OSCAR (Ocean Surface Current Analysis Real-time) contains near-surface ocean current estimates, derived using quasi-linear and steady flow momentum equations. The horizontal velocity is directly estimated from sea surface height, surface vector wind and sea surface temperature. These data were collected from the various satellites and in situ instruments. The model formulation combines geostrophic, Ekman and Stommel shear dynamics, and a complementary term from the surface buoyancy gradient. Data are on a 1/3 degree grid with a 5 day resolution. OSCAR is generated by Earth Space Research (ESR) https://www.esr.org/research/oscar/oscar-surface-currents/. This collection contains data in 5-day files. For yearly files, see https://doi.org/10.5067/OSCAR-03D1Y

Ocean Surface Current Analyses Real-time (OSCAR) is a NASA funded research project and global surface current database. OSCAR global ocean surface mixed layer velocities are calculated from satellite-sensed sea surface height gradients, ocean vector winds, and sea surface temperature fields using geostrophy, Ekman, and thermal wind dynamics. OSCAR's continuing improvement depends on better modeling of the momentum transfer both within and across the boundaries of the turbulent mixed layer. A main research objective of the OSCAR project is to improve the generation of surface currents by ocean vector winds, and in doing so further our understanding of the mechanisms behind the transfer of momentum between the atmosphere and the ocean through the planetary boundary layer. Surface currents are provided on global grid every ~5 days, dating from 1992 to present day, with daily updates and near-real-time availability. * Principal Investigator: Kathleen Dohan (kdohan@esr.org). Co-Investigator: Gary Lagerloef (lager@esr.org). * Maximum Mask velocity is the geostrophic component at all points + any concurrent Ekman and buoyancy components. * Longitude extends from 20 E to 420 E to avoid a break in major ocean basins. Data repeats in overlap region.

Ocean Surface Current Analyses Real-time (OSCAR) is a global surface current database and NASA funded research project. OSCAR ocean mixed layer velocities are calculated from satellite-sensed sea surface height gradients, ocean vector winds, and sea surface temperature gradients using a simplified physical model for geostrophy, Ekman, and thermal wind dynamics. Daily averaged surface currents are provided on a global 0.25 x 0.25 degree grid as an average over an assumed well-mixed top 30 m of the ocean from 1993 to present day. OSCAR currents are provided at three quality levels: final, interim and nrt with a respective latency of each of approximately 1 year, 1 month, and 2 days. OSCAR is generated by Earth & Space Research (ESR) https://www.esr.org/research/oscar/. More details on the source datasets, file structure, and methodology can be found in oscarv2guide.pdf.

This project is developing a processing system and data center to provide operational ocean surface velocity fields from satellite altimeter and vector wind data. The method to derive surface currents with satellite altimeter and scatterometer data is the outcome of several years NASA sponsored research. The project will transition that capability to operational oceanographic applications. The end product is velocity maps updated daily, with a goal for eventual 2-day maximum delay from time of satellite measurement. Grid resolution is 100 km for the basin scale, and finer resolution in the vicinity of the Pacific Islands.

Office of Marine and Aviation Operations (OMAO) personnel aboard the ship submitted these data and associated metadata to NCEI. In addition, NCEI Accession 0201818 contains supplementary cruise-level metadata, which OMAO personnel logged in the Ship Daily Activity Log (SDAL). OMAO and NCEI personnel developed the automated process to archive these data under the auspices of the NOAA Rolling Deck to Repository (NOAA R2R) program.

This dataset is about: Sound velocity of Hole 23-229A.

These time-series datasets consist of Current Profiler (Teledyne ADCP and WCP, Aanderaa RCM-9) observations, and data from biophysical moorings at 6 locations in Southeast Alaska, near Cross Sound: CS1, CS2, CS3, and CS11 (ADCP and WCP locations); CS11 and CS13 (biophysical locations). Data were collected as part of the GOA IERP lower-trophic-level research effort, and include current speed and direction, calculated current components U and V, temperature, conductivity, salinity, pressure, water depth, oxygen concentration, calculated oxygen percent saturation, turbidity, raw chlorophyll fluorescence and chlorophyll a. Instrumentation included Aanderaa RCM-9 current meter, Teledyne RDI Workhorse Sentinel ADCP (WCP), Teledyne-RDI Long-Ranger 75khz ADCP (LRCP), SeaBird SBE-37 and SBE-30 profilers and WetLabs EcoFluorometers. The cruise was funded by NOAA, Pacific Marine Environmental Laboratory EcoFOCI program and the North Pacific Research Board (NPRB). Instruments were deployed in January, 2013 and recovered at the end of October, 2013 from NOAA Ship Oscar Dyson (DY1301 and DY1309, leg 2, respectively). Deployment and recovery operations on this cruise were managed by EcoFOCI personnel from NOAA/PMEL. Mooring time series data were processed at NOAA/PMEL/EcoFOCI using standard techniques. Time is recorded as UTC. Data contacts: Phyllis Stabeno, Shaun Bell, Ryan McCabe, Peggy Sullivan. Data were taken with participation from National Oceanic and Atmospheric Administration (NOAA), Pacific Marine Environmental Laboratory (PMEL), ; Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI); University of Washington, Cooperative Institute for Climate, Ocean, and Ecosystem Studies (CICOES); North Pacific Research Board (NPRB). Data are in NetCDF.

The Challenger Glider Mission is inspired by the first global scientific ocean survey conducted by the HMS Challenger from 1872-1876. The goals of the mission are to establish a collaborative international network of autonomous underwater glider ports, to assess global ocean model predictive skill while contributing real-time profile data for assimilation in ocean forecast models by operational centers worldwide, and to crowd source student-based ocean research and discovery. This glider is providing subsurface velocity, dissolved oxygen, temperature, conductivity, salinity, and density profile observations. The RU29 planned mission extends from Curacao to the Dominican Republic along 69 degrees W (the ADC2DR line). Real-time datasets will include CTD data that will be provided to the IOOS Glider DAC and GTS to support ocean and atmospheric weather forecasting.
