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 ----
本项目旨在理解磷虾、其他浮游动物、物理环境与依赖磷虾的捕食者之间的相互作用。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）在尝试采用"生态系统方法"管理磷虾渔业时面临的若干紧迫问题。

预期成果：
由于后勤操作（即转至Casey站），原分配给本项工作的29天现场时间被缩减至10天。因此，仅完成了原定工作计划的一小部分。

声学：
在我们60×60海里的调查区域内，原计划13条断面中，共对9.5条断面的水体上层250米区域采集了声学数据（频率为38、120、200kHz）。
