In previous NSF-funded studies, small video and data recorders were developed and used that can be attached to free-ranging marine mammals to observe their underwater behavior, track their three-dimensional movements and record their environment (e.g., Science 283:993-996, 1999; Science 288:133-136, 2000). This project builds upon this success by developing miniature, animal-borne oceanographic data recorders (mini-ODRs) that will record fine spatial and temporal resolution data on conductivity (salinity), temperature and dissolved oxygen as well as three-dimensional location in the water column and geolocation at the surface using marine animals as small as 12 kg. Marine mammals and other pelagic vertebrates (e.g., sea turtles, penguins large fishes) that range throughout the world's oceans and descend to depths of up to 2,000 m have the potential of carrying oceanographic instruments that record fine spatial and temporal resolution data at relatively low cost, especially in areas that are not frequently visited by research vessels (e.g., the Arctic Ocean and Southern Ocean) and during the winter when sea ice and harsh weather pose severe logistical challenges. The simultaneous measurement of conductivity (salinity), temperature and dissolved oxygen as a function of location (vertical and horizontal) in the water column is fundamental in understanding the physical and biological oceanography of a region. Such fine resolution data, when applied to large geographic areas, can provide critical information on ocean circulation and structure which influence climate and ecosystem processes over large areas. The oceans are a key element in understanding climate change, and there is an increasing need for synoptic data on a global level. Most sub-surface oceanographic data have been obtained from ship-based surveys and the deployment of drifters. Animal-borne instruments provide a relatively low cost alternative for augmenting these data, especially in polar regions.

在以前的NSF资助的研究中，开发并使用了小型视频和数据记录器，可以连接到自由放养的海洋哺乳动物，以观察它们的水下行为，跟踪它们的三维运动并记录它们的环境（例如，Science 283：993-996，1999; Science 288：133-136，2000）。该项目在这一成功的基础上，开发了微型动物携带的海洋学数据记录器，将利用小至12公斤的海洋动物记录关于电导率（盐度）、温度和溶解氧的精确时空分辨率数据以及水柱中的三维位置和水面的地理位置。 海洋哺乳动物和其他远洋脊椎动物（例如，海龟、企鹅、大型鱼类）具有以相对低的成本携带记录精细的空间和时间分辨率数据的海洋学仪器的潜力，特别是在研究船不经常访问的区域（例如，在冬季，当海冰和恶劣的天气对物流构成严峻挑战时，运输将面临巨大的挑战。同时测量电导率（盐度）、温度和溶解氧作为水柱中位置（垂直和水平）的函数，对于了解一个区域的物理和生物海洋学至关重要。这种高分辨率数据在应用于大面积地理区域时，可以提供关于影响大面积气候和生态系统进程的海洋环流和结构的重要信息。海洋是了解气候变化的一个关键因素，对全球一级的天气数据的需求日益增加。大多数次表层海洋学数据是从船基调查和部署漂流器获得的。动物携带的仪器提供了一种成本相对较低的补充这些数据的替代方法，特别是在极地地区。
