Large-scale bedrock outcrop mapping on the NE Atlantic Irish continental margin - Frontiers in Marine Science: The Irish continental margin (ICM) encompasses many complex sedimentary basins and diverse geomorphological features displaying bedrock outcrops where a large variety of habitats can be observed. This large area of seabed extends over >400,000 km2 and cannot be mapped manually or in a standardized way. Novel bedrock suitability mapping is applied to the entire ICM to determine potential bedrock outcrop from shallow to deep settings and to improve on the regional near-surface geology of the Irish margin. With the use of ROV video transects covering all the ICM and multibeam echosounder dataset, key terrain variables diagnostic of bedrock outcrop have been derived from bathymetry. A reclassification of each terrain variable was created by identifying the suitable ranges for outcrop occurrence in the variables, corresponding to the most common values occurring where the bedrock is located. Suitable bedrock location in non-surveyed areas have been calculated using these variables with map algebra to develop the novel Bedrock Suitability Index. This high-resolution (25 m2) model indicates that the main features where outcrop could be observed are canyon heads, terraces, or failure scarps, especially noticeable on the Whittard Canyon system. The Bedrock Suitability Index model is validated by video observations of bedrock exposures and is established with 58% level of confidence with 25 m2 resolution on the overall margin over >400,000 km2. The BSI mapping suggests a structural control on bedrock outcrop occurrences, with high BSI correlating with deep structural fabrics of the margin as bedrock outcrop can be found in areas where previously mapped faults have been identified. Bedrock and hard substratum mapping are important components to improve habitat identification and mapping. This less-invasive, low-cost method can be applied with open source software in a relatively simple way of determining where bedrock could be found. It can also be used to refine areas where there will be simply too much data for use to manually classify. Potential bedrock outcrop mapping can be included in a species distribution model. https://lnkd.in/eCE2BQZT

Pleased to share a new publication by members of the Quantitative Clastics Laboratory (Bureau of Economic Geology) and the UT Jackson School of Geosciences is now available Open Access in a Geological Society of London Special Publication on Meandering Streamflows. We use 37 years of Landsat satellite imagery and new methods of automated channel mapping and tracking to explore linkages between channel curvature and the spatiotemporal extent of cutoff impact for three meander cutoffs along the Trinity River in Texas. We also assess the predictability of post-cutoff bend kinematics through application of the simple numerical model of meandering first put forth by Howard and Knutson (1984). Thanks to co-authors Zoltán Sylvester, Paul Morris, David Mohrig, and members of the Quantitative Clastics Laboratory consortium for supporting this work.

🔊New Publication Alert: Advanced Geohazard Monitoring Through Satellite Data🔊 I am pleased to announce the publication of our recent research article, a joint work with Simone Vantini, Mara Bernardi, Alessandra Menafoglio, Francesca Cigna e Deodato Tapete, titled "Identification of Precursors in InSAR Time Series Using Functional Data Analysis Post-Processing: Demonstration on Mud Volcano Eruptions". The paper describes an interesting "statistical" in the field of inSAR data post-processing, geohazard mapping and early warning systems. Abstract Overview: Our study introduces an innovative post-processing technique that utilizes Functional Data Analysis to analyze ground displacement data derived from satellite radar imagery. This method is meticulously designed to detect early precursors in displacement time series without the need for predefined deformation models, while also accounting for the inherent spatial and temporal data dependencies. The practical application of our method is exemplified through its successful deployment in predicting a mud volcano eruption in Sicily, providing a timely warning months ahead of the event. The paper is available here: https://lnkd.in/guKzwDS9 This publication shows how advanced statistical methods can be used to provide more and better information to public decision makers, in order to guide their decisions in a more data-driven and science-informed way #GeohazardMapping #SatelliteData #FunctionalDataAnalysis #EarlyWarning #ResearchPublication

The Importance of "Boots on the Ground" for Geologists In an Anthropocene dominated by digital technology, remote sensing and AI, the role of fieldwork in geology remains indispensable. While satellite imagery, GIS and computer models provide valuable insights, there's no substitute for the tactile, hands-on experience of being out in the field and lick the rocks. Exploratory fieldwork allows geologists to evaluate, validate and refine data obtained through remote methods, ensuring accuracy and reliability. On-site investigations enable the discovery of geological features that might be missed from afar, providing a comprehensive understanding of the lithology and terrain. Understanding the geological context in relation to the surrounding environment is crucial for sustainable resource management and conservation efforts. Fieldwork hones essential skills such as critical thinking, problem-solving, and adaptability, which are vital for addressing complex geological challenges. Let's value the essence of "boots on the ground" in geology, where every step leads to new discoveries and a deeper connection with our planet! 🌎 Note: Image used from R. H. Sillitoe, 2024.

https://lnkd.in/gDSjy-8K Please check out our article just published in Earth Science Reviews. We use basin-scale 3D modeling to document the nature of flexural extension in the Arkoma Basin pro-foreland. Inherited NE-trending basement fault zones segment the younger, ~E-W normal faults, which accommodate the downflexure of the basin. Check it out!
