GSV Wangaratta South VIMP Vic pot tho ura totg 4band radiometric grid geodetic

This GSV Wangaratta South VIMP Vic pot tho ura totg 4band radiometric grid geodetic is an airborne-derived radiometric Potassium, Thorium and Uranium data over a sun shaded total count radiometric data for the South Wangaratta, Vic, 1996 VIMP Survey (GSV3068). The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of uranium (K), uranium (U) and uranium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This GSV Wangaratta South VIMP Vic pot tho ura totg 4band radiometric grid geodetic has a cell size of 0.0005 degrees (approximately 50m). The data used to produce this grid was acquired in 1996 by the VIC Government, and consisted of 43676 line-kilometres of data at 200m line spacing and 80m terrain clearance. The grid was produced by applying the colours red to the Potassium ground concentration, green to the Thorium concentration and blue to the Uranium concentration. The colours were clipped to a 99% linear scale. These colours were transparent over a shaded Total Count. This clipping will necessarily introduce some artefacts into the ratio grids in areas of very low radioelement concentrations. The 3-band image was superposed on the sun shaded TC grid of the same survey to produce the final image.

Buchanan, NT, 2002 - company5 2 (P1023), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Buchanan, NT, 2002 survey were acquired in 2002 by the NT Government, and consisted of 175073 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Disturbance of Intertidal Sediments: The Response of Bacteria and Foraminifera

Incubation experiments are common in marine experimental studies but the impact on organisms and geochemical parameters is poorly understood. Here, the re-establishment of vertical bacterial and foraminiferal zonation in intertidal sediments was studied after sieving and subsequent incubation of sediment. Living (Rose Bengal stained) foraminifera were counted and redox sensitive elements in the pore water were measured using a voltammetric microelectrode. Bacterial abundances were quantified using phospholipid derived fatty acid (PLFA) methyl esters in the range of C12-C22 released from intact phospholipids.
Foraminifera appeared to be predominantly dependent on the presence of oxygen; they re-migrated to the top oxygenated 3 mm of the sediment within 21 days. Total bacterial abundance did not re-establish to original levels even after 49 days. Total fatty acid concentration increased to a depth of at least 70 mm in the field, but decreased with depth in the sieved sediments of the microcosms. This difference is attributed to macrobenthic activity and physical mixing in the field, causing an increased downward flux of electron acceptors (O2, NO3-, Mn(IV), Fe(III)) which is essential for dissimilatory processes at some centimetres depth. In the experimental microcosms, where macrobenthos was removed by sieving, foraminifera alone were not capable of this sediment mixing. The relative amounts of the individual PLFAs were constant with depth, which indicates that no differentiation with depth of the bacterial population by means of bacterial PLFAs could be established both in the field and in the experimental situation. The artificial disturbance led to a long-term change in the vertical bacterial distribution, which was not re-established during the incubation time of 49 days.
