NODC Standard Format Coastal Ocean Wave and Current (F181) Data from the Atlantic Remote Sensing Land/Ocean Experiment (ARSLOE) (1980) (NODC Accession 0014202)

This data set contains time series coastal ocean wave and current data collected during the Atlantic Remote Sensing Land/Ocean Experiment (ARSLOE). ARSLOE was sponsored jointly by the Coastal Engineering Research Center (CERC) of the US Army Corps of Engineers and the National Ocean Survey (now Service) of NOAA; it was conducted from 6 October to 30 November 1980 in the area off Duck, NC, near the CERC Field Research Facility. The data were collected using modern electronic sensors such as EM current meters, waveriders, wave staffs and pressure gauges.

Each series of measurements may include instrument type and characteristics, position, mean sea level, initial time, time span of the data sample and sampling period. Depending on the type of instrument used and data collected, data are reported in eight alternate data records. These contain: 1) EM current meter data (east and north components); 2) Baylor gauge data (water level); 3) pressure gauge data (water pressure); 4) waverider data (wave displacement); 5) wave direction buoy (wave displacement, east and north wave slope components); 6) wave spectra (co- and quadspectra); 7) wave data (angular Fourier coefficients); and 8) three-axis current meter data (east and north components). A text record is available for providing additional documentation.

本数据集涵盖大西洋遥感陆海实验（Atlantic Remote Sensing Land/Ocean Experiment, ARSLOE）期间采集的近岸海浪与海流时间序列数据。该实验由美国陆军工程兵团海岸工程研究中心（Coastal Engineering Research Center, CERC）与美国国家海洋和大气管理局（National Ocean Survey，现更名为国家海洋服务局）联合资助，于1980年10月6日至11月30日在北卡罗来纳州达克镇附近的CERC野外研究设施周边海域开展。数据采集采用了电磁海流计（EM current meters）、波浪浮标（waveriders）、测波杆（wave staffs）及压力传感器（pressure gauges）等现代化电子传感设备。

每组测量序列可包含仪器类型与性能参数、布设位置、平均海平面高度、初始采集时刻、数据样本时长及采样周期等元数据。根据所用仪器类型与采集数据类别的不同，数据以八种可选数据记录格式进行存储与呈现，具体包括：1）电磁海流计数据（东向与北向分量）；2）贝勒氏水位计数据（水位）；3）压力式传感器数据（水体压力）；4）波浪浮标数据（波浪位移）；5）测波方向浮标数据（波浪位移、东向与北向波浪坡度分量）；6）波浪谱数据（同相谱与正交谱）；7）波浪角域傅里叶系数数据；8）三轴海流计数据（东向与北向分量）。此外还提供配套文本记录，用于补充相关文档说明。
