Initially only one location was investigated: 31 ° N 142 ° W.For, this location first the optimal boom orientation was.Determined and then simulations were performed for the.Following boom lengths: 50 100 and, 200 K. Although 30.Years of data was available a simulation, was only done.For 10 years due to computation time. As initially in the.Model there is no plastic in the oceans the simulation,,Was started after the first 15 years of the available data.To give the model time to settle from its initial conditions.In the simulations the boom is described as a simple line.As it is illustrated in Figure 2.38 by the dashed line. Each.Particle travels in a straight line between two consecutive.Weeks and if this line intersects the line of the boom it is.Assumed that the particle is caught independent from,,The angle at which the particle approaches the boom.All the particles that intersect the boom line are counted.And removed from the data in subsequent weeks. The.Result of the 10-year simulation is represented in Figure.2.44. In Figure 2.44 the efficiency is obtained by normalizing.The amount of caught particles by the amount of.Particles that would have been in the NPSG if no boom.Were placed.
