Why We Must Tie Satellite Positioning to Tide Gauge Data

by P. L. Woodworth, G. Wöppelmann, M. Marcos, M. Gravelle and R. M. Bingley 3 January 201730 September 2021

Accurate measurements of changes in sea and land levels with location and time require making precise, repeated geodetic ties between tide gauges and satellite positioning system equipment.

Tracking global gravity changes can help scientists better understand natural hazards like droughts and lava flows.

Tide Gauge Records May Underestimate 20th Century Sea Level Rise

Leah Crane by L. Crane 29 September 20161 November 2021

Tide gauges can help measure sea level change, but their limited locations and short records make it hard to pinpoint trends. Now researchers are evaluating the instruments' limitations.

New research suggests that monitoring changes in gravity near active volcanoes can reveal activity otherwise overlooked.
