Embracing Geostatistics for Informed Decision-Making Geostatistics, born in the innovative mind of Georges Matheron in the 1950s, has evolved into a powerhouse for spatial data analysis. Originally applied in mining to estimate ore reserves, its journey now spans various disciplines, with one notable arena being Petroleum Engineering. Petroleum Reservoir Optimization: Geostatistics, with its focus on spatial relationships, plays a crucial role in petroleum engineering. Reservoir characterization, subsurface property modeling, and recovery strategy optimization benefit from its ability to quantify spatial variability and uncertainty. Spatial Patterns in Earth Sciences: From predicting mineral distributions in mining to assessing groundwater contamination in environmental studies, geostatistics enables us to unravel intricate spatial patterns, providing valuable insights for decision-makers. Agriculture, Urban Planning, Ecology, and More: Beyond petroleum engineering, geostatistics finds application in agriculture, urban planning, ecology, and geography. It aids in optimizing field management, urban development planning, understanding biodiversity, and mapping geographical phenomena. Quantifying Uncertainty: Geostatistics isn't just about predictions; it's about understanding and quantifying uncertainty. Variograms and methods like kriging offer robust tools to estimate the variability of data, ensuring decision-makers are well-informed. Geostatistics: Navigating the Spatial Landscape: As we navigate an era demanding precision and sustainability, geostatistics stands as a beacon. Its ability to unravel spatial intricacies empowers decision-makers across diverse fields, contributing to more informed, strategic choices. #Geostatistics #SpatialAnalysis #DecisionMaking #InnovationInTheSpatialRealm

How #remotesensing and #sensorfusion technologies can provide valuable information for #greenhouse gas inventory and #biodiversity protection? Peatland is a type of wetland where dead plants, mainly mosses, accumulate over time and form a thick layer of organic material called peat. This peat builds up in waterlogged, low-oxygen conditions, preventing the plant material from fully decomposing. Peatlands are important for the environment and can perform a variety of important functions, such as filtering water, storing carbon, and providing habitat for wildlife. Therefore, it’s essential to monitor the natural peatland over time and detect its changes. We’ve proposed an encoder-decoder-based architecture for peatland classification that fuses two open-source satellite data, Sentinel-1 and Sentinel-2. We show the effect of fusion by comparing the multi-modal fusion architecture with uni-modals which are trained only based on one input data source. We also investigate the influence of skip connections as the main component of the encoder-decoder to recover fine-grained details that are lost during the downsampling process. All implementation and development stages have been done at Teknillinen tiedekunta – Faculty of Technology (University of Turku) in Turun yliopisto - University of Turku The experimental results are acquired on a study area in Finland which covers a variety of minerotrophic aapa mire peatlands. The dataset was collected by the Geological Survey of Finland (GTK) / Geologian tutkimuskeskus (GTK) to train the multi-modal fusion architecture for automatically labeling a pixel in a raster dataset to a specific category of peatlands. The paper was presented at the 27th International Conference on Information Fusion 2024 in Venice, Italy. I will share the article as soon as it is published and put its link in the comment. Lastly, I am so grateful for the opportunity to be a part of this wonderful project and work with like-minded, well-established, and highly talented scientists: Luca Zelioli, Fahimeh Farahnakian, Maarit Middleton, and Jukka Heikkonen. #informationfusion #datafusion #sensorfusion #artificialintelligence #machinelearning #deeplearning #datascience #monitoring #autonomoussystems #multimodal

