Survey report 2008/09 summer season Geoscience Australia Authors - Ryan Ruddick and Alex Woods / Geoscience Australia
No full textProgress Code: completedStatement: The survey at Davis used the ITRF2000 at 2000 horizontal datum. Henk Brolsma (AAD Mapping Officer advised that an adjustment of 1.175 metres in a direction of 354 degrees 03' True was needed to bring the data onto the Davis WGS84 datum (as it was in 1996) - the datum on which the Australian Antarctic Data Centre's GIS data for Davis is stored.
Given that Grid North for the UTM zone 43 projection is 2 degrees 46' west of True North in this area, this meant an x shift of -0.004 metres and a y shift of 1.173 metres on the UTM grid.
This shift was not applied to the polygon representing the Library Lounge as Ryan Ruddick advised that this building was surveyed by offsets measured from the Living Quarters and consequently the outline of the Library Lounge was derived from the WGS84 Living Quarters polygon.
The stairways surveyed included two sets adjacent to the Summer Accommodation Module which was not surveyed as it had been surveyed in 2006/07. So after the shift was applied to these stairs an additional small translation was made to align the stair polygons with the Summer Accommodation Module polygon that resulted from the 2006/07 survey.This metadata record details a number of survey reports produced by Geoscience Australia surveyors, during the 2008-2009 Antarctic season.<br/><br/>The available survey reports in pdf format are:<br/><br/>Davis gravity mark<br/>Davis station spatial infrastructure report Larsemann Hills 2009 Macca TGBM Level Survey Tide Gauge Levelling 2009 Vestfold Lake Levelling 2009<br/><br/>Also included is a Summary text file providing further information:<br/><br/>Ryan Ruddick and Alex Woods, Geoscience Australia surveyors, carried out some survey work for Geoscience Australia and the Australian Antarctic Division (AAD) during the 2008/09 summer.<br/> <br/>At Davis and the Vestfold Hills the work included:<br/>1 Installing an absolute gravity benchmark at Davis;<br/>2 A survey mark traverse at Davis and the survey of new buildings;<br/>3 A Davis tide gauge levelling survey;<br/>4 A survey of the Old Wallow for John van den Hoff of the AAD;<br/>5 Measuring relative height differences between lake bench marks and lake water level, for 23 lakes in the Vestfold Hills.<br/><br/>At the Larsemann Hills a GNSS campaign and high precision level survey was conducted across the eastern portion of Broknes.

Survey report 2016/17 summer season, Voyage VMI, Geoscience Australia, Authors - Bart Thomas and Ryan Ruddick
No full textProgress Code: completedStatement: The horizontal datum for this dataset is, as per the survey marks SPM10708, SPM10709 and AUS211RM3, on ITRF2000@2000. Elevations are based on the documented MACQ1982 values for the survey marks from the Australian Antarctic Data Centre Survey Control database. Subsequent levelling connections to the survey network bench marks show that this height datum is consistent with the Mean Sea Level determination of AAE BM1 RM2 in Garden Bay. The survey was preformed using RTK survey method, and checks were made between each of these bench marks.
Typically, the data can be considered accurate to +/- 0.02 metres in the horizontal, and +/- 0.04 metres in the vertical.
Only specific features requested prior to the voyage were measured during this survey, and as such, this dataset is not a complete representation of the area of the survey. Features such as walls, tanks, buildings and associated cut/fill and drainage near these features were not measured at this time.
In areas of tussock and seal wallows, the ground level was taken at the determined natural surface level (i.e. not in the bottom of the wallow, and not on top of the tussock mound). In these areas, solid ground surface may deviate up to as much as +/- 0.5 metres from the measured spot height in the area. The rock outcrops to the north of the Science building were not measured in detail, and are shown in this dataset as only a radius to encompass the feature.
