Winter storms push debris ashore in Pacific Northwest

A series of winter storms hailing strong western and southern winds has pushed tsunami debris ashore in the Pacific Northwest.

The debris ranges from larger to small objects, and is mingled with other nearshore debris along Oregon and Washington's beaches.

One such item, a section of a Yamaha boat, is believed to be tsunami debris and was found by a local resident on a beach north of Yachats, Oregon. 


Like other tsunami debris, it was covered in a variety of invertebrate organisms. It included several individuals of Mytilus galloprovincialis, or Mediterranean mussels (despite its name, it can be found in Washington, the Puget Sound, and also in Japan and other areas in Asia), gooseneck barnacles, and sea anemones.

The section was approximately 13.5 by 21 inches and included a length of rope wrapped around a rail on the outer section.

There is no confirmation that this particular item is tsunami debris, however it is currently being evaluated.



The full section is shown here, measuring approximately 21" in length (Photo: John Chapman)

As winter storms continue into March, it is possible that more large pieces of debris could wash ashore during storms.  If you happen to find a piece of debris, please refer to my resources section for options to report the debris. Any live organisms should be reported to Hatfield Marine Science Center's Invasive Species Laboratory, via the reporting form.

First Japanese Boat of 2014 Washes Ashore

On January 15, 2014,  the first boat of Japanese origin was reported in Twin Harbors Beach State Park in Westport, Washington.  While the boat didn't make the evening news, it was quickly collected and examined by biologists of the Washington Department of Fisheries and Wildlife and Oregon State University.  Assuming that the boat was Japanese Tsunami Marine Debris (JTMD), this means the boat was in fact drifting at sea for nearly three years before finding its way on shore.  This would be a testament to the fact that there certainly is still tsunami debris drifting around the Pacific Ocean (likely within the gyre system), and will continue to make its way to shore in the following years.

The boat, which was 22 feet long and covered in gooseneck barnacles, the giant barnacle Megabalanus rosa, ten species of algae, and at least one species of oyster, did have Japanese writing on it, which informed investigators that the boat was called the 'Dai Jyu Hachi Ei-Fuku-Maru', or the "18th Prosperous Fortune". None of the organisms were alive.



The boat's inscription reads "18 栄福丸" [Photo: WDFW]

The boat is in the process of being cross-checked with the Japanese Consulate to determine whether the boat is in fact JTMD.  However, the organisms present have led biologists at Oregon State University to believe that the boat is tsunami debris.

Another boat?

Several months after the last vessel was reported as washing up on North American shores, a new boat has washed up on a Long Beach, BC beach.

Tofino is located on the mid-Southern coast of Vancouver Island. [Tofino-bc.com]

After a series of typhoon-related storms in the Pacific, a boat drifted ashore on Sunday, October 6 in Tofino.  The boat is approximately 20 feet long, and was covered in pelagic gooseneck barnacles- common occurrence on existing tsunami debris that has been floating in the ocean for a long period of time.

This happening is likely to be echoed in coming months, as winter storms pick up and wash heavier objects inshore in the Pacific Northwest.   Stay tuned!

One More Boat Washes Ashore in British Columbia

And, in a news story that was not very widely reported, around May 1 another Japanese vessel has washed ashore on Swindle Island, Queen Charlotte Sound of British Columbia.  The vessel, another small skiff, could still float, and had Japanese characters written on the bow.  More information as I can find it!

First Piece of Tsunami Debris Confirmed in California

Surprisingly, the first widely-reported piece of news in weeks is really not news at all.  However, I wanted to revisit the story here.

The boat that was washed away ashore in Crescent City, California on April 7th has now been officially categorized as the 27th piece of confirmed tsunami debris by the Japanese government and NOAA.  The boat was discovered with writing that linked it to Takata High School in the city of Rikuzentakata, Japan.  Upon its discovery, the school was called and and an instructor immediately recognized the vessel as belonging to his school, and that it was in fact washed away in the tsunami. 

It has taken several weeks for the boat to be officially confirmed as tsunami debris, through verification by NOAA, the school, and the Japanese Consulate.

OBC Exclusive: Boat found in Southern Oregon, Quickly Removed

Greetings, readers.  As you can tell, the amount of debris washing up in past weeks has been very low.  The last major piece of debris reported was the boat that washed up in Long Beach, Washington- complete with live fish.
However, earlier this week, a vessel that appeared to be an artifact of the 2011 tsunamis was found in Oregon by a fellow biologist and colleague, Jeremiah Psiropoulos. 

