A pilot project to detect and forecast harmful algal blooms in the northern Gulf of Mexico

More timely access to data and information on the initiation, evolution and effects of harmful algal blooms can reduce adverse impacts on valued natural resources and human health. To achieve this in the northern Gulf of Mexico, a pilot project was initiated to develop a user-driven, end-to-end (measurements to applications) observing system. A key strategy of the project is to coordinate existing state, federal and academic programs at an unprecedented level of collaboration and partnership. Resource managers charged with protection of public health and aquatic resources require immediate notice of algal events and a forecast of when, where and what adverse effects will likely occur. Further, managers require integrated analyses and interpretations, rather than raw data, to make effective decisions. Consequently, a functional observing system must collect and transform diverse measurements into usable forecasts. Data needed to support development of forecasts will include such properties as sea surface temperature, winds, currents and waves; precipitation and freshwater flows with related discharges of sediment and nutrients; salinity, dissolved oxygen, and chlorophyll concentrations (in vivo fluorescence); and remotely-sensed spatial images of sea surface chlorophyll concentrations. These data will be provided via a mixture of discrete and autonomous in situ sensing with near real-time data telemetry, and remote sensing from space (SeaWiFS), aircraft (hyperspectral imagery) or land (high-frequency radar). With calibration across these platforms, the project will ultimately provide a 4-dimensional visualization of harmful algae events in a time frame suitable to resource managers.

区域生态系统适应性管理概念、理论框架及其应用研究

论述了生态系统适应性管理基本概念与生态系统适应循环,着重分析了生态系统恢复力范围、抗性、不稳定性与跨尺度影响。生态系统适应循环通常经历入侵、保持、破坏、调整四个阶段,前两个阶段的生态系统演替是可以预测的,而后两个阶段是复杂、难以预测的。文章提出了适应性区域生态系统管理的基本概念,并构建了其理论框架,并以三峡库区小江流域为例,对小江流域景观生态特征、区域生态胁迫进行了详细分析。在此基础上,提出要以水生生态安全为总目标,并围绕这一目标,进行流域各生态系统的恢复力辨识、生态系统适应性循环过程研究,从各系统恢复力属性特征出发,提出了具体的适应性管理方法与模式。
