Core expansion in recovered deep-sea sediment cores occurs because of pressure release, degassing, and elastic rebound (Moran, 1997). This can lead to core sections overlapping at core breaks and can cause apparently duplicate measurements when using the original mbsf depth scale. We constructed a revised mbsf (rmbsf) scale for Hole 1202B to avoid overlapping measurements by adding a constant offset to each core (Table T1). Conversion between the two depth scales is straightforward and requires addition of the offset constant to the mbsf scale or subtraction from the rmbsf scale.
