Description

Model output and related files (described below) are available from the project website.

Monthly_Cij_Files_1996_2007.zip- Zip file containing monthly Lagrangian transition probability distributions from 1996 to 2007 from and to the 135 sites in the Southern California Bight. Results are provided as three-dimensional matrices (source_index, destination_index, advection_time) in Matlab .mat format.

Additional/Supplemental files:

ConnectivityMatrixManipulationExample.m– Matlab .m script file that calculates mean connectivity matrices for given advection time and estimates mean and minimum oceanographic times and from the monthly Particle Distribution Function (PDF) matrices. Will run on the unzipped monthly Cij folders with this program in the same directory.

plot_connect_funky.m- Matlab .m function that plots connectivity matrices with site locations.

site_centers.mat- Matlab .mat file of the latitude and longitude for the center for each of the 135 sites.

SBC_sites_map.pdf– graphical representation of the 135 sites around the Southern California Bight (also below).

Methods & Sampling

Model Output - Monthly_Cij_Files_1996_2007.zip: This zip file contains monthly Lagrangian transition probability distributions from 1996 to 2007 from and to the 135 sites in the Southern California Bight. Advection times range from 1 to 70 days, particles are water-following (no behavior) and particles are release at each source location averaged over the upper 30 m of the water column. Details of the calculations are provided in Mitarai et al. [2009] and Simons et al. [2013]. Results are provided as three-dimensional matrices (source_index, destination_index, advection_time) in Matlab .mat format. The monthly .mat files are organized into folders for each year. Each connect_MM.mat file contains one month of data with the MM referencing the months from 01-12.In each connect_MM.mat file is a 135x135x70 matrix called connect.Matrix. The matrix dimensions are 135x135x70 (i,j,k). The i-dimension is the index for the 135 destination sites. The j-dimension is the index for the 135 source sites. The i- and j-dimensions are probabilities. The k-dimension is the index for the advection time in days.
