Observation of manganese nodules and crusts in the Blake Plateau area

Visual observations of manganese deposits on the Blake plateau from a manned submersible indicate that the occurrence of manganese as nodules, slabs, or pavement may be related to localized environmental conditions. Manganese is concentrated at the crests of sand waves and, in areas of gentle slope, grades locally from nodules to solid pavement.

Trace-element contents in ash samples from DSDP Leg 19 sediments

The Sr, Rb, Ti, and Zr concentrations of 16 volcanic ash samples from Leg 19 of the Deep Sea Drilling Project were determined by X-ray fluorescence. The age of each ash sample had been established previously by faunal criteria and had been confirmed by fission-track dating. Variations in the trace-element concentrations through the past 8 m.y. are clearly seen. Seven of the ashes are older than 4 m.y., have low TiO2 contents, and have Sr concentrations of less than 200 ppm; they are thus similar to tholeiitic basalts of island arcs. Nine ashes are younger than 4 m.y. and are similar in trace-element content to andesite. Magmatic evolution of the Aleutian arc over the past 8 m.y. is clearly shown.

Annotated record of the Fe-Mn concretions recovered in the Kara sea during the M. Gorkiy survey in 1945

The Kara scientific expedition of 1945, using the fishing trawler M. Gorkiy and survey vessel Osetr, took sediment samples in the Kara Sea in addition to other oceanographic work. The investigations of sediments composition was compared with biological and hydrological data obtained in the same areas. The sediments sampled were subjected to mechanical, mineralogical, chemical and faunistic analyses. During this survey iron-manganese concretions were recovered.

Observation of manganese deposits in the Blake Plateau, Florida and Caribbean sea areas

Designed by the Westinghouse Corporation in collaboration with Jacques Cousteau, DEEPSTAR-4000 is a deep diving research vehicle based on Captain Cousteau's DIVING SAUCER. An evaluation of DEEPSTAR's operational performance at sea is presented in this report through a description of typical dive procedures and the actual NAVOCEANO dive results.

A viagem da U. S. Astronomical Expedition (1849-1852): observar estrelas e relatar a América do Sul

O trabalho analisa a expedição astronômica realizada pela Marinha norteamericana ao Chile, durante os anos de 1849 a 1852, comandada pelo oficial e também astrônomo James Melville Gilliss. O objetivo foi compreender os interesses científicos, políticos, geopolíticos e comerciais que motivaram a viagem, bem como as imagens e representações sobre a América do Sul, especialmente do Panamá, Peru, Chile e Argentina, construídas e divulgadas através do relatório oficial da expedição, com o título \"The U.S. Naval Astronomical Expedition to the Southern Hemisphere during the years (1849- 1852). Esta pesquisa também procura examinar os diferentes dispositivos discursivos utilizados pelos oficiais que escreveram o relatório, James Gilliss e Archibald MacRae, discutindo dissensões e diferentes visões sobre o modo de veicular dados científicos, e também modos distintos de relatar a América do Sul.
