“…There is a turbid plume in the inner Deep Bay near the Shenzhen and Dasha Rivers. In this area, the TSS concentrations were greater than 20 mg/L, which is much higher than the threshold value of 10 mg/L above which primary production begins to become light limited [60,61]. The high turbidity may be partly caused by the discharge of these two rivers and, more importantly, the influence of the tide.…”

Using Deep Bay in China as an example, an effective method for the retrieval of total suspended sediment (TSS) concentration using HJ-1A/1B satellite images is proposed. The factors driving the variation of the TSS spatial distribution are also discussed. Two field surveys, conducted on August 29 and October 26, 2012, showed that there was a strong linear relationship (R 2 = 0.9623) between field-surveyed OBS (optical backscatter) measurements (5-31NTU) and laboratory-analyzed TSS concentrations (9.89-35.58 mg/L). The COST image-based atmospheric correction procedure and the pseudo-invariant features (PIF) method were combined to remove the atmospheric effects from the total radiance measurements obtained with different CCDs onboard the HJ-1A/1B satellites. Then, a simple and practical retrieval model was established based on the relationship between the satellite-corrected reflectance band ratio of band 3 and band 2 (Rrs3/Rrs2) and in-situ TSS measurements. The R 2 of the regression relationship was 0.807, and the mean relative error (MRE) was 12.78%, as determined through in-situ data validation. Finally, the influences of tide cycles, wind factors (direction and speed) and other factors on the OPEN ACCESSRemote Sens. 2014, 6 9912 variation of the TSS spatial pattern observed from HJ-1A/1B satellite images from September through November of 2008 are discussed. The results show that HJ-1A/1B satellite CCD images can be used to estimate TSS concentrations under different tides in the study area over synoptic scales without using simultaneous in-situ atmospheric parameters and spectrum data. These findings provide strong informational support for numerical simulation studies on the combined influence of tide cycles and other associated hydrologic elements in Deep Bay.

“…A salinity value below 17 can be used to trace this water mass enriched in river nutrients (e.g. Ragueneau et al 2002). The circulation exhibits pronounced seasonal variability, being cyclonic at low river discharges and strong northerly winds and anticyclonic at high river discharges and moderate northerly winds.…”
