Area of Operations: Blake Plateau, United States, North America, North Atlantic
Dates: September 18, 1982 to September 28, 1982
Chief scientist: Frank Manheim
Objectives: Test new techniques to determine thickness, distribution and quality of mineral deposits on the Blake Plateau with special reference to manganese nodules and manganese-phosphate pavements; obtain ANGUS/ARGUS wide-angle bottom photos for visual ground truthing; collect pavement core samples; determine nodule concentration via MFES; and determine mineral thickness via seismic reflection/refraction.
Type of Activity: Sampling; Photography; Reflection/refraction profiling;Reflection/refraction profiling
