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

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.

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

Today was the first day of the SIO (Feddersen/Guza) drifter releases.    We did 3 set of 2hr+ drifter releases with our 35 drifter fleet.    The first release began at about 0830 as the tide began to ebb.      We released the 35 drifters near channel marker 08 but in slightly different cross-channel positions – see the screenshot image below … Read More

Airborne operations are underway at RIVET. Below are some photographs of the inlet from the APL-UW test flight on Monday (17:00 – 18:00 local time). Onboard the Cessna 172, we have a dual-beam along-track interferometric synthetic aperture radar, two infrared cameras, and a visible wavelength camera. We will be posting imagery from these sensors as soon as it is available.

Here are example merged Argus products that we will be putting on the web. If you have suggestions for changes, let us know. For example, we will add instrument locations as we learn them. The first is a large area time exposure showing the shoal configuration. The second in a small area snap that shows fierce crossing wave patterns.
