Deep-sea coral reef discovery (start time: 0:58) Scientists recently discovered and mapped the largest known deep-sea coral reef in the world. It’s located up to 200 miles off the U.S. Atlantic Coast, and it’s larger than Vermont. The news comes as a bright spot for oceans and marine life, when ocean acidification related to global warming, as well as overfishing, have been destroying coral reefs around the world. Contributing host Kara Fox interviews Kasey Cantwell, the operations chief for the Expeditions and Exploration Division of the National Oceanic and Atmospheric Administration, about the big discovery and its implications.

Deep-sea mining: promises and perils (start time: 10:48) Exploratory mining of the ocean floor for minerals began decades ago. Although commercialization remains elusive, some some companies are moving rapidly to exploit the seabed for commercial use. They aim to harness critical minerals – manganese, nickel, copper, cobalt and others – for use in the production of electric vehicle batteries, cell phones, wind turbines, etc. Some scientists, environmentalists, a regulatory body, and even some auto and tech companies, have called for at least a temporary ban on seabed mining, out of concern about its impact on marine life. Host Kara Fox interviews Farah Obaidullah, founder of the conservation group The Ocean and Us, and editor of a book of the same name, about seabed mining.

This week on How on Earth Beth interviews two NOAA scientists who study climate change. Joanie Kleypas is a marine ecologist who investigates how rising atmospheric carbon dioxide affects marine ecosystems. She is a self-described optimist who is committed to finding solutions to the “coral reef crisis.” Pieter Tans he has led the Carbon Cycle Greenhouse Gases group at NOAA since 1985. This group has maintained NOAA’s Global Greenhouse Gas Reference Network, producing the most widely used data of atmospheric CO2, CH4, and several other greenhouse gases and supporting measurements.
Marine Sanctuaries (starts at 5:18) This is the third feature interview In the Ocean Is Us series, which explores how we in land-locked Colorado are connected to the oceans, why they matter so much to us all, and what’s at stake. Today we discuss marine sanctuaries: the conservation science behind establishing them, and their ecological and economic benefits. In June, President Obama announced his intention to make a vast area of the
