Dive #853: REEF Survey on NOSC Tower
Jun 15th, 2009 by Michael Bear

Date: Sunday, 6-14-09

Location: Wreck Alley, NOSC  Tower

Time:  12:02 pm

Dive Length: 37 mins

Viz: 15 ft.

Max Depth: 61 ft

Mix: 31%

Temps:  68 F/61 F on bottom

Surface Conditions:  2-3 ft. swells and 15-20 knot winds w/whitcaps

Dive buddies:  Barb and NOAA Jim on hisscooter

Purpose: REEF Survey

Marine Life Observed:

Fish: Numerous Blacksmith, juvenile and adult, Surfperch, Blackeyed Gobies, Painted Greenlings, Opaleye, Sheephead, male and female, but more female, Senoritas

Invertebrates: Strawberry Anemones, Golden Gorgonians, numerous Giant Spined Sea Stars, Moon Sponge, Rock Scallops, Stalked Tunicates, Pterygophera californicus [Northern Sea  Palm], Macrocystis

Remarks:

After  a bit of dithering on Sunday and one cancelation, we got  a late start and decided to head out to the NOSC Tower in Wreck Alley for a REEF Survey and take some video. It was really ended up being  3 solo dives, all occurring at the time in the same general vicinity.
We had some swells and a good, stiff 15 knot wind, which picked up as the afternoon wore on, making for a choppy ride out and a great  day for sailboats.

We tied up to the Tower and it was then that I discovered that  I had a short fill on my tank, missing 600 lbs., so I knew this wasn’t going to be a long dive.

Nonetheless,  despite the surface conditions,  viz was a respectable 15 ft. once we got on the bottom and I ended up with a productive REEF Survey, including the fish and invertebrates you see listed above.

The only  invert I couldn’t ID was some sort of sponge I have only seen on the Tower and it looks like an oblong shaped, soft pancake, about 4-8 inches long, attached by a short stem to various hard objects in the area.

Need less to say, I surfaced first, to find the Scuba Do dancing on 3 ft swells, and our boat surrounded by at least 25 colorful sailboats, all enjoying the stiff, 15 knot wind……some of them not exactly under expert control and several of them veered  scarily close to the boat, but no mishaps occurred.
Dive safe, everyone……

New Study: Beaked Whales Can Get ‘Bent’
Jun 12th, 2009 by Michael Bear

A new study offers evidence to support the theory that beaked whales get the bends when they surface rapidly, possibly after being startled by naval sonar.

The report could help scientists understand why beaked whales appear to be more vulnerable to the potentially harmful effects of sonar than other marine mammals.

The Amazing ‘Arm’ of the Submersible ‘Nereus’
Jun 11th, 2009 by Michael Bear

To perform tasks in the deepest depths, engineers had to design a one-of-a-kind manipulator arm for the new depth submergence vehicle Nereus.
Matt Heintz is a research engineer in the Deep Submergence Lab at Woods Hole Oceanographic Institution (WHOI). He started his career at WHOI as a pilot for the human-occupied submersible Alvin. In 1999, he began developing the second iteration of the remotely operated vehicle Jason. Both of those vehicles use manipulator arms to collect samples and measurements on the seafloor. Heintz was responsible for developing a hydraulic power unit, sampling apparatus, and a manipulator arm with “good kinematics,” or ranges of motion, for WHOI’s newest deep-sea vehicle Nereus.

Dive #851: Mating Octos and a Giant Bat Ray……
Jun 11th, 2009 by Michael Bear

Date: 6/10/09

Dive Location: Vallecitos St., La Jolla Shores

Dive Site: Zion

Time: 7:30-ish [haven’t downloaded data yet]

Dive Length: +/- 45 mins

Max Depth: 91 ft.

Mix: 30%

Buddy: Prof. Charles

Temps: sorry, forgot to look….

Viz: quite good below 60 ft: +/- 20 ft., 5-8 ft. in shallows

Marine Life Observed: Mating octos, Sea Pens, Brittle Stars, Swimming Crabs, one very large Bat Ray, several large Sea Hares, several Sea Lemon Dorids, numerous Black-eyed Gobies……

Remarks:

As Jackie remarked, the Big Group met at V-St. last night, then broke up into smaller groups. I had not dived with Prof. Charles in a while and was delighted to have the opportunity to do so last night.

He and I and Navy Dan and his buddy, Erwin, kicked out until the end of the pier lined up with the pink house and dropped.

The idea was to try and hit Zion and move North from there.

I am delighted to report that we appeared to have landed directly on Zion at around 90 ft. and paused here for a while to watch the Black-eyed Gobies dart in and out of their little holes, here in the soft sandstone formations.

As much as I would like to take credit for finding Zion, I can’t. It’s always a crapshoot.

You either drop on it, or you don’t. However, at least now we know it’s just South of Vallecitos Pt at 90 ft.

From here, we moseyed along Northward until we came to the wall at Vallecitos Pt.,

Here, we made an interesting observation: if you come here after the sun goes down, the Brittle Star are all pretty much hidden, with only their arms waving in the current.

However, because we had dropped down well before the sun had set, we found many of the Brittle Star were still out, and you could see their bodies as well as their arms.

I had never noticed this in 8 years of diving V-St.

Moving Northward, along V-Pt., we came across what appeared to be a huge octopus, the size of a basketball.

I gestured for Prof. Charles and the other two dive buddies to come over to see it.

As we all gathered round, and shone our lights on it, the octopus divided in half and separated out into two octos.

We had stumbled across two octopi mating…..

They were understandably not happy with us interrupting their little romantic moment and the female most certainly did not like our lights and began to uncouple and move away.

Touchingly, the male reached out to her with a really long tentacle to try and pull her back, as if to say: “Aw, honey…….don’t let the humans bother you: come back!”

But, she was definitely not happy with our lights and scooted over into some debris to hide, leaving our poor friend feeling a bit frustrated and mightily annoyed with us, I imagine. Sorry, dude!

We left them to ‘get a room’ and moved on into the shallows.

While cruising along in about 20 ft. of water, I came across a site I always dread: a very large stinger, at least two feet long, laying in the sand about 2 ft in front of me—and, I was still moving forward.

I immediately applied the underwater brakes and you could almost hear them screech as I pulled myself to a halt.

Big Boy didn’t hang around to let us collide and before we could, he unfurled his huge wings and majestically took of, just a few feet in front of us. Whew!

From here, it was just a short swim into the 2 ft. surf and we were done for the evening.

Upon reaching our vehicles to unsuit, we all got to drool over some cool video that Penny and Jackie had shot of a huge Halibut, the size of Rhode Island and a Bat Ray taking off……..

‘Nuther day in Paradise, folks!

Dive safe, everyone…….
