During Leg 181, seven locations (Sites 1119-1125) were drilled off the eastern coast of New Zealand. Although the sites were primarily targeted to reconstruct the stratigraphy and paleoceanography of the region (Shipboard Scientific Party, 1999, doi:10.2973/odp.proc.ir.181.101.2000), they are particularly interesting from a geochemical perspective because, as clearly evidenced by shipboard pore water and gas analyses, recovered sediment cores span an exceptional range of chemical environments. Pore water alkalinity, NH4+, SO4**2-, and PO4**3- concentrations, as well as headspace CH4 concentrations, indicate significant differences in sediment redox conditions across the region (Shipboard Scientific Party, 1999, doi:10.2973/odp.proc.ir.181.101.2000). The distribution of solid and dissolved manganese plays an important role in geochemical interpretations of such sedimentary environments (e.g., Froelich et al., 1979, doi:10.1016/0016-7037(79)90095-4; Thamdrup and Dalsgaard, 2000, doi:10.1016/S0016-7037(00)00496-8). Dissolved Mn2+ concentrations of pore waters at four sites (1119, 1122, 1123, and 1125) drilled during Leg 181 are presented in this report. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.786364"! ** DEPTH, sediment is given in mbsf.
