Few studies, to our knowledge, have examined temporal patterns in the soundscape of a mosaic of intertidal, estuarine habitats. These environments are essential fish habitat for ecologically important species, like the silver perch (<em>Bairdiella chrysoura<\/em>), and economically important species, like the spotted seatrout (<em>Cynoscion nebulosus<\/em>). Passive acoustics provides a cost-effective way to obtain information on biodiversity and habitat characteristics (e.g., structural complexity; diversity of habitat types) that are potentially critical for ecological management and fisheries research. Our objective was to provide a baseline soundscape characterization for Middle Marsh, within the Rachel Carson Estuarine Research Reserve, investigate temporal patterns in the summer soundscape and identify what processes and environmental variables influence temporal soundscape patterns across the reserve.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/cmast.ncsu.edu\/wp-content\/uploads\/sites\/16\/2020\/10\/DSCN0121-1024x768-1.png\" alt=\"\" class=\"wp-image-3962\" srcset=\"https:\/\/cmast.ncsu.edu\/wp-content\/uploads\/2020\/10\/DSCN0121-1024x768-1.png 1024w, https:\/\/cmast.ncsu.edu\/wp-content\/uploads\/2020\/10\/DSCN0121-1024x768-1-300x225.png 300w, https:\/\/cmast.ncsu.edu\/wp-content\/uploads\/2020\/10\/DSCN0121-1024x768-1-768x576.png 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Research Questions<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>What are the temporal soundscape patterns in an estuarine reserve<\/li><li>What processes drive those patterns?<\/li><li>How does the soundscape reflect fish habitat use?<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Study System<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"453\" src=\"https:\/\/cmast.ncsu.edu\/wp-content\/uploads\/sites\/16\/2020\/10\/Screen-Shot-2016-04-12-at-4.44.31-PM-600x453-1.png\" alt=\"\" class=\"wp-image-3961\" srcset=\"https:\/\/cmast.ncsu.edu\/wp-content\/uploads\/2020\/10\/Screen-Shot-2016-04-12-at-4.44.31-PM-600x453-1.png 600w, https:\/\/cmast.ncsu.edu\/wp-content\/uploads\/2020\/10\/Screen-Shot-2016-04-12-at-4.44.31-PM-600x453-1-300x227.png 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<p>This study characterized the summer soundscape of the Rachel Carson Estuarine Research Reserve in Beaufort, NC.
