Krill flux, acoustic methodology and penguin foraging - an integrated study.

---- Public Summary from Project ----This project is designed to provide an understanding of the interactions between krill, other zooplankton, the physical environment and the predators dependent on krill. This will directly address a number of pressing problems facing CCAMLR (the Commission for the Conservation of Antarctic Marine Living Resources) in its attempts to manage the krill fishery using an 'ecosystem approach'.Expected outcomes:As a result of logistic operations (i.e. diversion to Casey) the 29 days on site allocated to this work was reduced to 10 days. Hence only a fraction of the intended program of work was conducted.Acoustics:Acoustics data (for 38, 120, 200kHz) was collected for the top 250m of the water column for nine and a half of the planned 13 transects in our 60 x 60 nautical mile survey region.

---- 项目公开摘要 ----
本项目旨在厘清磷虾、其他浮游动物、物理环境以及依赖磷虾生存的捕食者之间的相互作用机制。这将直接解决南极海洋生物资源养护委员会（Commission for the Conservation of Antarctic Marine Living Resources，CCAMLR）在采用"生态系统方法"管理磷虾渔业过程中面临的多项紧迫问题。

预期产出：
由于后勤调度调整（即改道前往凯西站），原本分配给本项目的29天现场作业时长被缩减至10天，因此仅完成了原定工作计划的一小部分。

声学调查：
在本次60×60海里的调查区域内，原计划布设13条测线以采集水体表层250米的声学数据，最终仅完成其中9.5条测线的采集工作，所用频段涵盖38kHz、120kHz及200kHz。
