Back in August 2011, Hurricane Irene struck the mid-Atlantic coast.  This animated graph shows how the storm surge from Irene and the terrestrial flooding from Irene and Tropical Storm Lee (a few days later) impacted water surface elevations in the Delaware Estuary.

This post is the third in a series revisiting older data visualizations using R.  Water surface elevation data is from the NOAA-PORTS system and non-tidal flow at the Delaware River at Trenton and the Schuylkill River at Philadelphia is from USGS NWIS.  You can see similar visualizations of the impact of Superstorm Sandy in the Delaware Estuary and Barnegat Bay.  You can also check out the older version of this same visualization.

You can see the full length version of the entire event on YouTube.

Here's an app that illustrates how fertility and death rates impact the US age structure diagram over time.  The app uses a simple population model to forecast the US age structure in 100 years, starting from 2010 census data and user-selected fertility and death rates.

You can find and play with the app at https://johnyagecic.shinyapps.io/AgeStructureShiny/

Continuing on the theme of updating older visualizations into newer formats, below is a clip of the impact of Superstorm Sandy on Delaware Estuary water surface elevations.  The original MS Excel and screen capture version is posted here.  The new version developed in R with the animation package is cleaner and more portable.

The graph shows measured and predicted water surface elevations provided by the NOAA PORTS system for the Delaware River and Bay.

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 used video screen capture and MS Excel VBA - you can see it here.

With the pending 5 year anniversary of Sandy and the R animation package, the time was right to revisit the animation as a GIF.

The Delaware River Basin Commission (DRBC) just released a new app for visualizing water quality in the Delaware River Basin.  The DRBC Special Protection Waters Monitoring Program Explorer is a Shiny app that allows users to generate a boxplot and summary table of selected water quality data. The boxplot and summary table are updated each time the user selects monitoring parameter, range of years, and site type. In addition, users can display outliers (or not) and switch to logarithmic scale.
