🌍👋 In 2020, Argentina implemented the Preventive and Mandatory Social Isolation (ASPO) due to the COVID-19 pandemic. This historic event reduced economic activities and people's movement, leading to a decrease in harmful gases in the atmosphere. Our research analyzes the variations of nitrogen dioxide (NO₂) before and during the pandemic in southwest Buenos Aires using Sentinel 5P images and Google Earth Engine. The results showed a gradual decline in NO₂, especially in larger cities, due to reduced human activities. We utilized geotechnologies to visualize these areas and developed a web viewer hosted at the Geotechnology Laboratory of the National University of the South. https://lnkd.in/eMJBpFtD This study was made possible by the teamwork of the laboratory: Lucía Laffeuillade, Victor Hugo Peñas, Alejandra Geraldi, and Federico Gastón Barragan. 🤝 For more information, you can contact the laboratory and access the full article with the script here: https://lnkd.in/egmtKJ_S #EnvironmentalStudies #COVID19Impact #Geography #AirQuality #NO2Reduction #ASPO #BuenosAires #Research #Teamwork #Geotechnologies

Seeing red may mean you’re angry on dry land, but in the Ocean’s Twilight Zone, BEING red might mean you're invisible! According to the experts over at NOAA Ocean Exploration, many of the residents of the Twilight Zone – between 200 to 1,000 meters – are red or black because these colors are not easily observable in the absence of sunlight. “Sunlight contains all of the colors of our visible spectrum; these colors combined together appear white. Red light has the longest wavelength and, therefore, the least amount of energy in the visible spectrum,” NOAA explains. This siphonophore is a colonial organism, with each member of the team performing a specific job, such as digestion, movement, or reproduction. It was spotted during the current #NazcaHighSeas expedition — a collaborative effort between Schmidt Ocean Institute, the University of New Hampshire Center for Coastal and Ocean Mapping Alumni, the Ocean Census, and an international contingent of scientists. The crew of Falkor (too) and the science team are collecting comprehensive seafloor mapping data and, using ROV SuBastian, characterizing the biodiversity of life along several seamounts at the Nazca and Salas y Gómez junction.

🛰 🏜 🌡 Land surface temperature (LST) is an important climate system variable used for various purposes, including climate, environmental, and natural hazard studies. The availability of spatially and temporally continuous LST time series with high resolution is critical for a wide range of disciplines including #hydrology, #ecology, and #geology as well as numerous application fields and studies concerning #sandstorms and #desertification. In our recent work, just published in Ecological Informatics (Elsevier), we reconstructed #MODIS #LST images using #temporal and #spatiotemporal models and compared their results. Since in the study region, #Yazd-Ardakan plain, LST varies significantly in time and space due to high desert conditions, the multi–channel singular spectrum analysis, a spatiotemporal model, showed better performance in reconstructing daytime and nighttime LST images compared to temporal models, like the harmonic analysis of time series. We also investigated the relationships between land use/cover (#LULC) classes and LST in this region.

Let’s dive deeper into the process of integrating new assets into Seventy Ninth Resources’ portfolio. In this video, William Slater discusses how combining historical data with advanced techniques like remote sensing and satellite imagery has revolutionised exploration over the past 15 years. This comprehensive approach allows us to make informed decisions about which projects to pursue and develop. P.S.

This is how PhDs should start! 🙌👏 Thrilled to share the outstanding achievement of our teammate Filip Gałdyn, whose groundbreaking research article titled "Long-term ice mass changes in Greenland and Antarctica derived from satellite laser ranging" has just been published in the prestigious journal Remote Sensing of Environment, with an impressive Impact Factor of 13.5! 🚀📚 Full article here -> https://lnkd.in/djrBVcrS 🔍 In the article, we demonstrate that Satellite Laser Ranging (SLR) opens new avenues for studying ice mass changes in polar regions, providing unprecedented insights. The reprocessing of historic SLR data reveals that there were no significant ice mass changes in Greenland and Antarctica during the 90s. Another critical finding highlights that Greenland experienced the most substantial ice mass loss between 2010 and 2015, emphasizing the urgency of addressing climate-related challenges. Interestingly, the process of ice loss decelerated from 2015 to 2019, only to accelerate again afterward, indicating dynamic and complex environmental changes. 🎉 I am proud of Filip Gałdyn and the whole team from Uniwersytet Przyrodniczy we Wrocławiu (me and Krzysztof Sośnica) and @University of Bern (Ulrich Meyer and Jaeggi Adrian) for dedication, hard work, and contribution to advancing our understanding of the planet Earth! 🌍❄️🙌👏
