Into the Sandy Sea Floor with a Vital Forage Fish

Into the Sandy Sea Floor with a Vital Forage Fish

“Well-aerated, well-sorted, medium-to coarse-grain...” might sound like a wine flavor profile, but it actually describes the type of sandy, sea floor habitat preferred by Pacific sand lance. Sand lance play a crucial role in the Salish Sea’s food web, providing nutrition for everything from seabirds to whales, salmon, and lingcod. It’s thought that one sand wave field in the San Juan Archipelago alone could be home to over 12 million sand lance, but we’re only beginning to learn about their habitat.

Going Deep to Study the Small But Vital Sand Lance

How do you conduct research on tiny, elusive fish that live hundreds of feet below the surface, burrow under the sandy seafloor, and are only half the size of a dollar bill? Like any challenge in marine biology, when there’s a will, there’s a wave.

In 2018, SeaDoc and Ocean Gate worked together to bring a submersible to the San Juan Islands for researchers needing such a platform for their work. A team of scientists from the Alaska Fisheries Science Center, University of Washington, Moss Landing Laboratories, and Tombolo Mapping Laboratory was awarded sub time to study a very important forage fish.
