35518 Shark Stable Isotope Data Entity Published / External 18593 Predator Gut Isotopes - Characterizing ecosystem role of sharks Data Set Planned Shark tissue stable isotope signatures from Northeast Pacific coastal habitats. Spreadsheet Yes PARR Shark tissue stable isotope signatures from Northeast Pacific coastal habitats. 1 Date_Processed DATE No No Active Date the tissue sample was processed in the laboratory. DATE 2 Sample_Number NUMBER No No Active Laboratory vial number. NUMBER 3 Sample_ID VARCHAR2 No No Active Sample identification number, generally consisting of the first initial of the Genus and species names, respectively, the last two digits of the sampling year, and the sequential number of the individual shark collected in that sampling year. VARCHAR2 4 Species VARCHAR2 No No Active Scientific name (http://www.fishbase.org/search.php). VARCHAR2 Hexanchus griseus, Notorynchus cepedianus, Squalus acanthius. 5 Tissue VARCHAR2 No No Active Tissue type; in this case, all samples consisted of white muscle tissue plugs collected by small 0.5 cubic cm biopsies. VARCHAR2 Muscle. 6 Preservation VARCHAR2 No No Active Tissue preservation method. VARCHAR2 Ethanol, Frozen. 7 d15N NUMBER No No Active Stable isotope ratio of carbon, expressed in typical delta notation form, where d13C = [(Rsample / Rstandard) - 1] 1000. In this equation, R is the ratio of 13C/12C isotope values; Rsample represents the tissue sample ratio and Rstandard represent the universal reference standard: PeeDee Belemnite. NUMBER 8 d13C NUMBER No No Active Stable isotope ratio of nitrogen, expressed in typical delta notation form, where d15N = [(Rsample / Rstandard) - 1] 1000. In this equation, R is the ratio of 15N/14N isotope values; Rsample represents the tissue sample ratio and Rstandard represent the universal reference standard: atmospheric nitrogen gas. NUMBER 9 C:N NUMBER No No Active Ratio of total carbon to total nitrogen in the sample tissue. NUMBER 10 Total_Length NUMBER No No Active Total length, defined as the length from the anterior-most part of the shark to the tip of the longest caudal fin. Units for values are cm. NUMBER cm 11 Weight NUMBER No No Active Total body weight. Units for values are kg. NUMBER kg 12 Sex VARCHAR2 No No Active Sex, as determined by external examination of claspers (http://nefsc.noaa.gov/nefsc/Narragansett/sharks/sexdet.html). VARCHAR2 Male, Female. 13 Collection_Location VARCHAR2 No No Active Location the shark was collected, generally based on place names (bays, points) in Washington State. VARCHAR2 14 Collection_Date DATE No No Active Date the tissue sample was collected from the shark.
