Field Activity 1982-034-FA

Identifier 1982-034-FA
Alternate names GYRE 82-11; 11-G-82; 82-G-11
Purpose 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.
Location Blake Plateau, United States, North America, North Atlantic;
Summary Camera lowerings - Approx. 45 hrs. and 18,000 photos; High-resolution acoustic profiling: 1000 km; MFES profiling: 100 km; Bottom reflection lowerings: 3; Bottom refraction experiment: 1; Dredges: 18 (300 kg rocks recovered); Cores: 11.
Info derived Samples and chemical analysis;
