Thrilled to share my poster presentation on 'Investigating the Influence of Atmospheric Blocking Morphology on Predictability' at European Geosciences Union (EGU), 2024! It was an enlightening experience to delve into the complexities of extreme weather phenomena. Grateful for the insightful comments and discussions received during the session 'Extremes in Geophysical Sciences: Drivers, Predictability, and Impacts.' Looking forward to incorporating these valuable insights into future studies. #EGU2024 #ExtremeWeather #Research

Hot off the press! Have you ever wondered when ocean circulation began through the Barents Seaway during the Quaternary period (the last 2.6 Ma), connecting the Arctic and the Atlantic oceans? Our new paper led by Henry Patton shows that this connection was established 690.000 years ago! Suppose you are a climate or ocean scientist working on climate and oceanographic simulations, or a sedimentologist trying to understand the source-to-sink or contourites distribution in the Arctic, or a structural geologist interested in glacio-isostatic or tectonic uplift reconstructions, or a landscape evolution enthusiast fascinated in numerical modelling, or anyone wanted to be updated on how the earth responded during an ice age. In that case, this paper is for you :) Read here, #OpenAccess paper in Earth-Science Reviews: https://lnkd.in/gf3fTZ9A iC3 Centre for ice, Cryosphere, Carbon and Climate (Polar Research) UiT- The Arctic University of Norway Centre for Planetary Habitability (#PHAB) University of Oslo Universitetet i Oslo (UiO) | University of Oslo The Geological Survey of Norway EarthByte Group School of Geosciences University of Sydney University of Oulu Thanks to the sponsors Equinor, Norges forskningsråd, European Commission

Dear Friends, Many of you have expertise in subsurface modeling and geophysics that has or could be applied to Mars in the context of future human exploration. In particular, heat transport for geothermal-equivalent engineered systems may play a role with subsurface fluids (should they be available). Some colleagues and I are really keen on how other technologies can be (or have been already!) adapted to work on Mars. I’m attaching the session description below and hope you will consider submitting an abstract (deadline 7/31). We also hope to assemble the insights into a set of journal articles bridging the Mars exploration and Terrestrial groundwater modeling communities. Please feel free to share with anyone else who might be interested and thanks for considering – hope to see you in DC!    Abstract: Exploration of the Martian subsurface is proceeding rapidly, driven by multiple extended missions, preparation for Mars Sample Return, post-mission assessment of InSight data, and prioritization of Mars Life Explorer and human exploration as outlined in the Decadal Survey. This exploration follows four primary themes: 1) investigating physical, chemical, and thermodynamic properties of Mars’ interior, 2) characterizing the distribution and stability of liquid water and ice inventories using novel and Earth-based methods, 3) evaluating the provenance, cycling, and isotopic composition of bio-relevant trace gasses, and 4) identifying habitable “refugia environments” where conditions could feasibly support an extant biosphere. For the seventh “New Mars Underground”, we invite abstracts that highlight these themes, particularly the scientific value that the Martian subsurface represents for planetary evolution, comparative planetology, and development of habitable environments. We anticipate contributions informed by remote observations, theoretical modeling, mission concept development, and applied experimentation of terrestrial analogs and synthetic samples.   Session ID: 230074 Convener: Yu-Feng Lin (University of Illinois Urbana-Champaign) Co-conveners: David Burtt (NASA), Michael Fienen (USGS), John Ortiz ( DOE-LANL), Chris Okubo (USGS) Session Link: https://lnkd.in/gt3mjBnb   If you have any questions, please don’t hesitate to reach out!

Exploring the depths of innovation with the Ocean Observatories Initiative 🌍 Ever wondered how we uncover the mysteries of our oceans? The Ocean Observatories Initiative is a collaboration powered by Oregon State University, University of Washington and Woods Hole Oceanographic Institution, supported by the NSF. 📃Read more: https://lnkd.in/dRf7HNpK Over 10 years, it has deployed 5 global arrays — spanning the North Atlantic, Pacific and the Gulf of Alaska. 🔭 These are home to fixed & mobile platforms with hundreds of sensors measuring everything from ocean temperatures to volcanic activity. At #CyberResiliencySummit, Oregon State University’s Craig Risien shared with #theCUBE’s Christophe Bertrand how this intricate data system is managed. “[The sensors] measure all sorts of physics, biology, chemistry and geophysics in the ocean and the seafloor, and all those data are collected and returned to Oregon State, where they're stored on our servers and distributed to those people that are interested in using them for research purposes,” he said. This collaboration isn't just science — it's a window into Earth's future. Ready to dive in? #OceanObservatoriesInitiative #DataManagement #TechInnovation

Later this April one of our Research Meteorologists, Dr Dan Smith, will be heading to Vienna, Austria, to take part in the European Geosciences Union (EGU) General Assembly conference. The General Assembly is a large week-long conference which encourages members and non-members to take part in the different programme groups available. There are main disciplinary sessions which cover topics decided by each different scientific division, transdisciplinary lectures, debates, short courses as well as education and outreach workshops all on different days throughout the week. Dan is presenting a poster in the “Aerosol Emissions and Properties, Ice Nucleating Particles, Cloud Processes and Radiative Feedbacks: From Observations to Modelling” session, linking to his research at UEA. He will also be heading to multiple different sessions throughout the week to help keep us up to date on the current science, give us ideas on how we can improve all our services, and whether there are any areas of research we could investigate. If you would like to read more about the EGU, the General Assembly and what Dan will get up to, follow the link to the article below: https://lnkd.in/eEW45EVB #EGU #Meteorology #EarthSciences #UEA #Weather

Hydrothermal vents on the ocean floor are widely considered spots where life could have originated on Earth. But Earth likely isn’t the only ocean world in our solar system, and an international team, including scientists from Blue Marble Space in Seattle, wondered if similar hydrothermal vent systems could exist on one of our celestial neighbors. Using a hydrothermal vent system located off the Pacific Northwest coast as a model, they ran computer simulations and found that the vents could exist under the ice on two distant moons (Europa and Enceladus), despite the vastly different gravities and geology to Earth. This increases the chances that life could have emerged on these worlds.

Recently published some more work on Arctic monitoring using computer vision, at the IEEE OCEANS 2024 conference in Halifax ! This is the culmination of some of my fieldwork undertaken in Svalbard last year. The paper focuses on the innovative estimation of floating ice distribution in glacial bays using aerial imagery. This floating ice influences ice-loss at glaciers by affecting key factors like buttressing, insulation, and oceanic currents. Leveraging the Segment Anything Model, we've fine-tuned it to automatically estimate floating-ice distribution, while being robust to challenges like shadow, sunlight, and water color. This was achieved by segmenting images collected from various locations in Svalbard and employing the Low-rank adaptation technique to optimize the neural net efficiently. This method addresses data scarcity and reduces the need for extensive training resources. Our findings can help enhance understanding of ice dynamics, can complement our ongoing study on acoustic monitoring at glaciers, and may also pave the way for real-time analysis of glacial changes, offering valuable insights into climate-change mechanisms in these sensitive environments. Paper available here, or can be downloaded for free from the lab webpage: https://lnkd.in/gxcEEjjE . A big thank you to everyone who supported this research and contributed to its success, including our collaborators from Scripps Institution of Oceanography, Institute of Geophysics Polish Academy of Sciences, Norwegian University of Science and Technology (NTNU) and UiT- The Arctic University of Norway! Also thanks to NUS Tropical Marine Science Institute and National University of Singapore for supporting the study. #ClimateChange #GlacialResearch #AerialImagery #InnovationInScience
