His research this summer took him on two northern expeditions, first above the Arctic Circle near Spitsbergen, Norway, followed by three weeks on a sailboat in Canadas North.</p> <p>His mission? Trying to collect samples of coralline algae, a rock-like organism that grows in shallow waters on the ocean floor. The algae has a distinctive calcium carbonate skeleton which, like trees, forms annual rings, growing upwards at one layer per year.</p> <p>Locked into that layer is important climate information, Halfar says. I can see annual cycles of temperature and get information about water temperatures over a hundred years ago.&nbsp;</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2349 img__view_mode__media_original attr__format__media_original" height="500" src="/sites/default/files/2016-10-28-utm-arctic2-embed.jpg" typeof="foaf:Image" width="750" loading="lazy"><br> <em>The&nbsp;research ship surrounded by sea ice as it sails to Norway&nbsp;</em></p> <p>The algae also sheds light on sea ice coverage over time.</p> <p>In a stable environment, these algae can grow for centuries. They need light to grow, so if there is a buildup of ice and snow on the surface, no light will penetrate and the algae will go dormant, he says. I am looking for periods of growth and dormancy that can tell us about how long sea ice occurred over a winter.</p> <p>Halfars first expedition consisted of three weeks aboard the Maria S. Merian, a research vessel with 15 scientists who were collecting data for various projects. Leaving from Reykjavik, Iceland, the ship sailed north, arriving near Spitsbergen, about 1,300 kilometers from the North Pole.</p> <p>Halfars samples are typically collected by scuba divers who use a chisel and hammer to prise the algae from the rocks. The algae can be found as far south as Maine. But&nbsp;the location of Halfars Norwegian samples the northern-most specimens ever collected presented a special challenge.</p> <p>To collect the Spitsbergen samples, Halfar took a three-hour trip below the icy ocean surface in a two-person submersible equipped with an arm to scoop up algae. Halfar collaborated with former postdoctoral student <strong>Steffen Hetzinger</strong>, now with the Helmholtz Centre for Ocean Research Kiel in Germany, to collect and analyze samples.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2350 img__view_mode__media_original attr__format__media_original" height="563" src="/sites/default/files/2016-10-28-utm-arctic3-embed.jpg" typeof="foaf:Image" width="750" loading="lazy"><br> <em>91勛圖 researcher Jochen Halfar in a two-person submarine as he studies coralline algae specimens in the Arctic</em></p> <p>Following his Spitsbergen adventure, Halfar flew to Greenland, where he embarked on the next leg of the journey aboard the Vagabond, a 15-meter chartered sailboat that would be home for the next three weeks. Halfar shared cramped quarters with&nbsp;the Vagabonds captain and his family and a four-person film crew from the German-French network ARTE, who are producing a documentary about Halfars research that will air in January 2017.</p> <p>A three-day sea voyage took Halfar from Greenland to Canada where the team sailed around the northern coast of Baffin Island, eventually tracing a route across Lancaster Sound to Resolute Bay and around the smaller islands. After Halfar left, graduate student <strong>Alicia Hou</strong> continued the research, travelling through the Gulf of Boothia to Goose Bay, Labrador.</p> <p>Im trying to collect longer-term records going back several hundred years over as wide an area as possible, Halfar says. I have to cover a wide geographic area to create this network.</p> <p>Thanks to satellite technology, we know how the ice has retreated over the last 40 years but we dont know what happened before that, Halfar says. We are trying to get a long-term picture of how sea ice has behaved over the years and before the time of human influence, like the Industrial Revolution. With the algae, I can reconstruct that information.</p> <p>Halfars specimen haul amounted to about 80 kilograms&nbsp;of samples, which will undergo geochemical analysis. The data will provide clues about climate in past centuries and help predict what might happen in the future, too.</p> <p>That data can be used by climate physicists to create models that project climate into the future, Halfar says. If we understand the past better, we can predict the future of the ice in the Arctic.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2351 img__view_mode__media_original attr__format__media_original" height="498" src="/sites/default/files/2016-10-28-utm-arctic4-embed.jpg" typeof="foaf:Image" width="750" loading="lazy"><br> <em>Jochen Halfar and former postdoctoral student Steffen Hetzinger with coralline algae specimens collected at 80繙 North, near Spitsbergen.</em></p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 28 Oct 2016 16:03:22 +0000 ullahnor 101780 at Polanyi Prize awarded to Barbara Sherwood Lollar /news/polanyi-prize-awarded-barbara-sherwood-lollar <span class="field field--name-title field--type-string field--label-hidden">Polanyi Prize awarded to Barbara Sherwood Lollar </span> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>sgupta</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2016-02-16T05:02:53-05:00" title="Tuesday, February 16, 2016 - 05:02" class="datetime">Tue, 02/16/2016 - 05:02</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Might life really exist, or have existed, on Mars?

