Question

the water conditions at 1200 m fell within the ranges of temperature and salinity identified as an ___ mass.

a. MIW

b. NACSW

c. AAIW

d. AABW

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.)

Transcribed Image Text: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.
