USGS scientists load and check the mission path onto an Ecomapper autonomous underwater vehicle (AUV), while other crew members collect vertical profile information using a multiple-parameter water-quality meter. This technology is part of the

A 4" aluminum I-beam is used allow an ADVM to be raised and lowered on a stainless steel sled.

Temporary mount for installation of a horizontal ADVM under ice.  A large flange serves as a load bearing base plate with 2" pipe and pipe fittings being used to suspend the ADVM below.

Diagram depicting stationing in midsection measurement where velocity measurements are acquired. Each station width is multiplied by the station depth and measured velocity to compute the discharge in each section. Section discharges are tabulated to compute a total discharge for the cross section.

USGS scientists collect data from the surfaced Ecomapper after a mission to understand stream mixing near the Benjamin Franklin Bridge on the Delaware River in Philadelphia, Penn. This technology is part of the

Example of a camera system that will be tested to measure water level and surface velocity at the East Branch Brandywine Creek below Downingtown, PA.

A 4" aluminum I-beam is used allow an ADVM to be raised and lowered on a stainless steel sled.  The I-beam also serves as a pedestal mount for electronics housing.

Top view of beam orientation and sample volume of a sidelooking ADVM.  The ADVM-measured velocity used to index mean velocity is usually the sample volume x-component of velocity.

2" galvanzied pipe mated to a custom PVC clamp mount are used to fasten a horizontal ADVM.

Protective housing prevents damage to ADVM and allows for adjustment of heading and roll.

Old custom made Kentucky-style mount on several different boats from Kentucky and Illinois deploying both Broadband (BB) and Rio Grande ADCPs. A pole can be fixed to the mount for deploying a GPS antenna located on top of the ADCP. The Kentucky-style mount constructed of Speed Rail is recommended for Rio Grande Workhorse, RiverPro, RioPro, and Sontek M9.
