In the South Yellow Sea off the Jiangsu coast, there exists a special type of sand bodies, which are known as radial sand ridge field (RSRF). One of the characteristics of this area is the distinctive radial tidal current field. Although many studies have focused on the hydrodynamic environment around radial sand ridges, the knowledge on the genesis of the radial tidal current is still in a ver...

Seasonal episodes of significant tidal damping (reductions of tidal amplitudes as much as 50%) and tidal modulation were observed in the Hudson River estuary in the course of three consecutive winters from multiple tide gages. Through comparisons with United States Coast Guard ice reports, it was hypothesized that these events correspond with an increase in ice concentration and the development...

INTRODUCTION A diving rebreather currently nearing release incorporates an infra-red CO2 analyser at the end of the exhale hose and uses the expired gas CO2 measurement made at this position to detect hypercapnia. This configuration may allow exhaled anatomic and mouthpiece dead space gas to mix with alveolar gas in the exhale hose thus falsely lowering the CO2 measurement, especially at low ti...

Estuary Ecosystem, the second largest estuary in North America and home to hundreds of species of ecological, commercial, and recreational value. Unlike other estuaries in the Mid-Atlantic, the Delaware estuary’s tide range is greater than the ocean tide range, generally about 2 meters. Beaches account for 52 percent of the bay’s shore, with marsh and eroding peat accounting for most of the rem...

We study the comparative statics of the incumbency advantage in a model of electoral selection and strategic challenger entry. The incumbency advantage arises in the model because, on average, incumbents have greater ability than challengers. This is true for two reasons: high-ability candidates are more likely to win election (electoral selection) and high-quality incumbents deter challengers ...

Gravity is one of the most inexplicable forces of nature, controlling everything, from the expansion of the Universe to the ebb and flow of ocean tides. The search for the laws of motion and gravitation began more than two thousand years ago but still we do not have the complete picture of it. In this article, we have outlined how our understanding of gravity is changing drastically with time a...

Dwarf satellite galaxies undergo strong tidal forces produced by the main galaxy potential. These forces disturb the satellite, producing asymmetries in its stellar distribution, tidal tail formation, and modifications of the velocity dispersions profiles. Most of these features are observed in the Ursa Minor (UMi) dwarf spheroidal galaxy, which is one of the closest satellites of the Milky Way...

The tidal influence on LNAPL movement is a subject poorly studied with limited literature available. Tidal fluctuations along shorelines create a unique condition where the migration of LNAPLs is buffered and often mitigated from discharging into an open water body. A site investigation has been conducted in an area with presence of LNAPL located close to a major tidal river. The objective of t...

Tidal flats provide habitat for biodiversity, protection from storm surges and sea level rise, and a range of other ecosystem services. However, no simple method exists for mapping tidal flats over large (>1,000 km) extents, and consequently their global status and distribution remain poorly understood. Existing mapping methods are restricted to small areas with known tidal regimes because tida...
