OCEAN POLLUTION : EPIC RAIN STORMS, RIVERS, and CRUISE SHIPS

As we wait on a deluge of rain, possibly as much rain as is usually expected in a six month period, in just two or three days, as people in various parts of Southern California - Ventura County, Sun Valley in the San Fernando Valley, and Long Beach in Southern Los Angeles County, are asked to evacuate or be prepared for flooding, I'm confident that the home I live in will not flood.  However, these storms always end in pollution being rushed into the ocean.  Two rivers, the San Gabriel and the Los Angeles empty into the Pacific not far from here. Rivers are the way that most plastic pollution enter the ocean.  However, I also believe that cruise ships are using the ocean as a toilet and dump.  I believe that the massive ships that hold thousands of passengers are responsible for killing marine animals both by dumping, by collision, and by fuel pollution.

Intense rainstorms are the result of Climate Change.  Here at Siren's Link to Sea BlogSpot, I use the term Climate Change rather than Global Warming, because I'm not entirely convinced that we aren't actually moving into another Ice Age.

MALE SEA LIONS HAVE GOTTEN BIGGER OVER THE LAST FIFTY YEARS! UNIVERSITY OF CALIFORNIA MARINE SCIENCE

Usually as a population grows, the sea lions get smaller.  However just published in Current Biology, is a report from University of California at Santa Cruz.

Excerpt:  It's counterintuitive.  You would expect that their body size would decrease as dietary resource competition intensified," said coauthor Paul Koch, professor of Earth and Planetary Sciences at UCSC.

The number of California sea lions has increased dramatically since the Marine Mammal Protection Act was passed in 1972.  In parts of their range, the sea lions may now be approaching the ecological "carrying capacity," the largest number of animals an ecosystem can support.

NEWS-UCSC EDU : 2024 SEA LIONS

Excerpt: "We found that the male California sea lions have expanded their ecological niche, which means they are now foraging on a more diversified group of prey and expanding the places where they are foraging on a more diversified group ogf prey and expanding the places where they are foraging," Valenzuela-Toro said.  "Apparently they are now going farther north than they used to.....

**** Scientists looked at the skulls of sea lions...

TERRIBLY INJURED HUMPBACK WHALE

Excerpt:

The whale, BCX1232, also called Moon, was spotted recently off the Kona coast by the crew of the Hawaiian Adventures Kona. When she was sighted in B.C. waters, experts said she would likely not make it to the warmer Hawaii ocean due to her severe spinal injury. However, she made the more than 4,000-mile migration once again. Now, experts are very worried about her condition, which they believe was the result of a ship strike.

HOW LONG DOES IT TAKE GARBAGE TO BREAK DOWN?

Taking your trash home and putting it in the proper container - recycling plastic and aluminum cans is a start - is the easiest and best thing you as a person can do to keep that out of the water.

Take photos or make memories when looking around in low-tide tide pools!

Stop buying plastic junk that breaks - including toys - that end up in our landfills for hundreds of years...

IT'S TIME TO DONATE YOUR OLD SWIM SUITS TO A POOL THAT PROVIDES SUITS TO LOW INCOME MERMAIDS

Last year I made use of a large public swimming pool throughout the summer.  I love this pool because it's not crowded and it doesn't do lanes, so I can freestyle all over the pool without much worry that I'll clash in a lane or accidently hit someone else while I do my thing.

Mid-season I was there when a number of children who had the money to get in but did not have proper swimming suits got turned away.  Considering how underutilized this pool is, I asked what the problem was.   I mean WHAT A SHAME that they wanted to exercise and cool off in the water on a terribly hot day. These kids wanted to swim in shorts, or maybe shorts, bra, and a T- Shirt.  These kids might actually show up showered and in clean clothes, but an official swimsuit this is not.  Frankly, much of the underwear that is sold for women these days is almost as good if not better than what is sold for swim wear.

I've bought suits at thrift stores that appeared new myself.  One season when I was swimming indoors a few times a week I experienced how fast the chlorine in the water could destroy the fabric and elastic quickly, even if I rinsed it out there and soaked it in soapy water as soon as I got home.

I brought some information on some thrift shops that seem to have swim suits for sale that appear previously unused, such as having the sanitary panel intact, to the pool.  The management there thanked me for that and said she would pass it on  I also located a nearby charity that gave clothes away for free to people once a week and brought some fliers.

Yes swim suits are INTIMATE clothing...

But if you bought a suit that you cannot wear because it no longer fits that is in very good condition, consider donating it.

DID YOU MISS THE FEEDING FRENZY OFF THE COAST OF SOUTH AFRICA?

