The field data show that the ventilation of waters in the Sea of Okhotsk occurs the year round as a cyclic process and consists of several phases. During the initial phase, the shelf waters enter the offshore subsurface layers. Later, they appear at intermediate depths and spread southward as cold intrusions mixing with surrounding waters on their way. During the last phase of the cycle, the shelf waters do not penetrate the deep-sea layers, and in the vertical structure of temperature field near the northeast coast of Sakhalin, a local phenomenon of “warm” dichothermal layer is observed. 相似文献

The waters of the Bering and Chukchi seas, as well as the De Long Strait, are investigated based on the data obtained in August 2013 during the scientific expedition of the Far Eastern Floating University on the research vessel Professor Khlyustin. Chlorophyll a concentrations calculated from MODIS-Aqua and VIIRS satellite data by ocean color and obtained by means of shipboard flow-through fluorometric measurements are comparatively analyzed. Vessel data are corrected for standard spectrophotometric measurements and the vertical depth distribution of phytoplankton. It has been found that, in the waters of the Eastern Arctic, satellite radiometers showed overestimated chlorophyll a concentrations in the upper seawater layer visible from the satellite. This is associated with the additional contribution of colored dissolved organic matter in the sea surface color. In the De Long Strait, satellite measurements incorrectly estimate the depth integrated chlorophyll a concentration, since the bulk of phytoplankton cells at a chlorophyll a concentration of 10–20 g/L is at depths of 25–30 m with luminosity of 5%. 相似文献

Gas emissions from mud volcanoes on Sakhalin Island and water-column gas flares arising from cold seeps in the Okhotsk Sea appear to be related. They are likely activated by tectonic movements along the transform plate boundary separating the Okhotsk Sea Plate from the Eurasian and Amur plates. Gas vents (flares) and methane anomalies occur in the waters offshore Sakhalin Island, along with NE-SW-trending mounds and fluid escape structures on the seafloor. The intersection of the NE-striking transverse faults on land with the Central Sakhalin and Hokkaido-Sakhalin shear zones apparently determines the sites of mud volcanoes, a pattern that continues offshore where the intersection with the East Sakhalin and West Derugin shear zones determines the sites of the submarine gas vents. 相似文献

Results of data analysis, based on measurement of atmospheric concentrations of methane in the shallow part of the East Siberian
shelf (ESS) are presented in this work. It was shown that methane emission in the atmosphere is determined not only by natural
factors, but is also sensitive to anthropogenic influences, like the engine mode of a ship. It was determined that the hydraulic
impact, which occurs when starting a ship’s engine after drifting through a shallow, can induce a great methane outbreak in
the atmosphere. The power of these “short-lived” sources can exceed the power of any one deep-water mud volcano. In the shallow
parts of the ESS, the anthropogenic factor can be one of the important factors effecting methane outbreaks in the atmosphere. 相似文献

The thermohaline and hydrochemical characteristics of the Lena River’s estuarine zone were investigated in the Buor-Khaya
Bay and the southeastern Laptev Sea in September of 2005. A tongue of river water with high nutrient content and increased
turbidity was identified in the bay. It is shown that the two-layer structure in the bay is disturbed by warm freshwater lenses.
The strong vertical stratification in the shelf zone results in sharply contrasting characteristics of the surface and bottom
waters. It is established that the concentrations of biogenic elements regularly change depending on the thermohaline characteristics
of the waters and their stratification degree. Stagnant bottom waters with low dissolved oxygen contents and high concentrations
of phosphates, nitrates, and ammonium are recorded in the eastern part of the bay. The bottom waters have different hydrochemical
characteristics due to their different origin. 相似文献

Data of field observations are indicative of the periodic appearance of intrusions of cold water at depths of 250–400 m near the northeastern Sakhalin continental slope in summer. Monitoring of the oceanographic conditions in the area shows that the density contrast between shelf and offshore waters persists throughout the year. The static instability of the water column in the vicinity of shelf break and the continental slope is a permanent feature of the area during the year and is the main cause of ventilation of the Sea of Okhotsk water in summer. The energy of tides can be an additional drive for the penetration of shelf waters into the sea interior and modulate the ventilation process. 相似文献
