Walruses on a barrier island

OCEAN: RESEARCH ARTICLE

In September of 2013 the National Oceanic and Atmospheric Administration observed thousands of walruses hauling out on a barrier island off of Alaska.  On September 12th an estimated 1,500 to 4,000 individuals present and by September 27th there were approximately 10,000.  While similar events have been reported, scientists say it is a recent phenomenon. Walruses generally use floating ice in the Chukchi Sea to rest while feeding at sea but due to recent climate change and melting sea ice, it is more difficult for them—and other species, such as polar bears—to find resting areas.

According to Physics Today sea ice has reached its lowest area measurements since it began being measured in 1979-with a 55% decrease (7.5 million square kilometers to 3.4 million square kilometers). While sea ice has previously been very thick, containing multiple years of accumulation, the current sea ice is much thinner, containing just ice from one season.  The more transparent ice is much quicker to melt (Martin).

The effects on the individual walruses is varied and widespread.  They will be exposed to more stress, depleted food levels, more energy will need to be expended to find prey, trampling caused by stampedes of spooked walruses and increased predation (Knowles).  Disease also spreads much faster in populations that are overcrowded. There is evidence that certain mollusks, crabs and fish are moving northward and the shift in the food base is of a negative consequence for bottom feeders such as walrus and seal that prey on these species (Martin).  The walrus is currently listed as a “Threatened” species and the increase of stressors they face may push it over the edge to “Endangered.”

Unusual Mortality Event: California Sea Lions  

OCEAN: RESEARCH ARTICLE             

This 2013 Pacific sea lion pupping season has been a dramatic one. Rehabilitation centers have been inundated with over a thousand emaciated and dehydrated pups since the beginning of 2013, making it a record year for rescuers. NOAA has declared this an Unusual Mortality Event (UME) and this is the 6th overall UME for California Sea Lions.  According to NOAA, The Working Group on Marine Mammal UMEs lists 7 criteria to qualify something as a UME and an event has to meet one or more of these criteria to qualify as unusual:

  1. Marked increase in the magnitude or change in the nature of morbidity, mortality or strandings when compared to prior records.
  2. A temporal change in morbidity, mortality or strandings is occurring.
  3. A special change in morbidity, mortality or strandings is occurring.
  4. The species, age or sex composition of the affected animals is different than that of animals usually affected.
  5. Affected animals exhibit similar or unusual pathologic findings, behavior patterns, clinical signs, or general physical condition (e.g., blubber thickness).
  6. Potentially significant morbidity, mortality or stranding is observed in species, stocks or populations that are particularly vulnerable (e.g., listed as depleted, threatened or endangered or declining). For example, stranding of three or four right whales may be cause for great concern whereas stranding of a similar number of fin whales may not.
  7. Morbidity is observed concurrent with or as part of an unexplained continual decline of a marine mammal population, stock, or species.

This event most closely matches with item 1. above, however it likely qualifies under other criteria as well.

While the cause is currently undetermined, there are a few theories as to what is causing this mortality. The most publicized hypothesis is that due to less prey availability for these pinnipeds that the mothers are travelling further and for longer in search of food, making pups more likely to wander in search of their own sustenance. This is not only alarming for the health of the sea lion population but for the fisheries as well. Where did these fish go? What happened to cause such a drastic drop in population size? Answers to these questions are currently being sought out by the National Oceanic and Atmospheric Administration (NOAA) and the National Marine Fisheries Service (NMFS), and two other organizations have already gained preliminary results to the driving force behind this mystery.

Researchers from Australian Antarctic Division and Woods Hole Oceanographic Institute (WHOI) provide some insight to this conundrum whilst studying climate change in Antarctica. With global temperatures rising, there have been substantial changes to phytoplankton abundance, which is an integral source of food to fish and krill. They suggest that the trophic level have been and will be affected soonest, causing a chain reaction up the food chain from microorganisms to large cetaceans. This would be in agreement with what is being witnessed in California with less fish present for the sea lion population.

