Diurnal Variability of Persistent Organic Pollutants in the Atmosphere over the Remote Southern Atlantic Ocean 5
Gioia, Rosalinda; Macleod, Matthew; Castro-jimenez, Javier; Nizzetto, Luca; Dachs, Jordi; Lohmann, Rainer; Jones, Kevin C..
A diel (24-h) cycle with daytime atmospheric concentrations higher than nighttime concentrations by a factor of 1.5-3 was observed for several low molecular weight polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) in remote areas of the tropical South Atlantic during a cruise in October-November 2005. In contrast, high molecular weight PCBs and PAHs did not display diurnal variability. A model which has successfully explained diel variability of persistent organic pollutants (POPs) over land could not reproduce the observed diel cycle by considering variability in temperature, atmospheric OH radical concentrations, atmospheric boundary layer height and wind speed as causal factors. We used the model to conduct two bounding...

JERICO-NEXT. Approaches to monitor European coastal seas 5
Durand, Dominique; Puillat Felix, Ingrid; Karlson, Bengt; Grémare, Antoine; Nizzetto, Luca; Rubio, Anna; Laakso, L; Mourre, Baptiste.
The objectives of JERICO-NEXT are to address the challenge of observing the complexity and high variability of coastal areas at Pan-European level, in the framework established by European Directives (WFD, MSFD) and the operational marine services. The JERICO-NEXT project aims at extending the EU network of coastal observations developed in JERICO (FP7) by adding new innovative infrastructures while integrating biogeochemical and biological observations. The main target of JERICO-NEXT is to provide the researchers with continuous and more valuable coastal data coupling physical and biological information. The JERICO research infrastructure (JERICO-RI) is valorised through six Joint Research Activity Projects (JRAP) that address key environment challenges...

JERICO-NEXT. JRAP Synthesis and contribution to the strategy for the future 5
Gremare, Antoine; Puillat, Ingrid; Karlson, Bengt; Artigas, Felipe; Nizzetto, Luca; Rubio, Anna; Laakso, Lauri; Mourre, Baptiste.
Six Joined Research activity Projects (JRAPS have been achieved within JERICO-NEXT. These projects have been set up to tackle some of the complex technical and scientifical issues associated with the implementation of Coastal Ocean Observing over a wide range of environmental conditions and spatiotemporal scales. The topics of these projects have been defined in relation with some of the Marine Strategy Framework Directive: JRAP 1: Biodiversity of plankton, harmful algal blooms and eutrophication, JRAP 2: Monitoring changes in microbenthic biodiversity, assessing potential environmental controls and functional consequences JRAP 3: Occurrence of contaminants in Northern coastal waters and biological responses JRAP 4: 4D characterization of trans-boundary...

JERICO-NEXT. Progress Report #2 5
Puillat Felix, Ingrid; Karlson, Bengt; Artigas, Luis Felipe; Grémare, Antoine; Nizzetto, Luca; Rubio, Anna; Laakso, Lauri; Seppala, Jukka; Mourre, Baptiste.
The WP4 of the JERICO-Next is a synthesis of the project built upon activities in other WPs, gathering the consortium around applied Joint Research Activity Projects (JRAPs) selected to put forward the added value of JERICO-NEXT. In order to reach this objective, WP4 keeps on track the JERICO-NEXT course of actions via synthesis and application activities based on interactions with other WPs. WP4 helps establishing some topical approaches for the scientific strategy in WP1 (task 1.2) and will give inputs to establish the network strategy after JERICO-NEXT (task 1.6). Indeed, six JRAPs are being implemented to address different key environmental questions and/or policy requirements such as those considered by the MSFD, and according to the 6 JERICO...
