Abstract

Spatial variations of the nutrient concentration along the northwestward stream from the Bering Sea to the Chukchi Sea are considered for dissolved inorganic phosphorus (DIP) based on data from two surveys conducted in early September 2010 and 2020. The water mass from the Bering Sea has higher DIP than Chukchi Sea water, but in the upper layer its phosphorus is gradually lost due to both mixing with local water and consumption for photosynthesis. In the subsurface layer, the decrease in DIP is prevented by its recycling from degraded organic matter. The fluxes of phosphorus are estimated separately using the balance model with TS analysis, previously used in estuarial studies. Successive DIP utilization along the stream is traced, which forms in the Chukchi Sea two zones of high productivity divided by a wide low-productive zone. Nutrients from the upper layer are utilized within the southwestern Chukchi Sea, resulting in primary production 0.1–0.2 gC m^–3 day^–1, but the main stock of allochthonous nutrients from the subsurface layer is utilized further downstream (at Wrangel Island or in the northern Chukchi Sea) and results in production of 0.3–0.4 gC m^–3 day^–1. Localization of high-productive zones is determined by density stratification, which possibly depends on the stream strength: the stronger the advection through Bering Strait, the farther from the strait both zones are located. The recent tendency of strengthening of the stream tends to remove the zones of utilization the nutrients of Pacific origin from the southwestern Chukchi Sea.

以矿物磷为例说明通过白令海峡进入西南楚科奇海的营养物质的利用情况

摘要根据 2010 年和 2020 年 9 月初进行的两次调查数据，研究了从白令海到楚科奇海的西北流沿岸营养物浓度的空间变化，并对溶解性无机磷（DIP）进行了分析。白令海水体的 DIP 值高于楚科奇海水体，但在上层，由于与当地水体的混合以及光合作用的消耗，白令海水体的磷逐渐流失。在次表层，由于降解有机物的再循环，DIP 的减少得以阻止。磷的通量是利用以前在河口研究中使用的带 TS 分析的平衡模型分别估算的。沿溪流追踪了 DIP 的连续利用情况，这在楚科奇海形成了两个高生产力区，由一个宽阔的低生产力区分割开来。来自上层的营养物质在楚科奇海西南部被利用，导致初级生产力为 0.1-0.2 gC m-3 day-1，但来自次表层的主要异源营养物质则在更下游（弗兰格尔岛或楚科奇海北部）被利用，导致生产力为 0.3-0.4 gC m-3 day-1。高产区的位置由密度分层决定，密度分层可能取决于海流强度：流经白令海峡的海流越强，两个高产区的位置就离白令海峡越远。最近气流增强的趋势往往会将太平洋营养物质利用区从楚科奇海西南部移走。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
