Wave data of Advancing Resilience Measures for Vegetated Coastlines (ARM4VEG), Guyana

This collection contains data collected during mangrove-mudflat campaign in Guyana, during the PhD Thesis project of Uwe Best. It is being made public both to act as supplementary data for publications and the final PhD thesis document, as well as to allow for open usage by other researchers in their own work.<br><br>This dataset includes both the raw and processed data acquired by the six (6) pressure transducers (PTs) and the two (2) Acoustic Doppler Velocimeters (ADVs). Theses instruments were established along the main transect, MB at the Chateau Margot coastline, Guyana. The sampling frequency of the pressure transducers was set to 5 Hz to collect water levels and allow for the extraction of both infragravity waves, and wind-generated waves via a MATLAB script. <br>Obtained pressure data from the wave sensors were corrected for the atmospheric pressure prior to the conversion to water depths using linear wave theory. The data is pre-processed using filtering, averaging and data correction. Spectral analysis of the obtained wave signal was executed according to the Hegge and Masselink (1996) Fourier analysis scheme, resulting in wave energy density spectra for each burst.

本数据集收录了乌韦·贝斯特（Uwe Best）博士论文项目期间，在圭亚那开展的红树林潮滩科考作业中获取的观测数据。本次公开数据既可作为发表论文及最终博士学位论文的补充数据，也可供其他研究人员在其研究工作中开放使用。

本数据集包含6台压力传感器（pressure transducers, PTs）与2台声学多普勒流速仪（Acoustic Doppler Velocimeters, ADVs）采集的原始数据与预处理后数据。上述仪器沿圭亚那城堡玛戈（Chateau Margot）海岸的MB主断面布设。压力传感器的采样频率设为5 Hz，用于采集水位数据，并可通过MATLAB脚本提取亚重力波与风浪信号。通过线性波浪理论将波浪传感器获取的压力数据转换为水深前，已先对其进行大气压力校正。数据集已通过滤波、平均化与数据校正完成预处理。已依据赫格与马瑟林克（Hegge and Masselink，1996）提出的傅里叶分析方案，对获取的波浪信号进行频谱分析，得到每个采样段的波浪能量密度谱。
