Studying sea level rise today will help us better understand its impact on tomorrow. After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL. The launch of the Sentinel-6 Michael Freilich satellite will provide new and better insights about our Earth’s changing ocean.

Our planet is changing. Our ocean is rising. And it affects us all. That’s why a new international satellite will continue the decades-long watch over our global ocean and help us better understand how climate change is reshaping our planet.

Animation of the retrieved ocean surface wind speed over the period of 1 August 2018 to 22 October 2020, produced using the CYGNSS Level 3 Science Data Record (SDR) Version 3.0 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-L3X30 (DOI: 10.5067/CYGNS-L3X30).

Evolution of the NASA Multi-Scale Ultra-High Resolution (MUR) sea surface temperature (SST) anomaly response to Tropical Cyclones Laura and Marco in 2020. It is common to observe trails of cooler water, or cold wakes, along hurricane tracks as a result of wind-induced mixing and turbulence that brings cold waters at depth to the surface. The cold wakes associated with Laura and Marco are clearly observed as waters approximately 2°C cooler from normal across the entire eastern Gulf of Mexico that persisted for several days. (MUR SST DOI: 10.5067/GHGMR-4FJ04).

The QuikSCAT satellite/instrument launched on 19 June 1999 to retrieve ocean surface wind vectors calibrated to 10 meters above the ocean surface and provides 90% global coverage over the ice-free oceans, seas and large lakes when in full operating mode. Shown in this animation is wind speed from the QuikSCAT Level 2B Version 4.1 dataset (DOI: https://doi.org/10.5067/QSX12-L2B41) from 27 October 1999 to 22 November 2009.

Animation showing the survey track and measurement data for the NASA-contracted saildrone SD1061 deployed during the ATOMIC field campaign over a 45 day period from 17 January 2020 to 2 March 2020 in the Caribbean region. Here we see time series of surface salinity and temperature measurements in relation to satellite SSS and SST respectively. The animation also maps the movement of the saildrone, with colors representing collocated satellite SSS and SST along-track. The dataset can be accessed from the PO.DAAC Portal at https://podaac.jpl.nasa.gov/dataset/SAILDRONE_ATOMIC (DOI: 10.5067/SDRON-ATOM0)