Jeremiah encountered the vessel while working in a particularly important wildlife area- a critical habitat area for western snowy plover.  Western snowy plover (Charadrius alexandrinus nivosus) are particularly cute little sea birds that have been listed as 'threatened' under the Endangered Species Act (ESA) since 1993.  Oregon's sandy shores and coastal dunes are essential nesting and breeding grounds for this bird.  In order to minimize impact of tourists, media, and other visitors in the area, the boat was immediately removed.

I interviewed Jeremiah about his find, which I will share with you below.  My questions are in italics, and Jeremiah's answers are in plain text.

------------------


Jeremiah,
Thanks for taking the time to let me interview you! My understanding is that on April 22nd, you found a vessel that appeared to be from the 2011 tsunamis on a beach in Oregon. 

 I would like to ask you a few questions about your recent find, how you responded, and your feelings regarding ethical responsibility or environmental stewardship when it comes to exciting beach finds like this one.

First, tell me a little about yourself.  What is your background and current occupation?
My name is Jeremiah Psiropoulos. I am a native Oregonian who grew up in the Umpqua valley. I have always been very fond of Oregon’s biodiversity and specifically its fish and wildlife. I have degrees from the University of Oregon in Environmental Studies and Oregon State University in Fisheries and Wildlife Sciences. I am currently working for the USDA APHIS (Animal and Plant Health Inspection Service -  http://www.aphis.usda.gov/) Wildlife Services as a wildlife specialist monitoring and controlling predators that depredate ESA-listed (Endangered Species Act) western snowy plovers (Charadrius alexandrinus nivosus) during the breeding and nesting season.

Learn more about Snowy Plover here: http://www.westernsnowyplover.org/

Please tell me a bit about when, where and how you found the boat.  How did you happen to be in that area?
I am responsible for monitoring two nesting areas that are used by the snowy plovers known as habitat restoration areas (HRA’s). Both are in the Coos Bay, OR area, the first being Coos Bay North Spit and the second is the Tenmile Creek. Around 10 am on April 22nd, I was traveling south along the beach near the jetty on the north spit and found a boat on the edge of the rack line on a receding high tide. The area where I found the boat was within the snowy plover closure area which limits traffic to foot and horse only on wet sand. Due to these restrictions it receives very little traffic and had yet to have any public pass by that morning.

Can you describe the boat in detail- any writing, size, condition of the boat, etc.
The boat was approximately 20 feet long with an open bow. It had gently sloping gunwales with a live well in the bow and an open area in the stern, presumably for a motor. It was blue color with a red keel that was only apparent after scraping gooseneck barnacles from the hull. I could not find any writing or other marking that indicated its origin. The boat was pretty battered and full of water. It appeared that there was at one time some sort of bimini top attached to the gunwales.

Did any thoughts immediately come to mind when you came up the vessel?
My first thought was that the boat didn’t look like the type of boats used in the area. I knew that debris from the tsunami disaster was washing up in the neighborhood and figured that it was likely of Asian origin.

What types of creatures or sea life were on the boat? How long do you think it had been there?
The hull of the boat was covered in pelagic gooseneck barnacles (Lepas anatifera) , there were also limpets and bivalves attached to the interior. At least one bivalve was later identified to be of non-native origin.

How did you respond- what agencies did you call, and what was the process of removing the vessel?  How long did it take?
My job requires me to work closely with many other state and federal agencies that have interests in and around the HRA’s I patrol. I first contacted the recreation tech with the BLM (Bureau of Land Management) whom I knew to be in the neighborhood. Her job is to ensure compliance of plover closures and other beach rules by recreationalists. Next I contacted the state parks patrol officer who patrols this beach. I knew that everything below the high tide line was the responsibility of state parks and they had a specific interest in possible tsunami debris.

Tell me a bit about why you chose to contact an agency rather than leave the vessel there, and why should others perhaps consider doing the same?
I did this for several reasons. One, I had been instructed when I came on the job who to contact in the case of different events/occurrences on the beach. Secondly, I have a responsibility to protect nesting snowy plovers and knowing that these types of events could attract crowds and media I knew I needed to act quickly to avoid such an event. Being a ground nesting bird, snowy plover nests are very vulnerable to disturbance. The areas where they lay eggs need to remain clear of people, cars, pets, ATV’s etc. People, even well-intentioned ones, have capability of easily trampling nests or stressing and flushing birds leaving the nests open to predation.  I also knew that the boat likely contained non-native species that could have deleterious effects on our ecosystem and needed to be removed before any organisms had the chance to get established. Lastly, debris from Japan is part of a disaster that caused death and destruction to many people. The artifacts that show up on our beaches need to be treated with respect for the victims of this disaster and lives affected by it.

