Jan Lieser, Robert Massom & Petra Heil
The sea-ice reports compiled in this document are weekly reports on sea-ice conditions for East Antarctica, including sub-weekly updates. They were prepared to support ship operations in East Antarctica during the 2015/2016 shipping season. These reports were primarily used to inform the Australian Antarctic program, but were partly provided to other Antarctic operators as well.

Idiosyncratic concepts in the music of Henry Threadgill's Zooid : an applied investigation into compositional and improvisational techniques

GK Hill
The purpose of this research is to investigate the music of Henry Threadgill’s Zooid, focusing on compositional and improvisational techniques, and how these function in an ensemble setting. Discoveries from this research will be used to advance the author’s creative practice; a folio of original compositions and performance recordings exploring Threadgill’s ideas will be included in this project. Henry Threadgill has stated in recent interviews that he has developed an intervalbased harmonic system and a...

Evaluating the extinction risk of the endangered Maugean skate (Zearaja maugeana), Macquarie Harbour, Tasmania

K Weltz
Rare species, with low population sizes, restricted ranges and specialized habitat requirements, are particularly vulnerable to extinction. A small population generally has a low genetic effective population size (Ne) and can be susceptible to genetic effects (i.e. genetic drift and inbreeding), resulting in the loss of population fitness and a reduced evolutionary potential to adapt to changes occurring in the environment. Species that have a restricted range generally have less ecological flexibility, resulting in highly...

Mixing (MX) Oceanographic Toolbox for EM-APEX* float data applying shear-strain finescale parameterization

Amelie Meyer, HE Phillips, BM Sloyan & KL Polzin
The Mixing Oceanographic Toolbox provides a framework to estimate the dissipation rate and diffusivity from Electromagnetic Autonomous Profiling Explorer (EM-APEX) float observational data. The EM-APEX floats measure the temperature, salinity, pressure, and horizontal velocity of the current. Vertical gradients of velocity and buoyancy are estimated and a finescale parameterization is applied. This method provides order of magnitude estimates of mixing as well as estimates of the regional variability of mixing

Numerical calculation of manoeuvring coefficients for modelling the effect of submarine motion near the surface

CD Polis
Given the significant amount of time modern submarines conduct operations near the surface of the ocean, there is significant value in the capacity to predict the behaviour of a submarine operating in the near surface region. During most near surface operations, the primary forces involved are due to transient ocean waves and are statistical in nature. Yet there is also a contribution from the motion of the submarine near the surface, which has received less...

Native and invasive mammalian carnivores in a forestry and agricultural landscape in northwest Tasmania

JM Lyall
Globally, human activities including land clearing, habitat conversion and degradation, and human induced climate change are putting immense pressures on biodiversity. Habitat change is a primary cause of species decline and extinction, but in many places invasive predators, often favoured by habitat change, also have had large impacts on biodiversity through direct predation, competition and disease transmission. In the Australian island State of Tasmania, a higher percentage of the original forest cover has been maintained...

Seagrass Presence Absence NSW (ACEAS)

Robert Canto, James Udy, Kathryn McMahon, Michelle Waycott, Kieryn Kilminster, Gary Kendrick, Chris Roelfsema, Peter Scanes & Greg West
This seagrass habitat map was produced by the ACEAS Seagrass working group as part of the seagrass habitat risk modelling effort. The map identified seagrass presence based on 1) on the NISB (National Intertidal-Subtidal Benthic) Habitat Map created by the University of Tasmania for a partnership between the Department of Climate Change and the National Land and Water Resources Audit, 2) UNEP WCMC Seagrass map 2005, 3) publications/reports and 4) expert knowledge/personal observation.

Markov models for the evolution of duplicate genes, and microsatellites

TL Stark
Duplicate genes and microsatellites are two key sequences in the study of evolutionary genomics. Gene duplication has been identified as a central process driving functional change in genomes, since it creates functional redundancy in the genome and allows for subsequent mutation to occur in the absence of selective pressure. Microsatellites are rapidly evolving sequences which can be studied over much smaller timescales than most other sequences, and are thus key to the study of population...

