AGU 100

Top 100 Advances in Geodesy

To celebrate the AGU Centennial, the Geodesy Section is recognizing compelling advances in geodesy in the last 100 years including:
• Science – research advances in understanding Earth and Earth processes
• Technology – advanced in instruments, field work, hardware and other technological endeavors
• Data – advances in computation, data analysis, data management, and software
• Education – advances in education (formal or informal) or education research
• Broader Impacts – advances in applied science, science management, community engagement, and societal benefits

Submissions accepted through the start of AGU 2019 Annual Meeting.
Please submit your advances via email to the AGU Geodesy Section Centennial Committee (Vicki Childers, Tim Dixon, and Linda Rowan) at geodesyadvances@unavco.org with subject heading "100 Advances in Geodesy".

1978: Seasat, 1st Earth-orbiting satellite for remote sensing of Earth's oceans with 1st spaceborne synthetic-aperture radar (SAR). Demonstrated global monitoring of oceanic phenomena & determined requirements for ocean remote sensing. Tech Adv 68

1955: Gold showed mass redistribution on the surface or in the interior of Earth would result in a reorientation of the body w/respect to spin axis orientation. Subsequent studies of true polar wander advance understanding of Earth. Gold 1955, Sci Adv 67
2001: Measuring water loads with GNSS. van Dam et al. (2001) observed water loads in vertical component time series from nascent IGS network using models to quantify effects of groundwater, snowpack, & soil moisture. Tech Adv 66
1978: Seasat, 1st Earth-orbiting satellite for remote sensing of Earth's oceans with 1st spaceborne synthetic-aperture radar (SAR). Demonstrated global monitoring of oceanic phenomena & determined requirements for ocean remote sensing. Tech Adv 68
1970-1972: Used signal processing tools to extract an isostatic Green's Function (GF) from topographic and gravity data. Showed local isostasy, could be extracted from GFs. Dorman & Lewis 1970, Lewis & Dorman 1970, Dorman & Lewis 1972. Data Adv 65