Theres more oil on the market right now than we actually need. Up until the 1970s, oil prices were very stable and quite low&nbsp;&nbsp;in the range of $10 to $15 a barrel. The oil markets back then were completely dominated by large oil companies like Exxon, Shell, British Petroleum, Chevron. Then in 1973-1974, there was the Yom Kippur war in the Middle East between Israel and its Arab neighbours. The United States offered unquestioning support and assistance to Israel, making the Middle Eastern countries very angry and the Organization of Petroleum Exporting Countries (OPEC) members decided to limit supply to the West to seek revenge. The price shot up. It was a limited supply, and in the United States, gas stations literally ran out of oil. The oil market has never been the same since.&nbsp;</p> <p>OPEC has managed to control supply since then, but their power over the markets has become diminished in recent years largely because of the appearance of a large supply from other areas. The North Sea, for example, became a big player in the 1980s and 1990s. Russia also became a big supplier. In recent years, the United States has become one of the worlds leading oil producers after many years of being considered to have exhausted all its oil fields. This is because of new technologies that can liberate oil from very unpromising formations, known as fracking.&nbsp;</p> <p>So the United States has become one of the largest producers of oil, and OPEC countries, Saudi Arabia in particular, have been very concerned because theyve seen not only the price dropping, but realize they could lose their market share. So they made a strategic decision to not reduce their own output, which meant the oversupply increased dramatically. When you have a massive oversupply of any commodity on the market, the price will drop. Weve had a steady drop in price from a high of about $140 a barrel in June 2008, to now around the $30 range.</p> <p><strong><img alt="photo of colourful oil barrels" src="/sites/default/files/2016-02-04-oil-barrels.jpg" style="width: 159px; height: 240px; margin: 10px; float: right;">Actual barrels are no longer a thing</strong><br> The barrel is used as a convenient measure because in the old days thats really how oil was transported. The actual calculation is 1 barrel equals 44 Imperial gallons (in the UK), 53 U.S. gallons, or 200 L.&nbsp;</p> <p>(<a href="https://www.flickr.com/photos/magnera/3755006104/in/photolist-6HPouy-9Twmw8-8dhgGv-ifTcMa-6XGAK9-7EXyv-4Ze4ea-btXVa8-aQQGVZ-8Tqmzz-ifTcJK-sPyJKR-4N1oMe-cjFdbW-fbmtHY-boPXcw-bsv7CV-pdLJdD-aCmeaq-4VcFAD-8gggMF-9BL43Z-apPrfU-73PXSP-rqS15K-6YEu2c-dVU8h8-6Phdq7-qLwkpt-4ECoaH-7VPjCG-aV1yyX-8ggf8F-8grCWG-8girrB-8gp2Gp-8gs4NC-8gr2TC-8gq6wK-8gnuZS-8gnc8o-8gmyhb-8gsNLY-8gkzkh-8gokbM-8gsDGf-8gqD4W-8gnPPf-8gjm1t-8gsHY7">photo by L.C. N繪ttaasen via flickr</a>)</p> <p><strong>Crude oil and gasoline are not the same</strong><br> Crude oil comes out of the ground and varies tremendously in viscosity. It can be a light liquid or it can be a much thicker liquid, so thick that it doesnt flow off the rocks at all. Thats what the oil sands are. The alternative name for oil sands is tar sands because it just sticks to the sand. Thats why it needs these industrial processes to release the oil from the sand. Gasoline refers to the light, low viscosity oil that is a product of refining that is used as a fuel for motorcars. Fossil fuels is a general term for oil, natural gas and coal. Fossil fuels are products of decay of organic material in sedimentary rocks over a long geologic time period. They provide 80 to 85 per cent of the worlds energy needs. Globally we use 90 million barrels of oil every day. Thats a heck of a lot of energy.&nbsp;</p> <p><strong>A drop in the price of oil does not mean&nbsp;gas prices go&nbsp;down</strong><br> The gasoline price is going down but it is not going down as much as people would like. It has a lot to do with the costs of refining, transporting and marketing, which has not changed. A lot of whats done in the industry depends on imports from the United States, which of course has to be paid for in US dollars. That means theyre more expensive. So we cannot expect the price of gasoline at the pump to fully reflect the changing price of crude oil on the world market. Its never going to do that exactly.&nbsp;</p> <p><strong>Pipelines are controversial but mostly safe</strong><br> For a very long time, Canada was providing a very large proportion of the imported oil that the United States was using. Around the 1970s, the United States did not produce enough oil domestically to satisfy its own needs. So it started to import it. Canada provided about a quarter of the oil that the United States was importing. The North American oil for a very long time worked as if it was a seamless continental industry, with production, refinery, pipeline and delivery all managed as if the Canada-U.S. border did not exist.