Nitrate, nitrite, phosphate, dissolved silica concentrations (micromol/L) measured in the Beaufort Sea on multiple casts at 8 stations in 2009Roger Francois, Jean-Eric Tremblay & Jonathan Gagnon
The concentrations of dissolved nutrients (nitrate, nitrate, phosphate, and dissolved silica) were measured on board ship with a nutrient autoanalyzer to complement the hydrographic data. They were measured on samples collected with the Trace Metal Clean Rosette at Station L1 (71°06'N, 139°10'W), L1.5 (73°19'N, 139°23'W), L2 (74°30'N, 137°00'W, L3 (75°17'N, 137°30'W), L1.1 (72°31'N, 136°41'), and S4 (71°11'N, 132°57'W) and on samples collected with the regular ArcticNet rosette at station S1 (69°30'N, 137°59'W), S2 (70°00'N, 138°30'W),...
Partial pressure (or fugacity) of carbon dioxide, temperature, salinity and other variables collected from surface underway observations using carbon dioxide gas analyzer, shower head equilibrator and other instruments from R/V Meteor research cruise along the WOCE Section AR12/AR24 (EXPOCODE 06MT19970515) in the North Atlantic Ocean from 1997-05-15 to 1997-06-08 (NCEI Accession 0162256)Arne Körtzinger
NCEI Accession 0162256 includes Surface underway, chemical, meteorological and physical data collected from R/V Meteor research cruise along the WOCE SectionAR12/AR24 (EXPOCODE 06MT19970515) in the North Atlantic Ocean from 1997-05-15 to 1997-06-08. These data include measurements of mole fraction of CO2 in the equilibrator headspace (dry) at equilibrator temperature, mole fraction of CO2 measured in dry outside air, barometric pressure in the equilibrator headspace, water temperature in equilibrator, sea surface temperature, sea surface salinity and...

GPCC Monitoring Product: Near Real-Time Monthly Land-Surface Precipitation from Rain-Gauges based on SYNOP and CLIMAT dataUdo Schneider, Andreas Becker, Peter Finger, Anja Meyer-Christoffer, Bruno Rudolf & Markus Ziese
This is the GPCC Monitoring Product of monthly global land-surface precipitation based on the station database (SYNOP, CLIMAT) available via the Global Telecommunication System (GTS) of the World Meteorological Organization (WMO) at the time of analysis (2 months after end of an analysis month). This product contains the monthly totals on a regular latitude/longitude grid with a spatial resolution of 1.0° x 1.0° and 2.5° x 2.5°degrees. Interpolation is made on the anomalies from the...
ISIUOP undertook extensive field research corresponding to the gathering of Inuit sea ice use and knowledge data. The numerous community visits were also used for verification of data previously mapped and documented. The data we collected include: (a) a characterization of seasonal sea ice conditions; (b) the extent and areas of sea ice use; (c) the nature and location of notable sea ice hazards; (d) key harvesting areas; (e) traditional and current ice (and land)...
Data collected in semi-structured interviews. Data types include recordings, interview forms, and paper maps. Map information digitized and stored in a GIS-linked database.
Patterns of age-related water diffusion changes in human brain by concordance and discordance analysis.Yu Zhang, An-Tao Du, Satoru Hayasaka, Geon-Ho Jahng, Jennifer Hlavin, Wang Zhan, Michael W. Weiner, Norbert Schuff & Memory And Aging Center
In diffusion tensor imaging (DTI), interpreting changes in terms of fractional anisotropy (FA) and mean diffusivity or axial (D(||)) and radial (D(?)) diffusivity can be ambiguous. The main objective of this study was to gain insight into the heterogeneity of age-related diffusion changes in human brain white matter by analyzing relationships between the diffusion measures in terms of concordance and discordance instead of evaluating them separately, which is difficult to interpret. Fifty-one cognitively normal subjects...
Twenty-eight alpine ice patches were identified using a combination of remote sensing techniques, archaeological site survey methods, and traditional knowledge. These alpine patches are similar in that they are all used extensively by caribou in summer and are accessible to human hunters. Biological specimens were collected from all 28 sites using ice coring technology and surface collection and include faunal remains (mostly bones) and fecal matter. The osteological remains were used, along with modern samples,...
GPCC Climatology Version 2011 at 0.5°: Monthly Land-Surface Precipitation Climatology for Every Month and the Total Year from Rain-Gauges built on GTS-based and Historic DataAnja Meyer-Christoffer, Andreas Becker, Peter Finger, Bruno Rudolf, Udo Schneider & Markus Ziese
This is the GPCC Precipitation Climatology providing the mean monthly global land-surface precipitation for every month of the year and the annual total. It is based on the 67,200 stations world-wide that feature record durations of 10 years or longer, for the target reference period January 1951 to December 2000. However, if no station data were available for the target period, earlier or later data records of 10 years or longer are considered, yielding a...
Furo[3,4-b]chromones, and not Pyrano[3,4-b]chromones, are Obtained by the Reaction of 3-Formylchromones with IsocyanidesAna Neo, Leda Garrido, Jesús Díaz, Stefano Marcaccini & Carlos Marcos
The reaction of formylchromones with alkyl isocyanides was reinvestigated. In earlier reports from other research groups, two different structures were proposed for the products of this reaction. Herein, we provide unambiguous evidence that these products are chromenylmethylene furochromenones and not pyranochromones. Our structure assignment is based on X-ray diffraction analysis and two-dimensional NMR methods. The knowledge of the correct structure of these compounds is essential for the design of derivatives with potential applications as bioactive...
