“…As “transitional waters” (McLusky and Elliot, 2007), estuaries link continental and marine biomes and facilitate exchanges of nutrients, organic matter, biota, and sediments (Baird and Ulanowicz, 1993; Elliott and Whitfield, 2011). Extant estuaries have formed over the past 8000 years in response to reduced rates of sea-level rise during the middle to late Holocene (Cronin et al ., 2007; Punwong, Selby, and Marchant, 2018; Tanabe, Nakashima, and Mizuno, 2022). Across subsequent millennia, human societies inhabiting transgressing estuarine zones developed coastal lifeways marked by population aggregation, sedentism, and sociopolitical stratification (Bailey and Milner, 2003; Gamble, 2017; Grier, 2014; Pluckhahn and Thompson, 2018; Riddick et al ., 2022).…”
