Light data in tanks from experiment on brooded coral larval, Taiwan, March 2011 (Cumbo et al, JEMBE, 2013) (MCR LTER & Climate Coral Larvae projects)

Abstract:

The physiological development of brooded larvae from the pocilloporid corals Pocillopora damicornis in southern Taiwan under elevated temperature and pCO2 was examined. These data include light measurements from experiments on the physiological development of brooded coral larvae conducted in March 2011. These data were published in Cumbo et al, JEMBE, 2013.

Methods & Sampling

Treatments were created in eight 150 L tanks, each filled with 120 L of filtered (1 um) seawater that was changed partially (20%) every day (at ~17:00 h). Tanks were individually heated (300 Wheaters, Taikong Corporation) and chilled (Aquatech Ac11 or Shyeh Duwai Enterprise), with the temperature regulated using programmable, digital controllers (±0.1 °C, AquaControllers, Neptune Systems). Illumination was provided by metal halide (Phillips 150 W 10,000 k) and fluorescent (39 W, Phillips T5 460 nm) bulbs to create a mean light intensity of 268± 17 µmol quanta m-2 s-1 (±SE, n=64). The light intensity was selected to approximate that found at the collection depth of the parent colonies in March.

Treatments were created by blending CO2 with air, and continually assessing the mixture through an Infra Red gas analyzer (S151, Qubit Systems), which dynamically adjusted the flow of CO2 to maintain desired levels. The gas mixture was supplied through an air stone to four of the eight tanks, with others supplied with compressed air (i.e., ambient pCO2). The conditions in the tanks were analyzed for pH, salinity, temperature, and total alkalinity (TA) using standard operating procedures (Dickson et al., 2007), and the program CO2SYS (Lewis and Wallace, 1998) to calculate DIC parameters. The gas mixing technology and the methods for seawater analyses essentially are identical to those we have used before (see Dufault et al., 2012; Edmunds, 2011). In the present analysis, the calculated TA values of certified reference materials supplied by Dr. Andrew Dickson, Scripps Institute of Oceanography (batch no. 98 and 107), were determined within a mean of 1% of the certified value.

The incubation system created target temperatures of ~24.00 °C versus 30.50 °C, and target pCO2 values of ambient versus 86.1 Pa, and an irradiance of ~268 µmol quanta m-2 s-1. Conditions in the tanks were measured at least daily using a certified digital thermometer (Model 15-077-8, Fisher Scientific,±0.05 °C), a cosine-corrected quantum light meter (Li-Cor LI-192 attached to an LI-1400), and a sample of water withdrawn from each tank for pH, salinity, and TA analysis.

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.
