The Hobby LicenseĪlso does not permit use of tools, digging, or movement of sediment to expose and Recovery of embedded material, including articulated fossil specimens. This license does not allow disturbance or recovery of hardware and structural componentsįrom shipwrecks or submerged historic structures, nor does it allow disturbance or That they can see resting on the bottom sediments on submerged sites in state waters. The Hobby License allows hand collection of naturally exposed artifacts and fossils Recovered in accordance with the Underwater Antiquities Act and license contract. In exchange for reporting detailed information about any artifactsĪnd fossils collected, Hobby License participants are granted title to submerged finds Responsible collection activity and reporting of any property recovered from submerged Similar to many fish and wildlife licenses, the conditions of the Hobby License require Thousands of sport divers and avocational collectors have been able to play an activeĪnd ongoing role in the documentation and management of our state's submerged cultural Since the Hobby License program's inception in the 1970s, In state waters by individuals licensed through the South Carolina Institute of ArchaeologyĪnd Anthropology (SCIAA). In an effort to preserve and protect the Palmetto State's vast underwater archaeologicalĪnd paleontological legacy, the South Carolina Underwater Antiquities Act permits small-scale, recreational, non-mechanical, non-commercial surface collecting South Carolina Underwater Antiquities Act.SC Institute for Archeology and Anthropology.If a transducer is lost or severely damaged, a replacement or repair fee is charged. Normally, the loan fee provides for shipping costs, 30 meters of underwater electrical cable, a standard calibration (free-field voltage sensitivity and/or typical transmitting response), and minor repair or maintenance of a transducer. The full amount of the loan fee must be received prior to shipment of a transducer. USRD charges a loan fee for use of transducers in order to recover incurred costs. For general guidance, refer to the chart of transducer specifications below. Based on this information, the USRD staff can help select an appropriate transducer. ![]() The intended use, the measurement environment, and the frequency range of interest determine the type of transducer that is best suited to the application. ![]() Once authorized, loans to foreign governments are treated the same as loans to U.S. government and 55% of these customers are from commercial industry, universities, and state governments. Approximately 45% of the customers for these transducers are from various parts of the U.S. USRD transducer standards are used to verify specifications, to show conformance with contractual obligations, to show conformance with environmental laws, and to provide a reference base for advancing science and technology within the underwater acoustics community. with a wide variety of underwater transducer standards. Consistent with this role, USRD provides the U.S. The Underwater Sound Reference Division (USRD) at the Naval Undersea Warfare Center (NUWC) in Newport, Rhode Island performs as the equivalent to NIST in underwater acoustics with traceability to NIST electrical voltage and current standards. The National Institute of Standards and Technology (NIST) performs the governmental function of providing standards in areas except underwater sound. The impetus for this effort is to ensure consistent and accurate measurements for research, development, inspection, acceptance and maintenance of ships, aircraft, and weapon systems. Navy's policy to maintain acoustic standards of measurement to certify performance of test and measuring equipment. ![]()
