Over the last several decades, Arctic Ocean ice cover has become substantially thinner and more prone to melting, extending the period of open water. Associated with the loss of sea ice has been an increase in light penetration and a dramatic rise in the productivity of phytoplankton. The PIs? primary objectives are to determine the spatial distribution of large under-ice phytoplankton blooms on the Chukchi Shelf and the physical mechanisms that control them. The project proposed herein will utilize new data obtained from both remote instrumentation (e.g. moorings and satellites) and an interdisciplinary ship-based field program to gain a better understanding of the physical/chemical conditions that favor under-ice bloom development as well as the physiological adaptations that allow phytoplankton to flourish beneath sea ice. Outreach and education components of this project include participation in Stanford?s Summer Program for Professional Development for Science Teachers and Stanford?s School of Earth Sciences high school internship program, a compilation of professionally written short stories in the website by WHOI group, and incorporation of results by CRREL.

在过去的几十年里，北冰洋的冰盖变得越来越薄，越来越容易融化，延长了开放水域的时间。与海冰消失有关的是光穿透力的增加和浮游植物生产力的急剧上升。私家侦探？主要目标是确定楚科奇大陆架冰下浮游植物大量繁殖的空间分布以及控制它们的物理机制。本文提出的项目将利用从远程仪器（如系泊设备和卫星）和跨学科船基现场计划获得的新数据，以更好地了解有利于冰下水华发展的物理/化学条件以及使浮游植物在海冰下蓬勃发展的生理适应。该项目的推广和教育部分包括参与斯坦福大学？科学教师和斯坦福大学的暑期专业发展计划？的地球科学学院的高中实习计划，由WHOI集团在网站上汇编专业撰写的短篇小说，并由CRREL纳入结果。
