2023 Masters by Research Call

For the first edition of the GSI Masters by Research call, with ten excellent proposals selected for funding. Projects selected include topics under GSI research areas such as Marine, Minerals, Groundwater, and Tellus.

Determining the PGE fertility of the Irish lithospheric mantle

Tile 1 Description

This project will place the first direct constraints on PGE enrichment in the mantle beneath mafic and ultramafic igneous intrusions on the island of Ireland, focussing on the Palaeogene, but also analysing older intrusions to identify changes in PGE fertility through time. The results will be of broad scientific interest for understanding mantle processes and the project will produce a comprehensive open access geochemical dataset of PGE (+ chalcophile base metal and Au) abundances in Irish mafic intrusions. Through integration with data from geologically related intrusions elsewhere in the

North Atlantic, this dataset will aid in de-risking future exploration by determining the potential for, and temporal limits of, economic Ni-Cu-PGE-(Au) mineralisation on the island of Ireland.

Assessing soil health across multiple land-use types in the Northwest of Ireland

Tile 2 Description

This project will include in-depth analysis of chemical and biological soil health indicators from Tellus and previous research projects. It will analyse soil organic matter (SOM), soil respiration, autoclaved-citrate extractable (ACE) protein, and active carbon for use as representative biological properties. We will analyse soil pH, phosphorous, potassium, and minor element composition as key chemical characteristics. The data will support complementary research by analysing soils collected in tandem with those for microbial ecology investigation, thus providing confirmation of previously collected Tellus data (e.g., pH, elemental composition). In addition, the proposed project will generate novel datasets of biological and chemical soil health characteristics that can be compared and contrasted with both other data, providing the most detailed investigation of soil health in Ireland to-date.

Towards real time remote sensing of Galway bay’s ocean noise

Tile 3 Description

The sub-sea SmartBay observatory and test site, located in Galway Bay, includes a variety of seafloor instruments whose data is continuously transferred to its onshore facility via a fibre optic cable at the sea bed in the bay. Here, the proposed project aims to turn this cable into a highly dense, 5km long array of acoustic and seismic sensors using DAS technology. The main goals of the project are (i) use DAS data recorded in Galway Bay to characterize and track key natural and anthropogenic acoustic/seismic events in the bay, covering

various time scales in ocean noise fluctuations, from ocean waves to ships traffic; (ii) develop processing workflows and strategies for long-term handling of the huge data that is DAS, with the perspective of real-time monitoring of the marine environment and time-lapse changes to the sea bed.

The development and impact of VR fieldtrips on Geoscience Curricula

Tile 4 Description

This project aims to acquire geospatially corrected photogrammetric data using a combination of low cost tools such a UAVs and smart phones. These data will be processed using well-developed photogrammetry workflows (e.g. Lim et

al., 2020) and be imported to Unity, an Open Source gaming engine, in which a student can navigate across the environment and record/read real geographic measurements (length and thickness of units, strike and dip, orientation, stratigraphic log and core samples). On a broader scale, this project will act as a pilot for a longer term aim where a catalogue of Irish and internationally recognised virtual fieldtrips will be made to support geoscience teaching in Ireland and abroad.

An Enhanced Angular Range Analysis workflow with backscatter and magnetometry for wider industrial i

Tile 5 Description

This project aims to create an objective and standardised sediment classification workflow that may be upscaled to large governmental programs. It will apply an enhanced angular range analysis to 6 broad areas of INFOMAR data: deep (+700 m); intermediate (400 m); shallow (200 m) and areas of interest to ORE development ranging from 100 to 20 m. The backscatter grids generated will be segmented and classified based on ARA-derived sediment composition. Magnetometry data will be diurnally-corrected and depth-normalised such that total and residual values can be embedded within the classification. Accuracy will be calculated using previously acquired sediment samples and a new workflow document created for the derivation of these data layers that can be adopted by governmental programs and increase industrial uptake of governmental data.

Evaluation of Spatial and Temporal Impacts of Climate Change on Groundwater Levels in Ireland

Tile 6 Description

The proposed study will develop a suite of cluster (catchment type)-specific statistical empirical models relating two indices derived from groundwater levels, namely groundwater memory and standardised groundwater level index (SGI), with principal climatic variables and catchment characteristics. A combination of clustering procedures and machine learning algorithms will be used to develop these models which provide a predictive tool to forecast the impacts of climate change on groundwater levels in differing Irish aquifer types and significant individual aquifers. Results will then be extrapolated (upscaled) to represent the spatial and temporal variations of climate impacts across the Republic of Ireland through integration of modelling results with the existing GIS platform.

Modelling the ground water flooding risk in Cork City

Tile 7 Description

This study proposes to undertake modelling to better understand the groundwater response during and after flooding. The development of this model will enable stakeholders such as the OPW, Cork City Council and GSI better understand and more importantly address the ground water flooding problems within Cork City. The outputs of this project will be added to the Ground water flood probability flooding data base maintained by GSI.

Fault & fracture stratigraphy of the Irish Carboniferous for geothermal potential

Tile 8 Description

This project aims to analyze the potential hazards caused by groundwater contamination to the groundwater ecosystems at various locations in Ireland using the datasets available in Geological Survey Ireland (GSI) and EPA. Advanced machine learning (ML) models will be developed to predict groundwater quality parameters in Ireland by training and testing datasets of various robust ML algorithms using datasets available in GSI and other national resources, for example, Groundwater Protection Data and EPA reports on groundwater quality. Predictions of developed ML models will be compared to values of existing datasets (with statistical analysis) to derive the performance of ML models in estimating groundwater quality parameters.
