Figure 12
This is a graph of salinity against temperature showing 11 density anomalies as contour lines.
The horizontal axis is labelled 'salinity/ppt' and is marked from 33.5 ppt to 36.5 ppt in intervals of 0.5 ppt, with unmarked axis tick marks at intervals of 0.1 ppt.
The vertical axis is labelled 'temperature/°C' and the scale of the axis is from −2 °C to 20 °C with minor axis tick marks at intervals of 1 °C. The major axis tick marks are numbered from 0 °C to 20 °C in intervals of 5 °C.
The major and minor axes tick marks are repeated, unnumbered, along the top and right side of the graph.
Eleven density anomalies are presented with red contour lines on the graph.
Each contour line is labelled with the density ranging from 24.0 to 29.0 in intervals of 0.5. No units are indicated on the graph, but given in text as kg m−3.
The red lines show a regular diagonal banding pattern with the lines running from lower left to upper right of the graph.
The line representing the lowest density is located in the upper left of the graph and density increases toward the lower right of the graph, with an increase in the distance between each successive line as you move from top left to bottom right.
There are two points marked on the graph, labelled 'A' and 'B', and both of these points lie on the 27.5 kg m−3 density line.
Each of these points is connected to the horizontal and vertical axes by a dashed black line.
The values for each point are as follows:
Point A: salinity = 34.23 ppt, temperature = 0 °C
Point B: salinity = 36.0 ppt, temperature = 11.4 °C
