Samples included in this dataset were collected from May 11 - June 6, 2002, and July 19 - August 21, 2002 from the United States Coast Guard Icebreaker Healy (WAGB-20). Samples collected on the Healy were funded through the Shelf-Basin Interactions project, which is funded by both the National Science Foundation and the Office of Naval Research. INSTRUMENT DESCRIPTION: All water samples were collected using a rosette bottle system on a CTD. A van Veen grab (0.1 m2 sediment grab), weighted with 32 kg of lead was used in the collection of surface sediment samples and fauna. All sediment grain size samples were collected from van Van grabs. Fauna were collected on 1 mm sieve mesh and preserved in 10% buffered formallin. TOC, TON, and C/N samples were also taken from van Veen grabs. A multi (4 barrel) Haps corer (each core = 0.0133 m2) was used to collect sediment cores , which were used for sediment metabolism (respiration) measurements. For more information on the HAPS core, see: Kanneworff, E. & Nicolaisen, W. The "HAPS:" A frame supported bottom corer. Ophelia Supplement 10, 119-129 (1973). DATA FORMAT File Names (Formats): HLY0201-JOSSMaster.txt (Tab delimited text file) HLY0201-JOSSMaster.xls (MS XL 5.0/95 file) NOTE: all of our Excel files will be saved in 5.0/95 version, so most can access the file. Naming Convention: CruiseName-"JOSS"Variable.filetype (ex. HLY0201-JOSSO-18.txt) Files will try to adhere to this convention, but sometimes cruises from the same year will be combined for convenience, and the name will reflect the year and the variables included. Data Format and Layout: Ship - HLY: "Healy", USCG Icebreaker WAGB-20 Year - 02 : year, 2002 Cruise# - 01 : cruise number for the ship for that year Station# - sequentially numbered from beginning to end of cruise Station Name - based on transect names, the lower the number the less the depth HV : Herald Valley WHS : West Hanna Shoal EHS : East Hanna Shoal BC : Barrow Canyon EB : East Barrow HC : Hanna Canyon Lat., Long., Date/Time - self-explanatory Depth - bottom depth in meters Cast# - CTD cast from which samples were taken, matches JOSS event log Bottle - CTD bottle from which samples were taken Bottle Depth - depth at which bottle was tripped Bot Temp - temp of bottom water (íC) Bot Sal - salinity of bottom water (psu) Bot Oxygen - dissolved oxygen of bottom water (ml/l) Bot sigma t - sigma t of bottom water Del 0-18 - delta 18O of bottom water (per mil) Bot Chl-a - chlorophyll concentration of bottom water (mg/m3) Integrated Chl-a - chlorophyll concentration integrated throughout the water column (mg/m2) Sed Chl-a - concentration chlorophyll that has settled on 1 m2 (mg Chl/m2) Abundance - number of animals per m2 (no/m2) Biomass (g/m2) - grams of biomass per m2 Biomass (gC/m2) - grams of carbon per m2 Taxa# - number of taxa per m2 Sed modal size - median sediment grain size phi class Sed Phi size- percent of grain size fraction, 0 phi-largest, 5 phi-smallest TOC - total organic carbon (mg/g) TON - total organic nitrogen (mg/g) C/N - carbon-to-nitrogen ratio Delta 13C - (per mil) O2UR - sediment oxygen uptake rate (mmol O2/m2/d) s.d. - standard deviation of two O2UR experiments Data Version Number and Date: Version 1, 2/11/04Software Compatibility: This dataset will be posted in both Microsoft Excel 5.0/95 and as a tab-delimited text file.
