Captions for Figures S1 to S6
Figure S1. Surface currents monthly average from the HYCOM climatology.
The colors indicate the current’s magnitude, and the arrows’ the current
direction.
Figure S2. Monthly climatological Lagrangian Coherent Structures. The
colors indicate the strength of attraction, where red is the strongest,
and white indicates low persistent stirring and isolated regions behind
a transport barrier.
Figure S3. Correlation matrix of the magnitude between each of the 8
SOMs spatial patterns from the HYCOM climatology (HC) and the 8 SOMs
spatial patterns from the HYCOM instantaneous time series (HI). Only
significant correlations are shown as different from zero.
Figure S4. Correlation matrix of the vector angle from each of the 8
SOMs spatial patterns from the HYCOM climatology (HC) and the 8 SOMs
spatial patterns from the HYCOM instantaneous time series (HI). Only
significant correlations are shown as different from zero.
Figure S5. Top panel is the BMUs for the climatological velocity (red
line), repeated each year of the time series for comparison, and the
BMUs for the instantaneous velocity (blue line) over 1994–2018. The
middle panel is a histogram of the difference between the two BMUs in
the top panel. The bottom panel is each year’s sum of differences other
than zero, the sum of the histogram in the second panel; the green line
is the 1994–2018 average.
Figure S6. The color contours are the density of trajectories points
that were initiated along the coastline of the Mexican Caribbean and
integrated back in time to find their provenance using HYCOM Global
instantaneous velocity of August 2018. Only the most attracting August
cLCS (black lines) are plotted (i.e. when their attraction strength is
above 1.2).
