Response of Benthic Foraminifera to organic matter quantity and quality and bio...
Martins, Maria Helena; Silva, Frederico; Laut, Lazaro L. M.; Frontalini, Fabrizio; Clemente, Iara M. M. M.; Miranda, Paulo; Figueira, RubensThis work analyses the distribution of living benthic foraminiferal assemblages of surface sediments in different intertidal areas of Ria de Aveiro (Portugal), a polihaline and anthropized coastal lagoon. The relationships among foraminiferal assemblages in association with environmental parameters (temperature, salinity, Eh and pH), grain size, the quantity and quality of organic matter (enrichment in carbohyd...
The ITRAX core scanner, a useful tool to distinguish anthropic vs. climatic inf...
Martins, Virgínia A.; Dias, João A.; Bernardes, Cristina; Rubio, Belén; Bernabeu, Ana; Rey, Daniel; Soares, António M.; Sobrinho, FredericoThe main goal of this work is to distinguish anthropic and climatic influences in sediments from the lagoon of Aveiro (Portugal). This study is based on a core (240-cm long) collected in Murtosa Channel. Optical and X-radiographic images and high-resolution elemental profiles were acquired with ITRAX micro-X-ray fluorescence (XRF) core scanner. Samples collected at each ≈3 cm along the core were analysed for gr...
