Due to the fractal nature of the domain geometry in geophysical flow simulations, a completely accurate description of the domain in terms of a computational mesh is frequently deemed infeasible. Shoreline and bathymetry simplification methods are used to remove small scale details in the geometry, particularly in areas away from the region of interest. To that end, a novel method for shoreline...

The linear response function technique is used to analyze two 1300-km tracks of SEASAT altimeter data and corresponding bathymetry in the Musician Seamounts region north of Hawaii. Bathymetry and geoid height are highly correlated in the 50to 300-km wavelength range. A predictive filter is developed which can operate on SEASAT altimetry in poorly surveyed oceanic regions to indicate the presenc...

Olive et al (Reports, 16 October 2015, p. 310) argue that ~10% fluctuations in melt supply do not produce appreciable changes in ocean ridge bathymetry on time scales less than 100,000 years and thus cannot reflect sea level forcing. Spectral analysis of bathymetry in a region they highlight as being fault controlled, however, shows strong evidence for a signal from sea level variation.

[1] The fault restoration technique of De Chabalier and Avouac [1994] is applied to an ultra-highresolution bathymetry data set from the East Pacific Rise (EPR) at 18 140S. Fault offsets are calculated and subtracted from the original seafloor bathymetry to examine the morphology of the unfaulted seafloor surface within an area encompassing the ridge axis 40

N-propylsalicylidene based on silica as ion exchanger (IE) was used for the separation by complexation of Mn2+, Co2+, Ni2+, Cu2+, Hg2+, Cr3+, Fe3+, and UO22+ from their parent solutions. IE and its metal complexes are characterized by elemental analysis, electronic and infrared spectra, in addition to thermal analysis in atmospheric pressure. The mode of chelation and the proposed geometric str...

Benthic marine fossil associations have been used in paleontological studies as multivariate environmental proxies, with particular focus on their utility as water depth estimators. To test this approach directly, we evaluated modern marine invertebrate communities along an onshore-offshore gradient to determine the relationship between community composition and bathymetry, compare the performa...

Introduction Knowledge about the bathymetry of water bodies is of high economic, social, and ecologic importance. Whereas charting bathymetry for navigational purposes is indispensable for ensuring safe shipping traffic, monitoring the quantity and quality of fresh water resources gains more and more importance, especially in the light of climate change. In the European context three water rela...

The important part of the tsunami science is focused on studying the considerable influence of natural geographical objects, like islands and coast bathymetry, on the tsunami waves. Currently, such investigations are mostly implementing by physical modeling allowing obtaining good results on impacting submarine barriers on tsunami wave propagation but actually very expensive. We are designing a...

This paper reports on a study carried out for the generation of three-dimensional (3D) ocean bathymetry using airborne TOPSAR data. The main objective of this study is to utilize fuzzy arithmetic for constructing ocean bathymetry from polarized remote sensing data such as a TOPSAR image. In doing so, two three-dimensional surface models, the Volterra model and a fuzzy B-spline model which const...
