Shark Stories

A few interesting stories on shark attacks and near misses on the Shark Shield report so I thought I would start this thread. Don't want to trivialize the subject as people have had their lives taken or changed forever by what can happen. I thought it might serve as an educational purpose by hearing others experiences so we may all learn from them and hopefully avoid it happening to us.

One of them was a mate of mine named Hazey.
He had been surfing at Castles, a notoriously sharky wave in the bay at Cactus.
Several hundred metres offshore the wave breaks before reforming into Inside Castles making a long left with several sections. The wave has been the scene of several attacks and near misses over the years including the local known as "Sharkbait" who had been attacked more than once.
Gerry Lopez is another who came very close to being attacked out there and vowed to never surf Cactus again after his near miss.
Well Hazey was surfing out the back with another bloke named Steve when out of the blue he was launched into the air still on his board by a huge force from below.
A shark had rammed him with a direct hit straight up into the air! In a moment it was gone but soon returned to the stunned Hazey and started biting him and his board. Hazey instinctively put his arms out to protect himself but both his arms ended up in its mouth. As the jaws closed down his arms could have easily been severed, but several teeth on the sharks lower jaw had become dislodged and imbedded in the board leaving his upper arms with massive injuries, but the vital inner arms where major arteries run were not majorly damaged. This probably saved his life.
By this time Steve had reacted and in a rush of adrenalin and pure ballsy courage he threw himself onto the sharks back and started gouging at the sharks eyeballs, eventually feeling one pop and the shark departed.
Steve got the two surfboards together and got himself and Hazey on and started the long paddle to shore.
Then they were both thrown into the air as the shark rammed them a third time before disappearing again. They continued to make their way closer to shore and the shark nudged them again. Steve told me he thought he really must of pissed it off when he popped its eye.
Finally they we're just a metre from shore when the shark made its fifth and final appearance. It beelined towards them and the shore while they stood in waist deep water with their boards. The sharks mouth was just rapidly opening and closing like one of those wind up sets of false teeth. The boys separated and put their hands on either side of it's body and held it on a 90 degree angle to the beach as they made the final steps to the safety of the sand.
Hazey was rushed to Ceduna hospital and then flown to Adelaide for micro surgery on his shredded arms.
Steve ended up receiving a bravery award and they both sold their story to 60 minutes and made $50,000 each out of it!
It was quite a story!

I paddled out at Waddy point on Fraser a few years ago alone. Right on sunset, side-shore, murky water, bait fish popping everywhere. I caught a shitty little wave paddled back out and sat. Just kinda taking in the sunset and emptiness, just my car alone on the sand and then this bone chilling shiver went through me, I can't describe it. Probably be silly to be out there to begin with but every fibre of my being said get the blazes out of there and fast.

I paddled in and belly rode a little wave into the shore.

I walked up to the car, dried off and drank a beer. Didn't see anything but knew somehow that at that moment I was on borrowed time.

I've had a couple of encounters in my surfing life but not seeing anything was the one that scared me the most and probably the only time i've ever paddled in.

because with winter morning sun that shark was very well hidden from view the whole time by the glare field......amazing how close they can get.

I watched a big white swim right up the line-up at the Point a few years ago, swam within 10 feet of about 30 people and no-one saw it because anyone facing that way would have only seen glare.

Only reason I saw mine so clearly was that I was surfing a point and it came south to north so I had the winter sun behind me = perfect view.

If it came the other way I would not have seen it.

Don’t think that predators approaching with the sun behind them is coincidence. It’s not.

I've always followed that advice ever since I read that article of Greenough's in SW a few years ago, running through 6 of his most memorable shark encounters on the mid north coast. He talks about engaging with a shark at Wategoes that repeatedly tried to move into the glare of the sun, and would retreat every time he spun to face it. Whenever I am out surfing I will always sporadically turn to face the glare of the sun, and if it's a sharky spot I pretty much always face that way.

