Abstract:
To differentiate Sakhalin saffron cod, 3 types of parasites can be used: Pyramicocephalus phocarum pl., Nybelinia surmenicola pl. and Echinorhynchus gadi. From a practical point of view, as a biological label for the differentiation of the navaga hall. It is advisable to use indicators of infection with Nybelinia surmenicola l in the south-east of Sakhalin and the north-west of the island. To determine the location of the catch of the navaga (applicable only for the areas of the north-west, south-east of Sakhalin and zal. Patience) it is necessary to examine at least 100 specimens of fish.

According to the WWLLN data for the period of 2009-2018, regional features of lightning activity in the south of the Russian Far East, including the southern part of Sakhalin Island, are investigated. It is shown that the thunderstorm period here (99.5% of lightning) is from May to September in the northern continental regions, from April/May to October in the southern and southeastern regions, and from May to November in the southern part of the island. It was noted that the lightning activity is characterized by the maxima in July over plains and lowlands and in June over the areas with pred

Abstract:
During the expedition of the Zoological Institute of the Russian Academy of Sciences (ZIN RAS) in 1998, a fossil impression of a polychaete worm belonging to the family Nephtyidae Grube, 1850, containing fragments of jaws, was found in the west of Sakhalin. The find is dated to the Middle and Upper Miocene. There are no published records of any finds of fossil nephtyids in the area. Based on the analysis of the jaw shape, it is concluded that the nephtyid impression may belong to the genus Nephtys Cuvier 1817 or the genus Aglaophamus Kinberg, 1865.

This oil-and-gas-bearing region is confined to the region of juxtaposition of the Pacific crust, pushed under Kamchatka, with the Okhotskplate. The lower layer of the Kamchatka crust with lower density is a source of thermal anomalies that provide optimal conditions for catagenesis of oil (temperature 120–130 °C) and gas (temperature 200–00 °C) deposits in the upper layers of the crust.

In the northern Sakhalin Island, the tectonic activity of the fault zones is a potential threat to the industrial infrastructure of the petroleum fields. Recently, the background seismicity has increased at the Hokkaido‐Sakhalin fault that consists of several segments, including the Garomai active fault. In the studies of the regional deformation processes, it is important not only to analyze the seismic activity, but also to quantitatively assess the dynamics of deformation accumulation in the fault zones. In order to study the contemporary geodynamics of the Garomai fault, a local GPS/GLONAS

Abstract The Soya “Warm Current” (SWC) flows through a shallow strait between the Japan Sea and the Sea of Okhotsk. The SWC has a jet structure downstream of the strait along the northern coast of Hokkaido with a maximum speed exceeding 1 m s−1 at its axis in summer and fall. A surface cold belt with a subsurface doming structure forms offshore of the SWC axis. Mechanisms of the cold belt formation are discussed from a point of view of resonant interaction between a barotropic stratified flow and a shallow sill and subsequent baroclinic adjustment along the SWC.
