Maastrichtian Foraminiferal Stable Isotope DataEntry ID: NOAA_NCDC_PALEO_2002-036
Abstract: A global compilation of deep-sea isotopic records suggests that Maastrichtian
ocean-climate evolution was tectonically driven. During the early
Maastrichtian, the Atlantic intermediate-deep ocean was isolated from the
Pacific, Indian, and Southern oceans; deep-water formed in the high-latitude
North Atlantic and North Pacific. At the early/late Maastrichtian boundary, a
major reorganization ... of oceanic circulation patterns occurred, resulting in
the development of a thermohaline circulation system similar to that of the
modern oceans. A combination of isotopic and plate kinematic data suggest that
this event was triggered by the final breaching of tectonic sills in the South
Atlantic and the initiation of north-south flow of intermediate- and
deep-water in the Atlantic. The onset of Laramide tectonism during the mid
Maastrichtian led to the concurrent draining of major epicontinental seaways.
Together, these events caused cooling, increased latitudinal temperature
gradients, increased ventilation of the deep ocean, and affected a range of

Quality ATTRIBUTE ACCURACY REPORT: Beginning with the data for January 1982, Cooperative data were processed through a completely revised system. Relying heavily on new computer editing procedures, data have been subjected to internal consistency checks, compared against climatological limits, checked serially, and evaluated against surrounding station observations. The historical data were converted from ... existing digital files and structured into the element structure format. These data were processed through a gross value check and not the current edit system. It is NCDC's goal to bring these historical files up to the same level of quality as those from 1982 onward as resources become available. Thus, benign neglect, state of the art processing (circa 1952), and limited money/people resources have contributed toward less than optimum conditions in maintaining integrity of the digital files before 1982. Soil data were added in January 1982 with approximately 250 stations reporting soil data. Soil data before 1982 are available in DSI-9639. In January 1987, the 1982 and 1983 soil data were removed from the primary period of record data tapes. 1982-83 soil data processing problems resulted in poor data quality of the monthly soils. These data are available on a separate magnetic tape containing just 1982-83 soil data. There may be a few cases in which precipitation and temperature are in metric units but are not labeled as such in the "Element Units" field. This seems to be limited to data from the early 1960's from the U.S. Virgin Islands and Puerto Rico. Some data files contain what appears to be near duplicate records. For example, one record may contain data for January through April and show the remaining months as missing. The second record may show data for January through April as missing and the remaining months as present. The reason there are two records is that the station changed climate divisions during the year. The first record will show some division number, and the second record will show a different division number.
