title: Parkes observations for project P427 semester 2015APRS

description: Timing of the dozen pulsars discovered in six globular clusters by us in the framework of P303 and timed in the context of P427 has ensured high quality results, which have been reported in several papers, three more of which are in preparation.  We now propose to continue our timing project, performing a small number of visits to the six globular clusters, in order to measure higher order derivatives of the rotational and/or of the orbital parameters of the pulsars and to safely keep coherence in the timing solutions. With a very limited investment of additional telescope time, that will enable studying some poorly constrained aspects of the inner dynamics of the observed globular clusters, as well as providing the ephemeris for the best possible searches for gamma-ray and/or gravitational wave emission from the targeted pulsars.

title: Parkes observations for project P887 semester 2015APRS

description: Searches for radio pulsations from Fermi sources have been astonishingly fruitful, both in discovering new pulsars and in probing the physics of high-energy emission.  We propose observations of members of two promising Fermi source classes: (1) candidate enshrouded millisecond pulsars (2) new "blind search" gamma-ray pulsars.  The former are fascinating systems in which the wind of an energetic recycled millisecond pulsar is disintegrating its companion; detecting pulsations turns them into laboratories for this process.  The latter are pulsars recently discovered in computational tour de force trawls of the Fermi data.  Radio pulsations greatly add to the information we can obtain; conversely, deep upper limits constrain emission models.

title: WAMSI 2 - Dredging Science Node - Project 5.3 - Natural Dynamics

description: The Theme 5.3 study was undertaken to improve our understanding of the spatial and temporal patterns in seagrass composition, abundance and reproductive phenology in the Pilbara region. Key environmental parameters, especially light, that influence seagrass survival and can be altered by dredging were also characterised.

From August 2013 to March 2015 (18 months), surveys of seagrass abundance were undertaken in the Exmouth Gulf region. The locations surveyed (South Muiron Island, Bundegi and Exmouth Gulf) encompassed a range in water clarity from clear to turbid. Less frequent surveys were undertaken at other locations in the Pilbara: Thevenard Island, Rosemary Island and Balla. Measurements of seagrass abundance were also obtained from monitoring conducted as part of the dredging and dredge-spoil management plan for Chevron Australia’s Wheatstone Liquefied Natural Gas (LNG) Project.

During each survey measurements were made in the field, photographs were taken or samples were collected in order to measure the following variables:
1.	percentage cover of seagrass and other benthos;
2.	above- and below-ground biomass, shoot density, leaf length, leaf width and number of flowers;
3.	density of seagrass seeds;
4.	sediment grain size;
5.	stable isotope ratios (13C and 15N) of seagrass leaf tissue; and
6.	water quality (light, conductivity, temperature, salinity, nutrients, suspended particulate matter and chlorophyll).

title: WAMSI Dredging Science Node: Theme 5 Project 5.4 Recovery mechanisms

description: The objective of Project 5.4 was to determine whether recovery of seagrass in the Pilbara following disturbance is by sexual (recruitment from seeds) or asexual (vegetative regrowth from rhizome extension) means, and the relative importance of each, thereby determining the capacity, timeframes and mechanisms of recovery from light and sediment deposition effects. This was achieved through an experiment in which plots cleared of seagrass were enclosed by a barrier or left open, and changes in cover were compared to unmanipulated control (and procedural control) plots. The experiment was done at two sites, a 2-m deep (the 'shallow' site) and a 6-m deep (the 'deep' site). The experiment was intended to run for 6 months, but after 5 months disturbance caused by Tropical Cyclone (TC) Olwyn reduced seagrass cover at both sites, and removed the experimental apparatus at the shallow site. Nevertheless, results yielded by surveys prior to TC Olwyn unambiguously showed strong evidence for recovery through vegetative regrowth (full recovery in cleared plots with no barriers, plus a pattern of increasing cover from the edges of the plots) and no evidence for recovery through recruitment from seeds (no seagrass was ever recorded in any cleared plot with a barrier). The main species of seagrass present was Halophila ovalis, which is widespread throughout northwestern Australia. The transferability of inferences from this study to other places in the Pilbara is hampered by the substantial variation in abundance and species composition from place to place - different species might have different mechanisms of recovery. The nature of the experimental disturbance (complete removal of all seagrass, including roots and rhizomes) is a reasonable facsimile of a severe dredging-induced disturbance, but the spatial extent of the experimental clearances (~0.5 m2) is orders of magnitude smaller than the spatial extents of dredging-induced mortality induced elsewhere: it is plausible that recovery of patches within meadows is more easily achieved through rhizome extension than recovery that encompasses spatial extents of hectares.

title: Parkes observations for project P737 semester 2014OCTS

description: Pulsar observations using the Parkes radio telescope have led to some of the most exciting astronomical results in the last few years.  The aim of this proposal is to carry out tests of the new backend instruments which cannot be carried out during standard maintenance periods. High precision pulsar timing experiments require cross-coupling in the feed to be measured.  This can only be done using observations of PSR J0437-4715 from rise-to-set.  We propose to undertake such observations and make the results available for any users of the telescope.

