FiGurE 15.—Distribution of barium and the barium-to-aluminum ratio in four areas where the introduction of drilling mud 
was not expected. Analyses were performed on the fine fraction of sediment. Stations 2 (M10-02-00-JX) and 3 (M11-03-00- 
AX) were sampled with a grab sampler. Samples OC140-8B and 83G9-B were collected with a hydraulically damped gravity 
corer and a box corer, respectively.
