Coastal-based high-frequency (HF) radar systems are an increasingly used tool for
measuring surface currents in the coastal ocean. These systems provide a spatial and
temporal resolution not achievable with other methods. Standard-range sites...

Burial Lake sediments from the Noatak Basin in the northwest Brooks Range of Arctic Alaska (68.43°N, 159.17°W, 21.5 m water depth) provide the oldest continuous lacustrine record of paleo-environmental change and paleomagnetic secular variation...

The Bering Sea ecosystem has experienced significant climatic and biological shifts
over the past 3 decades, including temporal and spatial fluctuations of jellyfish biomass. Jellyfish
are important predators and competitors of fish; thus, it is...

The parametrized Dirac wave equation represents position and time as operators,
and can be formulated for many particles. It thus provides, unlike field–theoretic
Quantum Electrodynamics (QED), an elementary and unrestricted representation
of...

Although variations in insolation and emergent feedbacks among soil moisture,
vegetation, and soil cohesion are commonly invoked to explain topographic asymmetry that
depends on aspect, few studies have directly quantified the efficiency of...

We report thermal conductivities, thermal diffusivities, and volumetric heat capacities determined by a transient plane
heat source method for four whole-round core samples obtained by the Japan Trench Fast Drilling Project/Integrated
Ocean...

We use density and microstructure data to characterize the properties and physical setting of optical thin layers
observed over the New Jersey shelf in the summer of 2006. Layers were differentiated into two types by their
vertical position in the...

We conducted 11 independent short-term carbon dioxide (CO₂) manipulation experiments using colonies of
the filamentous cyanobacteria Trichodesmium isolated on three cruises in the North Pacific Subtropical Gyre
(NPSG). Dinitrogen (N₂) and carbon...

Recent geophysical and geological investigations of the Tibetan plateau have
given rise to conflicting models of plateau growth and deformation, where the
presence and extent of partial melt in the crust could be a determining factor. Here we...

The evolution of the near-inertial internal wavefield from ice-free summertime conditions to ice-covered
wintertime conditions is examined using data from a yearlong deployment of six moorings on the Beaufort
continental slope from August 2008 to...
