When ships pass, whales eat less, says study

PARIS: Noise from ships impedes humpback whales from foraging for food, and could have long-term impacts on the health of these majestic creatures, according to a study released Wednesday.
Shipping lanes overlapping with the coastal migratory paths of whales create a steady source of underwater noise pollution.
Earlier research has shown how this can interfere with the behavior of so-called toothed whales, a category that included dolphins, as well as killer and sperm whales, that emit sonar-like pings to locate prey and communicate.
But very little was known about how the constant, low-frequency drone of ocean vessels might affect baleen whales, the other major category.
These include blue, humpback, right and bowhead whales.
To find out, a team of scientists led by Hannah Blair of Syracuse University in New York attached non-intrusive sensors to 10 humpbacks in the western North Atlantic.
The devices not only picked up and recorded all the sounds heard by the whales, but also tracked their underwater movement.
Humpbacks have a wide array of foraging techniques used to consume a large number of small prey, including one maneuver scientists call the “bottom side-roll.”
To feed on sand lance, bottom-dwelling eel-like fish, “the whale dives and scrapes along the ocean floor,” explained Blair.
A humpback can deep-dive for up to 30 minutes.
“At the same time, it rolls regularly onto its side and opens its mouth, scooping up the fish hidden in the sand,” especially at night, she told AFP.
Every barrel roll is like a meal.
The study found that half of the whales, all of them adult females, failed to execute these important side-rolls in the presence of ship noise on at least one of their deep dives.
Researchers can only speculate as to why.
The humpback may have perceived the ships as a threat. It is also possible, they said, that the prey reacted to the noise too, scattering or digging more deeply into the sand.
Humpbacks have been dealing with chronic noise from ships for decades, and have shown some capacity to adapt.
The new findings, however, “suggest that the whales are unable to completely adjust to this disturbance,” the study concluded.
The paper appears in Biology Letters, a journal published by Britain’s de-facto academy of sciences, the Royal Society.


US eases restrictions on China’s Huawei to keep networks, phones operating

US eases restrictions on China’s Huawei to keep networks, phones operating

  • The company is still prohibited from buying American parts and components to manufacture new products without license approvals
  • Out of $70 billion Huawei spent buying components in 2018, some $11 billion went to US firms
WASHINGTON: The US government on Monday temporarily eased some trade restrictions imposed last week on China’s Huawei, a move that sought to minimize disruption for the telecom company’s customers around the world.
The US Commerce Department will allow Huawei Technologies Co. Ltd. to purchase American-made goods in order to maintain existing networks and provide software updates to existing Huawei handsets.
The company is still prohibited from buying American parts and components to manufacture new products without license approvals that likely will be denied.
The US government said it imposed the restrictions because of Huawei’s involvement in activities contrary to national security or foreign policy interests.
The new authorization is intended to give telecommunications operators that rely on Huawei equipment time to make other arrangements, US Secretary of Commerce Wilbur Ross said in a statement.
“In short, this license will allow operations to continue for existing Huawei mobile phone users and rural broadband networks,” Ross added.
The license, which is in effect until Aug. 19, suggests changes to Huawei’s supply chain may have immediate, far-reaching and unintended consequences for its customers.
“The goal seems to be to prevent Internet, computer and cell phone systems from crashing,” said Washington lawyer Kevin Wolf, a former Commerce Department official. “This is not a capitulation. This is housekeeping.”
Huawei, the world’s largest telecommunications equipment maker, declined to comment.
The Commerce Department said it will evaluate whether to extend the exemptions beyond 90 days.
On Thursday, the US Commerce Department added Huawei and 68 entities to an export blacklist that makes it nearly impossible for the Chinese company to purchase goods made in the United States.
The government tied Huawei’s addition to the “entity list” to a pending case accusing the company of engaging in bank fraud to obtain embargoed US goods and services in Iran and move money out of the country via the international banking system. Huawei has pleaded not guilty.
Reuters reported Friday that the department was considering a temporary easing, citing a government spokeswoman.
The temporary license also allows disclosures of security vulnerabilities and for Huawei to engage in the development of standards for future 5G networks.
Reuters reported Sunday that Alphabet Inc’s Google suspended business with Huawei that requires the transfer of hardware, software and technical services except those publicly available via open source licensing, citing a source familiar with the matter.
Google did not immediately respond to a request for comment on the new authorization.
Out of $70 billion Huawei spent buying components in 2018, some $11 billion went to US firms including Qualcomm Inc. , Intel Corp. and Micron Technology Inc.
“I think this is a reality check,” said Washington trade lawyer Douglas Jacobson. “It shows how pervasive Huawei goods and technology are around the globe and if the US imposes restrictions, that has impacts.”
Jacobson said the effort to keep existing networks operating appeared aimed at telecom providers in Europe and other countries where Huawei equipment is pervasive.
The move also could assist mobile service providers in thinly populated areas of the United States, such as Wyoming and eastern Oregon, that purchased network equipment from Huawei in recent years.
John Neuffer, the president of the Semiconductor Industry Association, which represents US chipmakers and designers, said in a statement that the association wants the government would ease the restrictions further.
“We hope to work with the administration to broaden the scope of the license,” he said, so that it advances US security goals but does not undermine the industry’s ability to compete globally and remain technology leaders.
A report on Monday on the potential impact of stringent export controls on technologies found that US firms could lose up to $56.3 billion in export sales over five years.
The report, from the Information Technology & Innovation Foundation, said the missed opportunities threatened as many as 74,000 jobs.
Wolf, the former Commerce official, said the Huawei reprieve was similar to action taken by the department in July to prevent systems from crashing after the US banned China’s ZTE Corp, a smaller Huawei rival, from buying American-made components in April.
The US trade ban on ZTE wreaked havoc at wireless carriers in Europe and South Asia, sources told Reuters at the time.
The ban on ZTE was lifted July 13 after the company struck an agreement with the Commerce Department that included a $1 billion fine plus $400 million in escrow and replacement of its board of directors and senior management. ZTE, which had ceased major operations as a result of the ban, then resumed business.
