Hathaway, U.S. Army Engineer Research and Development Center originator Stan Boc, U.S. Army Engineer Research and Development Center originator Field data collection was conducted for the U.S. Army Engineer District, Pacific Ocean, Honolulu (POH), during August 9 - September 14, 2005, off Kailua, Lanikai, and Waimanalo, Oahu, Hawaii. Wave and current data were collected at five fixed locations using bottom-mounted RD Instruments Workhorse, 1.2 MHz, ADCPs (Acoustic Doppler Current Profilers) and Sontek Hydra ADVs (Acoustic Doppler Velocimeters). The ADCPs include wave measurements. Four inexpensive current drogues (drifters) were designed and built at the CHL Field Research Facility (FRF) that used GPS tracking and radio telemetry for positioning. Deployments were made on 10 August and 13 September. June. Learn of current and wave patterns in the bay for design considerations.

Figure 2 (report) shows the custom built mount that was held to the bottom with about 80 lbs of lead weight. These gauges have four acoustic transducers for measuring currents and a pressure sensor, from which horizontal and vertical current profiles were computed at 0.2 m vertical spacing. These units sampled at 2 Hz for directional wave measurements. Each hourly wave burst was approximately 34 minute long, starting at the top of each hour, and consisted of 4096 points. There is a 0.44 m blanking distance from the transducer head, and with a 0.2 m bin width this makes the first sample 0.72 m past the transducer, or about 1.12 m off the bottom. Current profiles were collected every 10 minutes from a 200 point average. Deployments were on 9 Aug 2005 and retrieved on 14 Sep 2005. ADCP-2 was reprogrammed on 10 Aug so collection started a day later, and the batteries were depleted on 4 Sep, about 10 days before retrieval of the other gages. ADV Gauges: The three ADV gages were the Sontek's Hydra model that sample a single point current velocity (U, V, and W) and contained an external pressure sensor. The instrument frame and ADV transducer are shown in Figure 3 ( report, after gauge retrieval). The sample volume for the current measurement is approximately 1-2 cm in size and about 0.17 m from the center transducer. This unit uses three beams to determine the three current components. Current Drogues: Four inexpensive current drogues (drifters) were designed and built at the CHL Field Research Facility (FRF) that used GPS tracking and radio telemetry for positioning. They were constructed with off the shelf plumbing supplies (PVC pipe, vertical risers, rubber unions, hose clamps), a Garmin Geko GPS receivers, and MaxStream (model XStream-PKG-R) radio modems (Figure 4, report). The sails had about a one meter cross-section. The lower vertical PCV pipe (submerged) contained the modem and batteries, the upper horizontal pipe contained the GPS receiver and radio antennas. A NEMA GPS data string was transmitted once per second and the Garmin GCP unit internally recorded positions every 30 seconds. These GPS units are WAAS enabled and should have a horizontal accuracy of about 3 m. The radio tracking was partially successful- it required line of sight which was not possible to simultaneously receive drifters in the Kailua and Waimanalo Bays. Also the antennas and connectors should be more robust, two broke during deployment.
