Concurrent studies of the breeding ecology of Common Murres and Thick-billed Murres, Uria aalge and U. lomvia, on Hornøya, a colony in northern Norway, showed significant differences between the species in the timing of egg laying but no consistent differences in food choice, feeding frequency and rhythm, dive depth, or chick growth. Both species fed their chicks on capelin, Mallotus villosus, sand lance Ammodytes sp., and herring Clupea harengus. However, on Bear Island in the Barents Sea, the diet differed significantly, with Common Murre chicks being fed nearly exclusively capelin while Thick-billed Murre chicks received capelin, squid Gonatus fabricii, Arctic cod, Boreogadus saida, sculpins (Cottidae), shannies Lumpenus sp., and eelpouts (Zoarcidae). The lack of dietary segregation on Hornøya was in strong contrast with the results of earlier studies of sympatrically breeding murres and was probaby due to a near superabundance of food around the colony.

Expert Assessments

Identification of water masses in areas with complex water dynamics is a complex task, which is usually solved by the method of expert assessments. In this paper, it is proposed to use a formal procedure based on the application of the method of optimal multiparametric analysis (OMP analysis). The data of field measurements obtained in the 68th cruise of the R/V “Academician Mstislav Keldysh” in the summer of 2017 in the Barents Sea on the distribution of temperature, salinity, oxygen, silicates, nitrogen, and phosphorus concentration are used as a data for research. A comparison of the results with data on the distribution of water masses in literature based on expert assessments (Oziel et al., 2017), allows us to conclude about their close structural similarity. Some differences are related to spatial and temporal shifts of measurements. This indicates the feasibility of using the OMP analysis technique in oceanological studies to obtain quantitative data on the spatial distribution of different water masses.
