The selection process for map projections is a mystery to many mapmakers and GIS users. Map projections ought to be selected based on the map’s geographic extent and the required distortion properties, with the goal of minimizing the distortion of...

Knowledge of the shear stress on a fault during slip is necessary
for a physically-based understanding of earthquakes. Borehole
temperature measurements inside the fault zone immediately after
an earthquake can record the energy dissipated by this...

The 2014 Working Group on California Earthquake Probabilities
(WGCEP 2014) presents time-dependent earthquake probabilities for the third Uniform
California Earthquake Rupture Forecast (UCERF3). Building on the UCERF3 time-independent
model...

We have implemented the USGS National Climate Change Viewer (NCCV), which is an easy-to-use web application that displays future projections from global climate models over the United States at the state, county and watershed scales. We...

Abundance, size and development stage data for furcilia and juvenile euphausiids and data on timing and prevalence of attached spermatophores on adult females are used to infer spawning times by four euphausiid species in Frederick Sound and lower...

The Lena River in central Siberia is one of the
major pathways translocating terrestrial organic matter (OM)
from its vast catchment area to the coastal zone of the Laptev
Sea and the Arctic Ocean. The permafrost soils of its far
south-stretching...

Coring/logging data and physical property measurements from International Ocean Discovery
Program Expedition 349 are integrated with, and correlated to, reflection seismic data to map seismic
sequence boundaries and facies of the central basin and...

Interpretation of ice core trace gas records depends on an accurate understanding of the
processes that smooth the atmospheric signal in the firn. Much work has been done to understand the
processes affecting air transport in the open pores of the...

Mitigating for increased human impact to the seafloor associated with resource extraction activities and renewable energy development can benefit from an understanding of the distribution of sensitive marine benthic species. Habitat suitability...

Captive rearing programs (hatcheries) are often used in conservation and management efforts
for at-risk salmonid fish populations. However, hatcheries typically rear juveniles in environments
that contrast starkly with natural conditions, which...

Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between...

Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through...

Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail...

Fish scales have long been used to reconstruct fine-scale habitat transitions such as the movement of juvenile fish
from freshwater, estuary, and ocean environments. Despite the importance of life history information to fisheries
management and...

AIM: Species that breed sympatrically often occupy different foraging niches to
mitigate competition for prey. When resource availability declines at the end of
the breeding season, some animals migrate to regions with more favourable...

Season affects many characteristics of populations and, as a result, the interpretations of surveys conducted at
different seasons. We explored seasonal variation in occupancy using data from four studies on the Pacific marten
Martes caurina....

Body size, mass and condition can affect an organism’s ability to cope with variation
in resource availability or metabolic demand, particularly as juveniles reach independence. It
follows that changes to parental provisioning efficiency (size and...
