GOLDYS hydro-biological data : Pelagic seasonal dynamics of the Gulf of Lion (North-western Mediterranean) in 2022-2023

as plankton strongly relies on environmental conditions, its abundance, composition and dynamics often reflect short term and local scale environmental variability. however, in the gulf of lion (gol, northern most part of the western mediterranean basin), plankton dynamic is still poorly understood particularly regarding its seasonal variations. in addition, major anthropogenic forcing involving heavy fishing pressure in the area have given rise to numerous management plans aimed at protecting the gol's exploited species, and led to a growing need for knowledge about the overall functioning of this complex ecosystem. a research project aimed at surveying the gol demersal and pelagic seasonal dynamics (goldys project, 2021-2023) was undertaken to attempt filling this knowledge gap (jacob, salvado et al., 2023).

浮游生物对环境条件具有高度依赖性，其丰度、组成与动态变化往往映射出短期及局部尺度的环境变异性。然而，在狮子湾（Gol，位于西地中海盆地最北端），浮游生物的动态变化仍处于理解不足的状态，尤其是其季节性变化的方面。此外，该区域因承受重大人为压力，包括过度捕捞，而引发了一系列旨在保护Gol被利用物种的管理计划，进而催生了对该复杂生态系统整体运行机制认知的需求日益增长。一项旨在调查狮子湾底栖与浮游生物季节性动态变化的研究项目（Goldys项目，2021-2023年）已启动，以期填补这一知识空白（Jacob, Salvado等，2023年）。
