Surface Temp Movie: Combined remote-sensing IR and in situ measurements

  Below is a movie of surface Temperature at the New River Inlet on May 7th 2012 during the ONR-funded RIVET I experiment.   The temperature is derived by combining airborne IR (Luc Lenain in Ken Melville’s group at SIO) with in situ temperature sensors.   The top panel shows the tide level and the arrow to the right shows the currents … Read More

Nortek Vector ADV & Aquadop ADCP (Feddersen/Guza) data posted (updated 2X)

NOTE: May 3rd 2013: The .mat files have been updated again. The format is the same as below. Some compass and sensor orientation issues have been fixed. I highly recommend you use these new versions. Download details can be found at: NOTE: .mat files have been updated as of Wed Dec 19th 10:45am PST.   Thanks to Peter Rogowski for … Read More

New River CTD+F casts

Data from CTD+F casts have now been processed.  Casts were made from a small boat on dye release days.  The CTD+F setup included a Seabird CTD and WET Labs single-channel fluorometer.  Casts were generally made from near the surface to the bed. Below is an example of mean dye and temperature profiles from 6 May, 2012. Data are now available … Read More

New River Inlet Jetski data now posted on ftp site

The jetski data from the RIVET I experiment at the New River Inlet is now posted at our ftp site.  If you do not have ftp access, please contact falk for access.  Below are two examples of the Dye and Temperature data from two days superimposed on the New River Inlet bathymetry. The listing of the ftp directory looks like: … Read More

FTP data site is now up

RIVET-ers:   our ftp data site is now up.   We are slowly in the process of putting processed and quality controlled data onto it.   To access the ftp site please ftp to or use the ftp shell program and ftp to  with username “rivet” If you would like access to the data please email falk feddersen (ffeddersen at … Read More

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