Agency in garden imagery : a painterly investigation into thresholds of otherness

PL Burnett
This studio-based investigation explores traditional representations of gardens in order to create an alternative way of perceiving cultivated space. This thesis presents a way of perceiving “otherness” in garden imagery through the materiality, colour and agency of paint. The works offer an alternative visual conception of tensions between gender, identity, power, agency and authority. The studio practice examines pictorial devices of the imperial vista, diagrammatical mapping, encompassing narrative, framing portals, surfaces tension and compositional axis....

Tectonic, Oceanographic, and Climatic Controls on the Cretaceous-Cenozoic Sedimentary Record of the Australian-Antarctic Basin

Isabel Sauermilch
Understanding the patterns and characteristics of sedimentary deposits on the conjugate Australian-Antarctic margins is critical to reveal the Mesozoic to present tectonic, oceanographic and climatic conditions in the Australian-Antarctic Basin. However, unravelling its evolution has remained difficult due to the different seismic stratigraphic interpretations on each margin and sparse drill sites. Here, for the first time, we collate all available seismic reflection profiles on both conjugate margins and develop a consistent seismic stratigraphic framework across...

Compete© An individual-based spatial modelling software to simulate ecological interactions and evolution in sessile organisms

Craig Johnson
Compete © is a spatial individual-based modelling package facilitating study of population and community dynamics and evolution in assemblages of sessile modular organisms competing for space. The kernel of its operation is a probabilistic cellular automaton, but with additional functions for recruitment, mortality, dispersal and disturbance. The model uses synchronous updating of the landscape.

Frontotemporal dementia and amyotrophic lateral sclerosis proteins in neurite health and dysfunction

RAK Atkinson
A number of proteins have been identified which are pathologically and/or genetically associated with both frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). A hexanucleotide repeat expansion in the non-coding region of the C9ORF72 gene is the largest genetic factor associated with FTD and ALS. Additionally, pathological inclusions of the TDP-43 protein are found in brains of approximately 50% of FTD cases and 90% of ALS cases. However, the normal function of these two proteins...

Adaptive control solutions for advanced unmanned underwater vehicle applications

CD Makavita
Unmanned Underwater Vehicles (UUVs) have evolved from rudimentary Remotely Operated Vehicles (ROVs) with operator control of the actuator outputs directly to sophisticated ROVs and Autonomous Underwater Vehicles (AUVs) with semi and fully autonomous control systems that require minimal to zero operator input. In addition, the rapid progress in technology has made UUVs to evolve from the mammoth work- class ROVs to mini and micro ROVs and AUVs. With these changes in UUVs there has been...

Transplanted kelp reefs at Maria Island, TAS, Australia

Cayne Layton, Craig Johnson, Jeffrey Wright, Matthew Cameron, Victor Shelamoff & Masayuk Tatsumi
Data accompanying Layton et al. 2019, Resilience and stability of kelp forests: the importance of patch dynamics and environment-engineer feedbacks. PLOS ONE. To explore how resilience and stability of kelp habitats is influenced by this habitat degradation, we created an array of patch reefs of various sizes and supporting adult Ecklonia radiata kelp transplanted at different densities. This enabled testing of how sub-canopy abiotic conditions change with reductions in patch size and adult kelp density,...

From climate change to climate action to climate justice : an ecological neo-Gramscian analysis of ecosocialism’s potential

EM Croeser
The world confronts an interlinked ecological, economic, social, and political crisis crystallised in the issue of climate change. The failure of governments acting alone and through international institutions to effectively address the climate crisis has led to the growth of a distinct climate movement within civil society whose broad aim is to bring about the changes required to mitigate anthropogenic global warming. This dissertation examines the role that ecosocialists are playing within the broader climate...
