Observing storm surges from space: Hurricane Igor off Newfoundland
Coastal communities are becoming increasingly more vulnerable to storm surges under a changing climate. Tide gauges can be used to monitor alongshore variations of a storm surge, but not cross-shelf features. In this study we combine Jason-2 satellite measurements with tide-gauge data to study the s...

Coastal communities are becoming increasingly more vulnerable to storm surges under a changing climate.
