EQW = equatorial water --low-salinity high-temperature water formed at equator;
STW = subtropical water formed as mixture between EQW and SMW;
SMW = salinity maximum water--high-salinity water formed at mid-latitudes in winter (modern analog: 18°C Water; Worthington, 1959);
SSW = shelf-sea water--high salinity water (modern analog:
MW = Mediterranean Water);
SMBW = salinity maximum bottom water. See IW identified below
HLW = high-latitude water--low-salinity water,
HLWa for temperatures greater than 5°C and no sea ice formation at 33.5 ppt,
HLWb for temperatures less than 5°C and greater than sea ice freezing point, climatic boundary near 5°C (modern analog: Antarctic Intermediate Water):
IW = transitional water--mixture of HLW and SMW (modern analog: Central Water):
HLDW = high-latitude deep water (modified from Wilde and Berry, 1982, p. 213).