Green Roofs

Green Roofs may have been in use for thousands of years in Scandanavian countries. Birch bark waterproofing was used over a wooden roof and sod was placed on top of it to hold the birch bark in place. The natural oils in the bark maintained the water proofing.

Today's Green roofs used existing models as an end goal but needed to incorporate more flexible technology to accommodate changing architecture and materials.

Outer Cape Water Quality Initiative: How do grass and natural lawns affect water quality?

Pesticides seem an easy target, but they really direct us to a much larger picture.

Grass lawns don't need to be stigmatized as wrong or bad but perhaps a new balance can be considered between grass lawns and natural (indigenous vegetation) lawns. The Outer Cape's thin soil conditions are brutal, acid and nutrient poor. The natural indigenous vegetation, like the residents, seem to thrive on the weather abuse.

Grass lawns are usually seeded on top of six to eight inches of loam or topsoil. Fertilizers are added to stimulate growth and all sorts of seeds will be successful there. The leaves will be enriched, sending out chemical calling cards to insects. To reduce unwanted "weeds" herbicides may be used. To discourage insects, pesticides may be used. Frequent watering, additional fertilizers and continued use of pesticides and weed killer may be needed. Indigenous animals will find no familiar food or habitat there.

Natural (Indigenous) lawns can be seeded with conservation mix over an inch or two of indigenous compost (obtained free from local transfer stations). We usually rake the compost in a little, seed and then add a once inch layer of mulch (also free from transfer stations) to mimic natural soil profiles.

When transfer stations chip brush, branches and leaves, bacteria and microorganisms begin the decomposition process. The new material can be used as mulch and the dark final product can be used as compost. The benefit of using natural decomposition products is that they already have indigenous pH and nutrient content and host a full range of decomposers that keep on working. Keep the small chips and roots in the natural mix to protect natural diversity in the insect/decomposer community. This mix also welcomes indigenous volunteer seeds and will evolve naturally.

The benefits of natural systems include: creation of habitat for indigenous animals; natural erosion control (all grass creates runoff); naturally filters out sediment and excess nutrients with root/leaf stem systems; never needs mowing; never needs watering (except for the first growing season; never needs fertilizer; never needs pesticides; never needs herbicides. The benefits of natural lawn systems for our drinking water quality include: water conservation; pesticide free, herbicide free and fertilizer free. 

A BETTER BALANCE BETWEEN NATURAL AND GRASS LAWN SYSTEMS WOULD ENHANCE CONNECTED HABITAT AND REDUCE CHEMICAL INFILTRATION INTO OUR DRINKING WATER.

Safe Harbor Environmental Advocacy Initiative

This water quality initiative advocates the protection of drinking water resources on the Outer Cape. We support educational programs that develop awareness of our aquifer, which is recharged through ground water infiltration. We also encourage collaborative local partnerships, between town boards and stakeholder groups and between Outer Cape communities, to investigate the social changes needed to reduce chemical infiltration and improve our ground water recharge systems. The following discussion points outline the basic goals of the initiative. 1. Drinking water sourced from areas where household waste is infiltrated should be identified as an areas for improvement, through education. 2. Drinking water sourced from areas where lawn and garden chemicals are infiltrated should be identified as areas for improvement, through education. 3. Reducing infiltration of known carcinogens. 4. Reducing infiltration of non-degradable pesticides. 5. Reducing infiltration of biocide cleaners. 6. Reducing infiltration of growth hormones. 7. Reducing infiltration of antibiotics. 8. Reducing infiltration of petrochemicals. 9. Reducing infiltration of nitrogen and phosphorus. 10. Developing reliable, full spectrum monitoring programs. 11. Developing alternative choices for household chemical products. 12. Developing retailer support for chemical product alternatives. 13. Reducing storm water runoff with effective ground water infiltration systems.

We encourage leaders in Outer Cape Towns to discuss and support these basic goals. Discussions should include concerned residents and the capable contributors found on Planning Boards, Boards of Health and Conservation Commissions. Protecting our drinking water resources from chemical infiltration is a common goal that can unite local groups and create regional partnerships.

