Ecological monitoring of marine invertebrates on Isla Natividad from 2006 to 2021

This dataset encompasses information about marine invertebrates transects between 2006 to 2021 in Isla Natividad. Abundances of invertebrates can be found in the data set. Also, the dates when the transects were done, the site, the name of the diver, the depth the transect was laid, if the site was a marine reserve or not, if the site is inside a marine protected area or not, the latitude and longitude of the sites, the temperature of the water, the number of transect from where the information was counted, and the species name of each invertebrate counted. Ecological monitoring is important to collect data of species that inhabit an specific ecosystem. For this data set, we present all the data form 2006 to 2021 on algae, marine invertebrates, fish and uniform point contact at six different sites in Isla Natividad off the coast of Baja California Sur, Mexico. Data was collected once a year by trained divers as a collaborative effort from Stanford University, non-governmental organizations, and fishing cooperative federations. These data provides the abundaces of algae, invertebrates, fish and substrate of Isla Natividad over the spam of 15 years and may be use to assess changes in the ecosystems after shocks such as hypoxic events or marine heatwaves.本数据集涵盖2006年至2021年间墨西哥纳蒂维达岛（Isla Natividad）的海洋无脊椎动物（marine invertebrates）样带（transect）调查相关信息。数据集包含无脊椎动物的丰度数据，此外还涵盖样带调查的开展日期、调查点位、潜水员姓名、样带布设深度、该点位是否为海洋保护区（marine reserve）、是否位于海洋保护地（marine protected area）内、点位经纬度、水体温度、数据统计所用样带编号，以及所记录的每一种海洋无脊椎动物的物种名称。 生态监测对于获取栖息于特定生态系统的物种数据具有重要意义。本数据集收录了2006年至2021年间，墨西哥南下加利福尼亚州沿岸纳蒂维达岛6个不同点位的藻类（algae）、海洋无脊椎动物、鱼类及统一点接触法（uniform point contact）调查数据。该数据由经过培训的潜水员每年采集一次，由斯坦福大学（Stanford University）、非政府组织及渔业合作联合会联合开展。这些数据记录了纳蒂维达岛15年间藻类、无脊椎动物、鱼类及底质的丰度情况，可用于评估缺氧事件（hypoxic events）、海洋热浪（marine heatwaves）等扰动后生态系统的变化。
