Ecological Insights Into the Extinct Korean Sea Lion (Zalophus japonicus) in Korea Based on Stable Isotope Analysis of Bone Collagen. [PDF]
ABSTRACT Rationale The Japanese sea lion (Zalophus japonicus), once abundant in Japan, Korea, and Russia, went extinct by the mid‐20th century due to hunting and environmental change. This study examines the diet and ecological role of Korean Z. japonicus using stable carbon and nitrogen isotope analysis of bone collagen from archaeological and ...

Diurnal tides over Kashevarov Bank, Okhotsk Sea [PDF]
Diurnal tidal waves K1 and O1 were studied using a primitive equation ocean circulation model with fine vertical resolution. The study focused on Kashevarov Bank, a shallow submarine bank at the northern continental slope of the Sea of Okhotsk. Owing to resonance, the currents over the bank are 20–30 times stronger than the off‐bank currents. The large

On the origin of the North Pacific arcs [PDF]
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

NEOTECTONICS OF THE SEA OF OKHOTSK
The analysis of the neotectonic structure of the region is usually accompanied by the compilation of neotec‐ tonic maps and schemes. Models of the summit surface serve as the initial material for compiling different‐scale neo‐ tectonic maps and schemes [Ufimtsev, 1984].The summit surface is one of the main properties of the Earth's recent topography ...

New record of the monostiliferous hoplonemertean Gurjanovella littoralis Uschakov, 1926 from Japan (Nemertea, Hoplonemertea, Monostilifera) [PDF]
A single specimen of a monostiliferous hoplonemertean, collected from a depth of 25 m in Akkeshi Bay, northern Japan, represents the first record of Gurjanovella littoralis Uschakov, 1926 from the Northwest Pacific.

Production in the Sea of Okhotsk [PDF]
Primary production, microbial production and the density of planktonic microheterotrophs were estimated at 40 stations in the Okhotsk Sea in July-August 1992 during the seasonal phyto- plankton minimum. The primary production by phytoplankton remained rather high even during this minimum.

Age of ice in the Okhotsk Sea in 2001–2019 is determined by analysis of satellite data from passive and active microwave spectroradiometers. The areas with certain age composition are contoured with monthly discreteness.