What do you think are important considerations for people who might find debris- in terms of respect for former owners of the objects, or thoughts for wildlife species in the area?  When should one consider keeping an item versus reporting it?
If a member of the public finds an artifact that appears to be of Japanese origin and that may have value both commercially or culturally they should definitely contact the appropriate authority (State Parks in most cases). This should be done for several reasons. For example, if the object can be returned to the rightful owner than it needs to be. If the object is of cultural importance then it is proper to respect the culture and customs of the country of origin. I think it is important to remember that these artifacts aren’t trophies, but the product of a massive event that caused great human suffering and need to be treated as such.

What are your feelings on media involvement or actions that should be taken in circumstances such as this- is it best to get the object out as soon as possible, or is it better to bring social attention to the issue?




Although the public has the right to know what is happening on their public beaches, I believe it is really in the best interest of everyone involved to contact the proper authority so they can make an attempt to remove it as soon as possible. Some of these objects can pose a threat to public health or the environment and the proper authorities can quickly identify and start the process of mitigating any threats. Once the appropriate agency is involved then they can determine whether or not to contact the media based on the individual circumstances of the situation.

Do you have any parting thoughts?
I believe it is the job of the general public to inform themselves on the impact they may have when visiting our natural areas. Working with western snowy plovers I have become very familiar with the negative impacts carelessness can cause on vulnerable resources. It is your responsibility to know which areas are open to the public and which are prohibited, whether or not dogs or horses are allowed, and the negative impacts of negligence.

I would really like to thank Jeremiah for his time answering my questions, and for allowing me to share his story and photos on my blog!  I believe that his consideration for both cultural respect and biological diversity are something that all beachcombers should emulate when using the beach, or finding possible tsunami debris.  Please visit my Resources page to find out who to contact should you find debris.

To learn how you can volunteer your time to help the recovery of the western snowy plover, or to learn more about the plover, please visit http://www.westernsnowyplover.org/volunteering.html.

Lastly, if you have found debris and would like to share your story or photos with me, please email me at marinecowgirl@gmail.com.

Relics Wash Ashore as Bulk of Debris Approaches US West Coast

Another Sacred Object Washes Ashore in Oregon

After a 16-foot beam of a Japanese Shinto Shrine washed ashore in Oceanside in March, a very similar 14 foot object has now washed ashore in Florence.  The wooden beam or kasagi appears to be the top part of another Shinto shrine- of which Japan has approximately 80,000- represents a spiritual relic for the Japanese culture.  Even though not all Japanese citizens practice the Shinto religion, Shinto shrines are culturally unique structures that are found in many important natural areas across the country.

The kasagi beam washed ashore near the Siuslaw River this week. The Japanese Consular Office in Portland has been contacted, but the situation will likely be deferred to Jinja Honcho, the Japanese Association of Shinto Shrines.

Boat Covered in Barnacles Washes Ashore in Crescent City, CA

A 21-foot boat has washed ashore in Crescent City, California, making it one of the first larger objects to wash ashore south of Oregon.  The boat is covered in thousands of pelagic gooseneck barnacles (Lepas anatifera), a common oceanic colonizer, giving it a very odd appearance.

Once some of the barnacles were removed, the Japanese lettering for "Takada High School" was apparent- the high school was in Rikuzentakata City, which was heavily hit by the tsunami. The boat is currently being verified as tsunami debris, but it likely originated from the natural disaster. I will post more information as it is available.

NOAA Updates Marine Debris GNOME Graphic


Finally, NOAA has updated the GNOME tsanami debris model for the first time since early March.  As larger objects wash ashore on the west coast of North America, the projected critical mass of the debris moves towards US shores.  Click on the map for a larger version on NOAA's webpage.

Boat with Live Fish: Confirmed Tsunami Debris

This just in from the Washington State Marine Debris Task Force:

The boat that washed up with five live fish in it last week has officially been confirmed as tsunami debris.

The boat, named the Sai shou maru was indeed swept away by the March 11, 2011 tsunami.  The Japanese consulate has contacted the owner, who does not wish the boat returned.

The Sai shou maru is currently being cleaned up for display at the Columbia River Marine Museum in Astoria.  In addition to the five fish, there were 30 to 50 other species of marine organism attached the boat.

