Measurements of chemical loadings through the Hillsboro and Boca Raton inlets (Florida, USA)

We describe a cost-effective methodology for obtaining loadings for the environmentally significant chemical species of silicate, nitrate, nitrite, ammonium, and orthophosphate through the Hillsboro and Boca Raton inlets (Florida, USA). Field measurements included 'grab' water samples obtained from each inlet during an 18-month period and four ebb tide sampling intensives conducted at both inlets. During sampling intensives, water currents were measured from a small boat using a downward-looking acoustic Doppler current profiler, and water samples were collected for analysis. Loadings were computed from the sampling intensives data and estimated for the entire period using flow estimates generated from tidal range data. These data are presented as monthly loadings from each inlet. [doi:10.7289/V51G0J8F (http://dx.doi.org/10.7289/V51G0J8F)] S. Jack Stamates, Thomas P. Carsey, Cheryl J. Brown.

本研究提出了一种低成本高效的方法，用于获取美国佛罗里达州希尔斯伯勒水道（Hillsboro Inlet）与博卡拉顿水道（Boca Raton Inlet）中具有环境重要性的化学组分——硅酸盐（silicate）、硝酸盐（nitrate）、亚硝酸盐（nitrite）、铵（ammonium）以及正磷酸盐（orthophosphate）的负载量。野外测量工作涵盖了为期18个月的两个水道的瞬时水样（grab water sample）采集，以及在两个水道开展的4次落潮密集采样作业。在密集采样作业期间，研究人员搭乘小艇使用下视式声学多普勒流速剖面仪（downward-looking acoustic Doppler current profiler）测量水流，并采集水样以供分析。研究人员基于密集采样数据计算得到负载量，并结合由潮差数据推导的流量估算值，推算出整个观测周期内的负载量。本数据集以两个水道的月度负载量形式呈现。[DOI:10.7289/V51G0J8F（http://dx.doi.org/10.7289/V51G0J8F）]
