Description

Spring 2012 - Turnover Rates

Methods & Sampling

2012 Arcitc Sediment/Permafrost Turnover Rates

Collection Type: Gravity core; Drill core
Negative depth values represent overlying water samples
Rates were measured at stations 13 and 23 only.
Rate samples were measured according to Orcutt et al. 2005

Instruments

Drill Core

Supplied Description:

Collection Type: Gravity core; Drill core

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:

Collection Type: Gravity core; Drill core

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).
