Tidal forcing and its fortnightly variation are known to be one of the main regulating agents of physical and biogeochemical signatures in the Strait of Gibraltar and surrounding areas. Samples obtained during spring and neap tides in the region were analyzed to determine the influence of this tidal variation on the submesoscale distribution of water masses and biological elements. During sprin...

In this study marine sponges of inter tidal zone from Hengam Island Persian Gulf were collected by wading at low tides in Eskeleh station at  locations 55˚ 53ʹ 40ʺ E & 26˚ 40ʹ 53ʺ N.For identifying identification of sponge samples, acid digestion method as a method of early detection and microtome section to identify the skeletal structure were used.All the identified sponges were from class De...

INTRODUCTION Little is known about the capacity and activity of emergency medical services (EMS) during large-scale disasters. This article provides a case study of the role of EMS in one large urban city during a major hurricane. METHODS The authors analyzed changes in call volume data from the City of Houston Fire Department's EMS during Hurricane Ike. Descriptive and statistical analyses a...

First, we investigated some aspects of tsunami–tide interactions based on idealized numerical experiments. Theoretically, by changing total ocean depth, tidal elevations influence the speed and magnitude of tsunami waves in shallow regions with dominating tidal signals. We tested this assumption by employing a simple 1-D model that describes propagation of tidal waves in a channel with graduall...

Marine beach water quality is typically monitored in early morning once a week without respect to tidal condition. To assess the effect of tide on this public health warning system, we analyzed enterococci (ENT) data from 60 southern California marine beaches with differing geomorphology, orientation, and proximity to runoff sources. ENT concentrations during spring tides were significantly hig...
