A general pattern in water mass distribution and
potential shelf–basin exchange is revealed at the Laptev Sea
continental slope based on hydrochemical and stable oxygen
isotope data from the summers 2005–2009. Despite considerable
interannual...

Macromoth diversity, abundance, and community structure in the topographically complex
HJ Andrews Experimental Forest and LTER site was studied on the west slope of the Cascade Range,
Oregon. Data on 493 macromoth species (62,221 individuals) was...

Ongoing greenhouse gas emissions can modify climate processes and induce shifts in ocean temperature, pH, oxygen
concentration, and productivity, which in turn could alter biological and social systems. Here, we provide a synoptic global...

Axial Seamount, an active submarine volcano on the Juan de Fuca Ridge at 46°N, 130°W, erupted in
January 1998 along 11 km of its upper south rift zone. We use ship-based multibeam sonar, high-resolution
(1 m) bathymetry, sidescan sonar imagery,...

Vibrio vulnificus and V. parahaemolyticus in the estuarine-marine environment are of human health significance and may be
increasing in pathogenicity and abundance. Vibrio illness originating from dermal contact with Vibrio laden waters or
through...

Previous projects in the Gulf of Lion have investigated the path of terrigenous material
in the Rhone deltaic system, the continental shelf and the nearby canyon heads. This
study focuses on the slope region of the Gulf of Lion to further describe...

The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics)
program examined zooplankton populations and their predators in four coastal
marine ecosystems. Program scientists learned that environmental controls on
zooplankton vital rates, especially...

A primary focus of the US Global Ocean Ecosystem Dynamics
(GLOBEC) program was to identify the mechanisms of ecosystem response to large-scale
climate forcing under the assumption that bottom-up forcing controls a large
fraction of marine...

From the planning days preceding the establishment of the US Global
Ocean Ecosystem Dynamics (GLOBEC) program, modeling was recognized as one
of the program’s pillars. In particular, predictions of future ecosystem states in an
evolving climate...

Characterizations of tsunami hazards
along the Cascadia subduction zone hinge
on uncertainties in megathrust rupture
models used for simulating tsunami inundation.
To explore these uncertainties, we
constructed 15 megathrust earthquake scenarios...

The goal of the Pacific Ocean Boundary Ecosystem and Climate Study
(POBEX) was to diagnose the large-scale climate controls on regional transport
dynamics and lower trophic marine ecosystem variability in Pacific Ocean boundary
systems. An...

We used metatranscriptomics to study the gene transcription patterns of microbial plankton (0.2 to 64 μm) at a mesohaline station
in the Chesapeake Bay under transitions from oxic to anoxic waters in spring and from anoxic to oxic waters in...

Estimates of the relative motion between the Hawaiian and Louisville hot spots have consequences
for understanding the role and character of deep Pacific-mantle return flow. The relative motion between
these primary hot spots can be inferred by...

Plagioclase ultraphyric basalts (PUBs) have been sampled along most mid-ocean ridges with
ultraslow to intermediate spreading rates. Over the past 40 years, the prevalent models for their origin
assume positive buoyancy of plagioclase in basaltic...

We present 36 new ⁴⁰Ar-³⁹Ar incremental heating age determinations from the Caribbean Large
Igneous Province (CLIP) providing evidence for extended periods of volcanic activity and suggest a new
tectonomagmatic model for the province’s timing and...

Monthly temperature and precipitation data from 41 global climate models (GCMs)
of the Coupled Model Intercomparison Project Phase 5 (CMIP5) were compared to
observations for the 20th century, with a focus on the United States Pacific Northwest...

Deep cycle mixing in the cold tongue of the equatorial
Pacific Ocean is associated with a mean flow regime
in which the gradient Richardson number Ri (a ratio of
stratification to shear that affects the evolution of turbulence)

The way of slip transformation and strain partitioning at the eastern termination of the Kunlun
fault system remains unclear, and the question of whether this fault system is an important part for
lateral extrusion of Tibetan crust is debatable....
