The OceanGliders program started in 2016 to support active coordination and enhancement of global glider activity. contributes the international efforts Global Ocean Observation System (GOOS) for Climate, Health, Operational Services. It brings together marine scientists engineers operating gliders around world: (1) observe long-term physical, biogeochemical, biological ocean processes phenomena that are relevant societal applications; and, (2) contribute GOOS through real-time delayed mode...
The Mediterranean community represented in this paper is the result of more than 30 years EU & nationally funded coordination that has led to key contributions science concepts and operational initiatives. Together with establishment services, been coordinating Universities, research centers, infrastructures private companies implement advanced multi-platform integrated observing forecasting systems facilitate advancement scientific achievements mission-oriented innovation. As a result, able...
Decades of climate research underscore the ocean’s essential role in regulating Earth’s heat and carbon cycles. The strong ocean-atmosphere interactions, intensified by change, alter our planet's physical biogeochemical dynamics, leading to ocean acidification, warming, ice melt, sea level rise, posing serious risks biodiversity, ecosystems, human livelihoods. Thus, a comprehensive sustainable global monitoring system has become priority. Within EU, marine Research Infrastructures (RIs) play...
In this work we present the implementation of a wave forecast/hindcast system for Mediterranean Sea at 1/10º horizontal resolution and show first assessment its performance by inter-comparing model results to observational data time series selected points period 2000-2001. The which is part POSEIDON-II operational includes WAM – Cycle4 WAVEWATCH-III forecast models (implemented within same region) one way coupled with non-hydrostatic version ETA atmospheric provides 3-hour intervals...
Temperature and salinity time series provided by three POSEIDON monitoring stations (buoys) are examined in order to study the seasonal interannual variability of water mass characteristics. The sites at Athos (North Aegean Sea), E1M3A (Central Cretan Sea) Pylos (Eastern Ionian were chosen, as these buoys provide measurements various depths, while they represent 3 major basins respectively. T S characteristics reveals important changes highlights particular each basin. Dense production...
Abstract. In order to assess seasonal and interannual variability in the export of particulate matter its main constituents, sediment traps were deployed at five successive depths from February 2006 March 2010 deepest basin Mediterranean (SE Ionian Sea, NESTOR site). The average total mass fluxes 66, 58, 54, 34, 52 mg m−2 d−1, 700, 1200, 2000, 3200, 4300 m, respectively. temporal variations flux showed similar signal all sampling with higher values spring–summer lower autumn–winter. Changes...
Abstract. There is a general scarcity of oceanic observations that concurrently examine air–sea interactions, coastal–open-ocean processes and physical–biogeochemical processes, in appropriate spatiotemporal scales under continuous, long-term data acquisition schemes. In the Mediterranean Sea, resulting knowledge gaps observing challenges increase due to its oligotrophic character, especially eastern part basin. The open Cretan Sea's biogeochemistry considered be representative greater area...
The development and first assessment of a high resolution eddy-resolving forecasting system for the Aegean Sea hydrodynamics, developed as part POSEIDON-II European Economic Area (EEA) Grants project Coastal Operational Observing Forecasting (ECOOP) Union (EU) project, is presented.The uses an assimilation scheme based on localized version Singular Evolutive Extended Kalman (SEEK) filter with partial evolution its correction directions.The used to correct forecast state 1/30o Princeton Ocean...
The effective management and protection of the marine ecosystem as requested by European latest directives can be achieved only an operational monitoring forecasting environmental conditions that require use multi-variable real-time measurements combined with advanced physical ecological numerical models. A modern approach to ocean observations involves a variety sources, including satellite-based instruments, in-situ platforms such surface sub-surface buoys floats, autonomous vehicles...
In the framework of POSEIDON Project, a network open sea oceanographic buoys equipped with meteorological and sensors has been operational in Aegean Sea since 1998. The analysis upper-ocean physical data (currents at 3m, temperature salinity 3-40m depths) collected during last 2 years from stations North basin indicates strong temporal variability flow field hydrological characteristics both synoptic seasonal time scales. northern part is mainly influenced by Black Water outflow mesoscale...
The integration of the radioactivity spectrometer KATERINA II in a fixed station (buoy) POSEIDON network at North Aegean Sea within framework MARRE Project is presented. acquisition period lasted from 20 November 2019 till 22 February 2020. An intense increment activity concentration radon progenies (up to an order magnitude) was recorded during rainfall. More specifically, 214Bi varied 0.09 0.53 Bq L−1 without rainfall and 214Pb 0.14 0.81 L−1. ranged 0.4 5.4 0.3 5.3 minimum detectable...
A preliminary analysis of atmospheric and surface oceanic observations from the POSEIDON buoy network is presented. The data set consists concurrent physical properties at atmosphere-ocean boundary layers as well chlorophyll- f (chl- ) dissolved oxygen content subsurface layer. quality evaluated using standard procedures comparison to reference measurements with special focus on bio-fouling effects. extended temporal spatial coverage provides, for first time in Aegean Sea, opportunity study...
Research infrastructures have been established throughout Europe in order to create robust organizations that will facilitate and enhance research innovation processes advance society with innovative products services. The Hellenic Integrated Marine Observing, Forecasting Technology System (component of HIMIOFoTS RI) has implemented the framework National Roadmap for Infrastructures form a large-scale infrastructure marine environment Greece. It links together ocean observing forecasting...
Abstract. As part of the integrated ECOOP (European Coastal Sea Operational observing and Forecasting System) project, HCMR upgraded already existing standalone Oil Spill System for Aegean Sea, initially developed Greek Oceanography (POSEIDON), into an active element European Decision Support (EuroDeSS). The system is accessible through a user friendly web interface where case scenarios can be fed oil spill drift model component, while synthetic output contains detailed information about...
