Given the minimal overlap at Site 1099, correlating Hole 1099A with Hole 1099B should have been a simple task. Unfortunately, the upper 5 m of core from Hole 1099B has numerous small gas voids and the upper 70 cm is water saturated with a very soupy interval from 52 to 66 cm. The soupy interval produces large anomalies in several of the data sets, particularly in color reflectance parameters a* and b*. Any correlation should, therefore, avoid using at least interval 178-1099B-1H-1, 0-70 cm.
We found that none of the data examined from the upper part of Hole 1099B, which includes magnetic susceptibility, GRA density, and color reflectance (L*, a*, and b*), appears to correlate well with data from the lower few meters of Hole 1099A. One of the better correlations, though not convincing by any means, is obtained from the color reflectance parameter b* data with no depth offset for Hole 1099B relative to Hole 1099A. Given our inability to find any convincing anomalies that suggest that a depth shift was required, we consider the best composite depth scale to be that obtained by using the mbsf scale already available.
In the overlap region, the best splice is then obtained using data from Hole 1099A because there is little or no coring disturbance as opposed to the disturbance visible in the upper 5 m of Hole 1099B.
