How About Some Real Marine Science this Time - Science

Exploration of the deep brings us one mystery after the other and the delight scientists take in studying it is a marvel.  The video begins with two scientists who bring exceptional determination to understanding the most primitive worm there ever was.

Maybe you dismiss their study as valueless but these worms do not need light to survive and they get all their requirements from symbiotic relationship with multiple species of bacteria.

Ed:  so what?

Visualize a robo using that biological system for power, mate.

Ed:  did they say that?

No but part of the intrigue for them in their science is seeing what other scientists do with it.  Get cracking on that.

Note:  adding '- Science' to the title is redundant but that text can work as a search key for finding any articles of that nature in Ithaka.





Ed:  why don't you do that?

No way.  I'd be screaming for my ol' Mother as soon as the water closed over that bubble.  I like being underwater but doing it inside some kind of machine is not going to happen.


Here's another reason to go down there since just about everything makes its own light.  (Science Daily:  Three quarters of deep-sea animals make their own light)

It seems our lights mean we miss most of the show down there.


This is not some gee whiz observation since the researchers compiled a great deal of data.

The researchers compiled data on every animal larger than one centimeter that appeared in video from 240 dives by MBARI's remotely operated vehicles (ROVs) in and around Monterey Canyon. They counted over 350,000 individual animals, each of which had been identified by MBARI video technicians using a vast database known as the Video Annotation and Reference System (VARS). The VARS database contains over five million observations of deep-sea animals, and has been used as a source of data for more than 360 research papers.
