Satellite data reveal Southern Ocean vertical currents diving 3,000 feet below surface
June 9, 2026 report Satellite data reveal Southern Ocean vertical currents diving 3,000 feet below surface Paul Arnold Author Lisa Lock Scientific Editor Robert Egan Associate Editor Ocean currents are not just horizontal motions that flow from side to side. There are also vertical currents that act like deep-sea elevators, pushing heat and carbon down into the deep, while bringing up vital nutrients and dissolved gases to the surface. Our knowledge of these vertical movements has been...
Tracking Urban Atmospheric Pollutants using Sentinel-5P Satellite Data
Announce Type: cross Abstract: Urban nitrogen dioxide ($NO_2$) is a key indicator of combustion-related air pollution and exhibits strong spatial and temporal variability in cities. This study presents a satellite-based framework for tracking urban $NO_2$ pollution using tropospheric column observations from Sentinel-5P/TROPOMI over Guayas Province, Ecuador. Rather than estimating surface concentrations, the methodology emphasizes robust distributional metrics, including the median and...

SWOT satellite gets clearer ocean data after fix for hidden underwater wave interference
SWOT satellite gets clearer ocean data after fix for hidden underwater wave interference Sadie Harley Scientific Editor Robert Egan Associate Editor Florida State University research published in Science Advances demonstrates a new framework for predicting the motion of kilometer-scale underwater waves that complicate satellite readings of the ocean. By accurately modeling these subsurface waves, scientists can remove their interference from NASA's Surface Water and Ocean Topography, or...
Satellites add a new layer to global poverty data
A new study using satellite data finds that 58% of the global population has been assigned to the wrong tier in the UN's Human Development Index. That can have real-world consequences for how aid reaches people.
Satellite images show Israel’s destruction of historical city of Tyre
Satellite images show Israel’s destruction of historical city of Tyre Satellite data shows damage to residential areas, UNESCO World Heritage buffer zones and Palestinian camps in Israeli attacks. Newly evaluated satellite images show widespread destruction across the southern Lebanese coastal city of Tyre, following a relentless wave of Israeli air strikes after systematic forced displacement orders. An analysis of the images by Al Jazeera’s open-source unit, which compared satellite data...
In the world's economic 'black holes,' data still leak out
From satellite imagery to clandestine price reports, a new study draws on North Korea to explore economic activity in opaque regimes and information-scarce regions. North Korea is the blackest of economic black holes. Even a basic question like "is the economy shrinking or expanding?" can be difficult to answer.
Tessera AI model offers accessible way to view Earth
Tessera AI model offers accessible way to view Earth Lisa Lock Scientific Editor Andrew Zinin Lead Editor A foundation model trained on Earth observation data from Copernicus Sentinel-1 and Sentinel-2 has been made widely available to researchers, it was announced at a computer industry conference this week in Denver, U.S. Tessera, an advanced artificial intelligence (AI) model, offers high-accuracy datasets that encode what the satellite "sees" of Earth's surface during the course of a...
Amplified Arctic iceberg traffic reshapes benthic biodiversity
Abstract The Arctic is undergoing rapid warming, resulting in retreating sea ice and glaciers1, yet how cryospheric changes propagate into the deep ocean remains poorly understood2. Here we identify a climate-driven mechanism linking accelerating glacier disintegration to an increase in deep-sea hard-bottom habitats far beyond calving fronts. Seafloor observations in Fram Strait show a localized increase in the density and patchiness of dropstones delivered by debris-laden icebergs.
