State of the Coast

The State of the Coast

NOAA’s National Ocean Service¬†recently launched an excellent web tool – known as the State of the Coast¬†– allowing users to explore a variety of connections among coastal communities.

Susan Holmes, with the Special Projects Division at NOAA National Ocean Service, provided the following description of the State of the Coast tool:

“Within that narrow strip of land and water we call our coast, there is a nationally-significant story to tell. Our well-being as a nation depends on a suite of benefits that flow from healthy coasts: food, clean water, jobs, recreation, and protection from hurricanes. To help tell that story and encourage the need to better understand, manage, and protect our natural resources, NOAA has developed this State of the Coast (SOTC) Web site: a clear, simple, and engaging Web destination that will foster an increased awareness of the crucial importance of healthy coastal ecosystems to a robust U.S. economy, a safe population, and a sustainable quality of life for coastal residents.

The SOTC Website first offers quick facts and more detailed statistics through interactive indicator visualization maps that provide highlights of what we know about coastal communities, coastal ecosystems, and the coastal economy and about how climate change might impact the coast.  Secondly, the SOTC Web site offers case studies and management success stories that highlight often complex connections across the four State of the Coast themes: coastal communities; coastal ecosystems; coastal economy; and the climate.

Explore this site to gain a deeper appreciation of the connections among healthy coastal ecosystems, a robust U.S. economy, a safe population, and a sustainable quality of life for coastal residents…and the consequent need to better understand, manage, and protect our nation’s coastal resources.”

Bathymetry displayed in Google Earth

Bathymetry in Google Earth

The other day I was working on a project to determine feasible locations in Florida’s coastal waters to site mooring fields for recreational boaters. I had the need to “see” water depths…and fairly quickly. I was pleasantly surprised to come across bathymetric data sets for selected U.S. estuaries produced by NOAA’s National Ocean Service. Even better, the data sets are available as Google Earth Visualization Files. Thus, if you have Google Earth (GE) installed, all you have to do is click the link for your estuary of interest and the data will open in GE, color-coded to represent different depths.

These data are available in 30 meter (and 3 arc second) resolution and, as stated by NOAA, are not to be used for navigation. But they do add great value to other information that you can display in GE, such as the locations of marinas, communities, and more. If you have specific uses in mind for this data, make sure to read the information posted by NOAA to ensure that it is appropriate for your needs.
