  abstract = {{A}im{T}he goal of the study was to quantify changes in the extent of mangroves since the mid-twentieth century and to test the hypothesis that these changes are driven by ocean waves. {L}ocation{T}he pristine 300-km-long coast of {F}rench {G}uiana, {S}outh {A}merica. {M}ethods{W}e produced time series of mangrove maps using archival remote sensing images. {W}e retrieved significant wave heights ({H}-{S}), mean wave periods ({T}-{M}) and mean wave directions (({M})) from the {E}uropean {C}entre for {M}edium-{R}ange {W}eather {F}orecasts reanalysis products. {W}e used complex empirical orthogonal function ({CEOF}) decomposition to extract the main mode of mangrove surface area ({M}-{S}) variability and singular value decomposition ({SVD}) to test the relationships between {M}-{S} and {H}-{S},{T}-{M} and ({M}). {R}esults{T}he leading mode of variability extracted from the {CEOF} decomposition of {M}-{S} captured approximately 78% of the total auto-covariance and revealed multi-decadal fluctuations in {M}-{S} that were on the order of 10,000ha. {T}he {SVD} results indicated that the multi-decadal fluctuation in {M}-{S} cross-covaried with {H}-{S},{T}-{M} and ({M}) over the {N}orth {A}tlantic sector, particularly in the region immediately off the {F}rench {G}uiana coast that is remotely forced by the {N}orth {A}tlantic {O}scillation ({NAO}) during the winter season. {M}ain conclusions{W}e provide evidence based on linear statistics that variations in the extent of mangroves are driven by large-scale, low-frequency changes in {N}orth {A}tlantic waves that are related to the {NAO}. {S}uch a relationship is hypothesized to operate through wave pounding, which alters the mud substrates on which mangroves thrive and which varies with the phase of the {NAO}. {I}n addition to long-term trends due to anthropogenic climate change, our results stress the importance of studying low-frequency modes of climate variability to understand changes in the extent of mangroves.},
