Marine Researchers Collecting Global Symphony of the Sea

Experts from nine countries are planning to collect and combine aquatic animal sounds for a global library. Scientists in Australia believe an undersea chorus of mammals, fish and some invertebrates will help them gauge the health of marine ecosystems.

Songs by bearded seals and the “boing” of a minke whale are part of a global collection being put together for the first time by a team of international researchers.

The samples are stored in the individual libraries of various institutions, but never before have they been curated in a single collection.

All marine mammals, including the humpback whale, are thought to emit sounds, along with many fish and invertebrates. A new data bank aims to use these recordings to measure biodiversity and the health of ecosystems.

Miles Parsons, a researcher at the Australian Institute of Marine Science and the lead author of a report on the databank, says animal sounds can indicate the health of an ecosystem.

“When you are talking about things like soundscapes, there is a lot of work recently that has been done to tease out the acoustic characteristics of a soundscape to be able to identify the type of habitat that it is and even start to look at the quality of the habitat. There has been some work recently where they have looked at the difference between degraded coral reefs and healthy coral reefs and the differences in the soundscapes that you have between those. There’s lots of different applications that you can get from this, from passive acoustic monitoring.”

The mulloway is one of the loudest fish in the world. Of the 34,000 known species of fish, only 1,000 have had their sounds documented.

Researchers use highly sophisticated ocean hydrophones, or underwater microphones, to record sounds. Amateur divers have used underwater cameras to record the squeaks and groans of marine life, and they submit their findings to academics.

And some birds reportedly make underwater noises.

Scientists believe that pollution and warming temperatures are changing underwater acoustics.

The research paper “Sounding the Call for a Global Library of Biological Underwater Sounds” was published in the journal “Frontiers in Ecology and Evolution.”

It is a collaboration between experts from various countries, including Britain, China, New Zealand and the United States.

California Adopts Nation’s First ‘Endemic’ Virus Policy

California Governor Gavin Newsom on Thursday announced the first shift by a state to an endemic approach to the coronavirus pandemic. He said it emphasizes prevention and quick reactions to outbreaks over mandates, a milestone nearly two years in the making that harkens to a return to a more normal existence.

Newsom said the approach, which includes pushing back against false claims and other misinformation, means maintaining a wary watchfulness attuned to warning signs of the next deadly new surge or variant.

“This disease is not going away,” he told The Associated Press in advance of his formal announcement. “It’s not the end of the ‘war.’ “

A disease reaches the endemic stage when the virus still exists in a community but becomes manageable as immunity builds. But there will be no definitive turn of the switch, the Democratic governor said, unlike the case with Wednesday’s lifting of the state’s indoor masking requirements or an announcement coming February 28 of when the school mask-wearing mandate will end.

And there will be no immediate lifting of the dozens of remaining executive emergency orders that have helped run the state since Newsom imposed the nation’s first statewide stay-home order in March 2020.

The World Health Organization declared the COVID-19 outbreak a pandemic on March 11, 2020, and with omicron fading in many parts of the world some countries have begun planning for the endemic stage.

Newsom’s administration came up with a shorthand acronym to capsulize key elements of its new approach: SMARTER. The letters stand for Shots, Masks, Awareness, Readiness, Testing, Education and Rx, a common abbreviation for prescriptions and a reference to improving treatments for COVID-19.

Greater watchfulness

Living with COVID-19 under Newsom’s plan means boosting the state’s surveillance, including increased monitoring of virus remnants in wastewater to watch for the first signs of a surge. Masks won’t be required but will be encouraged in many settings.

If a higher level of the virus is detected, health officials will analyze its genotype to determine if it is a new variant. If so, state and federal officials have a goal to determine within 30 days if it responds to existing tests, treatments, and immunities from vaccines or prior infections.

Testing and staffing in the affected area will be increased, including temporary medical workers to assist strained hospitals.

The plan sets specific goals, such as stockpiling 75 million masks, ramping up to delivering 200,000 vaccinations and 500,000 tests a day, and adding 3,000 medical workers within three weeks in surge areas through ongoing contracts with national registry companies.

Dr. George Rutherford, an epidemiologist and infectious-disease control expert at the University of California-San Francisco, has urged a cautious approach to lifting mandates. He saw drafts of Newsom’s plan and likes it.

“They have a long-term plan that’s trying to capture these events as they occur and has the supply chain stuff you need to have pre-positioned so that we can move forward in a thoughtful but rapid way to control new outbreaks,” he said.

Avoiding business closures

California’s health secretary, Dr. Mark Ghaly, said one of the goals is to avoid business closures and other far-reaching mandates. However, he said, the state’s requirement that schoolchildren be vaccinated against coronavirus by fall remains in effect.

The plan calls for a continued emphasis on efforts in vulnerable and underserved populations that have experienced disproportionately high death rates. And it includes new education, including “myth-buster videos” to fight misinformation and disinformation and help interpret ever-evolving precautions for a confused public whiplashed by safeguards that seemingly shift by the day and vary across county lines.

It relies on continued testing sites including in schools; more over-the-counter virus tests; and building and tracking strategic stockpiles of testing kits, surgical and K95 masks, hospital gowns and gloves, and ventilators. In coordination with the federal government, it calls for a first-in-the-nation study of the pandemic’s direct and indirect long-term impacts on both people and communities.

Newsom and Ghaly said constant monitoring will be useful in spotting other similar respiratory airborne diseases, while leading to improvements in California’s overall public health system.

All this will cost billions, much of it already outlined in the $3.2 billion pandemic response package Newsom sought as part of his budget last month. That includes $1.9 million that lawmakers already approved to boost staffing at hospitals and increase coronavirus testing and vaccine distribution, as well as existing money and anticipated federal funds.

His proposed budget also includes $1.7 billion to beef up the state’s health care workforce, with more investment in increased laboratory testing capacity, data collection and outbreak investigation.

Emergency orders

Newsom defended keeping in place some of his executive emergency orders, which he said most recently have allowed the state to quickly bring in temporary medical workers and to quickly distribute more than 13 million home test kits to schools.

The omicron surge is ebbing as quickly as it spiked in December, with new cases falling back to near pre-surge levels. Hospitalizations and intensive care cases were also falling, and the state’s forecasting models predict a continued gradual easing over the next month.
