Otolith-derived hypoxia indices and tissue sulfur isotope data from Atlantic croaker in the Gulf of Mexico

Otolith chemistry-derived indices for hypoxia exposure for Age-0 Atlantic croaker in the northern Gulf of Mexico dead zone. Tissue stable isotope values (sulfur) are given for each fish. Full specimen capture and otolith chemistry analysis details are given in Altenritter & Walther 2019 (see reference). Carbon and nitrogen stable isotope data from the same fish can be found in the linked data set under "Related Materials".
