Pieces ranged from 50x20x20 cm to 5 cm dia. RD68-2 - 3 buckets Mn nodules from 5 cm dia. to 30cm. Cores are basalt, limestone or green hyaloclastite(?) fragments 1cm to 5cm. The largest core is 2x5x5 cm. 2 buckets of pieces from the largest nodules was discarded. RD68-3 - 4 buckets of green hyaloclastite and/or pumaceous tuft.
