title: CTD and Optical Data from the Ice-Tethered Winch Deployment Trial Spring 2014

description: These data were collected as part of a development project that merged two existing technologies: the ice-tethered profiler and the arctic winch. The new platform, the ice-tethered winch, combines the capabilities of these two platforms, providing near real-time data, similar to the ice-tethered profiler, but capable of profiling over the variable topography of the shelf (arctic winch). The surface package for the ITW is based on that of the ITP with Iridium, GPS, electronics, and power for communications, and buoyancy sufficient to float the system in open water. The lowered package is based on the Arctic Winch and includes the electronics, power, and hardware for a sub-surface winch and winch controller along with an instrumentation package that is repeatedly lowered and raised from its docking station beneath the ice to the bottom or 50-m depth, whichever is less. Sensors measure conductivity, temperature, pressure, fluorescence, and turbidity. Year two of the project included finalization of the design, manufacture of the systems and field-testing. In spring 2014, two ITWs were temporarily deployed offshore of Barrow, AK as part of the testing phase of the system.. ITW1 was deployed at 71.3956N, 156.4879W and ITW2 was deployed at 71.3961N, 156.4882W. The deployment spanned April 2014. The CTD and optical (fluorescence and turbidity) data from this test period in shallow water (~5-m depth) are available here and from the ITP website (www.whoi.edu/itp/itw1data.html, www.whoi.edu/itp/itw2data.html). The project website has links to the data as well as more information about the development (www-highlat.coas.oregonstate.edu/~highlat/ITWSite).

title: Snowpack gas concentrations, Toolik Lake, Alaska, 2011-2016

description: Atmospheric surface ozone (O3) was measured at Toolik Lake, Alaska, from September 2010 to August 2011, along with winter and springtime (January–May) measurements of gaseous elemental mercury (GEM). Air-snow exchange fluxes of O3 and NOx (NO+NO2) were measured to capture effects of changing insulation, and snowpack properties at Toolik. Measurements include O3, GEM, and NOx levels and gradients both within and above the snowpack and eddy-correlation O3 fluxes at two heights above the snowpack; ancillary measurements characterized atmospheric turbulence, actinic flux, micrometeorological parameters and the snowpack's physical and radiative properties. GEM measurements, along with snowpack O3 and NOx were used to characterize and compare ozone depletion events at Toolik Lake and Barrow, Alaska. Ongoing measurements of surface O3 and meteorological parameters began in September 2014.

title: Snowpack gas concentrations, Summit, Greenland, 2008-2010

description: Air-snow exchange fluxes of ozone(O3) and NOx (NO+NO2) were measured at Summit, Greenland, to capture effects of changing insulation, snowpack properties. The study site included a buried laboratory facility, snow-sampling manifold, and a meteorological tower installed in the clean air sector ∼650 m southwest of the main camp structures. A multi-inlet snow sampling manifold (‘snow tower’) for measuring trace gases at multiple depths in interstitial air was constructed for use in this study. Pairs of sampling inlets were located on each cross arm on the tower; cross arms were rotated orthogonally to the arms above and below. Flow rates were 1.2–2.5 L per min and were split between the inlet pairs, producing effective flow rates of 0.6–1.25 L per min through each inlet. Sample inlets were fitted with 25 mm Acrodisc® hydrophobic polytetrafluoroethylene (PTFE) syringe filters (Pall Life Sciences, Ann Arbor, Michigan, USA). Inlet pairs were connected via a Teflon perfluoroalkoxy (PFA) union tee to a 30 m × 0.64 cm OD (0.40 cm ID) Teflon PFA sampling line. Measurements include O3, gaseous elemental mercury (GEM), and NOx levels and gradients both within and above the snowpack and eddy-correlation O3 fluxes at two heights above the snowpack; ancillary measurements characterized atmospheric turbulence, actinic flux, micrometeorological parameters and the snowpack's physical and radiative properties.

