Sentinel-3 and the ocean carbon conundrum

25 February 2016

Each year, about a quarter of the carbon dioxide we release into the atmosphere ends up in the ocean, but how it happens is still not fully understood. The Sentinel-3A satellite is poised to play an important role in shedding new light on this exchange.

SMOS meets ocean monsters

30 September 2015

ESA's SMOS and two other satellites are together providing insight into how surface winds evolve under tropical storm clouds in the Pacific Ocean. This new information could help to predict extreme weather at sea.

Surfing for science

29 July 2015

Thanks to a new system developed by scientists in the UK, taking to the waves for a spot of surfing can benefit research into the health of coastal waters, and could help confirm satellite measurements of sea-surface temperature.

SMOS on acid

17 February 2015

With fundamental changes happening to the chemistry of the world's oceans, salinity information from ESA's SMOS mission is being used with other Earth observation data to obtain information on 'the other carbon dioxide problem' - ocean acidification.

Salinity matters

18 December 2014

Measurements of salt held in surface seawater are becoming ever-more important for us to understand ocean circulation and Earth's water cycle. ESA's SMOS mission is proving essential to the quest.

Five years of soil moisture and beyond

03 November 2014

ESA's SMOS satellite has clocked up more than one billion kilometres orbiting Earth to improve our understanding of our planet's water cycle. Marking its fifth birthday, all the data collected over land and ocean have been drawn together to show how moisture in the soil and salinity in the ocean change over the year.

How does a beer cooler help understand climate?

09 July 2014

While engineers have almost finished building the first Sentinel-3 satellite for ocean forecasting and marine safety, a beer cooler has an unusual role in supporting the long-term record of sea-surface temperatures.

Pine Island retreat on the radar

27 March 2014

Twenty years of radar coverage from ESA satellites have been used to measure the rapid thinning of Antarctica's Pine Island Glacier - and it's losing more ice than previously thought.
