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