DAILY MAIL - HUMPBACK WHALES FEEDING OFF SOUTH AFRICAN COAST  go to this link to see videos of film taken from the sky of 60 plus eating fur seals and anything else in their path.  The seals look tiny next to their predator.

The pod was composed of humpbacks that came for miles...

YOU EAT FISH? ARE YOU CONTRIBUTING TO THE EXTINCTION OF SPECIES?

According to SEAFOOD FOR THE FUTURE ORG, which is part of the nonprofit, AQUARIUM OF THE PACIFIC  http://www.aquariumofpacific.org/seafoodfuture  THE WORLD HUMAN POPULATION IS EXPECTED TO EXCEED 9.5 BILLION by 2050.  Seafood is among the healthiest sources of protein on the planet.  Wild capture seafood harvests have LEVELED OFF and CANNOT MEAN THE DEMAND.... More than # BILLION people on the planet DEPEND ON SEAFOOD as their primary source of protein...

and WE HAVE THE TECHNOLOGY and SCIENTIFIC KNOWLEDGE to PRODUCE
ENVIRONMENTALLY RESPONSIBLE FARMED FISH.

It's called AQUACULTURE!

Go to this link and read about eating jelly fish, and the smallest porpoise on earth that is about to go extinct...the VAQUITA.

Fishing practices DO effect all ocean life.

SHARKS OF THE PACIFIC OCEAN - THEY MAKE THEIR WAYS UP THE COAST AND INTO RIVERS

You've been reading more and more about SHARKS, shark attacks (chomping surfboards and surfers), sharks swimming north along the Pacific Coast, sharks making their way into rivers.

Sharks are survivors, we have drought on land and extremely hot temperatures that are effecting ocean currents -so -


so read about SHARKS! SHARK RESEARCH COMMITTEE - INDIGENOUS

BLACK WAVE - A GRIPPING TRUE STORY ABOUT A FAMILY THAT TOOK TO THE SEAS and ENDED IN DISASTER : SIREN's BOOK REVIEW

 
John and Jean Silverwood loved the ocean and sailing, and so they worked hard, saved money, bought a fifty-five foot catamaran they named Emerald Jane, took their four children out of school for a two year sailing adventure.  Their true adventure story is wonderfully written, an exciting page turner, but as the cover says, it ended in a disaster.  Their catamaran was broken apart on a coral reef, and when the mast fell across John's legs, and almost severed one of them, he would beat death due to a rescue by isolated island people, but would loose his leg.  In their very modern story is also enter twinned the story of the last ship that the same coral reef claimed in the 19th century and the 21st century invention that signaled to satellites in space to a rescue station in San Diego, even though they were in such an isolated area near French Polynesia that they were 250 miles away from the nearest island.
 
Part of my summer reading this year, you still have time before school starts to pick up this one and take the adventure with them.

PUBLIC LEGAL NOTICE - SIRENS LINK TO SEA BLOGSPOT has no afficiation with the same named YOUTUBE STATION

AND I THINK THE OWNER OF THAT SITE IS A REAL STINK POT TO USE THE TERM BLOGSPOT, and may be actually be legally in the wrong for thereby publically leaning on years of my hard work and hurting my reputation. 

I think you and your videos STINK. 

How about that from SIREN!?

I think YOUTUBE/GOOGLE should shut you down!

BALEEN WHALE HEARING - MYSTERY SOLVED!

DISCOVERY - BALEEN WHALES HEARING MAY BE SOLVED  by Richard Farrell full article

EXCERPT:

San Diego State University biologist Ted W. Cranford and University of California, San Diego engineer Petr Krysl created a three-dimensional computer model of a baleen whale's head, one that would include the skin, skull, eyes, ears, tongue, brain, muscles, and jaws.
For their test subject, the pair obtained the head of a fin whale that beached in 2003 and then ran it through an X-ray CT scanner.

Once they had the head scan, Cranford and Krysl ran simulations of how sound travels through the whale's brain. To get the detail they needed, they used a technique called finite element modeling, in which the data representing the head parts and skull were separated out into tiny elements by the millions, the relationships between the elements tracked.

Sound can reach a baleen whale's ear bones on its skull in two ways: the sound's pressure waves can go through the animal's soft tissue; or the sounds can vibrate along the skull itself, in a process called "bone induction."

The problem with the soft-tissue, pressure, route, the researchers said, is that it's ineffective when sound waves are longer than the whale's body. But with the bone induction process, those longer waves become amplified as they vibrate in the creature's skull.

The scientists' computer modeling showed that the bone induction process was about four times more sensitive to low-frequency sounds than the soft-tissue, pressure mechanism.
What's more, their modeling predicted that bone induction is 10 times more sensitive to the lowest frequencies used by fin whales (10 Hz-130 Hz).
