attribute NC_GLOBAL acquisition_description String Survey design:\n \nAll sites were located at 6 to 9 meters depth.\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. A total of six transect lines, also marked with\neyebolts, were laid out at 10 m intervals. All octocorals present in 1 x 1 m\nquadrats along the 10-meter long transects were scored. In 2014 ten quadrats\nwere surveyed along each line. In 2015 and 2016 ten quadrats were scored along\neach transect line at Europa and Tektite and five randomly chosen quadrats\nwere surveyed at East Cabritte. The transect identifier \\\"transect_pos\\\" has\nvalues 0, 10, 20, 30, 40 or 50 which represent position& in meters within the\n50x10 survey area corresponding to each of the 6 transects (e.g. 20 = 20m).\n \nThe census at Booby Rock was conducted in a single day in which transects were\nrandomly placed along a 50 m line that was arbitrarily placed on a constant\ndepth contour. Only 4 1x1 m quadrats were surveyed along each transect. The\ntransect identifier (transect_pos) for transects at Booby Rock refers to\nposition along the 50 m line.\n \nYawzi and Deep Tektite surveys: 20 quadrats at each transect (3 transects)\n \nSampling methods:\n \nIdentifications 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. Sclerites from those samples were examined\nfor species identification.\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 farthest branch from the base (i.e.\nnot necessarily perpendicular to the substrate), regardless of whether the\ntips or base had living tissue. (Only colonies with some living tissue were\nmeasured). All measures rounded to the nearest cm with the exception of 5 cm\nwhich only includes colonies >= 5 cm. Starting in 2016, measures less than 5\ncm reflect colonies with thick branches which could only have <5 cm heights\ndue to partial mortality.

attribute NC_GLOBAL projects_0_description String NSF abstract:\nCoral reefs are exposed to a diversity of natural and anthropogenic disturbances, and the consequences for ecosystem degradation have been widely publicized. However, the reported changes have been biased towards fishes and stony corals, and for Caribbean reefs, the most notable example of this bias are octocorals (\"soft corals\"). Although they are abundant and dominate many Caribbean reefs, they are rarely included in studies due to the difficulty of both identifying them and in quantifying their abundances. In some places there is compelling evidence that soft corals have increased in abundance, even while stony corals have become less common. This suggests that soft corals are more resilient than stony corals to the wide diversity of disturbances that have been impacting coral corals. The best coral reefs on which to study these changes are those that have been studied for decades and can provide a decadal context to more recent events, and in this regard the reefs of St. John, US Virgin Islands are unique. Stony corals on the reefs have been studied since 1987, and the soft corals from 2014. This provides unrivalled platform to evaluate patterns of octocoral abundance and recruitment; identify the patterns of change that are occurring on these reefs, and identify the processes responsible for the resilience of octocoral populations. The project will extend soft coral monitoring from 4 years to 8 years, and within this framework will examine the roles of baby corals, and their response to seafloor roughness, seawater flow, and seaweed, in determining the success of soft corals. The work will also assess whether the destructive effects of Hurricanes Irma and Maria have modified the pattern of change. In concert with these efforts the project will be closely integrated with local high schools at which the investigators will host marine biology clubs and provide independent study opportunities for their students and teachers. Unique training opportunities will be provided to undergraduate and graduate students, as well as a postdoctoral researcher, all of whom will study and work in St. John, and the investigators will train coral reef researchers to identify the species of soft corals through a hands-on workshop to be conducted in the Florida Keys.\nUnderstanding how changing environmental conditions will affect the community structure of major biomes is the ecological objective defining the 21st century. The holistic effects of these conditions on coral reefs will be studied on shallow reefs within the Virgin Islands National Park in St. John, US Virgin Islands, which is the site of one of the longest-running, long-term studies of coral reef community dynamics in the region. With NSF-LTREB support, the investigators have been studying long-term changes in stony coral communities in this location since 1987, and in 2014 NSF-OCE support was used to build an octocoral \"overlay\" to this decadal perspective. The present project extends from this unique history, which has been punctuated by the effects of Hurricanes Irma and Maria, to place octocoral synecology in a decadal context, and the investigators exploit a rich suite of legacy data to better understand the present and immediate future of Caribbean coral reefs. This four-year project will advance on two concurrent fronts: first, to extend time-series analyses of octocoral communities from four to eight years to characterize the pattern and pace of change in community structure, and second, to conduct a program of hypothesis-driven experiments focused on octocoral settlement that will uncover the mechanisms allowing octocorals to more effectively colonize substrata than scleractinian corals on present day reefs. Specifically, the investigators will conduct mensurative and manipulative experiments addressing four hypotheses focusing on the roles of: (1) habitat complexity in distinguishing between octocoral and scleractinian recruitment niches, (2) the recruitment niche in mediating post-settlement success, (3) competition in algal turf and macroalgae in determining the success of octocoral and scleractian recruits, and (4) role of octocoral canopies in modulating the flux of particles and larvae to the seafloor beneath. The results of this study will be integrated to evaluate the factors driving higher ecological resilience of octocorals versus scleractinians on present-day Caribbean reefs.\nThis award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
