      Hope Spots hold no specific policy weight—the designation is meant to draw attention to culturally, ecologically, or economically important places.

      “Nearly 180 kilometers off the coast of San Diego, California, there’s a surf break that, from time to time, spawns waves rising taller than two telephone poles stacked on top of each other. They inspire awe—and caution—in those driving the boats carrying big-wave surfers in search of the next world record. Yet there’s another hazard lurking in these waters: Bishop Rock, the summit of an enormous underwater mountain, lies just a meter or two below the surface. When the sea is particularly rough, Bishop Rock can poke its head through the troughs of larger swells.

      Bishop Rock is the peak of one of 60 underwater mountains—or seamounts—off the coast of California that rise more than a kilometer from the seafloor. Last month Mission Blue, a conservation organization founded by famed oceanographer Sylvia Earle, designated all of these seamounts as Hope Spots. Hope Spots are areas critical to the health of the ocean for any number of reasons: an abundance or diversity of species, a unique habitat or ecosystem, or significant cultural or economic value to a community, to name a few.

      Like much of the dark expanse of the deep sea, so little is known about seamounts that scientists aren’t even certain just how many there are in the world. Current estimates from the US National Oceanic and Atmospheric Administration put the number around 100,000—30,000 of which are in the Pacific Ocean. One thing scientists do know about seamounts is that they’re hotspots of biodiversity: places where fish gather to spawn, marine mammals congregate to feed, and precious minerals slowly accumulate over the course of millions of years. This makes seamounts attractive for more than just big wave surfers—fishermen have long known that their bounteous waters attract commercially profitable species such as tuna, rockfish, swordfish, and sea bass. In recent years, seamounts have also become destinations for mining companies exploring the sea in search of precious metals including cobalt, copper, manganese, and gold, for which demand has increased with the advent of consumer electronics and the batteries used for solar panels and electric vehicles.”
