Newest Speed Dating with the Coastal and Ocean Economies

by Monday, July 7, 2014 @ .

Hi, I’m the Coastal Economy Nice to meet you! I also go by total economy of coastal areas and I include all economic activities occurring in a coastal area. These activities include everything from marine transportation and commercial fishing to banking and home construction. Some of these things only occur along the coast, while other activities can occur anywhere in the nation. I have been called "...our nation's economic engine," and I employ over 50 million people and account for over $6.6 Trillion in Gross Domestic Product (GDP).   Ahoy There, I’m the Ocean Economy I

The History Behind Flooding in Charleston, South Carolina

by Tuesday, June 24, 2014 @

For many the idea of sea level rise and its associated impacts are thought of as future events. But, here in Charleston it’s already a part of life. Coastal flooding is a major issue that the city faces. All it takes is just the right tide, or even worse, an extreme high tide paired with a torrential downpour during rush hour, and Charleston’s streets become fingers of the Atlantic Ocean that

Taking Stock of All That Lidar

by Wednesday, June 11, 2014 @

Lidar has been collected for more than 15 years now along the coast. The earliest data sets the NOAA Coastal Services Center has out there are from 1996 (so yeah, 18 years) and the same areas continue to be collected. There are, of course, reasons for this; the primary ones being coastal storms, beach/dune change, and sediment transport. And for these dynamic processes there are few techniques tha

Geospatial Pioneer – In Memory of Doug Nebert (1962-2014)

by Wednesday, June 4, 2014 @

 The geospatial community recently lost a distinguished colleague. Doug Nebert was an incredible force behind many of the things we take for granted in modern day geospatial information systems.  Whether you knew Doug or not, his work affected you. We here at NOAA owe so much to his work with standards and distributed metadata catalogs. He played an important role in the development of the Nati

Hurricane Tracks: Past + Present = Future?

by Friday, May 23, 2014 @

Looking at Historical Hurricane Tracks With the traditional North Atlantic hurricane season about to begin on June 1, interest in previous tropical storms has begun to rise.  I am occasionally asked if one could use the Historical Hurricanes Tracks web site to look at past hurricane tracks to find a storm similar to some current one and then use that previous storm track to predict where some cu

Beach Volume Changes vs. Beach Change Volumes – Semantics or Half the Story?

by Tuesday, May 20, 2014 @

Lidar has become a huge benefit for those of us looking at coastal change. Quantifying change based on a beach profile every mile or so has been replaced by tens of millions of points every mile, increasing the resolution of the change analysis and efficacy in doing miles of shoreline dramatically. The downside is that it may have made it a bit too easy to become complacent with the results – th

On How Many Days Did It Rain?

by Tuesday, April 22, 2014 @

Calculating Raining Days for Use with OpenNSPECT I am frequently asked by users how to calculate the "Raining Days" parameter, which is required by OpenNSPECT to calculate annual rainfall runoff from an area. The concept of "Raining Days" initially seems quite simple: the number of days on which it rained. However, on many days it may rain only a few hundredths of an inch; on some days i
