2018 Aerial Surveys of Arctic Marine Mammals

This report describes field activities of the Aerial Surveys of Arctic Marine Mammals (ASAMM) project conducted during summer and fall (1 July–29 October) 2018, and data and analyses used to summarize field activities. Surveys were based in Utqiaġvik (formerly Barrow), Alaska, and Deadhorse, Alaska, and targeted the northeastern and southcentral Chukchi and western Beaufort seas, between 67°N and 73°N latitude, 140°W and 169°W longitude.

Long-Term Changes in Length at Maturity of Pacific Salmon in Auke Creek Alaska

Although decreasing length at maturity has been observed in some Alaska salmon populations, the generality of this trend is poorly understood. This study was undertaken to determine whether this pattern holds for multiple species of salmon from a small watershed in Southeast Alaska (Auke Creek), and if so, what abiotic and biotic factors are contributing to this phenomenon.

Forecast Fish and Marine Mammal Population Responses to Ocean Acidification in the North Pacific Ocean and Bering Sea

Approximately 30-50% of global anthropogenic CO2 emissions are absorbed by the world’s oceans (Feely et al. 2004, Sabine et al. 2004). Increased CO2 uptake by the oceans is expected to reduce surface ocean pH by 0.3 – 0.5 units over the next century, which would be the largest change in pH to occur in the last 20-200 million years (Feely et al. 2004). Ocean acidification reduces the calcium carbonate (CaCO3) saturation point. Dramatic reductions in calcium carbonate saturation have been observed in the North Pacific since the industrial revolution (Feely et al. 2004).
