This article presents readers with a set of concepts and definitions related to marine pollution produced by oil spills at sea. The types of existing emergencies identified by the main regional and global organizations dealing with the issue are mentioned. The main accidents that have occurred around the world in the last 20 years are reviewed, as...

Figures of the outputs of the oil slick trajectory simulations performed with the PETROMAR-3D model in northeastern Brazil in the months of January, April, July and October. During the evolution of the simulated slick, emphasis is placed around its center of mass and virtual particles that impact on coastline as two aspects to consider by user (or...
Technical Report
Full-text available
This technical note presents the graphical outputs of the lagrangian model PETROMAR-3D, version 2.1G, specialized to assume the operative work before real spills and to obtain statistical results before climatic executions. The scenarios were created in the waters adjacent to the Brazilian NE, with simulation times of thirty days, every 3 hours in...

Este trabajo muestra una reflexión vinculada a los Problemas de la Ciencia, la Tecnología y la Sociedad. Se presenta el modelo PETROMAR-3D (desarrollado en el Instituto de Meteorología de Cuba) en sus dos variantes de modelación: numérica y probabilística. Bajo el enfoque de la innovación tecnológica, se describe el estado actual del monitoreo de d...
Article
Full-text available
The version 2.1 of PETROMAR-3D model, created in the Center for Marine Meteorology of the Meteorology Institute of Cuba, is presented. This Lagrangian model has been designed to describe the physical processes of marine oil spills in the face of multiple scenarios of the marine environment. Although it is applicable to any part of the world, it is...
Article
Full-text available
This article shows the probabilistic modeling of hydrocarbon spills on the surface of the sea, using climatology data of oil spill trajectories yielded by applying the lagrangian model PETROMAR-3D. To achieve this goal, several computing and statistical tools were used to develop the probabilistic modeling solution based in the methodology of Guo....
Technical Report
Full-text available
Se muestra la modelación probabilística de derrames de hidrocarburos a través del desarrollo de nuevas características que aumentan la funcionalidad del modelo determinista de enfoque lagrangiano PETROMAR-3D, la cual es de suma importancia para el estudio de peligros de derrames de petróleo en las zonas costeras de Cuba. Para este propósito y luego...

The work begins with an analysis of the background of the topic, from expeditions and diagnoses carried out by multiple institutions in the region. The statistic contains the data of the NOAA project, called COSTWATCH, which calculates the geostrophic marine current from altimetry values. The download was automated to reduce subjective errors and t...

Este informe resume el trabajo realizado para hacer la transferencia de la plataforma BioMA a Cuba y sus primeras aplicaciones para evaluar los impactos del cambio climático y de opciones de adaptación del agro-manejo. Estos trabajos fueron conducidos en el contexto del proyecto BASAL Proyecto Bases Ambientales para la Sostenibilidad Alimentaria Lo...
Presentation
Full-text available
In this work is applied the Total Variation method (TVM) to approximate the derivative of functions specified by noisy data. This problem appears frequently in different branches of science and engineering, and the application of finite differences method or remove the noise from the data retrieve unsatisfactory results. The TVM is the minimization...

Full-text available
The “lid-driven cavity” problem is a fluids physics problem that can be modelled with Stokes equation system for incompressible fluids. These equations are of the elliptic type and is well known that for those equations the finite elements method is widely used to solve them. In this paper we deduce the weak formulation of the problem, we show the...
