Description:

Abstract:

Black-legged Kittiwakes and Thick-billed Murres were collected with a shotgun as they were foraging, or were associated with foraging flocks at sea. Specimens were frozen immediately and stomachs were removed upon return to land and sent to Kathy Turco in Fairbanks for analysis of hard and soft prey tissue contents. During this process, basic morphometrics were completed and recorded in this dataset presented.

Purpose:

Seabirds were collected for verification of prey species eaten by focal seabird study species included in the Patch Dynamics Study portion of the Bering Sea Research Project B67&B77

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Internationally-accepted isotope elemental calibration standards were used to determine accuracy (acetanilide, cyclohexanone, cystine, methionine, nicotinamide, sulfanilamide). Secondary isotopic reference materials included NIST bovine liver, and NIST mussel, as well as NIST pine needles, and NIST tomato leaves. Calibration runs were conducted frequently to check for run drift and linearity. Blanks were analyzed every twenty samples and Secondary isotopic reference materials were analyzed every ten samples.

Logical_Consistency_Report:

Data columns in spreadsheet were checked for outlying values, however it is known that many seabirds (kittiwakes, in particular) will at times scavenge human fish offal or processor wastes. Such behavior could influence isotopic values measured in tissues. It remains user’s discretion to define test criteria and identify outliers accordingly.

Completeness_Report:

Data are presented in complete, raw format, as delivered from lab

Methodology:

Methodology_Type: Lab

Methodology_Description:

Before testing, all samples were dried at 40°C for 48 h, then ground into a fine powder and lipid-extracted using a methanol-chloroform mixture (Bligh and Dyer, 1959, Sotiropoulos et al., 2004, Kojadinovic et al., 2008). Seabird tissues were analyzed at the University of Alaska Fairbanks. Fish and euphausiid tissues were analyzed at Northern Arizona University. Isotope values for δ13C and δ15N were measured with continuous-flow isotope-ratio mass spectrometry, using a Thermo-Electron Deltaplus Advantage gas isotope-ratio mass spectrometer interfaced with a Costech Analytical ECS4010 elemental analyzer. Internationally-accepted isotope elemental calibration standards were used to determine accuracy (acetanilide, cyclohexanone, cystine, methionine, nicotinamide, sulfanilamide). Secondary isotopic reference materials included NIST bovine liver, and NIST mussel, as well as NIST pine needles, and NIST tomato leaves. Calibration runs were conducted frequently to check for run drift and linearity. Blanks were analyzed every twenty samples and Secondary isotopic reference materials were analyzed every ten samples. Precision of secondary isotope reference material (n = 82) was < 0.25 ‰ for both carbon and nitrogen. Twice a year the Secondary isotopic reference materials from these labs are compared to NIST standards for quality assurance. The δ13C and δ15N values are expressed relative to Vienna-Pee Dee Belemnite limestone V-PDB for carbon, and to air for nitrogen. Stable isotopes are reported here in δ notation as the deviation from standards, in parts per thousand (‰), according to the following equation: δX = [(Rsample/Rstandard) – 1] where X is the isotope in question (15N or 13C) and R is the ratio of the heavier (e.g., 15N) to the lighter (e.g., 14N) isotope of the element (Fry, 2005).

Methodology:

Methodology_Type: Field

Methodology_Description:

Birds were collected with a shotgun while they foraged at sea within 200 km of the Pribilof Islands and extending down to within 200 km of Bogoslof Island. Flash frozen immediately, then dissected on land and feather, liver, and muscle tissues samples were removed and sent to University of Alaska Fairbanks for analyses.
