attribute	NC_GLOBAL	acquisition_description	String	Otolith element concentrations for each individual fish (labeled as \u201cHMU ####\u201d) were measured at the University of Austin, Jackson School of Geosciences using laser ablation inductively coupled mass spectrometry.\u00a0 Standard reference materials included a National Institutes of Standards and Technology glass standard (NIST-612) and a United States Geological Survey microanalytical carbonate standard pressed pellet (MACS-3). Otolith element concentrations were quantified along the longest dorso-ventral axis spanning the core (i.e. hatch) to the edge (i.e. death). Please reference Altenritter et al. (2018) and Altenritter and Walther (2019) for detailed information on sampling and analysis, instrumentation, and data processing. \u00a0

attribute	NC_GLOBAL	projects_0_description	String	Description from NSF award abstract: Hypoxia occurs when dissolved oxygen concentrations in aquatic habitats drop below levels required by living organisms. The increased frequency, duration and intensity of hypoxia events worldwide have led to impaired health and functioning of marine and freshwater ecosystems. Although the potential impacts of hypoxic exposure are severe, there is little known about the consequences of systemic, sub-lethal exposure to hypoxic events for populations and communities of fishes. The objective of this project is to determine whether sub-lethal exposure to hypoxia during early life stages leads to poor growth and hence increased mortality. This project will use "environmental fingerprint" methods in fish ear stones (otoliths) retrospectively to identify periods of hypoxia exposure. The project will compare consequences of hypoxia exposure in different fish species from the Gulf of Mexico, the Baltic Sea, and Lake Erie, thus examining the largest anthropogenic hypoxic regions in the world spanning freshwater, estuarine, and marine ecosystems. This project will employ long-term, permanent markers incorporated into fish otoliths to identify life-long patterns of sub-lethal hypoxia exposure far beyond time spans currently achievable using molecular markers. This work will capitalize on patterns of geochemical proxies such as Mn/Ca and I/Ca incorporated into otoliths and analyzed using laser ablation inductively coupled plasma mass spectrometry to identify patterns of sub-lethal hypoxia exposure. The investigators will then determine whether exposure results in differential growth and survival patterns compared to non-exposed fish by tracking cohorts over time and identifying characteristics of survivors. Because this work involves multiple species in multiple hypoxic regions, it will allow cross-system comparisons among unique ecosystems. The results from this project will thus provide unprecedented insight into effects of hypoxia exposure in three major basins using novel biogeochemical proxies, thereby paving the way for a fuller understanding of the impacts of "dead zones" on coastal resources.
