Abstract

Three zones of the sediment column are discussed separately because of the different processes involved in causing concentration changes: 1. The upper few hundreds of meters: In this zone, characterized by very high sedimentation rates (>1200 m/m.y.), interstitial waters show very sharp increases in alkalinity, ammonia, iodide, bromide, YS, and LIF; 2. Whereas below 200 mbsf concentration gradients all show a decreasing trend, the zone at ~365 mbsf is characterized by concentration reversals; 3. The decollement zone (945-964 mbsf) is characterized by concentration anomalies in various constituents (bromide, boron, δ11B, manganese, LIF). -from Authors
