MERCATOR OCEAN JOURNA: 
SEPTEMBER 2021 
To be noted, the introduction of a new centralized DU has 
been one of the major technical challenges for both the 
new DU's team and producers, as it implied changes in 
zonsolidated procedures and the introduction of new 
components such as (but not limited to) the Delivery Buffer 
Service (DBS). 
1. COPERNICUS MARINE SERVICE 
PHASE 2 DU - OVERVIEIN 
In order to meet the high level of service required by new 
requirements, in 2018 a new Consortium has been formed, 
led by the Consiglio Nazionale delle Ricerche (CNR - prime 
Contact Point) and composed by: 
- CNR (with the support of Collecte Localisation Satellites 
SA (CLS), Serco Italia SpA, and Laser Romae sır.l), 
ETT S.p.A, 
ACRI ST (with the support of adwaisEO), 
Institut Francais de Recherche pour l’Exploitation de 
la Mer (IFREMER: with the support of Altran). 
This Consortium has a strong and long experience in 
leading International Project and Services, IT&ICT solutions 
in operative environment, software development for both 
producing, archiving and disseminating Earth-Observation 
data, including Copernicus Services. 
The Copernicus Marine Service DU provides an IT/ 
dissemination expert centre service to the organisation and 
provides operational links between the other Service's 
alements and users. In fact, the DU collects products fror 
production units and disseminates them to users, monitoring 
»perations for both near real time and forecast (NRT) anc 
multi-year (MY) products. This organization pursues the fina 
goal of filling the gap between science and technology. The 
DU provides the Copernicus service with continuity, and 
consolidates contact points, resources and access points. It 
provides flexible, robust and scalable DU systems, improving 
the operational level of the system and setting up Key 
Performance Indicators’ (KPIs) dashboards. It resulted in a 
new DU Architecture, as shown in Figure 2. This article 
-eports the results achieved during the period 2018-2027,
