Results from both WireWalkers : both deployments

All the Wirewalker data has now been processed.   Below are plots for WW1 deployment 2 and WW2 deployments 1 & 2.   Note in the plots below that the dark cross-hatched areas are times when the WW data is bad.   See the previous post for the map of the WW locations. WW1 Deployment 2 WireWalker 2, deployment 1 WireWalker 2, deployment … Read More

WireWalker #1 Deployment 1 results

We now have our first look at the wirewalker (WW) mooring observations.   The wirewalkers use the up and down motion of the sea-surface to move a CTD+fluorometer profiling package up and down the water column.   As such, good vertical and tempral resolution of the watercolumn can be acheived with a single sensor.    During RIVET-I, we deployed 2 WW in … Read More

Airborne Dye Movie from May 11th 2012

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 … Read More

Airborne Dye Movie from May 8th

We’ve also gotten the May 8th dye movie put together. Check out the youtube video or the link to the .mov file below. The dye qualitatively behaves similar to on May 7th (see previous post). However, the dye does not get advected as far downcoast.   However, there are a number of coherent structures clearly visible in the dye field.    The … Read More

Airborne dye movie from May 7 2012

We’ve been busy processing up the RIVET I data from the New River Inlet, which we will be posting to our ftp site soon. We’ve also been working up the airborne observations (in collaboration with Luc Lenain & the Melville lab). The video below shows a visualization of the May 7th dye release. Animation of repeated airborne passes of the … Read More

Dye release Sat May 19th: Balancing Dye Flux

The dye release on Sat 19 May was interesting.    30 gallons of dye were released for 5 hours starting at 0430 (AM!) in approximately 10 m water depth a few meters (3-4 m) above the bed between buoy #6 and #8 in the channel   Dye went up the inlet towards the ICW on the flood.    Dye that had reached … Read More
