Manganese nodules, coatings and crusts from the Pacific and the Indian oceans were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES).... -
Accumation rates of manganese in pelagic sediments using 130Th activity
For 7 pelagic sediment cores, the decrease in unsupported 130Th activity with depth in the core was used to establish the mean accumulation rate over the last 300 000 years.... -
X-ray fluorescence (XRF) of manganese deposits recovered by the R/V Robert Co...
From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other... -

The Manihiki Plateau, a 600,000 km2 smooth and nearly flat-topped feature, lies in the west equatorial Pacific. Danger, Nassau, Suvorov and Manihiki Islands rise from the... -
(Table 2) Age determination of Southern Ocean sediments
The silicic acid leakage hypothesis (SALH) predicts that during glacial periods excess silicic acid was transported from the Southern Ocean to lower latitudes, which favored... -
