Electromagnetic dipole moments of baryons with strangeness and charm at the LHC
The program for measuring electric and magnetic dipole moments can be extended to baryons with strangeness and charm at the LHC. The obser- vation of an electric dipole moment would provide a signal for physics beyond the Standard Model and the existence of a new mechanism for CP violation that could help explain the observed difference between matter and antimatter in the Universe. Measuring magnetic dipole moments is useful for validating non-perturbative quan- tum chromodynamics theoretical models and providing new information about the internal structure of hadrons. Additionally, measuring the magnetic dipole moment for a particle and its antiparticle would allow a test of the CPT symmetry. We present new possibilities for conducting such measurements at the LHC by exploit- ing the spin precession of baryons with charm in bent crystals and baryons with strangeness inside the magnet of the LHCb tracking system. Feasibility studies of the proposed techniques and the expected precision of the measurements will be outlined
Assessing the impact of observations on ocean forecasts and reanalyses: Part 2, Regional applications
The value of global (e.g., altimetry, satellite sea-surface temperature, Argo) and regional (e.g., radars, gliders, instrumented mammals, airborne profiles, biogeochemical) observation-types for monitoring the mesoscale ocean circulation and biogeochemistry is demonstrated using a suite of global and regional prediction systems and remotely-sensed data. A range of techniques is used to demonstrate the value of different observation-types to regional systems and the benefit of high- resolution and adaptive sampling for monitoring the mesoscale circulation. The techniques include Observing System Experiments, Observing System Simulation Experiments, adjoint sensitivities, representer matrix spectrum, observation footprints, information content and spectral analysis. It is shown that local errors in global and basin-scale systems can be significantly reduced when assimilating observations from regional observing systems
GODAE systems in operation
During the last 15 years, operational oceanography systems have been
developed in several countries around the world. These developments have been
fostered primarily by the Global Ocean Data Assimilation Experiment (GODAE),
which coordinated these activities, encouraged partnerships, and facilitated
constructive competition. This multinational coordination has been very beneficial
for the development of operational oceanography. Today, several systems provide
routine, real-time ocean analysis, forecast, and reanalysis products. These systems
are based on (1) state-of-the-art Ocean General Circulation Model (OGCM)
configurations, either global or regional (basin-scale), with resolutions that range
from coarse to eddy-resolving, and (2) data assimilation techniques ranging from
analysis correction to advanced three- or four-dimensional variational schemes. These
systems assimilate altimeter sea level anomalies, sea surface temperature data, and
in situ profiles of temperature and salinity, including Argo data. Some systems have
implemented downscaling capacities, which consist of embedding higher-resolution
local systems in global and basin-scale models (through open boundary exchange of
data), especially in coastal regions, where small scale-phenomena are important, and
also increasing the spatial resolution for these regional/coastal systems to be able to
resolve smaller scales (so-called downscaling). Others have implemented coupling
with the atmosphere and/or sea ice. This paper provides a short review of these
operational GODAE systems.Published76-914.6. Oceanografia operativa per la valutazione dei rischi in aree marineN/A or not JCRope
GODAE systems in operation
During the last 15 years, operational oceanography systems have emerged in several countries
around the world. This emergence has been largely fostered by the GODAE experiment, during
which each nation engaged in this activity have organised partnership and constructive
competition. This trans-national coordination was very beneficial for the development of
operational oceanography, leading to economies of scales and more targeted actions. Today,
several systems provide routine real-time ocean analysis and forecast and/or reanalysis products.
They are all based on (i) state-of-the-art primitive equation baroclinic Ocean General Circulation
Model (OGCM) configurations, either global or regional (basin-scale), with resolutions that
range from coarse to eddy resolving and (ii) data assimilation techniques whose complexity
ranges from simple analysis correction to advanced 4D variational schemes. They assimilate
altimeter sea level anomalies, remotely sensed SST such as GHRSST products and in situ
profiles of T and S, including ARGO. Some systems have implemented downscaling capacities
in specific regions of interest including shelf/coastal seas. Some also have implemented coupling
with the atmosphere and/or the prognostic sea ice in polar regions. They are the GODAE system
in operation. They are reviewed in this paper. The GODAE system discussed here include: (1)

Oil spillrisk in the Adriatic Sea: an example of operational support capability in aid to the management of the emergency.
The Turkish cargo ship “Und Adriyatik” took fire in the early morning of the 6th of February 2008 (see figure
1) due to unknown reasons, only some 13 miles offshore the coasts of Rovinj, in Northern Croatia. The ship
was sailing from Istanbul to Trieste. Such an accident was a real threat to the Adriatic Sea, as the ship tanks
were full of engine fuel and many trucks were on board: the risk of explosion was high at any time.
At mid-morning of the same day, on behalf of the Slovenian Authorities the University of Port Rose
(Slovenia) contacted the “Gruppo Nazionale di Oceanografia Operativa” of the “Istituto Nazionale di
Geofisica e Vulcanologia” (GNOO-INGV) to get information on the hypothetical dispersion and fate of the
oil in case of spillage from the ship.
From several years, GNOO-INGV is running a daily marine forecast system of the Mediterranean Sea (MFS)
and of a nested higher resolution Adriatic Sea Forecasting Systeml (AFS) with an off-line coupled oil spill
model (Medslik). INGV receives atmospheric forecast from the Ufficio Generale Spazio Aereo e
Meteorologia (USAM) of the Italian Air Force and it is establishing an agreement with REMPEC (Regional
Marine Pollution Emergency Response Centre for Mediterranean Sea) to help for management of oil spill
emergencies
Status and future of global and regional ocean prediction systems
Operational evolution of global and regional ocean forecasting systems has been extremely significant in recent years. GODAE (Global Ocean Data Assimilation Experiment) Oceanview supports the national research groups providing them with coordination and sharing expertise among the partners. Several systems have been set up and developed pre-operationally and the majority of these are now fully operational; at the present time, they provide medium- and long-term forecasts of the most relevant ocean physical variables. These systems are based on ocean general circulation models (OGCMs) and data assimilation techniques that are able to correct the model with the information inferred from different types of observations. A few systems also incorporate a biogeochemical component coupled with the physical system while others are based on coupled ocean-wave-ice-atmosphere models.
The products are routinely validated with observations in order to assess their quality.
Data and products implementation and organization, as well as service for the users has been well tried and tested and most of the products are now available

to the users. The interaction with different users is an important factor in the development process.
This paper provides a synthetic overview of the GODAE Oceanview prediction systems
