From a veteran water polo coach to an advocate for the protection of sharks, the passengers aboard the ill-fated Conception dive boat were linked by their love for the water. Santa Barbara County Sheriff Bill Brown told CBS News it appears the 34 people died of smoke inhalation before the fire reached their sleeping quarters.

Investigators are also looking into whether the crew was asleep when the fire started. The boat is required to have a roaming night watchman.

A team of fire specialists with the Bureau of Alcohol, Tobacco, Firearms and Explosives is now part of the investigation.

Before Justin Dignam founded a payroll company, he coached water polo at universities.

Dignam was a veteran water polo player, who played at University of Richmond before coaching a team at Iona College and becoming the head coach of Wesleyan University's men's team, according to Team USA Water Polo. He also served as a referee.

Big Fish Employer Services President Jeff Hill called Dignam a "fearless" CEO in a letter posted to the company's website. Hill said he was heartbroken but promised to carry on in leading the company to honor what Dignam started when he founded it in 2003 in Placentia, California.

"With dedication in the face of any adversity, we will carry on as the capable team that Justin relied upon, just as he would expect," Hill wrote.

Dignam is from Anaheim Hills, California and is survived by a wife and two children.

The girls volunteered together at the Santa Cruz County Animal Shelter, as did Adamic, who was "was an ally to all living things - orphan kittens, wild birds, youth volunteers - and a champion for the natural world around us," Jen Walker, a former humane educator at the animal shelter posted on the shelter's Facebook page.

Walker called Tia "an amazing young woman, filled with shy grace and the purest enthusiasm." She said she helped foster kittens, among other things, and her friend Berenice "was a model of gentle support for the animals and children she worked with at the shelter."

Apple colleague Dan Garcia, 46, joined them with his girlfriend Yulia Krashennaya, 40.

Krashennaya was a product manager at Spiralinks where she did contracting work for Cisco Global Event Marketing, Richard Stehn, a company spokesperson told The Mercury News.

The pair were avid divers and underwater photographers who went on trips around the world, the paper reported.

An Apple senior vice president Deirdre O'Brien said Garcia "was as passionate about his job at Apple as he was about his love of diving. Both leave many friends behind and will be deeply missed."

His aunt posted on her Facebook page that he had also worked for Amazon and called him a "gifted engineer" and a "talented artist in many venues."

"Dan was an incredible, special young man, 46 years young," his aunt Blanche Garcia wrote.

Salika met Adamic at Apple. Adamic later left the company, but Salika remained for 30 years, touching so many people with his "energy and enthusiasm," O'Brien said in a statement.

Allie Kurtz, 26, was the sole crewmember who died aboard the Conception.

She previously worked in the movie industry. But she left a job and life in Santa Monica earlier this year to move to Santa Barbara and follow her dream of working on a boat, family members said.

Kurtz worked as a cook on another boat for Truth Aquatics and was recently thrilled to be promoted as a deckhand on the Conception.

Kurtz, who grew up in Illinois, was free-spirited, well-traveled and studied theater and opera.

Her 71-year-old grandmother, Doris Lapporte, said she always loved the water and used to kid that she wanted to be a pirate someday. Her father, Robert Kurtz, and sister Olivia, 20, joked that she had fins and gills. They said they plan to scatter her ashes at sea.

"She left this world doing something she absolutely loved. This was her dream, and she was finally able to fulfill this dream," her sister said.

Adrian Dahood-Fritz and Andrew Fritz CBS News

Adrian Dahood-Fritz, 40, and her 40-year-old husband, professional photographer Andrew Fritz, had just moved to California from Texas for Dahood-Fritz's new job as a senior environmental scientist for California's Ocean Protection Council under the California Natural Resources Agency.

Dahood-Fritz led efforts to manage the state's network of marine protected areas and cared deeply about the ocean, California Governor Gavin Newsom said in a statement Thursday. She had done research in Antarctica.

"She embodied marine conservation and was a highly accomplished and respected scientific researcher," Newsom said.

The couple previously lived in Taylor, Texas, where they were known for their photography skills and volunteer work with animals.

Friend Josh Baker said he grew up with Fritz, and the two started a photography business in 2015. Fritz did portraits, weddings and other events. He also shot nature photography, mostly to fulfill his own passion, he said on his photography website.

In May, Fritz wrote in his website's blog that he was so enamored at seeing a Cheetah run at the San Diego Safari Park he had to put down his camera and watch with his own eyes.

Baker said Fritz was supposed to fly back to Austin in a few weeks to teach a photography class in which he was known for taking students to the Texas' Hill Country to shoot the night sky.

"He would teach classes, and they would be sold out for months," Baker told the Austin American-Statesman.

Baker said he and Fritz also formed a photography club called the North Austin Pfotographic Society.

Fritz had traveled the world scuba diving.

Marine biologist who joked her blood was salty

Kristy Finstad CBS News

Marine biologist Kristy Finstad joked that her blood was salty in a post on her scuba diving company's website.

She first put on a dive tank at the age of nine and had done hundreds of dives in the rugged, wind-swept Channel Islands, off Santa Barbara's coast, before leading the tour over Labor Day weekend.

The 41-year-old Finstad first swam in the national park as a toddler under her father's arm, according to the company's website.

She took over Worldwide Diving Adventures started by her mother in the 1970s and co-owned the company with her husband, also an avid diver.

Finstad studied damselfish and corals in the Tahitian Islands, dove for black pearls in the French Polynesian Tuamotus Islands and counted salmonids for the city of Santa Cruz, where she lived. She also did research for the Australian Institute of Marine Science and wrote a restoration guidebook for the California Coastal Commission.

"My mission is to inspire appreciation for our underwater world," she wrote on her company's website.

She and her husband had just returned from sailing across the South Pacific. It was part of their 10-year plan that started on the back of a napkin in 2006.

They left from the Channel Islands in 2015 on the journey and planned to return in 2018. Before they set off, Finstad wrote: "Our new boss is King Neptune: when it blows we hunker down; when there's surf we paddle in; when there's rain we wash up. In terms of time-lines, the best we can do is point in the right direction."
