Methods & Sampling

Buoyant weights of the corals and algae were recorded at the beginning of the incubation and after 3 weeks in the treatments. The difference between the initial and final buoyant weight was converted to dry weight of skeleton using the aragonite density of 2.93 g cm-3 for A. pulchra and calcite density of 2.71 g cm-3 for L. kotschyanum , in accordance with the mineral form of CaCO3 deposited by each taxon. Rates of net calcification were normalized to the area of organisms estimated using wax dipping (Stimson and Kinzie 1991 ).

Data Processing Description

To test for differences in treatment conditions in the tanks, temperature and pCO2 in the tanks were analyzed with a two-factor partially nested ANOVA in which treatment (pCO2 or temperature) was a fixed effect and tank a random nested factor.

BCO-DMO Processing:
- added conventional header with dataset name, PI name, version date, reference information
- renamed parameters to BCO-DMO standard
- added site, lab, lat, lon columns
- sorted by month, species, pCO2, tank

Instruments

Automatic titrator

Supplied Name:

Supplied Description:

T50, Mettler-Toledo, Switzerland

Instrument Type

Generic Name: Automatic titrator

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB12/

Generic Description:

Instruments that incrementally add quantified aliquots of a reagent to a sample until the end-point of a chemical reaction is reached.

LI-COR LI-193 PAR Sensor

Supplied Name:

Supplied Description:

4-pi quantum sensor LI-193 and a LiCor LI-1400 meter data logger.

Instrument Type

Generic Name: LI-COR LI-193 PAR Sensor

Acronym: LI-COR LI-193 PAR

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0458/

Generic Description:

The LI-193 Underwater Spherical Quantum Sensor uses a Silicon Photodiode and glass filters encased in a waterproof housing to measure PAR (in the 400 to 700 nm waveband) in aquatic environments. Typical output is in micromol s-1 m-2. The LI-193 Sensor gives an added dimension to underwater PAR measurements as it measures photon flux from all directions. This measurement is referred to as Photosynthetic Photon Flux Fluence Rate (PPFFR) or Quantum Scalar Irradiance. This is important, for example, when studying phytoplankton, which utilize radiation from all directions for photosynthesis. LI-COR began producing Spherical Quantum Sensors in 1979; serial numbers for the LI-193 begin with SPQA-XXXXX (licor.com).

Optode

Supplied Name:

Supplied Description:

PreSens dipping oxygen optodes (PSt3) connected to Fibox 3 transmitters (Precision Sensing GmbH, Germany).

Instrument Type

Generic Name: Optode

Generic Description:

An optode or optrode is an optical sensor device that optically measures a specific substance usually with the aid of a chemical transducer.

pH Sensor

Supplied Name:

Supplied Description:

Orion 3-stars, Thermo Scientific, USA, mounted with a combination pH probe (Orion Ross Ultra,
Thermo Scientific, USA)

Instrument Type

Generic Name: pH Sensor

Generic Description:

An instrument that measures the hydrogen ion activity in solutions.

The overall concentration of hydrogen ions is inversely related to its pH. The pH scale ranges from 0 to 14 and indicates whether acidic (more H+) or basic (less H+).