title: Studies of the Production of Molecular Halogens in Arctic Snowpacks and on Sea Ice Surfaces

description: This project would involve field experiments at Barrow, AK, aimed at improving understanding of the oxidation of the sea salt halides, chloride and bromide, into the molecular halogens, clorine-Cl2, bromine monochloride-BrCl, and dibromine-Br2. In the Arctic at spring time there is a dramatic phenomenon characterized by the complete loss of ozone from the lowest layer of the atmosphere, along with near-complete loss of atmospheric elemental mercury. The elemental mercury is oxidized to short-lived products that then deposit to the surface, where it can enter and damage sensitive ecosystems. These ozone depletion episodes (ODEs) and mercury depletion episodes (MDEs) are known to occur as a result of halogen atom chemistry. However, the details of the halogen reactions that lead to the ODEs and MDEs are still unknown, limiting the ability to develop models that describe these processes, and how they might change in the future. It is thought that the processes that release molecular halogens are related to the presence of seasonal, or first-year (relatively thin and relatively saline), sea ice. The Arctic is currently experiencing a rapid decrease in the extent of multi-year sea ice, with associated increases in the extent of first-year sea ice. Thus the investigator hypothesizes that this halogen chemistry, and the associated potential impacts on atmospheric composition and deposition of mercury, will increase to the extent that the current trend in sea ice loss continues. To improve understanding of the fundamental processes associated with the production of molecular halogens in the Arctic, the investigator proposes an experiment involving exposures of natural snow samples and excised sea-ice samples in a snow chamber to potentially important atmospheric oxidants and measurement of the product molecular halogens. The investigator would also simultaneously conduct measurements of the concentrations of these compounds within the natural snowpack. He would then construct a detailed photochemical model of the chemistry involved with ODEs and MDEs, that could then be incorporated into larger scale Earth System climate and chemistry models to help enable reliable simulations of the future state of the Arctic atmosphere. The project would support a postdoctoral researcher and a graduate student. Numerous outreach activities would be supported through the Purdue Climate Change Research Center, interactions with the local community in Barrow, visits to schools, and through collaboration with adventure and children's book writer Peter Lourie on the web site arcticstories.net.

title: Trace inorganic species measured above and in the snowpack in Barrow, AK 2014

description: This work was conducted by Purdue University. We measured iodine-I2, dibromine-Br2, clorine-Cl2, bromine monochloride-BrCl, and ozone-O3 concentrations above the snowpack along within the snowpack interstitial air during Jan. and Feb. of 2014 in Barrow, Alaska. Inorganic halogen measurements were performed using a chemical ionization mass spectrometer. This field deployment was performed to study the production of molecular halogens with the Arctic snowpack.

title: Toward Developing an Arctic Observing Network: An Array of Surface Buoys to Sample Turbulent Ocean Heat and Salt Fluxes During the IPY

description: This project will deploy ocean flux buoys in the Arctic ocean as part of a group effort to contribute to the goals of the IPY and the Study of Environmental Arctic Change (SEARCH) project by: (1) implementing automated monitoring of oceanic fluxes that, along with their atmospheric counterparts, determine the thermodynamic balance of sea ice at a time of significant change in ice volume and extent. It is this balance, considered throughout the basin, that will determine if the Arctic transitions to a state of greatly reduced or no perennial ice cover, (2) contributing to a database of repeated drift trajectories and upper ocean current structure from the Eurasian Basin across the marginal ice zone, (3) working to improve formulations of ocean surface fluxes for use in large scale models, (4) investigating the effects on ocean surface heat flux of variability in heat transport through Fram and Bering Straits, (5) contributing data that will be used to design optimal observing networks. The overall objective of this portion of the project is to measure and understand the role of the upper ocean in the thermodynamic balance of sea ice within the context of the environmental changes underway in the Arctic.

title: Autonomous Ocean Flux Buoy (AOFB) 15 time series data, Arctic Ocean, 2008

description: Time-series data from the Naval Postgraduate School (NPS) Autonomous Ocean Flux Buoy (AOFB) #15. This buoy was deployed at the 2008 North Pole Environmental Observatory (NPEO) ice camp 8 April 2008. The buoy drifted across the Eurasian Basins and exited the Arctic Ocean through Fram Strait. The time series ended on 30 December 2008. The buoy measured velocity, temperature, salinity, and the vertical turbulent fluxes of heat, salt, and momentum in the ocean surface mixed layer with a custom-built sensor package about 5 m below the ice-ocean interface. The buoy also measured vertical profiles of ocean currents with an RD instruments 600 kHz Acoustic Doppler Current Profiler (ADCP). AOFB 15 entered open water as it drifted through Fram Strait, on about 26 October 2008. Additional information about the NPS AOFB program, including real-time data from active buoys, is available at: http://www.oc.nps.edu/~stanton/fluxbuoy The flux package data set is provided in Matlab and NetCDF file formats. Velocities are reported in the instrument coordinate system of the flux package acoustic travel-time current meter. The fluctuation kinetic energy variable is useful for identifying time periods when the buoy is in open water and flux estimates are contaminated by surface-wave motions.

