The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Data from surveys of Eunicea flexusa colonies on St. John, VI National Park from 2014 (NCEI Accession 0277897) |
| Abstract: | This dataset contains biological and survey - biological data collected at Virgin Islands and Virgin Islands National Park during deployments Edmunds_StThomas and Edmunds_VINP from 2014-08-06 to 2014-08-14. These data include depth and species. These data were collected by Howard Lasker of State University of New York at Buffalo as part of the "Ecology and functional biology of octocoral communities (VI Octocorals)" and "LTREB Long-term coral reef community dynamics in St. John, USVI: 1987-2019 (St. John LTREB)" projects. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-04-19. The following is the text of the dataset description provided by BCO-DMO: Data from surveys of Eunicea flexusa colonies that were found in close proximity.

| Supplementary information: | Acquisition Description: Methodology from Gambrel, B. and Lasker, H.R., 2016 Since physical effects of octocoral−octocoral proximity were common, we examined the physical effects on different species by comparing their interspecific interactions with 75 colonies of E. flexuosa . The choice of E. flexuosa was based on its abundance and on the reliability of identifying E. flexuosa colonies in the field. We sampled at East Cabritte, as the high octocoral density there led to a high incidence of interactions. We searched for E. flexuosa within the same 500 m2 area as the belt transects and selected colonies based on the presence of interspecific interactions. Tissue damage due to proximity between octocorals was categorized into first and second-degree damage. First-degree damage was defined as slight signs of abrasion including fewer polyps or retracted polyps in contact areas and lightly eroded calyces, whereas second-degree damage involved the erosion of the soft tissue past the surface layer, sometimes down to the proteinaceous skeleton. If an octocoral had branches exhibiting both first and second-degree damage, it was scored as having the more severe, second-degree damage. Colonies in close proximity were identified to species and were assessed for damage and asymmetry. Fisher’s exact tests of independence were used in R to test for the effect of the species pairing on damage type and the presence or absence of colony asymmetry. |
