Sea lions, sacrifice, and ritual : The symbolism of Moche Island imagery

The Mochica, or Moche (c. 100-800 AD) culture, flourished along the northern Peruvian coast. The Moche did not have a formal written language; as such, contemporary scholars base their analysis on Moche iconography and archaeological burial remains. Especially renown for their ceramic artistry, Moche vessels exhibit a wide range of subject matter, including animal and enigmatic figural representations that evoke terrestrial, marine and possibly, spiritual realms. While research has focused on political organization and the interrelationship between sacrifice and warfare, many marine themes have not been fully explored in the discourse. An exploration of sea lion imagery and sacrifice themes suggests that the marine mammals were ritually hunted. A careful iconographic analysis of island scenes demonstrates ritual and gender affiliations held by the Moche about sea lions. In a multi-disciplinary approach, scientific, archaeological and ethnographic resources substantiate this claim.

Factors Affecting Jaguar and Puma Predation on Livestock in Costa Rica

The wild cats and the livestock farmers are part of the space conflict in the rural areas in Latin America. In this sense, this conflict causes a discomfort among the livestock producers due to the loss of animals and, consequently, it also causes a negative reaction towards the wild cats leading such reaction into the elimination of the wild cats per se. Although, there have been some initiatives have tried to approach such conflict by recommending mitigation and prevention measurements to the producers, these measurements are undertaken without coordination. For this reason, the following project presents a planning tool that can ease the coordination processes undertaken for the solving of the conflict between human beings and wild cats.

Element concentrations of aluminosilicate components from ODP sites in the Pacific Ocean

We measured major and trace element concentrations in the operationally defined, chemically extracted, residual aluminosilicate component of sediment from Ocean Drilling Program Sites 1215 and 1256 in the central and eastern equatorial Pacific Ocean and found that this residual component contains volcanogenic and authigenic aluminosilicates in addition to inferred eolian material. While the residual component younger than 20 Ma from the central Pacific (ODP Site 1215) is similar compositionally to upper continental crust and suggests an increase in the delivery of Asian dust material since 20 Ma, the residual in sediment older than 20 Ma indicates significant amounts of volcanogenic and authigenic materials. Volcanogenic debris comprises as much as ~ 40% of the residual between 23-40 Ma, which coincides with the mid-Tertiary "ignimbrite flare-up" that occurred in much of western North America. The residual component extracted from the 50 Ma biogenic sediment reflects authigenic signatures (seawater-like negative cerium anomalies and elevated Fe/Si ratios). The previously interpreted increase in an andesitic detrital source in North Pacific locations may instead be authigenic material, presenting significant challenges for many paleoclimate proxies. Additionally, in the eastern Pacific (ODP Site 1256), the residual component contains ~70% of volcanogenic material, most likely originating from Central America, and also includes refractory barite. The ability to separately identify eolian, volcanogenic, and authigenic materials in the aluminosilicate component of pelagic sediment allows resolution, respectively, of the climatic, geologic, and chemical processes contributing to the paleoceanographic archive in this critical oceanic region.

Phosphorus dynamics in waters of the Pacific Ocean

Tagged phosphorus was used to measure principal indices of mineral phosphorus variations in the euphotic zone of the East Pacific, i.e. total rate of uptake of phosphate phosphorus by microplankton (A_t), fraction consumed by phytoplankton (A_p/A_t), and turnover time (T). A_t reached its greatest values (150-280 ng/l/hour) in the upwelling zone of the Peru traverse, where development of phytoplankton was induced by upwelling. In other areas of this traverse values were 40-80 ng/l/hour in surface layers. In less productive waters on two other profiles (off Central America and California), values were lower, between 20 and 40 ng/l. On the vertical profile maxima of A_t were found at the upper boundary of the thermocline. Turnover time of PO4 phosphorus (T) in zones of phytoplankton abundance was very short, between 1.5 and 4 days. At most other stations it was 10-40 days, increasing to 100-200 days or longer at the lower boundary of the euphotic zone. In areas of phytoplankton abundance it accounted for 60-80% of total uptake of PO4 phosphorus. But in zones of elevated bacterial abundance, A_p/A_t fell to 20-40%. Data indicating lack of correlation between PO4 phosphorus and productivity are presented. It is emphasized that the above measures of PO4 phosphorus dynamics can be used for obtaining measures of functional condition and successional phase of marine plankton communities.

Annotated record of the detailed examination of Mn deposits from the TRANSINDIK R/V Valdivia (VA 07) cruise stations

The studied material was taken from Central Indian Ocean central, during the "TRANSINDIK" campaign of the R/V Valdivia. The campaign was conducted from 14 December 1973 until 23 January 1974, between Beira (Mozambique) and Singapore via Port Louis (Mauritius). The samples were taken on 14 stations aligned on a profile trending West, following approximately the 15th parallel (south). This profile cuts through the Mascarene plateau Basin. The preliminary study presented in this report was carried out as part of a study into the genesis and diagenesis the ocean deposits of the central and southern areas of the Indian Ocean (Laboratoire de GÈologie du MusÈum d'Histoire Naturelle - R.C.P. 212) and under the CNEXO No. 74/1017 contract. The data collected supplements the results of the OSIRIS campaign (R/V Marion Dufresne - TAAF) concerning relations existing between morphostructure and sedimentation and, more particularly, the nature and age of metalliferous deposits associated with Mn concretions.

(Table 1) Geochemistry of glass shards at DSDP Leg 84 Holes

Three Leg 84 sites provided a good record of explosive volcanism onshore (in Central America). Ash layers and many ashy pods are interbedded in Recent to Oligocene strata. Evidence of the main periods of activity was noted in Recent to upper Pleistocene, Pliocene-Pleistocene, lower Pliocene to upper Miocene, lower Miocene, and upper Oligocene. Noticeable traces of older volcanism were found in upper Eocene strata. The chemical analyses of glass shards show a dacitic to rhyolitic composition with a low to moderate calc-alkalinity. A preliminary distinction of samples in three geochemical groups according to their K2O/SiO2 contents is done to test a magmatic evolution. Comparisons are made with Leg 67 and on-land data.

(Table 1) Sea surface temperature reconstruction for eastern equatorial Pacific surface sediment samples

Significant uncertainties persist in the reconstruction of past sea surface temperatures in the eastern equatorial Pacific, especially regarding the amplitude of the glacial cooling and the details of the post-glacial warming. Here we present the first regional calibration of alkenone unsaturation in surface sediments versus mean annual sea surface temperatures (maSST). Based on 81 new and 48 previously published data points, it is shown that open ocean samples conform to established global regressions of Uk'37 versus maSST and that there is no systematic bias from seasonality in the production or export of alkenones, or from surface ocean nutrient concentrations or salinity. The flattening of the regression at the highest maSSTs is found to be statistically insignificant. For the near-coastal Peru upwelling zone between 11-15°S and 76-79°W, however, we corroborate earlier observations that Uk'37 SST estimates significantly over-estimate maSSTs at many sites. We posit that this is caused either by uncertainties in the determination of maSSTs in this highly dynamic environment, or by biasing of the alkenone paleothermometer toward El Niño events as postulated by Rein et al. (2005).
