WHEN THE OCEAN SENDS A CRY FOR HELP : SAN PEDRO'S MARINE MAMMAL CARE CENTER THE FOCUS OF THIS PERSONAL EXPERIENCE STORY
Excerpt: An unusually early and toxic algae bloom has caused a massive domoic acid poisoning event affecting pinnipeds, dolphins and seabirds all along the Southern California coast. While there have been other serious outbreaks in the 24 years since DA was first identified on the West Coast — the summer of 2023 was also harrowing — the early arrival and the morbid intensity of this event are straining local resources. Ash and runoff from the fires may be exacerbating the natural phenomenon, leading to heartbreaking scenes of dolphins stranding on public beaches, gasping for breath.

HILTON HEAD BEACHED SPERM WHALE : WHALE HELP
ISLAND PACKET :HILTON HEAD BEACHED SPERM WHALE
Excerpt: Like the beached whale on Hilton Head Island, live whales usually only beached themselves if they’re sick, injured, or in otherwise poor health. One common cause of sickness is when the whale ingests marine debris, especially plastic. Whales can get entangled in fishing gear or get struck by boats. Sperm whales are an endangered species, and about four of them strand themselves on beaches across the Atlantic coast per year. George said there has been some increase in the number of whales washing up over the years, but it’s not known whether that’s due to an increase in sperm whale populations or an increase to the threats they face. Lentz said the average person can help endangered whales by making conscientious choices about the food they eat and the products the buy, and picking up their garbage on the beach.

DRONES RECORD HUNDREDS OF WHALES : CHANGES IN SIZE OF FEMALES AND CALVES : DROP IN BIRTHRATE : HEATWAVES EFFECT
SEATTLE TIMES : DRONES RECORD HUNDREDS OF WHALES by Brendan Rascius of McClatchy News
EXCERPT: ... scientists documented dramatic changes in the size of the mothers and calves and in humpback birthrates.Changes in size
Between 2018 and 2022, “a total of 2,410 measurements were taken from 1,659 individuals, with 405 repeat measurements from 137 lactating females used to track changes in maternal body volume over migration,” Martin van Aswegen, one of the study authors, said in a news release from the University of Hawaii at Manoa.
In six months, they decreased in body volume by 17% on average. Specifically, the mothers off Hawaii — where the whales breed — lost about 214 pounds of blubber each day.
Comparatively, nonpregnant and pregnant females off Alaska — where the whales feed — gained size much faster than new mothers, putting on weight between two and six times the rate of lactating females.
Calves, in contrast, rapidly put on weight. They increased their body volume by about 395%, and their length increased by nearly 60%.

OCEAN CURRANTS STALLING? CHANGING? WEATHER MOVING TOWARDS AN ICE AGE?
Excerpt: A new study by experts at University of Gothenburg and the German Alfred Wegener Institute reveals that rapidly melting freshwater ice in the Arctic could be one cause. This melted ice could weaken or even cause a collapse of the Atlantic Meridional Overturning Circulation (AMOC) – Earth's vast system of ocean currents.
Described as 'the conveyor belt of the ocean', AMOC transports warm water near the ocean's surface northwards from the tropics up to the northern hemisphere, keeping Europe, the UK and the US east coast temperate.
If and when AMOC does collapse, much of the northern hemisphere, including Europe and North America, could experience harsh, freezing cold winters.
But study author Dr Céline Heuzé, senior lecturer in climatology at the University of Gothenburg, said it's 'scary' that the exact effects of weaker global ocean circulation are as yet unknown.

OCEAN ACIDIFICATION TICKING TIME BOMB : SEA LIFE CRISIS
THE GUARDIAN : SEA ACIDITY CRISIS TICKING TIMEBOMB
Excerpt: It found that by 2020 the average ocean condition worldwide was already very close to – and in some regions beyond – the planetary boundary for ocean acidification. This is defined as when the concentration of calcium carbonate in seawater is more than 20% below preindustrial levels.
The deeper in the ocean they looked, the worse the findings were, the scientists said. At 200 metres below the surface, 60% of global waters had breached the “safe” limit for acidification.
“Most ocean life doesn’t just live at the surface,” said PML’s Prof Helen Findlay. “The waters below are home to many more different types of plants and animals. Since these deeper waters are changing so much, the impacts of ocean acidification could be far worse than we thought.”

