In the tropical Atlantic, planktonic fomminfera species are vertically distributed with highest abundances occunfng in the photic zone (approximately 0-100 m). The tropical Atlantic thermocline dips from east to west and varies seasonally due to changes in the southeast and northeast trade winds. In the east, the thermocline is in the photic zone, and in the west, the well-mixed surface layer e...

Is the pattern of childhood mortality due to diarrhea related to hydrography? To answer this kind of question we describe a method to examine associations between peak time of mortality from diarrhea in children less than 5 years for the period 1979-89 and relative location along the hydrologic regime of 8 major hydrographic regions in Brazil. In order to better understand the underlying hetero...

This study investigates the hydrographic processes involved in setting the maximumwintertime sea ice (SI) extent in the Labrador Sea and Baffin Bay. The analysis is based on an ocean and sea ice state estimate covering the summer-to-summer 1996/97 annual cycle. The estimate is a synthesis of in situ and satellite hydrographic and ice data with a regional coupled 1/38 ocean–sea ice model. SI adv...

The combination of structural and lithological data with morphometric indicators in a GIS environment constitutes methodological approach high added value to identify neotectonic deformations, particular the Quaternary outcrops where faults are generally masked by thick recent sediments. This approach, based on crossing multisource data, is used this work understand mechanisms that generate lan...

Bottom-water hypoxia (≤2 mg l–1 dissolved oxygen [DO]) greatly modifies the benthic habitat of estuaries, depending upon spatial extent, duration, and frequency. Bottom-water hypoxia often develops under conditions of density stratification, which inhibits vertical mixing, and warm temperatures, which enhance biological oxygen demand. Long-term, mid-channel data from the Neuse River Estuary in ...

Soil texture is key information in agriculture for improving soil knowledge and crop performance, so the accurate mapping of this crucial feature imperative rationally planning cultivations targeting interventions. We studied relationship between radioelements Mezzano Lowland (Italy), a 189 km2 agricultural plain investigated through dedicated airborne gamma-ray spectroscopy survey. The K Th ab...
