Monthly and annual U and V vectors were summarized for 14 unique depth levels from daily means using the HYCOM and NCODA Global 1/12-degree Reanalysis. The U vector (m/s) is to the East and the V vector (m/s) is to the North. Current magnitude (m/s) was calculated using the daily U and V vectors. Descriptive statistics of mean, variance, standard deviations, minimum, and maximum were calculated for each month from the twenty years of data using the daily means (1992-2012). Mean, variance, and standard deviation was calculated for the annual summary period (1992-2012). The mean direction in degrees (with 0 = North) was calculated from the summarized U and V vector means, and represents the direction that the current is moving toward. The 1/12-degree global HYCOM+NCODA Ocean Reanalysis was funded by the U.S. Navy and the Modeling and Simulation Coordination Office. Computer time was made available by the DoD High Performance Computing Modernization Program. The output is publicly available at http://hycom.org.

Conceptual Consistency
These data are logically consistent
(1) A daily snapshot (1200 hours data file) of the HYCOM + NCODA Global 1/12ð Reanalysis data was downloaded from the HYCOM website in NetCDF format. The data range spanned from 10/2/1992 to 12/31/2012. Global temperature, salinity, u and v grids were extracted from the daily HYCOM NetCDF files for each of the available z-levels (depth).
A current magnitude grid was created for each u/v grid. Mean, minimum, maximum, variance and standard deviation grids were calculated for each variable-depth-month combination by combining all of the daily files for each variable-depth-month (e.g. temperature-40m-January). Mean, minimum, maximum, and standard deviation were also calculated by combining daily files across the entire time span (annual).
(2) Data were extracted from netCDF files and stored in CSV files for each variable, statistic, and depth level (38 depth levels)
(3) 14 unique depth levels were created as values were identical (2-125, 150-250, 300-350, 400-500, 600, 700, 800, 900-1000, 1250, 1500, 2000, 3000, 4000, 5000) and stored in a single CSV.
(4) CSVs for each statistic (mean, min, max, var, stdev) were combined into a single csv file for each month. (Therefore each variable has 12 monthly CSV and 1 annual CSV.) Note: for annual no min or max statistics were generated.
(5) All CSV files were exported as feature datasets.
(6) Direction in degrees was calculated from U and V mean vectors (not calculated for max, min, std, var). Direction is the direction the current is moving to.
(7) All CSV files were clipped by the U.S. Exclusive Economic Zone (EEZ).
(8) Any record with Null for all Depth levels was removed.
