| dc.description.resumo | Hydrological data collected between 2003 and 2007 were analysed in order to describe the water masses of the Sofala Bank in Mozambique Channel, a region under the influence of outflow from the Zambezi River. The data analysis consisted in the visual inspection of temperature and salinity combined with the analysis of variance for unbalanced data. Four water masses were identified, which differ in their location, temperature, and mainly salinity. These water masses are: (i) LSSW-low salinity shelf water that occurs at the upper 15m and within 40 km from the coastline; (ii) WOSW- warmer oceanic surface waters that occurs throughout the bank at depths not exceeding 70m; (iii) DOW- deep oceanic waters that occur from the sub-surface layer to the seabed; and (iv) HSSW- high salinity shelf water that occurs offshore from 40 km at depths greater than 15m. In general, the water masses are well oxygenated with the lower limit of oxygen being 13, 7 and 5.7 mL/L for the LSSW, WOSW, and the HSSW, respectively. Fluorescence levels are low and almost homogeneous in the LSSW, but it varies with depth in the other oceanic waters. The presence of four different water masses in the Sofala Bank is likely to have ecological and management implications. | en_US |
