"What's this weird-looking thing I found on the beach?"
"How can I tell if it's safe to dig for clams?"
"Help! There's a baby seal on the beach, what should I do?"
Ever since we opened in 1965, people have turned to the Visitor Center when they have questions about the things they discover and experience on the Oregon Coast. Our marine educators and scientists often know the answers - or how to find them.
Submit your question - We'll ask one of our resident scientists and marine educators to answer selected questions, and we'll publish those answers here.
Here are some recent questions we've received, and the answers:
Q. What should I do if I find something on the beach that I suspect may have come from the tsunami that occurred in Japan last year?
A. The tsunami in Japan that occurred in March 2011 ejected massive amounts of debris into the Pacific Ocean. Some of the floating debris is expected to show up on beaches in North America. The first large piece of Japan Tsunami Marine Debris to arrive was a large dock that washed up in Newport in early June 2012.
The state of Oregon recently set up a telephone hotline where the public can ask questions about tsunami debris. Just dial 211. If you experience technical problems with the hotline, use the backup number: 1-800-SAFENET.
Marine debris items or significant accumulations potentially related to the tsunami can be reported to DisasterDebris@noaa.gov. For more information, visit the Japan Tsunami Marine Debris website, or download a flier.
The flier advises:
If you find something that you think might be tsunami debris, use common sense and follow general safety guidelines. If you don't know what an item is, don't touch it. If it appears hazardous, contact appropriate authorities.... It is important to remember that not all debris found on U.S. shorelines is from Japan, so please use your discretion when reporting items.
Q. My son and I love the Hatfield Marine Science Center and on one of our last visits, we were able to "pet" several of the fish in your shallowest touch pools. I could be crazy, but one of the fish actually seemed to move and bare more of his underside and it really seemed as if it enjoyed the touching and especially the belly rubs. Have you ever done any studies on interaction with the fish and does it seem likely that a fish could actually enjoy being touched? We never really considered that a fish could like being snuggled! - Megan W.
A. While our fish are very acclimated to visitor interaction, generally most fish don't positively respond to human touch. In fact, certain fish (such as salmon) are negatively affected by losing their protective mucus layer wherever they are touched. Studies have showed that when salmon are handled and then released, have a lower chance of survival due to stress and infections. (Our touch tank is populated with fish who can tolerate being touched, but even they need to be rotated out of the tank periodically to avoid becoming over-stressed).
Food is an important factor in human and fish interactions. I have seen schools of fish (sharks in the Bahamas and large reef fish in Australia) who approach divers to be touched because they have been been fed previously at that location. - Dr. Bill Hanshumaker, Visitor Center marine public education specialist.
Q. I was walking on the beach yesterday and came across hundreds of dead starfish .... I counted at least 20 to 30 star fish every 25 feet on the beach north of Driftwood Shores in Heceta Beach. It was very sad. Could you please explain? - Luna
A. There are a couple of possibilities. It was reported that these were pink (Pisaster brevispinus) sea stars, rather than common ochre sea stars. Ochre stars are typically found in rocky intertidal zones while the pink sea star is typically found on soft bottoms, sometimes extending out to deep water. It's possible that a local hypoxic zone formed and killed these sea stars, which were then brought to the shore by waves and currents.
For more information about hypoxia, visit the PISCO Web site.
Another possibility may be a localized kill cause by recent heavy rainstorms. If these occurred during low tide, the change of salinity in the tide pools might might have killed the local inhabitants. Other possibilities include a by-catch dump from a bottom trawler, or even a local disease breakout.
Q. How can I tell if there's a red tide on the beaches?
A. "Red tide" is the colloquial term for a naturally occurring "bloom" of marine algae, some of which are red. Red tides are of concern because they can signal an increase in toxins secreted by the algae. Since clams and other shellfish consume algae, harmful algal booms can make the shellfish unsafe to eat. The Oregon Department of Fish and Wildlife monitors Oregon's beaches for algal blooms and toxicity levels. When the level is high,the state may close affected beaches to harvesting of clams, mussels and other shellfish. Typically, this occurs during the summer months.
To find whether such a closure is in effect when you visit the Oregon coast, and whether it's safe to harvest and eat shellfish, call the state's Shellfish Safety Hotline at 503-986-4728 or 1-800-448-2474 toll free or on their website.
Q: We found a seal pup alone on a beach. It's mother didn't seem to be anywhere around, but there were a lot of people on the beach taking notice of the pup. What should we do?
