Cornillon Graduate School of Oceanography, University of Rhode Island, USA Email: [email protected] The Pathfinder AVHRR sea surface temperature (SST) data from 1985–1996 were processed with the Cayula-Cornillon edge detection and declouding algorithms. The following 11 fronts were distinguished: West Kamchatka, TINRO Basin, North and South Shelikhov Bay, North, West, Shantar, East Sakhalin, Central, Kashevarov Bank and Soya fronts. The large-scale pattern of these fronts is consistent with the dominant cyclonic circulation of the Okhotsk Sea. The West Front, TINRO Basin Front, Central Front and Shelikhov Bay Fronts have not been identified before. The West Kamchatka and TINRO Basin fronts form a double front observed in winter only. The North Front continues farther west than it was known, up to 146°E, where it likely connects to the West Front, which often joins the Shantar Front. The latter extends from Shantar Islands to Sakhalin Bay where the Amur River Plume interrupts a nearly continuous line of fronts around the northern and western Okhotsk Sea. The Amur discharge feeds the East Sakhalin Front that follows the shelf break, branches eastward at 48°N and 46°N, and eventually merges with Soya Front, which exits the sea via Vries Strait. The 48°N branch of the East Sakhalin Front seems to join the Central Front, which in turn merges with the TINRO Basin Front, thus forming the southern limb of the sea-wide frontal pattern. The Kashevarov Bank Front likely consists of three separate fronts around the namesake bank, St. Iona Island and Iona Bank. Fronts are seasonally persistent: they emerge and disappear in certain seasons in the same locations. Dominant frontogenetic mechanisms in the Okhotsk Sea are tidal mixing, water mass formation and advection, river discharge, and wind upwelling. Most fronts are generated owing to tidal mixing. Front genesis in the marginal ice zone and around polynyas is likely important; although these processes have not yet been investigated by in situ measurements.

  • Fronts in the World Ocean's Large Marine Ecosystems. ICES CM 2007
    - 1 - This paper can be freely cited without prior reference to the authors International Council ICES CM 2007/D:21 for the Exploration Theme Session D: Comparative Marine Ecosystem of the Sea (ICES) Structure and Function: Descriptors and Characteristics Fronts in the World Ocean’s Large Marine Ecosystems Igor M. Belkin and Peter C. Cornillon Abstract. Oceanic fronts shape marine ecosystems; therefore front mapping and characterization is one of the most important aspects of physical oceanography. Here we report on the first effort to map and describe all major fronts in the World Ocean’s Large Marine Ecosystems (LMEs). Apart from a geographical review, these fronts are classified according to their origin and physical mechanisms that maintain them. This first-ever zero-order pattern of the LME fronts is based on a unique global frontal data base assembled at the University of Rhode Island. Thermal fronts were automatically derived from 12 years (1985-1996) of twice-daily satellite 9-km resolution global AVHRR SST fields with the Cayula-Cornillon front detection algorithm. These frontal maps serve as guidance in using hydrographic data to explore subsurface thermohaline fronts, whose surface thermal signatures have been mapped from space. Our most recent study of chlorophyll fronts in the Northwest Atlantic from high-resolution 1-km data (Belkin and O’Reilly, 2007) revealed a close spatial association between chlorophyll fronts and SST fronts, suggesting causative links between these two types of fronts.

