Animation of the Multi-Mission Optimally Interpolated Sea Surface Salinity (OISSS) monthly level 4 global dataset based on the AQUARIUS/SAC-D, SMAP and SMOS level 2 mission data gridded on a 0.25 degree spatial grid with a monthly time scale. The dataset covers the period from September 2011 to the August 2021, and is produced at the International Pacific Research Center (IPRC) of the University of Hawaii at Manoa in collaboration with the Remote Sensing Systems (RSS), Santa Rosa, California. (https://doi.org/10.5067/SMP10-4UMCS).

This animation depicts the upper ocean turbulence by rendering the ocean temperature on a cold-warm color palette. Blue represents the colder (denser) water mostly found in the deeper and/or higher latitude oceans. Red color represents the warmer sea water found on the upper layers of the ocean. Oceanic fronts, similar to the fronts in the atmosphere that generate strong winds and weather, are formed in the upper ocean when cold and warm waters meet sideways. These fronts and their evolution are associated with strong vertical mixing and transports.

Animation of ocean surface current speed over the period January 2020 to December 2021 based on the OSCAR (Ocean Surface Current Analysis Real-time) Level 4, quarter degree grid with a 1 day resolution dataset from Earth & Space Research (ESR). Please note that the missing data are represented by the gray color. OSCAR ocean mixed layer velocities are provided at three quality levels: Final, Interim and Near Real Time with a respective latency of each of approximately 1 year, 1 month, and 2 days.

Animation of the retrieved ocean surface wind speed over the period of 1 August 2018 to 10 December 2021, produced using the CYGNSS Level 3 Science Data Record (SDR) Version 3.1 dataset, which provides wind speed data retrieved from the Delay Doppler Mapping Instrument (DDMI) aboard the CYGNSS satellite constellation. The dataset can be accessed from the PO.DAAC Portal at https://doi.org/10.5067/CYGNS-L3X31 (DOI: 10.5067/CYGNS-L3X31).

Animation of the sea surface salinity comparison from ECCO daily-averaged V4r4 and SMAP JPL 8-day running mean V5.0 datasets covering the period of 2015 to 2017. The datasets are accessible on the PO.DAAC Web Portal: https://doi.org/10.5067/ECG5D-SSH44 (DOI:10.5067/ECG5D-SSH44) and https://doi.org/10.5067/SMP50-3TPCS (DOI:10.5067/SMP50-3TPCS).

A new animation shows how global sea levels have risen more than 80 mm (3.15 inches) over the past three decades. The animation compares global sea levels measured by NASA satellites and those reconstructed using NASA's latest global ocean reanalysis from the Estimating the Circulation and Climate of the Ocean (ECCO) project. Besides showing total sea level rise, the ECCO reanalysis also shows its two main components: seawater expansion from ocean warming (stereodynamic) and increased ocean volume from melting glaciers and ice sheets (barystatic).

Along Track Sea Surface Height Anomaly data from Sentinel-6 MF are shown with rolling 10-day coverage in daily increments from December 7, 2020 to September 24, 2021. Data shown in the animation are from the “Sentinel-6 MF Jason-CS L2 P4 Altimeter Low Resolution (LR) NRT Ocean Surface Topography” product, which is accessible on the PO.DAAC Web Portal: https://doi.org/10.5067/S6AP4-2LSNR (DOI:10.5067/S6AP4-2LSNR). Note: At this time data prior to June 22, 2021 are subject to reprocessing in early 2022.
Webinar: Surfing Ocean Data in the Cloud—The Beginners' Guide to PO.DAAC in the NASA Earthdata Cloud
September 2, 2021
During this webinar, PO.DAAC team discussed which data will be hosted in the cloud, showed options for migrating ocean data discovery and access process to the cloud, and provided resources to support users in navigating this migration.
