LONG RANGE DRILLING TECHNOLOGY PLAN - June 30, 2020 1.0 INTRODUCTION The U.S. Ice Drilling Program (IDP) Long Range Science Plan lays out recommended directions for U.S. ice coring and drilling science. This companion Long Range Drilling Technology Plan addresses the drills and technologies needed to successfully implement the Science Plan. Much of the equipment mentioned is already being developed or maintained by IDP as part of its inventory of NSF equipment. This plan also describes the latest development projects at IDP. Finally, this plan briefly addresses the funding allocated for its implementation. Highlights/Changes for this 2020-2030 Update: General highlights and changes: Expanded list of Recommended Technology Investments as proposed by the IDP Science Advisory Board and other community members. Many of the proposed investments focus on defining requirements for desired technology to meet emerging science goals. IDP-WI anticipates having increased capacity for this type of work in the near-term, with field work in both the Arctic and Antarctic postponed due to COVID-19. Additions: Added plans to pursue formulation of a number of IDP Science Requirements documents for new technologies. Plan to purchase additional ASIG Drill components to complete fulfillment of the original system science requirements. Plan to discuss an approach to evaluating the condition of boreholes, fluid levels over time, and bailing or removing fluid from boreholes. Deletions: None. The high priority tasks and investments identified by the IDP Science Advisory Board (SAB) are shown below as listed in the U.S. Ice Drilling Program Long Range Science Plan 2020-2030. Recommended Technology Investments The following investments in drilling technologies are expected to be needed to accomplish science goals envisioned for the next decade. Investments prioritized by time, from discussions of the IDP Science Advisory Board, include: Priority 1 (needed this year): Maintain and upgrade agile equipment in inventory, including: Hand Augers, Sidewinders, the 4” Electromechanical Drills, the 3” Electrothermal Drill, the 3.25” Badger-Eclipse Drills, the Stampfli 4 of 52 Ice Drilling Program - LONG RANGE DRILLING TECHNOLOGY PLAN - June 30, 2020 Drill, Logging Winches, the Small Hot Water Drills, the Blue Ice Drill, the Prairie Dog, the Agile Sub-Ice Geological Drill (ASIG), the Rapid Air Movement Drill (RAM) Drill, and the Winkie Drill. Implement Foro 400 Drill system modifications following the recent first deployment of the system. Finish fabrication of a second ice-ready Winkie Drill. Develop the IDP Conceptual Design for clean sample acquisition from a hot water ice coring drill for sediment-laden basal ice samples. Develop the IDP Conceptual Design for retrieving rock, basal ice, sediment, and water from West Antarctic (e.g., Mt. Resnik) and East Antarctic sites (e.g., within Wilkes Basin) (consider suite of existing or new drills, e.g. large hole with hot water drill, then deploy sediment core or rock core, retrieve basal ice) Develop IDP Science Requirements for collecting a small amount (e.g. chips or up to 10 cm) of sub-ice rock using a lightweight tethered ice core drill, for example the Eclipse and Stampfli drills.

  • In the Autumn 2011 Edition of the Quiver I Wrote an Article Touching on the Topic of Survival As It Applies to the Bowhunter
    In the Autumn 2011 edition of The Quiver I wrote an article touching on the topic of survival as it applies to the bowhunter. In this article I want to talk about fire specifically and the different types of firestarters and techniques available. Fire is an important element in a survival situation as it provides heat for warmth, drying clothes or cooking as well as a psychological boost and if you’re hunting in a spot where you are one of the prey species it can keep predators away as well. There are many ways to start a fire; some ways relatively easy and some that would only be used as a last resort. There are pros and cons to most of these techniques. The most obvious tool for starting a fire is a match. While this is a great way to start a fire in your fireplace or fire pit I personally don’t like to carry matches in my pack or on my person. They are hard to keep dry and you are limited to one fire per match IF you can light a one match fire every time. It would be easy to run out of matches in a hurry as you are limited in how many you could reasonably carry. A Bic lighter or one of the more expensive windproof lighters is a slightly better choice for the bowhunter to carry. They are easy to use, easy to carry, fairly compact, and last for a reasonable amount of “lights”. They don’t work well when wet but can be dried out fairly easily.