I was crowd dodging this morning so I paddled out on a beach break where two others were surfing...... and they immediately went in. Surfed by myself for an hour until what I'm guessing was a bull shark surfaced a
4-5m away. Paddled, pretty briskly, onto the bank and caught one in.

An excerpt from 'Sharkbite Right' by Michael Kew. Inside Pohnpei's fringing reef, large motherships wait for pilot boats to return from fishing FSM waters, then unload the catch in their enormous holds and steam off the ports of South-East Asia.
 
Kew doesn't say whether Hamilton deliberately crashed into the Micro Glory. In another version of the same story, Hamilton claims he did it deliberately.
 
"Alan Hamilton moved from Palos Verdes to Santa Barbara in 1967, when he was 17. In 1971, a few months after a guy named Mort McIntosh had first surfed Pohnpei, Hamilton and partner John Bradbury became the first owners of a parcel (#55) in the Hollister Ranch, where the regular-footed Hamilton surfed exclusively. A diehard sailor, he became a commercial fisherman, skippering Alamo, an old shrimp boat based in Santa Barbara Harbor. In 1987 he hired an energetic Pohnpeian deckhand named Danny, who was in Santa Barbara illegally as an undocumented alien.
 
“After Pohnpei and those other islands got their independence in 1986,” Hamilton told me, “they hired this guy named Bill Bixler to go out and do a survey of the tuna. Bixler hired Danny, and when they were done surveying, they smuggled him back to Santa Barbara, and he started getting jobs on everybody’s boats.”
 
At Danny’s urging, Hamilton visited Pohnpei in early April 1991. He brought two surfboards with him and stayed at Danny’s house at the base of Sokehs Rock. “I got a map of Pohnpei and saw Palikir Pass on it,” Hamilton said. “I thought it looked like a good setup for surf. Danny was there with me, and he had a little boat, and I said, ‘Danny, take me out to this pass.’ We went out there, and it was just this dynamite wave.”
 
Palikir was offering glassy, head-high sets. It was Hamilton’s second day on Pohnpei; he stayed two months.
 
One night, Hamilton was in a smoky bar, shooting pool with FSM president Bailey Olter. Olter offered Hamilton the job of skippering the 80-foot Kocho, a Japanese fishing boat seized while fishing illegally in Pohnpeian waters. Skippering sounded good, and he knew boats, so in June 1991 Hamilton returned to Santa Barbara and sold everything he owned, including Alamo and the Hollister Ranch parcel, in less than two weeks, because on Pohnpei, a new life of deep sea-fishing and Palikir-tuberiding awaited.
 
Not all adhered to plan. Hamilton: “The senator who was in charge of the project was from Mokil Atoll, like 100 miles from Pohnpei, and he had a store out there. I ended up just taking all of these sacks of rice and cigarettes and everything out to the senator’s little store instead of going fishing, like I was supposed to. I was supposed to do all these fishing trips and stuff, but never did.”
 
Yet surfing was never far. Palikir was Hamilton’s main wave, but he surfed around the island, in all seasons. And he was always alone except the few times he took a visiting marine biologist out, or when he surfed Palikir with Mark Hepner, a Kauaian diver who exported tropical fish.
 
On April 9, 1994, Hamilton almost lost his left hand and forearm to an 8-foot-long bull shark. He was surfing at Palikir; it was a foot overhead and perfect, with nobody in sight. Around 2 p.m., he kicked out of wave, and started paddling back out. On his second stroke—BAM!
 
“The shark came up from behind me super fast and it was like a grenade went off in my arm. It was going in too fast; it bit and then it slid down my arm. The shark yanked me off my board and then went backwards off my arm with its jaw clamped down, scraping my flesh off down to my fingertips. It took all the tendons and it broke my bones—and I was way out there by myself at Palikir. My panga was parked on the reef, so I just caught a dinky wave with my one arm and glided on in to the boat. I was bleeding like crazy. The only chance I had was to get into town as quickly as I could.”
 
