Question

the water conditions at 50 m were nearest the ranges of temperature and salinity indentified as an __ mass (please use the first image then teh second to find the answer)

a. NACSW

b. MIW

c. AAIW

d. AABW

Figure 5B-2 provides data collected from the CORIOLIS ARVOR profiler
#6903264 in the Atlantic Ocean. The left profile shows the change in temperature
(°C) with depth. The right profile shows the change in salinity (practical salinity
units) with depth. The data was collected on 13 November 2020. 1 decibar of water
pressure corresponds to 1 m of water depth.

The Temperature-Salinity (T-S) diagram in Figure 5B-3 shows the typical range of
temperature and salinity combinations in ocean water and the resulting density. The
T-S diagram is a simple but powerful tool used to understand water mass properties.
(Refer to Investigation 3A to review the T-S diagram and its interpretation.)
