MidPacific Seamount. Eight buckets of samples labeled 1-5 available.
1 :   
Comments: 250 lbs (115 kgs) in five bags + lab samples. North side of seamount dredged. Hey, we got some real neat stuff. Dredge bag dragged up northeast side of seamount from 1835 m water depth to 1700 m. Reflection records reveal reef complex capped by pelagic sediments atop seamount. No volcanics, Mn- encrusted limestone made up entire dredge. Cretaceous reef complex - indicated by presence of rudist. fragments. Benthonic forams, other mollusks, coral fragments also contained within rocks. Also present in dredge were a few samples of pelagic limestone, age unknown.