We support regional environmental initiatives. These initiatives work to conserve financial resources as well as natural resources. Local and regional partnerships contribute to successful initiatives by more effectively participating in stakeholder interaction and education.

Haiti Water Initiative

 OUR HAITI WATER PROJECT: EXCERPTS FROM OUR PAST EFFORTS Why spend money shipping water to Haiti when we could be sending water filters so they could have their own clean water? Think sustainability...

We had several good reasons for sending water filters to Haiti: Cholera is spread through contaminated water; bottled water is heavy and very expensive to ship and the empty bottles are creating plastic mountains. People should not be compelled to beg for life giving resources. Will a $20.00 water filter change the World? probably not by itself but if we send enough filters to change a family, school, a church or a village into a more sustainable, safer place to drink water, we may begin attracting attention to a new strategy and changing one small corner of the World.

The filter our we researched and selected is affordable ($20) can provide over 40 gallons per day of drinkable water from puddles...for a year. With Haiti's shipping infrastructure in ruins, we had to create opportunities for church groups and relief workers to deliver the filters for us, directly to those in need.

Dispatch From Iceland

 By Tessera Knowles-Thompson

Editor’s note: When one of our Researchers mentioned she was spending the summer in Iceland, we thought it would be interesting to have a researcher in place at this important Climate Change location, to collect anecdotal information from local fishermen and farmers about changes they were experiencing. As a further challenge, we asked Tess to see if any of the anomalies might be linked.

Crouching on the shore of Iceland’s Vatnsnes peninsula, I pick up a volcanic rock from the black sand, examine the vesicular texture and try to imagine the rapid transformation from molten lava to solid, igneous rock. Several arctic terns fly above; one dives at my head -- I duck to avoid the warning signal and I’m startled out of my geological reverie back into the present. Across the inlet, the corporeal mountain range -- absent arboreal growth -- appears to wrinkle here and stretch there along the horizon. In this moment, I am alone, I see no apparent signs of other human life, and I am filled with a sense of timelessness.[i]

 

ICELANDIC SURFACE CURRENTS

For the past couple months, I have been researching the impact of climate change in northern Iceland. More specifically, I have investigated the complex interplay between the atmosphere and ocean currents, and the possible effects of changing water temperature and salinity on Iceland’s ecosystems. Many changes are occurring, that is clear, but are they anomalies, or do they signal long-term trends?

The geographic location of Iceland makes it a particularly compelling case study. The Gulf Stream and Atlantic Drift Currents deliver warm surface waters to the region. As these waters are exposed to Arctic winds, they lose heat to the atmosphere and cool, becoming more dense and sinking. More warm surface water is drawn north as the denser water sinks. This process creates deep-water currents, which reappear in Tropical Oceans. This convective process is called the Thermohaline Circulation (THC). This heat exchange contributes to warmer climates in England and Western Europe, at latitudes similar to Siberia.

In recent years, influx of Greenland glacial melt water has raised concerns that lighter density fresh water blanketing denser, salt water, may alter ocean-atmosphere thermal exchange.  This could prevent transition to the density required to sink into the deep currents.[ii] In Iceland’s Sixth National Communication and First Biennial Report under the UN Framework Convention on Climate Change it is noted that: “deep water will be reduced when more fresh water is introduced to the Nordic seas because of melting of glaciers, thawing of permafrost and increased precipitation. With the time series available now it is, however, not possible to conclude that the flow of deep water is decreasing.”

Researchers in Iceland are particularly concerned with hydrographic variability, or the change in water temperature and salinity over a certain period of time, in the three main bodies of water surrounding the island – Atlantic water from the south, Polar and Arctic water from the Arctic Ocean and water from the Nordic Sea. Periods of increased/decreased temperature and salinity are associated with larger scale climatic variations, but since the mid-1990s, the continuous warm period has shown no signs of stopping. In the past 15 years, the waters in the south and west of Iceland have increased by 1–2°C. [iii]  Because of this, certain trophic (feeding) interactions have been affected. Examining how the smallest creatures are affected by changes in their ecosystem is an important tool in understanding how those further up the food chain will react.

