The Copernicus Marine Service has released a new ocean information product. The Ocean Monitoring Indicators (OMIs) are free downloadable datasets which cover the past 25 years of key variables used in monitoring oceanic trends in line with climate change, including ocean warming, sea level rise and melting of sea ice. This free and open ocean information allows users to track the vital health signs of the ocean over the past quarter of a century.

The European Union's Copernicus Sentinel-1 mission is providing far more images than previous generations of synthetic aperture radar satellites, bringing many significant advantages. One of them is determining the difference between naturally-occurring and polluting oil on the ocean surface.
Scientists observed the bleaching of Australia's Great Barrier Reef early this year using satellite images. While capturing these events from space has been difficult in the past, Sentinel-2's frequent revisits and its resolution makes it possible.

The notion of glitter might appear as somewhat frivolous, but scientists are using Sun glitter in images from the Copernicus Sentinel-2 mission to map the motion of the sea surface.

Sea ice is a rapidly changing phenomenon. Timely measurements over large areas, at high spatial and temporal resolutions, are fundamental for its surveillance.

The international iceberg patrol service set up after the sinking of the Titanic is now able to track drifting ice from orbit more swiftly through ESA-backed cloud computing.

The EOMAP aquatic remote sensing company, together with partners at the Remote Sensing Research Centre of Queensland University and the Great Barrier Reef Foundation, are developing new methods to monitor and detect coral bleaching events using Europe's Sentinel-2A satellite.
Estonia has been awarded its first contract since becoming an ESA Member State in 2015. Over the next three years, scientists from Estonia's Tartu Observatory will head an international team to ensure that Sentinel-3's measurements of ocean colour are of the highest quality possible.

Sentinel-2A is demonstrating how it can be used to help forecast ocean waves around our coasts: sunlight reflected from the water surface reveals complex waves as they encounter the coastline and seafloor off the tip of Dorre Island, Western Australia.

Images from the Sentinel-1A satellite are being used to monitor aquaculture in the Mediterranean, in another example of the mission's contribution to food security, as fisheries become the main source of seafood.

Multiple satellites, including Europe's Sentinels, have captured images of two large icebergs that broke away from Antarctica's Nansen ice shelf on 7 April.

Following the first impressive images from Sentinel-3A, this latest Copernicus satellite is now showing us how another of its instruments, an altimeter, will track sea-level change.

How can access to Sentinel data increase Canada's ability to offer improved information on sea ice?
29 September 2015
With the new Earth observation satellites carrying a range of technologies such as radar and multispectral imaging instruments for land, ocean and atmospheric monitoring, data are available for the next 20-30 years. However, this means little unless there are capable people handling them.

ESA's fourth Space App Camp starts on Monday, with 23 professional app developers from all across Europe at the Agency's facility in Frascati, Italy.

Conservation organisations and space agencies are being called on to join forces to decide how changes in biodiversity can be monitored globally. What, exactly, should be measured by satellites?

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.
Envisat ASAR data exploitation to model oil spill, leak sources and contamination probability in the Caspian Sea
16 April 2015
The main goal of this research was to detect oil spills, to determine the oil spill frequencies and to approximate oil leak sources around the Oil Rocks Settlement, the Chilov and Pirallahi Islands in the Caspian Sea using 136 multi-temporal Envisat ASAR Wide Swath Medium Resolution images acquired during 2006-2010.

While sailing south of Africa on an around-the-world voyage, Matteo Miceli was suddenly alerted to a massive iceberg in his path. Almost 4 km long, the iceberg drifting near the Prince Edward Islands was detected and tracked by European satellites.
