Peruvian margin at 11° S, core 459-MUC53 (1005 m)
Peruvian shelf and slope, Peru

- Type
- Sediment
Multicorer from cruise M77/1 on the 11° S transect, Peruvian oxygen minimum zone. Pore waters are as heavy as or heavier than biogenic opal: precipitation of authigenic alumino-silicates about 2 ‰ lighter. Station coordinates not given in the article. Opal too scarce (1-2 wt%) to measure. Called 549-MUC53 in the text, 459-MUC53 in Table 1. Site not precisely located: the source gives no coordinates.
