attribute NC_GLOBAL acquisition_description String Survey design:  \n All sites were located at 6 to 9 meters depth.\\u00a0\n \nCensuses at East Cabritte, Europa and Tektite were based on 50x10m areas that\nwere arbitrarily selected and permanently marked with stainless steel eyebolts\nat the corners of the sites.\\u00a0 A total of six transect lines, also marked\nwith eyebolts, were laid out at 10 m intervals. All octocorals present in 1 x\n1 m quadrats along the 10-meter long transects were scored. In 2014 ten\nquadrats were surveyed along each line.\\u00a0 In 2015 and 2016 ten quadrats\nwere scored along each transect line at Europa and Tektite and five randomly\nchosen quadrats were surveyed at East Cabritte.\\u00a0 The transect identifier\n\\\"transect_pos\\\" has values 0, 10, 20, 30, 40 or 50 which represent position\nin meters within the 50x10 survey area corresponding to each of the 6\ntransects (e.g. 20 = 20m).\\u00a0\\u00a0\n \nThe census at Booby Rock was conducted in a single day in which 2 transects\nwere randomly placed along a 50 m line that was arbitrarily placed on a\nconstant depth contour.\\u00a0 Only 4 1x1 m quadrats were surveyed along each\ntransect. The transect identifier (transect_pos) for transects at Booby Rock\nrefers to position along the 50 m line.\n \nSampling methods:  \n Identifications were based on traits visible in the field, and samples of\nrepresentative colonies were collected for further analysis in cases in which\nfield identification was uncertain.\\u00a0 Sclerites from those samples were\nexamined for species identification.\n \nColony heights were measured as the maximum distance from the base of the\noctocoral colony until the farthest tips of the branch (i.e. not necessarily\nperpendicular to the substrate).\\u00a0 All measures rounded to the nearest cm\nwith the exception of 5 cm which only includes colonies >= 5 cm.\\u00a0\nStarting in 2016, measures less than 5 cm reflect colonies with thick branches\nwhich could only have <5 cm heights due to partial mortality.\n \nTwo height measures are present, height of living tissue, which only includes\nthat part of the axis with living tissue and total height which is the\ndistance from the base to the tip of the tallest branch regardless of whether\nthe tips or base had living tissue.\\u00a0 (Only colonies with some living\ntissue were measured).\n \nSpecies names for field_codes in this dataset\\u00a0can be found in the related\ndataset: [https://www.bco-dmo.org/dataset/733063](\\\\\"https://www.bco-\ndmo.org/dataset/733063\\\\\")\n \nThese data are a continuation of BCO-DMO project \\\"Ecology and functional\nbiology of octocoral communities\\\" ([http://www.bco-\ndmo.org/project/562086](\\\\\"https://www.bco-dmo.org/project/562086\\\\\"))

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nDisturbance and subsequent recovery have been key factors in the dynamics of coral reef populations, but in the Caribbean, there has been a steady decline in the abundance of hard corals accompanied by increased abundance of algae. This characterization overlooks the observation that at some sites for which there are quantitative data, the abundances of octocorals (sea fans and sea plumes) have increased. Closer inspection of those data reveals that octocorals have also declined at times, but unlike hard corals, they recovered and are now more abundant in at least some locations than 30 years ago. The change in abundances of these organisms would appear to due to the greater resilience of octocorals. The damage inflicted by Hurricanes Irma and Maria on the south shore of St. John, U.S. Virgin Is. provides a window into these processes. Abundances of hard corals on these reefs have been monitored for the past 30 years and the octocorals have been followed for the past 4 years. Colonization of the newly opened space on the reef will be studied to determine if further shifts in abundances can be expected and to understand the basis for the greater resilience of octocoral populations. Characterizing the resilience of octocorals relative to hard corals will have implications for the fate of Caribbean reefs in a world subject of increasing levels of stress. This will be of importance to policy makers and managers, because hard corals and octocorals provide substantially different ecosystem services. In addition to its impact on our fundamental understanding of reef processes, the grant will support the training of graduate students.\nCoral reefs have been recognized to be disturbance driven systems for over 50 years and disturbance has been considered to be important in maintaining diversity of reef communities. However, the past 30 years has been characterized by declines in the abundances of scleractinians, often associated with acute events such as hurricanes and bleaching events. A knowledge of the effects of disturbance and subsequent recovery that occurs during these events is critical to understanding the changes in reef structure that have occurred in the last 30 years. At sites for which there are data, changes in the relative abundance of scleractinians and octocorals appear to coincide with disturbance followed by octocoral recovery and a lack of scleractinian recovery. This change must reflect changes in larval supply, settlement, and/or survival, and those differences should be greatest following disturbance. The effects of Hurricanes Irma and Maria on the south shore of St. John provide the opportunity to characterize recruitment following disturbance and identify the processes that may limit successful recruitment on contemporary reefs. Data are already available on the abundance of octocoral and scleractinian species over the past 4 years, and annual censuses have provided data on octocoral recruitment and survival and species level characterizations of octocoral abundances. Recruitment and survival are also being related to spatial complexity of the habitat at the scale of mm and cm and the effects on hurricane driven changes in that spatial complexity will also be assessed. The frequency and intensity of disturbances will at the least continue at historical or greater levels. The comparison of data from before and now after disturbance will provide a powerful assessment of the resilience of octocorals and scleractinians and the role of recruitment and recruit survival in their relative resilience. Thus the effects of Hurricanes Irma and Maria provide a window on the nature of future reefs.\nNote: This project is closely associated with the project \"Ecology and functional biology of octocoral communities\".
