RECOVER MAP 3.1.3.3 Coastal Gradients of Flow, Salinity, and Nutrients (http://sofia.usgs.gov/projects/coastal_grads/)

Coastal Gradients across the freshwater-marine interface of the mangrove estuaries of Florida Bay and the Southwest Florida shelf are monitored to:
- Track salinity gradients along historic flow paths that will be restored by CERP and relate to fresh water flow volumes and sea level.
- Delineate the boundaries of coastal regions for the stratified random sample design
- Measure freshwater flow volumes and nutrient inputs into the high-productivity salinity transition zone of the mangrove estuary to support the elevation of estuarine productivity in relation to freshwater inputs from CERP.
- Measure freshwater flow volumes and nutrient inputs from Greater Everglades Wetlands to Florida Bay and Gulf estuaries.

本监测针对佛罗里达湾（Florida Bay）与佛罗里达西南陆架（Southwest Florida shelf）的红树林河口（mangrove estuaries）淡水-海洋界面（freshwater-marine interface）处的海岸梯度展开，旨在达成以下目标：
- 追踪将由大沼泽地综合修复计划（Comprehensive Everglades Restoration Plan，CERP）实施修复的历史径流路径沿线的盐度梯度，并关联淡水径流量与海平面变化
- 为分层随机抽样方案划定沿海区域的边界范围
- 测定注入红树林河口高生产力盐度过渡带的淡水径流量与营养盐输入量，以支撑与CERP淡水输入相关的河口生产力提升工作
- 测定从大沼泽地湿地（Greater Everglades Wetlands）流向佛罗里达湾与海湾河口的淡水径流量与营养盐输入量
