A 30-year study reveals 77% of Antarctica's coastline remains stable, but vulnerable sectors lose 5,000 sq mi of ice equivalent to 10 cities the size of LA every three years. Researchers use satellite data to measure glaciers and grounding lines, providing crucial benchmarks for ice sheet models and mass balance assessments.
Researchers have developed a GNSS-only method that consistently outperforms existing methods in dense urban areas, enabling safer and more reliable autonomous navigation. The approach uses a probabilistic framework to estimate position without relying on carrier-phase integer ambiguity resolution.
A new study published in Earth's Future journal reveals that sea-level projections from the 1990s were remarkably accurate, with global sea-level rise averaging about one eighth of an inch per year. The researchers compared these projections with recent satellite measurements and found a remarkable match.
Researchers found that ocean anomalies traveling northward affect the Atlantic Meridional Overturning Circulation in the Nordic Seas, controlling its strength. The study suggests that these anomalies can be monitored using satellite data, providing a cost-effective way to track climate changes.
Researchers used SWOT satellite data to confirm that two mega tsunamis triggered by landslides caused trapped waves in the fjord. The study provides new insights into ocean extremes and how climate change affects remote areas.
Researchers estimate a total ice mass loss of 3213 Gt, equivalent to 8.9 mm global sea level rise, from 1996 to 2021. The Antarctic Ice Sheet's mass loss accelerated since 2006, with an increase in annual losses.
A recent study combined elevation data of the Antarctic ice sheet from two different satellites, CryoSat-2 and Sentinel-3, to obtain a more accurate map of latest elevation changes. The results showed that the average elevation of the ice sheets had decreased at a rate of 4.3 cm/year during 2016-2019.
Researchers at Carnegie Mellon University are developing a new approach to harness the power of nanosatellites, collecting data insights while in orbit and reducing latency issues. This initiative will lay groundwork for innovative applications in fields like carbon mapping, traffic management, and precision agriculture.
Researchers created wind-wave maps of East China Sea using satellite altimeter data and atmospheric reanalysis. The study reveals wind-wave climate patterns, including the similarity among multiple data sources, but also highlights limitations in describing marginal-sea wind-waves.