The decreasing number of sand eels, for example, is impacting populations of creatures further up the food chain, and because of this, fisherman, researchers and others who regularly pay attention to the presumably more valuable species, are taking note: “Increasing sea temperature and growing mackerel numbers around Iceland are having a direct impact on the collapse of sand eel populations upon which birds like Puffins and Arctic terns depend.”[iv]

Because fish contribute to a large portion of the economy in Iceland, it is not surprising that a vast majority of research is focused on the related ecosystems. With a 758,000-km2 exclusive economic zone, Iceland is the 19th largest fishing nation in the world.[v]

While working on a hostel on a farm, named Ósar for the inlets it overlooks, on a still day, I can see patches of dark water, which I’m told are large schools of mackerel. Knútur, the owner of Ósar, has called this land home since birth—as did the families of his father and his grandfather. He can trace his paternal lineage back to the first Norse settlers to arrive in Iceland thirty-two generations ago, between the years 874 and 930. As he says, things have changed in recent years. The most notable are those that have impacted the local economy. Mackerel, for instance, have gotten considerable attention recently because they were only spotted occasionally in Icelandic waters until the mid 1990s when the period of warming began. In 2007, mackerel was declared a regulated fishery in Iceland’s EEZ.[vi] Today, as noted above, they are now regularly found in large schools in the bay.[vii] The Icelandic fishing fleet uses about 200,000 tons of oil per year, and the diesel engines used by most boats release black carbon, which settles on the Arctic sea-ice. When this dark soot collects on these generally white surfaces, more heat is absorbed, leading to increased melt.

Paradoxically, the warming climate has extended the growing season in Iceland, making it possible for farmers to experiment with new crops—at least one of which could be converted into a viable alternative to diesel fuel. In 2008, the Icelandic Maritime Administration and the Agriculture University of Iceland began a project in cooperation with a handful of pioneering farmers to experiment with the cultivation of rapeseed. The oil extracted from Rapeseed (a variation of which is Canadian oil, better known as canola oil) can be converted into biodiesel, which “would mitigate the total emission of carbon dioxide from the Icelandic fishing fleet.”[viii]  Knútur was one of the first to join the project, and successfully yielded 4.1 tons of 93 – 95% dry seed per hectare (~10 acres) at each harvest between 2008 and 2011.[ix]

Because fish contribute to a large portion of the economy in Iceland, it is not surprising that a vast majority of research is focused on the related ecosystems. With a 758,000-km2 exclusive economic zone, Iceland is the 19th largest fishing nation in the world.[xi]

“The Arctic has experienced substantial and rapid changes in recent years [...]” the EU Arctic Organization ACCESS states, “These changes are most likely caused by a combination of natural variability of the high-latitude climate system, anthropogenic changes in the radiation balance and subsequently in atmospheric and oceanic heat transports, and feedbacks in the air/sea-ice/ocean coupled system.”[xii]

The climate system is incredibly complex, and so it is important to keep in mind the multitude of layers that exist. The model below serves as a reminder that nothing exists in a vacuum – everything, both anomalies and trends, are associated with these large-scale systems.

https://www2.ucar.edu/climate/faq/aren-t-computer-models-used-predict-climate-really-simplistic

***

Lichens and moss both grow in abundance in Iceland. Lichens are “extremely versatile and often thrive in places where other vegetation has difficulty surviving”. Thus, lichens “account for an ever-greater share of mountain flora with increasing altitude, and lichens are often the first plants to colonise a freshly hardened lava field”. Some moss, I’m told, once trampled on, can take up to 100 years to grow back. [xxii]

Geological history proves that climate variations are natural, but with the unprecedented human activity of the post-Industrial Age, even the subtlest changes could signal a lasting trend. Therefore, the creatures (such as the sand eel) and plants (such as moss and lichen) most often overlooked deserve further investigation.

