Various ratios of C1-C5 hydrocarbons, gas composition and computed temperature at DSDP Leg 64 Holes

I have evaluated shipboard data and preliminary interpretations related to organic geochemistry in light of additional shore-based analyses. Data on interstitial gas, the C/N ratio, and fluorescence indicate that organic matter was altered by sills and that these were all single intrusions except the upper sill complex at Site 481, which was a multiple emplacement. Site 477 had the highest in situ temperature, estimated from interstitial gas composition to be 225°C.

Single planktonic foraminiferal Mg/Ca ratios of samples from sediment trap CBi3 upper off Cape Blanc (NW-Africa)

The data shows Mg/Ca ratios of single specimens of the planktonic foraminifera Globigerinoides ruber (pink and white variety) and Globorotalia Inflata from a sediment trap anchored off Cape Blanc (NW-Africa). Mg/Ca ratios were determined on an ICP-MS and ICP-OES at the University of Bremen, after flow-through cleaning. Additionally, shells sizes and calculated shell weights are provided.
