The PI's request funding to build on a previous video and data recorder by developing miniature video and data recorders (mini-VDRs) that will monitor the behavior, three-dimensional movements, swimming performance, and environment of marine animals as small as 12 kg. The mini-VDR, which is 70% smaller than the current video and data recorders, will be used initially in a study of the hunting behavior and foraging strategies of free-ranging Antarctic fur seals. The new mini-VDR will consist of a single, resin encased instrument that will contain the video camera with near-infrared LEDs as a light source, fast-acquisition Global Positioning System (GPS), micro-controllers, sensors for pressure, swim speed, compass bearing, ambient temperature, light level, sound, tilt, pitch and roll, and replaceable lithium batteries. The use of on-the-fly MPEG4 video compression and a 4 gigabyte Flash memory card for storing digital video and audio will allow a considerable size reduction from previous designs while retaining full programmability.Broader ImpactsThe work that is planned will be of unusually great public interest. The animals are interesting, the research is innovative and adventurous, and the ability to follow animals in the wild as they travel to great depths and chase fish and other living creatures is bound to be fascinating. The team has an impressive record of reaching out to teachers and students. This project is a natural for extension to the public and for the potential to include students and non-professional researchers. The PI has a proven track record of making his research available to other researchers as well as producing an excellent website for layman. The proposal will deliver novel science that will also help promote teaching, training, and learning. Through proper outreach, this project will likely form an exciting example for a diverse group of individuals, not just for researchers, but also for teachers, communicators and for the general public.

PI申请资金是为了在先前的视频和数据记录仪的基础上，开发微型视频和数据记录仪（mini- vdr），用于监测小至12公斤的海洋动物的行为、三维运动、游泳表现和环境。迷你vdr比目前的视频和数据记录仪小70%，最初将用于研究自由放养的南极海豹的狩猎行为和觅食策略。新的迷你vdr将由一个树脂封装的仪器组成，该仪器将包含以近红外led作为光源的摄像机、快速采集全球定位系统（GPS）、微控制器、压力、游泳速度、指南针方位、环境温度、光照水平、声音、倾斜、俯仰和滚动传感器，以及可更换的锂电池。使用动态MPEG4视频压缩和一个4gb的闪存卡来存储数字视频和音频，将使以前的设计在保留完全可编程性的同时大大缩小尺寸。更广泛的影响计划中的工作将引起公众非同寻常的巨大兴趣。动物是有趣的，研究是创新的和冒险的，在野外跟随动物旅行到深海，追逐鱼和其他生物的能力一定是迷人的。该团队在接触教师和学生方面有着令人印象深刻的记录。这个项目很自然地延伸到公众，并有可能包括学生和非专业研究人员。PI在将他的研究成果提供给其他研究人员以及为外行人制作一个优秀的网站方面有着良好的记录。该提案将带来新的科学，也将有助于促进教学、培训和学习。通过适当的推广，这个项目可能会为不同群体的个人，不仅是研究人员，而且对教师，传播者和公众，形成一个令人兴奋的榜样。
