Data Report: Stable Isotope Ratios of Foraminifers from ODP Leg 207, Sites 1257, 1258, and 1260, and a Cleaning Procedure for Foraminifers in Organic-Rich Shales. In Mosher, D.C., Erbacher, J., and Malone, M.J. (Eds.) Proceedings of the Ocean Drilling Program, Scientific Results Volume 207. http://www-odp.tamu.edu/publications/207_SR/104/104.htm ABSTRACT: We report oxygen and carbon stable isotope analyses of foraminifers, primarily planktonic, sampled at low resolution in the Cretaceous and Paleogene sections from Sites 1257, 1258, and 1260. Data from two samples from Site 1259 are also reported. The very low resolution of the data only allows us to detect climate-driven isotopic events on the timescale of more than 500 k.y. A several million-year-long interval of overall increase in planktonic d18O is seen in the Cenomanian at Site 1260. Before and after this interval, foraminifers from Cenomanian and Turonian black shales have d18O values in the range –4.2 per mil to –5.0 per mil,suggestive of upper ocean temperatures higher than modern tropical values. The d18O values of upper ocean dwelling Paleogene planktonics exhibit a long-term increase from the early Eocene to the middle Eocene. During shipboard and postcruise processing, it proved difficult to extract well-preserved foraminifer tests from black shales by conventional techniques. Here, we report results of a test of procedures for cleaning foraminifers in Cretaceous organic-rich mudstone sediments using various combinations of soaking in bleach, Calgon/hydrogen peroxide, or Cascade, accompanied by drying, repeat soaking, or sonication. A procedure that used 100% bleach, no detergent, and no sonication yielded the largest number of clean, whole individual foraminifers with the shortest preparation time. We found no significant difference in d18O or d13C values among sets of multiple samples of the planktonic foraminifer Whiteinella baltica extracted following each cleaning procedure.

Data from two samples from Site 1259 are also reported. Samples of carbonate sediments (one per core) were taken in the shipboard sediment laboratory. At Woods Hole Oceanographic Institution (USA), these samples were oven-dried, gently crushed, soaked for 2 hr in a 3% Calgon-hydrogen peroxide solution, and washed over a 63-u­m sieve with warm tap water (pH = 6). Wet samples were dried in an oven at 45°C for 2 hr. Cretaceous organic-rich mudstone (black shale) samples were cut from core on the JOIDES Resolution catwalk and frozen shipboard at -80°C. Black shale samples were later freeze dried and partly crushed using a porcelain mortar and pestle. Crushed black shale sediments were soaked in undiluted Clorox bleach for 2 hr, washed, and dried, and then soaked for 1 hr in undiluted bleach, washed and dried. For planktonics, single species stable isotope analyses were made of 1 to 25 individual whole specimens. For benthics, 1 to 5 individuals of single species or mixed species were analyzed. Oxygen and carbon isotope ratios were measured on a Finnigan MAT 252 mass spectrometer with an automated Kiel carbonate device at Woods Hole Oceanographic Institution. Instrument precision is +/-0.07 per mil for d18O and +/-0.03 per mil for d13C. Results are reported relative to the Vienna Pee dee belemnite (PDB) isotope standard. Site 1257 9° 27'N 54° 21'W 2951m.
