recognized events are: (1) a pronounced increase in decompacted sedimentation rate in the Celebes Sea at 23.4 Ma, indicating basin transformation from a larger, more open oceanic setting to a marginal basin; (2) an increased basement subsidence rate in both basins between 10.8 and 8.9 Ma associated with the initiation of the Sulu Trough and the ...

Overview. Sed rate, or erythrocyte sedimentation rate (ESR), is a blood test that can show inflammatory activity in the body. Many health problems can cause a sed rate test result to be outside the standard range. A sed rate test is often used with other tests to help your health care team diagnose or check the progress of an inflammatory disease.

Sedimentation Rate. Sedimentation rates were calculated using ages described above and decompacted sediment thicknesses. Decompaction was based on porosities measured using the "moisture and density" technique on discrete 6 cm 3 samples spaced at ~1.5 m on cores from Hole M0079A. The wet and dry masses of these samples …

Thus, for SGR with a vertical resolution of 15–20 cm and a mean sedimentation rate of 30 cm/ka, a time resolution of c. 1.0–1.3 ka can be achieved. Sedimentation rate variations for the recorded data can be detected using the sliding window method (Molinie and Ogg 1990b; Wonik 2001). The spectral analysis is …

SEDIMENTATION RATES. The distribution of ages and sediment thicknesses allows the calculation of sedimentation rates for lithologic Units I and IV (see "Unit I" and "Unit IV").Although the sedimentary section has not been decompacted, some patterns have been observed (Fig. F67).Sedimentation rate reconstruction in the upper 108.7 mbsf is …