  • Sediment Transport to the Laptev Sea-Hydrology and Geochemistry of the Lena River
    Sediment transport to the Laptev Sea-hydrology and geochemistry of the Lena River V. RACHOLD, A. ALABYAN, H.-W. HUBBERTEN, V. N. KOROTAEV and A. A, ZAITSEV Rachold, V., Alabyan, A., Hubberten, H.-W., Korotaev, V. N. & Zaitsev, A. A. 1996: Sediment transport to the Laptev Sea-hydrology and geochemistry of the Lena River. Polar Research 15(2), 183-196. This study focuses on the fluvial sediment input to the Laptev Sea and concentrates on the hydrology of the Lena basin and the geochemistry of the suspended particulate material. The paper presents data on annual water discharge, sediment transport and seasonal variations of sediment transport. The data are based on daily measurements of hydrometeorological stations and additional analyses of the SPM concentrations carried out during expeditions from 1975 to 1981. Samples of the SPM collected during an expedition in 1994 were analysed for major, trace, and rare earth elements by ICP-OES and ICP-MS. Approximately 700 h3freshwater and 27 x lo6 tons of sediment per year are supplied to the Laptev Sea by Siberian rivers, mainly by the Lena River. Due to the climatic situation of the drainage area, almost the entire material is transported between June and September. However, only a minor part of the sediments transported by the Lena River enters the Laptev Sea shelf through the main channels of the delta, while the rest is dispersed within the network of the Lena Delta. Because the Lena River drains a large basin of 2.5 x lo6 km2,the chemical composition of the SPM shows a very uniform composition.

McDevitt • Dmitry Gorenburg Cleared for Public Release IRP-2013-U-002322-Final February 2013 Strategic Studies is a division of CNA. This directorate conducts analyses of security policy, regional analyses, studies of political-military issues, and strategy and force assessments. CNA Strategic Studies is part of the global community of strategic studies institutes and in fact collaborates with many of them. On the ground experience is a hallmark of our regional work. Our specialists combine in-country experience, language skills, and the use of local primary-source data to produce empirically based work. All of our analysts have advanced degrees, and virtually all have lived and worked abroad. Similarly, our strategists and military/naval operations experts have either active duty experience or have served as field analysts with operating Navy and Marine Corps commands. They are skilled at anticipating the “problem after next” as well as determining measures of effectiveness to assess ongoing initiatives. A particular strength is bringing empirical methods to the evaluation of peace-time engagement and shaping activities. The Strategic Studies Division’s charter is global. In particular, our analysts have proven expertise in the following areas: The full range of Asian security issues The full range of Middle East related security issues, especially Iran and the Arabian Gulf Maritime strategy Insurgency and stabilization Future national security environment and forces European security issues, especially the Mediterranean littoral West Africa, especially the Gulf of Guinea Latin America The world’s most important navies Deterrence, arms control, missile defense and WMD proliferation The Strategic Studies Division is led by Dr.

Photo: Erling Frantzen Courtesy of TGS BP/Rosneft Pela Lache OKHA SAKHALIN Yuzhno-Sakhalinsk The Sea of Okhotsk is named after Okhotsk, the first Russian settlement in the Far East. It is the northwest arm of the Pacific Ocean covering an area of 1,528,000 sq km, lying between the Kamchatka Peninsula on the east, the Kuril Islands on the southeast, the island of Hokkaido belonging to Japan to the far south, the island of Sakhalin along the west, and a long stretch of eastern Siberian coastline along the west and north. Most of the Sea of Okhotsk, except for the area around the Kuril Islands, is frozen during from November to June and has frequent heavy fogs. In the summer, the icebergs melt and the sea becomes navigable again. The sea is generally less than 1,500m deep; its deepest point, near the Kuriles, is 3,363 m. Fishing and crab- bing are carried on off W Kamchatka peninsula. The DMNG/TGS Seismic acquired in 1998, 2004 and 2005 is shown in green, blue and red colours.

The approach taken was to compare the status and population trends of stocks of key cetacean species in three areas with E&P activities―Alaska (subdivided into three regions, the Beaufort, Bering and Chukchi seas), Australia (Western and southeast regions), and Sakhalin Island, Russia―with corresponding parameters for stocks of the same species (where possible) in areas where E&P activities were absent or greatly reduced. The project involved a critical review of existing and historical data on cetacean stocks, and a compilation of data on E&P activities and non-industry factors that may have influenced stocks, in the areas of interest. Data were assessed in terms of quality, quantity, and temporal and spatial coverage to determine whether sufficient data were available for a reasonable assessment of correlations between cetacean populations and E&P activities.
