    The absorption and fluorescence properties of chromophoric dissolved organic matter (CDOM) are reported for the inner shelf, slope waters and outer shelf regions of the eastern Bering Sea during. Our Bering Sea research efforts continue, bolstered by the mass of data resources we have accumulated over many years. Our Bering Sea research areas stretch from Alaska’s west coast to the dateline (°). The Southeast Bering Sea Shelf was an early focus, which included the long-term mooring site M2.

    A coupled sea ice-ocean model, combined with observational and reanalysis data, is used to explore the seasonal predictability of the distribution and extent of cold bottom waters on the Bering Sea shelf through numerical simulations or statistical analyses.

    These phenomena over the Bering Sea Continental Shelf and Chukchi Sea continental shelf were observed by Tanaka et al. [34] and Timmermans et al. [35], respectively. These authors considered the. High primary productivity (plant growth) over the shelf results from the northward movement of nutrient-rich water entering the Bering Sea through the passes from the Gulf of Alaska onto the outer.

Abstract. This study examines climatological water properties over the southeastern Bering Sea shelf during Maps of surface and bottom temperature, surface and bottom salinity, and mixed­ layer depth are derived and presented for winter, spring, summer, and fall.

Surface tempemtures range from about -I to. lODe. over the year. Abstract. The Bering Sea is a unique subarctic water body that lies between 52° and 66°N and °E and °W (Fig.

A relatively small sea (1% of the world oceans), it contains approximately 10 6 km 3 of water. It is bounded on the north by the Chukotka and Seward peninsulas, with a narrow (85 km) shallow passage, the Bering Strait, connecting it to the Chukchi Sea and the.

The Bering Strait is characterized by a strongly advective physical regime that consists of three water masses (Anadyr Water, Bering Shelf Water and Alaskan Coastal Water.

The Bering Sea (Russian: Бе́рингово мо́ре, tr. Béringovo móre) is a marginal sea of the Pacific forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and The Americas.

On the Bering Sea shelf the ice is generated in the northern regions mainly in polynyas near coastal regions during offshore wind conditions and transported toward the outer shelf by winds. It would take a fully three-dimensional model of the Bering Shelf to reproduce these ice generation aspects and the circulation on the shelf.

Given the volume of the Bering Shelf and a typical shelf salinity of ~32, if only one-quarter of the Gulf of Alaska net glacial ablation were to enter the Bering Sea shelf via Unimak pass, we can account for a shelf-wide freshening of ± yr −1 (or about five times greater than the amount of freshening that the Yukon River appears.

The front is similar to those reported around the British Isles, but we find that in the Bering Sea the salinity distribution is. The influence of these passes is limited to the eastern Bering Sea shelf and plays virtually no role in modifying currents in the basin.

We next examine flow through the major passes in the Aleutian Arc (starting on the eastern side and moving westward), which strongly influence the flow patterns and water properties of the basin. Shelf Passes. - the thickening of ice over the winter - that in the early winter (i.e.

before day ) northflowing water carries no ice. J.D., K. Aagaard, C.H. Pease, and R.B. Tripp, Effects of a shelf polynya on flow and water properties in the northern Bering Sea, J. Geophys. Re-evaluation of water transports in the vicinity of Bering Strait, in.

Coachman et al. () described three water masses in the Bering Sea north of 62°N. Furthest west and most saline is Anadyr Water. Its high salinity is probably a result of salt excluded from ice formed during the winter on the Anadyr shelf.

Consequently, the source of most of the heat transported into the Arctic through Bering Strait is a result of air-sea interactions local to the northern Bering Sea.

Analysis of the currents and water properties on the southern shelf indicates that 50% of the shelf water is exchanged with slope water during October-January each year. Then this flow passes through the Shpanberg Strait to the northern part of the Bering Sea and joins the waters flowing through the Chirikov Strait forming the Bering Straight current carrying the water to the Arctic Ocean.

The circulation on the wide east Bering Sea shelf is predominantly in north-western and Northern direction.CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): The eastern Bering Sea shelf is a vast area with weak net circulation.

As a result, heat exchange with the atmosphere mainly accounts for changes in heat content of the water column. This region also has marked changes in atmospheric and water properties: for example, winds are light in summer but are relatively.The Bering Sea is quite stormy through much of most every winter.

But the nature of these storms varies a great deal. One type of atmospheric circulation pattern produces a parade of cyclonic, low-pressure systems from the southwest, and while the winds with these storm systems can be fierce, the air temperatures are relatively moderate, leading to a retreat in seasonal sea ice.
