Geological seabed stability model for informing Irish offshore renewable energy opportunities
<p>Climate change has driven the European Union to propose a reduction in carbon emissions by increasing renewable energy production. Although Ireland is rich in renewable energy, especially offshore wind resources, it is failing to reduce its annual carbon emissions. This study endeavours to...

| description | <p>Climate change has driven the European Union to propose a reduction in
carbon emissions by increasing renewable energy production. Although Ireland
is rich in renewable energy, especially offshore wind resources, it is
failing to reduce its annual carbon emissions. This study endeavours to
improve Ireland's marine spatial planning abilities and offshore renewable
energy developments by harmonising and customising a unique geological
dataset for incorporation into geospatial assessments of Ireland's
continental shelf. A dataset of 1858 points, including 17 new seabed
samples collected at strategic sites for this study, is created and used to
build a series of geospatial outputs. Data are interpolated with empirical
Bayesian kriging to use variogram analyses for probabilistically
interpolating coded geological values. The interpolation results are
validated through leave-one-out cross-validation and combined with bespoke
models of bathymetry and seabed slope using map algebra. The final model
reveals areas of relative probable seabed stability based on geological and
geomorphological characteristics and is shown to comport with known
conditions in several locations. Results suggest that the methods and
results presented here could provide useful information to future planning
activities and initial site selection assessments.</p> |
