Report of water masses receiving wastes from ocean dumping at the 106-mile dumpsite

The 106-Mile Dumpsite, a deep ocean site located 106 miles southeast of New York, receives sewage-treatment sludge from the municipallty of New York City. The site is occupied predominantly by slope water, however incursions of shelf water and warm-core rings occur periodically. Satellite infrared data are used to determine which water masses are present at the time of each dump. Records of sewage sludge dumping at the site are obtained from the Environmental Protection Agency (EPA). This report correlates data regarding volumes and dates of dumps at the site with information on the water masses present at each dump. It is the latest in a series of summaries covering the last fifteen years. A summary of the amounts of wastes received by each of the three principal water masses for 1991 is presented. In 1991, 1538.8 X 10⁶ gallons of sewage sludge were dumped at the 106-mile site. Approximately 72 percent (by volume) of the sludge was disposed of in slope water, 7 percent in shelf water, and the remalnlng 21 percent was received by warm-core rings. by Cynthia M. Ruhsam.

106英里倾倒场（106-Mile Dumpsite）是位于纽约东南方向106英里处的深海场址，接收来自纽约市市政当局的污水处理污泥。该场址的水体以斜坡水（slope water）为主，但陆架水（shelf water）和暖核环流（warm-core rings）会周期性侵入。研究人员通过卫星红外数据判定每次倾倒作业时在场的水团类型。该场址的污泥倾倒作业记录来自美国环境保护署（Environmental Protection Agency，EPA）。本报告将该场址的倾倒体积、日期数据与每次倾倒时在场的水团信息进行关联分析，是覆盖过去15年的系列总结报告的最新一篇。本文还给出了1991年三个主要水团各自接收的废物量汇总。1991年，共有1538.8×10⁶加仑的污水处理污泥被倾倒至106英里场址。其中约72%（按体积计）的污泥被处置在斜坡水中，7%被处置在陆架水中，剩余21%则由暖核环流接收。作者：辛西娅·M·鲁瑟姆（Cynthia M.
