The principal objective of this work has been to develop a set of mechanical, remote-sensing tools that will permit the determination of the main geotechnical variables that control mine burial in the bottom. These variables include the shear strength of both soft, fine-grained sediments and coarser, dilative granular sediments. A further objective is to better understand the response of typica...

The applications of information technology as a continuous process of monitoring the various ocean parameters such as salinity, temperature, the number of waves, the movement of fish, soil and turbidity. However, there is a sporadic attempt in assessing the wave heights which is one of the important parameters to project the roughness of the sea and the smoothness of the sea bed. Once a boat ma...

With the increase in sea surface temperature (SST), scleractinian corals are exposed to bleaching threats but may possess certain flexibilities in terms of their associations with symbiotic algae. Previous studies have shown a close symbiosis between coral the and Symbiodinium; however, the spatial variation of the symbiosis and the attribution underlying are not well understood. In the present...

This work is concerned with the scattering of a train of progressive waves by a small undulation of the bottom of a laterally unbounded sea, using two-dimensional linear water wave theory. Assuming irrotational motion, a simplified perturbation analysis is employed to obtain the first-order corrections to the velocity potential by using the Green’s integral theorem in a suitable manner, and the...

This study examines the approach patterns of sharks in the vicinity of human divers, focusing on the diver’s body orientation and a shark’s distance from the sea bed when approaching the diver. A standardized video method was used to record the scenario of diver(s) kneeling in the sand while being approached by sharks. This showed that sharks had a preference to move in from outside a diver’s f...

refraction and diffraction combination of waves, is very important and applicable problem in coastal engineering (e.g. for designing break - water). however, formulation of this phenomen and numerical solution is very difficult. in this study, a numerical algorithm based on the mild slop sea bed theory is presented to obtain the appropriate governing equations of combined refraction diffraction...

35 36 New high resolution multibeam data in the Gulf of Bothnia reveal for the first time the 37 subglacial environment of a Bothnian Sea Ice Stream. The geomorphological record suggests 38 that increased meltwater production may have been important in driving rapid retreat of 39 Bothnian Sea ice during deglaciation. Here we apply a well-established one-dimensional 40 flowline model to simulate...

This study presents nearly continuous air-sea CO2 flux for 7 years using the eddy covariance method for nearshore water near San Diego, California, as well as identifying environmental processes that appear to control temporal variations in air-sea CO2 flux at different time scales using time series decomposition. Monthly variations in CO2 uptake are shown to be positively influenced by photosy...
