The Mediterranean is considered a hot-spot for plastic pollution, due to its semi-enclosed nature and heavily populated coastal areas. In the present study, a basin-scale coupled hydrodynamic/particle drift model was used to track the pathways and fate of plastics from major land-based sources (coastal cities and rivers), taking into account of the...

The effect of Black Sea Water (BSW) inputs on the productivity and food web dynamics of the N. Aegean Sea was investigated, by means of sensitivity simulations, investigating the effect of the inflowing BSW, in terms of inorganic nutrients and dissolved organic matter. Considering the importance of the microbial loop in ecosystem functioning and th...

In this work the ability of nesting two hydrodynamical models, the high-resolution Cretan Sea shelf model and the lower resolution regional ALERMO model, was investigated. A new database was developed by objectively analysing raw climatological data from the MODB database enriched with in situ measurements collected by the Institute of Marine Biolo...

The semi-enclosed environment of Pagasitikos Gulf was the object of a holistic study during 1998–1999 following the appearance of mucilaginous events during summer. A major part of the INSEA project was the development and implementation of a coupled modeling system capable of reproducing all the major characteristics both in physical and biologica...

Pagasitikos Gulf (Greece), presents an interesting area as it depicts strongly non-linear ecosystem character-istics. It is a shallow coastal area where the marine ecosystem picture is strongly influenced by non-linear hydrodynamic interactions and instabilities. In this study, we explore and assess the major influential vari-ables of the surface p...

Within the framework of the European INSEA project, an advanced assimilation system has been implemen-ted for the Pagasitikos Gulf ecosystem. The system is based on a multivariate sequential data assimilation scheme that combines satellite ocean sea color (chlorophyll-a) data with the predictions of a three-dimensional coupled physical–biochemical...

In order to support management decisions for aquaculture, a modeling tool capable of simulating the ecosys-tem response was developed and is presented here. The impact on the Pagasitikos gulf ecosystem from two marine fish farms, one in a well protected cove and one in a more exposed area of the gulf, is explored and analyzed in the framework of th...

Scenario testing of fisheries management strategies using a high resolution ERSEM–POM ecosystem model. – ICES Journal of Marine Science, 64: 1627–1640. Ecosystem models are just beginning to be considered as management tools. In te...

During the second phase (2003–2006) of the Mediterranean ocean Forecasting System Project (MFS) named Toward Environmental Predictions (MFSTEP) one of the three major aims was the development of numerical forecasting systems. In this context a generic Biochemical Flux Model (BFM) was developed and coupled with hydrodynamic models already operating...

The Pagasitikos gulf ecosystem is studied through the analysis of experimental field data acquired during several monitoring projects and the application of a complex biogeochemical model. The gulf was separated into three different parts (internal, top central-external, bottom central-external) according to the patterns exhibited by the key ecosys...

In this work the development and the application of an operational management tool for the Greek Seas is described. This tool consists of a three-dimensional floating pollutant prediction model coupled with a weather, a hydrodynamic and a wave model in order to track the movements and the spreading of the pollutants and indicate those coastal areas...

This paper presents the methodology and results of applying computer-based numerical models to assess the environmental impact due to sewage discharge at the coastal area of Ierapetra Bay in south Crete. For this purpose, objectively analyzed in situ data of physical and biochemical parameters, as well as a three-dimensional hydrodynamic model and...
