Released last Friday, a digital reconstruction of the Titanic chronicles a never-before-seen view of the wreck that is “accurate to the rivet,” a statement says.

A mysterious ocean glow reported for over 400 years has stumped scientists. A new study could offer clues.

From @CNN: "For over 400 years, sailors have reported a mysterious phenomenon in which the ocean appears to glow as far as the eye can see."

Go Deep to Find Your Bliss.
Life can often feel chaotic. Unbalanced. Stressful.
Try and see that it is just on the surface.
Stop frantically treading water just to stay
afloat amidst the craziness.
Instead, choose to go deep.
Deep down, where the restless tides abate.
Deep within, where inner calm resides.
Where bliss can be found.

On a watercolor background of blue, two thirds of which is water with pale vertical stripes and the top one third a highly textured sky with yellow sun. Frantically treading water at the surface, an orange sullen creature with yellow horns peeks above. At the very bottom of the picture, deep within the water and tied with a string, a pinkish balloon gently floats. Inside it is a red heart. NOTE: This description created especially for my lovely blind friend, Georgiana. :-)

The Gentle Mermaid
The mermaid floats without a care in her peaceful, green, watery world. :-)

The Gentle Mermaid
Background of mostly green/teal washes of color. In the foreground, a rusty-orange colored mermaid gently floats by. Her body is decorated with swirling patterns. Eyes closed, with the touch of a smile, she dreams of peace. Around her, muted multi-colored bubbles surround her, filled with softly geometric circles and shapes. In one hand, she holds a four petaled flower.

It was not a landscape through which you could quickly move, power walk over, run across, rush past.

But then again, it was not a landscape that you wanted to spend little time in. It invited -- nay, demanded, in a friendly, open fashion -- you to linger.

"Must you," it murmured, "always be in a hurry?"

Ocean notes. #ocean #swim #MerewetherBaths #NewcastleNSW

Looking across the blue green water in the main pool at the metal railing along the northern edge. Distant figures are outlined against the fence and blue sky: standing, sitting, swimming and sunbathing. It reminds me a little of a musical notation.

Adjusting the goggles. #ocean #swim #MerewetherBaths #NewcastleNSW

A swimmer with his back to the camera has his hands lifted to adjust his goggles. He's standing chest deep in dark green blue water next to the 10th concrete lap lane marker, the rest of the markers lined up in a row like an odd toothy smile.

Sitting on the wall of the baths. #ocean #swim #MerewetherBaths #NewcastleNSW

Looking southwards along the weathered white concrete wall of the baths, 2 guys in boardies are sitting on the edge, with their legs in the water. The water is a pale green near the edge, darkening about a metre out. The rocky green bluff dominates the right half of the picture. Blue sky with faint feathery white clouds. Makes me think of the song "Sitting on the Dock of the Bay."

The Bluebottle / Pacific man o' war (Physalia physalis), is a fascinating group of animals, hanging beneath the large, gas-filled structure called the pneumatophore.

Stay away.
