Description

This dataset includes Globobulimina turgida stable isotopes of carbon and oxygen from sediment cores collected on R/V Endeavor EN524 on the continental shelf off New England (40.43 N 70.5 W), May 2013

Methods & Sampling

Dataset acquisition description

Foraminiferal bearing sediments were collected using MC800 multicorer. All samples were from one multicore deployment (MC14), from two different multicores (CTG designated mostly for CellTracker Green studies; DC designated mostly for downcore studies). Each was sliced into selected 1-cm intervals. In the CTG core, live specimens were distinguished from dead using CellTracker Green CMFDA. Globobulimina turgida specimens were isolated from sediments and air dried. Pools of 10-15 conspecifics (depending on individual sizes) were analyzed using the Isocarb (common acid bath) prep system on the NOSAMS VG Prism-II SIRMS.

Instruments

Mass Spectrometer

Supplied Name: NOSAMS VG Prism-II SIRMS

Supplied Description:

Instrument Type

Generic Name: Mass Spectrometer

Acronym: Mass Spec

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB16/

Generic Description:

General term for instruments used to measure the mass-to-charge ratio of ions; generally used to find the composition of a sample by generating a mass spectrum representing the masses of sample components.

Multi Corer

Supplied Name: MC800 multicorer

Supplied Description:

Used to collect sediment samples

Instrument Type

Generic Name: Multi Corer

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

Generic Description:

The Multi Corer is a benthic coring device used to collect multiple, simultaneous, undisturbed sediment/water samples from the seafloor. Multiple coring tubes with varying sampling capacity depending on tube dimensions are mounted in a frame designed to sample the deep ocean seafloor. For more information, see Barnett et al. (1984) in Oceanologica Acta, 7, pp. 399-408.
