Abstract In current research on deflector jet servo valves, the receiver pressure estimated using traditional two-dimensional simulation and theoretical calculation is always lower than the experimental data; therefore, ...

Traditional electromechanical cleaning equipment remains overly dependent on human assistance when performing cleaning tasks in unstructured marine environments. With the rapid development of robotic technologies, underw...

This benchmark case study introduces recently developed state-of-the-art general purpose multi-modal nonstationary reliability assessment method for marine, offshore, and naval structures, suitable for physically measure...

A novel fiber-tip micro flowmeter based on optofluidic microcavity filled with silver nanoparticles solutions (SNS) is proposed. CW fiber laser was used to heat SNS that can emit heat obviously due to the excellent optic...

Abstract The Ship Of Opportunity Expendable BathyThermograph (SOOP-XBT) Network has been measuring upper ocean temperature aboard volunteer vessels over multiple decades in key locations of the global ocean. Through inte...

The transport industry has recently shown significant interest in unmanned surface vehicles (USVs), specifically for port and inland waterway transport. These systems can improve operational efficiency and safety, which ...

Sea level rise, as one of the consequences of global climate change, has significantly impacted oceanographic dynamics, particularly wave characteristics. One of the most critical affected parameters is significant wave ...

The ongoing biodiversity disappearance on islands worldwide is alarming. Without an accurate biodiversity assessment, it is impossible to stop the loss of the world’s islands irreplaceable natural heritage. To assess b...

The Bahía Blanca Estuary is a complex system of channels and tidal flats where the most important deep water harbour system of Argentina is located. The main goal of the present work was to obtain a hydrodynamic conce...

Large-scale Euro-Atlantic variability, shaped by the polar jet stream, governs weather and climate in the Baltic Sea region, thereby impacting the physical and biogeochemical properties of the Baltic Sea ecosystem. This ...

Abstract Marine magnetic anomalies are pivotal to our understanding of plate tectonics, geomagnetic fields, and deep Earth dynamics. However, the question of how Ti‐rich titanomagnetites, the primary remanence carriers...

Coastal regions are sectors where human activities impact the marine ecosystem, and if necessary control measures are not taken, they can generate negative consequences for health and ecosystem services. Within the frame...

Tidal flats generally exhibit ponds of diverse size, shape, orientation and origin. Studying the genesis, evolution, stability and erosive mechanisms of these geographic features is critical to understand the dynamics of...

"The use of information measures for model selection in geophysical models with subgrid parameterizations is examined. Although the resolved dynamical equations of atmospheric or oceanic global numerical models are well ...

Many of Earth's most biodiverse and biogeochemically active aquatic ecosystems—including groundwater karst systems, turbid estuaries and the deep ocean—are perpetually dark and hydraulically complex, making long-term...

The productivity and linkages in the food web of the southern region of the west Antarctic Peninsula continental shelf were investigated using a multi-trophic level mass balance model. Data collected during the Southern ...

We studied the spatio-temporal variations of satellite chlorophyll-a (chl-a) and phytoplankton blooms in the continental shelf and shelf-break of the Argentinean patagonic region by means of an 11-years time series of le...

Abstract Oceanographic observations have revealed that basin‐scale Rossby waves can travel at speeds systematically exceeding values predicted by linear theory based on the flat‐bottom approximation. Using the recent...

An understanding of the mechanisms that shape animal-population dynamics is a fundamental consideration in conservation biology and ecology. Populations of the species of South-American sea lions (SASLs) Otaria flavescen...

Abstract In this study, the spatiotemporal characteristics and influencing mechanisms of eddy–eddy interactions in the Agulhas leakage region (ALR) from 1993 to 2023 are investigated. We use satellite observations and ...

Abstract Submarine fan deposits are important archives of Earth's history and serve as the record of turbidity current events that transfer large amounts of terrestrial sediment and carbon into the ocean. The geomorpholo...

The configuration of the Northern Hemisphere ice sheets during the Last and Penultimate Glacial Maxima (LGM; PGM) influenced millennial-scale climate changes, as well as solid Earth and sea level changes that occurred du...

Abstract The Paleocene–Eocene Thermal Maximum (PETM; ∼56 Ma) was a period of extreme global warming associated with a massive influx of isotopically light carbon into the ocean–atmosphere system. The burning of Pa...

Abstract The current research on gear system dynamics mainly utilizes linear spring damping model to calculate the contact force between gears. However, this linear model cannot correctly describe the energy transfer pro...
