Minimize Marine and Coastal Environment
Web Content Image

Studying the ocean's environment and the state of the coasts provides greater understanding of how these can be affected by natural processes, changing climate and human intervention.

Sentinel-3's OLCI and SLSTR instruments will monitor sea surface temperature, and provide feedback into the the accurate estimation of oceanic carbon fluxes. The ALT Instrument will support Coastal Zone monitoring.

More on Sentinel-3's marine monitoring applications can be found here.

Coastal TEP in pre-operation phase

27 July 2017

The Coastal Thematic Exploitation Platform  (C-TEP) has now entered the pre-operations phase.The existing pilot projects will be focused on exploitation of the Earth Observation data to generate and analyze indicators for aquaculture, water quality, integration of tools for information extraction from Earth Online data archives and altimetry analysis.

Sentinel-1 benefits oil seep assessment

20 July 2017

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.

Sentinel-2 captures coral bleaching of Great Barrier Reef

24 May 2017

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.

Glitter helps to monitor ocean waves

20 March 2017

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.

Looking out for coral bleaching

01 July 2016

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's first contract with ESA focuses on ocean health

07 June 2016

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.

Sun glitter reveals coastal waves

19 May 2016

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.

Sentinel-3A rides the waves

04 March 2016

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.

World’s corals under threat

24 February 2016

The current El Niño weather phenomenon is taking its toll on coral reefs, prompting a field campaign to the middle of the Pacific Ocean to explore how Europe's Sentinel-2 satellite might be able to quantify the damage on a large scale.

Shaping next-generation scientists

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.

Sentinel-2 catches eye of algal storm

04 September 2015

The Sentinel-2A satellite has been in orbit for only a matter of weeks, but new images of an algal bloom in the Baltic Sea show that it is already exceeding expectations. Built essentially as a land monitoring mission, Sentinel-2 will also certainly find its way into marine applications.

Help wanted on tracking biodiversity from space

12 August 2015

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?

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.

Reprocessed coastal altimetry data improve the quality of Significant Wave Height estimation

17 October 2014

Significant Wave Height (SWH) is mapped globally through Satellite Altimetry. SWH estimation is possible because the shape of a pulse-limited altimetric waveform depends on the sea state. The algorithm for SWH also depends on the width of the point target response (PTR) function.

Reprocessed coastal altimetry data: Design and validation of a new multi-mission methodology

07 May 2014

Coastal Satellite Altimetry data, including those from ESA's Envisat mission, have not been fully exploited yet, because the sea level estimation in coastal areas is considered unreliable.

Mapping the oceanic internal wave phase speed in the South China Sea by ERS-2 and Envisat SAR images

06 May 2014

Oceanic internal waves play an important role in nutrient distribution, primary productivity, acoustic propagation, coral reef growth, and submarine navigation. It is very difficult to measure the internal wave field because it has a complex three-dimensional structure and its motion is affected both by the structure of vertical stratification and by horizontal mean currents.
