Inter‐annual variability in the breeding performance of seabirds in relation to oceanographic anomalies that affect the Crozet and the Kerguelen sectors of the Southern Ocean
Global warming is expected to increase the frequency and intensity of inter‐annual variation in Sea‐Surface Temperatures (SST) associated with a latitudinal shift of frontal structures in the Southern Ocean. However, the long‐term consequences of these major climatic events on the biotic environment...

Global warming is expected to increase the frequency and intensity of inter‐annual variation in Sea‐Surface Temperatures (SST) associated with a latitudinal shift of frontal structures in the Southern Ocean.

We studied the effect of SST anomalies in the southern Indian Ocean on the breeding success of eight seabird species, and found these temperature anomalies to have different effects depending on the foraging habitat of the species. The breeding success of four seabird species foraging mainly south of the Polar Front in Antarctic waters was significantly depressed by warm SST occurring mainly in winter and spring, prior to breeding.
