Description

Daily water chemistry measurements from a larval growth experiment culturing Olympia oysters in 50 unique combinations of temperature, salinity, and pCO2 over up to 17 days of larval life.

Methods & Sampling

We cultured Olympia oyster larvae in 50 unique combinations of temperature, salinity, and pCO2. Larval methods are described in growth experiment dataset, but to collect water samples, we measured water temperature and salinity with an Orion Star A329 conductivity meter every two days prior to water changes. We collected pH samples in 20ml plastic scintillation vials, poisoned them 10 µl of mercuric chloride, and stored at room temperature. Roughly one month later, we measured samples for pH using a diode array spectrophotometer (Agilent 8453A UV-VUS) and DIC with a DIC analyzer (Appolo SciTech AS-C3). We then used all parameters collected to calculate pCO2 and Aragonite Saturation with CO2SYS.

Data Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- re-formatted date from mdyy to yyyy-mm-dd
- reduced number of significant digits of pH, pCO2, and Ar to reflect sampling precision methods

Instruments

Apollo SciTech AS-C3 Dissolved Inorganic Carbon (DIC) analyzer

Supplied Name: Appolo SciTech AS-C3 DIC analyzer

Supplied Description:

Instrument Type

Generic Name: Apollo SciTech AS-C3 Dissolved Inorganic Carbon (DIC) analyzer

Acronym: Apollo SciTech AS-C3

Generic Description:

A Dissolved Inorganic Carbon (DIC) analyzer, for use in aquatic carbon dioxide parameter analysis of coastal waters, sediment pore-waters, and time-series incubation samples. The analyzer consists of a solid state infrared CO2 detector, a mass-flow controller, and a digital pump for transferring accurate amounts of reagent and sample. The analyzer uses an electronic cooling system to keep the reactor temperature below 3 degrees Celsius, and a Nafion dry tube to reduce the water vapour and keep the analyzer drift-free and maintenance-free for longer. The analyzer can handle sample volumes from 0.1 - 1.5 milliliters, however the best results are obtained from sample volumes between 0.5 - 1 milliliters. It takes approximately 3 minutes per analysis, and measurement precision is plus or minus 2 micromoles per kilogram or higher for surface seawater. It is designed for both land based and shipboard laboratory use.

Conductivity Meter

Supplied Name: Orion Star A329

Supplied Description:

Instrument Type

Generic Name: Conductivity Meter

Generic Description:

Conductivity Meter - An electrical conductivity meter (EC meter) measures the electrical conductivity in a solution. Commonly used in hydroponics, aquaculture and freshwater systems to monitor the amount of nutrients, salts or impurities in the water.

Spectrophotometer

Supplied Name: Agilent 8453A UV-VUS diode array spectrophotometer

Supplied Description:

Instrument Type

Generic Name: Spectrophotometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB20/

Generic Description:

An instrument used to measure the relative absorption of electromagnetic radiation of different wavelengths in the near infra-red, visible and ultraviolet wavebands by samples.
