vertical_SSS_seagrass_monitoring

These files include the acoustic data acquired from Posidonia oceanica meadows for the study entitled "Vertical configuration of a Side Scan Sonar for the monitoring of Posidonia oceanica meadows". The acoustic height of the canopy and the accumulated intensity for each surveyed site have been calculated from these data.

The acoustic data are presented as follows:

- In the case of Dénia measurements, the filenames correspond to the sites. D_1 includes only meadow part, not the bare seabed.
- In the case of Calp measurements, the filenames correspond to sites followed by the number of repetition.

- Every file contents the following:

(1) echogram -> Intensity echograma (in dB re Pa) after applying the compensation of the geometrical spreading and attenuation losses.

Columns are the pings.
Rows are the samples in time, every one equivalent to 0.0122 m.

(2) GPS -> latitude and longitude data for each ping, (EPSG:4326-WGS84).

本数据集收录了为研究“侧扫声呐在海洋植物群落监测中的垂直配置”而获取的 Posidonia oceanica 海草床声学数据。其中，对每个考察地点的冠层声学高度及累积强度已根据相关数据进行计算。

声学数据呈现方式如下：

- 对于 Denia 的测量数据，文件名对应考察地点。D_1 包含海草床部分，不包括裸露的海床。
- 对于 Calp 的测量数据，文件名对应地点后跟重复次数。

- 每个文件包含以下内容：
(1) 声呐图 -> 经几何扩散和衰减损失补偿后的强度声呐图（以分贝/帕斯卡计）。列代表脉冲，行代表时间样本，每个样本相当于 0.0122 米。
(2) GPS -> 每个脉冲的纬度和经度数据，(EPSG:4326-WGS84)。
