Distribution of opal and quartz on the ocean floor of the subtropical southeastern Pacific

Geology, 1977
The distribution patterns of opal and quartz on the ocean floor of the subtropical southeastern Pacific have been defined by analyzing 59 surface-sediment samples. The opal distribution resembles that of primary productivity in the surface waters, except along the Peruvian and northern Chilean coasts, where dilution reduces opal values.

Silica distribution in interstitial waters and sediments from the southeastern pacific

Sedimentary Geology, 1982
Abstract Analyses for silica in the interstitial water of five cores from the southeast Pacific are presented. Silica is enriched in these interstitial waters resulting in a vertical flux of silica of between 10 and 50 μmol cm −2 yr −1 from the sediment into the overlaying seawater.

Major Neogene events of the Southeastern Pacific: the Chilean and Peruvian record

Palaeogeography, Palaeoclimatology, Palaeoecology, 1990
Abstract According to the biochronostratigraphic model proposed, the Neogene marine deposits in Chile and Peru represent two independent transgressive sequences (Alloformations), separated by a major regional hiatus. The earlier sequence, NSEPS-I, would stretch from the top of the Early Miocene up to the base of the Late Miocene (ca. 19-10 m.y.

Assessing the Efficiency of the Marine Protected Area Systems in the Southeastern Pacific

Aquatic Conservation: Marine and Freshwater Ecosystems
ABSTRACTAmidst accelerated degradation of marine ecosystems due to anthropogenic disturbances, marine protected areas (MPAs) have been implemented globally to protect marine biodiversity, mitigate ecosystem degradation and replenish fisheries. In many countries, the creation of MPAs increased after the 2011 Aichi Targets, but in most cases, MPAs face ...

Southeastern pacific blocking episodes and their effects on the South American weather

Meteorology and Atmospheric Physics, 1999
Southeastern Pacific blocking episodes are studied using 17 years of reanalyzed daily data from the National Centers for Environmental Prediction (NCEP). The anomalous sea level pressure (SLP) within the area bounded by the longitudes of 130° W and 100° W and the latitudes of 50° S and 70° S is used as the base variable to determine periods with 7 or ...

[Vertical distribution of the saprophytic microflora in the southeastern portion of the Pacific Ocean].

Mikrobiologiia, 1980
Data pertinent to the distribution of saprophytic bacteria at various depths in the south-eastern region of the Pacific Ocean were analyzed by the method of multiple comparison. A map was constructed for the vertical distribution of the density of saprophytic microflora whose concentration in this region was lower than in other regions of the ...
