Ocean temperatures have been extremely hot this summer, wreaking havoc on some of the world’s highly vulnerable coral reefs. With marine heat waves only expected to get worse as the climate changes, scientists are increasingly focusing on an emergency plan: collecting coral specimens and safeguarding them onshore….

6 billion tonnes of sand taken annually from oceans, causing irreparable damage to benthic life – Down to Earth

Some six billion tonnes of sand is being extracted annually from the floor of the world’s oceans, causing irreparable damage to benthic life, according to a new global data platform on sand and other sediment extraction in the marine environment.
The new data platform, Marine Sand Watch, has been developed by GRID-Geneva, a Centre for Analytics within the UN Environment Programme (UNEP). It is available at: https://unepgrid.ch/en/marinesandwatch…

The overwhelming plastic waste Hawaii visitors leave behind – SFGATE

Plastics like in-room toiletries provided by resorts, plus to-go containers and cutlery provided by restaurants, are used and discarded by guests day after day. A single hotel chain can use hundreds of millions of little bottles of shampoo and conditioner every year.

When visitors leave, a lot of these items end up in the trash, yet Hawaii doesn’t have the infrastructure to recycle the immense amount of plastic left behind…

Using ‘recycled plastic’ in construction materials may not be a great idea after all – Grist Magazine

Last month, the American Chemistry Council, a petrochemical industry trade group, sent out a newsletter highlighting a major new report on what it presented as a promising solution to the plastic pollution crisis: using “recycled” plastic in construction materials. At first blush, it might seem like a pretty good idea — shred discarded plastic into tiny pieces and you can reprocess it into everything from roads and bridges to railroad ties…

There Might Be Less Plastic in the Sea Than We Thought. But Read On – the New York Times

Plastic input into the oceans: Despite knowledge of the role played by rivers, there are no global estimates of the amount of man-made debris reaching the ocean at river mouths. Therefore, of the estimated 4.8 to 12.7 million tonnes of litter which enter the marine environment in 2010 from land-based sources within a 50 km-wide coastal zone (Jambeck et al., 2015) Illustration by Maphoto/Riccardo Pravettoni, courtesy of GRID-Arendal CC BY-NC-SA 2.0 via https://www.grida.no/resources/6906).

There’s less plastic pollution flowing into the ocean from land than scientists previously thought, according to a study published Monday in the journal Nature Geoscience.

The researchers estimated that about 500,000 metric tons of plastic end up in the ocean each year, with about half from land. The other half comes from the fishing industry in the form of nets, ropes, buoys and other equipment…

The race to defuse an oil ‘time bomb’ disaster threatening the Red Sea – Grist Magazine

Ten days ago, the crew of a ship called the Nautica lifted anchor in Djibouti and motored north in the Red Sea. Two tugboats met the vessel about five and a half miles off the coast of Yemen, then guided it into place alongside the FSO Safer, a crumbling, abandoned oil tanker thought to hold 1 million barrels of crude.

Thus began an operation that’s the ecological equivalent of placing the pin back into a hand grenade…
