Pacific Sea Level and Geodetic Monitoring Project, Levelling & GNSS Monitoring Survey Report Funafuti, Tuvalu, October 2019

The Australian Bureau of Meteorology (BoM), Geoscience Australia (GA) and the Pacific Community (SPC) work together on the Australian Aid funded Pacific Sea Level and Geodetic Monitoring Project (PSLGMP). The project is focused on determining the long-term variation in sea level through observation and analysis of changes in the height of the land (using Global Navigation Satellite System (GNSS) data) and changes in the sea level (using tide gauges managed and operated by the BoM. It is the role of GA and SPC to provide information about ‘absolute’ movement of the tide gauge (managed by BoM) using GNSS to continuously monitor land motion and using levelling (SPC) to measure the height difference between the tide gauge and GNSS pillar every 18 months.

Land movement caused by earthquakes, subsidence and surface uplift have an important effect on sea level observations at tide gauges. For example, a tide gauge connected to a pier which is subsiding at a rate of 5 mm per year would be observed as a rate of 5 mm per year of sea level rise at the tide gauge. Because of this, it is important to measure, and account for, the movement of land when measuring ‘absolute’ sea level variation - the change in the sea level relative to the centre of the Earth. Relative sea level variation on the other hand is measured relative to local buildings and landmass around the coastline.
Geoscience Australia’s work enables more accurate 'absolute' sea level estimates by providing observations of land motion which can be accounted for by BoM when analysing the tide gauge data.

This report provides the results of the GNSS monument monitoring survey & high precision level survey completed between the Sea Level Fine Resolution Acoustic Measuring Equipment (SEAFRAME) tide gauge and the GNSS Continuously Operation Reference Station (CORS) in Funafuti, Tuvalu in October of 2019. It also provides an updated height of the tide gauge derived from GNSS time series analysis and precise levelling observations.

National Coastal Geomorphology Information Framework: Discovery and Distribution

Geoscience Australia collaborated with the Department of Climate Change and Energy Efficiency (DCCEE) in a national programme of work that focused on an assessment of the vulnerability of Australia's coastline to the impacts of sea level rise. This program aimed to:
- develop the first phase of a nationally consistent geomorphic classification of coastal landform types of the Australian coastal zone
- catalogue the available polygon geomorphology/geology digital maps and datasets of the Australian coastal zone.
- reclassify these maps and datasets with a nationally consistent geomorphic classification scheme, and develop a national geodatabase that contains the reclassified digital maps of geomorphology and landform types of the Australian coastal zone.
Completion of the programme of work described above (Schedule 1 under the Collaborative Head Agreement with the DCCEE) resulted in the creation of the National Coastal Geomorphology classification and geodatabase. This data is underpinned by pre-existing spatial data sourced from local, state and federal government agencies that were reclassified to conform to the new National Coastal Geomorphology classification scheme.
This report describes the rationale and workflow for the management and distribution of the National Coastal Geomorphology data undertaken as part of 'Schedule 10', the subsequent phase of this programme. Geomorphology data, together with elevation, hazard and exposure data, underpin assessments of coastal vulnerability for current and future climate conditions. Therefore it is critical that these data are made available to coastal scientists and land use management and planning stakeholders and the community. The purpose of the work described in this report is to establish a mechanism to manage and distribute the National Coastal Geomorphology data and the newly created National Coastal Geomorphic classification scheme.
The future work section of this report makes recommendations around the next stage in the development of this dataset. A key issue is the development of a formal governance model to enable a comprehensive revision and maintenance program of the data and the classification scheme, and ensure sustainability through continued stakeholder engagement in the product.

Quantitative mapping of the East Australian Current encroachment using time series Himawari-8 sea surface temperature data

The East Australian Current (EAC) is a complex and highly dynamic western boundary current (WBC) component of the South Pacific Gyre. The interaction between the EAC and the continental shelf significantly influences the coastal ocean dynamics and the marine ecosystem off the southeast coast of Australia. In this study, we attempted to map the spatial structure of the sea surface temperature (SST) signature of the EAC system using Himawari-8 SST data, and to investigate the spatial and temporal evolution of the EAC encroachment for the period July 2015 to Sept 2017. The very high spatiotemporal resolution of Himawari-8 SST images has enabled the mapping of the highly dynamic EAC using a Topographic Position Index (TPI) method. The results demonstrated that the TPI mapping was able to capture the complex spatial structure of the EAC system, based on which the spatial variability and temporal evolution of EAC’s meanders, offshoots, separation, eddies, and extensions along its path have been clearly documented. Using an eddy-resolving, data assimilating numerical ocean model, we were able to relate the EAC's SST signature with its surface current speed signature, with an overall area ratio of overlap ~60% between the two signatures. Temporal wavelet analyses indicated that the variability of the EAC encroachment is dominated by an eddy-shedding timescale, being 65~80 days upstream and 90~100 days downstream of the EAC separation point. In the upstream, the EAC’s proximity to the coast also exhibited seasonal cycle in the 2 year (26 months) study period, with the encroachment being stronger during austral summer and weaker during austral winter. Off the eastern coast of Tasmania, powerful summer pulses of the EAC encroachment were observed, which is an expression of the seasonality of the EAC boundary flow in this region. Upstream, we believe that the “encroach and accelerate” mode of the EAC would drive coastal upwelling which can occur all year round with local maximum typically in summer. Downstream, the “encroach and decay” mode of the western arm of the EAC or its eddies is less likely to induce and sustain bottom water uplift. The seasonal current sheer previously observed upstream on the continental shelf is believed to be a combined effect of the stronger EAC encroachment and the enhanced temperature difference between shelf and EAC waters (i.e. thermal wind effect) in summer compared to winter.

MRTAS D'Aguilar Range tmi vd1 grid geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This MRTAS D'Aguilar Range tmi vd1 grid geodetic is a first vertical derivative of the Total Magnetic Intensity grid for the D'Aguilar Range, Tas, 2001 (WTRMP Area E).
This grid has a cell size of 0.00042 degrees (approximately 40m). The grid has units of nanoTesla per km (or nT/km). The data used to produce the TMI grid was acquired in 2001 by the TAS Government, and consisted of 1175 line-kilometres of data at 200m line spacing and 80m terrain clearance. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.