Data from the surveys is available for download in shapefile format. Also available are selected shapefiles which were shifted by the Australian Antarctic Data Centre to the WGS84 horizontal datum on which the station was originally mapped. This was done by applying "The coordinate difference between ITRF 2000 and AUSLIG WGS84 values, based on coordinate values for NMX/1, is -1.40 E and -0.20 N." as given on page 3 of the survey report Macquarie Island OSG Survey Campaign, Voyage 8 Round Trip, March 2002 by John VanderNiet and Nick Bowden. i.e. the eastings of the WGS84 data will be 1.40 metres greater than the ITRF2000@2000 data and the northings of the WGS84 data will be 0.20 metres greater than the ITRF2000@2000 data.Geoscience Australia surveyors Bart Thomas and Ryan Ruddick travelled to Macquarie Island on the Australian Antarctic Division's voyage VMI in November/December 2016.<br/>Survey work for a number of Australian Antarctic projects was undertaken at the station on Macquarie Island.<br/><br/>Project 4092 - Geoscience Australia geodetic and geophysical monitoring program:<br/>- Upgrade and modernise the GNSS equipment.<br/>- Undertake a local monitoring survey of the GNSS equipment.<br/><br/>Project 5067 – Tide Gauges:<br/>- Validate tide gauge reference marks on station and at tide gauge.<br/><br/>Project 5092 – Modernisation and Infrastructure:<br/>- Survey the pits and lights between the ANARESAT dome and the fire hydrant.<br/>- Spot heights along the isthmus.<br/>- Survey the corners of the spa and sauna building and Riometer.<br/><br/>Project 4036 – Remediation of petroleum contaminants in the Antarctic and sub-Antarctic:<br/>- Provide heights on Piezo Tubes
Motherhood Beyond Boundaries: A Philosophical Study of Ashapurna Devi and Sara Ruddick/ মাতৃত্বের নতুন পাঠ : আশাপূর্ণা দেবী ও সারা রুডিকের দার্শনিক ভাবনা
No full text‘Motherhood’ is often seen as something naturally tied to womanhood. I have always found this idea both simple and complicated. In this paper, I try to look at it a bit differently. My discussion moves between two very different writers, one is our Bengali author Ashapurna Devi and the other one is Western feminist thinker Sara Ruddick. As I read their work, I keep noticing how the idea of motherhood changes with context and culture. Feminism, as we know, has long questioned traditional norms and demanded freedom from gender-based injustice. In contrast, Care Ethics, which grew more recently, reminds us that feelings and relationships are also a kind of moral wisdom. Within this space, the idea of motherhood becomes rich and worth thinking about. Ashapurna Devi’s trilogy (Prathom Protishruti, Subarnolata, Bakul katha) always draw me in. As all we know She never called herself a feminist, yet her characters often speak of quiet resistance. Through their daily lives and small choices, they challenge the old rules without even naming it. When I read her, I feel a closeness to the feminist way of thinking, though she never used that word herself. Sara Ruddick, writing from a different world, sees motherhood as a form of thinking, a practice of patience, care, and reflection. Though the two women lived in separate cultures, both see motherhood not as duty alone but as a moral way of being. By putting their ideas side by side, I try to see how feminism, care, and motherhood connect. It is not a fixed concept anymore, it grows and changes with emotion, experience, and time
Survey report 2010/11 summer season Geoscience Australia Authors - Ryan Ruddick, Sam Griffiths and Nicholas Brown / Geoscience
No full textProgress Code: completedStatement: There may be some errors in the report - a corrected version was intended to be archived in the AADC, but this does not appear to have happened. Use cautiously.Executive Summary from the report:<br/>Geoscience Australia's involvement in Antarctica has primarily been focused on the maintenance and enhancement of geodetic infrastructure within the Australian Antarctic Territory (AAT). Such infrastructure provides a fundamental reference frame for the region and supports earth monitoring science applications on both a regional and continental scale. These foundations have furthered the development of geodesy throughout the continent and provided information on the contemporary motion of the Antarctic plate for comparison with long-term geological records. Primary Antarctic geodetic control also contributes to a greater understanding of global earth movement though contribution to the International Terrestrial Reference Frame solutions.<br/><br/>This report focuses on the field work undertaken during the 2010/11 Antarctic summer by Geoscience Australia surveyors at the Davis, Mawson and Macquarie Island research stations, as well as several remote sites in Eastern Antarctica. At each of the research stations, upgrades and local monitoring surveys were performed at the continuously operating reference stations (CORS), which form part of the Australian Regional GNSS Network and also contribute to the International GNSS Service. Remote GPS sites in the Grove Mountains, Bunger Hills, Wilson Bluff and Mt Cresswell were also visited for equipment upgrades and data retrieval. Additional surveys were undertaken directed at enhancing the spatial infrastructure around both the Larsemann and Vestfold Hills. Support was also provided to a number of different Australian Antarctic Division projects.<br/><br/>Surveys of new buildings and other infrastructure at Davis and Mawson were carried out for the Australian Antarctic Division and are described in part 7 of the survey report.<br/><br/>The Related URLs include links to where the following can be downloaded:<br/>1 The survey report;<br/>2 Data from the surveys at Davis and Mawson;<br/>3 GIS data representing features such as buildings at Davis and Mawson.