Hamilton’s boat had a paltry 9-horsepower outboard; the trip to Palikir from Kolonia took nearly 30 minutes, longer than most. He managed to start the motor, untie the anchor, and head back toward town, but immense blood loss caused Hamilton to drift in and out of consciousness.
 
“I went blind because all the blood went out of my head, so I laid down because I couldn’t see anymore. I figured that, hell, I was going to die, but when I was laying down, my vision came back, so I just stayed down and drove with my feet.
 
He crashed into the Micro Glory, a docked freighter that was about to depart for Kapingamarangi. The crew looked down, grabbed him, and rushed him to Pohnpei Hospital in Kolonia, where he remained for six days, receiving rudimentary but adequate care. He flew to Honolulu for further treatment at Tripler Army Medical Center, but the hospital would not accept him. So he rang Santa Barbara’s Cottage Hospital, which “couldn’t wait” to get him in.
 
“They treated me like I was Mick Jagger,” Hamilton said. Cottage sought to specialize in orthopedic surgery, and Hamilton was a prime guinea pig; the hospital treated “the sharkbite guy” for free, and over the next four months he had four operations. The fingers of Hamilton’s left hand no longer functioned but, permanently stuck in an outward closed formation, he could still paddle, and in February 1995 he started surfing again. Back on Pohnpei, his blood-stained surfboard was nailed to a wall in Rumors, a lively bar among the mangroves at Sokehs Harbor.
 
In late 1995 Hamilton bought a 30-foot fiberglass boat and sailed it from Hawaii to Tahiti, where he stayed three years, doing essentially nothing. Via Yvon Chouinard, a friend of Hamilton’s, Chuck Corbett heard of him and invited him to Kiribati. The two sailed to Fanning Island in separate boats. It was the summer of 1999; Hamilton stayed for 18 months, surfing Whaler Anchorage and English Harbor.
 
“He was 49 years old, smoking two packs a day, and surfing double-overhead waves alone,” Corbett said. “To this day, he is the most stylish surfer I have ever surfed with.”

Can't promise blood as this weekend's scary shark tale had a happy ending.
Weekend shark story hails from the land of the "Great White Whale surfer".

Message from your Minister:
"They did the right thing by choosing to wear a personal shark deterrent, which I'm sure assisted them in that circumstance."

PS: (Story reads 3 shark shields invite a sea of sharks to trap boys on a bommie!)
Jedd: Yeah! Outta nowhere this shark comes thru at 100 MPH & hit Emilio then 'almost' went straight for me...cause I had a big Sambo.

3 Shark Shields are meant to signal as a larger deterrent?
Shark zeroed in on 'empty handed' Emilio & hit him.
Then 'Almost' checked Jedd with the catch.
Mop top Ranga Toby never saw any underwater action.

Just to start they say the risk of white shark attack is greater in months of high rainfall and next to river mouths.
They also reference the latest severe attack on Jason Edward's at Belongil, who was lucky to escape with his life.
That was nowhere near a river mouth and during a record dry summer.

Try again.

Using the Byron-Ballina area as the focus of studies (smart) the chief researcher dropped this clanger: "Using historical data on sea surface temperatures, the researchers were able to establish that attacks were occurring in areas along the coast where the water was cooler, either compared with surrounding areas of water, or compared to the same site the year before or the year after the time of the attacks.

These pockets of cooler water are caused by upwelling events, where dense, cool, and nutrient-rich water gets forced up against the coast. Such areas of the ocean are highly productive and sharks may be attracted by the abundance of fish or other prey, such as seals, that might follow the fish"

Really? Seals?
They might be coming in to feed on seals, around Byron-Ballina?

Try again.

"What causes these cool upwellings, specifically on the Far North Coast of NSW where there has been a higher than normal rate of bites and attacks, is the strengthening of the warm East Australian Current, so what’s nice about that is potentially we can look at the climatic factors which affect ocean current movement, and so have a little bit of a warning ahead of time."

Really? The EAC causes upwellings?

Try again.

