Sampling was conducted using four vessels operating almost concomitantly between February 21 and April 18 across the study region: the NOAA research vessel Bell M. Shimada; R/V CCGS Sir John Franklin; R/V TINRO; and the F/V Northwest Explorer. Trawl nets were deployed at each station in the top 50 meters of the water column and towed for 60 minutes (night) or 90 minutes (day) at 4 to 5 knots. A 2x2 cm sample of salmon muscle tissue was collected from above the lateral line and in front of the dorsal fin and stored at -80°C. Whole liver was collected immediately post-mortem and stored at -20°C until processing. Muscle and liver samples were then processed in the laboratory at the University of British Columbia. Muscle tissue was lyophilized in freeze drier for 48 hours, whereas liver samples were oven-dried at 50°C for the same duration. Dried tissue was homogenized using mortar and pestle, encapsulated in tin (Sn) capsules, and sent for measurements of carbon and nitrogen stable isotope ratios and elemental contents at an external lab. Samples were analysed on an Elemental Analyser coupled to an Isotope Ratio Mass Spectrometer. The data reported includes each sample ẟ13C, %C, ẟ15N, % N, and CN ratios, in addition to the metadata associated with each sample (e.g., coordinates of oceanographic station and bottom depth where salmon specimen was collected, etc.). Des saumons du Pacifique Nord (Oncorhynchus spp.) ont été capturés pendant les expéditions hivernales de l'Année internationale panpacifique des saumons en haute mer du Pacifique Nord, à l'hiver 2022. L'échantillonnage a été effectué à l'aide de quatre navires opérant presque simultanément entre le 21 février et le 18 avril dans la région étudiée : le navire de recherche de la NOAA Bell M. Shimada ; le R/V CCGS Sir John Franklin ; le R/V TINRO ; et le F/V Northwest Explorer. Des chaluts ont été déployés à chaque station dans les 50 premiers mètres de la colonne d'eau et remorqués pendant 60 minutes (nuit) ou 90 minutes (jour) à 4 à 5 nœuds. Un échantillon de 2 x 2 cm de tissu musculaire de saumon a été prélevé au-dessus de la ligne latérale et devant la nageoire dorsale et conservé à -80 °C. Le foie entier a été prélevé immédiatement après la mortem et conservé à -20 °C jusqu'au traitement. Des échantillons de muscle et de foie ont ensuite été traités dans le laboratoire de l'Université de la Colombie-Britannique. Les tissus musculaires ont été lyophilisés dans un lyophilisateur pendant 48 heures, tandis que les échantillons de foie ont été séchés au four à 50 °C pendant la même durée. Le tissu séché a été homogénéisé à l'aide d'un mortier et d'un pilon, encapsulé dans des capsules d'étain (Sn) et envoyé pour mesurer les rapports isotopiques stables du carbone et de l'azote et les teneurs en éléments élémentaires dans un laboratoire externe. Les échantillons ont été analysés sur un analyseur élémentaire couplé à un spectromètre de masse à rapport isotopique. Les données déclarées incluent chaque échantillon 13C, %C, 15N, % N et les ratios CN, en plus des métadonnées associées à chaque échantillon (par exemple, les coordonnées de la station océanographique et la profondeur du fond où le spécimen de saumon a été collecté, etc.). oceans true -146.98925,58.0040166666667 -140.930783,56.935733 -137.938216,54.9292 -132.092866,50.964166 -126.349166666667,47.7813833333333 -130.6276,46.7975 -135.0195,45.0185 -167.2317,45.4 -170.24799,47.12165 -173.6731,48.6787 -171.6187,50.2332 -165.3166,53.3027 -151.97805,56.47515 -150.996633333333,57.00005 -146.98925,58.0040166666667 0.0 56.0 5829 EPSG 2012-08-10 EPSG::5829 - Instantaneous Water Level height - Height relative to instantaneous water level uncorrected for tide.
