PUBLISHER’S NOTE<br />

WHAT I LEARNED<br />

FROM OUR<br />

COVER TEST<br />

Text by Stephen Frink<br />

Photos by Brandon Cole<br />

O<br />

ccasionally we simply can’t decide<br />

what photo should appear on<br />

the cover of Alert Diver. We are<br />

fortunate that so many of the world’s<br />

most talented marine photographers<br />

regularly share their vision with<br />

our readers, but this can make for difficult choices.<br />

Sometimes to resolve the question we reach out to our<br />

members to help us decide by means of an online cover<br />

test. Humpback or orca, we wondered. As you will have<br />

seen, Brandon Cole’s humpback photo prevailed.<br />

Sometimes the decision is about more than just<br />

aesthetics. When I posted the cover test on my own<br />

Facebook page, I had several friends who explained<br />

their vote for the orca with environmental reasoning.<br />

Susan Eaton commented: “Orca, hands down…. The<br />

orcas of Vancouver Island are endangered, so this<br />

choice will serve to highlight this issue.” This was<br />

news to me. I’m not surprised, I suppose, but because I<br />

usually work in tropical waters I’ve been more engaged<br />

with issues such as coral bleaching, ocean acidification<br />

and shark finning. Working from the<br />

premise that you have to know an<br />

animal to photograph it consistently<br />

well, I asked Brandon Cole: “What’s<br />

going on with the orcas, and should<br />

we be worried for them?” His reply:<br />

seen in the waters around southern Vancouver Island<br />

and in Washington’s San Juan Islands and Puget<br />

Sound) now must spend more time and energy ranging<br />

widely for the salmon.<br />

There’s also the problem of marine pollution.<br />

Industry and millions of people in the greater<br />

Vancouver and Seattle metropolitan areas have left<br />

a legacy that can’t be easily cleaned overnight. Apex<br />

predators at the top of the food chain — orcas — are<br />

highly susceptible to accumulation of toxins (e.g.,<br />

heavy metals and PCBs [polychlorinated biphenyls]) in<br />

their tissues. Such toxic exposure places considerable,<br />

continuous strain on the whales’ health, which in turn<br />

affects the next generation.<br />

As if these formidable challenges weren’t enough, the<br />

orcas also must contend with very busy, noisy waters. The<br />

surface presence and emissions of so many watercraft and<br />

the underwater noise generated by their engines further<br />

alter orca behavior and affect orca health.<br />

I had not expected such unfortunate news. I originally<br />

saw this image as celebratory: a killer whale leaping<br />

from the sea for the sheer joy of it — a “Willy,” wild<br />

and free. But, of course, the backstory of any marine<br />

photograph is as important as the first impression,<br />

maybe more so, and I’m glad to know more about that<br />

one. It makes me think about what I might do to help.<br />

Choosing to not compete with the orcas for food is<br />

one option. I could make a conscious choice to avoid<br />

wild-caught salmon, particularly Chinook. Of course,<br />

it may not even be possible to accurately sleuth out<br />

where a salmon has come from by the time it gets<br />

to the grocery store or restaurant, but elevating the<br />

choice to a conscious consideration is a step in the<br />

right direction.<br />

I am worried, absolutely. I’ve been<br />

following these pods of orcas for<br />

decades, and there’s no doubt that<br />

they have been, and still are, facing<br />

strong headwinds, primarily of<br />

our making. We’ve overfished their<br />

main food source, Chinook salmon.<br />
