This dataset contains monthly-averaged ocean velocity interpolated to a regular 0.5-degree grid from the ECCO Version 4 revision 4 (V4r4) ocean and sea-ice state estimate. Estimating the Circulation and Climate of the Ocean (ECCO) ocean and sea-ice state estimates are dynamically and kinematically-consistent reconstructions of the three-dimensional, time-evolving ocean, sea-ice, and surface atmospheric states. ECCO V4r4 is a free-running solution of the 1-degree global configuration of the MIT general circulation model (MITgcm) that has been fit to observations in a least-squares sense. Observational data constraints used in V4r4 include sea surface height (SSH) from satellite altimeters [ERS-1/2, TOPEX/Poseidon, GFO, ENVISAT, Jason-1,2,3, CryoSat-2, and SARAL/AltiKa]; sea surface temperature (SST) from satellite radiometers [AVHRR], sea surface salinity (SSS) from the Aquarius satellite radiometer/scatterometer, ocean bottom pressure (OBP) from the GRACE satellite gravimeter; sea ice concentration from satellite radiometers [SSM/I and SSMIS], and in-situ ocean temperature and salinity measured with conductivity-temperature-depth (CTD) sensors and expendable bathythermographs (XBTs) from several programs [e.g., WOCE, GO-SHIP, Argo, and others] and platforms [e.g.,research vessels, gliders, moorings, ice-tethered profilers, and instrumented pinnipeds].

Surface ocean velocities estimated from HF-Radar are representative of the upper 0.3 meters of the ocean. The main objective of near-real time processing is to produce the best product from available data at the time of processing. Radial velocity measurements are obtained from individual radar sites through the U.S. HF-Radar Network. Hourly radial data are processed by unweighted least squares on a 500m resolution grid of the U.S. West Coast to produce hourly near real-time surface current maps. The subtidal current is estimated by applying a 25 hour moving average filter to the hourly surface current maps.

The Bonney Coast (BONC) HF ocean radar system covers an area of the Bonney Coast, South Australia, which has a recurring annual upwelling feature near to the coast that significantly changes the ecosystem from one of warm water originating in Western Australia, to one dominated by cold upwelling water from off the continental shelf. The dynamics of this area and the relationship between ocean circulation, chemistry and sediments control the larval species and the higher marine species and ecosystems in which they forage. The data from this site provide linking observations between the Southern Ocean and NSW through processes that occur on weekly to El Nino time scales. The BONC HF ocean radar system consists of two SeaSonde crossed loop direction finding stations located at Nora Creina (37.329 S 139.850 E) and Blackfellows Cave (37.940 S 140.457 E). These radars operate at a frequency of 5.211 MHz, with a bandwidth of 50 KHz, a maximum range of 200 Km and a range resolution of 3 Km. Within the HF radar coverage area surface currents are measured.This site was decommissioned in March 2017.

The ocean dynamic datasets of seafloor observation network experiment system at the South China Sea was completed in September 2016. This system provided energy supply and communication transmission channel through optical fiber composite power cable for the deep ocean observation platform, enabling multi-parameter, real-time and continuous ocean observation. The Subsea Dynamic Platform with CTD and ADCP was deployed in June 2017, and the collection of observation data was started from July 2017, including the collection of temperature, conductivity, water pressure from CTD and velocity from ADCP. Based on the raw observation data collected by ADCP and CTD sensors from July 2017 to December 2018, the data processing and quality control algorithm is adopted to remove outliers, add missing values, format the data and finally produce the dataset. The dataset consists of 4 data files in total: Ocean dynamic datasets of South China Sea 2017 - ADCP.CSV, totaling 1.12 MB, Ocean dynamic datasets of South China Sea 2018 - ADCP.CSV, totaling 2.24 MB, Ocean dynamic datasets of South China Sea 2017 – CTD.CSV, totaling 35.6 MB, Ocean dynamic datasets of South China Sea 2018 - CTD.CSV, totaling 73 MB.

The World Ocean Isopycnal-Level Velocity (WOIL-V) climatology was derived from the United States Navy's Generalised Digital Environmental Model (GDEM) temperature and salinity profiles, using the P-Vector Method. The absolute velocity data have the same horizontal resolution and temporal variation (annual, monthly) as GDEM (T, S) fields. These data have an horizontal resolution of 0.5 degrees ×0.5 degrees, and 222 isopycnal-levels (sigma theta levels) from sigma theta = 22.200 to 27.725 (kg m-3) with the increment delta sigma theta = 0.025 (kg m-3), however in the equatorial zone (5 degrees S – 5 degrees N) they are questionable due to the geostrophic balance being the theoretical base for the P-vector inverse method. The GDEM model, which served as the base for the calculations includes data from 1920s onwards and the WOIL-V will be updated with the same frequency as the GDEM. The climatological velocity field on isopycnal surface is dynamically compatible to the GDEM (T, S) fields and provides background ocean currents for oceanographic and climatic studies, especially in ocean isopycnal modeling. The climatology was prepared by the Department of Oceanography, Naval Postgraduate School.

The Northwest Shelf (NWA) HF ocean radar system covers an area which includes the Ningaloo Peninsula and the Ningaloo Reef to the west. The Ningaloo Reef is one of the longest and most pristine reefs in the world. The reef is rich in marine biodiversity, with shark whales, turtles and fish aggregations, and high primary and secondary productions which are controlled by the physical oceanographic processes. The NWA HF ocean radar is a WERA phased array system with 12-element receive arrays located at the Jurabi Turtle Centre (21.8068 S, 114.1015 E) and Point Billie (22.5432 S, 113.690 E). These radars operate at a frequency of 5.2625 MHz, with a bandwidth of 25 KHz and a maximum range of 200 Km. Within the HF radar coverage area surface currents are measured. Data are also collected from which wind directions and significant wave height can be calculated.
