Biophysical models of persistent connectivity and barriers on the northern Mid-Atlantic Ridge

This contains four data files that are all matlab binary files (.mat)

all_vent_sites.mat

This is a Matlab data file containing the longitude (column 1), latitude (column 2), of all vent sites used in the simulations. Column 3 specifies whether a vent-site is a known vent site (=1) or a ghost vent-site (=0)

probeData_20W60W_04S45N.mat

This is a Matlab data file containing data on Argo probe cycles used to estimate average ocean currents that drive the particle tracking simulations. The variables in the file are:

• fl                      Argo float ID 
• depth              parking depth of the  Argo float    (m)
• longlatStart    longitude and latitude for the start of one dive cycle
• longlatEnd      longitude and latitude for the end of one dive cycle
• month             month of the dive cycle
• year                 year of the dive cycle
• timeStep         number of days between the start and end of a dive cycle
• distStep          distance between the start and end positions of a cycle (km)
• velocity           average velocity of the Argo float over one dive cycle (km/day)
• pos                  the mid-point position of the Argos float for each cycle

vent_connectivity_data.mat

This is a Matlab data file containing the connectivity data from the particle tracking simulations. The variables in this file are:

• bbox_all                 The coordinates for the 64 target boxes
• particleCount       The number of larval particles starting in each of the 64 target boxes. This should be 100000 for all target boxes
• connectTime         A 64x64x500 array giving number of particles making a connection between two target boxes. connectTime(i,j,t) = number of particles from box i that have passed though box j in a time <= t. The 500 times correspond to the vector tVec.
• leaveTime           A 64x500 array giving the time taken for particles to leave their initial target box. leaveTime(i,t) = number of particles starting in box i that leave the box in a time <=t. The 500 times correspond to the vector tVec.
• C_critical                Critical connection probability
• tVec                         A vector of simulation times. This should be 500 time points starting at day 1 up to day 500
• tMax                        The maximum simulation time (days)

sim_larval_dispersal.mat

This is a Matlab data file that contains the dispersal distances of all the simulated larval particles for six planktonic larval durations.  The variables in this file are:

• bbox_all    The coordinates for the 64 target boxes
• tMax           The maximum simulation time (days). This is the planktonic larval duration.
• distAll        The dispersal distance (km) within a given planktonic larval duration (tMax)
• startAll       The target box where a simulated larval particle started.  The position of this box is given by bbox_all
