  • Using Captain Scott's discovery specimens to unlock the past: has Antarctic cyanobacterial diversity changed over the last 100 years?

    Jungblut, Anne D.; Hawes, Ian (Royal Society, 2017)
    Evidence of climate-driven environmental change is increasing in Antarctica, and with it comes concern that this will propagate to impacts on biological communities. Recognition and prediction of change needs to incorporate ...
  • Epibiotic pressure contributes to biofouling invader success

    Leonard, Kaeden; Hewitt, Chad L.; Campbell, Marnie L.; Primo, Campbell; Miller, Steven D. (Nature Publishing Group, 2017)
    Reduced competition is a frequent explanation for the success of many introduced species. In benthic marine biofouling communities, space limitation leads to high rates of overgrowth competition. Some species can utilise ...
  • Development of mechatronic dibbling machine for improving the quality of forestry seedlings

    Duke, Mike; McGuinness, Ben; Kunnemeyer, Rainer (University Politehnica Timisoara, 2016)
    A forestry nursery in Tokoroa, New Zealand grows approximately 3 million Radiata pine seedlings per annum of which about 65% (2 million) are of suitable quality for forestry plantations. The high rejection rate of 35% was ...
  • The differential response of kelp to swell and infragravity wave motion

    Mullarney, Julia C.; Pilditch, Conrad A. (ASLO: Association for the Sciences of Limnology and Oceanography, 2017)
    We present field measurements of the movement of the giant kelp Macrocystis pyrifera under wave forcing. We resolve the depth and frequency-dependent responses along the stipe and find different and counterintuitive patterns ...
  • Extracting the MESA SR4000 Calibrations

    Charleston, Sean A.; Dorrington, Adrian A.; Streeter, Lee; Cree, Michael J. (SPIE, 2015)
    Time-of-flight range imaging cameras are capable of acquiring depth images of a scene. Some algorithms require these cameras to be run in `raw mode', where any calibrations from the off-the-shelf manufacturers are lost. ...
  • An illustration of interdisciplinary science: Small-scale coils for transcranial magnetic stimulation

    Wilson, Marcus T.; Waas, Jake; Tang, Alex; Iyer, Kartik; Rodger, Jenny (2017)
    Transcranial Magnetic Stimulation (TMS) is a commonly used medical technique for influencing the strengths of neural connections in the brain. It is used, for example, for treating major depression. In TMS, an electric ...
  • MRI Safe Electrodes for Spinal Cord Stimulation (SCS)

    Hartung, Dirk; Scott, Jonathan B.; McCabe, Steven Owen; Single, Peter (2017)
    Adding decoy filars and non-therapeutic decoy electrodes to therapeutic filars can divert and dissipate a significant fraction of captured RF energy in a distributed way along the lead. Simulated worst case local SAR values ...
  • Tectonomorphic evolution of Marie Byrd Land - Implications for Cenozoic rifting activity and onset of West Antarctic glaciation

    Spiegel, Cornelia; Lindow, Julia; Kamp, Peter J.J.; Meisel, Ove; Mukasa, Samuel; Lisker, Frank; Kuhn, Gerhard; Gohl, Karsten (Elsevier, 2016)
    The West Antarctic Rift System is one of the largest continental rifts on Earth. Because it is obscured by the West Antarctic Ice Sheet, its evolution is still poorly understood. Here we present the first low-temperature ...
