Real time history of wave parameters in Black Sea based on wave buoy measurements

Dataset of mean wave parameters registered every 30 min by spotter wave buoy (https://www.sofarocean.com/products/spotter) installed in Black Sea region near Gelendzhik city (Russia) on water depth about 80 m and about 4 nautical miles from the shore (LAT 44.510 LON 37.970). The buoy was installed at 23 July 2020 in the frame of integrated coastal-marine scientific expedition "Black Sea - 2020" of Shirshov Institute of Oceanology (State assignments 149-2019-0005 and 149-2019-0014). The dataset provide 30 min averaged time history (Epoch Time) of wave parameters from this date and each 30 minutes up to 1 November 2020. Following wave parameters are available: Significant Wave Height (m),Peak Period (s),Mean Period (s),Peak Direction (deg),Peak Directional Spread (deg),Mean Direction (deg),Mean Directional Spread (deg),Latitude (deg),Longitude (deg). Also there are calculated real time estimations of Wind Speed (m/s) and Wind Direction (deg) (https://www.sofarocean.com/posts/wind-spotter). The data are in columns separated by commas, a symbol “-“ means no data. Some notes on data quality. Data such as they are transmitted by the buoy without additional selection. Sometimes there are spikes of the wave period (about 14-20 s) associated with the recording of ship waves in the presence of small wind waves (significant waves up to 40 cm high). Sometimes there are significant spikes of the height of significant waves associated with the fact that curious sailors and fishermen can raise a buoy on board the ship to see what it is. On 27 August 2020, the buoy was torn away by a strong current and re-installed at the same location on 3 September 2020.本数据集为安装于俄罗斯格连吉克市附近黑海海域、水深约80米、距岸约4海里（纬度44.510°，经度37.970°）的Spotter波浪浮标（Spotter Wave Buoy，https://www.sofarocean.com/products/spotter）每30分钟记录的平均波浪参数数据集。 该浮标于2020年7月23日随希尔绍夫海洋研究所（Shirshov Institute of Oceanology）“黑海-2020”综合性海岸海洋科学考察任务布设，配套国家任务项目编号149-2019-0005与149-2019-0014。 本数据集涵盖自布设当日起至2020年11月1日止的每30分钟平均波浪参数时间序列（纪元时间，Epoch Time）。 本次公开的参数包含：有效波高（Significant Wave Height，单位：米）、峰值周期（Peak Period，单位：秒）、平均周期（Mean Period，单位：秒）、峰值波向（Peak Direction，单位：度）、峰值方向扩散度（Peak Directional Spread，单位：度）、平均波向（Mean Direction，单位：度）、平均方向扩散度（Mean Directional Spread，单位：度）、纬度（Latitude，单位：度）、经度（Longitude，单位：度）。此外还包含基于实时估算得到的风速（Wind Speed，单位：米/秒）与风向（Wind Direction，单位：度）相关数据（数据来源：https://www.sofarocean.com/posts/wind-spotter）。 数据集采用逗号分隔列存储，符号“-”代表无有效数据。 关于数据质量的说明：本数据集直接采用浮标传输的原始数据，未进行额外筛选。存在两类典型异常：一是当存在小幅风浪（有效波高最高约40厘米）时，会出现与船舶尾波记录相关的波浪周期异常尖峰（周期约14~20秒）；二是因好奇的船员或渔民将浮标抬至船上观测，偶尔会出现有效波高的显著尖峰。此外，该浮标曾于2020年8月27日被强海流冲走，并于2020年9月3日重新布设至原位置。
