title: North Pole Environmental Observatory (NPEO) Nutrient, Chlorophyll, and Hydrographic Profiles, Version 1.0

description: This project began an evaluation of nutrients and phytoplankton standing stocks in the central Arctic Ocean based on sampling at the North Pole Environmental Observatory (NPEO). The first sampling occurred in April 2005, the second in April 2006, where eight vertical profiles of hydrographic properties (salinity, temperature, sigma-t), in-situ fluorescence, and nutrients in the region of the NPEO were determined. Vertical profiles of hydrographic, fluorescence, and nutrients over the upper 150 m were obtained using a Sea-Bird SBE-19 CTD (serial number 1923347-2995) combined with a Wetstar model WS3S miniature flow-through fluorometer (serial number 646P), which had an excitation wavelength of 460 nm and an emission wavelength of 695 nm. The continuous CTD profiles were processed using standard SeaSoft software with the results being binned into 0.5 m depth intervals. The fluorometer was calibrated in the laboratory with aqueous solutions of resorufin (Christensen, 2006a). The fluorescence of resorufin was compared with the fluorescence of purified chlorophyll-a (from the algae Anacystis nidulans) dissolved in buffered acetone (10 ml of 1% (weight per volume) magnesium carbonate per L of 90% acetone). These chlorophyll solutions showed a fluorescence of 40.0 times that of resorufin for the same molar concentrations. The output of the fluorometer was first converted to fluorescence of resorufin (mmol/L) and then to that of chlorophyll-a (expressed in microgram-chl/L) using this factor and the molecular weight of chlorophyll-a (893.5 g/mole).

title: Leaf water potential, Feb2016-May2016, PA-SLZ, PA-PNM, PA-BCI: Panama

description: This data package contains leaf water potential data from the Barro Colorado Island (BCI), Parque Natural Metropolitano (PNM), and Bosque Protector San Lorenzo (SLZ) NGEE Tropics field sites in Panama. Pre-dawn and diurnal leaf water potential were measured on a monthly basis from February to May 2016 at SLZ and PNM. Data from BCI are only available for the month of March. This data was collected as part of the 2016 El Niño-Southern Oscillation (ENSO) campaign. Included in the attached zip file are data and metadata folders. The single data file "2016ENSO_Panama_LWP" has been provided in both Excel and CSV formats for usability purposes. The metadata file "Metadata_description_2016_ENSO_Panama" provides protocols, site descriptions, equipment information, and more, and has been provided in .docx and PDF file formats. See related datasets (existing and future) for further sample details, leaf spectra, leaf mass area (LMA), gas exchange and leaf chemistry data. VERSION 2 update. The identification of a species from the PNM site has been corrected as follows: the identification of the tree initially identified as Pseudosamanea guachapele (ALBIED) has been revised to Albizia adinocephala (ALBIAD). The updated data package includes revised data, metadata and protocol documents updated to reflect this change.

title: A Half-Century of Change in Arctic Alaskan Shrubs: A Photographic-Based Assessment, Version 1.0

description: In this study, the locations of 193 old aerial photographs of northern Alaskan landscapes were rephotographed and assessed for changes in vegetation. The original photographs were taken over northern Alaska between 1948 and 1951, and the new photographs were taken between 1999 and 2003. The region covered by the original and repeat photographs stretches from the southern extent of the Brooks Range in the south to the Coastal Plain in the north, and from the Chukchi Sea in the west to the Canning River in the east. The original photographs were taken by the U.S. military as part of geologic reconnaissance and exploration, and the method used to acquire them was to fly both sides of a river valley while photographing the river and the facing valley slopes. Of the several thousand original photographs, only a fraction were repeated for the purpose of assessing vegetation change. Repeat photographs were selected for geographic coverage and to produce the greatest likelihood of detecting vegetation change. The original and repeat photographs were then scanned and stored in TIFF format. Individual image file sizes range from 5 to 60 MB each, and the total file size for the data set is approximately 11 GB. The images should not be published without the consent of the investigators.

title: Snow Pit Data from Greenland Summit, 1989 to 1993, Version 1.0

description: Chemistry and isotope information from snow pits dug at the Summit area of Greenland, 1989-1993 includes major ions (Na, K, Mg, Ca, Cl, NO3, SO4), oxygen isotopes (18O) and H2O2. Four snow pits were dug and sampled in 1989, three snow pits in 1990, two in 1991, one in 1992 and one in 1993. All snow pits had a 3 cm sampling interval except the snow pits in 1990, which had either a 3 cm or 5 cm sampling interval. Chemistry and isotope information were obtained from each of the snow pits. The pits and surface snow samples were collected by the Glacier Research Group (GRG), using established protocols to prevent contamination. The samples collected in 1991 were analyzed at the Greenland Ice Sheet Project Two (GISP2) drilling camp. All data except the oxygen isotope data, which is from the University of Washington, were generated by GRG at the University of New Hampshire.

title: Pan-Arctic Land Surface (PALS) model drivers and outputs, Version 1.0

description: This data set includes forcing data and output fields for multimodel simulations of pan-Arctic hydrology. All models were forced with European Centre for Medium-Range Weather Forecasts (ECMWF) 40 Year Re-analysis (ERA-40) data for the period 1979-2002. The forcing fields comprise precipitation, 2-m air temperature, incoming solar and longwave radiation at the surface, 10-m winds and specific humidity at the lowest model level, the latter calculated from dewpoint, temperature and pressure. These are available every 6 h on a grid with an approximate 125 km spacing (the so-called N80 reduced Gaussian grid). Precipitation and radiation fluxes are provided as 6-h accumulations from 6-hr forecasts. Temperature, 10-m winds, pressure and dewpoint represent instantaneous values at the 6-h analysis time. The ERA-40 data on the N-80 grid were interpolated to the 100 km Equal-Area Scalable Earth grid (EASE grid) array.

title: Sedimentary Denitrification Rates from the Bering, Chukchi, and Beaufort Seas, Version 1.0

description: This data set contains the sedimentary denitrification rates from the Bering, Chukchi, and Beaufort Seas obtained during August-September 1992, and rates obtained in the Beaufort Sea off Pt. Barrow, Alaska, under late wintertime conditions (March 1993). The estimates made during August-September were based on both deployments of an automated in-situ benthic flux chamber tripod and on pore water chemical profiles from cores analyzed aboard the R/V Alpha Helix. Wintertime observations were obtained using scaled-down versions of the in-situ benthic flux chamber that were deployed through land-fast ice. The complete results are published in Devol, A.H., L.A. Codispoti, and J.P. Christensen, 1997. Summer and winter denitrification rates in western Arctic shelf sediments. Continental Shelf Research 17 (9): 1029-1050.
