5/4/2012 REMUS River Plume Survey (No Dye Release)

First ever blog post for me.  The ‘other’ Scripps group has been running the REMUS AUV to characterize inlet dynamics and map the outgoing plume.  Before the dye surveys, we ran a series of missions to survey the naturally occuring optical signals leaving the inlet over an outgoing tide.  Above are cross-sections of CDOM across 4 different transects.  We’ve also … Read More

NRL ATI-SAR Imagery of the New River Inlet

After arriving on Monday, our NRL SAR crew flew on Tuesday, Wednesday, and Friday of this week. Apart from some drama before the first flight (resolved with a 300-foot daisy chain of extension cords across the airport tarmac), we’ve had no major hardware issues and have enjoyed excellent SAR collection conditions: decent surface winds to roughen the water, but smooth flying at 2900′. Smooth … Read More

West Side Bedforms

Attached is a higher resolution local merged timex from today’s low tide showing detailed bedforms on the western side of the inlet.  I’m amazed by the amount of structure.  Also, we have posted a first draft web description of Argus at RIVET at cil-www.oce.orst.edu/rivet.  It includes description of our geometry set up procedure and the location of a decent 3D … Read More

APL-UW SAR imagery of the New River Inlet

The image below is an overlay of a SAR intensity image recorded by the APL-UW dual-beam along-track interferometric microASAR system (the microASAR units are developed by Artemis, Inc., http://artemisinc.net). This data was recorded on May 2 at 11:55 EDT during the low tide. A Google Earth version of this image (KMZ file) can be downloaded from http://herschel.apl.washington.edu/darla/RADAR/SAR/SNAPSHOTS/uASAR_05022012_115500CH1_image532376_-9.kmz. The width of … Read More

Day 3 of Drifter Releases

Yesterday (May 3rd) was the 3rd day of SIO drifter releases.     It was quite interesting.  We released again on an ebb tide near channel marker 8.  This time we released drifters in pairs (except for the last 3) separated by 1 minute.  With 33 drifters it took 17 minutes.   The reason for time separation was to see how that might … Read More

Traykovski WHOI Quadpod deployment

Yesterday (May 2nd) we deployed two quadpods in the old and new channel (near the outer most red can channel marker #4) at the locations in the linked kml These are 7′ tall frames that have the upper ~2 exposed at low tide and are submerged by ~2′ at high tide. They have various downward aimed sensors to measure flow, … Read More

Radar snap of waves

This is an example radar image showing crossing wave trains on the shoal that extends from the south side of the inlet. We are analyzing these image sequences to see how well (or not) wave directions can be extracted and bathymetry estimated. Hope to have more soon.

Merge Images available

I’m not sure if this is well known yet, but Argus merged images are available on the web at http://cil-www.oce.orst.edu/RIVETmerge.  They are posted as they are collected and consist of snap, timex, var, bright and dark images for every 1/2 hour.  The upper half of the page is rectifications for the large inlet area at 2.5 m resolution.  If you … Read More