title: Community Elder Interviews

description: Semi-structured interviews with Community Elders regarding: 1) The environmental and social changes they have already observed in their lifetimes and their hopes and fears for the future in the context of incoming industrial development and the potential for more environmental and social changes to come (both positive and negative). 2) Whether or not they felt that their community was currently in the best position possible to both take advantage of the opportunities as well as face the challenges that such change could represent and whether they had any suggestions for improvements in terms of local decision-making processes, etc. 3) About the knowledge and practices they felt were most needed to be documented and communicated to outside decision-makers. Participants were also asked to identify some of the cultural values and traditional practices that they felt were critically important to pass on to the youth within their own Tribe. 4) Overall, what they felt was the most important thing that their community could do to embrace the changes to come while still maintaining the core values of their culture. Emphasis in these interviews were put on their perspectives as knowledgeable and respected elders, especially when it came to offering their critiques and suggestions about present conditions and future courses of action for their community. The structure of the interviews was relatively loose to allow the elders to freely share their recollections from the past and to generally speak about whatever they most preferred to discuss.

title: Focus Groups with Village Residents

description: These conversations were designed to capture the feedback and perspective of community members in the context of the proposed offshore drilling program. The range of participants included groups of active hunters and whalers to young aakas [grandmothers] and small family groups. Participants were asked the same set of questions as their community Elders, although the format was more strictly adhered to in the context of these group discussions. Participants were asked: 1) About the environmental and social changes they had already observed in their lifetimes and their hopes and fears for the future in the context of incoming industrial development and the potential for more environmental and social changes to come (both positive and negative). 2) Whether or not they felt that their community was currently in the best position possible to both take advantage of the opportunities as well as face the challenges that such change could represent and whether they had any suggestions for improvements in terms of local decision-making processes, etc. 3) About the knowledge and practices they felt were most needed to be documented and communicated to outside decision-makers. Participants were also asked to identify some of the values and traditional ways of doing things here in the village that they felt were critically important to pass on to the youth within their own Tribe. 4) Overall, what they felt was the most important thing that their community could do to embrace the changes to come while still maintaining the core values of their culture.

title: Photo-elicitation Interviews on Iñupiaq Conceptualizations of Nature

description: Participants were provided with digital cameras and instructed to take photographs of anything that captured what “nature meant to them as an Iñupiaq.” These photographs were then printed out and served as an interview guide where participants were asked: 1) To first pick out the top 5 pictures that really captured what nature meant to them as an Iñupiaq. For each of these photographs, participants were then prompted to give a short descriptive title to the photo, to generally explain what was going on in the picture, to describe what they were thinking about when they took the picture, and to discuss what it was about that photograph that really captured what nature meant to them as an Iñupiaq. 2) To then organize the remaining photographs into piles based on related themes. Each thematic group of photos was then discussed in terms of what was generally going on in each photo and how the photographs were related. 3) Several follow-up questions. Participants were prompted to provide a few short words or sentences that expressed what nature meant to them. They were also asked whether they felt that non-Natives from outside the community might think about or act differently towards ‘nature’ when compared to someone from the village. Lastly, they were asked whether they had ever heard the term “the sea is our garden” used locally, and if they were familiar with that term, what it meant to them. The goal of this research activity was to explore the worldviews and relationships to the land and sea that are part of a subsistence way of life here in the village.These perspectives are often overlooked by non-Native decision-makers who try to engage with the traditional knowledge of the Iñupiat. The general argument here is that the traditional knowledge of Native peoples is often mistranslated when it is removed from its source communities because it is divorced from the very context that gives this knowledge its true meaning and power.
