Sea level regression during the Last Glacial Maximum exposed the Bering Land Bridge, and cut off the connection between the North Pacific and Arctic Ocean, ending the exchange of North Pacific Water through the Bering Strait. Exchange of North Pacific Water comprises a major portion of fresh water input to the Arctic Ocean, and is of vital importance to North Atlantic Deep Water formation, a vital component of Atlantic Meridional Overturning Circulation. Bering Strait throughflow thus plays an integral role in global climate stability. A suite of four cores was selected, three in the Bering Sea and one in the Chukchi Sea, to bracket the Bering Strait in order to elucidate changes in sediment delivery, productivity and regional oceanography as the Bering Land Bridge flooded and modern ocean circulation was established during the last deglaciation. The arrival of nutrient rich North Pacific Water in the Chukchi Sea is recorded around 8 ka by organic carbon isotope depletion and an increase in total organic carbon and organic nitrogen, reflecting an increasingly marine isotopic signal and increased productivity. In the Bering Sea, the early deglaciation is marked by depleted organic carbon isotopes that indicate increasing terrestrial input, and increased total organic carbon. Principal component analysis of sedimentologic, geochemical and isotopic data clearly captures discrete sediment populations that correspond to key climatic intervals, representing changes in sediment delivery, productivity and circulation during the last deglaciation. In the Bering Sea we observe that deglaciation began in earnest around 18–17 ka, but lack of confidence in our age control does not allow for a precise date. Our results suggest that modern circulation through the Bering Strait, and thus for the Bering and Chukchi Seas, was established ~8 ka. Prior to 8 ka there is an interval of sediment that appears record a possible reversal of flow through the Bering Strait corresponding to the 8.2 ka event.

Indiana University-Purdue University Indianapolis (IUPUI) / The global climate is creating more ice-free waters in the Arctic. These new navigation possibilities around the Arctic lead to increased global trade, tourism, and oil and gas exploration. With the foreseeable increased nautical transportation through the Northwest Passage, the United States needs to revisit its security posture in and around the Bering Strait. At least five different grand strategies are potentially relevant in addressing this question. By comparing the suggestions of these leading grand strategy approaches to what has actually been implemented by the United States in the Strait of Hormuz, the Strait of Malacca, and the Panama Canal, similarities emerge that can help the United States shape their strategy for the defending of its national interests in the Bering Strait. By testing the different grand strategies against three reasonably similar cases, I find that a forward military presence and supporting a liberal institutionalist approach are the two key aspects that the United States should employ in the Bering Strait. Increasing and improving the military presence that the United States has in the region should be a top priority. In addition, supporting the Arctic Council would provide an increased level of security to the United States and other nations in the region. This strategy is not without its challenges and it will require artful statecraft in order to be successful.

As Arctic warms twice as fast as the rest of the world and the polar ice-cap melts, the strategic importance and geopolitical significance of the Bering Strait as the only maritime gateway between the world's fastest-developing and dynamic regions, the Asia Pacific and the Arctic region, will steadily grow. The climate change triggered the reduction of the Arctic ice-cap, which results in increased maritime traffic activity as new shipping routes are becoming more viable and mineral resources more accessible. This has a tremendous impact on the region as it opens it to economic development but at the same time it puts strain on its fragile environment. The goal of the paper is to affirm that the geopolitical significance of the Bering Strait is increasing and will increase in the near future. The work examines the causes of the Bering Strait region's rise, its characteristics, challenges and opportunities together with the assessment of major regional actors' interests and approaches towards the region. Next, paper focuses The emphasis is put especially on the role of the United States and on their attitude toward the Bering Strait region. It therefore pays attention namely on the US policy and goals in the region, and on the implications the Strait's growing global importance has for the United...
