Bundled turbidite deposition in the central Pandora Trough (Gulf of Papua) since Last Glacial Maximum: Linking sediment nature and accumulation to sea level fluctuations at millennial timescale 5
Jorry, Stephan J.; Droxler, Andre W.; Mallarino, Gianni; Dickens, Gerald R.; Bentley, Sam J.; Beaufort, Luc; Peterson, Larry C.; Opdyke, Bradley N..
Since Last Glacial Maximum (23-19 ka), Earth climate warming and deglaciation occurred in two major steps (Bolling-Allerod and Preboreal), interrupted by a short cooling interval referred to as the Younger Dryas (12.5-11.5 ka B. P.). In this study, three cores (MV-33, MV-66, and MD-40) collected in the central part of Pandora Trough (Gulf of Papua) have been analyzed, and they reveal a detailed sedimentary pattern at millennial timescale. Siliciclastic turbidites disappeared during the Bolling-Allerod and Preboreal intervals to systematically reoccur during the Younger Dryas interval. Subsequent to the final disappearance of the siliciclastic turbidites a calciturbidite occurred during meltwater pulse 1B. The Holocene interval was characterized by a lack...

Condiciones oceanográficas frente a la costa ecuatoriana durante octubre-diciembre 1990 20
Sonnenholzner, S..
En este informe se presentan los resultados obtenidos en los tres cruceros oceanográficos, T90/09/1 - T90/11/2 - T90/12/4. Se detalla la evolución de las condiciones de Temperatura Superficial del Mar (TSM), Salinidad Superficial del Mar, estructura térmica y halina subsuperficial, masas de agua y oxígeno. La TSM frente a la costa ecuatoriana se encontró dentro de los rangos normales para la época, a excepción de noviembre en el cual se registró un enfriamiento de las condiciones superficiales al sur de la región con anomalías de 1º-2ºC. El Frente Ecuatorial definido por las isotermas de 20º-26ºC estuvo bien desarrollado, ubicándose entre 1ºN-3ºS frente a la costa ecuatoriana, siendo esta mas intensa durante noviembre, producto del enfriamiento...

Guide to operational procedures for the collection and exchange of oceanographic data (bathy and tesac) 20
All nations are profoundly influenced by the world oceans in many ways - some direct and obvious, others indirect and more subtle. Even those countries without ocean coastline feel the influence of the ocean, for example, as it affects world-wide weather and climate and In the availability of foreign goods and access to distant markets. Some influences of the ocean are benefitial; others may be detrimental to human activities ; most are beyond our ability to control, except in very limited ways, but, forewarned with a knowledge of the state of the ocean and even a limited prediction of future trends, it may often be possible to maximize the beneficial effects and to avoid or guard effectively against those which could be detrimental. The Integrated Global...

La subcorriente ecuatorial: características oceanográficas alrededor de las Islas Galápagos 20
Lucero, M..
El propósito de este trabajo consiste en presentar nuevas evidencias de la presencia de esta subcorriente, que pasa a través de las Islas Galápagos y que sus aguas han sido observadas hasta los 82°W (frente al Golfo de Guayaquil), este trabajo esta basado en mediciones directas de corrientes efectuadas a bordo del BAE ORION, en un crucero oceanográfico desarrollado entre abril y mayo del 2002.
