The Private Library of Eric Blair
Today is often labeled as the Information Age. Twenty-four hours a day, seven days a week, we are inundated with pictures, video, sound, and text. DSL, cable, cell-phones, fax machines, satellite radio, and other technologies keep us instantly in touch with events. To be connected is to be seen as contemporary and knowledgeable.
Unfortunately, this instant access is not without risk. Much of this immediate information is unfiltered, untested, and, on occasions, suspect. The anonymous Internet expert that is quoted might no more be an expert than your next-door neighbor (in fact, that web site might just be the creation of your neighbor). Often, more effort is spent channel surging, Googling, or just chatting, rather than addressing the need for careful sorting, consideration, reflection, and thoughtful contemplation.
This series examines the power and place of the book in today\u27s digital environment. Acknowledging that the printed book is perhaps an instrument destined for obsolescence, the plates nevertheless take the viewer on a visual tour of the beauty and beguiling power of images and text found within the pages of volumes disconnected from the digital world. I am sharing the private library of one ordinary citizen.https://corescholar.libraries.wright.edu/books/1153/thumbnail.jp
A rapid transition from ice covered CO2–rich waters to a biologically mediated CO2 sink in the eastern Weddell Gyre
Circumpolar Deep Water (CDW), locally called Warm Deep Water (WDW), enters the Weddell Gyre in the southeast, roughly at 25° E to 30° E. In December 2002 and January 2003 we studied the effect of entrainment of WDW on the fugacity of carbon dioxide (fCO2) and dissolved inorganic carbon (DIC) in Weddell Sea surface waters. Ultimately the fCO2 difference across the sea surface drives air-sea fluxes of CO2. Deep CTD sections and surface transects of fCO2 were made along the Prime Meridian, a northwest-southeast section, and along 17° E to 23° E during cruise ANT XX/2 on FS Polarstern. Upward movement and entrainment of WDW into the winter mixed layer had significantly increased DIC and fCO2 below the sea ice along 0° W and 17° E to 23° E, notably in the southern Weddell Gyre. Nonetheless, the ice cover largely prevented outgassing of CO2 to the atmosphere. During and upon melting of the ice, biological activity rapidly reduced surface water fCO2 by up to 100 µatm, thus creating a sink for atmospheric CO2. Despite the tendency of the surfacing WDW to cause CO2 supersaturation, the Weddell Gyre may well be a CO2 sink on an annual basis due to this effective mechanism involving ice cover and ensuing biological fCO2 reduction. Dissolution of calcium carbonate (CaCO3) in melting sea ice may play a minor role in this rapid reduction of surface water fCO2

Reply to ‘Challenging the hypothesis of an arctic ocean lake during recent glacial episodes’ by Hillaire‐Marcel, et al
Hillaire‐Marcelet al. bring forward several physical and geochemical arguments against our finding of an Arctic glaciolacustrine system in the past. In brief, we find that a physical approach to further test our hypothesis should additionally consider the actual bathymetry of the Greenland–Scotland Ridge (GSR), the density maximum of freshwater at 3–4°C, the sensible heat flux from rivers, and the actual volumes that are being mixed and advected. Their geochemical considerations acknowledge our original argument, but they also add a number of assumptions that are neither required to explain the observations, nor do they correspond to the lithology of the sediments. Rather than being additive in nature, their arguments of high particle flux, low particle flux, export of 230Th and accumulation of 230Th, are mutually exclusive. We first address the arguments above, before commenting on some misunderstandings of our original claim in their contribution, especially regarding our dating approach
Long-lived Ra isotopes by counting or by mass spectrometry: What’s the better method?
The radium isotopes 226Ra and 228Ra have traditionally been determined by counting methods, mostly by gamma counting, or via their shorter-lived daughter isotopes. With increasing sensitivity of mass spectrometers, in particular ICP-MS, attempts have been made to measure 226Ra and 228Ra via mass spectrometry. While the more abundant (in terms of atoms) 226Ra is relatively well established and several datasets have been published, only a few analyses have been published for 228Ra. ICP-MS methods, if fully developed, promise improved precision and therefore an extended applicability of radium isotopes. However, there are still a number of unresolved issues that prevent mass spectrometric techniques from being used more widely.
Complications often arise from (1) pre-concentration methods, often including manganese dioxide, and strontium or barium salts. (2) Separation of adsorbers and carriers from the Ra-containing solution (3) Availability of a 228Ra-spike for isotope dilution methods and (d) Sensitivity of the mass spectrometer, which also needs to allow controlling possible interferences.
Here I will give an overview of the pros cons of counting vs. mass spectrometry, and discuss possible ways to address some of the key problems for radium measurements via ICP-MS
Water Being Water
IQ. DNA. MRI. FYI. In an ever-changing world, we find ourselves conversing with abbreviated acronyms and phrases. They drive today\u27s economy, political agenda, and water cooler chitchat. They define our use of resources and the attention given to matters. Who we are, or think we are, are wrapped around their brevity. In our hurried attempt to sort through the complexities of life we use them to only answer the obvious-How? Unfortunately, an equally important question, Why? is often ignored. The solving of the how of things has generally been left to the scientists and the reasons as to the why for artists to decipher. This publication and exhibition takes a new approach by making the two questions inseparable. Using the simplest of elements, H20, a scientist turned artist, and two writers, one from the sciences and the other from the arts, have begun a new conversation. It is a discussion that deserves our attention and participation.https://corescholar.libraries.wright.edu/restein_catalogs/1051/thumbnail.jp
