Neuse River, NC

With the help of the Institute of Marine Sciences of UNC Chapel Hill, we have begun a site study on the dynamics of the Neuse River. Recently we have collected velocity data with an ADCP, as well as temperature and pressure data. The ADCP data, however, was collected in an unusual manner. The first had the addition of recording variances (as well as means) in the ADCP. This was done in part to determine the accuracy of variance that is later computed. The second used mode 5 of the RDI WorkHorse ADCP (which collects over a smaller depth range with greater accuracy). This data was taken with the intention of understanding the limitations of mode 5, and since it was recorded in beam coordinates it is possible to compute the Reynolds stress. This relatively low energy system is ideal for such an experiment since the noise should also be quite low.