2025 UNITED NATIONS OCEAN CONFERENCE TAKING PLACE NOW
WMO INTERNATIONAL : UNITED NATIONS OCEAN CONFERENCE 2025 NOW
Excerpts: The UN Ocean Conference from 9 to 13 June, is co-hosted by the governments of France and Costa Rica. It is expected to adopt a political declaration and registry of voluntary commitments – called the Nice Ocean Action Plan to conserve and sustainably use the ocean” in support of Sustainable Development Goal 14 on life above and below the water.French President Emmanuel Macron and Costa Rican President Rodrigo Chaves Robles of Costa Rica joined UN secretary-General Antonio Guterres in calling for more science-based action to protect ocean health which is so vital to planetary health.
The ocean absorbs more than 90 percent of excess heat from human activities. Ocean warming and glacier melt is accelerating sea-level rise. Record ocean temperatures and acidification are inflicting severe and long-lasting damage.
This is having a tsunami-like impact on sustainable development of the ocean and resulting in billions of dollars of damage to the Blue Economy.

The rise we saw in 2024 was higher than we expected,' said Josh Willis, a sea level researcher at NASA's Jet Propulsion Laboratory in Southern California.'Every year is a little bit different, but what's clear is that the ocean continues to rise, and the rate of rise is getting faster and faster.'
Since 1993, global sea levels have risen by a staggering 3.97-inches (10.1cm).
And if they continue to climb at this rate, hundreds of densely populated cities around the world could be plunged underwater. Excerpt: According to NASA, this 'unexpected' increase was due to an unusual amount of ocean warming, combined with meltwater from land-based ice such as glaciers.

JAPANESE SARDINES IN CALIFORNIA? NOAA FISHERIES REPORTS : LINK TO PODCAST
FISHERIES NOAA : PODCAST JAPANESE SARDINES IN CALIFORNIA
Excerpt: In 2022, Dr. Gary Longo detected Japanese sardines swimming in the eastern Pacific, off the coast of California. This was the first time they’d ever been seen here—their normal range is in the western Pacific from Korea to Russia, thousands and thousands of miles away. It was a shocking discovery. Sardines are incredibly important to the California current ecosystem and are a key forage fish across the globe.
On this episode of Dive In with NOAA Fisheries, we scratch at this mystery of Japanese sardine appearing in U.S. waters. How did they get here? What does it mean for the native Pacific sardine? Are they staying? (Spoiler alert: so far, yes.)
We hear from Dr. Longo, a research scientist at NOAA’s Southwest Fisheries Science Center and one of the authors of a new study documenting this discovery. The authors suggest marine heatwaves that warmed the North Pacific over the last decade might have opened a corridor of favorable habitat, which the Japanese sardines followed across the ocean.

WRECKAGE OF THE WESTERN RESERVE FOUND IN LAKE SUPERIOR BY MARINE SONIC TECHNOLOGY : UNDISCOVERED FOR 132 YEARS
There was one survivor...
Excerpt:
The Great Lakes can be more dangerous than the oceans
The Great Lakes have claimed thousands of ships since the 1700s. Perhaps the most famous is the Edmund Fitzgerald, an ore carrier that got caught in a storm in November 1975 and went down off Whitefish Point within 100 miles of the Western Reserve. All hands were killed. The incident was immortalized in the Gordon Lightfoot song, “The Wreck of the Edmund Fitzgerald.”
Assistant Wisconsin State Climatologist Ed Hopkins said that storm season on the lakes begins in November, when warm water meets cold air and winds blow unimpeded across open water, generating waves as high as 30 feet. The lakes at that time can be more dangerous than the oceans because they’re smaller, making it harder for ships to out-maneuver the storms, he said.
NBC NEWS : EXPLORERS FIND WRECKAGE OF SHIP "WESTERN RESERVE"
Excerpt: The brothers towed a side-scanning sonar array behind their ship. Side sonar scans starboard and port, providing a more expansive picture of the bottom than sonar mounted beneath a ship. About 60 miles northwest of Whitefish Point on the Upper Peninsula, they picked up a line with a shadow behind it in 600 feet of water. They dialed up the resolution and spotted a large ship broken in two with the bow resting on the stern.

