Whistler Water’s Glacial Appeal

Bottled water companies often use images of nature to entice consumers with the allure of pure, remote sources. Whistler Water, a Canadian bottled water company, boasts that its water comes from a glacier-fed aquifer at the base of the coastal mountain range in British Columbia. The company draws heavily on nature and mountain themes in its advertising and images. Its social media pages brim with photos of hikers atop snowy peaks, lush forests and bubbling streams. Like many companies, however, the environmental content and sustainability promoted by the company belies its plastic products and unsustainable wellspring.

Whistler Water has incorporated sustainability into their company by using 100 percent recyclable bottles and Forest Stewardship Council certified boxes, which indicates the boxes are sourced from responsibly managed forests. However, the company’s steps towards more sustainable resource use do not directly address climate change, which is taking its toll on Whistler Water’s vital resources. According to a study published in 2015, glaciers in Western Canada––including those of the coastal mountain range––are shrinking rapidly. The study projects glaciers in western Canada will lose 70 percent of their volume by the year 2100. Place Glacier, which feeds Whistler Water’s underground aquifer, is among those quickly decreasing in mass.  

GlacierHub caught up with Richard Wilk, professor emeritus in the Department of Anthropology at Indiana University, Bloomington. The branding of bottled water is an area of interest for Wilk, who has published the results of his research on the cultural influences on marketing of bottled water and consumer opposition of the product. He noted that bottled water companies use both nature and technology to provide a sense of cleanliness and safety. Whistler Water for example, uses nature and technology to promote the purity of their products– advertising ancient, untouched glaciers as well as BPA-free, recyclable bottles that make sure their water remains “exactly as nature intended.” Wilk said this was “a great example of how [companies] use nature as a form of authentication and then turn around and use technology as a form of authentication,” stating “nature undoes the danger of technology and technology undoes the danger of nature.”

The emphasis on both nature and technology provides a false sense of security to consumers who would be afraid to drink water directly from the source or even straight from the tap. Wilk explained distrust of public water can be traced as far back as mid-19th century London, to the discovery of cholera spreading via a public water pump. Modern issues such as the contamination of drinking water inFlint, Michigan have only fueled suspicion.

Plastic water bottles have come to dominate the beverage industry. In 2016, bottled water became the most consumed beverage in the US. The global bottled water industry is predicted to be worth $334 billion in 2023, which would be a 55 percent increase from the $185 billion it was worth in 2015. Despite the industry’s success, bottled water remains a controversial product. Wilk told GlacierHub that bottled water usually comes from a public source but is used for private profit, a process with which many take issue. Whistler Water is a prime example of using a public freshwater resource for private gain. As of 2014, British Columbia (where Whistler Water is produced) did not regulate groundwater use, nor did it charge companies for groundwater withdrawals.

Environmental concerns also plague the industry. Whistler Water has tried to create a natural, pure image for themselves, but plastic bottles depict one of waste. In an age where single-use plastics have become cultural ignominies, reusable water bottles have been promoted as a sustainable alternative. Wilk told GlacierHub, “water bottles can be status symbols because you have the money to buy the bottle and you’re conscious of environmental problems.” This month, Whistler Water posted an advertisement to their Instagram, Facebook and Twitter pages showing a woman refilling her reusable water bottle with a four-liter plastic jug of Whistler Water–the latter undercutting the sustainability that the former could support. While Whistler Water does use 100 percent recyclable bottles, Wilk says this is not a cure-all. His reasoning is that “we know most bottles are not recycled—to say this absolves [Whistler Water] of any responsibility is disingenuous.”

Whistler Water is not the first bottled water company to use glaciers as a marketing device. The water company Svalbardi sells 80 Euro bottles of polar iceberg water, which derive ultimately from glaciers in Greenland, and Alaska Glacier Products sells bottles of water sourced from Alaska’s Eklutna Glacier. As part of his research, Wilk invited 25 marketing professionals and professors to engage in an activity in which they proposed ways to market water. Among them was selling meltwater from named glaciers and jacking up the price as the glaciers shrunk. As controversial as this marketing technique might seem, companies, including Whistler Water, employ similar tactics. The company says its water comes from “ancient glaciers located high in the alpine peaks of the coastal mountain range just north of Whistler, British Columbia, Canada,” appealing to the consumer with its rare resources.

Glaciers provide drinking water to communities around the globe. But they continue to be threatened by environmental dangers. Waste products of human society, such as carbon dioxide, which warms the atmosphere, and plastic particles that have become ubiquitous are causing glaciers to shrink and have littered their surfaces with plastic. Some community-based organizations in mountain regions have sought to address plastic pollution, including Nepal, which has banned single-use plastics in the region around Mount Everest. As with addressing single-use plastics, combating the threats glaciers face from climate change will also require drastic policy and societal changes.

The Growth of Simple Plant Life in Extreme Conditions

From Polar Biology: “Aerial dispersal in the colonization of bare ground by lichens in the polar regions remains poorly understood. Potential colonists may arrive continually, although extreme abiotic conditions limit their viability. [The authors] investigated the vegetative dispersal of Antarctic macrolichens along a successional gradient (from 8.6–7.0 ka BP up to present) after glacial retreat on James Ross Island, in the Antarctic Peninsula region.“

Future Warming and Water Resource Availability in the Tibetan Plateau

From Earth Science Reviews: “Future climate warming is expected to have a significant effect on the operation of Earth and Ecological systems. A key concern in the future is water resource availability. In regions such as the Tibet Plateau (TP) lakes and glaciers appear to be highly sensitive to climate forcing and variations in the size and extent of these systems will have profound socio-economic and environmental consequences in South and Central Asia.”

