由美国地球物理联合会出版，作为海岸和河口研究的一部分，第58卷。缺氧是当溶解氧低于维持大多数动物生命所需的水平时发生的一种情况。在美国沿海水域和整个西大西洋，我们在路易斯安那州/德克萨斯州大陆架的墨西哥湾北部发现了最大的缺氧区。受影响的地区，在其最大范围内大约是新泽西州的大小，自1985年开始定期测量以来已经增加。来自低氧带的沉积物岩心也表明，藻类的生产和沉积以及氧胁迫在20世纪90年代早期要低得多，而在20世纪后半叶出现了显著的增加。我们在这样的测量背景下出版这本书，并回顾缺氧带的发展和扩大是如何影响这个大陆架上的生物资源的。
Published by the American Geophysical Union as part of the Coastal and Estuarine Studies, Volume 58. Hypoxia is a condition that occurs when dissolved oxygen falls below the level necessary to sustain most animal life. In U.S. coastal waters, and in the entire western Atlantic, we find the largest hypoxic zone in the northern Gulf of Mexico on the Louisiana/Texas continental shelf. The area affected, which is about the size of the state of New Jersey at its maximal extent, has increased since regular measurements began in 1985. Sediment cores from the hypoxic zone also show that algal production and deposition, as well as oxygen stress, were much lower earlier in the 190Os and that significant increases occurred in the latter half of the twentieth century. We publish this book against the background of such measurements, and to review how the developing and expanding hypoxic zone has affected living resources on this continental shelf.
