На основании обширного материала впервые проведена корреляция нижнесреднепалеозойских стратиграфических подразделений местного ранга различных регионов Япономорской зоны перехода континент–океан. Выделены стратифицирующиеся и нестратифицирующиеся магматические комплексы этих возрастов, представляющие собой вулканические, субвулканические, вулканоплутонические и плутонические образования. Авторами детально рассмотрены территориально разрозненные в основном палеонтологически охарактеризованные разрезы ордовика, силура и девона данного региона. В структурах, наложенных на докембрийские массивы, рассматриваемые отложения обычно хорошо прослеживаются по латерали, в то время как в полициклических подвижных поясах они залегают часто в виде олистолитов в мезозойских микститах или крупных ксенолитов в разновозрастных гранитоидах. Субмаринные ордовикские, силурийские и девонские отложения ЯЗ накапливались в сходной палеогеографической обстановке практически в одних и тех же седиментационных бассейнах, которые соединялись с центральноазиатскими, приохотскими и австралийскими морями. Континентальные осадки исследованной территории представлены девонскими толщами, включающими многочисленные растительные остатки, широко распространенными также в Центральном Казахстане, Западной Сибири, Приохотье и Южном Китае. On the basis of extensive material the correlation of Lower – Middle Paleozoic local-rank stratigraphic divisions of the Sea of Japan Continent – Ocean Transitional Zone is carried out for the first time. The stratified and non-stratified magmatic complexes of these ages, representing volcanic, subvolcanic, volcano-plutonic and plutonic generations are allocated. The authors have considered territorially separate, generally paleontologically characterized Ordovician, Silurian and Devonian sections of the given region in details. In the structures superimposed on Precambrian Massifs, considered sediments are usually well traced along the strike, while in Polycyclic Mobile Belts they lie down often in the form of olistoliths in Mesozoic mixtites or – large xenoliths in uneven-aged granitoids. Submarine Ordovician, Silurian and Devonian sediments of JZ accumulated in similar paleogeographic conditions, practically in the same sediment basins, which incorporated to the Central-Asian, Okhotsk and Australian Seas. Continental deposits of the investigated territory are presented by the Devonian strata, including the numerous vegetative remnants, widespread as well in the Central Kazakhstan, Western Siberia, Okhotsk Region and in Southern China.

An overlapping (postvolcanic) ore mineralization of volcanic rocks building up submarine edifices in the Sea of Japan has been semi-quantitatively and qualitatively evaluated for the first time. The study considers the main types of volcanic rocks (marginal continental, post-rift, and alkali ones) and focuses primarily on mineral phases formed in them by nonferrous, noble, and rare metals. The most enriched are post-rift rocks. That is due to the initial magma’s fluid saturation, as well as long-lived volcanic and postvolcanic processes.

Abstract Negative Arctic Oscillation (AO) and western Pacific (WP) indices persisted from October to December 2012 in the Northern Hemisphere. For the first time, the monthly AO and WP were both negative for three consecutive months since records have been kept. Although in general negative AO and WP phases cause Siberia, East Asia, and Japan to be abnormally cold, Japan was relatively warm in October 2012 even though both the AO and WP were strongly negative. The temperature of the Sea of Japan reached a record-breaking high in October 2012, and it was found that heating by these very warm waters, despite the small size of the Sea of Japan, overwhelmed the cooling effect of the strongly negative AO and WP in October. Linear regression analyses showed that Japan tends to be warm in years when the Sea of Japan is warm. Consequently, the temperature over Japan is controlled by interannual variations of small-scale oceanic phenomena as well as by large-scale atmospheric patterns. Previous studies have ignored such small-scale oceanic influences on island temperatures.

Larval development of the symbiotic crab Sestrostoma balssi (Shen, 1932) (Varunidae: Gaeticinae) inhabiting Russian waters of the Sea of Japan is described and illustrated for the first time from material reared in the laboratory. The development includes five zoeal and a single megalopal stages. The first megalopa was attained at 20–22°C 35 days after hatching. The present paper is the first description of the complete larval development in the genus Sestrostoma. The larvae of S. balssi share all principal characters of the family Varunidae but are distinguished from the typical varunid larvae by the absence of a well-developed antennal exopod in the zoea and the presence of an 8-segmented antennal flagellum in the megalopa.

Larval development of the mud shrimp Upogebia issaeffi (Balss, 1913) (Decapoda: Gebiidea: Upogebiidae) is describedand illustrated for the first time from material reared in the laboratory. The development includes four zoeal and a singlemegalopal stages. At 20–22°C the first megalopa was attained 12 days after hatching. U. issaeffi is distinguished from U.major, the second upogebiid species inhabiting Russian waters of the Sea of Japan, by the presence of the fourth zoeal stage and considerably more intensive larval setation.

В статье на основе архивных источников и полевых исследований предлагается картирование и классификация девяти древних и средневековых укреплений бассейна р. Аввакумовки Восточного Приморья (Ольгинский район Приморского края). По геоморфологической характеристике укрепления относятся к мысовому, долинному и горному типам. Установлено, что фортификационные памятники создавались носителями разных культур (янковской, польцевской, мохэской, чжурчжэньской), датируемых I тыс. до н. э. – первой половиной II тыс. н. э. Впервые выявлено, что Михайловское городище относится к польцевской культуре эпохи Средневековья (VI в. н. э.). Расположение укреплений вдоль реки и ее притоков свидетельствует о функционировании здесь сухопутной и морской дорог. Сухопутная дорога спускалась с перевала к морю, морская магистраль пролегала вдоль побережья Японского моря. Based on archival sources and field research, the paper offers mapping and classification of nine ancient and medieval fortifications located in the Avvakumovka River basin in Eastern Primorye (Olga district of Primorye). Regarding their geomorphological characteristics, the fortifications are referred to promontory, valley and mountainous types. It has been discovered that the fortifications were built by people representing various cultures (the Yankovka, the Poltse, the Mohe, the Jurchen cultures) dating to I mill. BC – first half of II mill. AD. It has been established for the first time that the Mikhaylovskoye fortified settlement is attributed to the Poltse culture of the medieval period (6th century). The location of the fortifications along the river and its tributaries suggest existence of local overland and marine roads. The overland road descended from a mountain pass to the sea, whereas the marine road ran along the coastline of the sea of Japan.

A dichotomous identification key for brachyuran zoeal stages from Peter the Great Bay (Russian waters of the Sea of Japan) is provided for the first time. The key covers 16 taxa identified to species level and uses only the most conspicuous external characters of larvae that are easy to observe under a stereomicroscope without specimens dissection. The key is based on the accounts by various authors and new original descriptions of larvae obtained both from plankton samples and from laboratory culture. Brief descriptions of larvae of 16 brachyuran species are also included.

We report seven species of the genus Henricia Gray, 1840 that were found in Vostok Bay, and two species from adjacent area, known from museum collection or seen in underwater footage. while existing literature reported no confirmed species from this area. Most of these species: H. djakonovi, H. alexeyi, H. densispina, H. hayashii, H. granulifera, H. pacifica, H. asiatica, and H. oculata robusta were reported from the Sea of Japan previously. H. nipponica, known from Japan, is reported from Russian seas for the first time. All studied taxa are re-described here using a range of morphological characters and partial 16S rRNA nucleotide sequences, life colorations of several species are reported for the first time, and an identification key is provided. Lectotype designations are fixed for studied series of species described by AM Djakonov.
