DAS seismic monitoring of the shallow CO2 controlled-release experiment at the South West Hub In-Situ Laboratory

Borobudur temple has been famously known as one of the Indonesian heritage masterpiece. Various aspects of it had been studied thoroughly since the beginning of 20th century A.D. Those studies tended to be monumental centric, giving less attention to the cultural context of the temple and its surroundings. Settlement in the nearby places is one of the topics which not have been studied much yet; leaving a big question about how the settlement supported continuity of many activities in the temple, or even the other way around; how the temple affected the settlement. There is only a few data about old settlement found in situ in Borobudur site, only abundance of pottery sherds. The analysis applied on to the potteries find during the 2012 excavation had given some information about the old settlement in Borobodur site. The old settlement predicted as resided in the south west area, in the back side of the monument.

Host Relationships

The mistletoe flora of southern Western Australia was studied over a 30-year period with a particular emphasis on distributions, host relationships and fire. The study area encompassed Western Australia south of ~26° S. It included all the South-west Botanical Province and southern components of the Eremaean Botanical Province, with the northern boundary corresponding with bioregional boundaries. Vegetation ranges from wet and dry sclerophyll forest through woodlands and heaths to deserts. The mistletoe flora comprises 21 taxa, 19 in the Loranthaceae and two in the Santalaceae. They infect 153 species in 25 genera and 15 families. The Fabaceae provides hosts to more taxa than any other family; however, the genus with most host species, Eucalyptus (Myrtaceae), supports only two mistletoe species, one of which barely enters the study area. Melaleuca (also Myrtaceae) is host to seven species. The number of mistletoe species per bioregion ranges from 0 to 18, with 12 species in the seven bioregions of the South-west Botanical Province and 20 in the six bioregions of Eremaean Botanical Province that are within the study area. In both provinces, diversity is lower in coastal areas and higher in more arid, inland areas. Most mistletoe habitats in the study area are fire-prone. One species is probably capable of resprouting whereas all other taxa are obligate seeders. With no means of in situ seed storage, post-fire recovery depends on seed importation. Fire is the most pervasive (but not the only) threatening process operating today. However, fire management in more populous agricultural and urban areas safeguards many populations in the South-west Province.

Mobile Condition

Abstract. Ethane can be used as a tracer gas to distinguish methane sources, both at the local and global scale. Currently, ethane can be successfully measured using flasks or dedicated in-situ analyzers. In our study, we consider the possibility of using the CRDS Picarro G2201-i instrument, dedicated to isotopic CH4 and CO2, for suitable measurements of ethane:methane ratio in mobile field, near-source conditions. Our work was divided into three steps. First, laboratory tests were run to characterize the instrument in stationary conditions. Then the instrument performance was tested in the field, as part of a controlled release experiment and finally during mobile measurements focused on gas compressor stations. The results from the field are compared with the results from other instruments, dedicated to ethane measurements. Our study clearly shows the potential of using the CRDS G2201-i instrument to determine the ethane:methane ratio in methane plumes in mobile condition with an ethane uncertainty of 50 ppb. Assuming typical ethane to methane ratio ranging between 0 and 0.1 ppb ppb−1 we conclude that the instrument can correctly estimate the “true” ethane to methane ratio within 1-sigma uncertainty in CH4 enhancements of 1 ppm or more as can be found in the vicinity of strongly emitting sites (such as natural gas compressor station).

AbstractWater shortages have led the Libyan authorities to investigate and then develop fossil water resources in the remote south of the country. Initially the development was in situ, but in 1979 it was decided to embark on an ambitious water carrier to bring water from the south-east and the south-west of the country to the settled areas of the northern coast. It is concluded in the paper that Libya will have developed sufficient water by the end of the century to secure its urban and industrial needs. It will also have the option to allocate a similar, or an even greater, quantity to agriculture than at present achieved, but it is argued that such agricultural allocations will not be economically viable.

The Subject

Through the kindness of Dr. Flett there has come into my hands an interesting boulder of nepheline-syenite belonging to Sir John Murray, dredged during the expedition of the Michael Sars(1) from the Atlantic Rise at a depth of 1,750 fathoms at a place about 150 miles south-west of the south-western corner of Ireland (Station 95 of the Reports of the Michael Sars Expedition). The slices examined were slides Nos. F 2092 to F 2095 from the Geological Survey Collection and two belonging to Dr. Peach. It is a boulder of remarkable freshness, and so entirely unlike any other specimen as yet recorded from the floor of the Atlantic that the question of its origin is of some interest. The fact that no other fragments of the same type were obtained in this dredging militates against the view that it is part of a mass in situ on the sea-bottom. Its companions from the same station, and in fact all the specimens collected by the Michael Sars, have been recognized by Dr. Peach and Dr. Flett as similar to rocks occurring commonly in Ireland, the North-West Highlands, and the Southern Uplands of Scotland, and not one among them is closely related to the nepheline-syenite. Bocks of Irish types have also been described by Professor Cole and Mr. Crook (2) as a result of earlier dredgings of the Atlantic floor, and again no specimen has been found remotely resembling the subject of this paper.

A method has been suggested for geotechnical monitoring of tectonic fault rock mass of the south-west wall in Qajaran open-pit mine by applying the pseudo-static method of CPTu (Cone Penetration Test with in-situ pore water pressure measurements) which gives an opportunity to define the root parameters of soils such as: pore water pressure, unit weight, drained and undrained shear strength. The versatile in-situ CPTu methods allow to profile simultaneously the geotechnical properties of each soil strata with permanent penetrating speed, and also while using the SCPTu (Seismic Cone Penetration Test with in-situ pore water pressure measurements) method, as well as determine horizontal and shear seismic wave velocities from the given geomechanical environment. At that, it also becomes possible to pull out independently intact samples from tectonic-fault-soils for future laboratory testing. Two different approaches for geomechanical proposition of the south-west wall stability of Qajaran open-pit mine based on the limit equilibrium theory and outputs from the proposed in-situ geotechnical seismic monitoring (SCPTu) have been analysed. The difference of the results from the two analyzed approaches (USA vs ESA) was about 8 to 10% in estimating the slope stability. Based on the analyzed results of the stability of the south-west wall of Qajaran open-pit mine, it is recommended to apply undrained strength analysis for undrained tectonic-fault soils (USA – Undrained Strength Analysis) instead of the effective drained strength analysis (ESA – Effective Strength Analysis) for drained rocks by taking into account the developed excess pore water pressure when saturated clayey soils sheared in undrained conditions.

Two Sides

Basic Structure: A broad flight of twenty-one steps leads up from the south-west angle of the Temple of Apollo to a partially paved court immediately in front of the lower face of the scarp. This is given a quadrilateral delimitation by the angular revetment of an irregularity in the scarp to the west, and by the monumental water tank to the east of the entrance to the grotto. The entrance was hewn in the cliff face in the form of three arches (now much destroyed), and was revetted with large well-draughted limestone blocks. Of these, only the lower two courses are now in situ, but individual blocks of the upper courses have been collected and amongst them are those with crowning mouldings and one bearing the fragment of a Greek inscription (height:of letters, 25 cm. approximately).The interior of the grotto consists basically of a central oblong depression, paved and cemented, surrounded on the two sides and the back by a raised staging—thus giving rise to the term of reference ‘TRICLINIUM’—while between the staging and the walls are the tanks and channels: associated with the water supply and drainage.Considered longitudinally, the interior may be divided into three entities. The first extends from the entrance to a pair of rock-hewn columns bearing rude inscriptions. Immediately above this compartment lay the terrace of an ancient rock-cut path and its collapse has breached the path and totally unroofed this section of the grotto.
