Animation of “dye” concentration from New River Inlet on May 11th 2012. Dye concentration is derived by differencing measured light at two wavelengths and is indicated by the black color. Dye is released in a single bomb up the inlet ~500 m from the junction with the inter-coastal waterwaterway (ICW). It propagates downstreamon the ebb tide. Unlike previous releases, the dye spreads across the entire channel and exits both the old and new channels. However, the tide switches to flood and sucks back the dye that was leaving the old channel.
