Mass physical properties of surface sediments in the KODOS(KR5) area, northeast equatorial Pacific

Abstract

Sea floor sediment have been extensively studied to understand the correlation of mass physical properties and sedimentological process in the Clarion-Clipperton fracture zone of northeast equatorial Pacific. Within the past twenty years sediment characters such as sediment types and ages, bioturbation, porewater nutrients, mineralogical and chemical compositions, and mass physical properties were broadly analyzed in the Korea deep ocean study (KODOS) area. However the geological and geophysical survey was recently concentrated on the KR5 block, formerly B2. The objective of this study is to show the textural parameters and mass physical properties of surface sediments intensively in the KR5 area.
