“…Oil spill models usually have a 3-D numerical model to calculate the pollutant transport (vertical movement), as well as its weathering (dispersion, evaporation, emulsification, dissolution, beaching and sedimentation). Oil spill operational models have proven to be particularly useful in accidents involving cargo ships (Perivoliotis et al, 2011;González et al, 2008;Breivik et al, 2011), thus becoming widespread during the last decades. Some of these operational systems have developed into Marine Security Decision Support Systems (DeSS) capable of use and exchange with other systems (e.g.…”

Abstract. This paper presents the structure and application of a regional scale operational modelling tool for the West Iberian coast, and discusses its potential for products and services for both scientific and coastal management activities. The forecasting suite includes nested hydrodynamic models forced with up-to-date meteorological forecast data and large-scale model results. The present status of the system and its recent upgrades are reviewed, offering a general description of the main components of the system: the forcing data, the circulation model, the model outputs and the validation methodology of model results. Seasonal differences in temperature, salinity and current velocity fields are illustrated and show satisfactory reproduction of the top and deep layer thermodynamics. The system provides boundary forcing for a number of local-scale model applications via downscaling of the solution and enables potential products and services from which civil society will benefit.

“…This report documents an ocean physical modelbased analysis of the March to July 2011 stranding events. Objects at sea drift in a complex way as a sum of the components of direct wind, wind-induced swells and waves (Stokes drift), and ocean currents (components reviewed by Breivik et al 2011). For sea turtle carcasses, the appropriate parameters and contribution of each component are unknown.…”

From March through July 2011, an increased number of Kemp's ridley sea turtles Lepidochelys kempii were reported stranded on the islands, beaches and shorelines of Louisiana, Mississippi and Alabama. Members of the National Sea Turtle Stranding and Salvage Network responded, documenting the location and physical condition of each turtle. This report describes an ocean physical model-based analysis of the spring and summer 2011 Mississippi stranding events. Included within this group of strandings was 1 satellite-tagged moribund Kemp's ridley turtle, initially alive and tagged by the Institute for Marine Mammal Studies for a site fidelity study. Data from this tracking event provided an accurate time sequence of 58 h, during which the animal was presumed to be drifting, based on observed characteristics that were typical of a floating carcass. Turtle drift data were combined with output from the America SEAS (AMSEAS) hydrodynamic model to provide an estimate of leeway. The AMSEAS model was then applied to an additional 247 stranded turtles to produce 5 d Lagrangian backtrack drifts to derive mortality source location probability maps. Based on the model presented in this study, the majority of mortalities appeared to have occurred in eastern Louisiana state waters.

“…The same formulation of these forces as applied in Daniel et al (2002) and Breivik et al (2011) to study drift of ship containers was adopted in this study, although justification for thin nearly horizontally floating objects ( Fig. 2) could be slightly different.…”

Consideration of various aspects in a drift study of MH370 debris

Abstract. On 7 March 2014, a Boeing 777-200ER aircraft operated by Malaysian Airlines as MH370 on the route from Kuala Lumpur to Beijing abruptly ceased all communications and disappeared with 239 people aboard, leaving its fate a mystery. The subsequent analysis of so-called satellite "handshakes" supplemented by military radar tracking has suggested that the aircraft ended up in the southern Indian Ocean. The eventual recovery of a number of fragments washed ashore in several countries has confirmed its crash. A number of drift studies were undertaken to assist in locating the crash site, mostly focusing either on the spatial distribution of the debris washed ashore or on the efficacy of the aerial search operation. A recent biochemical analysis of the barnacles attached to the flaperon (the first fragment found in La Réunion) has indicated that their growth likely began in water of 24 • C; then the temperature dropped to 18 • C, and then it rose up again to 25 • C. An attempt was made in the present study to take into consideration all these aspects. The analysis was conducted by means of numerical screening of 40 hypothetical locations of the crash site along the so-called seventh arc. Obtained results indicate the likelihood of the crash site to be located between 25.5 and 30.5 • S, with the segment from 28 to 30 • S being the most promising.
