When dating marine samples with 14 C, the reservoir-age effect is usually assumed to be constant, although atmospheric 14 C production rate and ocean circulation changes cause temporal and spatial reservoir-age variations. These lead to dating errors, which can limit the interpretation of cause and effect in paleoclimate data. We used a 5 global ocean circulation model forced by transient atmos...

[1] Atmosphere model-derived flux fields are used to force coastal ocean models. Coarse resolution and incomplete boundary layer dynamics limit the accuracy of these forcing fields and hence the performance of the ocean models. We address this limitation for the west Florida shelf using optimal interpolation to blend winds measured in situ with winds produced by model analyses. By improving the...

The UVic Earth System Climate Model (version 2.8 with parameters as described in detail in (28)) includes a three-dimensional ocean general circulation model, a dynamicthermodynamic sea ice model, a simple one-layer energy-moisture balance model of the atmosphere as well as land-surface and dynamic terrestrial vegetation components at a resolution of 1.8°×3.6° with 19 vertical levels in the oce...

In order to conduct faithful simulations of ocean circulation one needs considerable computational power and storage capabilities. We study the parallelization of a three-dimensional ocean circulation model (OCM) and provide summary results from recent experiments on the Cedar hierarchical architecture. A major goal of our effort is to obtain guidelines for the proper design of OCM codes for pa...

Earth is expected to continue warming and the Red Sea is a model environment for understanding the effects of global warming on ocean microbiomes due to its unusually high temperature, salinity and solar irradiance. However, most microbial diversity analyses of the Red Sea have been limited to cultured representatives and single marker gene analyses, hence neglecting the substantial uncultured ...

Health care is adrift in a sea of change. In order to navigate challenges, such as health care reform and meaningful use, new strategies are needed. This paper examines the application of health care informatics and leveraging of the electronic health record (EHR) as a strategic tool to impact documentation accuracy and charge capture outcomes in a large academic medical center’s surgical servi...

Despite the importance of the optical properties such as the downwelling diffuse attenuation coefficient for characterizing the upper water column, until recently no in situ optical measurements were published for the Red Sea. Kirby et al. used observations from the Coastal Zone Color Scanner to characterize the spatial and temporal variability of the diffuse attenuation coefficient (Kd(490)) i...

The Indian Ocean is the least known ocean in the world with the biogeography of marine species in the West Indian Ocean (WIO) understudied. The hydrography of WIO is characterized by four distinct oceanographic systems and there were few glacial refugia formations in the WIO during the Pleistocene. We used the widely distributed intertidal barnacle Tetraclita to test the hypothesis that the dis...