Hi All, Todays the day for our October Tech Talk, presented by Dr Sarah Buckerfield from Geoscience Australia! Sarah would like to provide the opportunity for attendees to hang around to discuss future potential airborne geophysical surveys so be sure to come along! As usual, this talk will be open to both members, and non-members. Topic: A tale of paleo valleys and declining river flows: mapping the saline and fresh groundwater systems of the upper Darling floodplain and understanding the controls on their occurrence Presenter: Dr Sarah Buckerfield Where: WSP Office Sydney - Level 27 When: Tuesday 08 October Time: 17:30 for an 18:00 start Event Info: https://lnkd.in/gvhZxiNJ Online: Teams link has been provided on the event info page Abstract: Communities and ecosystems along the Darling-Baaka River have been impacted by critical water shortages and water quality issues including high salinity, algal blooms, and fish kills due to declining surface water flows. The river is characterised by naturally highly variable flows and is the primary water source for the region, but extraction and a meteorological drying trend associated with climate change have caused declines in discharge of 53–73% since the advent of post-settlement agriculture and industry. Understanding of the spatial extent, quality, and useability of lower salinity groundwater within the surrounding Darling Alluvium, which could provide an alternative and potentially more sustainable water source, was previously limited. Here we present the findings of an integrated study combining modelled ground and airborne geophysical data, groundwater and surface water levels, hydrochemistry, lithology, and remote sensing data to delineate groundwater systems and understand the geological and hydrological controls on their occurrence. The resolution and breadth of datasets acquired and collated permit mapping of the key factors controlling occurrence and quality of groundwater aquifers, namely basement topography and hydrostratigraphy, groundwater-surface water dynamics, and inter-aquifer connectivity. On this basis the study area can be sub-divided into regions with distinctive aquifer distribution and quality, recharge mechanisms, and pressure gradients between aquifers. We also showed that the groundwater levels in the unconfined aquifer have declined, an expected outcome of the decline in discharge in the Darling-Baaka River which forms the primary recharge mechanism for the alluvial aquifers. These outputs have direct implications for key management questions including location and quantity of potentially useable groundwater, risk of saline groundwater up-coning or discharging to the river, and likelihood of groundwater extraction impacting river flows and groundwater dependent ecosystems.

🌊 Our recent paper on implementing the #Great_Lakes #Wave #Unstructured (#GLWUv2.0) forecast system at NOAA is now published in Geoscientific Model Development (#GMD)! 📝 During my time at #NOAA (just before I left), we devoted ourselves to bringing the state-of-the-art in #WAVEWATCH_III wave model, which we spent nearly 7 years enhancing for coastal capabilities and modernization, into operational use. The aim of this wave forecast system is to ensure the safety and efficiency of maritime activities in the Great Lakes region. Our paper delves into three key aspects of our work: 1- Operational Guidelines: We developed a robust framework for operationalizing models in highly restrictive environments, such as #NCO/#NCEP/#NWS, ensuring reliability even in the most critical forecasting situations. This framework encompasses aspects such as model reproducibility, simulation time, and coding standards. The outcome was a system that the operational center could operate without deep knowledge about wave models. 2- Scientific Advancements: Through rigorous scientific research, we enhanced the predictability and performance of the GLWUv2.0 model, overcoming numerous challenges posed by operational constraints. We demonstrated that the model is now capable of achieving a few-meter resolution in coastal areas without a penalty in runtime, thanks to the modernization efforts we implemented in WAVEWATCH III. 3- Future Directions: Looking ahead, we discuss the next steps for wave modeling, emphasizing how to improve wave modes across different scales, from global to coastal scales, and the need for wave observations during ice seasons. We also highlight the significance of #coupling our model with other Earth system components like #circulation, #ice, and #hydrology for better forecasting. Our validation against in situ data, covering both summer and wintertime conditions, demonstrates the reliability of GLWUv2.0 in diverse scenarios, including ice season challenges. This article not only sheds light on our achievements but also underscores the ongoing commitment to advancing wave forecasting technology for safer maritime operations in enclosed basins like the Great Lakes. My heartfelt gratitude goes out to my colleagues and friends, Saeideh Banihashemi, Jose-Henrique Alves, Aron Roland, Tyler Hesser, Jane McKee Smith and @Mary Anderson Bryant, whose dedication and expertise were invaluable throughout this endeavor. The GLWUv2.0 is in operation since May 9th, 2023. #WaveModeling #GreatLakes #NOAA #ERDC #CHL #Science #Research #Forecasting #MaritimeSafety 🚢💡

In our latest article, we spoke with Joel Pumple, Permafrost ArChive Science (PACS) Lab Manager, to see how the lab's #MSCL-S system has been used since its installation in 2020, and to learn about Joel's latest paper ‘Non-destructive multi-sensor core logging allows rapid imaging, measurement of bulk density and estimation of ice content in permafrost cores.’ Alongside discussing methods and results, Joel explained that "we want to capture all the data from core in its frozen state, so that we have a digital archive, and can keep the core for future studies that might require a more destructive approach." Check out the full article here: https://lnkd.in/ehrEkmwV It was really interesting to learn how the PACS lab team at the University of Alberta have been using the MSCL-S for their research for understanding #climatic and #environmental change in #permafrost regions, and how they tackle the challenge of working with sub 0°c core!

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.
