"Nowcasts" showing areas of preferred SBT habitat based on environmental conditions in the Great Australian
Bight during the most recent week available. Age-specific habitat preferences were calculated using sea surface temperature (SST) only,
and using SST and chlorophyll a combined (see Estimating habitat preferences).
Observed conditions for nowcasts
Left: Average SST (°C) over the most recent week available.
Right: Average chlorophyll
a (mg/m
3) over available days of the corresponding week.
White indicates no data were available during that period. The dark grey, black and light grey lines indicate the 100 m, 200 m and 1000 m depth contours.

Average SST (°C) over the most recent week available in specific regions of interest.
Habitat nowcasts: SST only
Maps showing areas of preferred habitat based on SST only for age 2 fish (
left) and age 3-4 fish (
right).
Values > 1 indicate more preferred habitat, values < 1 indicate less preferred habitat.

Habitat nowcasts: SST + chlorophyll
Maps showing areas of preferred habitat based on SST and chloropyll
a combined for age 2 fish (
left) and age 3-4 fish (
right).
Values > 1 indicate more preferred habitat, values < 1 indicate less preferred habitat. White corresponds to areas where no chlorophyll data were available.
