摘要

摘要2017年8月底/ 9月初，飓风哈维在美国德克萨斯州中部沉积了90×109立方米的雨水。在2017年6月、8月、9月和11月的四次巡航中，我们观察了德克萨斯州沿海水域的水文、营养物质和氧气浓度的变化。尽管陆地径流强烈，但沿海海洋的营养供应是短暂的，浮游植物生长很少，也没有缺氧。观察表明，这可能与沿岸海湾中营养物质的保留和从海湾中冲走的营养物质的浮游植物的快速吸收有关，也可能与大量雨水的稀释和沉积物中缺乏重要的碳储量有关，尽管有强烈的斜斜作用。到11月的巡航时，情况已经明显恢复正常，没有观察到长期影响。

The effects of Hurricane Harvey on Texas coastal-zone chemistry

Abstract. Hurricane Harvey deposited over 90×109 m3 of rainwater over central Texas, USA, during late August/early September 2017. During four cruises (June, August, September and November 2017) we observed changes in hydrography and nutrient and oxygen concentrations in Texas coastal waters. Despite intense terrestrial runoff, nutrient supply to the coastal ocean was transient, with little phytoplankton growth observed and no hypoxia. Observations suggest this was probably related to the retention of nutrients in the coastal bays and rapid uptake by phytoplankton of nutrients washed out of the bays, as well as dilution by the sheer volume of rainwater and the lack of significant carbon reserves in the sediments, despite the imposition of a strong pycnocline. By the November cruise conditions had apparently returned to normal, and no long-term effects were observed.

期刊介绍： Ocean Science (OS) is a not-for-profit international open-access scientific journal dedicated to the publication and discussion of research articles, short communications, and review papers on all aspects of ocean science: experimental, theoretical, and laboratory. The primary objective is to publish a very high-quality scientific journal with free Internet-based access for researchers and other interested people throughout the world. Electronic submission of articles is used to keep publication costs to a minimum. The costs will be covered by a moderate per-page charge paid by the authors. The peer-review process also makes use of the Internet. It includes an 8-week online discussion period with the original submitted manuscript and all comments. If accepted, the final revised paper will be published online. Ocean Science covers the following fields: ocean physics (i.e. ocean structure, circulation, tides, and internal waves); ocean chemistry; biological oceanography; air–sea interactions; ocean models – physical, chemical, biological, and biochemical; coastal and shelf edge processes; paleooceanography.
