Marine and Coastal Environment

Marine and Coastal Environment overview 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 monitor sea surface temperature, and provide feedback into the the accurate estimation of oceanic carbon fluxes. The ALT Instrument supports Coastal Zone monitoring.

More on Sentinel-3's marine monitoring applications can be found in the User Guide.

Thematic Results

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Sea-level rise is one of the most threatening consequences of ongoing global warming and is a major indicator of climate change.

How do measurements from satellites flying above Earth provide essential information on the effects of climate change on our planet? Scientific and political organisations considered the question in London today.

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.

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.
