Tropical Atlantic ODP1260 Cretaceous Calcareous Nannofossil Data Blair, S.A. Blair, S.A. biogeography earth science/paleoclimate/paleocean (ODP1260>LATITUDE 9.2658>LONGITUDE -54.5439) Records of past climate and ocean circulation derived from marine sediments. Parameter keywords describe what was measured in this data set. Additional summary information can be found in the abstracts of papers listed in the data set citations. STUDY NOTES: Calcareous nannofossil abundances estimated from smear slide counts of middle Cenomanian to late Turonian age (~95 - 88 Million Years BP) from Ocean Drilling Program Leg 207, Site 1260. This dataset was used to constrain nannofossil biostratigraphic events for this time period as well as analyze nannofossil assemblage fluctuations across OAE 2 at the Cenomanian/Turonian boundary. Raw abundance counts of 500 were made on an Axioskop2 microscope and converted to percent abundance (relative to 100% of the total nannofossil populatio NCDC-Paleoclimatology https://www.ncdc.noaa.gov/data-access/paleoclimatology-data - Bauer Bruce Investigator : Blair, S.A. 2010-10-08 ONLINE Files online, ASCII https://www.ncdc.noaa.gov/paleo/study/9740 https://www1.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/blair2011/blair2011.txt https://www1.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/blair2011/blair2011.xls https://www1.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/blair2011/blair2011.txt https://www1.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/blair2011/blair2011.xls English https://www.ncdc.noaa.gov/paleo/study/9740 https://www1.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/blair2011/blair2011.txt https://www1.ncdc.noaa.gov/pub/data/paleo/contributions_by_author/blair2011/blair2011.xls Blair, S.A., 2011.
