𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐭𝐡𝐞 𝐎𝐜𝐞𝐚𝐧 𝐅𝐥𝐨𝐨𝐫: 𝐀 𝐂𝐫𝐢𝐭𝐢𝐜𝐚𝐥 𝐒𝐤𝐢𝐥𝐥 𝐟𝐨𝐫 𝐒𝐮𝐫𝐯𝐞𝐲𝐨𝐫𝐬 As a surveyor, having a deep 𝐠𝐞𝐨-𝐮𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐨𝐟 𝐭𝐡𝐞 𝐨𝐜𝐞𝐚𝐧 𝐟𝐥𝐨𝐨𝐫 is crucial for a variety of applications, from safe navigation to resource exploration and environmental conservation. The complexity of undersea terrain, such as ridges, trenches, and submarine channels, influences everything from the placement of underwater infrastructure to the success of environmental management projects. For instance, in a recent 𝕠𝕗𝕗𝕤𝕙𝕠𝕣𝕖 𝕨𝕚𝕟𝕕 𝕗𝕒𝕣𝕞 𝕡𝕣𝕠𝕛𝕖𝕔𝕥, accurate bathymetric surveys and an understanding of the ocean floor's geomorphology were essential. These surveys were critical in determining the optimal locations for turbine foundations, ensuring they were built on stable, low-risk areas with minimal environmental impact. Without a thorough understanding of seabed conditions, the project could have faced costly delays, increased risk to infrastructure, and potential harm to marine ecosystems. 📖 Reference: Calder, B.

Pleased to announce Geoscience Australia's recent release of multiple new geological and hydrogeological datasets developed as part of our recent investigation into regional groundwater systems in the Cenozoic aquifers of the Kati Thanda - Lake Eyre Basin (KT-LEB) in central Australia. These data releases complement the earlier publication of GA Record 2024/05 on the Cenozoic geology, hydrogeology, and groundwater systems of the KT-LEB, an impressive technical report astutely developed and delivered by Tim Evans and his dedicated team of co-authors at GA.   There are four data packages now available, focusing on the key geological and hydrogeological data, as well as the new interpretive work on the regional airborne electromagnetics (AEM) data over part of Cooper Creek Floodplain, and topographic data from previous lidar surveys along Cooper Creek. Massive congratulations to Tim and Larysa Halas for their dedication and diligence in compiling these data packages and making them freely available for anyone to access, download and use in future projects.   Links to all the data packages are available directly from the 'Associations' tab on the main download page for GA Record 2024/05 on the Geoscience Australia Data and Products Catalogue here: https://lnkd.in/gkR_4i4i   #GeoscienceAustralia  

New insights about sandy pockmark fields, discussions about their genesis and geomorphological dynamic I want to present our new article about that issues - shared paper https://lnkd.in/eR3n_q-n Natural seafloor depressions, known as pockmarks, are common subaqueous geomorphological features found from the deep ocean trenches to shallow lakes. Pockmarks can form rapidly or over millions of years and have a large variety of shapes created and maintained by a large variety of mechanisms. In the sandy sediments of the southeastern North Sea, abundant shallow pockmarks are ubiquitous and occur at shallow water depths (<50 m). Their formation has previously been linked to methane seepage from the seafloor. Here, we characterize over 50,000 pockmarks based on their morphology, geochemical signature, and the subsurface pre-conditions using a new integrated geoscientific data set, combining geophysical and sedimentological data with geochemical porewater and oceanographic analysis. We test whether the methane seepage is indeed responsible for pockmark formation. However, our data suggest that neither the seepage of light hydrocarbons nor groundwater is driving pockmark formation. Because of this lack of evidence for fluid seepage, we favor the previously suggested biotic formation but also discuss positive feedback mechanisms in ocean bottom currents as a formation process. Based on a comparison of pockmarks to the central and southeastern North Sea, we find that local lithology significantly affects pockmark morphology. Muddy lithologies favor the formation of larger, long-lived structures, while sandy lithologies lead to short-lived, small-scale structures that are large in area but with shallow incision depth. We conclude that pockmarks in sandy environments might have been overlooked globally due to their shallow incision depth and recommend reevaluating the role of hydrocarbon ebullition in pockmark formation.

