Five Years of Sea-Surface Salinity from Space

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.

Warmer Pacific Ocean Could Release Millions of Tons of Seafloor Methane

Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these carbon deposits to melt, releasing methane into the sediments and surrounding water.

New Evidence Highlights the Carbon-regulating Capacity of the Ocean

Gland, Switzerland, Dec. 9, 2014 – Protecting key carbon-absorbing areas of the ocean and conserving fish and krill stocks are critical for tackling climate change. This is one of the findings of a report released today by the International Union for Conservation of Nature (IUCN) in which top marine scientists describe how atmospheric carbon is captured, stored and

GOCE Produces the Most Accurate Model of Ocean Current Circulation to Date

A year after the satellite reentered the atmosphere, scientists using data from the GOCE satellite have made a breakthrough in our understanding of ocean currents. The Gravity field and steady-state Ocean Circulation Explorer, or GOCE, mapped variations in Earth’s gravity with unrivalled precision, resulting in the most accurate shape of the ‘geoid’ – a hypothetical global

Better Forecasts for Sea Ice Under Climate Change

University of Adelaide-led research will help pinpoint the impact of waves on sea ice, which is vulnerable to climate change, particularly in the Arctic where it is rapidly retreating. Published today in the Proceedings of the Royal Society A, the research reports the first laboratory experiments testing theoretical models of wave activity in frozen oceans.

Underwater Robot Sheds New Light on Antarctic Sea Ice

The first detailed, high-resolution 3-D maps of Antarctic sea ice have been developed using an underwater robot. Scientists from the UK, USA and Australia say the new technology provides accurate ice thickness measurements from areas that were previously too difficult to access.

New Web Portal Displays West Coast Ocean Acidification Data

Increasing carbon dioxide in the air penetrates into the ocean and makes it more acidic, while robbing seawater of minerals that give shellfish their crunch. The West Coast is one of the first marine ecosystems to feel the effects. A new tool doesn’t alter that reality, but it does allow scientists to better understand what’s happening

BRAAVOO Designs an Unmanned Surveying Vessel and Marine Buoy to Monitor Marine Pollutants

Barcelona, Spain, Nov. 12, 2014—As a result of multiple man-made pressures, there is a slow but steady degradation of marine water quality, both chemically and biologically. The European Project BRAAVOO (Biosensors, Reporters and Algal Autonomous Vessels for Ocean Operation) was launched in December 2013 as part of the EU strategies to mitigate this problem. The

Copernicus Sentinel-1 Makes Our Seas Safer

PARIS, Oct. 23, 2014—Within the first days of its operational life, the Sentinel-1A satellite has provided data for marine services in the Arctic. During the first week of the satellite’s operational data supply, experts from the Technical University of Denmark and the Danish Meteorological Institute working under the Horizon 2020 MyOcean Follow-On project used the data
