Global Marine biodiversity data from Seawatchers Marine Citizen Science Platform 1980-2020

Observadores del Mar is a marine citizen science platform launched in 2012 devoted to enhancing the understanding of the conservation status of marine ecosystems. The platform hosts 13 projects covering 8 main taxa: corals, jellyfishes, decapod crustaceans, fishes, seaweeds, seagrasses, seabirds and molluscs, in addition to two projects focused on marine litter and reporting information on two main topics: i) biodiversity data focusing mainly on species distribution and abundance, and ii) the impacts of anthropogenic activities (e.g. jellyfish blooms) and associated mid- to long-term changes (e.g. colonization of invasive species). Almost 5500 observations validated by scientists have been already collected resulting in more than 20 scientific papers and communications. The major findings have been new records of introduced and invasive species, tracking the spread of novel pen shell mortality outbreak in the Mediterranean Sea and monitoring microplastic concentration on beaches.

海洋观察者（Observadores del Mar）是一个于2012年推出的海洋公民科学平台，致力于深化对海洋生态系统保护状况的理解。该平台汇聚了涵盖8个主要类群——珊瑚、水母、甲壳类、鱼类、海藻、海草、海鸟和软体动物——的13个项目，此外，还设有两个专注于海洋垃圾的项目，并就两大主题进行信息报告：一是聚焦于物种分布和丰度的生物多样性数据，二是人类活动（例如水母爆发）及其相关的中至长期变化（例如入侵物种的殖民化）的影响。截至目前，已有近5500条由科学家验证的观测数据被收集，并已产出超过20篇科学论文和交流报告。主要发现包括引入和入侵物种的新记录、追踪地中海新型扇贝死亡疫情的扩散以及监测海滩上的微塑料浓度。
