When machine learning was first invented, the infrastructure for processing earth observation data was incredibly slow, often taking days or weeks to generate results. But recent breakthroughs in hardware and software have revolutionized our ability to collect, process, and analyze geospatial data, unlocking new possibilities for research, mapping, and environmental monitoring. At the forefront of this revolution is NVIDIA, whose innovative technologies are transforming the field. In this episode, we explore the latest advancements in GeoAI hardware and architectures with Dr. May Casterline, Principal Solutions Architect with NVIDIA, and Dr. Brent Bartlette, Senior Solutions Architect at NVIDIA. Together, they share insights on how NVIDIA's unique solutions are enabling faster, more accurate, and more insightful geospatial data processing. We also examine what this means when it comes to challenges like the data bottleneck, and the ways NVIDIA is approaching these problems from a new perspective.

We’ve heard repeatedly that reliable, validated training data is one of the most important, and also most challenging components of ensuring AI models provide accurate outputs. How are we overcoming this challenge? Through Data-centric AI! Data-centric AI emphasizes the value of good data rather than model. So what are some data-centric AI approaches? We speak to Dr. Manil Maskey, Data Science and Innovation Lead, NASA Office of Chief Science Data Officer and Dr. Rajat Shinde, Computer Scientist Level IV, NASA IMPACT, University of Alabama in Huntsville to find out!

AI is a hot topic these days, but when it comes to geoscience, how is it actually being used? To answer this question, we speak to Dr. Caleb Robinson, Principal Research Scientist, Microsoft AI for Good Research Lab. Dr. Robinson shares insights into the transformative power of AI within the field, providing several interesting examples of how GeoAI is revolutionizing the analysis of satellite data for Earth observation purposes. We also cover the many opportunities available with this growing field, as well as the challenges that need to be addressed to ensure AI is a help as opposed to a hindrance.

Imagine a world where scientists can predict natural disasters before they strike, where we can monitor the health of our planet in real-time, and where we can uncover the secrets of Earth's hidden resources.

Welcome to the future of geoscience, where AI is revolutionizing our understanding of the planet! In this season of Down to Earth, we’re exploring the uncharted territories of AI in geoscience, from the groundbreaking capabilities of supercomputing to the revelatory insights of Geospatial Foundation Models.

As AI challenges and reshapes our understanding of Earth's systems, it also presents some complex, and sometimes unexpected, cultural and social implications. Through deep conversations with visionaries, innovators, and researchers, we'll explore the promises and pitfalls of this technological revolution and we’ll dare to ask the ultimate question: Will AI unlock the secrets of our planet, or, will it lead us down a precarious rabbit hole, we have yet to imagine? Find out this fall on season 6 of Down to Earth: A Podcast FOR Geoscientists BY Geoscientists!

From its role in sustaining and nurturing our bodies to its cultural and social significance, food is a key component of human life. It’s also in serious jeopardy due to climate change. In this episode, we speak with Dr. Inbal Becker-Reshef about her work in the field of food security. Together, we delve into the critical role of geospatial technologies in monitoring agricultural systems, assessing crop health, and predicting yield fluctuations through programs including the GEOGLAM Crop Monitor for Early Warning initiative. Through our discussion, Dr. Becker-Reshef teaches us how geoscientific approaches can shape the future of food security and sustainability.

According to the UNU Institute for Water, Environment and Health, water-related disasters (WRDs), including floods and droughts, account for 90% of natural disasters. These disasters result in significant loss of life each year, not to mention the billions spent on managing and rebuilding afterwards. As the global water crisis continues to grow, so too does our need for tools, techniques, and policy that will help us more effectively predict, respond to, and prevent WRDs. In this episode, we speak to Dr. Hamid Mehmood, Economic Affairs Officer with United Nations ESCAP to find out how we can address WRDs with technology.

What’s the difference between glaciers and sea ice and why do we need to be studying sea ice to better understand climate change? In this episode, we speak to two experts who study sea ice in the arctic and antarctic respectively. Dr. Anja Frost and Dr. Sven Jacobsen share their concerns about the pressing issue of the Arctic’s vanishing sea ice, the need to understand the relationship between ocean waves and sea ice depletion, and how remote sensing techniques are improving our understanding of Arctic sea ice changes. Together, both Anja and Sven use their expertise to support ships travelling through the arctic. Their research helps to optimise ship navigation, reduce emissions, and improve the technologies and processes for studying sea ice using remote sensing.

As far back as 2014, Dr. Eric Rignot, specialist in glaciology, has been informing us that some of our glaciers are melting faster than we can save them. Yet, this knowledgeable and passionate scientist continues to advocate for hope. In this episode we’ll dive deep into the meltwater to not only understand glacier behaviour, but how we can proactively deal with the results.

Methane is a dangerous gas has more than 80 times the warming power of carbon dioxide over a 20-year period. Methane is a major contributor to global warming. But the good news is, unlike CO2, methane has a very short atmospheric lifespan – around 10 years to be exact. In this episode, we speak with Dr. Ritesh Gautam who is an expert in atmospheric sciences, explores the impact of methane as a potent greenhouse gas and shares news of a new satellite mission that will help us cut methane emissions in half by 2030!

Whenever we think of greenhouse gases, carbon dioxide is top of mind. But a more nefarious gas is gaining notoriety: Methane. Not just restricted to agricultural emissions, methane is also found in the Earth’s permafrost, which is melting at an increased rate due to climate change. It’s a vicious cycle that we seriously need to interrupt. So in this episode, we delve into the critical issue of permafrost thaw and its implications for methane release with Dr. Annett Bartsch. Dr. Bartsch, a leading researcher of permafrost, shares the satellite observations and modeling techniques used to track permafrost thaw and highlights the consequences of methane emissions on our climate system.