Love ya work, but just have to pull you up on that last point. Yes, it is true that the EAC does not cause upwelling but it certainly influences it via a phenomena called preconditioning where the isotherms are uplifted adjacent to the coast. See this paper for more detail (probably only need to read the intro):

Braudilio, from the intro: "It is well documented that wind stress and wind stress curl drive upwelling. When an along-shelf wind induces offshore surface transport, it leads to a divergence close to the coast that triggers the upwelling of cold nutrient-rich water originating from greater depths. The theoretical Ekman cross-shelf transport [Ekman, 1905] is now widely used as a proxy for upwelling [Bakun, 1973; Alvarez et al., 2008], while the dif- ference between the theoretical and the observed cross-shelf transport gives some insights into the spatial variability of the upwelling and the coastal divergence of Ekman transport [Kirincich et al., 2005; Dever
et al., 2006]."

To talk about upwelling events, especially inshore and especially sustained ones without mentioning Ekman transport (as the paper you referenced does) seems very short-sighted.

Sure, the EAC might "pre-condition" the isotherms but it's the Ekman transport which does the heavy lifting.

It's the continued N'ly winds which are driving the summer upwellings, not the EAC itself.

Wouldn’t warmer water from the EAC contribute to stronger / more frequent NE convection winds and thus more upwellings ?

Asking , not stating .

Warmer water in the EAC would mean less difference between land and sea during diurnal heating, and less strength to the NE'ly and upwelling. Also a deeper mixed layer so it'd take longer to upwell the colder water I'd believe.

Wasn't in any way defending the UMac article freeride. Agree the quote from the article is very short-sighted, and misleading, in attributing upwelling solely to the EAC. Sounds like something regurgitated from what someone else told them.

I just wanted to point out that the EAC plays a major part in upwelling events on the Nth NSW coast. It's definitely the sustained N wind that drives it but depending on EAC preconditioning then potentially less wind (in terms of duration and strength) will cause greater upwelling. i.e. from deeper water. And vice versa of course.

nup. convection winds are E through SE .

warm waters inshore from EAC means less temp differential between land and sea and leads to much less strong sea breezes.

One of the main negative feedback loops happening through summer now, is weak mobile high pressure which brings Northerly episodes. These drive upwellings, with the cooler inshore water bringing increased temp differentials and stronger N'lies.

That is one of the chief drivers of lack of moisture. The cooler N'ly winds hold much less moisture compared to warm, moist E through SE'lies.
In effect, they are desert winds.

It's these moist Tradewinds which have been flukey and lacking over summers in the last 5-7 years.

edit: basically, what Craig said.

Yep and as Braud has pointed out the EAC would play a part. I think I read that also where it seperates from the East Coast proper around Seal Rocks it can cause upwelling, especially when spawning eddys etc.

yeah, in that paper they reference an upstream and downstream segment with large scale eddies between them.

My theory is the greater contributor to increased summer North Coast upwelling is the Tasman sea heatwave.
By having warm rising air in the lower Tasman, normal summer highs are weaker and more mobile and hence we are getting less Tradewinds and more N'ly episodes.
Which is increasing Ekman transport and giving more upwelling.

But I can't find any papers to back that up.

Saw a seal recuperating on the rocks at south wall Ballina a few years ago from bite marks around its back , this time of year .

yep, they do get lost from time to time.

juvenile leopard seal was on the beach at Lennox this winter. Unfortunately, in poor condition and died.

Several years ago we would get one turn up here for a couple of weeks each year. Feed out on the bait grounds and laze on the rocks all on it's own. Always thought it was a bit strange to see them so far north but Nation Park rangers reckoned it was not so uncommon. Would make for interesting discussions in the local rag.

Freeride, I see your reasoning wrt to Tasman heatwave effects. Don't have time to dig for references at the moment. However,

https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2017GL073714
Talks about MHWs from a different perspective but 4th paragraph of intro touches on the contributing processes. Probably goes in to depth later on but I don't have the time to delve right now. One thing is for sure, the ocean/atmosphere feedback is one complicated and complex system.
