title: Data from: MarTurtSI, a global database of stable isotope analyses of marine turtles

description: Marine turtles are both flagship species of conservation concern and
 indicators of ocean health. As highly migratory species, and despite
 substantial research effort focusing on nesting females and satellite
 tagging studies, we still know little about the trophic ecology and
 habitat use of immature stages and males. Consequently, marine turtle
 biologists began using stable isotope analyses in the last decade to
 elucidate various aspects of trophic ecology, including habitat use and
 trophic position. This has resulted in a burgeoning but largely
 disconnected literature of mostly single-species case studies. Here we
 comprehensively synthesize this body of work into a unified data
 repository, the MarTurtSI database. MarTurtSI contains stable isotope data
 from six of seven marine turtle species ranging from juveniles to adults,
 in different developmental, feeding, and breeding habitats across multiple
 ocean basins. MarTurtSI will be curated and updated with the aim of
 enabling continued comprehensive and global investigations into the
 trophic ecology of marine turtles especially in the face of climate change
 and other conservation challenges.
