Oceanic seabirds chase tropical cyclones
In late summer and autumn, the passage of intense tropical cyclones can profoundly perturb oceanic and coastal ecosystems. Direct negative effects on individuals and marine communities can be dramatic, especially in the coastal zone,1234 but cyclones can also enhance pelagic primary and secondary pr...

In late summer and autumn, the passage of intense tropical cyclones can profoundly perturb oceanic and coastal ecosystems. Direct negative effects on individuals and marine communities can be dramatic, especially in the coastal zone,1234 but cyclones can also enhance pelagic primary and secondary production.56789 However, cyclone impacts on open ocean marine life remain poorly understood.
