West was also manager for the radar altimetry data processing project for Seasat, the first satellite designed to collect oceanographic data. #geodesy ⚒️🧪
October 27, 1930, birthday of American mathematician and computer programmer Gladys Mae West.
She created an accurate model of the Earth's shape, and her work on satellite geodesic modelling laid the foundations for GPS technology 🛰️🌐

The idea of renaming "Greenland" to "Red, White and Blueland" must have come from our 2020 Science paper where we (Ben Smith and 14 others) used NASA's ICESat and ICESat-2 laser altimetry to show how much the ice sheet surface went up or down in 16 years.

On July 29, 2025 a Mw 8.8 earthquake off Kamchatka launched a Pacific-wide tsunami, right as the SWOT satellite flew south-to-north taking altimetry measurements of the wave train. In our new preprint, we pair SWOT with nearby DART buoys to capture the tsunami’s propagation and its source

Wide-swath satellite altimetry unveils global submesoscale ocean dynamics - Nature
Data from the recently launched Surface Water and Ocean Topography satellite reveal the characteristics of submesoscale eddies and waves and suggest that their potential impacts on overall ocean circulation is much larger than previously thought.

Wide-swath altimetry maps bank shapes and storage changes in global rivers - Nature
Observations of river channel geometry and monthly water storage changes for 126,674 river reaches worldwide are derived from the first water year of the Surface Water and Ocean Topography satellite mission.

I have a joke about laser altimetry but it's all about the timing

Observing the tidal pulse of rivers from wide-swath satellite altimetry - Nature
Data from the recently launched SWOT satellite, a wide-swath satellite altimeter, have been used to map tidal dynamics for thousands of coastal rivers and to document the factors controlling the inland extent of tides.

Such an important (and once hidden) figure in satellite geodesy and ocean altimetry.

Great news for ocean altimetry observations! 🌍🛰

Global sea level rise is also a crucial indicator of Earth's Energy Imbalance.

It takes about 50 times as much heat to increase sea levels by thermal expension of the oceans than it does from melting ice.

Satellites paint a very worrying picture!
