  • the community funding agency and the voluntary sector purchase of service contracting in otago Southland
    Australian Journal of Public Administration, 2004
    Co-Authors: Debiprosad Majumdar
    Abstract:

    The purpose of this article is to study the efficacy and deficiency of purchase of service contracting in helping the voluntary organisations in the Otago/Southland region in New Zealand and the Community Funding Agency (now defunct) achieve a set of specific objectives. The findings are based on the information collected from (a) the responses of 57 participating voluntary organisations to the questionnaire mailed to them, and (b) face-to-face, open-ended interviews with 28 voluntary sector managers, the three outreach workers operating in the Otago/Southland area at the time of writing and eight people formerly associated with the Community Funding Agency at senior management level. The data obtained through field research are verified with prevailing literature–local as well as international.

  • Remote Topographic Forcing of a Baroclinic Western Boundary Current: An Explanation for the Southland Current and the Pathway of the Subtropical Front East of New Zealand*
    Journal of Physical Oceanography, 2002
    Co-Authors: Charles E. Tilburg, Harley E. Hurlburt, James J. O'brien, Jay F. Shriver
    Abstract:

    The Southland Current is a western boundary current adjacent to the South Island of New Zealand and flows along a segment of the Southern Hemisphere subtropical front (STF). The physical mechanisms that govern the behavior of this current and other portions of the STF and subantarctic front (SAF) are investigated using one regional and three global ocean simulations. The three global ocean simulations used in this study are a 1 ‰layer reduced-gravity linear simulation, a six-layer nonlinear flat-bottom simulation, and a six-layer nonlinear simulation that incorporates vertically compressed, but otherwise realistic, bottom topography confined to the abyssal layer. All three simulations have horizontal spacings of ?8 and are forced with climatological-mean monthly wind stress data. The regional simulation has a horizontal spacing of ‰8 and contains two layers, with an idealized bottom topography. The only forcing is supplied by inflow and outflow ports. The pathway of the SAF is shown to be strongly influenced by a barotropic response of the associated flow to bottom topography. Currents associated with the SAF flow along the southern edge of the Campbell Plateau, a large submarine platform southeast of New Zealand. In contrast, the location of the Southland Current and the pathway of the STF east of New Zealand are due to remote forcing of upper-ocean currents by topographically constrained abyssal currents. Whereas most western boundary currents can be described as responses of the ocean to interior Sverdrup flow with some modification, analysis of the numerical simulations within this study shows that the Southland Current is due to a completely different formation mechanism. The presence of the Southland Current and the STF east of New Zealand are instead due to a combination of northward topographic steering of surfacelayer thickness gradients approximately 128 east of New Zealand and westward propagation of these perturbed gradients. A portion of the abyssal flow associated with the SAF is shown to form a topographically constrained deep western boundary current (DWBC). This DWBC follows the edge of the Campbell Plateau, eventually flowing generally northward. When the surface zonal flow associated with the STF southeast of New Zealand encounters this meridional abyssal flow, it is advected northward, creating an imbalance in the potential vorticity within the flow. In an attempt to conserve potential vorticity, the perturbed surface-layer thickness gradients propagate westward until they encounter New Zealand’s South Island, at which point they form the observed Southland Current. Transport associated with the STF thus flows northward along South Island, eastward along the Chatham Rise, and southward once east of the rise. This formation mechanism and the downstream behavior of the STF are illustrated in a simplified regional simulation that reproduces the pathway of the STF and the location of the western boundary current extremely well.

  • Evolution of the Winton Basin, Southland
    New Zealand Journal of Geology and Geophysics, 1995
    Co-Authors: J. P. Cahill
    Abstract:

    Abstract The Winton Basin is one of three Cenozoic sedimentary basins preserved in the onshore Southland region of New Zealand. Seismic reflection and petroleum well data have been analysed to reveal the stratigraphy and structural evolution of the basin. The oldest known strata in this basin are late Eocene terrestrial shales, sandstones, and lignites deposited in half grabens that formed as a result of oblique extension. Mid‐outer shelf to upper bathyal niudstones were deposited over a wide area during a marine transgression in the Oligocene. Shallowing of the basin and tectonic quiescence led to limestone deposition in the early Miocene. Later, regional tilting resulted in uplift in the north and east and deposition of terrestrial lignites and gravels across the basin and the basement high to the south. Understanding the evolution of the Winton Basin provides an important link between western Southland and the Clutha region, constraining the timing and style of regional tectonic events.

  • provenance of permian triassic volcaniclastic sedimentary terranes in new zealand evidence from their radiogenic isotope characteristics and detrital mineral age patterns
    New Zealand Journal of Geology and Geophysics, 2002
    Co-Authors: C J Adams, Mark Barley, Roland Maas, M G Doyle
    Abstract:

    Abstract Detrital mineral age patterns, Rb‐Sr age, and initial strontium isotope ratio variations are reported for metasediments of the Brook Street, Dun Mountain‐Maitai, and Murihiku Terranes (informally grouped as “central arc terranes") of New Zealand. U‐Pb SHRIMP detrital zircon age populations in Late Permian Tramway Formation, sandstones of the Dun Mountain‐Maitai Terrane in Nelson and Southland, New Zealand, show restricted Late Permian (253–268 Ma) and broader Devonian‐Carboniferous (330–373 Ma) age components in about equal proportions, with a minor (<20%) proportion of early Paleozoic and Mesoproterozoic ages. The Permian component is related to contemporaneous volcanic inputs, whereas the older Devonian‐Carboniferous component is derived from a mixture of exhumed continental crust of Lachlan Fold Belt, and possibly New England Fold Belt age characteristics. A detrital zircon age population of Jurassic Barretts Formation sandstone of the Brook Street Terrane in Wairaki valley, Southland, carries...
