High-resolution ocean model looks sea turtles lost years
2021/3/26
A detailed global ocean model simulation by scientists at the National Center for Atmospheric Research and other institutions has given scientists insights into where baby sea turtles may go...
Carbon isotopes in the ocean model of the Community Earth System Model (CESM1)
ocean model Community Earth System Model
2015/8/11
Carbon isotopes in the ocean are frequently used
as paleoclimate proxies and as present-day geochemical
ocean tracers. In order to allow a more direct comparison of
climate model results with this ...
An Unstructured Grid, Finite-Volume Coastal Ocean Model (FVCOM) System
Ocean Model (FVCOM) System Unstructured Gri
2015/7/23
The coastal ocean extends from the land-sea interface where freshwater enters the ocean through rivers and estuaries to beyond the continental shelf. Due in part to its shallow and complex bathymetry ...
US GODAE:Global Ocean Prediction with the HYbrid Coordinate Ocean Model (HYCOM)
US GODAE Global Ocean Prediction HYbrid Coordinate Ocean Model
2015/7/3
During the past five to ten years, a broad partnership of institutions under NOPP sponsorship has collaborated in developing and demonstrating the performance and application of eddy-resolving, real-t...
A nonhydrostatic, isopycnal-coordinate ocean model for internal waves
Nonhydrostatic model Isopycnal coordinates Multi-layer model Internal waves Solitary waves Ocean modeling
2015/6/30
We present a nonhydrostatic ocean model with an isopycnal (density-following) vertical coordinate system. The primary motivation for the model is the proper treatment of nonhydrostatic dispersion and ...
Propagating and evanescent internal waves in a deep ocean model
Propagating evanescent internal waves deep ocean model
2012/2/28
We present experimental and computational studies of the propagation of internal waves in a stratified fluid with an exponential density profile that models the deep ocean. The buoyancy frequency prof...
Detecting unstable structures and controlling error growth by assimilation of standard and adaptive observations in a primitive equation ocean model
unstable structures error growth standard and adaptive observations primitive equation ocean model
2009/11/9
Oceanic and atmospheric prediction is based on cyclic analysis-forecast systems that assimilate new observations as they become available. In such observationally forced systems, errors amplify depend...
A comparison of the performance of 4D-Var in an explicit and implicit version of a nonlinear barotropic ocean model
4D-Var explicit and implicit version nonlinear barotropic ocean model
2009/11/3
A comparison is made of the performance of the four-dimensional variational data assimilation (4D-Var) method in an explicit and implicit version of a barotropic quasi-geostrophic model of the wind-dr...
A model of the thermally mixed layer in the upper ocean as developed by Kraus and Turner and extended by Denman is further extended to investigate the effects of salinity. In the tropical and subtropi...
Numerical Simulation Studies of Oceanic Anomalies in the North Pacific Basin. I：The Ocean Model and the Long-Term Mean State
Oceanic Anomalies North Pacific Basin Long-Term Mean State
2009/2/23
A three-dimensional, prognostic numerical model of the North Pacific Ocean, possessing an actual coastal configuration and ten layers (but constant depth), has been developed in order to show the phys...

Dynamical Forecast Experiments Barotropic Open Ocean Model
2009/2/19
The initial/boundary value problem for the barotropic version of a quasi-geostrophic open ocean model which requires normal flow everywhere on the boundary and vorticity on the inflow is studied. Para...
