Description | United States Geological Survey, Menlo Park, California,Scripps Institution of Oceanography,Korea Institute of Geology, Mining, and Materials, Taejon, Korea,Scottish Universities Research and Reactor Centre, Kilbride, UK. Chief Scientists: Jim Hein, Hubert Staudigel. Geological data (dredge, bathymetry) of field activity W-6-91-WP in Northwest Pacific from 10/31/1991 to 12/02/1991 | ||||||||
Location | Northwest Pacific | ||||||||
Summary | physical data holdings 13 NW Pacific seamounts and guyots were dredged during the Tunes 6 cruise. A total of 35 dredges were attempted and 23 recovered Fe-Mn crust samples and substrate rock. One or two dredge hauls recovedred samples from most guyots, however, Vlinder and Batiza Guyots yielded five and four dredge haul recoveries, respectively. Minor additional bathymetric surveys were conducted during Tunes 6. | ||||||||
Info derived | Sample descriptions, detailed chemical and mineralogical analyses of bulk Fe-Mn crusts and individual crust layers, and major oxide compositions and mineralogy for substrate rocks. | ||||||||
