Conventional hydrogeologic framework models used to compute ocean island sustainable yields and aquifer storage neglect the complexity of nearshore offshore submarine environment. However, onshore at Hawai'i exhibits a notable volumetric discrepancy between high-elevation freshwater recharge coastal discharge. In this study, we present novel transport mechanism moving from through multilayer formation water-saturated layered basalts with interbedded low-permeability layers ash/soil. Marine...
Abstract Submarine groundwater discharge (SGD) is an important phenomenon that governs hydrological cycles at the land‐to‐ocean transition zone. SGD manifests as cold and buoyant freshwaters influx from seafloor to water column contains carbon, nutrients, metals, greenhouse gases, altering coastal areas' oceanographical biochemical properties. Here, we present electromagnetic imaging of large‐scale freshwater plumes in high‐resolution, offshore west Hawai'i. Electrical resistivity models...
Although oceanic transform faults (OTFs) are ubiquitous plate boundaries, the geological processes occurring along these systems remain underexplored. The Gofar OTF of East Pacific Rise has gained attention due to its predictable, yet enigmatic, earthquake cycle. Here, we present results from first ever controlled-source electromagnetic survey an OTF, which sampled Gofar. We find that fault is characterized by a subvertical conductor, extends into lower crust and thus implies deep fluid...
Deep sea pockmarks underlain by chimney-like or pipe structures that contain methane hydrate are abundant along the Norwegian continental margin. In such provinces interaction between formation and fluid flow has significance for benthic ecosystems possibly climate change. The Nyegga region, situated on western slope, is characterized an extensive pockmark field known to accommodate substantial gas deposits. aim of this study detect delineate both free reservoirs at one Nyegga's pockmarks....
We present high-resolution resistivity imaging of gas hydrate pipe-like structures, as derived from marine controlled-source electromagnetic (CSEM) inversions that combine towed and ocean-bottom electric field receiver data, acquired the Nyegga region, offshore Norway.2.5-D CSEM applied to data detected four new prominent vertical resistive features are likely located in proximity a major structure, known CNE03 pockmark.The model resulting inversion resolved structure high resolution,...
Seafloor massive sulphides (SMSs) are regarded as a potential future resource to satisfy the growing global demand of metals including copper, zinc and gold. Aside from mining retrieving profitable amounts seafloor, present challenge is detect delineate significant SMS accumulations, which generally located near mid-ocean ridges along submarine volcanic arc backarc spreading centres. Currently, several geophysical technologies being developed quantify occurrences that often exhibit...
SUMMARY Carbon capture and storage (CCS) within sealed geological formations is an essential strategy to reduce global greenhouse gas emissions, the primary goal of 2015 United Nations Paris Agreement. Large-scale commercial development CO2 requires high-resolution remote sensing methods monitor migration during/after injection. A formation containing a phase in its pore space commonly exhibits higher electrical resistivity than brine-saturated (background) sediments. Here, we explore added...
Abstract Tectonic plate motion and mantle dynamics processes are heavily influenced by the characteristics of lithosphere‐asthenosphere boundary (LAB), yet this remains enigmatic regarding its properties geometry. The involved in rifting at passive margins result substantial alteration lithosphere through transition from continental to oceanic lithologies. Here we employ marine magnetotelluric (MT) data acquired along a ∼135 km long profile, offshore Martha's Vineyard, New England, USA,...
The discovery of large freshwater reservoirs off Hawaii suggests that other volcanic islands may have similar resources, which could help meet water demands amid population growth and climate change.
<p>Submarine groundwater discharge (SGD) is a flow of cold and buoyant freshwater from the seafloor ocean surface. Because SGD contains carbon, nutrients, metals, green-house gases, it changes oceanographical biochemical properties coastal waters. Therefore, an important phenomenon that governs hydrological cycles at land-to-ocean transition zone. Due to high spatial distribution variability surface, nontrivial map seep location fluxes using traditional oceanographic methods....
Gas hydrates reservoirs are considered as viable energy resource to be utilised in the near future. Deep sea pockmarks underlain by pipe structures that contain abundant along Norwegian continental margin. The Nyegga region, situated on western slope, is characterized an extensive pockmark field, known accommodate substantial methane hydrate deposits. aim of this study detect and delineate both gas free accumulations at one Nyegga's pockmarks. In 2012, a marine controlled–source...
