Radiolarians from ODP Leg 116 holes

Cores recovered from three sites of Leg 116 were studied for radiolarians. Generally, radiolarians were absent from most samples prepared for examination. Moderate to well-preserved radiolarian assemblages are found only in the uppermost one or two cores that were the focus of this study. All of the radiolarian assemblages in the upper cores belong to the Buccinosphaera invaginata Zone of latest Quaternary age. However, there is one stratum where a few Miocene radiolarians are reworked into the modern assemblages. Local seamounts are suggested sources for the reworked radiolarians.

Geochemistry of interstitial waters from ODP Leg 115 sites

As a part of the shipboard scientific program, interstitial waters were routinely analyzed for pH, alkalinity, salinity, chlorinity, calcium, and magnesium during Leg 116. Unfortunately, the tables containing these data for Sites 718 and 719 were inadvertently omitted from the Initial Results volume (Cochran, Stow et al., 1989, doi:10.2973/odp.proc.ir.116.1989). The missing data are presented here (Tables 1-3) along with the Site 717 data, reproduced for completeness.