Geological maps are specialized maps designed specifically to display geologic features. Geologists create maps that reveal the various types of rocks and the dates of younger deposits visible on or near the Earth's surface. Planning for growth management, transportation, dam safety, assessing hazards and risks, cleaning up and restoring Puget Sound, valuing water resources, protecting and using resources, teaching, recreation, and scientific research are just a few of the numerous practical uses for geologic maps. You may also use geologic maps to locate energy resources, water, sand, and gravel. Engineers and planners use geologic maps to monitor urban sprawl and locate potential geological dangers such as faults and landslides. In their pursuit of unusual or valuable rocks, minerals, or fossils, "rock hounds" consult geologic maps. #opentowork #geophysicst #geologymap #GIS #earthscience

⛰ From Rock Cores to Roadmaps: Simplifying Geological Data for Stakeholders 🚓 All too often, geologists either don't have the skillset or the time to deliver accurate drafts and this key step in the subsurface workflow is overlooked. We see presentations full of poorly crafted images and inaccurate representations of the subsurface on a day-to-day basis - this is why Geo's are poorly understood. Our job as geoscientists is not only to interpret and represent the secrets beneath our feet, but also to depict our ideas in a digestible way to educate our management, colleagues, and the public. If you are looking to get your projects/prospects through a tricky peer review process, present a farm-out agreement, or inform the public about a specific geological issue, your material needs to follow these three KEY rules: - Be Clear: Clarity is the key to communication. 🔮 - Be Memorable: Make your images memorable to improve credibility and your chances of success. 🧠 -Be Concise: Ensure your story is concise to retain attention. ⏩ Below is an example of a sedimentary log showing the interpreted lithofacies as well as paleocurrents, illustrating the changing facies throughout the Kayenta Formation from the Colorado Plateau, USA (courtesy of Priddy & Clarke 2020).

A study was conducted utilizing #ElectricalResistivityTomography (ERT) with Wenner-Schlumberger electrode configuration to explore the distribution of #Groundwater aquifer potential in an area characterized by weathered #VolcanicRocks overlying limestone formations. The resistivity data, measured using an ARES resistivity meter with 48 electrodes, were processed using a robust inversion method to identify sharp lithological boundaries. The interpretation of the inverted model identified three lithologies: soil (1.82-5 Ωm), volcanic breccias (5-20 Ωm), and limestone (>20 Ωm). Borehole data, geological maps, and direct field observations validated this interpretation. The study revealed volcanic breccias as a potential #Aquifer in the region, with an estimated aquifer volume of 122,392,828 m³, further supporting the viability of this formation for #Groundwater resources.

I often use the principals of fractal geology to define the structural style of an area

For geological mapping, a geologist should possess core knowledge in the following areas: 1. Geologic principles: - Plate tectonics - Rock cycle - Geologic time scale - Stratigraphy 2. Rock identification: - Mineralogy - Petrology (igneous, sedimentary, metamorphic rocks) - Rock textures and structures 3. Geological processes: - Weathering - Erosion - Deposition - Diagenesis - Metamorphism 4. Mapping techniques: - Field observations - Measuring and recording data - Creating geologic maps and cross-sections - Using aerial photographs and remote sensing 5. Geologic structures: - Faults - Folds - Joints - Fractures - Unconformities 6. Stratigraphic analysis: - Lithostratigraphy - Biostratigraphy - Chronostratigraphy 7. Geomorphology: - Landforms - Drainage patterns - Glacial features 8. Data interpretation: - Geological history reconstruction - Correlation and synthesis of data - Identification of geological hazards 9. Mapping tools and technologies: - GIS (Geographic Information System) - GPS (Global Positioning System) - Remote sensing - Geophysical surveys This core knowledge enables geologists to effectively collect, analyze, and interpret data for accurate geological mapping and informed decision-making in various fields like natural resource management, environmental assessment, and hazard mitigation.

POST 3: SLICE THE CAKE Part 3 of our 5 part introduction to the web viewing platform and the southern Ontario hydrostratigraphic model. Want to see how the subsurface geology changes between Barrie and Cambridge in Ontario? Or between Kincardine and Ingersoll? It’s easy with the cross-section function of the interactive 3D model of southern Ontario. Go to ‘Cross Sections’ in the sidebar menu. You can slice the model by entering specific X, Y and Z-axis coordinates or by choosing ‘Arbitrary Line’ and drawing the area you’d bisect. (To see place names, click ‘OpenStreetMap’ under ‘View’ and adjust the opacity as needed.) To draw your own line, control-click to set each endpoint and right-click to disengage the line-drawing function. Once you’ve set your A and B points, the model opens a window showing the cross section you’ve created, complete with elevation, coordinates and the distance between points.
