We present an analysis of 2225 simulations of artificial oil well blowouts in nearshore and offshore waters of Newfoundland, Canada. In the simulations, we coupled the VDROP-J and TAMOC models to simulate the fate and transport of oil and gas from the release to the sea surface. Simulations were conducted with and without subsea dispersant injection. We analyzed the simulation database to quantify the mass fraction of oil and gas that surfaces, the mass fraction of released benzene that surfaces, and the horizontal offset to the surfacing zone. These data are also synthesized to yield empirical correlations to predict these output metrics from key input parameters. These correlations are summarized in an excel spreadsheet that allows rapid evaluation of spill dynamics with minimal initial knowledge of spill details. We call this tool an offshore response guidance table, which allows exploration of spill dynamics under diverse spill and response options.

Accurately assessing the dry deposition fluxes of inorganic nitrogen aerosol (aerosol-IN) is crucial for mitigating the ecological damage caused by excessive nitrogen in oceanic equilibria. We developed a dry deposition model to assess the dry deposition fluxes of aerosol-IN into Chinese offshore areas over a decade, with the range of 2.81 × 10-1.

Integrating ZnS:Cu@AlO/polydimethylsiloxane (PDMS) flexible matrices with optical fibers is crucial for the development of practical passive sensors. However, the fluorescence coupling efficiency is constrained by the small numerical aperture of the fiber, leading to a reduction in sensor sensitivity. To mitigate this limitation, a microsphere lens was fabricated at the end of the multimode fiber, which resulted in a 21.

Offshore windfarms (OWFs) constitute a rapidly expanding source of renewable energy that inevitably affects marine biodiversity, especially those built within critical areas for biodiversity conservation. To understand the potential effect of OWFs on bird communities, we systematically tracked bird communities and their behavior within OWFs near the Migratory Bird Sanctuaries along the Coast of the Yellow Sea in China from 2020 to 2022 using voyage investigations. The results indicated that bird diversity was greater within OWFs than in seawaters away from the OWFs.

This paper addresses the trade-off between sensitivity and sensing range in strain sensors, while introducing additional functionalities through an innovative 4D printing approach. The resulting ultraflexible sensor integrates carbon nanotubes/liquid metal hybrids and iron powders within an Ecoflex matrix. The optimization of this composition enables the creation of an uncured resin ideal for Direct Ink Writing (DIW) and a cured sensor with exceptional electromechanical, thermal, and magnetic performance.

As an important link of mercury (Hg) migration and transformation from land to ocean, rivers have been significantly influenced by anthropogenic activities, resulting in unpredictable environmental influences on the basin and offshore areas. In this study, the particulate Hg content of sediments in Xiaolangdi Reservoir (XLDR), Lijin Hydrological Station, and the Yellow River estuarine area during the water-sediment regulation scheme (WSRS) period in 2018 were analyzed, the characteristics and influencing factors of particulate Hg transport were explored. Our results revealed that the transport flux of particulate Hg into the sea during WSRS was 8.
