Almost all ICES member countries have policies that address the impacts of human activities on marine ecosystems. These policies may explicitly be framed as an implementation of an ecosystem approach. An important example is the Marine Strategy Framework Directive (MSFD) of the European Union (EC, 2008), which is a comprehensive framework for achieving good environmental status (GES) for Europe...
Chronic undersampling of the marine environment, including both biological and physical components, has been and remains a major block to understanding how marine ecosystems function and how they respond to changes, whether natural or anthropogenic. Consequently, data-based models that accurately predict local variations in the abundance of plant and animal life in the sea are rare or do not ex...
This paper considers a mixture of sedimenting particles at low Reynolds numbers and volume fractions. Simple theoretical arguments have long suggested that for a random suspension of particles in an infinite system, the fluctuations in the velocity about the mean should diverge with system size. On the other hand, experiments have shown no such divergence. The primary goal of this paper is to e...
In their article entitled: “The decrease in erythrocyte sedimentation rate related to general anesthesia”, Clin Hemorheol Microcirc 35 (2006) 459–462, Caglayan and co-workers have investigated the effects of general anesthetic agents on erythrocyte properties, reflected in changes in the Erythrocyte Sedimentation Rate (ESR). In their introduction the authors referred to the one-hour ESR method ...
Estimation of annual erosion and sedimentation in Babolroud catchment using EPM and Fournier methods
One of the problems of controlling erosion and sedimentation in catchment areas is the lack of statistical data to accurately estimate the amount of sedimentation and erosion. In order to implement soil protection programs and determine methods to reduce sedimentation, it is necessary to estimate the total volume of annual sediment production. The purpose of this study is to estimate the erosio...
The Central Iran Basin is a region with unique environmental characteristics in which the Late Paleogene–Early Neogene benthic foraminifera display distinctive distributions and abundances that can assist identifying intervals best reservoir potential. Lipidocyclinid miogypsinid zonal marker taxa this be correlated those SBZ23 (European Basin), indicating an Oligocene (Chattian) age. With sedim...
Global climate change and ocean acidification pose a serious threat to marine life. Marine invertebrates are particularly susceptible to ocean acidification, especially highly calcareous taxa such as molluscs, echinoderms and corals. The largest of all bivalve molluscs, giant clams, are already threatened by a variety of local pressures, including overharvesting, and are in decline worldwide. S...
