Spectral analysis has been applied to virtually all of the world's long tide records in a search for a signal at the frequency of the Chandler wobble. In Northern Europe the amplitudes are two to ten times greater than equilibrium. Hints of a pole tide are observed at a few other stations, but at most locations the tide does not stand out above the noise continuum. A host of theoretical explana...

The effects of various Abiotic factors, including concentrations of silicate and iron, temperature, light intensity and salinity of media on two purebred red tide diatoms, Phaeodactylum tricornutum and Thalassiosira weissflogii were investigated through single and full factorial experiments. The single-factor experiments showed diatom Phaeodactylum tricornutum had the fastest growth rate with i...

In this paper the development of a single set of design parameters of the sizing of the tidally affected detention pond system was analyzed and tested. The approach uses critical duration single storm event of specified return period, together with a single harmonic tide. The design flood level is then the aggregate of the levels obtained using the system model with the four phase lags between ...

A new technology based on in situ underwater gamma-ray spectrometry of radon daughter products in water has been applied for groundwater–seawater interaction studies in the coastal regions of SE Sicily (offshore Donnalucata) and SE Brazil (offshore Ubatuba). The continuous monitoring carried out at the Donnalucata (and Ubatuba) site have revealed an inverse correlation between the Rn concentrat...

A continuous monitoring of sea level changes is important for human society since more than 50% of the world’s population live within 60 km of the coast. Sea level is traditionally observed with tide gauges that give measurements relative to the Earth’s crust. To improve the understanding of sea level changes it is necessary to perform measurements with respect to the Earth’s center of gravity....

Coastal communities are becoming increasingly more vulnerable to storm surges under a changing climate. Tide gauges can be used to monitor alongshore variations of a storm surge, but not cross-shelf features. In this study we combine Jason-2 satellite measurements with tide-gauge data to study the storm surge caused by Hurricane Igor off Newfoundland. Satellite observations reveal a storm surge...

The body temperature of ectotherms is influenced by the interaction of abiotic conditions, morphology, and behavior. Although organisms living in different thermal habitats may exhibit morphological plasticity or move from unfavorable locations, there are few examples of animals adjusting their thermal properties in response to short-term changes in local conditions. Here, we show that the inte...