  • Low-Impact Living Initiative
    firecraft what is it? It's starting and managing fire, which requires fuel, oxygen and ignition. The more natural methods usually progress from a spark to an ember to a flame in fine, dry material (tinder), to small, thin pieces of wood (kindling) and then to firewood. Early humans collected embers from forest fires, lightning strikes and even volcanic activity. Archaeological evidence puts the first use of fire between 200-400,000 years ago – a time that corresponds to a change in human physique consistent with food being cooked - e.g. smaller stomachs and jaws. The first evidence of people starting fires is from around 10,000 years ago. Here are some ways to start a fire. Friction: rubbing things together to create friction Sitting around a fire has been a relaxing, that generates heat and produces embers. An comforting and community-building activity for example is a bow-drill, but any kind of friction will many millennia. work – e.g. a fire-plough, involving a hardwood stick moving in a groove in a piece of softwood. what are the benefits?

For example, flint creates sparks - tiny shards of hot steel. strikers, fire pistons or lenses don’t need fossil Compression: fire pistons are little cylinders fuels or phosphorus, which require the highly- containing a small amount of tinder, with a piston destructive oil and chemical industries, and that is pushed hard into the cylinder to compress friction methods don’t require the mining, factories the air in it, which raises pressure and and roads required to manufacture anything at all.

  • August 2015 the LEARNING CIRCLE: NOTES, THOUGHTS & PROJECTS
    EARTH SKILLS NEWS www.earthskills.com © Jim Lowery August 2015 THE LEARNING CIRCLE: NOTES, THOUGHTS & PROJECTS I. Improve your bow drill firemaking Have you struggled with getting a bow drill fire consistently? Do you wonder what’s wrong with your apparatus or technique? Would you like to be able to try some more advanced tricks that will make firemaking easier for you? The bow drill is, in my view, the most practical of all the primitive firemaking techniques. You can get fire with many kinds of woods in many habitats, without bringing anything with you—even cordage or a knife. The hand drill is simpler, but in most locations only two or three woods at most can be used for the hand drill and hearth, and that only using very well practiced technique and strength. However I have made bow drill fires with 28 woods in my area. When we teach bow drill firemaking in our classes, we stress that mastering the technique is the most important factor. Many students, both men and women, need practice and especially the wrist and arm strength that goes with it, but if the technique is correct, success will come with time and practice. On the other hand, bad habits die slowly and so in this article I want to offer some trouble-shooting, a few reminders based on the mistakes we see most commonly with students, and some more advanced tips. (A review of the bow drill apparatus and technique can be found in your notes from our Wilderness Skills class, in Tom Brown, Jr.’s Field Guide to Wilderness Survival, and Larry Dean Olson’s Outdoor Survival Skills.

  • ICE SHELF MELT RATES and 3D IMAGING by Cameron Scott Lewis Submitted to the Graduate Degree Program in Electrical Engineering An
    ICE SHELF MELT RATES AND 3D IMAGING By ©2015 Cameron Scott Lewis Submitted to the graduate degree program in Electrical Engineering and Computer Science and the Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the degree of Doctor of Philosophy. _____________________________________ Chairperson: Prasad Gogineni _____________________________________ Chris Allen _____________________________________ Carl Leuschen _____________________________________ Fernando Rodriguez-Morales _____________________________________ Rick Hale Date Defended: May 8, 2015 This Dissertation Committee for Cameron Lewis certifies that this is the approved version of the following dissertation: Ice Shelf Melt Rates and 3D Imaging _____________________________________ Chairperson: Prasad Gogineni Date Approved: ii Abstract Ice shelves are sensitive indicators of climate change and play a critical role in the stability of ice sheets and oceanic currents. Basal melting of ice shelves plays an important role in both the mass balance of the ice sheet and the global climate system. Airborne- and satellite-based remote sensing systems can perform thickness measurements of ice shelves. Time-separated repeat flight tracks over ice shelves of interest generate data sets that can be used to derive basal melt rates using traditional glaciological techniques. Many previous melt rate studies have relied on surface elevation data gathered by airborne- and satellite-based altimeters. These systems infer melt rates by assuming hydrostatic equilibrium, an assumption that may not be accurate, especially near an ice-shelf’s grounding line. Moderate bandwidth, VHF, ice-penetrating radar has been used to measure ice-shelf profiles with relatively coarse resolution. This study presents the application of an ultra-wide bandwidth (UWB), UHF, ice-penetrating radar to obtain finer resolution data on the ice shelves.