A: The Oregon Marine Mammal Stranding Network (OMMSN) responds to reports of stranded or injured marine mammals on Oregon beaches, and is based at HMSC. From the OMMSN webpage: "In the spring, harbor seal pups are frequently found alone on the beach. They are usually not stranded, but simply resting (as all baby mammals must do) and waiting for their mothers to come back ashore to nurse them. Adult female seals are shy and a mother is unlikely to rejoin a pup if there is activity nearby. She may only return to suckle her pup at night when people are not around. It is very important not to interfere with this process, and especially not to move a pup from where it is receiving care from its mother. Within three or four weeks of birth, harbor seal pups are weaned from maternal care and are left to fend for themselves. While learning to find and catch its own food, a young seal may come ashore frequently to rest. This is often a very challenging stage of life, and not all pups survive. But while it may be tempting to “take them in,” their best chance for survival is to be left alone on the beach."
Sometimes the OMMSN will post signs to alert the public to the presence of a seal and encourage all to keep a respectful distance from the resting animal. If you are concerned about the welfare of a seal pup or any other marine mammal you encounter, report it to the 24-hour Oregon State Police hotline at 800-452-7888. Please describe the situation and location of the animal so the OMMSN can follow up on your concerns.
Q. I am a 5th grade teacher in the very early planning stages of a field trip to Newport. I am trying to hit the lowest tide which I believe is the Neap Tide in May 2010. I cannot find tide tables for that month. Would you be able to assist me in finding the lowest tide dates in April and May 2010 so that we can set dates for our field trip? - Kathy E.
A. NOAA tide predictions are issued year-by-year, and may not cover the period you're interested in. For dates farther into the future, try the online Tide and Current Predictor sponsored by the University of South Carolina. Choose the region you're interested in, then scroll down to find the specific coastal location for which you want tide predictions. Enter the appropriate date range (and whatever other information you have) into the predictor, and hit the "Make prediction using options button." Keep in mind that tide predictions are based on historical data; actual high- and low-tide levels can vary significantly due to a number of factors.
Q. Four or five years ago on a trip back to Oregon I saw a submersible on display in the HMSC that had a black, melted patch on the bottom. I remember being told or reading that it had contacted a hot lava flow and has some lava stuck to it. Am I remembering this correctly? Or was it melted by a hot spring? What is the name of the submersible and when did the encounter happen? I have searched the OSU and NOAA archives and can't find any mention of the incident, so I am beginning to think I dreamed this up! - Tom D.
A. We have a large underwater instrument package, called a Rumbleometer, on display here at HMSC. It is not an ROV (submersible), but an instrument platform for measuring changes on the ocean floor. In 1997 it was deployed on the Axial Volcano off the Oregon/Washington coast. The following year it was caught in an eruptive event and its legs were encased in molten lava. The "hardhats" which protect its glass floats were damaged by the heat, but the Rumbleometer was ultimately recovered by the Canadian ROV ROPOS (Remotely Operated Platform for Ocean Science).

Q. Hello, I was wondering if you could identify the animal in the attached photos.
I was walking on the beach south of Waldport, at Tillicum Beach on March 24, 2009, and this was washed up on shore. The total length was around 4' long. My first thought was an eel, but looking at photos, it doesn't seem to match. - Chuck W.
A. Marine educator Bill Hanshumaker identified this animal as a lancet fish, and notes that he received a report of a lancet fish stranding near Beverly Beach around the same time.
Lancet fish are large oceanic predators in the genus Alepisaurus ("Scaleless lizard"), the only living genus in the family Alepisauridae. They can grow up to 2 metres (6.6 feet)in length. Even though lancet fish are widely distributed in all the world's oceans (except the polar seas) very little is known about their biology.
Q. I recently moved to Oregon from the East coast and I'm ecstatic about being able to catch my own clams and crabs on the coast. When I've gone crabbing I go to the Newport public fishing pier by the Rogue brewery. I've noticed a dock off of that east end of your parking lot and see a sign that says official vehicles only, but nothing about people. As you've guessed by now I'm curious if I can crab off of that dock.- Troy A.
A. The pier is where Oregon State University's research vessels, as well as visiting research ships, tie up when they're in port. For liability reasons, we need to keep it off limits to the public, except for special events such as public vessel tours. You can find many public docks in Newport where crabbing is permitted, though - try the South Beach marina area. Don't forget: In Oregon, you now need a license to catch crab, clams and other shellfish. Licenses are available whereever fishing licenses are sold, or can be purchased online from the Oregon Department of Fish and Wildlife.
