Abstract
Climatically induced changes in late Quaternary bathyal ostracod assemblages of the Camamu Basin, Brazil
Highlights
Research over the past 50 years has supplied invaluable data for the understanding of ostracod assemblages from deep oceanic regions (Benson 1975, Cronin 1983, Benson et al 1984, Whatley and Coles (1991), Majoran and Dingle 2002, Cronin and Dwyer 2003, Yasuhara and Cronin 2008, Yasuhara et al 2014, inter alia)
We studied a site in the Camamu Basin and discussed the geographic and stratigraphic occurrences of some species registered therein
Taxonomic analysis of the assemblages recovered from the core CMU 14 allowed the identification of 40 taxa, four of which proposed as new species (Figs. 2 and 3)
Summary
Research over the past 50 years has supplied invaluable data for the understanding of ostracod assemblages from deep oceanic regions (Benson 1975, Cronin 1983, Benson et al 1984, Whatley and Coles (1991), Majoran and Dingle 2002, Cronin and Dwyer 2003, Yasuhara and Cronin 2008, Yasuhara et al 2014, inter alia). Those studies revealed the bathymetric distributional pattern, and changes in assemblage composition along glacial, deglacial and interglacial stages, especially in response to variations of the oxygen minimum zone (OMZ) depth, and oceanic productivity. We studied a site in the Camamu Basin (off Bahia State) and discussed the geographic and stratigraphic occurrences of some species registered therein