WATCHING A SMALL AQUARIUM TANK FISH DIE : AN UNNATURAL AND IMPRISONED LIFE ALONE
Over the years I've become increasingly against home aquariums for fish that grow bigger. I recently saw a fish that had lived alone in an aquarium die. It was horrible. This fish had lived alone for the amusement of the few people who actually even bothered to notice it. It swum around a background, plastic made-for-aquarium sea weeds and fake castles and such, and awaited feeding. I would walk by and go eye to eye with it and sometimes move my fingers as if they were fins and the fish would follow.
I heard that this fish had been in the tank for ELEVEN YEARS and was ALONE because he "ATE ALL THE OTHER FISH IN THE TANK." Well in the sea, fish eat fish, but I wondered if perhaps this was because he had not been fed properly.... And was also in a tank TOO SMALL FOR HIM.
HIM ... it could have been a HER.
The fish started laying low to the bottom of the tank, barely upright.
It's eyes were covered in some sort of white film.
I immediately informed the owner I thought the fish was dying and to contact their aquarium service.
A week later the fish was clearly having trouble fish-breathing, it's gills working hard.
I had not seen air being pumped into the tank.
The walls of the tank had a green-black film on them.
As a result I'm clearly anti-aquarium tank.
Perhaps the small fish that never get too big can have a better tank life than this?
Other fish in the tank.
Real sea weed.

CRABS AND LOBSTERS FEEL PAIN UPON BEING BOILED ALIVE : SCIENTISTS CALL FOR A BAN
I have this idea that creatures of the sea have only recently been understood to be animals. What I almost never eat is sea food. Siren
EARTH COM : SCIENTISTS CALL FOR IMMEDIATE BAN ON BOILING THEM ALIVE
Excerpt: Dr. Lynne Sneddon, a zoophysiologist at the University of Gothenburg, believes it’s time we reconsider how we treat these animals.
“We need to find less painful ways to kill shellfish if we are to continue eating them. Because now we have scientific evidence that they both experience and react to pain,” she says.
Excerpt: Until now, the idea that crustaceans feel pain was mostly based on observational studies.
Researchers noticed that when crabs and lobsters were exposed to potentially harmful stimuli — like electric shocks or acids — they would touch the affected area or try to avoid the danger in subsequent encounters.
This behavior led many to believe they might be experiencing pain.
But the team at the University of Gothenburg took it a step further. PhD student Eleftherios Kasiouras led a study where they measured the activity in a shore crab’s brain using EEG-style recordings.

ICEBERG THE SIZE OF CHICAGO LET GO FROM ANTARTICA
Iceberg calving is a normal occurrence for ice shelves. However, factors such as warming air and water along with decreasing protective sea ice can accelerate calving and lead to collapse, as has happened to several ice shelves along the Antarctic Peninsula.
Observations made by explorers beginning in the early 1940s, and later by remote sensing, show that the George VI has been losing shelf ice. For now, the retreat has been gradual, aided by the stability provided by its unique location, sandwiched between the Antarctic Peninsula and Alexander Island. *** Siren here!

NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION REPORTS ON WARMEST FEBRUARY ON RECORD ADMIST FEDERAL FUNDING CUTS EFFECTING HUNDREDS OF EMPLOYEES
NCEI NOAA : GLOBAL CLIMATE CHANGE REPORT
Siren here! Look at those maps. Is your city going to be under water within your lifetime?
If you took your umbrella today, it may just be because of a scientific report from NOAA.
TIME MAGAZINE : THE TRUE COST OF NOAA CUTS - CLIMATE CHANGE
Excerpt: If you’ve ever avoided a hurricane, ducked a tornado, evacuated ahead of a wildfire, or merely relied on a weather forecast to take an umbrella to work, you likely have the National Oceanic and Atmospheric Administration (NOAA) to thank. As America’s—and indeed the world’s—leading weather and climate watchdog and the parent organization of the National Weather Service (NWS), NOAA runs a standing army of personnel and hardware on and off the planet to keep an eye on the Earth’s often stormy temperament. The agency owns or operates 13 weather satellites; manages more than 200 deep-water buoys: and gathers weather and climate information from a storm of data provided by no fewer than 10,600 state, local, and federal governments, as well as universities and private companies nationwide.Excerpt: But NOAA is now threatened. As the Associated Press and others have reported, the agency’s already stretched workforce of 13,000 people is facing a deep cut of more than 1,000 of those employees mandated by the Trump Administration—a move that follows an earlier purge of about 1,300 in late February. The personnel reductions not only imperil NOAA’s ability to carry out its core chore of tracking and warning about upcoming severe weather events, they also hamper its ability to conduct basic research into climate change—carried out to help humanity better prepare for the sweeping environmental upheaval already evident in a steadily warming world.

WHY DO YOU STAND UP FOR SCIENCE ? : ESSAYS WANTED
Graduate Admissions cut... PhD Grad's delayed...
ANNENEBERG MEDIA : SCIENTISTS UCLA USC PROTEST
Excerpt:
Margarid Turnamian, a clinical psychology graduate student at USC and organizer of the event, emphasized that funding cuts could be far-reaching because science is critical to everyday life.
“Science affects every single person’s life on a daily basis,” she said. “Everything that we use: from our cell phones to the roads that we drive on, to the foods that we eat, to the way that we communicate, is based in science.”
With the threat of federal funding cuts, Turnamian said she fears many people underestimate just how much they rely on scientific advancements. She pointed out that the economic argument against science funding — that it is not worth investing in — is misleading.
“At the rally on Friday, one of the speakers, Duke Kahn, who’s a professor of psychology at USC, brought up a great statistic that every $1 that goes to NIH funding is returned into the economy at like $2.50,” she said.

BIOLOGICAL DIVERSITY ORG : OCEAN PLASTICS POLLUTION
Excerpt: We're surrounded by plastic. It’s in the single-use packaging we discard, the consumer goods that fill our stores, and in our clothing, which sheds microplastic fibers in the wash.In the first decade of this century, we made more plastic than all the plastic in history up to the year 2000. And every year, billions of pounds of more plastic end up in the world's oceans. Studies estimate there are now 15–51 trillion pieces of plastic in the world's oceans — from the equator to the poles, from Arctic ice sheets to the sea floor. Not one square mile of surface ocean anywhere on earth is free of plastic pollution.
The problem is growing into a crisis. The fossil fuel industry plans to increase plastic production by 40 percent over the next decade. These oil giants are rapidly building petrochemical plants across the United States to turn fracked gas into plastic. This means more toxic air pollution and plastic in our oceans.
We need urgent action to address the global plastic pollution epidemic.
Unfortunately, plastic is so durable that the EPA reports “every bit of plastic ever made still exists.” All five of the Earth's major ocean gyres are inundated with plastic pollution. The largest one has been dubbed the Great Pacific Garbage Patch.

THE DEBRIEF : LOST WORLD UNDER THE PACIFIC?
Excerpt: An international team of geophysicists using a new imaging technique that measures the speed of seismic waves caused by earthquakes to locate the juncture of tectonic plates in the Earth’s mantle say they have discovered the remnants of what appears to be a “lost world” beneath the Pacific Ocean.... According to the published study, the team was particularly intrigued by one zone discovered beneath the western Pacific Ocean. That’s because there should be no material from subducted plates there “because it is impossible that there were subduction zones nearby in the recent geological history.”

