Methods & Sampling

Dataset acquisition description

Larval respiration was measured in a confined respirometer use a Ruthenium-based optrode (FOXY-R, 1.58 diameter, Ocean Optics) connected to a spectrophotometer (USB2000, Ocean Optics) and interfaced with a computer running the manufacturers software (OOISensor, version 1.00.08). The optrode was calibrated using a zero solution (0.01 M Na2B4O7·10H2O supersaturated with Na2SO3) and 100% air saturation usingwater-saturated air at the treatment temperature. Tomeasure respiration, 6 larvae were removed from the tubs in the treatment tanks and placed into 2-mL glass Wheaton vials filled with filtered seawater from the same treatment tank and sealed with Parafilm. A study conducted concurrently with the present analysis demonstrated that respiration of P. damicornis larvae in identical vials could be measured accurately with 5 larvae vial-1 (Edmunds et al., 2011).

Initial O2 concentration in the seawater was determined before the vials were sealed, and vials without larvae used as controls. Larvae in the sealed vials were incubated at their temperature treatments for 1.5-2 h in the dark using water baths set to the temperature of the respective treatments (±0.1 °C, Hipoint, models LC-06 and LC-10); vials were carefully moved throughout the incubations to ensure the seawater remained mixed. Incubation timeswere selected to ensure O2 concentrations remained >75% saturation. On completion of the incubations, vials were removed from the water baths, gently inverted to mix the seawater, and analyzed for O2 saturation. O2 saturation was converted to concentration using tabulated values of O2 solubility (N. Ramsing and J. Gundersen at http://www.unisense.com [based on Garcia and Gordon, 1992]) and the temperature and salinity of the seawater, and the change in O2 concentration used to calculate O2 flux after adjusting for controls. The respiration rates are expressed as nmol O2 mg protein-1 min-1.

The 'ambient' and 'high' pCO2 levels: 49.4 Pa versus 86.2 Pa
The 'ambient' and 'high' temperatures: 24.00 °C [ambient] versus 30.49 °C

LI-COR LI-192 PAR Sensor

Supplied Name: LI-COR LI-192 light sensor

Supplied Description:

cosine-corrected quantum light meter (Li-Cor LI-192 attached to an LI-1400)

Instrument Type

Generic Name: LI-COR LI-192 PAR Sensor

Acronym: LI-COR LI-192 PAR

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0120/

Generic Description:

The LI-192 Underwater Quantum Sensor (UWQ) measures underwater or atmospheric Photon Flux Density (PPFD) (Photosynthetically Available Radiation from 360 degrees) using a Silicon Photodiode and glass filters encased in a waterproof housing. The LI-192 is cosine corrected and features corrosion resistant, rugged construction for use in freshwater or saltwater and pressures up to 800 psi (5500 kPa, 560 meters depth). Typical output is in um s-1 m-2. The LI-192 uses computer-tailored filter glass to achieve the desired quantum response. Calibration is traceable to NIST. The LI-192 serial numbers begin with UWQ-XXXXX. LI-COR has been producing Underwater Quantum Sensors since 1973.

These LI-192 sensors are typically listed as LI-192SA to designate the 2-pin connector on the base of the housing and require an Underwater Cable (LI-COR part number 2222UWB) to connect to the pins on the Sensor and connect to a data recording device.

The LI-192 differs from the LI-193 primarily in sensitivity and angular response.
193: Sensitivity: Typically 7 uA per 1000 umol s-1 m-2 in water. Azimuth: < ± 3% error over 360° at 90° from normal axis. Angular Response: < ± 4% error up to ± 90° from normal axis.
192: Sensitivity: Typically 4 uA per 1000 umol s-1 m-2 in water. Azimuth: < ± 1% error over 360° at 45° elevation. Cosine Correction: Optimized for underwater and atmospheric use.
