Ocean Biolumination and the Aurora Borealis

Although late April in Alaska typically spells the end of the “dark days” of winter and hence the aurora borealis, we were fortunate to have an active aurora forecast (KP6) and clear skies on April 23rd. Perhaps the fates were aligning without my knowing it as spring in Southeast Alaska is known for its clouds and rain, but as  I drove out to The Cannery at Icy Strait Point I was greeted by stars and a moonless night.  From the parking lot my feet crunched on the gravel of the rocky beach. I walked along with the water lapping near my feet and the sea-air filled my nostrils from the swelling waters of a high tide. I was not alone out there. My headlamp lit up only a small portion of the inky-dark night, but up ahead a mink’s eyes showed brightly like two opals in the dark. Another mustelid, a River Otter, swam in the waters just offshore. He got closer to me several times, obviously trying to figure out what I was up to. All of these wonders were the precursor to the amazing show that was only be beginning.

At 12:30 AM The aurora began to intensify over the waters of Port Frederick. Soon the pulsing green, pink, and white lights turned the ocean fluorescent green and my eyes wide. I had never seen a display this active in Southeast! I worked with my camera to tether together the sea and the Northern Lights. I was fortunate enough to have the Alaska Marine Highway Ferry add some scale at about 1AM.

At 1:30 AM the adrenaline of the incredible show finally started to wear off. I set off down the shore to go home,  staring at my feet to avoid tripping. That’s when the first small blue light in the water caught my eye. I splashed a rock into the water and blue waves of biolumintation echoed out from its crater. I stepped into the water, and my footprints erupted with light. All around me in the waters of Port Frederick, small, bio-luminescent creatures swarmed and let off burst of cerulean blue light like underwater fireflies at the slightest disturbance. It was then that I knew what I had to do! My camera began clicking 6 inches from the water’s surface as I sought together bond together the lights of the sea and the lights of the sky as its unlikely I will ever have this unique experience ever again!
