“…This ratio was 3.9 ± 1.5 in marine particulate matter and lower (1.3 ± 0.6) in sediments, suggesting that resuspension of sediments was not the main source of suspended particles and biogenic formation is possible. According to Price et al ratio values ranged from 3 to 5 suggest a biogenic source of Ca probably due to calcareous organisms occurred in water column [22]. However, high ratios were also found in riverine particulate matter (2.0-4.5), in wastewaters (2.0-27) and in streams (2.4-17).…”

“…Biogenic activity can affect the presence of elements such as P, N, Ba, Ca, Si in suspended particulate matter [4,22]. The ratio of Ca/Al in marine particulate matter is often used as an indication of biogenous occurrence of Ca.…”

“…Similarly, the Si/Al ratio is also considered as an indication of possible changes in Si occurrence from biogenic activity, although there are difficulties due to the predominance of this element associated with quartz and aluminosilicates materials [22]. The Si/Al ratio was 3.2 ± 0.9 in marine particulate matter and 2.7 ± 0.3 in sediments.…”

“…This area is influenced by 2 of the most important rivers (Axios, Aliakmon) in the northern Aegean. It receives significant inputs of particulate matter and dissolved constituents (Price et al 2005), creating favorable conditions for phytoplankton growth and thus is an ideal area for the cultivation of mussels.…”

), suggesting that X k should be treated as a site-specific parameter. Food density (X) was adapted to include not only Phyto-C but also POC in the diet of M. galloprovincialis and only when Phyto-C density was low compared to POC density. Results showed a small contribution of POC during spring in the Maliakos Gulf and almost none at Thermaikos Gulf. The simulated mussel growth showed good agreement with field data. Sensitivity tests on the calibrated parameters (E, R and X k ) were performed to investigate model uncertainty. The standard deviation of simulations with perturbed parameter/initial values remained relatively small and appeared to increase as the modeled mussel grew, in agreement with observations.

This paper presents geochemical profiles of a tephra-bearing minerotrophic peat column from NE-Iceland obtained using various elemental analyses of the solid phase and the pore water. The influence of tephra grain size, thickness and composition of each tephra on the peat geochemistry was investigated. Interpretations are supported by a statistical approach, in particular by autocorrelation, and by microscopy observations. Minerotrophic peat geochemistry may be strongly dependent upon post-depositional mobilization and possible leaching of elements as demonstrated by Fe and trace metal concentration profiles. Chemical elements, and more specifically potentially harmful metals, can be slowly leached out of volcanic falls during their weathering and re-accumulate downwards. It is emphasised that a tephra deposit can act as an active geochemical barrier, blocking downward elemental movements and leading to the formation of enriched layers. In this study, the formation of poorly amorphous Fe phases above the Hekla 3 tephra is shown. These poorly crystalline Fe phases scavenged Ni.
