The Magnuson Stevens Act (MSA) 2007 added Limited Access Privilege Programs (LAPP) in order to provide assistance to fishing communities and community-based associations in order to receive quota allocation. Community fishing associations (CFAs)...

Observed changes in climate of the U.S. Pacific Northwest since the early twentieth century were examined
using four different datasets. Annual mean temperature increased by approximately 0.6°–0.8°C from 1901 to
2012, with corroborating indicators...

By broad consensus, Open Data presents great value. However, beyond that simple statement, there are a number of complex, and sometimes contentious, issues that the science community must address. In this review, we examine the current state of...

Assessing uncertainties in hydrologic models can improve accuracy in predicting future streamflow. Here,
simulated streamflows using the Variable Infiltration Capacity (VIC) model at coarse (1/16°) and fine (1/120°)
spatial resolutions were...

An important constraint on mechanisms of past
carbon cycle variability is provided by the stable isotopic
composition of carbon in atmospheric carbon dioxide (δ¹³C-CO₂) trapped in polar ice cores, but obtaining very precise
measurements has proven...

Pacific cod (Gadus macrocephalus) is an economically and ecologically important species in the southeastern
Bering Sea and Aleutian Islands, yet little is known about the spawning dynamics of Pacific cod in
these regions. To address this knowledge...

Sea-level rise during the last deglaciation and through the Holocene was influenced by deformational,
gravitational, and rotational effects (henceforth glacial isostatic adjustment, GIA) that led to regional
departures from eustasy. Deglacial...

The Bering Sea responds rapidly to atmospheric perturbations and over the past several decades has
experienced extreme variability in both its physical and biological characteristics. These changes can
impact organisms that inhabit the region,...

In 2013, the California current was dominated by
strong coastal upwelling and high productivity. Indices
of total cumulative upwelling for particular coastal
locations reached some of the highest values on record.
Chlorophyll a levels were high...

The accuracy of state-of-the-art global barotropic tide models is assessed using bottom
pressure data, coastal tide gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and
independent tracked satellite orbit perturbations....

In field studies of solute transport, transient storage within lateral cavities and other stream features generates
breakthrough curves (BTCs) with pronounced and persistent skewness. Current solute transport
theory requires that the coefficient...

The compositions and loadings of organic matter in soils and sediments from a diverse range of environments along the Fly River system were determined to investigate carbon transport and sequestration in this region. Soil horizons from highland...

Vibrio vulnificus and Vibrio parahaemolyticus are ubiquitous in the marine–estuarine environment, but the
magnitude of human non-ingestion exposure to these waterborne pathogens is largely unknown. We evaluated
the magnitude of dermal exposure to...

We present multiple lines of evidence for years to decade-long changes in the location and
character of volcanic activity at West Mata seamount in the NE Lau basin over a 16 year period, and a hiatus
in summit eruptions from early 2011 to at least...

Clark volcano of the Kermadec arc, northeast of New Zealand, is a large stratovolcano comprised of two
coalescing volcanic cones; an apparently younger, more coherent, twin-peaked edifice to the northwest and a
relatively older, more degraded and...

The underlying causes of mortality during critical life stages of fish are not well
understood, nor is it clear if these causes are similar for naturally versus artificially propagated (i.e.
hatchery) individuals. To assess the importance of...

Pacific Lamprey Entosphenus tridentatus has declined across its range along the West Coast of North America,
and an understanding of all life history phases is needed to address population recovery. Spawning surveys (redd
counts) are common tools...

According to the “social intelligence hypothesis,” species with complex social interactions have
more sophisticated communication systems. Giant otters (Pteronura brasiliensis) live in groups
with complex social interactions. It is likely that the...

To quantify total fishing mortality it is necessary to incorporate mortality rates attributed to bycatch,
including animals that are discarded and that interact with the gear without being caught. The Reflex

The exponential growth of the salmonid farming industry during the last 3 decades has created conditions for massive escapes of these exotic species into natural environments in southern Chile. Here, we review and update information about salmonid...

Chinook Salmon Oncorhynchus tshawytscha returns to the Yukon River basin have declined dramatically since
the late 1990s, and detailed information on the spawning distribution, stock structure, and stock timing is needed to
better manage the run...

Addressing the ongoing decline of Pacific Lamprey Entosphenus tridentatus across its range along the west coast
of North America requires an understanding of all life history phases. Currently, spawning surveys (redd counts)

Concurrent measurements of predator and prey δ¹⁵N isotope values demonstrated that a cross-shelf
isotopic gradient can propagate through a marine food web from forage species to top-tier predators and
indicate foraging areas at a scale of tens of...
