Understanding the CO₂cycle in the North Pacific Ocean using inverse box models
… better able to close the tracer budgets in the North Pacific than the Levitus section. The transport calculations showed that highly resolved hydrographic data are necessary to accurately determine the tracer transports, and pointed out the sensitivity of the calculation to errors in the Ekman …

A small look at the big picture: linking geopotential height anomalies to paleofloods on the Snake River, Idaho and Oregon
… of geopotential height anomalies over the North Pacific Ocean. Examination of the paleoflood record in two 4-m (12 ft) tall terraces along the Hells Canyon reach of the Snake River in Idaho and Oregon shows evidence of at least twenty-two late-Holocene extreme floods that occurred …

Subsistence whaling in Alaska
… geographic setting, the Eskimo of western and northwestern Alaska have for centuries risked the ice and elements in pursuit of one of the largest and most magnificent animals on earth, the Bowhead whale. The life cycle of the Bowhead whale wholly depends on the pack ice, near the edge of which …

Molecular systematics and biogeography of the Holarctic smelt family Osmeridae (Pisces)
… eight conflicting morphological hypotheses, the northern hemisphere smelts have long been the subjects of systematic disagreement. In addition to the uncertainty in the interrelationships within this family, the relationship of the Osmeridae to several other families remains unclear. Using DNA …

Resolving the molecular ecology of marine microbial eukaryotes with metatranscriptomes
The surface waters of the North Pacific ocean host diverse populations of microbial eukaryotes, who collectively mediate the flux of energy and matter in their environment with a significant impact on global biogeochemical cycles. The evolutionary history of these organisms spans billions of years …
