Primary productivity, pulse amplitude modulated fluorometry and nutrient drawdown data from the marginal ice zone: BROKE-WEST survey 30o-80oE, 2006This data set contains primary productivity, pulse amplitude modulated fluorometry, and nutrient drawdown numbers associated with the abstract presented below. 14C Primary Productivity Gross column-integrated primary productivity determined through measurement of NaH14CO3 uptake by phytoplankton (1 hour incubations). Primary productivity was modelled from photosynthesis v irradiance curves, chloro

BOREAS TGB-12 Radon-222 Flux Data: NSAThe BOREAS TGB-12 team made measurements of soil carbon inventories, carbon concentration in soil gases, and rates of soil respiration at several sites to estimate the rates of carbon accumulation and turnover in each of the major vegetation types. Sampling strategies for soils were designed to take advantage of local fire chronosequences, so that the accumulation of carbon in new moss growth coul

BOREAS TGB-12 Radon-222 Activity Data over the NSAThe BOREAS TGB-12 team made measurements of soil carbon inventories, carbon concentration in soil gases, and rates of soil respiration at several sites to estimate the rates of carbon accumulation and turnover in each of the major vegetation types. Sampling strategies for soils were designed to take advantage of local fire chronosequences, so that the accumulation of C in regrowing mosses could be

WAIS Divide Biological Data from J. Priscu and C. Foreman, Montana State UniversityData from J. Priscu and C. Foreman, Montana State University. WAIS Divide core (WDC05Q, Stick D). Ice core samples were decontaminated following (Christner et al., 2005 Icarus, 174: 572-584) and handled in a class 100 environmental chamber. Meltwater was pre-filtered (30um) and gently sonicated prior to staining biotic particles with 5uM SYTO 60 (Invitrogen) for 5 min. Counts of biotic and abiotic

X-Ray Imaging Telescope: Balloon Data from INPE, in BrazilThis set contains 20 minutes of data obtained by 35 NaI detectors (TOTAL AREA of approx. 280 sq. cm) flown on the imaging telescope TIMAX. It is stored in 64 kbyte binary files. Each file has all the digitized spectra of each detector. Each detector is coupled to a photomultiplier and the output pulses are height-analyzed in 32 channels covering the nominal energy range of 30-100 Kev. The coded ma

Pelagic Archaea in the changing coastal Arctic (PACCA)Samples were collected in the bay of Kongsfjorden (Svalbard) in August 2007 and June 2008. Up to 8 stations located along a transect from a glacier towards the open sea were sampled weekly to examine temporal variation in microbial parameters. Abundances of bacteria and viruses were measured using flow cytometry and bacterial production was determined by 3H-leucine incorporation. Dark inorganic ca

NERC Biogeochemical Ocean Flux Study (BOFS) data in the Southern Ocean (1992)The aim of the Sterna 92 project was to measure the magnitude and variability of carbon and nitrogen fluxes during early summer in the Southern Ocean, with particular emphasis on rates and processes in the marginal ice zone. Data were collected at sites in the Bellingshausen Sea as part of a 2-ship Eulerian experiment; RRS James Clark Ross held her geographic position while the ice retreated past

Oceanic Particulate Inorganic Carbon as an Estimate of Calcification Measured during the JGOFS Equatorial Pacific Process Study (EQPAC)The Equatorial Pacific Process Study (EQPAC) was conducted along 140 deg W longitude during 1992. Four cruises took place: February 3 - March 9, March 19 - April 15, August 5 - September 18, and September 24 - October 21. A fifth benthic cruise and sediment trap legs were added. During the first cruise (TT007), 15 stations were occupied along 140 deg W longitude from 12 deg N latitude to 12 deg S