Without an immediate impact on our lives, or the lives of those directly connected to our web of compassion, this information remains just that: information to be filed away until another report makes headlines. The shock of a natural disaster often wakes us up, and some of us recognize the trends of increased regularity and proportions, but generally it is localized. Moreover, affected peoples and their allies remain preoccupied with the aftereffects, the immediate ramifications—mourning the loss of loved ones, rebuilding infrastructure, scavenging for or delivering food and water to those in need. Naturally, very few people pause to contemplate causes and connections to climatic events in faraway places. How could something that occurred thousands of miles away from us have an impact our lives? Even if we understand ocean currents, it is still a challenge to comprehend, let alone care enough to reflect on the ambiguous causes of these incidents, large and small, that are, perhaps, connected.

There are still many unknowns, and with the information we currently have available to us, we can make correlations, but clear causations are not yet possible. The trends, however, are indications that something has gone awry in the North Atlantic. Just like the drift current itself, the changes taking place are slow and, therefore, not easy to detect. Climate change in the Arctic is apparent, but the “drivers, evolution and ultimate impacts” remain unclear. [xxiii]

The more information we uncover about the ocean currents, the more prepared we can be for the changes that are to come. Regardless of the causes of the fluctuations in ocean temperatures, we need to know how this will affect us in the future. This includes the ways in which we are indirectly affected, which can only be understood by studying the impact that the changing climate has on the smallest of plants and animal species, and by the chain reactions that occur, ultimately leading up to us, humans.

Rising pH Levels Linked to Increased Spat Mortality. Economic, Ecological and Social Impacts on West Coast Oyster Industry

Ocean acidification is a present and future threat to a variety of ecosystems and biological processes (detailed in the OCEAN 30 issue by Safe Harbor), and one of the more recent and publicized victims of global warming is the oyster industry of the United States’ West Coast.

The oceans act like carbon sinks, and anthropogenic fossil fuel emissions have caused seawater to be 30% more acidic than pre-industrial times on a logarithmic scale. The eastern Pacific of the United States is particularly vulnerable to this decrease in pH because it already experiences deep upwelling and therefore inherently encounters more extreme acidic conditions more often. The driving force for the oyster farm failures along this shoreline is the inability for young oysters (known as spat) to develop successfully. The oysters are most vulnerable when young and just forming their calcium carbonate shells. This failure to thrive is due to a combination of extra energy required to form a shell (due to lack of necessary ions in the water now bound by acidic molecules) and possibly even dissipation of the fragile shells themselves.

Seed production in the Pacific Northwest plummeted 80% between 2005- 2009, with majority of the larvae dying within merely 2 days. To put into perspective how problematic this is the shellfish industry in this region contribute more than $250 million dollars to the economy annually and provides jobs for over 3,000 individuals. Parallel studies have started on the East Coast comparing conditions and bracing for future ocean acidification catastrophes. New Bedford, Massachusetts, is a major American port with shellfishing making up over 70% of its productivity, so job losses and community demographics would irreparably change for the worse if it is subjected to the consequences of ocean acidification like the Northwest Pacific has.

There has been much active research studying the mechanisms of spat failures and possible ways to rectify this problem both short and long term.  One example is Bodega Bay Marine Lab of UC-Davis working with Hog Island Oyster Company based in Tomales Bay, California. Hog Island raises their oyster spat in different water conditions in order to see the effects of various water quality scenarios, including excessive rain, water run-off, on the seed. The seawater of these tanks can be modified in real time if shell degradation is observed and documented for future hatcheries. Bodega Bay Marine Lab in turn records these fine scale aquatic changes in real time. It models how projected increased acidity will affect oysters and other shellfish in 10, 50 and 100 years in the future, and also how possible adaptations to counteract these caustic circumstances could help or hurt the oyster harvests.

Many of these susceptible oyster farms in the Pacific Northwest are multi-generational, family run companies who have to quickly troubleshoot this regional (and imminently global) disaster by changing techniques, importing spat, and monitoring water chemistry in order to adapt. One family, the Taylors of Shelton, Washington, have a separate oyster hatchery prior to planting in the Puget Sound. Hatcheries have been forced to incessantly monitor the incoming seawater acidity and either shut down flow is the water is too corrosive or add seagrass or sodium carbonate to help neutralize it more. This is a drastic change of how these companies have done things historically, but these alterations are a necessity in order to adapt to the changing seawater.

