Marine heatwaves (MHWs) are periods of anomalously warm water associated with changes in ocean structure, based on the horizontal advection masses and atmospheric exchange heat. The longest MHWs persist for many months, dramatic effects marine life have been reported from around world. As top-order predators, seabirds particularly sensitive to MHWs, high levels mortality some events, but not others. Thus, prediction impacts is straightforward, as linearly related simple measures MHW intensity, persistence, areal coverage. We describe biological responses expected seabirds, demographic parameters geographic proximity phenological timing respect seabirds. interactions between will be complex (with likely unpredictable) extend over broad spatial temporal scales. anomalous conditions breeding colonies, their overlap foraging areas, degree which coincide pre-breeding seasons presently generate greatest pressures seabird populations. posit that area-restricted species, terms movement strategies, at greater risk non-linear complicate prediction. may mediated by history strategies.

The Coats Island field station in northern Hudson Bay, Canada, was established by the Canadian Wildlife Service 1984 to monitor thick-billed murre ( Uria lomvia, akpa, [Formula: see text]) population context of harvest management and federal responsibilities under Migratory Birds Convention Act. long-term monitoring program has continued annually for 34 last 39 years, making it most frequently monitored seabird colony Arctic. In 1990s, focus efforts at site shifted from murres as an indicator environmental change. addition informing research have helped establish species Arctic seabirds, identified major shifts marine prey communities enabled assessment international agreements on reducing contaminants wildlife, improved understanding effects climate change birds. developed into essential all aspects ecology served a training new generations ecologists.
