"The Detective of Northern Oddities"

"When a creature mysteriously turns up dead in Alaska—be it a sea otter, polar bear, or humpback whale—veterinary pathologist Kathy Burek gets the call. Her necropsies reveal cause of death and causes for concern as climate change frees up new pathogens and other dangers in a vast, thawing north."

"When they captured her off Cohen Island in the summer of 2007, she weighed 58 pounds and was the size of a collie. The growth rings in a tooth they pulled revealed her age—eight years, a mature female sea otter.

They anesthetized her and placed tags on her flippers. They assigned her a number: LCI013, or 13 for short. They installed a transmitter in her belly and gave her a VHF radio frequency: 165.155 megahertz. Then they released her. The otter was now, in ­effect, her own small-wattage Alaskan ­radio station. If you had the right kind of ­antenna and a receiver, you could launch a skiff into Kachemak Bay, lift the antenna, and hunt the air for the music of her existence: an ­occasional ping in high C that was both solitary and reassuring amid the static of the wide world.

Otter 13, they soon learned, preferred the sheltered waters on the south side of Kachemak Bay. In Kasitsna Bay and Jakolof Bay, she whelped pups and clutched clams in her strong paws. She chewed off her tags. Some days, if you stood on the sand in Homer, you could glimpse her just beyond Bishop’s Beach, her head as slick as a greaser’s ducktail, wrapped in the bull kelp with other ­females and their pups."
