舟山六横岛附近海域海温监测管理数据

六横岛拥有大量的水产养殖基地，通过监测六横岛及其附近海域各观测点数据，了解海洋中的水温变化趋势和异常情况，并对海洋生态环境进行监测和评价，为六横岛海水养殖、海洋工程建设等工作，并为相关用海项目提供数据支撑。通过计算六横岛附近海域历年平均数值，作为海域水温历史基准数据，将当月该海域平均的水温数值与水温基准数据作比（海域当月平均水温数值/海域水温历史基准数据），得到该月该海域的水温指数，如水温指数在0.9-1.1的，则定义为“正常”，水温指数在1.1-1.2或0.8-0.9的，则定义为“预警”，水温指数在0.8以下或者1.2以上的，则定义为“异常”。

Liuheng Island boasts numerous aquaculture bases. This dataset collects and monitors data from various observation points in and around the waters of Liuheng Island, aiming to grasp the changing trends and abnormal conditions of seawater temperature, as well as monitor and assess the marine ecological environment, providing data support for seawater aquaculture on Liuheng Island, marine engineering construction and other related sea-use projects. Specifically, the multi-year average values of the adjacent waters of Liuheng Island are first calculated as the historical baseline data for seawater temperature. The seawater temperature index for a given month is derived by comparing the monthly average seawater temperature of the waters with the historical baseline, using the formula: Monthly Average Seawater Temperature / Historical Baseline Seawater Temperature. The index is categorized as follows: "Normal" when the index falls within 0.9–1.1; "Alert" when the index ranges from 1.1–1.2 or 0.8–0.9; and "Abnormal" when the index is below 0.8 or above 1.2.