  • We Thank the Reviewers for Their Helpful Feedback, Which Has Improved Our Manuscript. in the Interactive Discussion, We Have Replied to Each Reviewer Directly
    Dear Dr. Stroeven (editor), We thank the reviewers for their helpful feedback, which has improved our manuscript. In the Interactive Discussion, we have replied to each Reviewer directly. Below are copies of the Reviewers' comments and our responses as well as the revised manuscript with changes tracked. We would also like to bring to your attention the fact that we have made some changes to the manuscript regarding issues that were not raised by the Review- ers. These changes are described below. In the last paragraph of Section 5.3, we have changed the sentence which read \Circulation of drilling fluid in the RB-1 borehole hydrofractured the basal ice...". The new sentence reads \An unexplained hydrofracture of the basal ice of the RB-1 borehole...". After our initial manuscript submission, we realized that the present-day ground- ing line in our ice-sheet simulation was located upstream of Robin Subglacial Basin in the Weddell Sea sector of the WAIS (compare to Fig. 1). This misfit affects the plots in Fig. 2e-s because, at sites upstream of this area, thinning during interglacial periods is underestimated and thickening during glacial pe- riods is overestimated. To address this, we have taken the following actions. (i) We have added a figure (Fig. 3 in the revised manuscript) showing the misfit between the modeled and the observed present-day ice sheet. This figure shows that the model does reasonably well in most areas, but very poorly in the region of Robin Subglacial Basin. (ii) We added a paragraph to the end of Section 3 explaining this misfit and its consequences.

The Pirrit Hills granite exhibits significant negative Eu anomalies (Eu/Eu* = 0.01~0.25) and a REE tetrad effect indicating intensive magmatic differentiation. Whole-rock Rb-Sr and Sm-Nd geochronologic analysis of the Pirrit Hills granite gave respective ages of 172.8 ± 2.4 Ma with initial 87Sr/86Sr = 0.7065 ± 0.0087 Ma and 169 ± 12 Ma with initial 144Nd/143Nd = 0.512207 ± 0.000017. The isotopic ratio data indicate that the Pirrit Hills granite formed by the remelting of Mesoproterozoic mantle- derived crustal materials. Both chondrite-normalized REE patterns and Sr-Nd isotopic data indicate that the Pirrit Hills granite has geochemical features of chondrite-normalized REE patterns indicating that REE tetrad effects and negative Eu anomalies in the highly fractionated granites were produced Citation: Lee, H.M.; Lee, S.-G.; Kim, from magmatic differentiation under the magmatic-hydrothermal transition system.

  • Exposure History of West Antarctic Nunataks
    Exposure history of West Antarctic nunataks Perry Spector, John Stone, Howard Conway, Dale Winebrenner Department of Earth and Space Science University of Washington Cameron Lewis, John Paden, Prasad Gogineni Center for Remote Sensing of Ice Sheets University of Kansas There is strong evidence that the West Antarctic Ice Sheet has been thinner during the Pleistocene, however the timing, duration, and magnitude of past deglaciations are poorly known. Ice-sheet elevation changes over glacial and interglacial periods can be revealed by cosmogenic-nuclide measurements of bedrock surfaces. Whether ice was thinner during past warm climates can be tested by measuring cosmogenic nuclides in currently subglacial bedrock surfaces, provided that cold-based ice has protected the surfaces from erosion. During 2012-13, we visited three groups of small nunataks in West Antarctica with the intention of locating favorable drilling sites for the recovery of subglacial bedrock to look for evidence of thinner ice in the past. We traveled to the Whitmore Mountains, located near the ice-sheet divide, and the Pirrit and Nash Hills, nunatak groups located in the Weddell sector of West Antarctica at ~1300 and ~1500 m, respectively. At the Pirrit Hills, fresh glacial erratics are evidence of thicker ice during the last ice age and indicate that ice levels were at least ~350 m, but less than ~510 m, above the present level. Despite thicker ice, bedrock at all three sites, extending down to the present ice level, is weathered and exhibits delicate cavernous forms, evidence of prolonged subaerial weathering prior to the last ice age. The preservation of these features, along with the lack of evidence for wet-based glacial erosion, indicates that former ice cover was cold-based and protected the underlying bedrock.
