Droegemeier and Neumayr: Why Trump’s making ocean exploration a top priority

In January 1960, two fearless oceanographers eased themselves into a small steel sphere attached beneath a 50-foot submersible vessel and began an untethered descent to the bottom of the Pacific Ocean.

Almost five hours later, six-and-a-half miles down, under crushing pressure and surrounded by a pitch-black void, explorer Jacques Piccard and then U.S. Navy Lieutenant Don Walsh became the first people to reach the lowest known place on Earth, the Challenger Deep. For twenty minutes, the lights of their small craft, the Trieste, illuminated for humankind a place on our planet that had been dark for 150 million years.

Today, sixty years later, the United States is poised to lead a second era of bold innovation that will similarly reshape and expand human knowledge of the ocean, a priority for President Trump and

Robot research vessel to set off on epic ocean voyage of discovery

On the 400th anniversary of the start of an epic voyage from England to the New World aboard the Mayflower, an autonomous, solar-powered marine research vessel is due to launch on a mission to gather environmental data about the ocean.

Two years in the making, the Mayflower Autonomous Ship sets off from Plymouth in Devon today on six months of sea trials ahead of an Atlantic crossing attempt next year, a voyage based on the route taken by the Pilgrims in 1620.

As its moniker suggests, there will be no human captain at the helm, but an artificial intelligence navigation system developed by MarineAI and based on technologies from computing giant IBM. This AI Captain makes use of data from onboard radar, GPS, AIS, nautical charts, attitude sensors, a fathometer, a vehicle management system and weather data from The Weather Company.

“Able to scan the horizon for possible hazards, make

Mapping Technology Reveals Channels of Warm Water Under Florida-Sized Glacier | Smart News

New research shows that a Florida-sized block of ice in Western Antarctica called the Thwaites Glacier is sitting on top of large channels that may allow warm ocean water to melt it from the bottom, Carolyn Gramling reports for Science News.

Two new studies, both published in the journal Cryosphere, provide a detailed map of the glacier’s two ice shelf regions and the ocean floor in front of and underneath them. As one of the largest glaciers in Antarctica, the Thwaites Glacier is the subject of close study—if the entire glacier melted, it would cause ocean levels to rise by 25 inches. When the new maps are incorporated into models of Thwaites’ melting, that will show whether the deep trenches might cause the glacier to collapse sooner than previously predicted.

“Understanding that process and how these cavities evolve will be key to understanding how Thwaites and western Antarctica will

Ocean Acidification Causing Coral ‘Osteoporosis’ On Iconic Reefs

WOODS HOLE, Mass., Aug. 27, 2020 /PRNewswire/ — Scientists have long suspected that ocean acidification is affecting corals’ ability to build their skeletons, but it has been challenging to isolate its effect from that of simultaneous warming ocean temperatures, which also influence coral growth. New research from the Woods Hole Oceanographic Institution (WHOI) reveals the distinct impact that ocean acidification is having on coral growth on some of the world’s iconic reefs.

In a paper published Aug. 27, 2020, in the journal Geophysical Research Letters, researchers show a significant reduction in the density of coral skeleton along much of the Great Barrier Reef–the world’s largest coral reef system–and also on two reefs in the South China Sea, which they attribute largely to the increasing acidity of the waters surrounding these reefs since 1950.

“This is the first unambiguous detection and attribution of ocean acidification’s impact on coral

Stark warning for Invercargill, 30 years on from the Ocean Beach closure

A former mayor has offered up a stark warning for Invercargill suggesting there is a 30-year economic recovery ahead if the Tiwai Point aluminum smelter closes in 2021.

Justin Lester was Wellington’s mayor from 2016 through to 2019 but now works for Dot Loves Data, a data analytics company.

Lester, 41, grew up with his mother and two brothers at a Tramway Rd statehouse in Invercargill and openly admits it was humble financial beginnings.

He has a soft spot for south Invercargill and it’s prompted him to hover the microscope over the state of his old stomping ground.

Scorched earth investing, a new ocean fund, and the $1.75 million elephant

By David Callaway, Callaway Climate Insights

. . . . A smoky, orange haze kicks off the beginning of autumn this morning in the Bay Area as red flag fire and evacuation warnings, forced power outages, earthquakes and high winds cast an end-of-times pall over much of California. More than two million acres have burned already this season and we haven’t even hit the October peak yet.

You can’t blame it all on air conditioners, but the surge in energy usage as the recent heat wave (116°F. in Napa County) hit is certainly one of the reasons for the blackouts, and one of the most interesting investing opportunities for those looking on how to play the climate emergency.

HOW TO KNOW A TRUSTWORTHY RETAILER

It is important to note where to buy electronics safely to avoid unnecessary heartbreak. Just because a retailer has a friendly website, that does not mean the retailer keeps digital criminals away from your financial information. In reality, they may even be fraudulent!

Setting up a good website nowadays is incredibly simple. Increasing freelancing sites also means that anyone can easily hire a worker to create an attractive looking page, even if it does not actually have any of the proper security features to support online shopping.

6 Signs of a Trustworthy Retailer

1.   A stable website

Unfortunately, several fake retailers are just waiting for you to visit their website so they can infect your computer with malware or steal your data. Do not use merely etailer because they have the lowest price! Find the right phishing filter for your preferred browser, and stop shopping at any sites that cause … Read More

how technology is transforming the logistics industry

Most obviously, future cargo ships dispense with crew quarters, so Rolls’s sketches for  autonomous vessels allow for containers to be stacked, and fuel burned, more efficiently – up to 15pc more efficiently.

Such savings add up given that there are 96,000 merchant vessels in the world, carrying around 90pc of global trade that is relentlessly growing. Container port traffic rose from 225m TEUs in 2000 to 792m in 2018.

According to the International Chamber of Shipping, maritime trade accounts for 3pc of global greenhouse emissions, emissions which the International Maritime Organisation, has vowed to reduce by 40pc by 2030 and 70pc by 2050.

Unlike cars, however, much of that emissions reduction will have to be achieved by sleeker ship design, smart navigation (using currents and tides), and even upgrading propellers rather than batteries.

Recent calculations show that to complete a 31 day-trip from Asia to Europe the OOCL Hong Kong

Two Antarctic glaciers are breaking up and it could have major consequences for sea level rise

Satellite images show that two important glaciers in the Antarctic are sustaining rapid damage at their most vulnerable points, leading to the breaking up of vital ice shelves with major consequences for global sea level rise.

Thwaites Glacier

The Pine Island and Thwaites glaciers, which sit side by side in West Antarctica on the Amundsen Sea, are among the fastest changing glaciers in the region, already accounting for 5% of global sea level rise. Scientists say the glaciers are highly sensitive to climate change.

A new study, published in the Proceedings of the National Academy of Sciences on Monday, found that the glaciers are weakening at their foundations and this damage over the past few decades is speeding up their retreat and the possible future collapse of their ice shelves.