What Does Glacial Retreat in Alaska Mean for the Salmon Population?

From BioScience: “Glaciers cover 10 percent of our planet’s land surface, but as our climate warms, many glaciers are shrinking. As glacial retreat proceeds northward along the Pacific coast of the continental United States, through Canada, to Alaska, it is creating new stream habitat for salmon that has not existed in millennia. When and how will this new stream rollout happen? Where will salmon be distributed in the future?”

Roundup: Harbor Seals, River Communities and Iceberg Melt

Glacial Habitats of Alaskan Harbor Seals

From Marine Mammal Science: “Harbor seals, Phoca vitulina, use diverse haul-out substrates including ice calved by tidewater glaciers. Numbers of seals at glacial and terrestrial haul-outs on the southeastern Kenai Peninsula, Alaska, were assessed using aerial, vessel, and video surveys. Mean annual abundance at glacial and terrestrial haul-outs differed temporally. From 2004 to 2011, numbers of seals counted during the molt increased 5.4%/yr at glacial haul-outs and 9%/yr at terrestrial haul-outs while numbers of pups increased 5.0%/yr at glacial sites and 1.5%/yr at terrestrial sites.”

River Invertebrate Biodiversity

From Nature Ecology & Evolution: “Global change threatens invertebrate biodiversity and its central role in numerous ecosystem functions and services. Functional trait analyses have been advocated to uncover global mechanisms behind biodiversity responses to environmental change, but the application of this approach for invertebrates is underdeveloped relative to other organism groups. From an evaluation of 363 records comprising >1.23 million invertebrates collected from rivers across nine biogeographic regions on three continents, consistent responses of community trait composition and diversity to replicated gradients of reduced glacier cover are demonstrated.”

Greenland’s Freshwater Budget

From Nature Geoscience: “Liquid freshwater fluxes from the Greenland ice sheet affect ocean water properties and circulation on local, regional and basin-wide scales, with associated biosphere effects. The exact impact, however, depends on the volume, timing, and location of freshwater releases, which are poorly known. In particular, the transformation of icebergs, which make up roughly 30–50% of the loss of the ice-sheet mass to liquid freshwater, is not well understood. Here we estimate the spatial and temporal distribution of the freshwater flux for the Helheim–Sermilik glacier–fjord system in southeast Greenland using an iceberg-melt model that resolves the subsurface iceberg melt. By estimating seasonal variations in all the freshwater sources, we confirm quantitatively that iceberg melt is the largest annual freshwater source in this system type.”

Supercool water found near glaciers

Temperatures in Spitbergen, Norway may be below freezing, but the water around the Glacier Front isn’t frozen, researchers Eugene Morozov from Shirshov Institute of Oceanology, Aleksey Marchenko from the University Center in Svalbard, and Yu. D. Fomin from Moscow Institute of Physics and Technology, found,

This process of supercooling, also known as undercooling, happens when the temperature of a liquid or a gas drops below its freezing point without it becoming a solid. Experiments on Youtube show people taking liquid water out of their freezers, and pouring it on white plate under normal temperature. As the water hits the plate, it instantaneously turns into ice.

There are two methods for making water supercool. The first method, like the one show in Youtube videos, can only be achieved when water is extremely pure. Impure water has ‘nucleation sites,’ where water molecules gather and gradually solidify during the freezing process. People can make supercool water with a simple refrigerator and a bottle of pure water.

The other method relates to salinity and water pressure. Supercool water can occur under conditions of heat removal, different rates of heat and salt diffusion and rapid pressure decrease, chemists Valeria Molinero and Emily Moore in University of Utah found after much experimentation in 2011.

With higher pressure, water will freeze at temperatures below 0 degree Celsius. In addition, higher salinity will also result in a lower freezing temperature. According to Figure 2, the freezing point will change depending on salinity and water pressure.

Previously, supercool water had only been created under laboratory conditions. However, the new findings from Eugene Morozov and his colleagues show that there is Glaciohydraulic supercooling water around the glacier that mixes and cools with high salinity and high pressure water.

The bottom of the glacier is approximately 15 m from the sea surface. The melt water (fresh water) flows from the glacier at a temperature of 0 C. After mixing with surrounding seawater with a temperature of – 1.8 C, melt water cools to temperatures lower than -1.8 C while ascending to the surface. As it surfaces, its temperature is close to the freezing point of seawater(-1.8 C). That temperature is lower than the freezing temperature of freshwater and its internal energy does not reach the equilibrium state required for freezing. This freshwater from glaciers cools to temperatures lower than freezing without becoming ice.

The finding in Spitbergen is supported by research from Dr. Igor Dmitrenko, who works for Leibniz Institute of Marine Sciences at University of Kiel. He found that supercool water also exists in polynas, an area of open water surrounded by sea ice. However, this condition cannot be observed all the time since it cannot exist for an extended period. Supercooling water will transfer to the other states of water in a short time. It could play a crucial role in sea ice formation, researchers say.

“While frazil ice [needle-shaped ice fragments in water] formation in the Arctic was carefully examined over the past several years for the St. Lawrence Island and the Storfjord polynyas […] the processes controlling the sea ice growth due to supercooled water and frazil ice formation over the Siberian Arctic shelf remain poorly understood, owing to the scarce instrumental records and extreme climatic conditions,” Dmitrenko wrote in his study.  “From these considerations, supercooling might play a critical role in the shelf salt budget and sea ice production”
