Australia are particularly exposed to coincident natural hazards, whereby tropical cyclones and extra-tropical storms cause damage to infrastructure and shorelines from severe wind, flood and storm surge. Because the climatic drivers of severe storms are stronger under certain conditions (e.g. during La Ni±a periods for tropical cyclones), these events can repeatedly impact the coast over periods of weeks to months. Historically, major episodes of beach erosion along southeast Australia have occurred during every decade over the last century, with the most severe in 1974 resulting from two extra-tropical storms in two months. 

While the process of beach erosion is well understood in general terms, the response of a specific sector of coast to clustered storms may not be. For effective coastal management, this site specific knowledge becomes essential. Here we present a framework for integrating coastal geomorphology and coastal engineering approaches to model shoreline response to clustered storms at a spatial scale that can directly inform management agencies. We focus on two case study areas in southeast Australia, the beaches of the Adelaide metropolitan coast (South Australia) and Old Bar beach (central New South Wales) where erosion is a management priority. 

For each site we adopt the coastal sediment compartment as the functional management unit, mapped for the Australian continent at multiple spatial scales, and use sub-surface information (boreholes, ground penetrating radar profiles) to estimate sediment volumes in the upper beach to foredune. These data are then used to inform shoreline response modelling linked to an event time series (observed and hind cast) as a separate project component. Future work includes assessment of `at-risk infrastructure at each site. This paper is a contribution to the Bushfire and Natural Hazard Cooperative Research Centre project Storm surge: Resilience to clustered disaster events on the coast.

Marine Seismic Surveys Shape files and Kml files

Geoscience Australia has been updating its collection of navigation for marine seismic surveys in Australia. These include original navigation files, the 2003 SNIP navigation files and digitised survey track maps. The result will be an updated cleansed navigation collection.

The collection is based on the SNIP format P190 navigation file which follows the UKOOA standard. Industry standard metadata associated with a seismic survey is preserved.

To assist industry, Geoscience Australia is making available its updated version of cleansed navigation. Although the process of updating the navigation data is ongoing and there is still legacy data to check, the navigation data is at a point where a significant improvement has been achieved and it is now usable. Users should be aware that this navigation is not final and there may be errors. Geoscience Australia (email - AusGeodata@ga.gov.au) appreciates being notified of any errors found.

The data is available in both KML and Shape file formats.

The KML file can be viewed using a range of applications including Google Earth, NASA WorldWind, ESRI ArcGIS Explorer, Adobe PhotoShop, AutoCAD3D or any other earth browser (geobrowser) that accepts KML formatted data.

Alternatively the Shape files can be downloaded and viewed using any application that supports shape files.

Data from the Deep:  New Geological Results from Geoscience Australia's Marine Survey of Frontier Basins, Southwest Australian Margin

Under the Australian Government's Offshore Energy Security Program, Geoscience Australia conducted a marine reconnaissance survey (GA2476) from October 2008 to January 2009 using the German research vessel RV Sonne.  The 90-day survey acquired geological and geophysical data over poorly known areas of the Zeewyck and Houtman sub-basins (Perth Basin), the southern Exmouth Sub-basin and Bernier Platform (southern parts of the Carnarvon Basin) and the Cuvier Plateau (also referred to as the Wallaby Plateau).  Over the duration of the survey, a total of 229 000 square kilometres of multi-beam sonar data and almost 25 000 line kilometres of gravity, magnetic and sub-bottom profiler data was collected.   Geological targets were identified using a combination of pre-existing seismic lines, concurrently acquired seismic lines (Geoscience Australia survey 310) and simultaneously acquired swath bathymetry, sub-bottom profiler records and camera tows.  In general, submarine canyons provided the best opportunity for sampling the pre-breakup sedimentary strata as they were deeply incised and had steep slopes. Other steep slopes were identified in scarps, ridges and peak features.  Sites were selected mainly to recover rocks from the pre-breakup succession (Valanginian and older) in order to determine the synrift sedimentary rocks and to identify any potential source rocks.  A number of dredges were also acquired to sample the post-breakup succession and peak features that were potentially volcanic.  Thirty stations operating in water depths from 1,000 to 5,000 metres recovered rocks.  Rock types, age constraints, depositional environments and geochemistry results from the rock samples have been tied into the tectonostratigraphic framework for the frontier depocentres (identified in GA's new s310 seismic data and vintage seismic data).  The insight gained has helped assess the potential petroleum system elements for these frontier depocentres and will feed into petroleum system modelling.

Proterozoic microfossils from the Roper Group, Northern Territory, Australia

The Roper Group (minimum age approximately 1300 x 10^6yr) is a shallow water sequence of sandstone, siltstone, and shale, with minor, sub-economic oolitic ironstone. The depositional environments of the Group as a whole, range from fluvial, through deltaic or estuarine, to marine, and a number of different environments of deposition for the ironstones can be recognised. Shales from the McMinn Formation at the top of the Group have yielded an assemblage of microfossils. The microbiota includes algal cells and filaments, large acritarchs and giant filaments of uncertain affinity. A probable life cycle and an example of endospory may indicate that some of the organisms are eukaryotic. The flora is very advanced for its geological age, but this is probably because most other Precambrian microbiotas come from carbonate, stromatolitic environments, where simpler and more conservative forms would have pre-dominated. The microfossils are in a particularly good state of preservation because of the low degree of thermal metamorphism which the sediments have undergone. Geochemical and petrographic studies of the organic matter indicate that its composition and level of organic maturation are appropriate for the generation of oil. The rank of the organic matter is locally increased by proximity to dolerite sills which intrude the Group as a whole.

Australian petroleum accumulations report. Canning Basin, Western Australia

As at January 1993, nineteen hydrocarbon accumulations, six of which are commercial, have been discovered in the Canning Basin. The commercial accumulations occur in Permian to Devonian reservoirs on an area of relatively shallow basement (Lennard Shelf) flanking the northern margin of the Fitzroy Trough. Oil is produced from Famennian reefs, associated drape structures, and four-way dip closures in Permo-carboniferous, Grant Group and Anderson Formation sandstones. The most likely sources of these hydrocarbons are Late Devonian and Carboniferous marine shales in the Fitzroy Trough kitchen area. 

The small size of the accumulations in the Canning basin (less than 0.5 million barrels of recoverable oil) precludes the development of large infrastructure projects. Oil is trucked to the storage and shiploading facilities at Broome and then shipped to the Kwinana oil refinery in Western Australia.

On the southern margin of the Fitzroy Trough, oil and gas have been recovered from a transgressive Ordovician sequence of sandstones shales and carbonates. Although the Ordovician has yet to yield a commercial discovery, Devonian reef plays in the overlying section may enhance the attractiveness of Ordovician objectives in this area.

To date, exploration effort in the basin has been largely directed to the northern, onshore Canning Basin. The offshore Canning and the Kidson Sub-basin remain underexplored.  Higher risk plays in these areas have yet to be adequately tested.
