To facilitate comparison, we grouped coastal habitats into fjords, lagoons, shelves, and straits as four \u201ccoastscapes\u201d. We gathered over 12,000 rows of data collected over 24 years (between 1999 and 2022) from 34 different field campaigns across the coastal Arctic (63 to 81\u00b0N and 177\u00b0W to 33\u00b0E). Our goal was to examine the isotopic patterns in pelagic and sediment particulate organic matter (pPOM and sPOM, respectively) and four consumer groups (deposit feeders, opportunists\/scavengers, predators, and suspension feeders) among the four coastscapes. We found that despite the enormous spatial range of data, both pPOM and sPOM became 2.1\u2030 and 2.2\u2030 more\n                    <jats:sup>13<\/jats:sup>\n                    C-depleted per decade, respectively, with parallel decreases in the \u03b4\n                    <jats:sup>13<\/jats:sup>\n                    C values in consumers.
