FINDING HISTORY KEY BISCAYNE MAGNETOMETER SURVEY As sub contractor for Coastal Systems International in the Key Biscayne beach renourishment project a shallow water high-resolution magnetometer survey of the proposed sand borrow areas was conducted to determine the presence of cultural submerged resources in compliance with Federal and State ordinances. SOLDIER KEY SHIPWRECK, KEY BISCAYNE, FL Sub-bottom survey of the old shipwreck located 5 miles south of Key Biscayne, FL for the National Park Service in water depths between 3 to 15 ft. Different sub-bottom anomalies were processed to create a probability distribution map of targets to locate and visualize additional shipwreck remains. ARCHAEOLOGICAL STUDIES, KEY WEST, FLORIDA The company CGS has a permit to search for underwater-submerged resources in the area of Key West, Florida. We provided sub-bottom profiler services to locate sub-bottom anomalies and generate accurate sub-bottom maps identifying the amounts of sand up to bedrock to complement their magnetometer studies in the search for a Spanish Galleon of the Atocha Fleet. SBP SURVEY OF THE MONTECRISTI SHIPWRECKS In the northern Dominican Republic. Sub-bottom survey with North Caribbean Research, using GeoCat technology, marine magnetometer and metal detector to locate shipwrecks and submerged cultural artifacts of historical value in the Montecristi area. LITTLE SALT SPRING, FLORIDA Underwater archaeological project in West Florida with Dr. John Gifford in search of buried Paleo-Indian features in the spring basin, using the RovBert, a specially modified Phantom HD2+2 ROV, marine magnetometer and metal detector. We have been involved in this continuing project since 1993. SANTA MARIA MARINA, MIAMI. FL With underwater archaeologist Dr. John Gifford. Very shallow water pre-construction bathymetric, sub bottom and metal detector survey to locate “solution holes” and investigation of magnetic anomalies in search of submerged cultural resources along the west central coast of Biscayne Bay. Used GeoCat technology, marine magnetometers and metal detectors. ACTIUM PROJECT, GREECE With Dr. Bill Murray from the University of South Florida and Dr. John Gifford from the University of Miami, conducted a Side Scan Sonar search of the waters in the vicinity of Preveza to pinpoint the location of the Actium Battle where the Roman Navy defeated Marc Anthony and Cleopatra. JUPITER WRECK, FLORIDA Sub-bottom profiler of the unidentified Spanish Galleon off Jupiter Inlet, FL. To assist in the location of Solution holes and data acquisition to visualize the debris distribution using our Geo-Cat system producing a tri-dimensional maps of sediment units. KEY WEST SPANISH GALLEON, FLORIDA CGS, Inc. has the permits to search for submerged cultural resources in the vicinity of Key West, Florida. Bert Instruments provided its sub-bottom profiler expertise to quantify and map the overburden in search of solution holes to complement their magnetic and satellite data in search of a Spanish Galleon. BROWARD COUNTY ARCHAEOLOGICAL INVESTIGATION, FLORIDA This study is part of the Broward County, Florida, beach renourishment project. Magnetic anomalies in the Broward County burrow areas and its vicinity were studied utilizing our ROV, magnetometer, metal detector and our team of underwater archaeologist divers. Each site was documented using our high-resolution ROV video camera, a hand held underwater video camera and still photography. PORT ROYAL SUNKEN CITY MAPPING, KINGSTONE, JAMAICA As part of the Port Royal Development Project, Bert Instrumentswas commissioned to map the sunken city of Port Royal, in Kingston, Jamaica, buried under the sand after the 1692 earthquake. The high-resolution sub bottom survey of the sunken city included the mapping of old structures buried in the sediment and the sub bottom survey of the proposed site for the Cruise Ship pier. The survey was done utilizing Bert Instrumentsproprietary GeoCat technology that allows the generation of high-resolution images in very shallow water. SUB-BOTTOM SURVEY OF THE MONTECRISTI SHIPWRECKS, DOMINICAN REPUBLIC In the northern Dominican Republic. Sub-bottom survey with North Caribbean Research, using GeoCat technology, marine magnetometer and metal detector to locate shipwrecks and submerged cultural artifacts of historical value in the Montecristi area. HERNANDO ARCHAEOLOGICAL BEACH MULTI-SENSOR SURVEY, FLORIDA As part of the archaeological studies prior to the modifications to the Hernando Beach Channel, Bert Instruments was awarded the contract for a multi sensor survey of the existing channel and the proposed area for the new channel in a water depth varying between 2 ft. to 6 ft. A combination of precision fathometer, high sensitivity magnetometer, GeoCat sub bottom profiling system and precise satellite positioning was utilized with all the instruments acquiring data simultaneously with real time offsets to log always at the same geographical position in spite of the geometry of the array of instruments utilized. © BERT INSTRUMENTS
