King Tides on the West Coast

Most people these days know about the effects of climate change. Every day the news reports about the change in weather patterns, the increase of extreme events, changes in snowpack, the retreat of glaciers. The list goes on and on. For the half of the US population that lives on the coast, we hear about sea level rise and coastal inundation and what we might expect for the future.

Still, does the average coastal resident really understand how rising sea levels and coastal inundation will impact them?

Washington, Oregon, and California are taking proactive steps to make sure that coastal residents, planners, and decision makers alike have the chance to see what sea level rise might look like in their own backyards. It’s called the King Tides Initiative, and every winter brings the opportunity to visualize what a rise in sea level might mean for communities and infrastructure along the West Coast.

the New South Wales’ Environment Department. They used the term “king tide” to define the high tides that occur when the gravitational pull of the sun and the moon is in alignment. Green Cross Australia continues this initiative, and recently launched a disaster resilience portal Queensland that connects climate awareness with disaster preparedness, working with the research community and advanced Facebook apps to empower people to take tailored steps to address hazard exposure.

These king tides, which take place during the winter along the West Coast, create higher than usual high tides that inundate roads, wetlands, water systems, and more. It’s a stunning preview of what we might experience regularly in the future as a result of rising sea levels.

West Coast states created their own King Tides Initiatives, with regional and local public outreach and education campaigns that ask coastal residents and visitors to photograph high tide events and share them on the photo sharing site Flickr®. By documenting and sharing photos, participants are helping create a living record of vulnerable areas of the coast. Because most photos are licensed under creative commons, they can be accessed and used by anyone. This makes king tide photos a resource for anyone, from teachers to planners to scientists, to communicate the impacts of climate change in a tangible way.

To learn more about the King Tides Initiative in California, I spoke with Marina Psaros, the Coastal Training Program Coordinator for the San Francisco Bay National Estuary Research Reserve.

What has been the biggest impact you’ve seen from the California King Tides campaign?

The king tides initiative is such a simple, powerful way to start a conversation about coastal hazards.  We’ve been able to reach a lot of people who don’t know much about coastal flooding and potential climate change impacts.  We recently held an exhibition of some of the photos at the California Academy of Sciences, and it was amazing to see

people’s immediate, visceral reactions to the images.  Concepts like “tidal inundation” and “sea level rise” are really abstract for most people, but a picture of water slamming up against a well-known landmark is immediately clear.

How can these pictures help us prepare for the future?

These images help engage people on the coast in a conversation about climate change and sea level rise. By participating in king tide events, coastal residents are helping to create a living record of areas that are vulnerable to flooding, and an online resource that can be used by anyone to communicate about coastal hazards. Creating new awareness through social media and other outreach, like the California Academy of Sciences photo exhibition, encourages people to think more proactively about the future of their communities. It also helps decision-makers visualize the impacts sea level rise could have on places where we live, work, and play. 

Can anyone get involved with King Tides?

 If you have a camera and can get to the coast, yes! Just check your state’s website for king tide events in your area, head out to the coast to take pictures of the king tides, and upload your images to Flickr®. While you’re on the Flickr® site, be sure to check out the rest of the photo pool.  We also encourage people to use these amazing pictures for their own communications – the images are available under a creative commons license. You can also get more information on the initiative through this recent Thank you Ocean podcast: http://www.thankyouocean.org/tag/king-tides/.

NOAA tides gauges and NASA satellites have been recording a global rise in sea level for 150 years.  This rise is linked to a number of atmospheric and oceanic processes; including changes in global temperatures, hydrologic cycles, coverage of glaciers and ice sheets, and storm frequency and intensity. Although high tides are a naturally occurring event, it’s a preview of water levels that climate models show might be a new “normal” in 100 years.

The motivation to start talking about hazard mitigation and adaptation is king tide photos of washed out roads, flooded homes, and shrinking beaches. We’ve got a lot to prepare for. Perhaps king tides are nature’s way of giving us a head start.

