Depth of first appearance

Cesium-137 is an impulse marker where the subsurface peak of maximum activity (or first appearance of activity) is used to measure accumulation rates. However, the resolution of this peak and depth of first appearance can be altered by physical and biological mixing processes. Feeding activities of benthic... [Pg.172]

Shoaled Interface. A second controversial observation was the suggestion that the oxic-anoxic interface had shoaled. When the 1988 data were compared with some earlier data [e.g., Atlantis II, 1969 (24) Chain, 1975 (16)] from the same location, it appeared that the depth of first appearance of sulfide had become shallower (15). It also appeared that the salinity in the upper pycnocline had increased since 1969. [Pg.163]
