西大西洋蓝鳍金枪鱼 (ABT) 从北大西洋丰富的觅食地进行长距离洄游,在墨西哥湾 (GoM) 的贫营养水域产卵。种群补充受到与 ABT 幼虫相关的物理特征的年际变化的强烈影响,但首选栖息地(反气旋环涡边缘)的营养来源和食物网结构尚不清楚。在这里,我们描述了 2017 年 5 月和 2018 年 ABT 产卵高峰期间进行的端到端过程研究的目标、物理背景、设计和主要发现。对海洋 GoM 的中尺度特征进行了幼虫调查,并进行了五次为期数天的拉格朗日实验测量了水文学和营养物质;从细菌到浮游动物和鱼类幼虫的浮游生物生物量和成分;浮游植物的养分吸收、生产力和特定分类的增长率;微型和中型浮游动物放牧;粒子输出;和 ABT 幼虫的摄食和生长率。我们对 BLOOFINZ-GoM 项目(寡营养海洋食物网中的蓝鳍金枪鱼幼虫,浮游动物的氮调查)进行了总体介绍,并强调了基于几周前实验水域回溯到其位置的发现,来自大陆坡区域的横向运输可能比涡流边缘本身更能成为幼虫利用的可用栖息地的关键决定因素。
Western Atlantic bluefin tuna (ABT) undertake long-distance migrations from rich feeding grounds in the North Atlantic to spawn in oligotrophic waters of the Gulf of Mexico (GoM). Stock recruitment is strongly affected by interannual variability in the physical features associated with ABT larvae, but the nutrient sources and food-web structure of preferred habitat, the edges of anticyclonic loop eddies, are unknown. Here, we describe the goals, physical context, design and major findings of an end-to-end process study conducted during peak ABT spawning in May 2017 and 2018. Mesoscale features in the oceanic GoM were surveyed for larvae, and five multi-day Lagrangian experiments measured hydrography and nutrients; plankton biomass and composition from bacteria to zooplankton and fish larvae; phytoplankton nutrient uptake, productivity and taxon-specific growth rates; micro- and mesozooplankton grazing; particle export; and ABT larval feeding and growth rates. We provide a general introduction to the BLOOFINZ-GoM project (Bluefin tuna Larvae in Oligotrophic Ocean Foodwebs, Investigation of Nitrogen to Zooplankton) and highlight the finding, based on backtracking of experimental waters to their positions weeks earlier, that lateral transport from the continental slope region may be more of a key determinant of available habitat utilized by larvae than eddy edges per se.
