Japanese Tsunami Debris: What Beachgoers Need to Know

Will you be heading to the beaches of North America’s West Coast this year? Beachcombing is one of the greatest pleasures for seashore enthusiasts, and the West Coast is well known for delighting us with a bounty of beautiful beach treasures! From driftwood to Giant Rock Scallops and sand dollars to polished agates, Mother Nature uses time, tides, and currents to provide us with the most fascinating finds.
Beachcombers in Hawaii, and from California to Alaska, might also expect to find an increased amount of ocean debris washed onto beaches over the next few years. According to NOAA (National Oceanic and Atmospheric Administration), due to the massive 9.0 Japanese earthquake and devastating tsunami of March, 2011, tsunami caused marine debris is already arriving on our Pacific shores. (Check out NOAA’s Tsunami Debris Sighting map.)
NOAA is leading efforts with federal, state, and local partners to collect data, assess the debris, and reduce possible impacts to our natural resources and coastal communities.
There is no reason to avoid beaches. Radiation experts believe it is highly unlikely any debris is radioactive, and the debris is not in a mass. Beachgoers may notice an increase in debris near-shore or on the coast, adding to the marine debris that washes up every day. The public should continue to visit and enjoy our coasts—and help keep them clean.

Very good information for all of us! But what to do if there’s an especially darling seashell among the debris?? That might be a moral dilemma (haha)

Right you are! Thankfully, the seashells found on the beach should be domestic.
