TCarta Delivers Satellite-Derived Bathymetry to NOAA for U.S. Coastal Mapping Pilot

Validated with ICESat-2 Laser Data
DENVER, Colorado, 3 May 2021 – TCarta Marine, a global provider of marine geospatial products, has supplied the National Oceanic and Atmospheric Administration (NOAA) with satellite-derived bathymetry (SDB) validated by green laser altimeter data from the NASA ICESat-2 satellite for two U.S. shallow-water coastal areas.
2m SDB in Nantucket Sound, MA, produced using WorldView satellite imagery with ICESat-2 tracks overlaid.
TCarta was the subcontractor on the prime contract awarded to Woolpert, an international geospatial firm headquartered in Dayton, Ohio.
The NOAA pilot focused on two shallow-water regions that were 3,000 square kilometers in total area – one in the Green Bay area of western Lake Michigan and the other around Cape Cod and Nantucket Sound. Both areas experience natural forces that alter the underwater terrain faster t
The increasing proliferation of plant life in the Arctic may not be a massive difference-maker in the battle against global warming, new research reveals.
A Massive Study of Nearly Every Glacier on Earth Just Revealed a Devastating Trend

Earth s glaciers are shrinking, and in the past 20 years, the rate of shrinkage has steadily sped up, according to a new study of nearly every glacier on the planet.
Glaciers mostly lose mass through ice melt, but they also shrink due to other processes, such as sublimation, where water evaporates directly from the ice, and calving, where large chunks of ice break off the edge of a glacier, according to the National Oceanic and Atmospheric Administration (NOAA).
By tracking how quickly glaciers are shrinking, scientists can better predict how quickly sea levels may rise, particularly as climate change drives up average global temperatures.

In Brief:
From the vantage point of space, NASA’s fleet of Earth-observing satellites investigates connections between ecosystems that are continents apart, or right next door.
Part II
From the vantage point of space, NASA’s fleet of Earth-observing satellites joins with those of partner interagency and international agencies to investigate and illuminate connections between ecosystems that are continents apart, or right next door. With a global perspective, scientists can observe how factors like deforestation, climate change and disasters impact forests and other plant life – while also studying how changes in vegetation impact air quality, waterways and the climate. Vegetation is the primary energy source for nearly all life on Earth, so monitoring it and forecasting how it could be impacted by cl
