The region of the ocean called the mesopelagic, of midwaters, lies in the depths between -200 and -1000 meters. It covers virtually the entire extent of the world's ocean excepting the continental shelves and small areas around ocean islands; therefore it represents one of the world's largest types of environments. The mesopelagic is characterized by cold, dark waters with ususual life forms but, in general, our knowledge of this huge region is minimal, We know of the accounts of strange fishes and the prevalence of bioluminescent organisms, but little of the distribution, abundance, and behavior of the living things that occupy these depths. Now, with the advent of some extremely sophisticated submersibles that make open water observations very sucessful, our understanding of this ocean region is starting to expand greatly. Dr. Harbison and colleagues have contributed greatly to our initial progress studying the ecology and behavior of animals in the mesopelagic world. They have proposed to conduct some preliminary investigations into the responses of mesopelagic fishes to environmental stimuli (visual and acoustic); they will also make comparisons of traditional vs. submersible sampling techniques using comparisons of traditional vs. submersible sampling techniques used in the midwaters. These studies will provide exciting new findings from this poorly known region and will yield some important information about how effective our past sampling efforts have been in this environment. The Biological Oceanography Program recommends a one-year award at $54,736.

被称为中层的海洋区域位于-200米到-1000米之间的深度。除了大陆架和海洋岛屿周围的小块地区外，它几乎覆盖了世界海洋的全部;因此，它是世界上最大的环境类型之一。中层的特点是寒冷，黑暗的沃茨与ususual生命形式，但在一般情况下，我们的知识，这一巨大的区域是最小的，我们知道的帐户奇怪的鱼类和生物发光生物的流行，但很少的分布，丰度和行为的生物占领这些深度。现在，随着一些非常复杂的潜水器的出现，使开放水域的观测非常成功，我们对这一海洋区域的了解开始大大扩展。哈比森博士和他的同事们为我们在中层世界研究动物生态和行为的初步进展做出了巨大贡献。他们提议对中层鱼类对环境刺激（视觉和听觉）的反应进行一些初步调查;他们还将利用在中层水域使用的传统取样技术与潜水取样技术的比较，对传统取样技术与潜水取样技术进行比较。这些研究将从这个鲜为人知的地区提供令人兴奋的新发现，并将产生一些重要的信息，说明我们过去的采样工作在这种环境中是多么有效。生物海洋学计划建议一年的奖金为54，736美元。
