Description

This study characterizes the metabolism of the endemic Antarctic coral Flabellum impensum by measuring oxygen consumption and metabolic enzyme activity. This dataset is a comparison of Flabellum impensum metabolism with other corals reported in the literature and is from a table extracted from the paper,

Metabolism of an Antarctic solitary coral, Flabellum impensum. 2013, by Lara V. Henry and Joseph J. Torres found in the Journal of Experimental Marine Biology and Ecology, 449 (2013) 17-21. (Table 1)

Methods & Sampling

Dataset acquisition description

Corals were collected with a 10 m otter trawl by the RVIB Nathaniel B. Palmer off the Western Antarctic Peninsula during March 2010. The corals were collected off Anvers Island at 600 m and off Charcot Islands at 200 meters depth.

Measurements were taken on 9 specimens.

(See Henry and Torres paper cited above for more details.)

Data Processing Description

Dataset Processing Description

Individuals with no signs of trauma were allowed to recover in pre-chilled seawater in 0 degrees from 12 to 22 hours before being used in experiments.

(See Henry and Torres paper cited above for more details.)
