Abstract The algae Saccharina latissima (Phaeophyceae) and bottom sediment were studied in two places of its habitat in the Zelenetskaya Bay of the Barents Sea: 1) in the zone of shipping traffic and ship parking (ZST&SP) and 2) algae plantations (AP) - the background part of the bay. According to the results of scanning electron microscopy and micro-X-ray spectral analysis, an active new formation of framboidal pyrite, iron oxides-hydroxides, and salt crystals were founded in the bottom sediment in the ZCST&SP of the bay. In the structure of the rhizoids of the thallom algae, inclusions of bottom sediment particles were revealed. The ICP MS method showed that the arsenic content in the S. latissima thallom significantly exceeds its level of presence in the bottom sediment. The maximum content of arsenic in algae from both habitats is determined in the rhizoids, and the lowest in the young part of the plate (meristem). The bottom sediment and thallom of S. latissima from the ZCST&SP contain two to three times more arsenic than the algae on the plantation.

First Time

A taxonomic review of the genus Anatoma Woodward, 1859 in the Eurasian Arctic seas is presented. The new species A. golikovi sp. nov. is described from the northwestern part of the Barents Sea. The species differs from all other Arctic and North Atlantic Anatoma in having a flat spire. We consider Anatoma schioettei Høisæter et Geiger, 2011, syn. nov., a junior synonym of A. crispata (Fleming, 1828). Anatoma schanderi Høisæter et Geiger, 2011 is recorded for the first time from the Siberian seas.

Svalbard comprises the islands between longs 10 to 35° E and between lats 74 to 81° N. The largest of these islands is Vestpitsbergen, followed by Nordaustlandet, Edgeøya, Barentsøya and Bjørnøya. The archipelago lies in the northwestern part of the Barents-Kara shelf. To south and east the continental shelf is covered by the shallow waters of the Barents Sea, whilst to the north and west the shelf falls away rapidly into the Arctic Basin and the Greenland Sea.

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.