Another Ghost Washes Ashore

Another Ghost Boat
Long Beach, Washington seems to be especially good at accumulating tsunami debris these days (See my map of archived debris)

In the continuation of this, another ghost vessel has washed up on the Long Beach shoreline as of last week.  The 18-foot vessel is currently in the process of being confirmed as tsunami debris.  Upon clearance of mussels, algae, and barnacles on the bow, Japanese writing and an identification number that appears to read: IT3 - 43282 was legible.

More as it arrives.

Another Soccer Ball Found
The soccer ball that washed up almost a year ago in Middleton Beach, Alaska made countless headlines, as the writing on the ball traced it back to a victim of the 2011 tsunamis.  Now, another soccer ball has been found, along with other confirmed debris from the disaster during a venture by environmental activist project, the Ikkatsu Project.  The Ikkatsu Project has produced a film entitled  'Roadless Coast', which takes place on the 70+ mile roadless route in northern Washington. The film details the expedition of a team of kayakers which explore the Roadless Coast in search of debris from the tsunami.  Many items were found, including a soccer ball, float, bouys, lumber, children's potty seat, a washer and dryer, medicines, and various other objects.

Hitch-Hiking Fish: A Biological Rarity

For the first time, live vertebrates have been found to have made it all the way from Japan from the United States. When a blue fiberglass boat (one of many that have washed up) appeared on the shores of Long Beach, Washington, crews headed out to investigate biological risk and plan removal. But what they found surprised them. Hitching aboard the boat's hold were five live fish, native to Japan. The fish had apparently made their way into the boat, and floated across in the sea water within the
vessel.

The fish, Oplegnathus fasciatus- also known as striped beakfish, striped beakperch, barred knifejaw, or rock bream are native to Asian waters in Korea, Japan and China.  The fish probably entered the back compartment of the vessel where they were found, then became stuck as the boat drifted across the Pacific.

The sheer probability of this is slightly amazing- in order for this to happen, the fish must have first been trapped inside the vessel, and survive months of stressful through storms, temperature variations, and jostling.  Unlike intertidal invertebrates, which are used to a stressful and changing environment, fish are much more delicate and likely to die from stress or abrupt changes in water characteristics.  The reason for this is a temperature-sensitivity factor called 'Q10' or temperature coefficient.

Q10 is the rate at which your metabolic rate increases with an increase in ambient temperature.  More specifically, for every temperature increase of 10 degrees celcius, your metabolic rate is multiplied.  Fish have a notoriously low Q10, meaning that a slight change in water temperature can actually double their metabolic rate.  A Q10 of '2' means that for every 10 degrees celcius, an animal's metabolic reaction rates double. A Q10 of '3' means that it would triple, and so on.
Q_{10}=\left( \frac{R_2}{R_1} \right )^{10/(T_2-T_1) }
The equation for Q10, or the temperature coefficient.
Here, R = rate of biochemical (enzyme) reactions within the body, both original (R1) and with the new temperature (R2)
and T = body temperature (generally in Celcius), both original (T1) and in new temperature (T2).

Most animals fall within a Q10 range of 2 or 3.  Also, keep in mind that most critters (such as you and me) can use 'homeostasis' or maintaining a particular body temperature to prevent abrupt changes.  Enzymatic activity in animals (the chemical reactions that keep your body going day to day) is very sensitive to temperature, and therefore it is essential that we keep our body temperatures in a relatively stable range from which it rarely changes- say 98.6.  That is why a fever of 102 degrees might be so dangerous for us.  Each species has a slightly different 'peak' temperature where their bodies operate best at.  We can slightly increase or decrease our metabolic rate (exercising, or sitting on the couch), but to a very minor degree without serious consequences.

Q10 reaction rate chart.  Read more at: http://www.calpoly.edu/~bio/EPL/pdfs/SampleLectureBIO162.pdf


Fish have a wide range of Q10 values, but as a result of being poikilothermic (having changing body temperature) unlike mammals, they are much more sensitive to temperature changes.  Think of how sad your goldfish looks if you change his water and make it a little too cold, or a little too warm- his metabolic rate is going crazy.




It is a wonder that these guys survived their entire voyage.  Unfortunately, of the five fish, only one is still alive- the others dying in transport and removal (likely from heat and handling stress once the boat washed up), showing how delicate they really are.  If the lone survivor continues to thrive, it will be placed on display at the Long Beach Aquarium.  I'm rooting for him.


If you'd like to learn more about temperature regulation in animals, there is an excellent introductory lecture at: http://www.calpoly.edu/~bio/EPL/pdfs/SampleLectureBIO162.pdf. 
Enjoy!
