Submarine gas hydrate is a hazard to drilling, potential hydrocarbon resource, and has been implicated as factor in both submarine slope stability climate change. Bulk situ electrical resistivities evaluated from electromagnetic surveys have the provide an estimate of total volume fraction more directly than by using seismic well log data. We conducted marine controlled‐source sounding at Hydrate Ridge, Oregon, USA, August, 2004. Electromagnetic fields transmitted deep‐towed horizontal...
The Coastal Data Information Program (CDIP) provides wave data to the public in near real-time, maintains an operational model for California coast, and is engaged ocean research on a global scale. CDIP's array of moored buoy stations are instrumented with Datawell Waveriders. recent work improve monitoring capabilities directional surface spectra, current, temperature described. This includes quality assurance control, real-time alerts, telemetry dissemination information technology...
Previous observations have shown that rift propagation on the Amery Ice Shelf (AIS), East Antarctica, is episodic, occurring in bursts of several hours with typical recurrence times weeks. Propagation events were deduced from seismic swarms (detected seismometers) concurrent rapid widening GPS receivers). In this study, we extend these results by deploying seismometers and receivers a dense network around tip propagating AIS over three field seasons (2002/03, 2004/05 2005/06). The pattern...
The importance of stakeholder engagement in ocean observation and particular the realization economic societal benefits is discussed, introducing a number overarching principles such as convergence on common goals, effective communication, co-production information knowledge need for innovation.

Abstract Waves overtop berms and seawalls along the shoreline of Imperial Beach (IB), CA when energetic winter swell high tide coincide. These intermittent, few-hour long events flood low-lying areas pose a growing inundation risk as sea levels rise. To support city response management, an IB warning system was developed. Total water level (TWL) forecasts combine predictions tides sea-level anomalies with wave runup estimates based on incident nonlinear model SWASH. In contrast to widely...
Similar in strength to hurricanes, Extratropical Cyclones (ECs) are responsible for innavigable sea states, coastal inundation and erosion, subsequent destruction infrastructure. Across modern operational wave models, there exists a known systematic underestimation of heights during these extreme events. Using global database EC storm tracks 36 years satellite altimeter data, we examine structure assess model performance through centered composite analyses significant height (Hs) U10 wind...
Abstract Extratropical cyclones (ECs) produce comparable wave heights and hazardous sea states to those under hurricanes. With strong wind speeds considerably larger diameters, the impact of ECs on global climate is substantial. Because occur more frequently, move quickly, exist in a large variety sizes shapes, these storms are not as well documented. Here, we present findings from EC tracking algorithm aimed at creating an database producing storms. We focus major ocean basins extratropical...
Near-surface ocean wind measurements are important for weather forecasting, determining surface transports, and estimating air-sea interactions; however, in-situ observations often limited. Previous studies indicate that the equilibrium range of gravity wave spectrum can be used to estimate velocity. This approach is tested using spectral from Coastal Data Information Program (CDIP) buoy array off Monterey, California. Quality controlled vectors inferred spectra statistically compared a...
Abstract Geophysical observations of anisotropy in oceanic lithosphere offer insight into the formation and evolution tectonic plates. Seismic is well studied but electrical remains poorly understood, especially crust uppermost mantle. Here we characterize 33 Ma Pacific using controlled‐source electromagnetic data that are highly sensitive to lithospheric azimuthal anisotropy. Our reveal ∼18–36 times more conductive paleo mid‐ocean ridge direction than perpendicular paleo‐spreading...
Landfalling tropical cyclones (TC) generate extreme waves, introducing significant property, personal, and financial risks damage. Accurate simulations of the sea state during these storms are used to support risk damage assessments design coastal structures. However, TCs a complex surface gravity wave field as result inherently strong temporal spatial gradients wind forcing. This complexity is challenge model. To advance our understanding performance models on eastern seaboard United...

Analytical and numerical solutions of the radiation pattern a single point force in general anisotropic media are known. They show that there exist remarkable differences to an excitation isotropic media, which makes it necessary consider these effects seismic modelling interpretation (Gajewski 1993). As field case patterns difficult register, has not yet been possible investigate whether peculiarities become noticeable practice or could be neglected.
