Figure 6: Depth occupation in relation to water column thermal structure for 2004 data from Fish A, tag 52918. (a) Thermal cross section of water column traversed by fish; each vertical bar represents a 12 hr time period, extending to the deepest point reached during the period and color-coded by temperature. Black contours define corresponding time at depth (TAD) >25%. (b) Corresponding TAD section.
