Table 1. Characteristics of surface water masses.
Water mass | Salinity | Temperature |
Rio de la Plata outflow | <33 | 17–18 |
Brazil Current Waters | >34 | 16–19 |
Falklands (Malvinas) Current Water | >33.9 | - |
Shelf Water: Subantarctic | 33.78–33.9 | - |
Shelf water: High salinity | 33.58–33.78 | - |
Shelf water: Low salinity | <33.58 | - |
The temperature and salinity characteristics of water masses are based on Painter et al. [46] but where necessary modified to apply to the surface depths that relate to our study.