CAL TECH : NEW TECHNOLOGY - EARTH'S PLATES
Excerpts: Caltech researchers have developed a new method to study the earth's structure deep beneath the surface, at the boundary between Earth's brittle crust and the underlying mantle, a region called the Mohorovičić discontinuity—Moho for short......On continents, the Moho can be found at depths ranging between 20 and 70 kilometers beneath the surface; in Southern California, the Moho is around 45 kilometers belowground. Attempts had been made to image it using conventional seismometers, but these efforts either yield low-resolution results, on the scale of tens of kilometers, or were prohibitively expensive. With the DAS method, researchers can easily observe the structure of the Moho over large regions at a resolution of a kilometer, providing a far more detailed look at this geologically important region.

It’s called the Gully, and it’s a marine protected area under Fisheries and Oceans Canada. More than 9 miles wide, the Gully is “the largest underwater canyon in the western North Atlantic,” the department says, and is filled with endangered and rare species. It was here that in 2009 researchers caught and brought to the surface a mysterious looking fish. The animal had a bulbous head, sleek body and gaping mouth, and was a dark brown, nearly black color, according to a July 24 Facebook post from Fisheries and Oceans Canada. “They sampled and analyzed its DNA,” the department said. “Back then, it did not match any known species and was left without a name.”

RARE NAUTILOIDS FOUND (FOSSILS MIGHT BE EASIER!) IN PALAU
ROVPLANET : AMAZING NAUTILOIDS
Excerpt: During a remotely operated vehicle (ROV) dive in the German Channel in Palau, the Ocean Exploration Trust (OET) witnessed four Palau nautilus individuals (Nautilus belauensis). These are the first sightings of nautiloids — the most primitive cephalopods — from E/V Nautilus after 1000+ ROV dives over the last 15 years of operations. This marine mollusk found in the Indo-Pacific is rarely photographed- let alone caught on video -and 2024’s expeditions represent the first of OET’s adventures within the nautilus’s expected distribution range. This expedition (NA169) was funded by NOAA Ocean Exploration via the Ocean Exploration Cooperative Institute.
Rare!
"Whenever you see a rare animal in the ocean, there is always a sense of awe. The nautilus isn't a new species, but there is still a certain magic to seeing it move in real-time across the ocean floor and respond to the ROV. And it has no idea that hundreds of humans are staring at it!" says Alice Chou, onboard Science Communication Fellow.

Be creative!
But perhaps you could do the Science Fact research first and then follow your creativity!
Will you write a graphic novel?
What about illustrating your book!

CALIFORNIA FIRES : SMOKE HUNDREDS OF MILES OUT OVER THE PACIFIC : IMPACT ON WHALES AND OTHER SEA CREATURES
Excerpt: OCEAN - A large influx of ash and debris, including metals and chemicals, enters waterways, especially following precipitation. This massive sediment load smothers the coastal ecosystem, covering coral reefs, resulting in significant habitat loss and, eventually, fish and invertebrate mortality. The resulting water cloudiness reduces light penetration necessary for plants to conduct photosynthesis. The influx of run-off, which includes nutrients, and sedimentation can induce harmful algae blooms that deplete oxygen levels and cause fish and other animal die-offs. Subsequently, ash and debris loads are spread wide by tides, currents, and winds, magnifying their effects though nearshore environments.

CAN FIREFIGHTERS USE OCEAN SALT WATER TO FIGHT THE CALIFORNIA FIRES?
The answer is that they do so, but in desperation, because the salt water is corrosive to equipment and the soil in which the salt water has been dumped is not friendly to plant life. Some areas where ocean water has been dumped to put out a fire remain barren of plant life for years. When urban sources for water are used up, fire fighters will use ocean water.
