Remote Sensing
Remote sensing investigations conducted by Tidewater Atlantic Research are designed in accordance with project specific research requirements and are carried out in accordance with criteria established by Section 106 of the National Preservation Act of 1966 (36 CFR 800), the Abandoned Shipwreck Act Guidelines (Federal Register 1990) and the Secretary of the Interior’s Standards and Guidelines for Archaeology and Historic Preservation (1984). The nature and intensity of survey level reconnaissance is determined by the potential for archaeological resources, historical significance of the survey area and nature and level of proposed project activities as identified by literature and records research and consultation with individuals and representatives of organizations associated with the proposed project.

Tidewater Atlantic Research personnel are proficient in the use of state-of-the-art equipment for the conduct of investigations ranging from small remote sensing operations to large multi-component investigations. Equipment packages include proton procession and cesium magnetometers, digital and analog side scan sonars, sub-bottom profilers, precision echo sounders, differential global positioning systems, Pentium-based computers and HYPACK navigational software. All surveys are conducted from research vessels suitable for operations in the project area environment and are equipped with all required safety features, first aid supplies, EPIRB and VHF communications equipment.

Data analyses are conducted in accordance with project requirements and are based on models developed in association with documented diagnostic characteristics. End products include a thorough treatment of methodologies employed, detailed analysis of target signatures with appropriate contour maps and options for avoidance and/or additional investigation of all identified potentially significant cultural resources.

Contour maps are used to identify targets that may or may not represent cultural resources.
