“For heaven’s sake, when you see the enemy attacking, you pick up the pitchfork, and you enlist everybody you see.”

They have a lateral line down their whole body that senses motion, but maybe it does more than that.

The Arctic is an ocean. The southern pole is a continent surrounded by ocean. The North Pole is an ocean, or northern waters. It’s an ocean surrounded by land, basically.

Everyone has power. But it doesn’t help if you don’t use it.

Like a shipwreck or a jetty, almost anything that forms a structure in the ocean, whether it is natural or artificial over time, collects life.

In terms of personal choices, let’s all think more carefully about where we get our protein from.

The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents.

I have come up at the end of a dive, and the boat was not where I left it. I had to take care of a buddy who did panic. But I was confident the boat would come back.

Humans are the only creatures with the ability to dive deep in the sea, fly high in the sky, send instant messages around the globe, reflect on the past, assess the present and imagine the future.

If somebody dumps something noxious in my back yard, the dumper is the last one I would call on to repair the damage.

We have become frighteningly effective at altering nature.

Nothing has prepared sharks, squid, krill and other sea creatures for industrial-scale extraction that destroys entire ecosystems while targeting a few species.

I actually love diving at night; you see a lot of fish then that you don’t see in the daytime.

The best scientists and explorers have the attributes of kids! They ask question and have a sense of wonder.

I love music of all kinds, but there’s no greater music than the sound of my grandchildren laughing; my kids, too.

Just as we have the power to harm the ocean, we have the power to put in place policies and modify our own behavior in ways that would be an insurance policy for the future of the sea, for the creatures there, and for us, protecting special critical areas in the ocean.
