Description: This includes seismic and side scan tracklines from 1985-2012. Research and processing method vary throughout the years: Seismic Tracks 1985 - Tracklines from seismic reflection profiles - Datasonics 3.5 kHz Ore Geopulse 280j. This work was associated with cooperative agreement 14-12-001-30316 between Maryland Geological Survey and the Bureau of Economic Geology University of Texas at Austin as agent for Branch of Geologic and Geophysical Studies Minerals Management Survice Reston, VA (Brooks, 1988). REFS: Brooks, J.R. 1988. Sieve Analyses and Heavy Mineral Concentrations of the Sand Portions of Cores Taken from the Inner Continental Shelf of Maryland. Maryland Geological Survey, Baltimore MD. Seismic Tracks 1987 - Tracklines from seismic reflection profiles - Datasonics 3.5 kHz Ore Geopulse 280j. REFS: Toscano, M.A., Kerhin, R.T., York, L.L., Cronin, T.M., and S.J. Williams. 1989. Quaternary Stratigraphy of the Inner Continental Shelf of Maryland. Report of Investigations #50, Maryland Geological Survey. Seismic Tracks 1992 - Datasonics acoustic profiling system 3.5 kHz.

Offshore Sand Resources in Northern Maryland Shoal Fields. Coastal and Estuarine Geology File Report #94-8 Seismic Tracks 1993 - Data was collected during an August 1993 survey, Datasonics acoustic profiling system 3.5 kHz. the Calcomp 9800 large format digitizer was used to enter seismic data into AutoCAD 12 DOS. Civil/Survey (Softdesk) within AutoCAD was used to generate the surface models. This method used TINS (triangular irregular networks), the most commonly employed method in 1993. The data is developed and generated under the Maryland Geological Survey/Delaward Geological Survey Cooperative agreement, a grant funded by the Minerals Management Service. REFS: Conkwright R.D., and R.A. Gast. 1994, "Potential Offshore Sand Resources in Central Maryland Shoal Fields" Coastal and Estuarine Geology File Report #94-9 Seismic Tracks 1994 - Datasonics acoustic profiling system 3.5 kHz. the Calcomp 9800 large format digitizer was used to enter seismic data into AutoCAD 12 DOS. Civil/Survey (Softdesk) within AutoCAD was used to generate the surface models. This method used TINS (triangular irregular networks), the most commonly employed method in 1994. The data is developed and generated under the Maryland Geological Survey/Delaward Geological Survey Cooperative agreement, a grant funded by the Minerals Management Service. Data collected onboard the R.V. Discovery in August 1994. REFS: Conkwright R., and Gast R., October 1994, "Potential Offshore Sand Resources in Central Maryland Shoal Fields" Seismic Tracks 1995 - Datasonics acoustic profiling sisyem 3.5 kHz. the Calcomp 9800 large format digitizer was used to enter seismic data into AutoCAD 12 DOS. Civil/Survey (Softdesk) within AutoCAD was used to generate the surface models. This method used TINS (triangular irregular networks), the most commonly employed method in 1995. The data is developed and generated under the Maryland Geological Survey/Delaward Geological Survey Cooperative agreement, a grant funded by the Minerals Management Service. (exact dates and references for this set of tracklines cannot be found. It is known that the above listed technology was being used at the time). These are the tracklines for Charlene Shoal 1995.
