The book "People, science and instruments of the BioSwot-Med campaign" was published at the occasion of the BioSwot2025 meeting (Marseille, France, 5-7 May 2025). It was created with the aim of giving an overview of the scientific richness of an oceanographic campaign and to preserve the memory of the passion and dedication of the participants of the BioSwot-Med project. In this book, you can learn about the people, the science, and the instruments that made the BioSwot-Med campaign in April – May 2023. In the first three sections, you can find the collection of a series of interviews carried out to cruise participants before the start of the campaign ("The research themes", "The instruments of oceanographers", "The new wave of oceanographers"). In the last section, a selection of stories and anecdotes shared by the researchers while at sea are reported ("Dispatches from sea").

Eric Guilyardi, oceanographer (CNRS, LOCEAN-IPSL) and President of the Office for Climate Education (OCE), highlighted how the SWOT project represents a major advance in the observation of the ocean and the cryosphere.

Beyond its scientific implications, the SWOT projects opens up significant opportunities for collaboration between the scientific and educational communities, providing fertile ground for climate education, ocean literacy, and the promotion of space science.

Eric Guilyardi also emphasized how data acquired by SWOT will be used to enrich the next edition of the  teacher's manual "Ocean and Cryosphere: The Climate in Our Hands" developed by OCE for primary and secondary educators. 

Published in 2019, this handbook offers teachers a ready-to-use curriculum enabling them to study the role of oceans in climate regulation, the ecosystem services provided by oceans and the cryosphere, and the effects of climate change on oceans. The activities emphasize investigative approaches and project-based learning. This teaching guide has been published in four languages and adapted for local use in Latin America, Africa, and Asia. It has been implemented by more than 10,000 teachers worldwide, reaching nearly 400,000 students.
The new version of the handbook, supported by many partners including CNES, will showcase a new section on ocean observation, highlighting space-borne observation and the contributions of the SWOT mission.

The other panelists were Djian Sadadou, Head of International Relations and Communities - Office for Climate Education, International; Narissa Bax, Marine Scientist at Pinngortitaleriffik Greenland Institute of Natural Resources, Nuuk; Ignacio Orellanos, Programs Coordinator, 1.5 Chile. The discussion of the panel focused on the issues linking the ocean, the cryosphere, and education in Latin America.

The SWOT mission is a global survey of Earth's surface water and is carried out by the Centre National d’Etudes Spatiales (CNES) and NASA, with contributions from the Canadian Space Agency (CSA) and the United Kingdom Space Agency.

Launched in December 2022, the SWOT satellite uses state-of-the-art radar interferometry technology to measure the elevation of water, and observes major lakes, rivers and wetlands while detecting ocean features with unprecedented resolution. SWOT data are providing critical information that is needed to assess water resources on land, track regional sea level changes, monitor coastal processes, and observe  fine scale ocean currents and eddies.

The SWOT Science Team has researchers from around the globe with expertise in oceanography and hydrology. This multidisciplinary group is tackling pressing issues such as availability of Earth's freshwater resources, our changing ocean and coasts,the cryosphere, and much more. Besides providing a fascinating exploration of our planet, their studies will contribute achieving societal goals of clean air and water, preparedness for extreme events, and adaptation to long-term environmental changes on continental scales.

   1. OGDR: May 5, 2025 (cycle 32, pass 221, sensing time 20250505_221058).
   2. IGDR: May 5, 2025 (first product: cycle 32, pass 223, sensing time 20250505_231228).
   3. GDR: February 24, 2025 (first product: cycle 29, pass 001, sensing time 20250224_103601).
2. Reprocessed GDR-S 2.01 observations from the start of the mission (January 16, 2023) through the end of cycle 28 (~February 23, 2025) is ongoing and scheduled to be released in late June 2025. 

The release note provides data access information from the CNES AVISO and NASA PO.DAAC portals, as well as further information about the NALT datasets transitioning from Version F to Version S.
 

To emphasize information from the release note :

1. The location of products at PODAAC has changed to data collections ending in “D”, e.g. L2_LR_SSH_D, L2_HR_PIXC_D, L2_HR_RiverSP_D, L2_HR_LakeSP_D, L2_HR_Raster_D, etc.
2. Please always use product granules with the highest product counter.
   1. This should always apply, but is especially important for products with measurements spanning the 3-5 days following May 6, 2025.
   2. During the transition to Version D, some known anomalous products with measurements spanning the 3-5 days following May 6, 2025 were generated. The affected data were reprocessed to generate nominal products with higher product counters. The anomalous products will be deleted from PODAAC and H.next by early next week. The anomalous products to be removed have a corresponding nominal product with higher product counter available.
3. The file name of each product granule contains an identifier (CRID) that enables a user to distinguish between Version C and D products.
   1. The last Version C products will be for measurements on ~May 5, 2025.
   2. The first Version D products will be for measurements on ~May 6, 2025.

Version D products will be generated for all measurements spanning the start of the calibration phase onward, and consist of:

1. Reprocessed products for observations from the start of the calibration phase (March 30, 2023) through cycle 32 (~May 19, 2025). The reprocessing of SWOT KaRIn Version D products has started and is expected to complete in early 2026.
2. Forward-processed products for measurements from May 6, 2025 onward. 

The next webinar to provide details on the major differences between Version C and D products is planned for May 19 at 15:00 UTC (08:00 PDT, 11:00 EDT, and 17:00 CET).
Please see here the link for this webinar.
(with Meeting ID: 248 509 276 543 0
Passcode: fp7ct2Rz )

The content for the May 19 webinar will be exactly the same as provided in the April 28 webinar and focus on two main topics:

1. Summarize main changes from Version C to D products
2. SWOT Reference frames, surfaces, and tides

The presentations and recordings of the April 28 webinar on each of these topics are available at:
