Superstorm Sandy at Barnegat Bay Revisted

June 11, 2017 | AdventuresInData

Animations of continuous data in GIF format offer some portability advantages over video files.  A few years ago, shortly after Superstorm Sandy, a colleague and I developed a video of animated water surface elevations from USGS gages in Barnegat Bay, NJ as the eye of the storm approached.  That version ...

Blow Out Tide in the Delaware Estuary

April 5, 2016 | AdventuresInData

High winds in the Delaware Estuary region caused a "blowout" tide in early April 2016, where observed water surface elevations were much lower than those predicted via harmonic constituents.  Extreme low blowout tides can hamper navigation due ins... [Read more...]

Animated Flow in the non-tidal Delaware River

March 27, 2016 | AdventuresInData

The Delaware River experienced some high flow in late February 2016, providing an opportunity for an interesting animated graph of river response. This plot was developed using data from the USGS NWIS system for gauges on the Delaware River, retrieved with the excellent dataRetrieval library for R from USGS and the ... [Read more...]
