Transcribed Image Text:### Oceanic Data Analysis from Argo Float --- #### Figure 5B-2 ##### Data Collection Overview: The graph in this section provides data collected from the Argo float in the Atlantic Ocean. Two critical profiles are illustrated: - **Left Profile:** Displays the change in temperature (°C) with respect to depth. - **Right Profile:** Illustrates the variation in salinity (measured in practical salinity units, psu) with depth. ##### Data Specifics: - **Collection Date:** December 8, 2018 - **Float Number:** 6901260 - **Cycle:** 44 - **Depth Measurement:** One decibar of water pressure corresponds to a 1-meter depth in water. ##### Graph Analysis: ###### Temperature Profile (Left Panel): - **X-axis (Sea temperature - degree Celsius):** Ranges from 5.0°C to 17.5°C. - **Y-axis (Sea pressure - decibar):** Goes from 0 to 2000 decibar, representing depth from the surface to 2000 meters. - The temperature profile line shows how temperature varies as the depth increases. Notice how temperature tends to decrease with increasing depth, typical of ocean thermal structures. ###### Salinity Profile (Right Panel): - **X-axis (Practical salinity - psu):** Scales from 35.25 psu to 36.25 psu. - **Y-axis (Sea pressure - decibar):** Again ranges between 0 and 2000 decibar. - The salinity profile demonstrates how salinity changes with depth. Similar to temperature, salinity in oceans usually shows distinct layering influenced by factors such as temperature and water movement. ###### Figure Caption: **Figure 5B-2.** Profiles from CORIOLIS float No. 6901260. [Coriolis Operational Oceanography] --- This data is crucial for understanding oceanographic processes, vital for marine biologists, climate scientists, and environmental analysts in their respective research and applications.
