| Summary: | Data supporting the paper: Land-Miller, H., A. Roos, M. Simon, R. Dietz, C. Sonne, S. Pedro, A. Rosing-Asvid, F. Rigét, and M. McKinney. 2023. Comparison of feeding niches between Arctic and northward moving sub-Arctic marine mammals in Greenland. Marine Ecology Progress Series. This data is in five files: 1. greenland_marmam_metadata.csv contains metadata for all samples used in this project, including sample identifiers: Sample: unique sample ID per individual animal Species and details of collection, including Year, Location (general area), Lat, Long, and Date. It also includes other data on the animal ( Sex, Age, Length ), when available, as well as the co-author who provided the sample to the project ( Sample sender ) and the tissues available/analyzed for each individual ( Tissues received ). 2. all_sample_locations.csv includeslatitude/longitude of each sample for mapping. Latitude and longitude areconsistent with the full metadata file when coordinates were available, and estimated based on general sampling area ( Location or Area ) when not. The variable estimate denotes samples for which coordinates were estimated. 3. fatty_acids_greenland_marmams.csv contains fatty acid data for all samples. Variables 8:00 to 24:1n9 represent the proportionof each individual fatty acid, out of total fatty acids in that sample. Data arerepresented as whole number percents (i.e., 10 = 10% and all fatty acids sum to 100 for each sample). 4. CNS_greenland_McGill.csv contains bulk stable isotope data for all samples analyzed at McGill. In addition to Sample and Species , this includes: treatment : whether a sample was lipid-extracted ( LE ) or non-lipid-extracted ( nLE ) prior to analysis d15N : stable isotope ratioδ 15 N d13C: stable isotope ratioδ 13 C d34S: stable isotope ratioδ 34 S perc.C: mass percent of carbon in the sample perc.N: mass percent of nitrogen in the sample perc.S: mass percent of sulfur in the sample C.N.ratio: mass ratio of carbon to nitrogen in the sample 5. CN_greenland_nLE_copenhagen.csv contains ...
