Description:
The interstitial water received at UCLA from Leg 7 (Guam to Hawaii) consisted of forty-two samples of approximately 5 milliliters each, three samples of approximately 10 milliliters each, and three samples of approximately 100 milliliters each. These pore waters had been squeezed from sediments consisting primarily of biogenic ooze, and had been collected at five different drilling sites along the route. High cobalt value were observed at Site 66 and were accompanied by a relatively high manganese concentration, but more normal iron, nickel and copper concentrations. This apparent cobalt enrichment could not be explained at the time of procedure. The line Islands area were Site 66 is situated was later notoriously known for its high Co values in manganese crust deposits (see, He, G., Ma, W., Song, C., Yang, S., Zhu, B., Yao, H., Jiang, X., Cheng, Y., 2011. Distribution characteristics of seamount cobalt-rich ferromanganese crusts and the determination of the size of areas for exploration and exploitation.
