Description:
During "Meteor"cruise 1965 the author collected 134 samples of surface sediments from the Iranian part of the Persian Gulf. Benthic Foraminifera populations have been analysed for determining their depth zonation. These data are supposed to allow detailed depth interpretation of pleistocene sediments found in cores. In addition, the ecological information might be usefull to reconstruct the depositional environment of fossil sediments in similar shallow epicontinental seas. The investigation is published in two parts: the present part 1 contains the catalogue of species with short discussions of taxonomic problems, notes on the distribution within the Persian Gulf and 11 plates, partly with scanning electron micrographs. The results of the statistical analysis are given in data tables which include number of species, percentages of 2 (and 5) ranked species, standing crop and foraminiferal numbers. The author used "species groups" to avoid ambiguities with species requiring additional taxonomic studies. However, species numbers within these units are estimated to yield applicable diversity information. - A total of 52 species and 7 "species groups" were separated, 2 new species were described. Complete series of reference material were deposited in the British Museum (N.H.), London and the U.S. National Museum, Washington (BMNH 1973: 10: 22: 1 172 and USNM 36/203331 - 203383). Part 2 (ecological part) is in preparation and is supposed to contain diagrams showing depth distribution, relation of fauna with grain size of sediments, distribution maps and the ecological interpretation of dominant distribution patterns.