This, however, is just a stop gap. Models predict that corrosive water will be more prevalent at the sea surface and ubiquitous, up to 150% more, by the end of the century. The oyster harvest in the Northwest Pacific could increase by 25% over the next 50 years. This area is the canary in the coal mine- it is the first to show effects of increased acidification and gives insight on the dynamics of how these sensitive ecosystems will react. There are many short and long term strategies being constructed in attempts to rectify the situation, especially because of potential devastating consequences rippling up the entire food web. This research alone, costs from tens to hundreds of million dollars to complete. It is not cheap researching this evolving problem due to fossil fuel emissions; however, losing any of these shellfishing stocks would be detrimental on a much larger scale and immeasurable effects to local economies.

Recycling Resources

Safe Harbor is a multidisciplinary environmental consulting group specializing in environmental risk assessment, coastal erosion response, conflict resolution and education. The Reallocation of Resources Initiative (RRI) was created as a pilot project in response to our organizations involvement in local building and understanding of the complexities surrounding natural and manmade resource recycling. RRI’s main goal is to decrease the amount of resources diverted to landfills by connecting local communities and green builders with reclaimed resources for Reuse with future construction and energy generation.

Lighthouse Vision Retreat

Screen Shot 2017-02-08 at 1.46.33 PM.png

Race Point Lighthouse, Provincetown Massachusetts  On October 24th through 25th, our team stayed on the edge of the Earth at Race Point lighthouse for a vision retreat.  I asked everyone to bring with them a vision of how they want to feel about working with Safe Harbor. I wanted us to share a vision of what Safe Harbor could be and develop some reachable goals together for the coming year.

I offered a field trip through the linked habitats of salt marsh, dunes, upper and lower beach and intertidal zone. We compared diversity with the degree of stress in each habitat. I had been involved in planning the restoration of this marsh.

We shared bedrooms in the restored Keeper's Quarters. The lighthouse has electricity, and amenities.  I asked our new Intern Zoe, to act as Retreat Coordinator.  Zoe coordinated arrangements and transportation with the Lighthouse Foundation and created menu choices for lunch, dinner and breakfast. After dinner we made time to share our thoughts together.

Funding for this retreat comes from an Environmental Vision Grant through Safe Harbor’s environmental education fund.

The Retreat:

Our Vision Retreat Handbook includes site specific information on marsh restoration, currents, erosion and deposition, as well as some commonly found plants and animals we are likely to encounter.

Wind Energy

A WIDE VARIETY OF INNOVATIVE VAT SYSTEMS ARE EMERGING.

THE SLIDE SHOW PRESENTS A FEW ALTERNATIVE WIND SYSTEMS THAT WE BELIEVE ARE WORTH CONSIDERING. THE ACCOMPANYING BOOKLET PROVIDES SOURCES. VAT NAYSAYERS POINT OUT THAT THESE SYSTEMS HAVEN'T BEEN ABLE TO PRODUCE PROMISED RESULTS AND SHOULD BE DISCARDED. IN RESPONSE TO THAT, SAFE HARBOR BELIEVES THAT SUSTAINABLE ENERGY SYSTEMS SHOULD BE AFFORDED THE SAME BIRTHING PERIOD AFFORDED TO CARBON. REMEMBER THE THREE REASONS WHY AUTOMIBLES WOULD NEVER BE SUCCESSFUL? "THEY ARE UGLY, THEY BREAK DOWN AND THEY SCARE THE HORSES.".

FUTURE ZONING ON THE OUTER CAPE MAY CONSIDER WIND SHED VALUES AS A PROTECTED NATURAL RESOURCE. THIS WOULD PROTECT NEIGHBORHOOD ACCESS TO WIND AS AN ENERGY RESOURCE. FORWARD LOOKING COMMUNITY PLANNING SHOULD CONSIDER ENERGY ACCESS ISSUES SUCH AS ONE NEIGHBOR'S TREES OR STRUCTURES BLOCKING WIND OR SOLAR ENERGY TO ANOTHER NEIGHBOR'S PROPERTY.
