Data set: Wave transformation on a fringing reef with spurs and grooves structures.

Spurs and Grooves (SAG) are coral forereef structures with their main axis normal to the reef crest. The dimensions of SAG vary considerably at a global scale. Despite being common, there are relatively few studies that relate SAG morphology with wave transformation processes. In this contribution, measurements of wave transformation are presented from Xahualxol, Quintana Roo, Mexico (Mexican Caribbean coast), across a SAG zone with spurs height up to 7m. An array of pressure sensors and current meters sampling at high frequencies were deployed over 8 days (between November 27 and December 6, 2018). Outside the lagoon, on the forereef, six current profilers (see details in Table 1, <i>DataProcessing.docx</i>) were deployed in pairs, one on a spur and the other in the adjacent groove, at three locations: seaward array (S), central array (C) and reef array (R) at 165m, 144m and 84m, respectively, from the reef crest position. Inside the lagoon, the deployment consisted on two pressure sensors (see details in Table 1, <i>DataProcessing.docx</i>) one at the back reef (BR) and other close to coastline (B).<br>

脊槽构造（Spurs and Grooves, SAG）属于珊瑚礁前坡构造，其主轴与礁冠垂直。该类构造的尺寸在全球尺度下差异显著。尽管其分布较为普遍，但针对其形态与波浪变形过程关联机制的研究仍相对匮乏。本研究基于墨西哥金塔纳罗奥州（墨西哥加勒比海沿岸）Xahualxol海域的观测数据，报道了一处脊高可达7米的SAG分布区的波浪变形实测结果。研究团队布设了一套采用高频采样模式的压力传感器与海流计阵列，观测周期为8天（2018年11月27日至12月6日）。在潟湖外侧的礁前坡区域，共布设6台海流剖面仪（详见表1及《DataProcessing.docx》文档），采用成对布设方案：一台放置于脊上，另一台置于相邻的槽内，布设为三个阵列点位：向海阵列（S）、中部阵列（C）与礁体阵列（R），三者距礁冠位置的水平距离分别为165米、144米与84米。在潟湖内部，部署了两台压力传感器（详见表1及《DataProcessing.docx》文档）：一台设于礁后区（back reef, BR），另一台靠近岸线（B）。