title: Parkes observations for project P866 semester 2014OCTS

description: Studies of the 23 MSPs in the globular cluster (GC) 47 Tucanae (47 Tuc) have provided a wealth of interesting science. Timing of these MSPs (all with periods between 2 and 8 ms) has enabled us to probe the environment and dynamics of the cluster in impressive detail and has allowed us to put constraints on the masses of several of the pulsars. However, previous studies of the cluster were limited by the hardware used. The AFB provided 1-bit digitisation and relatively coarse 88 us sampling. Through the use of the CASPSR backend, we will observe 47 Tuc and its 23 MSPs with unprecedented time resolution. For timing we will achieve almost two orders of magnitude better time resolution, allowing us to resolve out features in the profiles of several cluster pulsars, greatly improving their timing accuracy. For search purposes the CASPSR backend will provide a coherently dedispersed filterbank file at the cluster's dispersion measure. We will search this data using state-of-the-art GPU acceleration searching codes to hunt for compact binary systems.  In tandem with timing and searching, we will perform real-time transient searching to hunt for fast radio bursts (FRBs). Through shadowing with the Molonglo telescope, we will be able to provide the best localisation, spectral index measurement and repetition limits for any detected FRB. This will provide us with much needed information for multi-wavelength follow-up and will give new insight into the origins of these mysterious events.

title: Coastal bank erosion and river load data, Western Port Bay

description: This data was collected as part of two research projects commissioned by Melbourne Water that investigate the rates and processes of coastal bank erosion in Western Port Bay, Victoria. 
Most of the weather and coastal erosion time-series data commences in Nov or Dec 2012 and extends to the date of upload (currently October 2015 or earlier for some parameters). The initial project ceased in December 2013. A phase 2 project continues until December 2016, and coastal bank erosion monitoring continues until June 2016 as part of that project.
The data includes: 
*GIS layers and air photos that were used to determine long term changes in the position of the coastline. The photos start from 1947 and cover an 8.6 km stretch of banks near Lang Lang.
*15-minute tide and groundwater peizometer data collected from the monitoring site near Lang Lang
*30-minute climate data recorded by the Davis weather station installed at the monitoring site.
*Photos of the site at high and low tide each day until Nov 2013.
*River loads of Total Suspended Solids, Total Nitrogen, Total Phosphorus for gauge monitoring sites on four streams draining to Western Port. Loads were calculated from available discharge, concentration and turbidity monitoring data

title: Parkes observations for project P897 semester 2015OCTS

description: Modulation of pulse times of arrival (TOAs) from pulsars often heralds excitement: planetary companions, neutron star free precession, and the poorly understood but crucially important process of magnetospheric state switching can all produce quasi-periodic TOA modulation.  In a sample of 150 young pulsars, we have detected periodic modulation in six pulsars.  We propose to obtain multi-epoch, deep, well-calibrated 10 cm pulse profiles to search for profile variability, particularly variability correlated with TOA modulation.  The absence of such variation may lend credence to a planet interpretation, while detection will help characterize the magnetospheric states and determine if free precession plays a role.  Because the pulsars are largely southern sky objects, and because the 10cm band is largely free from RFI and scattering, Parkes is uniquely capable to deliver this science.

title: Parkes observations for project P814 semester 2015OCTS

description: During the past 6 years, we at Parkes and collaborators at other
radio telescopes have been remarkably successful at discovering
millisecond pulsars (MSPs) associated with unidentified Fermi-LAT
gamma-ray sources. Based on lessons learned, we here propose to
extend our P814 project: thus far we have discovered 11 MSPs in
repeated 1-hour searches at 1.4 GHz of 56 unidentified LAT sources
with spectral characteristics that are consistent with those of
known pulsars. Because of interstellar scintillation, large orbital
acceleration, and eclipses, it is important to search the most
highly ranked sources multiple times. Here we propose to reobserve
14 high Galactic latitude unidentified Fermi sources so that we end
up with four separate observations of each; and to observe four
times each the six most highly ranked unidentified sources selected
from the third Fermi-LAT source catalogue (3FGL) that have not yet
been searched at Parkes. The overall time request is 61 hours on
source, or 67 hours including overheads.

title: Parkes observations for project P456 semester 2016APRS

description: The Parkes Pulsar Timing Array (PPTA) project has three primary goals: (a) detection of gravitational waves from astronomical sources, (b) establishment of a pulsar timescale, and (c) improvement of our understanding of Solar-system dynamics. The PPTA is the oldest of three international pulsar timing groups. We have the smallest telescope and the smallest group, but the best measurements and the best results. Our bound on the strength of the incoherent gravitational wave background is the only bound which significantly constrains theoretical models. We have maintained our leading position because: we have the southern sky; we have a small but well-focussed group; we have the best-calibrated receivers; and we have been able to observe with an almost regular cadence of 15 to 20 days at three different wavelengths. With this proposal we aim to maintain our pre-eminent position in the field.

Unlike most observing proposals, this is a continuing proposal for which the observations will continue to improve bounds on gravitational waves until they are finally detected. Continued Parkes observations will remain valuable until the first stage of the SKA is able to offer the same sensitivity as Parkes and the same observing time. Even after the gravitational wave background is detected we will want to continue observations in support of the nascent field of gravitational wave astronomy!
