Methods & Sampling

Preparation of extracts: Coral samples of orange and red colonies of Montipora capitata were collected in Kaneohe Bay, Oahu. Frozen samples were extracted in Millipore® water, which was replaced daily for 3 d. Extracts were filtered, lyophilized, and weighed. Extracts were resuspended in Millipore® water to a concentration of 10 mg/ml.

Chemical fingerprinting: To generate chemical profiles, extracts were injected onto a Waters Alliance® 2695 High Performance Liquid Chromatography (HPLC) system (Phenomenex Syneri Hydro RP 4 um column; 250 x 4.6 mm; linear gradient from 100% water+0.1% acetic acid to 100% methanol+0.1% acetic acid) interfaced with a Waters 2998 Photodiode Array Detector. Spectra at 254 nm were generated. Each peak observed at the same retention time in each extract represents a particular compound, relative concentrations of which can be compared between extracts.

Data Processing Description

Peaks from the 254 nm spectra were integrated to generate areas under the curve (in absorbance units). These areas can then be compared among extracts.

BCO-DMO Processing:
- added conventional header with dataset name, PI name, version date
- renamed parameters to BCO-DMO standard or to match other datasets in project
- replaced blanks with underscores
- replaced color_morph code with color name: 1=orange; 2=red

Generic Description:

A High-performance liquid chromatograph (HPLC) is a type of liquid chromatography used to separate compounds that are dissolved in solution. HPLC instruments consist of a reservoir of the mobile phase, a pump, an injector, a separation column, and a detector. Compounds are separated by high pressure pumping of the sample mixture onto a column packed with microspheres coated with the stationary phase. The different components in the mixture pass through the column at different rates due to differences in their partitioning behavior between the mobile liquid phase and the stationary phase.

Date and time formats are described in python strftime() syntax.
