Oregon Inshore Surface Piercing Profiler Mooring

The Coastal Endurance Oregon Inshore Surface Piercing Profiler Mooring is located on the inner Continental Shelf, approximately 25 meters deep. The Continental Shelf-Slope area off the Oregon coast is a highly productive, dynamic upwelling environment. Upwelling brings nutrients to the surface sparking primary production and fueling the food web. In recent years, upwelling has also brought onto the shelf hypoxic, low oxygen, waters that can be harmful to organisms in the area. By sampling in this area, the OOI seeks to gain better insight into upwelling dynamics of this system. Like other Surface Piercing Profiler Moorings, this mooring contains a Surface Piercing Profiler that allows for the sampling of near surface phenomena as the Profiler travels through the water then breaches the surface. Fine resolution sampling of the water column, particularly at the very surface of the water, provides key insights into the exchange of gases, heat, etc. between the atmosphere and the ocean. While on the surface, the profiler transmits data to shore.

俄勒冈近岸穿水面剖面锚泊浮标（Coastal Endurance Oregon Inshore Surface Piercing Profiler Mooring）部署于近大陆架（Continental Shelf）海域，水深约25米。俄勒冈州外海的大陆架-坡地区域属于高生产力的动态上升流（upwelling）环境。上升流将营养盐输送至海面，激发海洋初级生产并支撑食物网运作。近年来，上升流还将低氧缺氧水体带至大陆架海域，对该区域的海洋生物构成危害。通过在此区域开展采样，海洋观测网（OOI）旨在更深入地解析该系统的上升流动力学机制。与其他穿水面剖面锚泊浮标系统类似，该锚泊装置搭载穿水面剖面仪（Surface Piercing Profiler），当剖面仪在水体中移动并跃出水面时，可对近表层现象开展采样。对水体柱开展高分辨率采样，尤其是在海面表层，可为解析大气与海洋之间的气体、热量等交换过程提供关键依据。当剖面仪处于海面时，会将数据传输至岸基站点。
