项目摘要

This project is studying the physiology, toxicology, ecology and oceanography of toxic Pseudo-nitzschia (PN) species off the Pacific Northwest coast, a region in which both macro-nutrient supply and current patterns are primarily controlled by seasonal coastal upwelling processes. The long term project goal is to develop a mechanistic basis for forecasting toxic PN bloom development along the Pacific Northwest coast and in other similar coastal regions in Eastern Boundary upwelling systems. The objectives are being met with an integrated suite of field and laboratory studies on two 21 day cruises per year, moored bio/chem/physical sensors as well as circulation and biophysical modeling in a study area that includes both the eddy and also a typical coastal upwelling region. The key factors responsible for high cell densities of toxigenic PN spp. and the variable levels of cell toxicity are being investigated with on-deck incubation studies and comprehensive in situ measurements including macronutrients, micronutrients (Fe, Cu), bacteria and grazer abundance as well as photosynthetic radiation, stratification and velocity shear. Aging of blooms are being studied by following drogued patches of water both from the eddy and from a nearshore upwelling region. Toxification of coastal shellfish are being determined using beach sampling sites maintained by the Olympic Region HAB program. A coupled biophysical model of the region is being used to examine the potential for bloom generation in offshore eddy and nearshore upwelling regions (e.g., stratification, nutrient sources, strength and timing) as well as to assess transport pathways of toxic PN to the coast under a variety of environmental and physiological conditions.
该项目正在研究太平洋西北海岸有毒伪菱形藻(PN)物种的生理学、毒理学、生态学和海洋学,该地区的宏观营养物质供应和水流模式主要受季节性海岸上升流过程的控制。该项目的长期目标是为预报太平洋西北海岸和东部边界上升流系统中其他类似沿海地区的有毒赤潮发展建立一个机制基础。正在通过一套综合的实地和实验室研究来实现这些目标,这些研究包括每年两次21天的巡航、系泊的生物/化学/物理传感器以及研究区域内的环流和生物物理模型,该区域既包括涡流区域,也包括典型的沿海上升流区。产毒Pn spp细胞密度高的关键因素。不同水平的细胞毒性正在通过甲板上的培养研究和全面的现场测量进行研究,包括大量营养素、微量营养素(Fe、Cu)、细菌和食草动物的丰度以及光合作用辐射、层化和速度剪切。水华的老化正在通过跟踪来自涡流和近岸上升流区域的水滴斑块来研究。沿海贝类的毒性正在使用由奥运区HAB计划维护的海滩采样点进行确定。该区域的一个耦合生物物理模型正被用来研究在离岸涡旋和近岸上升流地区产生水华的可能性(例如,层结、营养源、强度和时间),以及评估在各种环境和生理条件下有毒Pn向海岸的运输途径。
