Patrick Webster is a marine media monkey politely pushing pixels as an underwater photographer and science communicator based out of Monterey Bay, California. After successfully sliming his way through marine biology and scientific diving classes as a UC Santa Cruz SCUBA Slug, Pat went on to work for the Monterey Bay Aquarium to spread the word about the colorful critters tucked away in his kelpy backyard. But once clocked out from the exhibit hall and often under the cover darkness, his alter ego @underwaterpat would venture out beneath the waves in search of salacious sea slugs to refill his opisthobank and feed the ravenous few his yearly “Tasteful Nudes” nudibranch calendar. His favorite nudie is Limacia cockerelli, which is always in May for his birthday. May the world know the wonders of the super slugs!

Tiare is an underwater photographer/videographer, commercial diver and marine debris artist from Vancouver Island Canada. As a self-described “Professional Fish Enthusiast” Tiare loves all things cold water and marine. She completed her Masters in marine resource science in Iceland and has worked in the dive industry on liveaboards in Alaska, BC and Mexico and as well as a dive guide at God’s Pocket for the last decade. Working as a freelance photographer, Tiare uses her images as inspiration for the underwater scenes she paints on her recycled marine debris art, capturing everything from nudibranchs to cetaceans. By turning plastic ocean pollution into art, Tiare hopes her work makes people consider what they put in and take out of the ocean so that nudibranchs (and other sea life) can live their best lives, frolicking in clean, plastic-free waters.
