Here we present a preliminary methodology and unprecedented data for sandy beach surf zones, focused on understanding the effects of the passage of storm events in surf- zooplankton communities. The main objectives of the present study were to analyze the variation of surf zone physical parameters during several storm events, which have occurred on Pehuen Co beach (PC), using high-frequency physical data and to explore the influence of these events on surf zooplankton taking into account some ecological community indicators such as taxa richness, abundance and diversity. We observed that the zooplankton community structure was significantly altered after the storms, mainly in terms of abundance, but also in the number of taxa and general diversity. In addition, important differences between storm duration were registered. The short-duration storms (< 6 h) were associated with an increase of zooplankton abundances after the events, whereas the long-duration ones (> 6 h) showed a sharp decrease in the number of organisms. Based on the present results, the coastal biological system could be completely altered during storm events, considering that the observed changes in the zooplankton community probably affect other species that interact with them, altering the trophic relationships in surf waters. Additionally, the high-frequency data provided us valuable information not only to visualize the hydrodynamic consequences of the storms, but also to explain the changes in the zooplankton community. The present contribution provides an initial step toward comprehensive research about the physical-biological interactions in surf zone waters during storms, even more in the actual context of climate change where extreme events are expected to increase in frequency and intensity.

在这里，我们介绍了沙滩冲浪区的初步方法论和前所未有的数据，重点是了解风暴事件在冲浪-浮游生物群落中的影响。本研究的主要目的是利用高频物理数据分析在Pehuen Co海滩（PC）上发生的几次风暴事件中冲浪区物理参数的变化，并探讨这些事件对冲浪浮游动物的影响。考虑到一些生态群落指标，如分类单元的丰富度，丰富度和多样性。我们观察到，暴风雨后，浮游动物的群落结构发生了显着变化，主要是在丰度方面，在分类单元的数量和总体多样性方面也是如此。另外，记录了风暴持续时间之间的重要差异。这事件发生后，短时风暴（<6小时）与浮游动物的丰度增加有关，而长时风暴（> 6 h）的生物数量急剧减少。根据目前的结果，考虑到在浮游动物群落中观察到的变化可能影响与之相互作用的其他物种，从而改变了冲浪水域的营养关系，在暴风雨期间沿海生物系统可能会发生完全改变。此外，高频数据还为我们提供了宝贵的信息，不仅可以直观地看到风暴的水动力后果，而且可以解释浮游动物群落的变化。本文稿为全面研究风暴期间冲浪带水域中的物理-生物相互作用提供了迈出的第一步，在气候变化的实际情况下，极端事件的发生频率和强度将有所增加，这是进一步的研究。
