Ministry hints Putin’s Arctic ambitions are not realistic. There is unease in several Russian government ministries as officials start to understand that the President’s objectives for the Northern Sea Route can not be reached. The only way to please the president might be to expand the sea route itself.
The Rio Grande Rise is an almost completely unstudied,
geologically intriguing, ecologically mysterious, potential lost continent in
the deep south Atlantic. And it also hosts dense cobalt-rich crusts.
The Rio Grande Rise is a region of deep-ocean seamounts
roughly the area of Iceland in the southwestern Atlantic. It lies west of the
Mid-Atlantic Ridge off the coast of South America and near Brazil’s island
territories. As the largest oceanic feature on the South American plate, it straddles
two microplates. And yet, like much of the southern Atlantic deep sea, it is
relatively under sampled.
Almost nothing is known about the ecology or biodiversity of
the Rio Grande Rise.
Friend of the blog and submarine legend Erika Bergman is leading an expedition to Belize’s Blue Hole! Follow along as she maps this unique ocean feature: Belize Blue Hole 2018. Some dudes are tagging along, too.
Climate change affects the natural, built, and social systems we rely on individually and through their connections to one another. These interconnected systems are increasingly vulnerable to cascading impacts that are often difficult to predict, threatening essential services within and beyond the Nation’s borders.
The following appeared this Mondayon the DSM Observer, the only trade journal committed to covering all aspects of the emerging deep-sea mining industry. Though written for the deep-sea mining community, the subject is broadly relevant to a host of ocean industries, so we reprint it below.

As a community, we discuss mining, management, and monitoring, as well as the regulations that shape them, in terms of governments, major corporations, and research institutions. The deep-sea mining community is small and the complexities of working at abyssal depths engenders collaboration, cooperation, and, in the case of exploitation, compromise. While there are many stakeholders potentially affected by deep-sea mining, only a small proportion of them will ever directly engage with the deep seafloor.
A few extremely wealthy individuals have access to private submersibles and ROVs and have on occasion made them available for research and exploration, but they are the exception. The tools necessary to reach the depths of a hydrothermal vent or polymetallic nodule field are simply too expensive.
