Description

The physiological development of brooded larvae from the pocilloporid corals Pocillopora damicornis and Seriatopora caliendrum in southern Taiwan was examined.

These data include the larval release schedule relative to lunar day in June and July, 2010.

These data are published in Cumbo, VR, Fan TY, Edmunds PJ. (2012) Physiological development of brooded larvae from two pocilloporid corals in Taiwan. Marine Biology 159: 2853-2866. DOI 10.1007/s00227-012-2046-y. See Figs. 1a and 2.

Methods & Sampling

In June, larvae were harvested from 11 colonies of P. damicornis and 12 colonies of S. caliendrum collected from 5 m depth at Hobihu Reef (Nanwan Bay) on June 11, one day before the new moon. In July, 12 colonies of P. damicornis were collected from the same location on 9 July 2011, 2 days before the new moon. All colonies were ~20-cm diameter and were transported to the National Museum of Marine Biology and Aquarium (NMMBA) and placed in individual flow-through aquaria for larval release. In the larval release area, aquaria were supplied with filtered seawater (~50 lm) and exposed to sunlight shaded to a mean maximum intensity of photosynthetically active radiation (PAR, 400-700 nm) at 1200 hours of ~121 lmol quanta m-2 s-1 (measured with a LiCor LI-192SA sensor). Larvae were collected in catchers fitted with plankton mesh (110 um) and positioned to receive seawater overflowing from each aquarium. Catchers were inspected at 0600 hours for S. caliendrum and 0745 hours for P. damicornis, and any larvae found were counted. The earlier collection time for S. caliendrum was necessary to obtain swimming larvae prior to their rapid settlement.

Instruments

LI-COR LI-192 PAR Sensor

Supplied Name: LI-COR LI-192SA PAR

Supplied Description:

LI-COR LI-192 SA sensor

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.
