Satellites have revolutionised our ability to measure sea level but their data becomes less reliable near coasts…To address this critical gap, ESA’s Climate Change Initiative Sea Level Project research team has reprocessed almost two decades of satellite data to establish a pioneering network of ‘virtual’ coastal stations. These stations now provide, for the first time, reliable and consistent sea-level measurements along coastlines…

Searching for radioactive waste in the depths of the Atlantic – France 24

Container (metal or concrete drums) of low-level radioactive waste, in the North-East Atlantic dumping zone (NEA zone), between 4,500 and 4,700 m deep, 1984 (courtesy of Fûts de déchets faiblement radioactifs en Altantique Nord-Est CC BY 4.0 via Wikimedia).

For nearly five decades, more than 200,000 barrels of radioactive waste were dumped in the icy depths of the northeast Atlantic. Today, no one knows precisely where these barrels are located, or what kind of state they are in. On June 15, a French-led team of scientists will set sail from Brittany in a bid to map the barrels and assess their impacts on surrounding marine ecosystems…
