Selected Works

Talk To Me
Dolphins communicate with each other, but can they communicate with us? Marine biologist Denise Herzing is drawing on decades of research, a vast digital library of whistles and clicks, and new computer wizardry designed to bridge the species gap.

July 2011
Blood In The Water
On December, 24, 2009, a 6,600-pound orca killed trainer Alexis Martínez at a marine park in the Canary Islands. Two months later, trainer Dawn Brancheau was killed by an orca at SeaWorld Orlando. Should Martínez’s death have served as a warning about the lethal potential of killer whales being trained for our entertainment?

February 2011
The Long Way Back
After Marine Corps Veteran Ronnie Simpson survived an explosion in Iraq in 2004, he threw himself at an audacious goal: to sail around the world. It almost killed him.

July 2010
The Killer in the Pool
Last February, when a 12,000-pound orca named Tilikum dragged his SeaWorld trainer into the pool and drowned her, it was the third time the big killer whale had been involved in a death. Many observers wondered why the animal was still working. But some experts, knowing the psychological toll of a life spent in captivity, have posed a darker question: Was it human error, or can a killer whale choose to kill?

February 2008
Hell in High Water

In January 1969, six boys hiked into California’s Sespe wilderness for a camping trip. None came back alive. Thirty-nine years later, Tim Zimmermann examines how one wrong decision in the wild can change the course of history.

It’s Hard Out Here for A Shrimp
What swims at 20 miles per hour, can carve out hunks of human flesh, and will attack anything that moves? The Humboldt squid. Brace yourself for a dive with the eeriest beast in the ocean.

On Top of the World
Knocking off adventure firsts is nothing to scoff at. But David de Rothschild plans to use his far-flung expeditions for something else entirely.

August 2005
Raising the Dead
At the bottom of the biggest underwater cave in the world, diving deeper than almost anyone had ever gone, Dave Shaw found the body of a young man who had disappeared ten years earlier. What happened after Shaw promised to go back is nearly unbelievable—unless you believe in ghosts.

You better grab a lifeline and hold on tight when Steve Fossett decides to make another manic bid for glory

    Hi, my name is Heather, I have an assignment coming up for my composition class, the assignment says :In this paper you will respond to an article or essay on a topic of interest to you and use examples from your own life to support your arguement either agreeing or disagreeing with the essay’s claim. I wanted to write my essay in response to “Killer in the Pool”, I think it is a great and informative article that I have recomended to all my friends to read. I am in college earning my degree in marine biology so this is a topic that is important to me. I waas just wondering if you would object to me writing my essay as a response to your article? I would be more than willing to forward you a copy of my finished paper if you wanted. Thank you.

    *I will be agreeing by the way

    You are my biggest inspiration, i’m 16 years old and after i watched the documentary “Blackfish” I was astounded. My life had changed and my viewpoint of not only SeaWorld but just orcas. You are the best thing that has happened to SeaWorld in a very long time. Your work is fantastic, I have researched and researched for any way for you to see this. Tilikum has spent almost his whole life in captivity and its time for a change, you are the biggest inspiration to a lot of people, and I thank you Tim Zimmermann for the work you’ve done.

      Best, Tim