Measuring the Pulse of Puget Sound

Scientists at NOAA’s Northwest Fisheries Science Center in Seattle, WA are studying the life in Puget Sound’s surface waters—from microbes to fish and jellyfish— to understand this complex living system and shed light on how human activity affects its health . By understanding what groups of species live where and when and why, we can select measurable characteristics that tell us how the whole ecosystem is doing . This information can then be used by managers to protect and recover the life of Puget Sound. From Spring to Fall 2011, principle investigators Correigh Greene, Casey Rice, Linda Rhodes, and Kurt Fresh, and over 20 other scientists, technicians, and volunteers surveyed more than 80 sites from Commencement Bay in the south to Bellingham Bay in the north and Hood Canal in the west, representing of a range of natural conditions and human influence.

The Real Cost of Aquatic Invaders

I was interested to read recently that ballast water standards adopted by New York to prevent the spread of invasive species have prompted concern among several Great Lakes Governors, who say that the regulations will halt shipping in the St. Lawrence Seaway and jeopardize thousands of jobs. The new standards, which are more stringent than the Phase One standards proposed by the United States Coast Guard, require vessels transiting through New York waters to install ballast water treatment systems in order to protect the fragile ecosystems in New York and in the Great Lakes.  In 2009, the right of NY to establish standards via the Clean Water Act process was upheld in a New York Court of Appeals suite brought forth by the shipping industry.

The new standards have far reaching effects as all ships entering the Great Lakes need to pass through NY waters and must therefore install the new treatment technologies to “inactivate” biological organisms and pathogens. Systems inactivate organisms using a variety of methods including filtration, UV irradiation, deoxygenation, electrolysis, ultrasound, and something ominously called chemical biocide. Unfortunately, due to a relatively small number of “real world” tests of system performance in a variety of environmental and vessel conditions, there remains a high level of uncertainty with regard to treatment effectiveness.

Examples of aquatic invasive species presently found on the West Coast include the European green crab (Carcinus maenas), Chinese mitten crab (Eriocheir sinensis), zebra mussels (genus  Dreissena), cordgrasses (genus Spartina), and  Undaria pinnatifida. West Coast states have undertaken multimillion dollar projects to control or eradicate these aquatic invasive species.It is widely recognized that aquatic invasive species wreak havoc on our natural systems and infrastructure. By out competing native plants and animals, modifying habitat, and disrupting food webs, their effects can be seen in coastal ecosystems worldwide. What is also known is that invasive species cost the US billions of dollars annually in damage to coastal infrastructure, eradication and control efforts, and disruption to ecosystem services.

The West Coast Governors Alliance on Ocean Health (WCGA) recognized the threat of invasive species to the ecological, social, public health, and economic integrity of the region’s marine resources. The WCGA action plan acknowledged the great work already underway in the region on ballast water through the Pacific Ballast Water Group which acts as a forum for states to coordinate their ballast water policies. On the West Coast, California has had an effective ballast water management program in place since 2000 which has focused on performance standards as well as ballast water exchange. It has served as a model for the West Coast and, unlike the fears raised by the Great Lakes, has not resulted in decreased port activity.

In addition, the WCGA formed the Spartina Eradication Action Coordination Team focused on eradicating and preventing the spread of this invasive cordgrass. While not typically spread through ballast water, non-native Spartina dominates newly restored tidal marshes, changes the hydrology of estuaries by modification of tidal creeks and navigational channels, displaces thousands of acres of shorebird habitat, drastically reduces biodiversity, and decreases available intertidal habitat for commercial shellfish production.

I wanted to talk to someone who knows whether ballast water treatment standards will be effective on the West Coast to preventing the spread of invasive species. Mark Sytsma, the Director of the Center for Lakes and Reservoirs at Portland State University and former co-chair of the Spartina Eradication Action Coordination Team, was gracious enough to answer some of my questions.

Do you think the NY ballast water standards are the answer to preventing the spread and introduction of invasive species in NY and on the Great Lakes?

Mark: Standards are not the only answer to preventing new introductions, [ballast water] treatment is. Standards are [only] a way to direct and evaluate the treatment effectiveness. Unfortunately, no one knows what discharge standards are protective for our water resources. How many new introductions are acceptable? At this point, we don’t know the answer to that.

Are many of the invasive species on the West Coast introduced through ballast water?

Mark: Yes. Look at the 2004 Lower Columbia River Aquatic Non-indigenous Species report on our website about introductions to the Columbia. There is similar literature on SF Bay. It’s hard to imagine how some species could have gotten to the West Coast from Asia, except by hitchhiking in a ballast water tank.

