Day 28 - August 18, 2013


This day was spent dredging two spots on the South side of Tuscarora Bank.  The Westernmost of the two (nicknamed Betchup) brought up several types of basalts and volcanic breccias with Mn crust or as cores to Mn nodules. The more central dredge brought up very few samples, only one of which volcanic: interestingly, it was a small piece of volcanic spatter, potentially a sign of subaerial eruption.
