Results of AIC model comparison to explain hourly maximum dive depth and dive frequency of ancient murrelets.

Notes–Wi = Akaike weight; K = number of parameters; Max dive depth = hourly maximum dive depth (m); Dive frequency = number of dives per hour; wind speed = hourly mean wind speed (km/h); wind direction (N-S)a = wind direction between North and South; wind direction (W-E) a = wind direction between West and East; wave height = hourly wave height (m); time of day a = time at daylight savings time in PST; tide change = height at next hour minus current tight; tide_difference = the highest tide minus lowest tide at a giving date acircularly transformed.
