Collaborative Research: Contrasting Under-Ice and Open-Water Phytoplankton Blooms in the Chukchi Sea

在过去的几十年里，北冰洋的冰盖变得非常薄，更容易融化，延长了开放水域的时间。与海冰消失相关的是光线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大型冰下浮游植物水华的空间分布和控制它们的物理机制。这里提议的项目将利用从远程仪器(例如系泊和卫星)和跨学科船舶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/化学条件以及允许浮游植物在海冰下繁衍的生理适应。该项目的宣传和教育部分包括参加斯坦福大学S科学教师专业发展暑期计划和斯坦福大学S地球科学学院高中实习计划，世界卫生组织在网站上汇编专业写作的短篇小说，以及将成果纳入CRREL。

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.
