Spring 2011 Sediment/Permafrost Master Data Sheet

Methods & Sampling

Dataset acquisition description

Spring 2011 Sediment/Permafrost Master Data Sheet

Collection Type: Gravity core; Drill core
Sampling Area: East Siberian Arctic Shelf
A negative depth value represents an overlying water sample
Rates were measured at stations 13 and 23 only.
Rates were quantified according to Orcutt et al. 2005 & Joye et al. 2010 in triplicate sub-samples plus killed controls
Geochemistry data was obtained according to Joye et al. 2011
MOG=methanogenesis
AOM=anaerobic oxidation of methane
CH4: methane
CO2: carbon dioxide

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes
- Generated from original file "0908788_Joye_Spring-2011_ Summary.xlsx", Sheet: "Sediment Master" contributed by Samantha Joye
- Parameter names edited to conform to BCO-DMO naming convention found at Choosing Parameter Name
- Lat and Lon converted to decimal degrees
- "nd" (no data) inserted into blank cells
- blank rows removed
- Spaces removed from Station, Collection Type and Date values to enable levelizing of data
- "B.D.L." converted to "BDL" (periods removed) to avoid potential data errors downstream
- "N.D." converted to "nd" (periods removed) to avoid potential data errors downstream and for consistency with "nd" (see above)

Instruments

Drill Core

Supplied Description:

Instrument Type

Generic Name: Drill Core

Generic Description:

A core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core.

Core drills are used frequently in mineral exploration where the coring may be several hundred to several thousand feet in length. The core samples are recovered and examined by geologists for mineral percentages and stratigraphic contact points. This gives exploration companies the information necessary to begin or abandon mining operations in a particular area.

Gravity Corer

Supplied Name: Gravity Core

Supplied Description:

Instrument Type

Generic Name: Gravity Corer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/51/

Generic Description:

The gravity corer allows researchers to sample sediment layers at the bottom of lakes or oceans. The coring device is deployed from the ship and gravity carries it to the seafloor. (http://www.whoi.edu/instruments/viewInstrument.do?id=1079).
