Tissue thickness from coral cores taken in the central equatorial Pacific

Abstract:

Coral cores were collected in the central equatorial Pacific (Central Pacific Coral reefs, -5 to 5 latitude, Dongsha Atoll, Curacao, Barbados, Martinique coral reefs). The thickness of the tissue in each core was measured as an index of biomass or energetic reserve.

Description

Methods & Sampling

These data were published in Mollica et al., 2019

All cores were collected and analyzed using the same methods. Only live colonies were cored, establishing the top age, vertically i.e., parallel to the upward growth axis, and using either a pneumatic drill fitted with 3-cm diameter diamond tip coring bit or an hydraulic drill fitted with an 8-cm diameter bit. Core holes were sealed with a cement cap and underwater epoxy, secured flush with the colony surface to facilitate overgrowth of tissue and wound closure (e.g. Matson 2011), a 6 to 36-month process depending on the rate of coral growth and diameter of core. All cores were first air dried in the field, then oven dried at 60 deg C.

Location: Central Pacific Coral reefs, -5 to 5 latitude, Dongsha Atoll, Curacao, Barbados, Martinique coral reefs.

Data Processing Description

The thickness of the tissue in each core was measured as an index of biomass or energetic reserve. The vertical distance between the top of the core and the topmost dissepiment upon which the base of the tissue rests (e.g. Barnes and Lough 1992) was measured on a cut slab using a Nikon SMZ1500 stereomicroscope and SPOT imaging software (e.g. Barkley et al. 2018).
