Abstract

The results of comprehensive studies of anthropogenic impacts caused by deep water discharge into coastal waters near the city of Sevastopol using an experimental model of a ground-space monitoring system are presented. The nature of anthropogenic pollution of the investigated basin associated with an emergency rupture of the collector of the discharge device with a design capacity of 43 800 thousand m³/year (from 2014 to 2018) and the situation after the elimination of the accident in 2019 were assessed based on an analysis of space data. The features of optical anomalies associated with the discharge of wastewater into the marine environment in the region of the collector rupture are revealed, which are manifested in the changes in the normalized indices of sea-surface color recorded from space multispectral images of various resolutions, ranging from 1.25 to 1.45, while the background values are ~1. After the recovery of the collector rupture in 2019, the values of these indices were close to 1. The length of the zone where intense pollution appeared is ~3.0 km and its width is ~0.8 km; the center of the zone is at the place of the collector rupture. Based on remote sensing data, a positive effect has been demonstrated associated with the repair, which is recommended based on the results of space monitoring.

从空间记录因排放收集器中断而造成的深水排入沿海水域的特征

摘要

提出了使用地面空间监测系统的实验模型对塞瓦斯托波尔市附近沿海水体深水排放造成的人为影响进行综合研究的结果。设计容量为43800000 m ³的排放装置集热器紧急破裂而导致的被调查盆地人为污染的性质每年（2014年至2018年）和2019年事故消除后的情况根据空间数据分析进行了评估。揭示了与收集器破裂区域中的废水排放到海洋环境有关的光学异常特征，表现为从各种分辨率的空间多光谱图像记录的海面颜色归一化指标的变化，范围从从1.25到1.45，而背景值为〜1。在2019年集热器破裂后恢复，这些指数的值接近1.出现严重污染的区域的长度为〜3.0 km，宽度为〜0.8 km; 该区域的中心在收集器破裂的位置。根据遥感数据，
