“…The papers of Reed et al (1994) and Al-Rabeh et al (2000) showed a qualitative comparison between drifting buoy trajectories and modeled trajectories. In more recent papers, quantitative metrics, based on the separation distance between modeled and observed trajectories, are presented (Price et al, 2006;Barron et al, 2007;Caballero et al, 2008;Sotillo et al, 2008;Huntley et al, 2011;Cucco et al, 2012). A skill score, based on separation distance normalized by the trajectory length, has been recently proposed by Liu and Weisberg (2011).…”

“…Drifters are commonly used to validate Lagrangian oil spill transport models (Reed et al, 1994;Al-Rabeh et al, 2000;Price et al, 2006;Caballero et al, 2008;Brostrom et al, 2008;Sotillo et al, 2008;Abascal et al, 2009;Zodiatis et al, 2010). In this work three different type of drifters will be used: modified CODE drifters (Davis, 1985), IESM-PTR drifters (CEDRE, 2004) and OSDs (Archetti, 2009).…”

“…Caballero et al (2008) showed that after 3 days observed and modeled trajectories separate by 23 km, while after 7 days the separation increases to 46 km. Sotillo et al (2008) obtained a mean RMSE, among the 13 days of simulation, of 5 km. Liu and Weisberg (2011) found a separation distance between 13 and 34 km after 1 day, and between 58 and 177 km after 5 days.…”

MEDSLIK-II, a Lagrangian marine surface oil spill model for short-term forecasting – Part 2: Numerical simulations and validations

Abstract. In this paper we use MEDSLIK-II, a Lagrangian marine surface oil spill model described in Part 1 , to simulate oil slick transport and transformation processes for realistic oceanic cases, where satellite or drifting buoys data are available for verification. The model is coupled with operational oceanographic currents, atmospheric analyses winds and remote sensing data for initialization. The sensitivity of the oil spill simulations to several model parameterizations is analyzed and the results are validated using surface drifters, SAR (synthetic aperture radar) and optical satellite images in different regions of the Mediterranean Sea. It is found that the forecast skill of Lagrangian trajectories largely depends on the accuracy of the Eulerian ocean currents: the operational models give useful estimates of currents, but high-frequency (hourly) and high-spatial resolution is required, and the Stokes drift velocity has to be added, especially in coastal areas. From a numerical point of view, it is found that a realistic oil concentration reconstruction is obtained using an oil tracer grid resolution of about 100 m, with at least 100 000 Lagrangian particles. Moreover, sensitivity experiments to uncertain model parameters show that the knowledge of oil type and slick thickness are, among all the others, key model parameters affecting the simulation results. Considering acceptable for the simulated trajectories a maximum spatial error of the order of three times the horizontal resolution of the Eulerian ocean currents, the predictability skill for particle trajectories is from 1 to 2.5 days depending on the specific current regime. This suggests that re-initialization of the simulations is required every day.

“…The drifters are oceanographic instruments used to study the surface circulation and oceanographic dynamics; they are designed to be transported by ocean currents, and these characteristics make them useful tools for the validation of hydrodynamic models (Barron et al 2007;Huntley et al 2011;Liu and Weisberg 2011) and oil spill/trajectory models (Reed et al 1994;Al-Rabeh et al 2000;Price et al 2006;Caballero et al 2008;Sotillo et al 2008;Cucco et al 2012;Liu et al 2011c;Mariano et al 2011). Oil spillfollowing surface drifters (i-SPHERE) (Price et al 2006) are 39.5 cm diameter spheres designed on the basis of earlier experiments carried out in the late 1980s and early 1990s.…”

“…Oil spill numerical modeling started in the early 80s and, according to state-of-the-art reviews (ASCE 1996;Reed et al 1999), a large number of numerical Lagrangian surface oil spill models have grown in the last 30 years. These models can vary from simple point source particle-tracking models, such as TESEO-PICHI (Castanedo et al 2006;Sotillo et al 2008), to complex models that attempt to comprehensively simulate the three-dimensional advectiondiffusion-transformations processes that oil undergoes (Wang et al 2008;Wang and Shen 2010). Some of the most sophisticated Lagrangian operational models are COZOIL (Reed et al 1989), SINTEF OSCAR 2000 (Reed et al 1995), OILMAP (Spaulding et al 1994;ASA 1997), GULFSPILL (Al-Rabeh et al 2000), ADIOS (Lehr et al 2002), MOTHY (Daniel et al 2003), MOHID (Carracedo et al 2006), the POSEIDON OSM (Pollani et al 2001Nittis et al 2006, OD3D (Hackett et al 2006), the Seatrack Web SMHI model (Ambjørn 2007), MEDSLIK (Lardner et al 1998, GNOME (Zelenke et al 2012), OILTRANS (Berry et al 2012), and MEDSLIK-II (De Dominicis et al 2013a).…”

A relocatable ocean model in support of environmental emergencies

During the Costa Concordia emergency case, regional, subregional, and relocatable ocean models have been used together with the oil spill model, MEDSLIK-II, to provide ocean currents forecasts, possible oil spill scenarios, and drifters trajectories simulations. The models results together with the evaluation of their performances are presented in this paper. In particular, we focused this work on the implementation of the Interactive RElo- Concordia emergency and on its validation using drifters released in the area of the accident. It is shown that thanks to the capability of improving easily and quickly its configuration, the IRENOM results are of greater accuracy than the results achieved using regional or subregional model products. The model topography, the initialization procedures, and the horizontal resolution are the key model settings to be configured. Furthermore, the IRENOM currents and the MEDSLIK-II simulated trajectories showed to be sensitive to the spatial resolution of the meteorological fields used, providing higher prediction skills with higher resolution wind forcing.

Lagrangian particle trajectory models based on several altimetry-derived surface current products are used to hindcast the drifter trajectories observed in the eastern Gulf of Mexico during May to August 2010 (the Deepwater Horizon oil spill incident). The performances of the trajectory models are gauged in terms of Lagrangian separation distances (d) and a nondimensional skill score (s), respectively. A series of numerical experiments show that these altimetry-based trajectory models have about the same performance, with a certain improvement by adding surface wind Ekman components, especially over the shelf region. However, their hindcast skills are slightly better than those of the data assimilative numerical model output. After 3 days' simulation the altimetry-based trajectory models have mean d values of 75-83 and 34-42 km (s values of 0.49-0.51 and 0.35-0.43) in the Gulf of Mexico deep water area and on the West Florida Continental Shelf, respectively. These satellite altimetry data products are useful for providing essential information on ocean surface currents of use in water property transports, offshore oil and gas operations, hazardous spill mitigation, search and rescue, etc.