Would ballast water treatment work on the West Coast?

Mark: I think everyone thinks that treatment is the answer. The question is how to treat [ballast water] quickly and effectively. There are a number of systems available and the California State Lands Commission has a report that describes the effectiveness and status of [treatment] systems.

What efforts has the Spartina ACT done to prevent the re-introduction of Spartina?

Mark: The funding that the WCGA provided for the Spartina action plan last year was used to develop environmental documents for Spartina treatment in Humboldt Bay and to do control of S. patens in Siuslaw estuary in Oregon. Both of these could be considered prevention, because infestations from these two sites threatens to spread to other areas on the West Coast. Certainly, those of us in Oregon see the Humboldt work as critical to preventing spread of Spartina to Oregon.

Thanks to Mark I was able to gain some insight from one of the experts on the West Coast. For me the questions raised by the Great Lakes Governors highlight the perceived tension between economic growth and ecological preservation. However, as we have seen in examples from the West Coast and around the world, failing to prevent and/or control aquatic invasive species is costly to infrastructure, jobs, and the environment. It is an investment in the future health of our economy and oceans that I think is worth making.

Guest Blog: Connecting Ecosystem-Based Projects Along the West Coast

The West Coast Ecosystem-Based Management Network (Network) recently held its 2011 Annual Meeting in Eureka, California.  The meeting brought together local project staff from 10 West Coast communities, representatives from ocean and coastal nongovernmental organizations (NGO)s, Washington, Oregon, Southern and Central California, and California Sea Grant, the National Oceanic and Atmospheric Administration (NOAA), and the West Coast Governors’ Agreement on Ocean Health (WCGA), along with a number of local, state and federal staff from the Humboldt Bay area. The meeting took place over two days and included over 60 attendees.

Early portions of the meeting highlighted the latest efforts taking place in coastal communities along the West Coast, including 10 sites ranging from San Diego to the outer coast of Washington State.  Project staff presented successful ecosystem-based management approaches driven by strong engagement with local stakeholders, including climate change planning, habitat restoration, and supporting local fisheries and working waterfronts, among other topics.  Discussion focused on exchanging local lessons and addressing common challenges, while revealing management experiences for the entire West Coast region.

Following the spotlight on local efforts, presentations were then given by representatives from NOAA and WCGA to provide updates on regional and national-level activities.  NOAA staff summarized the latest activities of the National Ocean Council and the preparation for new regional coastal and marine spatial planning frameworks.  The WCGA Executive Committee updated the group on the latest regional issues along the West Coast, and efforts of WCGA related to broader national-level planning and CMSP.  Finally, the four WCGA Fellows provided a briefing on their respective work plans and ongoing activities related to integrated ecosystem assessments (IEAs), climate change and sustainable communities, regional research planning, and a West Coast regional data sharing framework.

Throughout the meeting, the overlaps between the activities of the West Coast EBM Network and WCGA’s priorities were clearly apparent.  Many local communities throughout the West Coast are directly addressing pressing issues facing their local ecosystems and stakeholders, including preparing for climate change and supporting working waterfronts and local fishing fleets.  These align with the broader goals of WCGA Action Plan and the efforts of the WCGA Action Coordination Teams (ACTs) throughout the three West Coast states.  The activities and expertise housed in the WCGA ACTs were of great interest to the community-level projects at the meeting, and discussions centered on how a stronger connection could be made between the regional ACTs and staff supporting local-level efforts along the coast.

On a broader level, the other key lesson taken away from the meeting was the valuable opportunity to grow a mutually beneficial relationship between regional efforts like WCGA and coastal communities.  The WCGA is working towards successful regional approaches throughout the coast, and linking members of their ACTs, on topics that align well with EBM approaches at the local level.  Concurrently, the West Coast EBM Network is working to link coastal communities and successful on-the-ground outcomes, all of which could greatly benefit from a stronger relationship with the WCGA.  Further, local projects may serve as the ideal foundation for regional WCGA efforts, and illustrate the value of enhanced collaboration and planning along the coast through tangible benefits to local stakeholders and communities.

The West Coast EBM Network looks forward to continued collaboration with WCGA, including its Executive Committee, ACTs, and Sea Grant Fellows, to highlight the value of this innovative partnership and leverage the benefits to active coastal communities throughout the region.
