Affiliated Researchers collected sediment samples using vibracore methods, and conducted bathymetric surveying and sub-bottom profiling at Black River in Lorain County, Ohio.  The environments at Black River are being restored with funding from the USEPA, USFWS, NOAA, GLRI, ARRA, State of Ohio, and other sources.  Affiliated Researchers’ services were a necessary part of this environmental restoration program.

Affiliated Researchers utilized its 20’ pontoon vibracore vessel, RTK-GPS survey equipment, and a Rossfelder P3 vibracore system to collect 8’ long sediment cores from the river bed.   Affiliated Researchers utilized its 16’ Alumaweld survey vessel, RTK-GPS survey equipment, and Knudsen 3212 dual-frequency echo-sounder to conduct bathymetric surveying and sub-bottom profiling, to enable an accurate survey of the river bed as well as the various sediment layers beneath the river bed.

Affiliated Researchers utilized its RTK-GPS survey equipment and OPUS methods to establish several, NGS verified benchmarks at the project location.  Affiliated Researchers setup a RTK-GPS “base station” at one of the benchmarks to transmit highly-accurate, real-time GPS corrections to its RTK-GPS survey equipment onboard the vibracore and survey vessel.

Since 1990, Affiliated Researchers has become a recognized leader in providing high quality environmental and technical services for municipalities, public utilities, environmental-engineering firms, Fortune 500 companies, energy companies, and the State and Federal agencies to include the DOD, NOAA, USACE, USCG, USEPA, and USFS.

Affiliated Researchers provides its services nationwide.  Please contact our specialists to discuss your project requirements.
