In river-dominated deltas, where river discharge is sufficiently high, tidal amplitude is attenuated and distorted. Here we use wavelet analysis to examine the water level signal in stations located in wetlands adjacent to the main river outlet in the Wax Lake system, part of the Mississippi River Delta in Louisiana, USA. We study the signal attenuation in lateral wetlands at different frequency bands, following the propagation of the water level signal from the Gulf of Mexico to the innermost stations. During high river discharge, the astronomical tide measured inside the wetlands is reduced of 90\%{\textendash}98\% in comparison to the tide in Atchafalaya Bay. Storm surge events, largely occurring at lower temporal frequencies, propagate conserving their energy once the signal enters the delta mouth. The river discharge signal, mostly present at frequencies lower than 1.59 μHz, is felt depending on river discharge conditions and the station position within the wetlands. Our results suggest that lateral wetlands in the Wax Lake system act as a low pass filter, attenuating tidal components but not the low frequency components of storm surges.}, keywords = {Energy attenuation, storm surge, Tide, Wavelet transform analysis, wetland}, issn = {2169-9291}, doi = {10.1029/2021JC017655}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1029/2021JC017655}, author = {Nordio, Giovanna and Fagherazzi, Sergio} } @article {PIE492, title = {Improving predictions of salt marsh evolution through better integration of data and models.}, journal = {Annual Review of Marine Science}, volume = {12}, year = {2020}, note = {PI Synthesis}, pages = {389-413}, keywords = {disturbance, LTER-PIE, marsh accretion, marsh-edge erosion, morphodynamic modeling, sea level rise, sediment budget, storm surge}, doi = {10.1146/annurev-marine-010419-010610}, author = {Wiberg, P.L. and Fagherazzi, S. and Kirwan, M.L.} } @article {fernandes_declining_2018, title = {Declining Radial Growth Response of Coastal Forests to Hurricanes and Nor{\textquoteright}easters}, journal = {Journal of Geophysical Research: Biogeosciences}, volume = {123}, year = {2018}, pages = {832{\textendash}849}, abstract = {The Mid-Atlantic coastal forests in Virginia are stressed by episodic disturbance from hurricanes and nor{\textquoteright}easters. Using annual tree ring data, we adopt a dendroclimatic and statistical modeling approach to understand the response and resilience of a coastal pine forest to extreme storm events, over the past few decades. Results indicate that radial growth of trees in the study area is influenced by age, regional climate trends, and individual tree effects but dominated periodically by growth disturbance due to storms. We evaluated seven local extreme storm events to understand the effect of nor{\textquoteright}easters and hurricanes on radial growth. A general decline in radial growth was observed in the year of the extreme storm and 3 years following it, after which the radial growth started recovering. The decline in radial growth showed a statistically significant correlation with the magnitude of the extreme storm (storm surge height and wind speed). This study contributes to understanding declining tree growth response and resilience of coastal forests to past disturbances. Given the potential increase in hurricanes and storm surge severity in the region, this can help predict vegetation response patterns to similar disturbances in the future.}, keywords = {coastal vegetation, floods, LTER, storm surge, tree ring}, issn = {2169-8961}, doi = {10.1002/2017JG004125}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1002/2017JG004125}, author = {Fernandes, Arnold and Rollinson, Christine R. and Kearney, William S. and Dietze, Michael C. and Fagherazzi, Sergio} } @article {PIE446, title = {Declining radial growth response of coastal forests to hurricanes and nor{\textquoteright}easters}, journal = {Journal of Geophysical Research}, volume = {123}, year = {2018}, note = {Grad}, pages = {832-849}, keywords = {coastal vegetation, disturbance, floods, LTER-PIE, primary production, storm surge, tree ring}, doi = {10.1002/2017JG004125}, author = {Fernandes, A. and Rollinson, C.R. and Kearney, W.S. and Dietze, M.C. and Fagherazzi, S.} } @mastersthesis {PIE453, title = {The impact of extreme storm surges on Mid Atlantic coastal forests}, volume = {MS}, year = {2017}, note = {Grad}, school = {Boston University}, type = {mastersthesis}, address = {Boston, MA}, keywords = {coastal vegetation, disturbance, floods, LTER-PIE, primary production, storm surge, tree ring}, author = {Fernandes, A.} }