</p> <p>For example, weve long been exporting oil and natural gas from Alberta to the United States through pipelines across the border in the West, from Alberta to Montana for example. The East Coast oil from Hibernia off Newfoundland is largely exported to eastern United States for refining there, and then re-imported back into Canada in the form of usable domestic refined products like gasoline. So theres a tremendous amount of cross border trade thats been going on for a long time. It was considered a quite natural proposal to build a pipeline from Alberta into the United States for the delivery of crude oil from the oil sands to refineries in Oklahoma. &nbsp;&nbsp;</p> <p>That was the origin of the Keystone Pipeline proposal. But this proposal came at a time when there was heightened concern about use of fossil fuels and its effect on greenhouse gas emissions. Environmental concerns began to affect the progress of the continental oil industry. Keystone became a standard bearer for environmentalists in their determination to slow down if not end the oil industry completely in the interest of reducing greenhouse gas emissions.</p> <p><img alt="photo of Keystone" src="/sites/default/files/2016-02-04-keystone-flickr.jpg" style="width: 640px; height: 259px; margin: 10px;">(<a href="https://www.flickr.com/photos/shannonpatrick17/8480337530/in/photolist-dVnWU3-dDaXmh-4dJLmX-rrwcfU-4DZov3-ogvPnb-qFUErS-8rrDBk-9xXjY-hHmnUU-t8Z1dx-9fzeNf-oewxtL-dVnX4W-rpVa5N-b5yjev-h93mzS-DfSmD-hyaTSf-5Yiy99-5gYUWg-k3ZHvR-aCyoBm-aCvEi2-7K7uSZ-qKRPzu-4scuyw-81fSdB-bmVqvm-8paNG7-4jC5me-8m4qHa-4wd7Ge-jczYL-r3rFa6-q6BU3B-eHEhrt-nzMXYB-pPnFHi-5fq7Qu-8m4qH6-fjrWva-f76JUK-srkJXE-nnuTLC-faksxt-fjrWcD-5fkJXp-aCyn9s-bCYMag">Photo of Keystone by Shannon Ramos via&nbsp;flickr</a>)&nbsp;</p> <p>Theres something like 100,000 km worth of pipelines, crisscrossing Canada right now, carrying all kinds of oils and fuels. There are a number of big pipeline proposals on the table for Canada for a few years now. Besides Keystone, theres also the Northern Gateway pipeline proposal to deliver oil from Alberta to Kitimat on the west coast of British Columbia. Therere several others. Some are not receiving final approval because of Aboriginal concerns, environmental concerns and concerns about increased tanker traffic along the British Columbia coastline.</p> <p>The last project that looked like it would have the least problems was the Canada East proposal, which was designed to convert an existing pipeline from Alberta to Ontario. Its an entirely Canadian route, to convert it from gas to oil and to tie it into an existing pipeline that crosses part of Ontario, and build a new pipeline through Quebec that would then extend that line to St. John, New Brunswick. Montreal mayor Denis Coderre has legitimate concerns about pipeline leaks, about pollution of groundwater. By and large pipelines are extremely safe. The alternative is transport by rail and you only have to say words Lac-M矇gantic to know what transporting oil by rail can lead to.</p> <p><strong>Fossil fuels are everywhere</strong><br> There is a very strong concern about climate change that fossil fuels are one of the major contributors to greenhouse gas emissions, and therefore we should start to transition away from the use of fossil fuels to other sources of energy.&nbsp;</p> <p>One of the things that I think is not fully understood in Canada not only is the oil and gas industry a very important part of our economy in terms of jobs and earnings, it also provides this essential part of the energy supply that we cannot live without. Right now there are no alternatives to the use of oil and natural gas on a large scale. Things like air transport. Oil from the ground is refined for lubricating oil, grease. Its not widely understood that virtually all of our synthetic materials plastics, resins, synthetic material used in furniture and clothing they all come from petroleum. These are what are called petrochemical products.</p> <p>The plastics industry would not exist without petroleum. So the idea that we can shut down this fossil fuel industry and replace it with wind power, solar panels and biofuels is not yet possible. Its much too early to be talking about shutting down the fossil fuel industry. We simply do not have the alternative technology in place yet to allow us to do that. This means the oil industry needs its infrastructure. It desperately needs these pipelines.</p> <p>The new Trudeau government has to find a way to make this possible by working hard to develop what Justin Trudeau has called the social license the general widespread public acceptance of the need for this pipeline. He has to satisfy the public that the legitimate environmental concerns are being taken care of, that aboriginal rights are respected, that procedures are in place to properly manage pipeline breaks, and that companies are behaving responsibly.</p> <p>Until all of that is done, then we will not be able to build any major pipeline. They are essential to the further progress of the Canadian economy.
