CSWIM Coupled Small-scale Wave-Ice Model (CSWIM)
CSWIM™ is a coupled CFD-DEM system for simulating wave-ice interactions in polar marginal ice zones (MIZs). It consists of the non-hydrostatic finite-volume/finite-depth fluid dynamics model NHWAVE coupled to the discrete element particle simulator LIGGGHTS. The system is best suited to small-scale simulations, representing both waves and ice at resolutions of O(m) in domains of O(1-10 sq km).


Global HYCOM 1/12° Global HYbrid Coordinate Ocean Model (HYCOM)
Results from the 1/12° Global HYbrid Coordinate Ocean Model (HYCOM), including snapshots, animations and forecast verification statistics, mainly sea surface height (SSH), sea surface temperature (SST), surface currents and subsurface temperature and salinity. It also contains direct model-data comparisons.


GoM HYCOM Real-time 1/25° Gulf of Mexico HYCOM
Results from the 1/25° Gulf of Mexico HYbrid Coordinate Ocean Model (HYCOM), including snapshots, animations and forecast verification statistics, mainly sea surface height (SSH), sea surface temperature (SST), surface currents and subsurface temperature and salinity.


hycomARC Real-time 1/12° Arctic Cap HYCOM/CICE/NCODA Nowcast/Forecast System (ACNFS)
ACNFS is a coupled sea ice and ocean model that nowcasts and forecasts conditions in all sea ice covered areas in the northern hemisphere (poleward of 40° N). In ACNFS, Community Ice CodE (CICE) is used as the ice model and is coupled with HYbrid Coordinate Ocean Model (HYCOM). Resolution is approximately 3.5 km near the North Pole and 6.5 km near 40°N.


Real Time Ocean Environment Operational ALtimeter Processing (ALPS)
The Altimeter Products System (ALPS) is the operational Navy system that provides sea level anomaly observations of the ocean mesoscale to the Navy operational assimilation systems. The Naval Oceanographic Office (NAVOCEANO) is the Navy operational command that gathers altimeter data from available satellites, processes the data, and provides the data operationally.



SPEAR Submesoscale Prediction of Eddies by Altimeter Retrieval (SPEAR)
Advance ocean forecasts to predict eddy and front position accuracies to 10km. The ability to forecast frontal location will move forward by an order of magnitude.


Temperature versus salinity gradients below the ocean mixed layer Temperature versus salinity gradients below the ocean mixed layer
We characterize the global ocean seasonal variability of the temperature versus salinity gradients below the mixed layer using observations of conductivity temperature and depth and profiling float data from the National Ocean Data Center's World Ocean Dataset.


NRL DBDB2 NRL DBDB2 Global 2-Minute Topography
The Naval Research Laboratory Digital Bathymetry Data Base 2-minute resolution (NRL DBDB2) is a global topography data set on a 2-min by 2-min uniform grid developed for the ocean model. The NRL DBDB2 is based on the Naval Oceanographic Office (NAVO) global 5-min DBDBV/DBDB5 bathymetry and includes all the DBDBV high resolution data.


NRL SWANFAR SWANFAR™ Spectral Wave Data Assimilation System
The SWANFAR™ system is built from the spectral wave model SWAN and can assimilate frequency-directional wave spectra in arbitrary nearshore domains. The structure of the SWANFAR™ system is based on the structure of 4DVAR NCOM.
