Skeletal density for crustose coralline algae reared in natural and experimental temperature and pCO2 conditions

Abstract:

This dataset contains skeletal density for crustose coralline algae reared in natural and experimental conditions (factorially crossed temperature (~6.5, 8.5, and 12.5 °C) and pCO2 (~350, 490, 890, and 3200 µatm)). Skeletal density was quantified using a micro-CT scanner.

Methods & Sampling

This dataset contains skeletal density in crustose coralline algae cultured in experimental conditions (factorially crossed temperature (~6.5, 8.5, and 12.5 °C) and pCO2 (~350, 490, 890, and 3200 µatm)). The experiment was run for 125 days, starting in October 2015.

Skeletal density was quantified using Micro-CT imaging conducted at the Preclinical Imaging Research Centre (PIRC), Robarts Research Institute, University Of Western Ontario, using a micro-CT scanner (GE Healthcare, eXplore Locus RS-9) at a peak x-ray energy of 80 kVp and a tube current of 450 uA.

Specimens used in the experiments were collected from the Gulf of Maine (44.431591 N, -68.121289 E) and Adak Island, Alaska (51.784143 N, -176.432640 E).

Data Processing Description

BCO-DMO Processing:
- replaced spaces with underscores in parameter names;
- rounded Density column to two decimal places.

Instruments

Computerized Tomography (CT) Scanner

Supplied Name: micro-CT scanner

Supplied Description:

Skeletal density quantified using Micro-CT imaging conducted at the Preclinical Imaging Research Centre (PIRC), Robarts Research Institute, University Of Western Ontario, using a micro-CT scanner (GE Healthcare, eXplore Locus RS-9) at a peak x-ray energy of 80 kVp and a tube current of 450 uA

Instrument Type

Generic Name: Computerized Tomography (CT) Scanner

Acronym: CT Scanner

Generic Description:

A CT scan makes use of computer-processed combinations of many X-ray measurements taken from different angles to produce cross-sectional (tomographic) images (virtual "slices") of specific areas of a scanned object.

Parameters

Date and time formats are described in python strftime() syntax.
