Copernicus Marine Service releases 3rd Ocean State Report
15th October 2019
After the success of the 2nd Ocean State Report, Mercator Ocean announces the
publication of the
3rd edition of the Copernicus Marine Service Ocean State Report
(OSR3). This is an annual publication of the Copernicus Marine Service that provides
a comprehensive and state-of-the-art assessment of the current state, natural
variations, and changes in the global ocean and European regional seas. It is
meant to act as a reference document for the ocean scientific and business
communities, as well as decision-makers and the general public. Today marks the
publication of the report summary, allowing decision-makers and the general
public to have immediate information on the state of the ocean in a concise,
illustrated, and easily shareable format.
Over the past quarter of a century, the global ocean and the European seas
are warming and the sea level is rising, and a number of record-breaking
extreme events occurred in Europe and across the world.
Sea level rise in the European seas increased at a rate of 1.9 up to
4.3 millimetres per year.
Sea level rise in the Pacific Islands region increased at a rate of 2.8
to 4.8 millimetres per year.
Just like on land, the ocean suffers from heatwaves and these can have
devastating impacts on local marine ecosystems and economies. There were
Marine Heat Waves (MHWs) in multiple areas in the Mediterranean Sea during
the summer months of June, July and August, 2017.
Since 1993, there has been a sea ice extent loss of nearly 770,000 square
kilometres ( –5.89%) per decade. That is like losing sea ice
extent equivalent to well over 2 times the area of Germany every ten
Since the late 1970s until 2017, there has been a reduction of about 2
million square kilometres of sea ice extent in the Arctic; this is like
losing nearly 4 times the area of Spain over about 40 years.
Since the beginning of the Copernicus Marine record in 1993, the Antarctic
sea ice extent was actually growing; however, there was a sharp decline
starting in 2014.
From late 2014 to 2017 there was a large and rapid loss of some 2 million
square kilometres of sea ice extent in the Antarctic. This is equivalent
to a loss of nearly 4 times the area of Spain in 3 years. As a comparison,
in the Arctic, it took almost 40 years (as opposed to only 3 years in the
Antarctic) to lose the same amount of sea ice.
OSR3 explores how Copernicus Marine data and resources can contribute to
the sustainable management of fisheries and aquaculture sites.
Operational oceanographic data (such as temperature, salinity, oxygen,
etc.) is of great value for the monitoring and management of marine living
resources. However, it has historically not been used enough in the
day-to-day management of fisheries.
