Releasing the Workhorse II ADCP

Fri, 31 Mar 2023 14:52:54 GMT

RD Instruments’ Workhorse—the most sold ADCP in the world— just got better. We’ve enabled new features and even better performance across more applications and demanding environments with the Workhorse II. RDI’s proven MEMS heading and tilt sensors with 1° RMS heading accuracy at up to ±70 tilt offer superior performance at the highest latitudes. Raw magnetic data can be logged, and the new software makes post‐deployment heading corrections a breeze. Workhorse II also offers: A highly robust metal shell connector; 16 GB compact flash memory; and new intuitive planning software.

With the direct‐reading Monitor, self‐contained Sentinel, and vessel‐mounted Mariner configurations, the Workhorse II is among the most versatile and capable ADCP platforms. Bottom tracking, directional waves, high-resolution, LADCP, and ice‐tracking modes are available on any model, making any model capable of interdisciplinary use. And original Workhorses can receive Workhorse II upgrades for many more years of successful deployments.

Measuring Extreme Nearshore Storm Waves Off the Irish Coast

Thu, 04 Jun 2020 14:26:23 GMT

Professor Dias will present a statistical analysis of nearshore waves observed during two major North–East Atlantic storms in 2015 and 2017. Surface elevations were measured with a 5-beam acoustic Doppler current profiler (ADCP) at relatively shallow waters off the west coast of Ireland. To compensate for the significant variability of both sea states in time, a novel approach was used for analyzing the non-stationary surface-elevation series. The distributions of crest and wave heights are compared with theoretical predictions based on the Forristall, Tayfun and Boccotti models. In particular, the latter two models have been largely applied to and validated for deep-water waves. Profession Dias will show that they also describe well the characteristics of waves observed in relatively shallow waters.

Webinar Wednesday: Smaller Sonars that Pack a Punch: Phased Array ADCPs and DVLs

Wed, 27 May 2020 17:38:59 GMT

Join us for this Webinar Wednesday, where we'll take a deep dive into what Phased Array technology is, and what it can deliver.

Teledyne RD Instruments 2D Phased Array technology has pushed back the practical, mechanical limits for transducer size and frequency at both ends of the size continuum. This expands the scope of ADCP and DVL performance and widens our range of configurations while still making four different measurements simultaneously-- two from an acoustic pulse profiling the water column (velocity profile, echo intensity profile), and two from a bottom-tracking (BT) pulse (velocity over bottom, altitude above bottom). In this session, we consider measurement capabilities using Teledyne RDI’s 2-d Phased Array technology.

Use of Acoustic Techniques for the Determination of Net Sediment Transport...

Tue, 05 Dec 2017 09:33:21 GMT

Presenter:

David Williams
Australian Institute of Marine Science

Abstract

The Marine Supply Base channel in Darwin Harbour, Northern Territory Australia provides access to berthing and loading at East Arm wharf for vessels that support the offshore energy industry.

Sedimentation in the channel due to complex currents in the area is reducing navigational efficiency and safety.

A combination of multi-beam echo sounder, utilising an Odom MB1 and Acoustic Doppler Current Profiler, using a network of TRDI Workshorse and Sentinel V, surveys were conducted over a 12 month period encompassing both dry and wet seasons. The MBES surveys mapped the extent of the MSB channel and the East Arm sandbar adjacent to the channel. Tidal current patterns determined from the ADCP surveys show that tidal currents in the area are highly variable and are stronger in the ebb tide direction except at the entrance to the navigation channel. Tidal current are more variable in the flood tide direction at all remaining sites along the channel. The strength and direction of the tidal currents indicate that sediment movement is along the channel toward the deeper seaward navigation channel.

Fine sediments have deposited in the MSB berthing area slightly reducing the volume of the berthing pocket and also depositing toward the end of the channel. An annual sediment deposition rate of 100 mm over the berth area was determined via observations and modelling.

Non-cohesive sand transport modelling, configured using data from the MBES and ADCP surveys, has indicated slow movement of the sandbar in a dominantly south west direction at between 100 – 200 mm per month. Fine sediment modelling indicates deposition in the MSB berth area of 20 – 50 mm/year under average conditions.

Modelling indicates that if the MSB channel was realigned to be straighter the current directions would be more regular assisting navigation. Sediment accumulation would not present a major issue if the majority of the East Arm sandbar was dredged.

Discharge measurements in fish passage

Mon, 06 Jun 2016 02:00:00 GMT

In the river Mosel, a hydroelectric plant is situated near the city of Koblenz. Alongside the plant, a fish passage is present. The presence of the fish passage results in an extra channel through which river discharge can be transported. The Bundesanstalt für Wasserbau (BAW) has requested Aqua Vision to quantify the discharges in the fish passage and in the channels connected to the fish passage. In July 2015 and March 2016, Aqua Vision has deployed three horizontal ADCPs over a three day period at fixed locations in the fish passage. A large number of calibration transects have carried out by use of two StreamPro ADCPs.
